Issue196 范文

"Technology creates more problems than it solves, and may threaten or damage the quality of life."

Whether technology enhances or diminishes our overall quality of life depends largely on the type of technology one is considering. While mechanical automation may have diminished our quality of life on balance, digital automation is doing more to improve life than to undermine its quality.

First consider mechanical automation, particularly assembly-line manufacturing. With automation came a loss of pride in and alienation from one's work. In this sense, automation both diminished our quality of life and rendered us slaves to machines in our inability to reverse "progress." Admittedly, mechanical automation spawned entire industries, creating jobs, stimulating economic growth, and supplying a plethora of innovative conveniences. Nevertheless, the sociological and environmental price of progress may have outweighed its benefits.

Next consider digital technology. Admittedly, this newer form of technology has brought its own brand of alienation, and has adversely affected our quality of life in other ways as well. For example, computer automation, and especially the Internet, breeds information overload and steals our time and attention away from family, community, and coworkers. In these respects, digital technology tends to diminish our quality of life and create its own legion of human slaves.

On the other hand, by relegating repetitive tasks to computers, digital technology has spawned great advances in medicine and physics, helping us to better understand the world, to enhance our health, and to prolong our lives. Digital automation has also emancipated architects, artists, designers, and musicians, by expanding creative possibilities and by saving time. Perhaps most important, however, information technology makes possible universal access to information, thereby providing a democratizing influence on our culture.

In sum, while mechanical automation may have created a society of slaves to modern conveniences and unfulfRling work, digital automation holds more promise for improving our lives without enslaving us to the technology. 111

With the development of the high technology, modern people live a much more contented life. In the mean time, the fast changing technique also carries us lots of trouble. In certain cases, we have to say, with the evolution of technology, new inventions bring us more threat and damage in our quality of life. Someone even draw to an absolutely conclusion that we should restrain the attempt on new technology. However, in my point of view, it is the human ethic rather than the technique that should be limited. I heartfully promote the technical achievement for the following reasons: (技术只是作为一种手段,本身没有好坏之分。所以应该鼓励技术的发展,用伦理道德限制使用者来避免技术产物带来的危害。全文技术和技术产物是两个概念。技术的负面影响是源于技术的使用,而不是技术本身)

The technology itself is a tool that should be used for promotion of production, saving of time, and decrease of cost. We create new technology to meet这个改得好 the desire of the most effective way of life in good fields, or some times, in bad fields. We might laugh at someone who complains a dictionary for the reason that it provides us some bad information. As one should be objective and see the good information a dictionary contented also. For the same reason, we have to say it might be not so wise if a person have the similar complain on the technology. As a tool, technology itself works exactly like a dictionary as its main function is hard to be judged as "good" or "bad" as it is for the objective efficiency.  (我们不应该因为字典提供不好的信息就抱怨字典,同样作为一种工具,技术本身是客观中性的,没有好坏之分)

In history, technology does help a lot in the development of human life. Such example can be seen everywhere: the technical skill of the fire helps man prepare cooked food, which greatly deduced the gastrointestinal disease and prolonged the expected living time. The metallurgy give us a chance that we can conquer the surrounding which have a harder density than human bones and fresh by using manmade material. The industry revolution, with numerous invitations it carried to us, greatly reduced labor force and stimulated the development of technology itself. The bulb give us light in family life in every evening; the TV as well as other radiocasting shows us a exciting world; the camera records our wonderful memory; and the computer connect our privet life to the whole world by internet. 火器的运用,金属,工业革命,照明电力,无线传媒,数字电子按照科技的发展程度分别对应利。

It is undeniable that the technical inventions also bring us lots of disadvantages. Death always carries with the invention of power. The cold weapon with the usage of metal is with the record of injury, tear and blood in history. In industry revolution, we created the gun and other weapons, which are wildly used in the world war. We use candle bomb illumes the war field and our evening time have to be filled up with nonsense soup shows or junky advertisements. The camera records the poverty of Africa and picture down the terrify attack on 9.11. A new kind of crime--- internet or credit card cheating with its typical concealment trouble the modern people greatly.火器的运用,金属,工业革命,照明电力,无线传媒,数字电子按照科技的发展程度分别对应弊。   

All in all, it is hard to say if a technology can be simply called as good or bad. As we can't judge an effective tool if it should be promoted or banned without using. In my opinion, it is the way, which we use those technologies and the people who use them should be limited. The technology gives us a chance that we can create things by machine rather than our bare hands. It will be much wiser if we criticize the person who attempts to create the nuclear boom than inhabit the nuclear power. With the critical ethic limitation, the technical achievement should be fully promoted.

Issue 114

"Humanity has made little real progress over the past century or so. Technological innovations have taken place, but the overall condition of humanity is no better. War, violence, and poverty are still with us. Technology cannot change the condition of humanity."

Have technological innovations of the last century failed to bring about true progress for humanity, as the statement contends? Although I agree that technology cannot ultimately prevent us from harming one another, the statement fails to account for the significant positive impact that the modern-industrial and computer revolutions have had on the quality of life at least in the developed world.

I agree with the statement insofar as there is no technological solution to the enduring problems of war, poverty, and violence, for the reason that they stem from certain aspects of human nature--such as aggression and greed. Although future advances in biochemistry might enable us to "engineer away" those undesirable aspects, in the meantime it is up to our economists, diplomats, social reformers, and jurists--not our scientists and engineers--to mitigate these problems. Admittedly, many technological developments during the last century have helped reduce human suffering. Consider, for instance, technology that enables computers to map Earth's geographical features from outer space. This technology allows us to locate lands that can be cultivated for feeding malnourished people in third-world countries. And, few would disagree that humanity is the beneficiary of the myriad of 20th-Century innovations in medicine and medical technology--from prostheses and organ transplants to vaccines and lasers.

Yet, for every technological innovation, helping to reduce human suffering is another that has served primarily to add to it. For example, while some might argue that nuclear weapons serve as invaluable "peace-keepers," this argument flies in the face of the hundreds of thousands of innocent people murdered and maimed by atomic blasts. More recently, the increasing use of chemical weapons for human slaughter points out that so-called "advances" in biochemistry can amount to net losses for humanity.

Of course, such progress has not come without costs. One harmful byproduct of industrial progress is environmental pollution, and its threat to public health. Another is the alienation of assembly-line workers from their work. And, the Internet breeds information overload and steals our time and attention away from family, community, and coworkers. Nevertheless, on balance both the modern-industrial and computer revolutions have improved our standard of living and comfort level; and both constitute progress by any measure.

In sum, enduring problems such as war, poverty, and violence ultimately spring from human nature, which no technological innovation short of genetic engineering can alter. Thus the statement is correct in this respect. However, if we define "progress" more narrowly--in terms of economic standard of living and comfort level--recent technological innovations have indeed brought about clear progress for humanity.

新东方背诵 50篇

11 Archaeology
Archaeology is a source of history, not just a bumble auxiliary discipline. Archaeological data are historical documents in their own right, not mere illustrations to written texts, Just as much as any other historian, an archaeologist studies and tries to reconstitute the process that has created the human world in which we live - and us ourselves in so far as we are each creatures of our age and social environment. Archaeological data are all changes in the material world resulting from human action or, more succinctly, the fossilized results of human behavior. The sum total of these constitutes what may be called the archaeological record. This record exhibits certain peculiarities and deficiencies the consequences of which produce a rather superficial contrast between archaeological history and the more familiar kind based upon written records.

Not all human behavior fossilizes. The words I utter and you hear as vibrations in the air are certainly human changes in the material world and may be of great historical significance. Yet they leave no sort of trace in the archaeological records unless they are captured by a dictaphone or written down by a clerk. The movement of troops on the battlefield may "change the course of history," but this is equally ephemeral from the archaeologist's standpoint. What is perhaps worse, most organic materials are perishable. Everything made of wood, hide, wool, linen, grass, hair, and similar materials will decay and vanish in dust in a few years or centuries, save under very exceptional conditions. In a relatively brief period the archaeological record is reduce to mere scraps of stone, bone, glass, metal, and earthenware. Still modern archaeology, by applying appropriate techniques and comparative methods, aided by a few lucky finds from peat-bogs, deserts, and frozen soils, is able to fill up a good deal of the gap.


12 Museums
From Boston to Los Angeles, from New York City to Chicago to Dallas, museums are either planning, building, or wrapping up wholesale expansion programs. These programs already have radically altered facades and floor plans or are expected to do so in the not-too-distant future.

In New York City alone, six major institutions have spread up and out into the air space and neighborhoods around them or are preparing to do so.

The reasons for this confluence of activity are complex, but one factor is a consideration everywhere - space. With collections expanding, with the needs and functions of museums changing, empty space has become a very precious commodity.

Probably nowhere in the country is this more true than at the Philadelphia Museum of Art, which has needed additional space for decades and which received its last significant facelift ten years ago. Because of the space crunch, the Art Museum has become increasingly cautious in considering acquisitions and donations of art, in some cases passing up opportunities to strengthen its collections.

Deaccessing - or selling off - works of art has taken on new importance because of the museum's space problems. And increasingly, curators have been forced to juggle gallery space, rotating one masterpiece into public view while another is sent to storage.

Despite the clear need for additional gallery and storage space, however," the museum has no plan, no plan to break out of its envelope in the next fifteen years," according to Philadelphia Museum of Art's president.


13 Skyscrapers and Environment
In the late 1960's, many people in North America turned their attention to environmental problems, and new steel-and-glass skyscrapers were widely criticized. Ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities.

Skyscrapers are also lavish consumers, and wasters, of electric power. In one recent year, the addition of 17 million square feet of skyscraper office space in New York City raised the peak daily demand for electricity by 120, 000 kilowatts-enough to supply the entire city of Albany, New York, for a day.

