Oxygen and nitrogen can be made from other materials, but they are usually obtained from the air because air is so plentiful. Some of the other gases, such as argon, can only be obtained from the air. There is so little carbon dioxide in the air that it is better to obtain it in other ways. The problem, of course, is to find q quick and useful way of separating the gases in the air. Let us read how this is done.We remember how air can be made into a liquid. If the liquid is warmed again, It "boils" and turns back into a gas. Now oxygen does not boil away from liquid air so easily as nitrogen. By careful arrangement of the boiling, it is possible to make the nitrogen turn back into a gas and leave the liquid oxygen behind. The oxygen can be turned into a gas later. In This way the oxygen and nitrogen are separated. The other gases, such as argon, can also be obtained separately by very careful arrangement of the boiling.Questions.Why people usually obtain oxygen and nitrogen from the air?What happens if the liquid is warmed again? Does nitrogen boil easily than oxygen does? Can the nitrogen turn back into a gas?How are oxygen and nitrogen separated? Passage 1l)Because air is plentiful.2)It boils and turns hack into a gas.3)Yes, it does.4) Yes, it can.5)Make the nitrogen turn back into a gas and leave the liquid oxygen behind.Passage 2Scientists call the process of water spreading over a surface wetting.But water doesn't always do a good job of wetting a surface. You've probably noticed this when looking at the surface of a waxed car after a rain. The water sits on the car in tiny beads. That's because the water molecules are strongly attracted to one another. They tend to bunch together which makes them form beads. However, chemicals called surfactants can weaken the attraction of water molecules for one another. (They weaken the surface tension.)So surfactants are put in detergents to allow the water to spread out on a surface. (Lowering surface tension also causes detergents to form suds. But suds aren't a necessary part of the cleaning process. )A detergent molecule has two ends. One end is hydrophilic ("water loving"). That is, it is attracted to water. The other end is hydrophobic. That is, it is repulsed by water, However, this hydrophobic end of a detergent molecule is attracted to substances such as fats. The re suit? With the help of some mechanical action, like scrubbing or tumbling, the hydrophobic end of the detergent molecule drags the fat off the surface to he cleaned while the hydrophilic end pulls the fat into the water. So when the water heads for the drain, down goes the fat with a nice sounding gurgle, leaving a clean dish or even a clean sea bird behind.Questions:How many ends does a detergent molecule have?What happens on a waxed car after a rain? What function do surfactants have?Which end of the detergent molecule pulls the fat into the water?What does the word "hydrophilic" mean? Passage 2A detergent molecule has two ends.The water sits on the car in tiny heads.It can allow the water to spread out on a surface.The hydrophilic end pulls the fat into the water.Hydrophilic is one end of a detergent molecule which is attracted to water.Passage 3Since no one knows what scientific discoveries will be made between now and the year A.D. 2000, each of us can make his own predictions.With the scientific information that we have available now, let’s make and estimate of progress in air travel. It is likely that within 50 years we shall travel through the air at a speed of 10,000 miles per hour. Too fast? Not at all. Jet-propelled planes can now travel at least 1,000 miles an hour, and jet planes will be outmoded shortly by guided missiles. The X—15 rocket's speed in 1561 was 3,690 miles per hour, and scientists are hoping to double and even triple this speed. They will accomplish this speed--up, because there is no apparent scientific obstacle to prevent it.Some day. certain aerodynamic problems will be overcome and missiles will he enlarged to carry at least 25 passengers. When scientists have solved all the problems of constructing and increasing the speed of apparatus--carrying missiles. their skill will lead them to the next step-missiles for interplanetary flight. This prediction is a scientific possibility in the near future.Questions :l) How fast do jet--propelled planes travel now?2)Is it possible for a missile to carry 24 passengers some day?3) In what conditions will scientists invent missiles for interplanetary flight?4)Is there any apparent scientific obstacle for the X--15 rocket’s speed to become 7,380 miles per hour?5)Is it likely that we will travel through the air at a speed of 10,000 miles per hour in 2060?Passage 3l)It can now travel at least 1,000 miles per hour.2) Yes, it is.3)When scientists have solved the problems of constructing and increasing the speed of apparatus-carrying missiles.4)No, there isn't.5) Yes, it is.Passage 4If you live in a large city, you are quite familiar with some of the problems of noise, but because of some of its harmful effects, you may not be aware of its influence on human behavior. In recent years there has been a great deal of interest in the effects of noise on human behavior, and