TPO20.1 正确率:11/14 ;错误题目:10, 13, 14
Paragraph 5: Two other developments presaged the end of the era of turnpikes and started a transportation revolution that resulted in increased regional specialization and the growth of a national market economy. First came the steamboat; although flatboats and keelboats continued to be important until the 1850’s steamboats eventually superseded all other craft in the carrying of passengers and freight. Steamboats were not only faster but also transported upriver freight for about one tenth of what it had previously cost on hand-propelled keelboats. Next came the Erie Canal, an enormous project in its day, spanning about 350 miles. After the canal went into operation, the cost per mile of transporting a ton of freight from Buffalo to New York City declined from nearly 20 cents to less than 1 cent. Eventually, the western states diverted much of their produce from the rivers to the Erie Canal, a shorter route to eastern markets.
10. The word "diverted" in the passage is closest in meaning to: 原选3,正选2 应该联系全句,将其产品转到Erie Canal。
O collected
O shifted
O transported
O sold
13. Look at the four squares [■] that indicate where the following sentence can be added to the passage.
In fact, goods could be shipped more cheaply across the much greater distance of the Atlantic Ocean than they could from western New York to coastal cities.
Where would the sentence best fit?

Transportation was becoming less of a problem for those who wished to move west and for those who had farm surpluses to send to market. ■Prior to 1815, western farmers who did not live on navigable waterways were connected to them only by dirt roads and mountain trails. ■Livestock could be driven across the mountains, but the cost of transporting bulky grains in this fashion was several times greater than their value in eastern markets. ■The first step toward an improvement of western transportation was the construction of turnpikes. ■These roads made possible a reduction in transportation costs and thus stimulated the commercialization of agriculture along their routes.
最后一句的road跟前面的turnpikes相连接,一个意思的顺承,当时若知道turnpikes的意思,或许就不会选第四个选项。插入句中的in fact有转折的意思,故放选项3后边合适。
14: 正确选项:1、3、5;我的选项:3、5、6
O The desire to improve their livelihood often inspired people to move west. 当时考虑这是一个小的方面,所谓的小观点不选,请同组同学们指正。
O Among the people who moved to the western United States were a number of artisans.
O The fertility of western farmland as well as favorable government policies supported agricultural gains.
O Steamboats were originally used to transport passengers rather than freight.
O Commercial farming in the West was greatly enhanced by improvements in land and water transportation.
O The transportation revolution resulted in regional economies that operated independently of a national market economy. 错误因为是全国性的市场。

Paragraph 1: The universal global warming at the end of the Ice Age had dramatic effects on temperate regions of Asia, Europe, and North America. Ice sheets retreated and sea levels rose. The climatic changes in southwestern Asia were more subtle, in that they involved shifts in mountain snow lines, rainfall patterns, and vegetation cover. However, these same cycles of change had momentous impacts on the sparse human populations of the region. At the end of the Ice Age, no more than a few thousand foragers lived along the eastern Mediterranean coast, in the Jordan and Euphrates valleys. Within 2,000 years, the human population of the region numbered in the tens of thousands, all as a result of village life and farming. Thanks to new environmental and archaeological discoveries, we now know something about this remarkable change in local life.
2. Major climatic changes occurred by the end of the Ice Age in all of the following geographic areas EXCEPT 原选1,正选2
O temperate regions of Asia
O southwestern Asia 属没看清原句…
O North America
O Europe
Paragraph 3: Thanks to extremely fine-grained excavation and extensive use of flotation methods (through which seeds are recovered from soil samples), we know a great deal about the foraging practices of the inhabitants of Abu Hureyra in Syria's Euphrates valley. Abu Hureyra was founded about 9500B.C, a small village settlement of cramped pit dwellings (houses dug partially in the soil) with reed roofs supported by wooden uprights. For the next 1,500 years, its inhabitants enjoyed a somewhat warmer and damper climate than today, living in a well-wooded steppe area where wild cereal grasses were abundant. They subsisted off spring migrations of Persian gazelles from the south. With such a favorable location, about 300 to 400 people lived in a sizable, permanent settlement. They were no longer a series of small bands but lived in a large community with more elaborate social organization, probably grouped into clans of people of common descent.
6. The word "cramped" in the passage is closest in meaning to 原选3,正选4
O primitive
O secure
O extended
O confined 我看括号里说房子的dug在地下呢,那不应该是extend到地下吗?求解
Paragraph 5: Five centuries later, about 7700B.C., a new village rose on the mound. At first the inhabitants still hunted gazelle intensively. Then, about 7000 B.C., within the space of a few generations, they switched abruptly to herding domesticated goats and sheep and to growing einkorn, pulses, and other cereal grasses. Abu Hureyra grew rapidly until it covered nearly 30 acres. It was a close-knit community of rectangular, one-story mud-brick houses, joined by narrow lanes and courtyards, finally abandoned about 5000 B.C.. Many complex factors led to the adoption of the new economies, not only at Abu Hureyra, but at many other locations such as 'Ain Ghazal, also in Syria, where goat toe bones showing the telltale marks of abrasion caused by foot tethering (binding) testify to early herding of domestic stock.
10. According to paragraph 5, after 7000 B.C. the settlement of Abu Hureyra differed from earlier settlements at that location in all of the following EXCEPT 原选1正选2
O the domestication of animals
O the intensive hunting of gazelle 不解,求解!
O the size of the settlement
O the design of the dwellings