Glass-walled skyscrapers can be especially wasteful. The heat loss (or gain)through a wall of half-inch plate glass is more than ten times that through a typical masonry wall filled with insulation board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.

Skyscrapers put a severe strain on a city's sanitation facilities, too. If fully occupied, the two World Trade Center towers in New York City would alone generate 2.25 million gallons of raw sewage each year-as much as a city the size of Stanford, Connecticut , which has a population of more than 109, 000.


14 A Rare Fossil Record
The preservation of embryos and juveniles is a rate occurrence in the fossil record. The tiny, delicate skeletons are usually scattered by scavengers or destroyed by weathering before they can be fossilized. Ichthyosaurs had a higher chance of being preserved than did terrestrial creatures because, as marine animals, they tended to live in environments less subject to erosion. Still, their fossilization required a suite of factors: a slow rate of decay of soft tissues, little scavenging by other animals, a lack of swift currents and waves to jumble and carry away small bones, and fairly rapid burial. Given these factors, some areas have become a treasury of well-preserved ichthyosaur fossils.

The deposits at Holzmaden, Germany, present an interesting case for analysis. The ichthyosaur remains are found in black, bituminous marine shales deposited about 190 million years ago. Over the years, thousands of specimens of marine reptiles, fish and invertebrates have been recovered from these rocks. The quality of preservation is outstanding, but what is even more impressive is the number of ichthyosaur fossils containing preserved embryos. Ichthyosaurs with embryos have been reported from 6 different levels of the shale in a small area around Holzmaden, suggesting that a specific site was used by large numbers of ichthyosaurs repeatedly over time. The embryos are quite advanced in their physical development; their paddles, for example, are already well formed. One specimen is even preserved in the birth canal. In addition, the shale contains the remains of many newborns that are between 20 and 30 inches long.

Why are there so many pregnant females and young at Holzmaden when they are so rare elsewhere? The quality of preservation is almost unmatched and quarry operations have been carried out carefully with an awareness of the value of the fossils. But these factors do not account for the interesting question of how there came to be such a concentration of pregnant ichthyosaurs in a particular place very close to their time of giving birth.


15 The Nobel Academy
For the last 82years, Sweden's Nobel Academy has decided who will receive the Nobel Prize in Literature, thereby determining who will be elevated from the great and the near great to the immortal. But today the Academy is coming under heavy criticism both from the without and from within. Critics contend that the selection of the winners often has less to do with true writing ability than with the peculiar internal politics of the Academy and of Sweden itself. According to Ingmar Bjorksten , the cultural editor for one of the country's two major newspapers, the prize continues to represent "what people call a very Swedish exercise: reflecting Swedish tastes."

The Academy has defended itself against such charges of provincialism in its selection by asserting that its physical distance from the great literary capitals of the world actually serves to protect the Academy from outside influences. This may well be true, but critics respond that this very distance may also be responsible for the Academy's inability to perceive accurately authentic trends in the literary world.

Regardless of concerns over the selection process, however, it seems that the prize will continue to survive both as an indicator of the literature that we most highly praise, and as an elusive goal that writers seek. If for no other reason, the prize will continue to be desirable for the financial rewards that accompany it; not only is the cash prize itself considerable, but it also dramatically increases sales of an author's books.


16. the war between Britain and France
In the late eighteenth century, battles raged in almost every corner of Europe, as well as in the Middle East, south Africa ,the West Indies, and Latin America. In reality, however, there was only one major war during this time, the war between Britain and France. All other battles were ancillary to this larger conflict, and were often at least partially related to its antagonist’ goals and strategies. France sought total domination of Europe . this goal was obstructed by British independence and Britain’s efforts throughout the continent to thwart Napoleon; through treaties. Britain built coalitions (not dissimilar in concept to today’s NATO) guaranteeing British participation in all major European conflicts. These two antagonists were poorly matched, insofar as they had very unequal strengths; France was predominant on land, Britain at sea. The French knew that, short of defeating the British navy, their only hope of victory was to close all the ports of Europe to British ships. Accordingly, France set out to overcome Britain by extending its military domination from Moscow t Lisbon, from Jutland to Calabria. All of this entailed tremendous risk, because France did not have the military resources to control this much territory and still protect itself and maintain order at home.

French strategists calculated that a navy of 150 ships would provide the force necessary to defeat the British navy. Such a force would give France a three-to-two advantage over Britain. This advantage was deemed necessary because of Britain’s superior sea skills and technology because of Britain’s superior sea skills and technology, and also because Britain would be fighting a defensive war, allowing it to win with fewer forces. Napoleon never lost substantial impediment to his control of Europe. As his force neared that goal, Napoleon grew increasingly impatient and began planning an immediate attack.



17.Evolution of sleep
Sleep is very ancient. In the electroencephalographic sense we share it with all the primates and almost all the other mammals and birds: it may extend back as far as the reptiles.

There is some evidence that the two types of sleep, dreaming and dreamless, depend on the life-style of the animal, and that predators are statistically much more likely to dream than prey, which are in turn much more likely to experience dreamless sleep. In dream sleep, the animal is powerfully immobilized and remarkably unresponsive to external stimuli. Dreamless sleep is much shallower, and we have all witnessed cats or dogs cocking their ears to a sound when apparently fast asleep. The fact that deep dream sleep is rare among pray today seems clearly to be a product of natural selection, and it makes sense that today, when sleep is highly evolved, the stupid animals are less frequently immobilized by deep sleep than the smart ones. But why should they sleep deeply at all? Why should a state of such deep immobilization ever have evolved?

Perhaps one useful hint about the original function of sleep is to be found in the fact that dolphins and whales and aquatic mammals in genera seem to sleep very little. There is, by and large, no place to hide in the ocean. Could it be that, rather than increasing an animal’s vulnerability, the University of Florida and Ray Meddis of London University have suggested this to be the case. It is conceivable that animals who are too stupid to be quite on their own initiative are, during periods of high risk, immobilized by the implacable arm of sleep. The point seems particularly clear for the young of predatory animals. This is an interesting notion and probably at least partly true.


18.Modern American Universities
Before the 1850’s, the United States had a number of small colleges, most of them dating from colonial days. They were small, church connected institutions whose primary concern was to shape the moral character of their students.

Throughout Europe, institutions of higher learning had developed, bearing the ancient name of university. In German university was concerned primarily with creating and spreading knowledge, not morals. Between mid-century and the end of the 1800’s, more than nine thousand young Americans, dissatisfied with their training at home, went to Germany for advanced study. Some of them return to become presidents of venerable colleges-----Harvard, Yale, Columbia---and transform them into modern universities. The new presidents broke all ties with the churches and brought in a new kind of faculty. Professors were hired for their knowledge of a subject, not because they were of the proper faith and had a strong arm for disciplining students. The new principle was that a university was to create knowledge as well as pass it on, and this called for a faculty composed of teacher-scholars. Drilling and learning by rote were replaced by the German method of lecturing, in which the professor’s own research was presented in class. Graduate training leading to the Ph.D., an ancient German degree signifying the highest level of advanced scholarly attainment, was introduced. With the establishment of the seminar system, graduate student learned to question, analyze, and conduct their own research.

At the same time, the new university greatly expanded in size and course offerings, breaking completely out of the old, constricted curriculum of mathematics, classics, rhetoric, and music. The president of Harvard pioneered the elective system, by which students were able to choose their own course of study. The notion of major fields of study emerged. The new goal was to make the university relevant to the real pursuits of the world. Paying close heed to the practical needs of society, the new universities trained men and women to work at its tasks, with engineering students being the most characteristic of the new regime. Students were also trained as economists, architects, agriculturalists, social welfare workers, and teachers.


19.children’s numerical skills
people appear to born to compute. The numerical skills of children develop so early and so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impress accuracy---one knife, one spoon, one fork, for each of the five chairs. Soon they are capable of nothing that they have placed five knives, spoons and forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and retrieved seven years later, he or she could enter a second enter a second-grade mathematics class without any serious problems of intellectual adjustment.

Of course, the truth is not so simple. This century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped-----or, as the case might be, bumped into-----concepts that adults take for quantity is unchanged as water pours from a short glass into a tall thin one. Psychologists have since demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers------the idea of a oneness,

a twoness, a threeness that applies to any class of objects and is a prerequisite for doing anything more mathematically demanding than setting a table-----is itself far from innate


20 The Historical Significance of American Revolution
The ways of history are so intricate and the motivations of human actions so complex that it is always hazardous to attempt to represent events covering a number of years, a multiplicity of persons, and distant localities as the expression of one intellectual or social movement; yet the historical process which culminated in the ascent of Thomas Jefferson to the presidency can be regarded as the outstanding example not only of the birth of a new way of life but of nationalism as a new way of life. The American Revolution represents the link between the seventeenth century, in which  modern England became conscious of itself, and the awakening of modern Europe at the end of the eighteenth century. It may seem strange that the march of history should have had to cross the Atlantic Ocean, but only  in the North American colonies could a struggle for civic liberty lead also to the foundation of a new nation. Here, in the popular rising against a “tyrannical” government, the fruits were more than the securing of a freer constitution. They included the growth of a nation born in liberty by the will of the people, not from the roots of common descent, a geographic entity, or the ambitions of king or dynasty. With the American nation, for the first time, a nation was born, not in the dim past of history but before the eyes of the whole world.

21 The Origin of Sports
When did sport begin? If sport is, in essence, play, the claim might be made that sport is much older than humankind, for , as we all have observed, the beasts play. Dogs and cats wrestle and play ball games. Fishes and birds dance. The apes have simple, pleasurable games. Frolicking infants, school children playing tag, and adult arm wrestlers are demonstrating strong, transgenerational and transspecies bonds with the universe of animals – past, present, and future. Young animals, particularly, tumble, chase, run wrestle, mock, imitate, and laugh (or so it seems) to the point of delighted exhaustion. Their play, and ours, appears to serve no other purpose than to give pleasure to the players, and apparently, to remove us temporarily from the anguish of life in earnest.

