Works(Words) come to California when(of a) new weapon in a(the) war with household pe(s)ts. Two sites(scientists) working (for a firm in Anaheim,) of California have developed a method to eliminate insects without using dangerous chemical(s)---the new poison---hot air.
The basic idea is that insects can not adjust the temperature(s) much above normal. In laboratory experiment(s, cockroaches and termites) can(‘t) survive much (more) about a quarter of an hour at (125 degrees) Fahrenheit, or about 50 degrees centigrade.
The new method involves covering the(a) house with a huge tent and filling in with air and heat(ed) it around 50(65) degrees centigrade. Hot air is forced in with pans(fans) and the tent keeps the heat inside the house. Since xxx(termites) trying to escape by hide(hiding) in wooded beings(beams) the heat treatment must (be) continue(d) for (a) four(full) six hours. But when it’s all over, and the insects are dead, there are no toxic residues to endanger humans or pets, and no funny smile(s).
Scientists claim that there will be(is) no danger of fire either, since very few household materials will burn at 50(65) degrees centigrade. In fact, what(wood) is prepared for construction you still(use by) drying (it in ovens at) is 80 degrees centigrade which is substantially hotter than (the air used in) this procedure.

10月11日Listen to a talk given in a university class
In today’s class we’ll be examining some 19-century pattern books that were used for building houses. I think it’s fair to say that these pattern books were the most important influence on the design of north-America houses during the 19th century.
This (was) because most people who wanted to build a house couldn’t afford to hire an architect. Instead they bought a pattern book, picked out a plan and took it to the builder. The difference in cost was substantial. In 1870 for example, hiring an architect would(‘ve) accost about a hundred dollars. At the same time, a pattern book written by an architect cost only 5 dollars.
At that price, it’s easy to see why pattern books were so popular. Some are back in printed again today. And of course they cost a lot more than they did a hundred years ago. But they are invaluable resource for historians, and also for people who restore old houses. I have a modern reprint here that will(I’ll) be passing around the room at(in) a moment so that everyone could(can) have a look.

Listen to med-watch a radio program about medical news
Do you ever wonder why it is that most people are programmed to sleep at night instead of during the day? If there is something about the psych(cycle) of white(light) and dark that(‘s) telling us when to sleep? Then should the sleep psych(cycle) of a blind person be different? As it turns out, many blind people, people with no visual perception of light at all, do have the same sleep psych(cycle) of the(as) sighted people.
So now you are wondering how can this happen. The answer is hormones, one hormone in particular, it’s called melatonin. Inside of(In sighted) people, the level of melatonin goes up at night or when it’s dark, or goes down in the day or when it’s light. It’s believed that it’s the presence of this hormone in the blood that gives us the urge to sleep. If (an) increase the(in) melatonin level program(s) sighted people to sleep at night., then what about blind people?
A researcher named Doctor Charles Czeisler tells us about an interesting experiment. He tried shining a bright light into the eyes of some blind people. When he did this, he noticed that the level of the melatonin in the blood of these subjects went down, just as it would do for sighted people. Somehow the eyes of these subjects even though they were damaged and had no visual perception of light, could tell their brain when there was more or less light. Now this doesn’t work for all blind people. In fact, most of Czeisler’s subjects had no hormonal over response to light at all. Further research may be able to explain the sensibility to light in terms of the type of blindness of the subject.

Listen to part of a lecture given in a marine biology class
To us, the environment of which fish dwell often seems cold and dark and mysterious. But there are advantages to live(living) in water, and they’ve played an important role of making fish what they are. One is that water isn’t subject to sudden temperature changes. Therefore it makes an excellent habitat for a cold-blooded animal. Another advantage is the water’s ability to easily support body weight. Probab plasent(Protoplasm) has (approximately) the same density as water. So a fish in water is almost weightless. This “weightless” in term(turn) means two things. One, a fish can get long with a light weight and simple bone structure. And two, limitations to a fish’s size are practically removed.
Yet, there is one basic difficulty to live in water---the fact that is incompressible. For a fish to move through water, it must actually shove (it) aside. Most can do this by wiggling back and forth in snakelike motion. The fish pushes water aside by the forward motion of its head, and with the curves of its body and its flexible tail. Next, the water flows back along the fish’s noing insides(narrowing sides), closing to(in at) the tail, and helping the fish propel itself forward.
The fact that the water is im(com)pressible has literally shaped the development of fish. A flat and angular shape can be moved through water only with difficulty. And for this reason, fish have a basic shape that is beautifully adapted to deal with this particularity(peculiarity).

Good afternoon. I’m here today to talk to you about a career with our airline. We are especially interested in recruiting people to fulfill (openings for) flight attendants.
First of all, to work as a flight attendant with us, you must be expected(accepted) into our training program. And with so many people applying it’s not easy to be selected. From a(the) thousand(s) of applications that we received annually, we chose fewer than a thousand people for training. So we require experience serving the public. And it also helps if you have (earned) some college credits.
Also not everybody who gets accepted into the training program makes it through.
The course needs six days a week for five weeks. The training includes extensive classroom working (in) such subjects as Thursday(first aid) and passenger psychology as well as practical training in (flight procedures) passengers and meal service. A lot of our graduates saved of(say that) our flight attendants developed the skill(s) of nurse, a headwaiter and a public relation(s) executive.
But as a flight attendant myself, I can see that all of the hard work is worth it, of course I get to travel throughout the country and the airline pays all of my expenses when(while) I’m away from base station. And what I like best of all is that I(‘ve) made friends with people from all over the country.