Paragraph 1: When one considers the many ways by which organisms are completely destroyed after death, it is remarkable that fossils are as common as they are. Attack by scavengers and bacteria, chemical decay, and destruction by erosion and other geologic agencies make the odds against preservation very high. However, the chances of escaping complete destruction are vastly improved if the organism happens to have a mineralized skeleton and dies in a place where it can be quickly buried by sediment. Both of these conditions are often found on the ocean floors, where shelled invertebrates (organisms without spines) flourish and are covered by the continuous rain of sedimentary particles. Although most fossils are found in marine sedimentary rocks, they also are found in terrestrial deposits left by streams and lakes. On occasion, animals and plants have been preserved after becoming immersed in tar or quicksand, trapped in ice or lava flows, or engulfed by rapid falls of volcanic ash.
2. In paragraph 1, what is the author's purpose in providing examples of how organisms are destroyed? 原选2正选1
O To emphasize how surprising it is that so many fossils exist
O To introduce a new geologic theory of fossil preservation 没看完全段,选急了…
O To explain why the fossil record until now has remained incomplete
O To compare how fossils form on land and in water
Paragraph 2: The term "fossil" often implies petrifaction, literally a transformation into stone. After the death of an organism, the soft tissue is ordinarily consumed by scavengers and bacteria. The empty shell of a snail or clam may be left behind, and if it is sufficiently durable and resistant to dissolution, it may remain basically unchanged for a long period of time. Indeed, unaltered shells of marine invertebrates are known from deposits over 100 million years old. In many marine creatures, however, the skeleton is composed of a mineral variety of calcium carbonate called aragonite. Although aragonite has the same composition as the more familiar mineral known as calcite, it has a different crystal form, is relatively unstable, and in time changes to the more stable calcite.
5. Why does the author mention "aragonite" in the passage? 原选4 正选3
O To emphasize that some fossils remain unaltered for millions of years
O To contrast fossil formation in organisms with soft tissue and in organisms with hard shells
O To explain that some marine organisms must undergo chemical changes in order to fossilize
O To explain why fossil shells are more likely to survive than are fossil skeletons 含aragonite句子没有理解清楚,这是个问题啊,为啥老是出现这种理解不清的问题呢??
Paragraph 5: Another type of fossilization, known as carbonization, occurs when soft tissues are preserved as thin films of carbon. Leaves and tissue of soft-bodied organisms such as jellyfish or worms may accumulate, become buried and compressed, and lose their volatile constituents. The carbon often remains behind as a blackened silhouette.
9. Paragraph 5 suggests which of the following about the carbonization process? 原选3正选2
O It is completed soon after an organism dies.
O It does not occur in hard-shell organisms. 不理解为啥选2,我觉得3更佳啊,文中没有说不会发生在硬壳动物中,只是说软组织在被preserved as thin films of carbon时可发生carbonization
O It sometimes allows soft-tissued organisms to be preserved with all their parts.
O It is a more precise process of preservation than is replacement.
■Another type of fossilization, known as carbonization, occurs when soft tissues are preserved as thin films of carbon. ■Leaves and tissue of soft-bodied organisms such as jellyfish or worms may accumulate, become buried and compressed, and lose their volatile constituents. ■The carbon often remains behind as a blackened silhouette.■
13. Look at the four squares [■] that indicate where the following sentence can be added to the passage.
But the evidence of past organic life is not limited to petrifaction. 原选3,正选1;没有联系上下段落,当时做的时候也看了下上文,没发现petrifaction,故就以为木关系,就在段内插入。同组同学,你对了吗?咋做对的,当时咋想的?
Where would the sentence best fit?