Some philosophers have claimed that our playfulness is the most noble part of our basic nature. In their generous conceptions, play harmlessly and experimentally permits us to put our creative forces, fantasy, and imagination into action. Play is release from the tedious battles against scarcity and decline which are the incessant, and inevitable, tragedies of life. This is a grand conception that excites and provokes. The holders of this view claim that the origins of our highest accomplishments ---- liturgy, literature, and law ---- can be traced to a play impulse which, paradoxically, we see most purely enjoyed by young beasts and children. Our sports, in this rather happy, nonfatalistic view of human nature, are more splendid creations of the nondatable, transspecies play impulse.


22. Collectibles
Collectibles have been a part of almost every culture since ancient times. Whereas some objects have been collected for their usefulness, others have been selected for their aesthetic beauty alone. In the United States, the kinds of collectibles currently popular range from traditional objects such as stamps, coins, rare books, and art to more recent items of interest like dolls, bottles, baseball cards, and comic books.

Interest in collectibles has increased enormously during the past decade, in part because some collectibles have demonstrated their value as investments. Especially during cycles of high inflation, investors try to purchase tangibles that will at least retain their current market values. In general, the most traditional collectibles will be sought because they have preserved their value over the years, there is an organized auction market for them, and they are most easily sold in the event that cash is needed. Some examples of the most stable collectibles are old masters, Chinese ceramics, stamps, coins, rare books, antique jewelry, silver, porcelain, art by well-known artists, autographs, and period furniture. Other items of more recent interest include old photograph records, old magazines, post cards, baseball cards, art glass, dolls, classic cars, old bottles, and comic books. These relatively new kinds of collectibles may actually appreciate faster as short-term investments, but may not hold their value as long-term investments. Once a collectible has had its initial play, it appreciates at a fairly steady rate, supported by an increasing number of enthusiastic collectors competing for the limited supply of collectibles that become increasingly more difficult to locate.


23 Ford
Although Henry Ford’s name is closely associated with the concept of mass production, he should receive equal credit for introducing labor practices as early as 1913 that would be considered advanced even by today’s standards. Safety measures were improved, and the work day was reduced to eight hours, compared with the ten-or twelve-hour day common at the time. In order to accommodate the shorter work day, the entire factory was converted from two to three shifts.

In addition, sick leaves as well as improved medical care for those injured on the job were instituted. The Ford Motor Company was one of the first factories to develop a technical school to train specialized skilled laborers and an English language school for immigrants. Some efforts were even made to hire the handicapped and provide jobs for former convicts.

The most widely acclaimed innovation was the five-dollar-a-day minimum wage that was offered in order to recruit and retain the best mechanics and to discourage the growth of labor unions. Ford explained the new wage policy in terms of efficiency and profit sharing. He also mentioned the fact that his employees would be able to purchase the automobiles that they produced – in effect creating a market for the product. In order to qualify for the minimum wage, an employee had to establish a decent home and demonstrate good personal habits, including sobriety, thriftiness, industriousness, and dependability. Although some criticism was directed at Ford for involving himself too much in the personal lives of his employees, there can be no doubt that, at a time when immigrants were being taken advantage of in frightful ways, Henry Ford was helping many people to establish themselves in America.


24.Piano
The ancestry of the piano can be traced to the early keyboard instruments of the fifteenth and sixteenth centuries --- the spinet, the dulcimer, and the virginal. In the seventeenth century the organ, the clavichord, and the harpsichord became the chief instruments of the keyboard group, a supremacy they maintained until the piano supplanted them at the end of the eighteenth century. The clavichord’s tone was metallic and never powerful; nevertheless, because of the variety of tone possible to it, many composers found the clavichord a sympathetic instrument for intimate chamber music. The harpsichord with its bright, vigorous tone was the favorite instrument for supporting the bass of the small orchestra of the period and for concert use, but the character of the tone could not be varied save by mechanical or structural devices.

The piano was perfected in the early eighteenth century by a harpsichord maker in Italy (though musicologists point out several previous instances of  the instrument). This instrument was called a piano e forte (sort and loud), to indicate its dynamic versatility; its strings were struck by a recoiling hammer with a felt-padded head. The wires were much heavier in the earlier instruments. A series of mechanical improvements continuing well into the nineteenth century, including the introduction of pedals to sustain tone or to soften it, the perfection of a metal frame, and steel wire of the finest quality, finally produced an instrument capable of myriad tonal effects from the most delicate harmonies to an almost orchestral fullness of sound, from a liquid, singing tone to a sharp, percussive brilliance.

25. Movie Music
Accustomed though we are to speaking of the films made before 1927 as “silent”, the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment; when the Lumiere films were shown at the first public film exhibition in the United States in February 1896, they were accompanied by piano improvisations on popular tunes. At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient. Within a very short time, however, the incongruity of playing lively music to a solemn film became apparent, and film pianists began to take some care in matching their pieces to the mood of the film.

As movie theaters grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain cases, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program rested entirely in the hands of the conductor or leader of the orchestra, and very often the principal qualification for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before they were to be shown(if indeed, the conductor was lucky enough to see them then), the musical arrangement was normally improvised in the greatest hurry.

To help meet this difficulty, film distributing companies started the practice of publishing suggestions for musical accompaniments. In 1909, for example, the Edison Company began issuing with their films such indications of mood as “ pleasant”, “sad”, “lively”. The suggestions became more explicit, and so emerged the musical cue sheet containing indications of mood, the titles of suitable pieces of music, and precise directions to show where one piece led into the next.

Certain films had music especially composed for them. The most famous of these early special scores was that composed and arranged for D.W Griffith’s film Birth of a Nation, which was released in 1915.

26. International Business and Cross-cultural Communication
The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts.

Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation.

In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal purveyor of information and cash.

In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator.



27. Scientific Theories
In science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.

A useful theory, in addition to explaining past observations, helps to predict events that have not as yet been observed. After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientist’s predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.

Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves are not science. As the mathematician Jules Henri Poincare said, “Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house.”

Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses.

In a way, any hypothesis is a leap into the unknown. It extends the scientist’s thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. Without hypothesis, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories.



28.Changing Roles of Public Education
One of the most important social developments that helped to make possible a shift in thinking about the role of public education was the effect of the baby boom of the 1950's and 1960's on the schools. In the 1920's, but especially in the Depression conditions of the 1930's, the United States experienced a declining birth rate --- every thousand women aged fifteen to forty-four gave birth to about 118 live children in 1920, 89.2 in 1930, 75.8 in 1936, and 80 in 1940. With the growing prosperity brought on by the Second World War and the economic boom that followed it young people married and established households earlier and began to raise larger families than had their predecessors during the Depression. Birth rates rose to 102 per thousand in 1946,106.2 in 1950, and 118 in 1955. Although economics was probably the most important determinant, it is not the only explanation for the baby boom. The increased value placed on the idea of the family also helps to explain this rise in birth rates. The baby boomers began streaming into the first grade by the mid 1940's and became a flood by 1950. The public school system suddenly found itself overtaxed. While the number of schoolchildren rose because of wartime and postwar conditions, these same conditions made the schools even less prepared to cope with the food. The wartime economy meant that few new schools were built between 1940 and 1945. Moreover, during the war and in the boom times that followed, large numbers of teachers left their profession for better-paying jobs elsewhere in the economy.

Therefore in the 1950’s and 1960’s, the baby boom hit an antiquated and inadequate school system. Consequently, the “ custodial rhetoric” of the 1930’s and early 1940’s no longer made sense that is, keeping youths aged sixteen and older out of the labor market by keeping them in school could no longer be a high priority for an institution unable to find space and staff to teach younger children aged five to sixteen. With the baby boom, the focus of educators and of laymen interested in education inevitably turned toward the lower grades and back to basic academic skills and discipline. The system no longer had much interest in offering nontraditional, new, and extra services to older youths.


29 Telecommuting
Telecommuting-- substituting the computer for the trip to the job ----has been hailed as a solution to all kinds of problems related to office work.

For workers it promises freedom from the office, less time wasted in traffic, and help with child-care conflicts. For management, telecommuting helps keep high performers on board, minimizes tardiness and absenteeism by eliminating commutes, allows periods of solitude for high-concentration tasks, and provides scheduling flexibility. In some areas, such as Southern California and Seattle, Washington, local governments are encouraging companies to start telecommuting programs in order to reduce rush-hour congestion and improve air quality.

But these benefits do not come easily. Making a telecommuting program work requires careful planning and an understanding of the differences between telecommuting realities and popular images.

Many workers are seduced by rosy illusions of life as a telecommuter. A computer programmer from New York City moves to the tranquil Adirondack Mountains and stays in contact with her office via computer. A manager comes in to his office three days a week and works at home the other two. An accountant stays home to care for her sick child; she hooks up her telephone modern connections and does office work between calls to the doctor.

These are powerful images, but they are a limited reflection of reality. Telecommuting workers soon learn that it is almost impossible to concentrate on work and care for a young child at the same time. Before a certain age, young children cannot recognize, much less respect, the necessary boundaries between work and family. Additional child support is necessary if the parent is to get any work done.

Management too must separate the myth from the reality. Although the media has paid a great deal of attention to telecommuting in most cases it is the employee’s situation, not the availability of technology that precipitates a telecommuting arrangement.

That is partly why, despite the widespread press coverage, the number of companies with work-at-home programs or policy guidelines remains small.




30 The origin of Refrigerators
By the mid-nineteenth century, the term “icebox” had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War( 1861-1865),as ice was used to refrigerate freight cars, it also came into household use. Even before 1880,half of the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.


Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.

But as early as 1803, and ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers  would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

新东方背诵 50篇 4

31 British Columbia
British Columbia is the third largest Canadian provinces, both in area and population. It is nearly 1.5 times as large as Texas, and extends 800 miles(1,280km) north from the United States border. It includes Canada’s entire west coast and the islands just off the coast.

Most of British Columbia is mountainous, with long rugged ranges running north and south. Even the coastal islands are the remains of a mountain range that existed thousands of years ago. During the last Ice Age, this range was scoured by glaciers until most of it was beneath the sea. Its peaks now show as islands scattered along the coast.

The southwestern coastal region has a humid mild marine climate. Sea winds that blow inland from the west are  warmed by a current of warm water that flows through the  Pacific Ocean. As a result, winter temperatures average above freezing and summers are mild. These warm western winds also carry moisture from the ocean.

Inland from the coast, the winds from the Pacific meet the mountain barriers of the coastal ranges and  the Rocky Mountains. As they rise to cross the mountains, the winds are cooled, and their moisture begins to fall as rain. On some of the western slopes almost 200 inches (500cm) of rain fall each year.

More than half of British Columbia is heavily forested. On mountain slopes that receive plentiful rainfall, huge Douglas firs rise in towering columns. These forest giants often grow to be as much as 300 feet(90m) tall, with diameters up to 10 feet(3m). More lumber is produced from these trees than from any other kind of tree in North America. Hemlock, red cedar, and balsam fir are among the other trees found in British Columbia.


32 Botany
Botany, the study of plants, occupies a peculiar position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insights. It is impossible to know today just what our Stone Age ancestors knew about plants, but form what we can observe of pre-industrial societies that still exist a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things even for other plants. They have always been enormously important to the welfare of people not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognize literally hundreds of plants and know many properties of each. To them, botany, as such, has no name and is probably not even recognized as a special branch of “ knowledge” at all.

Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild- and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away.


33 Plankton浮游生物.
Scattered through the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They drift about lazily with the currents, providing a basic food for many larger animals.

Plankton has been described as the equivalent of the grasses that grow on the dry land continents, and the comparison is an appropriate one. In potential food value, however, plankton far outweighs that of the land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates each year, the sea’s plankton generates more than twice as much.

Despite its enormous food potential, little effect was made until recently to farm plankton as we farm grasses on land. Now marine scientists have at last begun to study this possibility, especially as the sea’s resources loom even more important as a means of feeding an expanding world population.

No one yet has seriously suggested that “ plankton-burgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among marine scientists.

One type of plankton that seems to have great harvest possibilities is a tiny shrimp-like creature called krill. Growing to two or three inches long, krill provides the major food for the great blue whale, the largest animal to ever inhabit the Earth. Realizing that this whale may grow to 100 feet and weigh 150 tons at maturity, it is not surprising that each one devours more than one ton of krill daily.


34 Raising Oysters
In the oysters were raised in much the same way as dirt farmers raised tomatoes- by transplanting them. First, farmers selected the oyster bed, cleared the bottom of old shells and other debris, then scattered clean shells about. Next, they ”planted” fertilized oyster eggs, which within two or three weeks hatched into larvae. The larvae drifted until they attached themselves to the clean shells on the bottom. There they remained and in time grew into baby oysters called seed or spat. The spat grew larger by drawing in seawater from which they derived microscopic particles of food. Before long, farmers gathered the baby oysters, transplanted them once more into another body of water to fatten them up.

Until recently the supply of wild oysters and those crudely farmed were more than enough to satisfy people’s needs. But today the delectable seafood is no longer available in abundance. The problem has become so serious that some oyster beds have vanished entirely.

Fortunately, as far back as the early 1900’s marine biologists realized that if new measures were not taken, oysters would become extinct or at best a luxury food. So they set up well-equipped hatcheries and went to work. But they did not have the proper equipment or the skill to handle the eggs. They did not know when, what, and how to feed the larvae. And they knew little about the predators that attack and eat baby oysters by the millions. They failed, but they doggedly kept at it. Finally, in the 1940’s a significant breakthrough was made.

The marine biologists discovered that by raising the temperature of the water, they could induce oysters to spawn not only in the summer but also in the fall, winter, and spring. Later they  developed a technique for feeding the larvae and rearing them to spat. Going still further, they succeeded in breeding new strains that were resistant to diseases, grew faster and larger, and flourished in water of different salinities and temperatures. In addition, the cultivated oysters tasted better!


35.Oil Refining
An important new industry, oil refining, grew after the Civil war. Crude oil, or petroleum – a dark, thick ooze from the earth – had been known for hundreds of years, but little use had ever been made of it. In the 1850’s Samuel M. Kier, a manufacturer in western Pennsylvania, began collecting the oil from local seepages and refining it into kerosene. Refining, like smelting, is a process of removing impurities from a raw material.

Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to  get. Soon there was a large demand for kerosene. People began to search for new supplies of petroleum.

The first oil well was drilled by E.L. Drake, a retired railroad conductor. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it “ Drake’s Folly”. But when he had drilled down about 70 feet(21 meters), Drake struck oil. His well began to yield 20 barrels of crude oil a day.

News of Drake’s success brought oil prospectors to the scene. By the early 1860’s these wildcatters were drilling for “ black gold” all over western Pennsylvania. The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush.

Crude oil could be refined into many products. For some years kerosene continued to be the principal one. It was sold in grocery stores and door-to-door. In the 1880’s refiners learned how to make other petroleum products such as waxes and lubricating oils. Petroleum was not then used to make gasoline or heating oil.


36.Plate Tectonics and Sea-floor Spreading
The theory of plate tectonics describes the motions of the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere(n.[地]岩石圈)is divided into a few dozen plates of various sizes and shapes, in general the plates are in motion with respect to one another. A mid-ocean ridge is a boundary between plates where new lithospheric material is injected from below. As the plates diverge from a mid-ocean ridge they slide on a more yielding layer at the base of the lithosphere.

Since the size of the Earth is essentially constant, new lithosphere can be created at the mid-ocean ridges only if an equal amount of lithospheric material is consumed elsewhere. The site of this destruction is another kind of plate boundary: a subduction zone. There one plate dives under the edge of another and is reincorporated into the mantle. Both kinds of plate boundary are associated with fault systems, earthquakes and volcanism, but the kinds of geologic activity observed at the two boundaries are quite different.

The idea of sea-floor spreading actually preceded the theory of plate tectonics. In its original version, in the early 1960’s, it described the creation and destruction of the ocean floor, but it did not specify rigid lithospheric plates. The hypothesis was substantiated soon afterward by the discovery that periodic reversals of the Earth’s magnetic field are recorded in the oceanic crust. As magma rises under the mid-ocean ridge, ferromagnetic minerals in the magma become magnetized in the direction of the magma become magnetized in the direction of the geomagnetic field. When the magma cools and solidifies, the direction and the polarity of the field are preserved in the magnetized volcanic rock. Reversals of the field give rise to a series of magnetic stripes running parallel to the axis of the rift. The oceanic crust thus serves as a magnetic tape recording of the history of the geomagnetic field that can be dated independently; the width of the stripes indicates the rate of the sea-floor spreading.





37 Icebergs
Icebergs are among nature’s most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being ----- somewhere ------in faraway, frigid waters, amid thunderous noise and splashing turbulence, which in most cases no one hears or sees. They exist only a short time and then slowly waste away just as unnoticed.

Objects of sheerest beauty they have been called. Appearing in an endless variety of shapes, they may be dazzlingly white, or they may be glassy blue, green or purple, tinted faintly of in darker hues. They are graceful, stately, inspiring ----- in calm, sunlight seas.

But they are also called frightening and dangerous, and that they are ----  in the night, in the fog, and in storms. Even in clear weather one is wise to stay a safe distance away from them. Most of their bulk is hidden below the water, so their underwater parts may extend out far beyond the visible top. Also, they may roll over unexpectedly, churning the waters around them.

Icebergs are parts of glaciers that break off, drift into the water, float about awhile, and finally melt. Icebergs afloat today are made of snowflakes that have fallen over long ages of time. They embody snows that drifted down hundreds, or many thousands, or in some cases maybe a million years ago. The snows fell in polar regions and on cold mountains, where they melted only a little or not at all, and so collected to great depths over the years and centuries.

As each year’s snow accumulation lay on the surface, evaporation and melting caused the snowflakes slowly to lose their feathery points and become tiny grains of ice. When new snow fell on top of the old, it too turned to icy grains. So blankets of snow and ice grains mounted layer upon layer and were of such great thickness that the weight of the upper layers compressed the lower ones. With time and pressure from above, the many small ice grains joined and changed to larger crystals, and eventually the deeper crystals merged into a solid mass of ice.

Topaz is a hard, transparent mineral. It is a compound of aluminum, silica, and fluorine. Gem topaz is valuable. Jewelers call this variety of the stone “precious topaz”. The best-known precious topaz gems range in color from rich yellow to light brown or pinkish red. Topaz is one of the hardest gem minerals. In the mineral table of hardness, it has a rating of 8, which means that a knife cannot cut it, and that topaz will scratch quartz.

The golden variety of precious topaz is quite uncommon. Most of the world’s topaz is white or blue. The white and blue crystals of topaz are large, often weighing thousands of carats. For this reason, the value of topaz does not depend so much on its size as it does with diamonds and many other precious stones, where the value increases about four times with each doubling of weight. The value of a topaz is largely determined by its quality. But color is also important: blue topaz, for instance, is often irradiated to deepen and improve its color.

Blue topaz is often sold as aquamarine and a variety of brown quartz is widely sold as topaz. The quartz is much less brilliant and more plentiful than true topaz. Most of it is variety of amethyst: that heat has turned brown.