Last time, we talked about Anne Bradstreet (and) a(the) role of the women in the purity(Puritan) colonies. Today, I want to talk about some other women who’ve contributed to American history---some famous and some not so famous. The first woman I’d like to talk about is Molly Pitcher. Those of you who are familiar with the name may know her as a hero of the American Revolution. But in fact, there never was a woman named Molly Pitcher. Her real name was actually Mary Ludwig Hays. She got the nickname Molly Pitcher for her excellent(acts of) bravery during the Revolutionary War.
As the story goes when Mary’s or Molly’s husband John Hays enlisted in the artillery, Mary followed like many other wives did. She had dealed(helped out) doing washing and cooking for the soldiers. She was known to be a pretty unusual woman, she smoke the(a) pipe and shoot(chewed) tobacco.
Anyway, in the summer of 1778 at the battle of Monmouth it was a blistering hot day---maybe over 100 degrees---and 50 soldiers died of thirst during the battle. Molly wasn’t content to stay back at the camp. Instead, she ran through gunshots and can(n)on fire carrying water in pitchers from a small stream onto(out to) the thirsty American soldiers. The relieve(relief) the(that) chief broad(she brought) with the(her) pitchers of water gave her the legendary nickname Molly Pitcher. The story also says she continued to load and fire his husband’s cannon after he was woulded. They say that she is so well liked by the other soldiers that they called her Surgy Molly. In fact legend has it that George Washington himself gave her the special military title.

I’d like to begin by thanking Dr. Kane for inviting me to be here today. Although I’m not a geologist, I have been collecting minerals for years. My collection is really diverse, because I(‘ve) travelled all over the world to find them. Today, I(‘ve) brought a few specimens for you to see. After I discuss each one, I’ll pass around so that you can look at it more closely.
As you know, those bars(feldspars) are the most abundant minerals, and are derided(divided) into a number of types. These first samples are osclathes(orthoclases). Notice that they are wearing(vary in) color from white to pink to red. This glassy one is found in a volcanic rock. In fact, I found it in New Mexico on a collecting trip.
This next sample that I’ll pass around is a microcline mineral, also called amazonstone. You can identify it by its bright green color. It’s often used in jewelry and really is quite attractive.
These final samples are all playgeoclisefells bars(plagioclase feldspars). Many playgeoclises(plagioclases) are very rare. So I’m particularly proud of the variety in my collection.
I’ve also brought a few slides of some larger mineral samples. And if you(‘ll) turn up(out) the lights now, I’d like to show them to you.

Listen to part of a lecture in a zoology class
Before I tell you about the interesting discovery related to Tyrannosaurus rex, I need to review something we studied last semester---the difference between what are commonly called “cold blooded” and “warm blooded” animals. In warm blooded animals, birds and mammals for example, the body temperature normally stays with a narrow range, no matter what the outside temperature is. As a result, a warm blooded animal is usually active at(in) both cold and hot weather, because its body temperature can adjust to the temperature of the(its) environment.
On the other hand, cold blooded animals, such as most reptiles and fliands(amphibians) and insects, are not able to create enough heat internally to raise their temperature above the temperature of the environment. So, for example, the temperature of a cold blooded animal falls when the environment is cool.
I hope this distinction is clear. Now, moving on to Tyrannosaurus rex. You may know that dinosaurs being reptiles are generally believed to have been cold blooded. Well, a recent research study found that the chemical composition of the bones of Tyrannosaurus rex was consistent with the bones of an animal that has a very narrow range of internal temperature, indicating that it was probably warm blooded.

This room is devoted to electric fish. The eel in the tank behind me can produce a strong stroke(jolt) of electricity to stunt its prey. But most of the fish in here produce only weak electrical impulses that are useful for navigating, locating food and even for communicating.
The knife fish is a good example. This fish navigates using tiny receptors in the skin that are sensitive to electrical impulses. The knife fish produces an electrical signal and the receptors in the(its) skin let it know when the signal is distorted by a tree rood(root) or some other optical(obstacle) so it can go around it.
Fish also use the ability to produce undetected(and detect) electrical signal impulses to communicate. They can tell each other what species they belong to, how big they are, and whether they are male or female. We have a tank here that’s especially equipped to covert the inaudible signals that(the) fish produce into sounds you can hear when you put on (these) headphones. I urge you all to listen in when I’ve(I’m) done speaking.
Now have a look at the electric raze(rays). Raze(Rays) are especially interesting to medical researchers because of the organs they use to produce electricity. These organs can contain a chemical that carries signals from one nerve and into(ending to) the next, not only in raze(rays) but also in people. By studying these organs, scientists hope to learn more about diseases that interrupt the transmission in impulses from one nerve to another.