39 The Salinity of Ocean Waters
If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. In this manner the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When sea water is frozen, the dissolved materials are left behind. In this manner, sea water directly materials are left behind. In this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

40 Cohesion-tension Theory
Atmospheric pressure can support a column of water up to 10 meters high. But plants can move water much higher; the sequoia tree can pump water to its very top more than 100 meters above the ground. Until the end of the nineteenth century, the movement of water in trees and other tall plants was a mystery. Some botanists hypothesized that the living cells of plants acted as pumps. But many experiments demonstrated that the stems of plants in which all the cells are killed can still move water to appreciable heights. Other explanations for the movement of water in plants have been based on root pressure, a push on the water from the roots at the bottom of the plant. But root pressure is not nearly great enough to push water to the tops of tall trees. Furthermore, the conifers, which are among the tallest trees, have unusually low root pressures.

If water is not pumped to the top of a tall tree, and if it is not pushed to the top of a tall tree, then we may ask: how does it get there? According to the currently accepted cohesion-tension theory, water is pulled there. The pull on a rising column of water in a plant results from the evaporation of water at the top of the plant. As water is lost from the surface of the leaves, a negative pressure, or tension, is created. The evaporated water is replaced by water moving from inside the plant in unbroken columns that extend from the top of a plant to its roots. The same forces that create surface tension in any sample of water are responsible for the maintenance of these unbroken columns of water. When water is confined in tubes of very small bore, the forces of cohesion (the attraction between water molecules) are so great that the strength of a column of water compares with the strength of a steel wire of the same diameter. This cohesive strength permits columns of water to be pulled to great heights without being broken.

41.American black bears
American black bears appear in a variety of colors despite their name. In the eastern part of their range, most of these brown, red, or even yellow coats. To the north, the black bear is actually gray or white in color. Even in the same litter, both brown and black furred bears may be born.

Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell.

Like all bears, the black bear is timid, clumsy, and rarely dangerous , but if attacked, most can climb trees and cover ground at great speeds. When angry or frightened, it is a formidable enemy.

Black bears feed on leaves, herbs. Fruit, berries, insects, fish, and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike squirrels, woodchucks, and many other woodland animals, bears do not actually hibernate. Although the bear does not during the winter moths, sustaining itself from body fat, its temperature remains almost normal, and it breathes regularly four or five times per minute.

Most black bears live alone, except during mating season. They prefer to live in caves, hollow logs, or dense thickets. A little of one to four cubs is born in January or February after a gestation period of six to nine months, and they remain with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild , and even longer in game preserves set aside for them.


42.Coal-fired power plants
The invention of the incandescent light bulb by Thomas A. Edison in 1879 created a demand for a cheap, readily available fuel with which to generate large amounts of electric power. Coal seemed to fit the bill, and it fueled the earliest power stations. (which were set up at the end of the nineteenth century by Edison himself). As more power plants were constructed throughout the country, the reliance on coal increased throughout the country, the reliance on coal increased. Since the First World War, coal-fired power plants had a combined in the United States each year. In 1986 such plants had a combined generating capacity of 289,000 megawatts and consumed 83 percent of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty in the future growth of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty in the future growth of nuclear power and in the supply of oil and natural gas, coal-fired power plants could well provide up to 70 percent of the electric power in the United States by the end of the century.

Yet, in spite of the fact that coal has long been a source of electricity and may remain on for many years(coal represents about 80 percent of United States fossil-fuel reserves), it has actually never been the most desirable fossil fuel for power plants. Coal contains less energy per unit of weight than weight than natural gas or oil; it is difficult to transport, and it is associated with a host of environmental issues, among them acid rain. Since the late 1960’s problems of emission control and waste disposal have sharply reduced the appeal of coal-fired power plants. The cost of ameliorating these environment problems along with the rising cost of building a facility as large and complex as a coal-fired power plant, have also made such plants less attractive from a purely economic perspective.

Changes in the technological base of coal-fired power plants could restore their attractiveness, however. Whereas some of these changes are intended mainly to increase the productivity of existing plants, completely new technologies for burning coal cleanly are also being developed.


43.Statistics
There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of government units (states and statistics come from the same Latin root status) and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering, and the taking of censuses—all of which led to modern descriptive statistics. From the influence of the father came modern inferential statistics, which is based squarely on theories of probability.

Describing collections involves tabulating, depicting and describing collections of data. These data may be quantitative such as measures of height, intelligence or grade level------variables that are characterized by an underlying continuum---or the data may represent qualitative variables, such as sex, college major or personality type. Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is a tool for describing or summarizing or reducing to comprehensible form the properties of an otherwise unwieldy mass of data.

Inferential statistics is a formalized body of methods for solving another class of problems that present great of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated for flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child: the proportion for the sample of as few as 100 children. Thus , the purpose of inferential statistics is to predict or estimate characteristics of a population from a knowledge of the characteristics of only a sample of the population.


44.Obtaining Fresh water from icebergs
The concept of obtaining fresh water from icebergs that are towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food.

Glaciers are a possible source of fresh water that has been overlooked until recently. Three-quarters of the Earth’s fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica.

Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes, rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. To corral them and steer them to parts of the world where they are needed would not be too difficult.

The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalinization, or removing salt from water.


45.The source of Energy
A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun’s very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and in doing so, release some of the energy that is stored in the nuclei of atoms. The output of light and heat of the Sun requires that some 600 million tons of hydrogen be converted into helium in the Sun every second. This the Sun has been doing for several thousands of millions of year.

The nuclear energy is released at the Sun’s center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun to be reemitted at slightly longer wavelengths. This radiation , in its turn is absorbed and reemitted. As the energy filters through the layers of the solar interior, it passes through the X-ray part of the spectrum eventually becoming light. At this stage, it has reached what we call the solar surface, and can escape into space without being absorbed further by solar atoms. A very small fraction of the Sun’s light and heat is emitted in such directions that after passing unhindered through interplanetary space, it hits the Earth.


46.Vision
Human vision like that of other primates has evolved in an arboreal environment. In the dense complex world of a tropical forest, it is more important to see well that to develop an acute sense of smell. In the course of evolution members of the primate line have acquired large eyes while the snout has shrunk to give the eye an unimpeded view. Of mammals only humans and some primates enjoy color vision. The red flag is black to the bull. Horses live in a monochrome world .light visible to human eyes however occupies only a very narrow band in the whole electromagnetic spectrum. Ultraviolet rays are invisible to humans though ants and honeybees are sensitive to them. Humans though ants and honeybees are sensitive to them. Humans have no direct perception of infrared rays unlike the rattlesnake which has receptors tuned into wavelengths longer than 0.7 micron. The world would look eerily different if human eyes were sensitive to infrared radiation. Then instead of the darkness of night, we would be able to move easily in a strange shadowless world where objects glowed with varying degrees of intensity. But human eyes excel in other ways. They are in fact remarkably discerning in color gradation. The color sensitivity of normal human vision is rarely surpassed even by sophisticated technical devices.





47 Folk Cultures
A folk culture is a small isolated, cohesive, conservative, nearly self-sufficient group that is homogeneous in custom and race with a strong family or clan structure and highly developed rituals. Order is maintained through sanctions based in the religion or family and interpersonal. Relationships are strong. Tradition is paramount, and change comes infrequently and slowly. There is relatively little division of labor into specialized duties. Rather, each person is expected to perform a great variety of tasks, though duties may differ between the sexes. Most goods are handmade and subsistence economy prevails. Individualism is weakly developed in folk cultures as are social classes. Unaltered folk cultures no longer exist in industrialized countries such as the United States and Canada. Perhaps the nearest modern equivalent in Anglo America is the Amish, a German American farming sect that largely renounces the products and labor saving devices of

the industrial age. In Amish areas, horse drawn buggies still serve as a local transportation device and the faithful are not permitted to own automobiles. The Amish’s central religious concept of Demut  “humility”, clearly reflects the weakness of individualism and social class so typical of folk cultures and there is a corresponding strength of Amish group identity. Rarely do the Amish marry outside their sect. The religion, a variety of the Mennonite faith, provides the principal mechanism for maintaining order.

By contrast a popular culture is a large heterogeneous group often highly individualistic and a pronounced many specialized professions. Secular institutions of control such as the police and army take the place of religion and family in maintaining order, and a money-based economy prevails. Because of these contrasts, “popular” may be viewed as clearly different from “folk”. The popular is replacing the folk in industrialized countries and in many developing nations. Folk-made objects give way to their popular equivalent, usually because the popular item is more quickly or cheaply produced, is easier or time saving to use or leads more prestige to the owner.


48 Bacteria
Bacteria are extremely small living things. While we measure our own sizes in inches or centimeters, bacterial size is measured in microns. One micron is a thousandth of a millimeter: a pinhead is about a millimeter across. Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron in diameter. Thus if you enlarged a rounded bacterium a thousand times, it would be just about the size of a pinhead. An adult human magnified by the same amount would be over a mile(1.6 kilometer) tall.

Even with an ordinary microscope, you must look closely to see bacteria. Using a magnification of 100 times, one finds that bacteria are barely visible as tiny rods or dots. One cannot make out anything of their structure. Using special stains, one can see that some bacteria have attached to them wavy-looking “hairs” called flagella. Others have only one flagellum. The flagella rotate, pushing the bacteria through the water. Many bacteria lack flagella and cannot move about by their own power, while others can glide along over surfaces by some little-understood mechanism.

From the bacteria point of view, the world is a very different place from what it is to humans. To a bacterium water is as thick as molasses is to us. Bacteria are so small that they are influenced by the movements of the chemical molecules around them. Bacteria under the microscope, even those with no flagella, often bounce about in the water. This is because they collide with the watery molecules and are pushed this way and that. Molecules move so rapidly that within a tenth of a second the molecules around a bacteria have all been replaced by new ones; even bacteria without flagella are thus constantly exposed to a changing environment.


49 Sleep
Sleet is part of a person’s daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you fist drift off into slumber, your eyes will roll about a bit, you temperature will drop slightly, your muscles will relax, and your breathing well slow and become quite regular. Your brain waves slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep. slower your brain waves will be. Then about 40to 69 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.

You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will slip gently back from stage 1 to stage 4 sleep----only to rise once again to the surface of near consciousness some 80 minutes later.


50. Cells and Temperature
Cells cannot remain alive outside certain limits of temperature and much narrower limits mark the boundaries of effective functioning. Enzyme systems of mammals and birds are most efficient only within a narrow range around 37C;a departure of a few degrees from this value seriously impairs their functioning. Even though cells can survive wider fluctuations the integrated actions of bodily systems are impaired. Other animals have a wider tolerance for changes of bodily temperature.

For centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperature. Ways of characterizing the difference have become more accurate and meaningful over time, but popular terminology still reflects the old division into “warm-blooded” and “cold-blooded” species; warm-blooded included mammals and birds whereas all other creatures were considered cold-blooded. As more species were studied, it became evident that this classification was inadequate. A fence lizard or a desert iguana—each cold-blooded----usually has a body temperature only a degree or two below that of humans and so is not cold. Therefore the next distinction was made between animals that maintain a constant body temperature, called home0therms, and those whose body temperature varies with their environments, called poikilotherms. But this classification also proved inadequate, because among mammals there are many that vary their body temperatures during hibernation. Furthermore, many invertebrates that live in the depths of the ocean never experience change in the depths of the ocean never experience change in the chill of the deep water, and their body temperatures remain constant.

Argument写作快速入门

作者:猴哥

来源:满分网



第一节 Argument 写作特点

Argument主要是要找到原文论断的逻辑错误(漏洞),然后,通过说出其它可能性,来攻击这些逻辑漏洞。

典型的论点:A地区(物种、人物)做了什么事情,得出一个结果。B地区(物种、人物)如果也这样做,也可以得出这个结果。

Argument要求找到逻辑漏洞后,还要进行有根据的论证。



第二节 Argument模板

第一段:1、归纳论点2、说明论点有问题。3、准备发起进攻

第二段:攻击论据(论据本身不成立)A有这样的结果,不一定是这个事情造成的。(1、其它原因 2、因果倒置 3、原因的真实性)

第三段攻击论证(类比不成立)A和B不同,A发生,B不一定可以发生。(范围不同、作用程度不同、时间不同、主客观不同:人的主观能力、因果倒置、事物与外界联系、不是说的一个事、是否能类比、会不会发生化学反应而改变、偷换概念、饱和度、绝对数量和相对数量、参照物不同、有其他的改变、还需要其他的条件限制或起作用、量够不够、程度)B有自己的特点。

第四段 完美让步B这样做,似乎是合理的,但是,通过论证,不是这样。B在做出决定前,应该好好考虑一下其它的情况。



第三节 Argument主题阅读式备考法范例

Six months ago the region of Forestville increased the speed limit for vehicles traveling on the region's highways by ten miles per hour.  Since that change took effect, the number of automobile accidents in that region has increased by 15 percent.  But the speed limit in Elmsford, a region neighboring Forestville, remained unchanged, and automobile accidents declined slightly during the same six-month period.  Therefore, if the citizens of Forestville want to reduce the number of automobile accidents on the region's highways, they should campaign to reduce Forestville's speed limit to what it was before the increase.
翻译:6个月前,Forestville地区提高了本地区公路上的最高时速限制,比原先提高了10公里。由于这个变化的影响,本地区车祸的数量提高了15%。但是,Elmsford地区(和Forestville地区相邻)并没有改变最高时速限制,它的车祸数量在同样的6个月里,反而有少量的减少。因此,如果Forestville市民想要减少公路上的车祸数量,他们应该想办法将本地区的最高时速限制减少到改变前的状态。



分析题目:
1、  找原题逻辑结构关系
论据:F地区提高最高时速限制10公里 ———〉车祸发生率增加15%     E地区(和F相邻)没有提高———〉车祸发生率没有增加
结论:F地区如果想要减少车祸,就要恢复到原来的最高时速限制。

第一段,1、说明论点有问题。2、归纳论点,准备发起进攻
The Argument is well-presented, but not thoroughly well-reasoned.  By making a comparison of the region of Forestville, the town with the higher speed limit and therefore automobile accidents, with the region of Elmsford, an area of a lower speed limit and subsequently fewer accidents, the Argument for reducing Forestville's speed limits in order to decrease accidents seems logical.
阅读式作文备考:
第一意群,The Argument is well-presented, but not thoroughly well-reasoned.(常用开头句型,记住)。这个论证说的不错,但是,理由不是完全充分。
第二意群,By making a comparison of the region of Forestville, the town with the higher speed limit and therefore automobile accidents, with the region of Elmsford, an area of a lower speed limit and subsequently fewer accidents, the Argument for reducing Forestville's speed limits in order to decrease accidents seems logical. 常用结构,将题目中的主要论点归纳出来。



第二段:第一轮攻击
攻击点:可能有其他原因,造成提高限速后车祸的增加。(不一定是限速引起的)(本段主题句)
论证结构:总——分——总  
However, the citizens of Forestville are failing to consider other possible alternatives to the increasing car accidents after the raise in speed limit. Such alternatives may include the fact that there are less reliable cars traveling the roads in Forestville, or that the age bracket of those in Elmsford may be more conducive to driving safely. It is possible that there are more younger, inexperienced, or more elderly, unsafe drivers in Forestville than there are in Elmsford.  In addition, the citizens have failed to consider the geographical and physical terrain of the two different areas.  Perhaps Forestville's highway is in an area of more dangerous curves, sharp turns, or has many intersections or merging points where accidents are more likely to occur.  It appears reasonable, therefore, for the citizens to focus on these trouble spots than to reduce the speed in the entire area.  Elmsford may be an area of easier driving conditions where accidents are less likely to occur regardless of the speed limit.
第一意群:However, the citizens of Forestville are failing to consider other possible alternatives to the increasing car accidents after the raise in speed limit.(找他因,猴哥逻辑单题无忧中,常用的方法)可能有其他原因,造成提高限速后车祸的增加。(不一定是限速引起的)(本段中心句)
句型收获:However, the citizens of Forestville are failing to consider other possible alternatives to the increasing car accidents after the raise in speed limit.

第二意群:Such alternatives may include the fact that there are less reliable cars traveling the roads in Forestville, or that the age bracket of those in Elmsford may be more conducive to driving safely.  It is possible that there are more younger, inexperienced, or more elderly, unsafe drivers in Forestville than there are in Elmsford.  In addition, the citizens have failed to consider the geographical and physical terrain of the two different areas.  Perhaps Forestville's highway is in an area of more dangerous curves, sharp turns, or has many intersections or merging points where accidents are more likely to occur.
有可能是因为F地区比E地区有更多的老弱和不熟练的驾车者;而且,人们可能忽略了两地地形地貌的差别;
(解释上一个意群,也就是本段中心句。这种首句题出本段论点,然后,展开解释的写作方法,实用简单,建议多使用。阅卷人最喜欢这样的句子结构,一目了然,很快就可以明白你要说什么)
(这种结构,在一段里面也可以用,不然,这么长的作文,如何写出来。)比如:(一个分观点)In addition, the citizens have failed to consider the geographical and physical terrain of the two different areas.
(将分观点详细说,举例) Perhaps Forestville's highway is in an area of more dangerous curves, sharp turns, or has many intersections or merging points where accidents are more likely to occur.
句型收获:It is possible that there are more younger, inexperienced, or more elderly, unsafe drivers in Forestville than there are in Elmsford.

第三意群:It appears reasonable, therefore, for the citizens to focus on these trouble spots than to reduce the speed in the entire area.  Elmsford may be an area of easier driving conditions where accidents are less likely to occur regardless of the speed limit.
因此,人们应该更加关注以上的问题,而不是减少限速。E地区可能是一个行车条件比较好的地区,时速限制对它的影响不大。(总结,对上面的分论的总结。总-分-总,是个分段的基本结构)
句型收获:It appears reasonable, therefore, for the citizens to focus on these trouble spots than to reduce the speed in the entire area.

至此,第一轮攻击完成。
攻击点:可能有其他原因,造成提高限速后车祸的增加。(不一定是限速引起的)(本段主题句)
论证结构:总——分——总  


第三段:第二轮攻击
攻击点:
1、6个月的时间,并不具有代表性。(以部分时间内出现的问题为依据,认定整个过程都会是这样。)
2、人口统计学攻击 (有可能,E地区的人不用行车很远去上班,甚至不用上班;现在F地区的人口,是否比6个月前多?如果多,有可能是因为人口多了,导致F地区路上的车辆多了而造成事故增加,而不是由于提高限速。)
3、危险的时间是否外出的情况在不同地区的不同(也许F地区的人习惯在清晨、黎明等不安全的时间驾车外出。而E地区的人不用这样做。)
论证结构:分——分——分(三个分论点)

A six-month period is not a particularly long time frame for the citizens to determine that speed limit has influenced the number of automobile accidents in the area.  It is mentioned in the Argument that Elmsford accidents decreased during the time period.  This may have been a time, such as during harsh weather conditions, when less people were driving on the road and therefore the number of accidents decreased.  However, Forestville citizens, perhaps coerced by employment or other requirements, were unable to avoid driving on the roads.  Again, the demographics of the population are important.  It is possible that Elmsford citizens do not have to travel far from work or work from their home, or do not work at all.  Are there more people in Forestville than there were sic months ago?  If so, there may be an increased number of accidents due to more automobiles on the road, and not due to the increased speed limits.  Also in reference to the activities of the population, it is possible that Forestville inhabitants were traveling during less safe times of the day, such as early in the morning, or during twilight.  Work or family habits may have encouraged citizens to drive during this time when Elmsford residents may not have been forced to do so.