You might think that most of the patients at sleep clinics are being treated for sleeplessness, commonly referred to as insomnia. But that is not the case. The majority of sleep clinic patients suffer from disorders of excessive sleep, or hypersomnia. Well(While) most insomnia(cs) and ex-patients are(somehow) managed to drug(drag) themselves through the day and functional (at acceptable) although (not) optimal levels. This is not so for people who suffer from hypersomnia.
They are incapacitated by xxx(irresistible) urges to sleep during the day, often in inappropriate situations, at business meetings, in super-markets, or (at) parties. Even (more) dangerous, is there(their) failure to remain awake when driving or operating machinery. Falling asleep in such situations could obviously be life threatening.
Many hypersomnias suffer from narcolepsy, for which the primary (symptom) is excessive day-time sleepiness. Do(Though) not apparent in the childhood, the symptom most often appears for the first time during the teen years, and continued throughout the(a) person’s life. The sleep attack(s) may occur as many as fifteen to twenty times during the course of the day and last for periods from fifteen minutes up to two hours.
What can be done to help those suffering from narcolepsy? There are certain drugs that can help and specialists suggest volunteering(voluntary) napping to decrease the frequency of such sleep attacks.

Listen to a talk in a geology class
Now, you’ve been reading articles about the tremendous damage down(done) to life and property by earthquakes. That’s why seismologists have been working so hard to develop methods of earthquake prediction. We can now predict earthquakes fairly well, but the predictions only locate potential areas of danger. They won’t(don’t) predict the specific time and location has which the(an) earthquake is likely to occur. Today I want to introduce to you three prediction models that have been developed.
The first prediction model looks along earthquake faults, those cracks on(in) the Earth(‘s) crost(crust), the fine of the(to find what are known as) seismic gaps. Seismic gaps, so(are) places were(where the fault has) the show(n) little or no seismic activity for a long time. This theory postulates that such places are due for a major shock.
The second model relies on phenomena, like ground tube(tilt). Using long cenlengical(cylindrical) tube(s) containing water, observers noted that ground tube(tilt) tend(ed) to occur before major earthquakes. This let(led) them to correctly predict the big Hi Chung quake of 1975---the first successful earthquake prediction scientists have ever make. A million people were evacuated from that (Chinese) city before the earthquake struck. Unfortunately this method hasn’t work(ed) consistently. So we can’t say it’s been perfected.
The third model is based on the theory that major earthquakes closely followed with (a) series of minor ones. Starting with the measurements and timing of the smaller quakes, a complex formulate calculate(s) the time(s) of increase probability of a much larger quake. Right now this method like the first method can not predict specific time(s) and places. But that may change as it is further developed.
For the moment, none of these models can predict with reasonable levels of confidence.

Listen to part of a lecture in a literature class
Yesterday we talked the anecdote. Today, we are going to move on to one of the most popular literary forms in western literature, the short story.
The short story is a piece of prose fiction, usually under 10 thousand words. Although it’s similar to the anecdote, it’s really a separate literary form. You remember that the anecdote’s sole purpose is to entertain, and (that) it does this by relating a curious and(or) interesting advent(event). Well, there are also advents(events) in short stories. But the short story uses the advent(event) and(as) something of(a) character re-ask(reacts) to --- the readers’ interest is captured by the effect of(that) this advent(event) has on the character’s (in) the story. We’d(We’re) even like(ly) to reread a short story to better understand the character who is being portrayed and why is (a) certain advent(event) lead(led) to a certain response action.
A short story though is not just a short novel. A novel is narrative --- it tells the details(detailed) story that usually takes place over a long period of time. But(A) short story is less comprehensive than a novel, and the focus is on a character’s mental reaction to (an) experience --- this reaction is the heart of the short story.
Now I want you to think back to the short story you read for homework and I will give you a list of questions to think about.

Listen to part of a talk in an oceanography class
One of these the(reason) oceanographer analyzed the segments(sediment) of(on) the ocean floor It’s(is) to see how long-term(s) changes in earth’s temperature, have a sec of a(affected the) depth of the ocean. By analyzing the remains of sea animals in old layers of ocean segment(sediment), oceanographers can determine the depth of the ocean in the past. They(‘ve) analyze(d) hundreds of such layers, including some from the coldest period(s) of earth’s history---the ice ages. What they(‘ve) found is that during the ice ages, the amount of water in the ocean(s) stayed crest(decreasd). Water level(s) in the ocean dropped by about four hundred feet. Water from the ocean evaporated and became frozen in continental glaciers, so it didn’t drain back into the ocean. When temperatures eventually rose again, the glaciers mounted(melted) and oceans returned to their former depth(s). Analyst(Analysis) of sedimentary data indicates that period(s) of glacial freezing and melting, occurred in regular circles of 20 thousand, 40 thousand and 100 thousand years.
Oceanographers are interested in the history of seawater levels, because they helped(hope) to use this historical data, in order to predict the possible effect that global warming could have on seawater levels. If industrial pollutions(pollutants) are capable of heating global temperatures to the point that glaciers begin to melt, it is urgent for us to know precisely how high sea levels will rise as a result.