第一意群:A six-month period is not a particularly long time frame for the citizens to determine that speed limit has influenced the number of automobile accidents in the area. It is mentioned in the Argument that Elmsford accidents decreased during the time period.

This may have been a time, such as during harsh weather conditions, when less people were driving on the road and therefore the number of accidents decreased.  However, Forestville citizens, perhaps coerced by employment or other requirements, were unable to avoid driving on the roads.

在6个月的时间进行判断,提高限速后,车祸的发生数量,时间太短。这6个月,可能具有一个比较糟糕的天气情况,人们驾车外出减少,因此车祸减少(E地区的情况),但是,F地区,可能因为工作或者其他原因,被迫驾车外出。(因为天气不好,所以F地区车祸增加,而此时刚好提高限速,大家都以为是提高限速惹的祸)
句型收获:
A six-month period is not a particularly long time frame for the citizens to determine…… (时间攻击中,经常使用)


第二意群:Again, the demographics of the population are important.  It is possible that Elmsford citizens do not have to travel far from work or work from their home, or do not work at all.  Are there more people in Forestville than there were sic months ago?  If so, there may be an increased number of accidents due to more automobiles on the road, and not due to the increased speed limits.
人口统计学也很关键,有可能,E地区的人不用行车很远去上班,甚至不用上班;现在F地区的人口,是否比6个月前多?如果多,有可能是因为人口多了,导致F地区路上的车辆多了而造成事故增加,而不是由于提高限速。
句型收获:
Are there more people in Forestville than there were sic months ago?  If so, there may be  疑问句的形式,句型多变。


第三意群:Also in reference to the activities of the population, it is possible that Forestville inhabitants were traveling during less safe times of the day, such as early in the morning, or during twilight.  Work or family habits may have encouraged citizens to drive during this time when Elmsford residents may not have been forced to do so.
参考人们一天的活动,也许F地区的人习惯在清晨、黎明等不安全的时间驾车外出。而E地区的人不用这样做。(危险的时间是否外出的情况在不同地区的不同)

第二阶段攻击结束
攻击点:
1、6个月的时间,并不具有代表性。(以部分时间内出现的问题为依据,认定整个过程都会是这样。)
2、人口统计学攻击 (有可能,E地区的人不用行车很远去上班,甚至不用上班;现在F地区的人口,是否比6个月前多?如果多,有可能是因为人口多了,导致F地区路上的车辆多了而造成事故增加,而不是由于提高限速。)
3、危险的时间是否外出的情况在不同地区的不同(也许F地区的人习惯在清晨、黎明等不安全的时间驾车外出。而E地区的人不用这样做。)
论证结构:分——分——分(三个分论点)

第四段:总论

Overall, the reasoning behind decreasing Forestville's speed limit back to its original seems logical as presented above since the citizens are acting in their own best interests and want to protect their safety.  However, before any final decisions are made about the reduction in speed limit, the citizens and officials of Forestville should evaluate all possible alternatives and causes for the increased number of accidents over the six-month period as compared to Elmsford.

第一意群:Overall, the reasoning behind decreasing Forestville's speed limit back to its original seems logical as presented above since the citizens are acting in their own best interests and want to protect their safety.
总之,论题中的关于降低F地区的限速似乎是合理的,因为市民们是出于他们的利益并且想要保证他们的安全。(让步,说论题似乎合理)


第二意群:However, before any final decisions are made about the reduction in speed limit, the citizens and officials of Forestville should evaluate all possible alternatives and causes for the increased number of accidents over the six-month period as compared to Elmsford.
但是,在做出最后的决定之前,F地区的市民和政府都应该考虑到所有其它的可能。这最后一段,一定要背下。几乎所有的Argument论题,都可以用这种方式结尾。你的论点有道理,但是,在做决定之前,要仔细考虑各种情况。

句型收获:Overall, the reasoning behind decreasing Forestville's speed limit back to its original seems logical as presented above since the citizens are acting in their own best interests and want to protect their safety.  However, before any final decisions are made about the reduction in speed limit, the citizens and officials of Forestville should evaluate all possible alternatives and causes for the increased number of accidents over the six-month period as compared to Elmsford.
  

最后总结

从三个方面总结:
1、文章内容
a)主要是论题的分析,b)找逻辑漏洞要“准”,c)攻击逻辑漏洞要“狠”、“准”、“全”
题目分析:
论据:F地区提高最高时速限制 10公里———〉车祸发生率增加15%       E地区(和F相邻)没有提高———〉车祸发生率没有增加
结论:F地区如果想要减少车祸,就要恢复到原来的最高时速限制。
逻辑漏洞:以偏概全(地理位置上、时间上、人口统计学上的不同)  
攻击点:
1、有可能是因为F地区比E地区有更多的老弱和不熟练的驾车者;而且,人们可能忽略了两地地形地貌的差别;
2、6个月的时间,并不具有代表性。(以部分时间内出现的问题为依据,认定整个过程都会是这样。)
3、人口统计学攻击 (有可能,E地区的人不用行车很远去上班,甚至不用上班;现在F地区的人口,是否比6个月前多?如果多,有可能是因为人口多了,导致F地区路上的车辆多了而造成事故增加,而不是由于提高限速。)
4、危险的时间是否外出的情况在不同地区的不同(也许F地区的人习惯在清晨、黎明等不安全的时间驾车外出。而E地区的人不用这样做。)
2、文章结构
总——分——分——总
第一段,1、说明论点有问题。2、归纳论点,准备发起进攻
第二段:第一轮攻击
第三段:第二轮攻击
第四段:总结
3、文章文采
句型收获:
However, the citizens of Forestville are failing to consider other possible alternatives to the increasing car accidents after the raise in speed limit.

It is possible that there are more younger, inexperienced, or more elderly, unsafe drivers in Forestville than there are in Elmsford.

It appears reasonable, therefore, for the citizens to focus on these trouble spots than to reduce the speed in the entire area.

A six-month period is not a particularly long time frame for the citizens to determine…… (时间攻击中,经常使用)

Are there more people in Forestville than there were sic months ago?  If so, there may be  疑问句的形式,句型多变。

Overall, the reasoning behind decreasing Forestville's speed limit back to its original seems logical as presented above since the citizens are acting in their own best interests and want to protect their safety.  However, before any final decisions are made about the reduction in speed limit, the citizens and officials of Forestville should evaluate all possible alternatives and causes for the increased number of accidents over the six-month period as compared to Elmsford.(结尾的经典句型)


分析ets的评价,你会发现,他们也是从以上三个方面分析的:
This outstanding essay begins by noting that the Argument "seems logical."  It then proceeds to discuss possible alternative explanations for the increase in car accidents and provides an impressively full analysis.  Alternatives mentioned are that

-- the two regions might have drivers of different ages and experience;
-- Forestville's topography, geography, cars, and/or roads might contribute to accidents;
-- six months might be an insufficient amount of time for determining that the speed limit is linked to the accident rate;
-- demographics might play a role in auto accidents;
-- population and auto density should be considered; and
-- the times of day when drivers in the two regions travel might be relevant.

The points are cogently developed and are linked in such a way as to create a logically organized essay.  Transitions together with interior connections create a smoothly integrated presentation.  For the most part, the writer uses language correctly and well and provides excellent variety in syntax.  The minor flaws (e.g., using "less" instead of "fewer") do not detract from the overall high quality of the critique.  This is an impressive 6 paper.

Argument最简化大纲

来源:太傻网
一.开头部分
1.  In this Argument, the arguer concludes that…
2.  To substantiate the conclusion, the arguer points out that…
3.  In addition, the arguer assumes that / reasons that / cites the example of / cites the result of a recent study that…  
4.  A careful examination of this Argument would reveal how groundless it is.

二.论证驳斥部分
First of all, the Argument is based on a false analogy. /
The arguer simply assumes that… but he does not provide any evidence that … are indeed comparable. /
As we know, … differ conspicuously. /
It is true that both… but even here exist fundamental differences:… /
Therefore, even though…proved effective in doing… there is no guarantee that it will work just as well for…//
As a result, A and B do not establish a warranted analogy. So we cannot safely assume that (两者无法比)

** The author unfairly assumes that A bears some relation to B. /
However, the author provides no evidence to support that this is the case, nor does the author establish a causal relationship between A and B. /
It is highly possible that other factors might contribute to the B/change/progress. /
For example, … It is also likely B just resulted from … /
Lacking evidence that links A to B, it is presumptuous to suggest that A was responsible for B. (无法建立必然的因果关系)

** The evidence the author provides is insufficient to support the conclusion drawn from it. /
One example is rarely sufficient to establish a general conclusion. /
Based on a specific example of… , it is logically unsounded to make suggestion for all… /
In fact, in face of such limited evidence, it is fallacious to draw any conclusion at all. /
Unless it can be shown that … is representative of all…, the conclusion that… is completely unwarranted. (单个事例不能说明整体问题)

** By concluding that sb must do A or must do B, the author commits a fallacy of “false dilemma”. /
The author assumes that A and B are the only available solutions to the problem. /
However, it is possible that other factors might also contribute to the problem. For example,… /
If so, just doing A and B would not solve the problem. (还有其他原因)

In addition, the arguer commits a fallacy of hasty generalization. /
Even if… , which is, of course, an unwarranted assumption, it does not follow that… /
It is highly possible that other factors may have contributed to B… / For instance,… /
Besides, the arguer does not provide any solid information concerning… /
Unless… , which is unknown from this Argument, there is no guarantee that… //
Without ruling out these and other possible factors that give rise to B, the author cannot confidently conclude that…(结论得出过早,考虑不周到 )

** The arguer assumes that just because one event follows another, the second event has been caused by the first. /
However, no evidence is provided to support that this is the case. /
The mere fact that A occurs before B does not necessarily establish a causal relationship between A and B. /
It is highly possible that other factors might also bring about these same results. / For instance,… In addition,… /
Without ruling out these and other possible factors that give rise to B, the author cannot confidently conclude that…

** The recommendation depends on the assumption that no alternative means of doing sth are available. /
However, the arguer fails to offer any evidence to substantiate this crucial assumption. It is highly possible that means other than this would better solve the problem. /
Without considering and ruling out these and other alternative means of doing sth, the author cannot confidently conclude that…

** The arguer assumes the characteristics of a group apply to every member of that group. /
The conclusion that… is based on the assumption that … /
However, there is no guarantee that this is the case, nor does the author provide any evidence to substantiate this assumption. It is very likely that… /
Lacking such evidence the author cannot draw any firm conclusion. (整体规律不一定适用于个人)

** It is assumed without justification that background conditions have remained the same at different times / conditions. /
The arguer unfairly infer from… in the past that… /
However, he/she fails to offer any evidence to substantiate this inference. It is very likely that…, or that… /
Any of these scenarios, if true, would serve to undermine the claim that… (从过去不能推知现在和将来)

Finally, the arguer provides no assurances that the survey on which the Argument depends is statistically reliable. /
Lacking information about the number of … surveyed and the number of respondents, it is impossible to assess the validity of the results. /
For example, if… were surveyed but only… responded, the conclusion that… would be highly suspected. /
Another problem is the representativeness of the respondents. Were they representative of all the…? Were… chosen for the survey chosen randomly or did they volunteer for the survey?… /
Lacking such evidence the author cannot draw any firm conclusion based on the study.



三.结尾部分
1.  In summary, this Argument is not persuasive as it stands.
2.  To make it more convincing, the arguer would have to provide more evidence concerning… / provide evidence to rule out other possible causes of…
3.  To better evaluate the Argument, we would need more information regarding…

Argument逻辑错误分类

来源:太傻网
庄子整理版


1. 假性因果-
Post Hoc (Post Hoc Ergo Propter Hoc, False Cause, Questionable Cause,
Confusing Coincidental Relationships With Causes)
A Post Hoc is a fallacy with the following form:
A occurs before B. Therefore A is the cause of B.

2. Cum hoc ergo propter hoc (Confusing Cause and Effect)
Confusing Cause and Effect is a fallacy that has the following general form:
A and B regularly occur together. Therefore A is the cause of B.

辨析:
In the case of a Post Hoc fallacy (http://www.nizkor.org/features/fallacies/post-hoc.html), the error is that a person is accepting that A is the cause of B simply because A occurs before B. In the case of the Fallacy of Ignoring a Common Cause
(http://www.nizkor.org/features/fall...mmon-cause.html) A is taken to be the cause of B when there is, in fact, a third factor that is the cause of both A and B.


3. 错误类比-Weak Analogy (False Analogy / Faulty Analogy / Questionable Analogy)
Form:
A is like B.  B has property P. Therefore, A has property P.
(Where the analogy between A and B is weak.)
值得参考的网站:www.fallacyfiles.org

4. 调查研究中样本无代表性,非随机样本,偏性样本-Unrepresentative Sample (Biased Sample)
This is a fallacy affecting statistical inferences, which are arguments of the following form:
N% of sample S has characteristic C. Therefore, N% of population P has characteristic C. (Where sample S is a subset of set P, the population.)

5. 草率结论-Hasty Generalization
This is the fallacy of generalizing about a population based upon a sample that is too small to be representative. If the population is heterogeneous, then the sample needs to be large enough to represent the population's variability. With a completely homogeneous population, a sample of one is sufficiently large, so it is impossible to put an absolute lower limit on sample size. Rather, sample size depends directly upon the variability of the population: the more heterogeneous a population, the larger the sample required. For instance, people tend to be quite variable in their political opinions, so that public opinion polls need fairly large samples to be accurate.

6. Affirming a Disjunct (选言枝) (Fallacy of Propositional Logic)
Form:
p or q.  p.  Therefore, not-q.

7. 分歧-Bifurcation (false dilemma)

--------------------------------------------------------------------------------

魏震整理版



1. Loose generalizations
Drawing conclusions about groups of people on the basis of stereotypes (陈词滥调).
Example: French people are more romantic.

2. Hasty generalizations -草率结论
Arriving at a conclusion without enough evidence.
Example: Asian-American students are better in math.

3. Circular Reasoning
Restating in different words what has already been stated.
Example: Dieting is hard because it requires consuming fewer calories. ?

4. Single cause-effect -假性因果
Claiming that only one event caused another when there may be no real connection.
Example: When I sat down at the computer it stopped working, so I must have done something wrong.

5. Slippery Slope ?
Assumes a chain of cause-effect relationships with very suspect connections.
Example: Because I failed my exam, my parents were mad, I lost my wallet, my car wouldn't start, and I got fired.

6. Non Sequitur -<拉>[逻]不合逻辑的推论,不根据前提推导的推论
The first part of the idea does not relate to the other.
Example: I did well in school because I always wore nice clothes.

7. Either/Or -Affirming a Disjunct (选言枝) (Fallacy of Propositional Logic)
Suggesting only two alternatives when the issue may be much more complex.
Example: America--love it or leave it!

8. False Authority -迷信权威,偶像崇拜
Draws attention away from the evidence and leans on the popularity of someone who may have little knowledge of the issue or product.
Example: Kathie Lee Gifford, a popular TV celebrity, says that cruises are wonderful, so they must be.

9. Ad Hominem -从个人偏好出发,非逻辑或理性的
Attacking the person instead of the ideas. -个人人身攻击
Example: Don't vote for Jerry Brown; he's a left-wing fanatic, a throwback to the 60s who meditates and eats health foods.

10. Bandwagon Thinking -流行思想,时髦想法
Claiming that most people agree so it must be right.
Example: I wouldn't have cheated on my income taxes, but everyone else does, so why shouldn't I? ?

11. Stacking the deck -暗中布局,作弊
Giving a slanted view of the issue by focusing only on one side. -只关注一面,而给出一个歪曲的观点
Example: I deserve to get an A in the class because I like the teacher, work hard, and attend class.

12. Appeal to Emotion -以情欺人
Exploiting the audience's feeling in order to get them on your side.
Example: I believe I deserve a scholarship because I am an orphan who grew up in a dysfunctional foster family.

13. Ignoring the question -忽略问题(的症结所在)
Changing the topic before it is really considered -偷换概念(命题)
Example: The criminal won't say where he was on the night of the crime, but he does remember being teased relentlessly as a child.

14. Trivial objections -斤斤计较
Can be similar to ad hominem in that it focuses on things unimportant to the issue at hand.
Example: I think Ross Perot would make a terrible president. His ears are huge.

模板之8大逻辑错误

1.A groundless survey/study
The validity of the survey is open to doubt.
The survey lacks representatives...
There is no specific information about the survey...
Without knowing how the survey was done, how it represents the public option
Who conducted the survey? who responded? how the pool was conducted?
The opinion lacks representatives of overall attitudes based on which we can make any general judgment about the conclusion....
In absence of specific information about the survey, it’s impossible for us to evaluate the argument.

2. Oversiplification
The arguer commits a fallacy of oversimplification.
There are several major factors contribute to the XXX other than YYY, such as/for instance ZZZ, all of which are ignored by the arguer.
As we know, XXX depends on many factors, such as ZZZ, which are unknown from the argument.
The arguer fails to establish a causal relationship between XXX and YYY.
For example, YYY may also help explain XXX.
Factors such as AA and BB both have some bearing on XXX.
Actually, the recommendation that YYYY as the only way to XXX most likely turn out to be ineffective and somewhat misleading.

3.A false analogy
The argument is based on a false analogy.
Even though there are some points of comparison between XX and YY, there are dissimilarity as well.
But the problem is that the two situation are not similar enough to justify the analogical deduction.
As we know, the struction, system, operation are conspicuously different.
It’s a incomplete and selective comparison.
Even though XX is proved effective in YYY, there is no guarantee that it will just work as well in ZZZ.

4.A gratuitous assumption
The argument is based on a gratuitous assumption that ####,which is, of course unwarranted.
The arguer fails to convince us that....

5.A false dilemma
The arguer unfairly assumes that we must make an either/or choice between XX and YY.
XX and YY are not necessarily mutually-exclusive alternatives.
Adjusting XX and YY together might produce a better result.

6.A hasty generalization
We are informed that XXX, but we do not know whether all of ### prefer ###.
We can believe that XXX is indeed ###,but based on this slim information we can never evaluate the overall performance of YYY.

7.A fallacy of "after this ,therefore because of this"
The arguer unfairly assumes that XXX caused YYY, since many other reasons may explain that###.
Unless other possibilities have be considered and ruled out, the conclusion is unconvincing.

8.All things are equal.
The arguer commits a fallacy of "all things are equal".
The arguer assumes without justification that the background conditions have remained the same at different time and different places.


文章结构
In this argument, the arguer recommends that ####,to support this conclusion the arguer cites the result of a resent survey that ####,moreover the arguer points out that ####. As it stands ,the argument suffers from several critical flaws as follows.

First of all, the arguer commits a fallacy of ###.

In addition, the validity of the survey is open to doubt.#####

Finally, the argument is based on a gratuitous assumption that ####.

To sum up, the conclusion reached in the argument lacks credibility since the evidence cited in the analysis does not lend strong support to what the arguer claims. To make the argument more convincing, the arguer should provide more information concerning ####, to better evaluate the argument ,we need more concert evidence that ####, otherwise the argument is logically unacceptable.