concepts such as "noise pollution" have arisen.Exposure to loud noises can definitely produce a partial or complete loss of hearing depending on the intensity, duration, and frequency composition of the noses. Many jobs present noise hazards, such as working in factories and around jet aircraft, driving farm tractors, and working(or sitting)in music halls where rock bands are playing. In general, continuous exposure to sounds of over 80 decibels can be considered dangerous. If exposure is for a sufficient period of time, it may produce significant hearing loss.Noise can have unexpected harmful effects on performance of certain kinds of tasks, for instance, if one is performing a watch keeping task that requires vigilance, in which he is responsible for detecting weak signals of some kind.Communication with other people is unfavorably affected by noise. If you have ridden in the area of a jet transport, you adjusted the loudness of your speed to compensate for the effect. The problem is noise.Questions:What is the purpose of the passage?What jobs can bring noise problems?Why is it difficult to carry on a conversation in the rear of a jet transport at first?Where are there generally more problems of noise?What is noise pollution?Passage 4The purpose of the passage is to define the effects of noise on human behavior.Jobs such as working in factories and around jet aircraft, driving farm tractors, and working(or sitting)in music halls where rock bands are playing can bring noise problems.Because it is very noisy there.There are generally more problems of noise in large cities.Noise pollution is the harmful influence of noise on human behavior.Passage 5Most teachers agree that the best way to learn a language is to immerse yourself in the environment and culture of that language.One way to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.The satellite was directed into an area known as Manhattan. Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to the feasibility of a manned flying saucer landing on Earth. A press conference washeld at the Venus Institute of Technology."We have come to the conclusion, based on last week's satellite landing', Prof.Zog said," that there is no life on Earth. ""How do you know this?" The science reporter of the Venus Evening Star asked."For one thing, Earth’s surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide andother deadly gases and nobody could possibly breathe this air and survive. ""What does this mean as far as our flying saucer program is concerned?""We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned. ""Are there any other hazards that you discovered in your studies?""Take a look at this photo. You see this dark black cloud hovering over the surface of Earth? We call this the Consolidated Edison Bell We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there. "'Over here you will notice what seems to be a river, but the satellite findings indicate it is polluted and the water is unfit to drink, This means we shall have to carry our own water, which will add even greater weight to the saucer. ""Sir ,what are all those tiny black spots on the photographs?""We are not certain. They seem to be metal particles that move along certain paths. They emit gases, make noise and keep crashing into each other. There are so many of these paths and so many metal particles that it is impossible to land a flying saucer without its being smashed by one. "“What are those stalagmite projections sticking up?""They are some type of granite formations that give off light at night. Prof. Glom has named them skyscrapers since they seem to be scraping the skies. ""If all you say is true, won't this set back the flying saucer program several years?""Yes, but we shall proceed as soon as the Grubstart gives us the added funds. "‘Prof.Zog, why are we spending billions and billions of zilches to land a {lying saucer on Earth when there is no life there?""Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere.Qutestions:1)What caused the excitement on the planet Venus?2)What led the Venusian scientists to believe that there is no life on Earth?3)What, according to Prof.Zog, will add weight to the saucer?4)Why does Prof. Zog think it impossible to land a flying saucer on Earth without its being smashed?5)What do the "tiny black spots"refer to, in fact?6)The tone of the essay is .7)The purpose of the author in writing this book is .8)What does the "dark cloud”on the photograph allude to(暗指)?Passage 91)For the first time Venusian scientists managed to land a atellite on the planet Earthand it has been sending hack signals as well as photographs ever since.For one thing, Earth's surface in the area of Manhattan is composed of solid concrete and nothing can grow there.

Passage 8I would like to propose that for sixty to ninety minutes each evening, right after the early evening news, all television broadcastingin the United States be prohibited by law.Let us take a serious, reasonable look at what the results might be if such a proposal were accepted. Families might use the time for a real family hour. Without the distraction of TV, they might sit around together after dinner and actually talk to one another. It is well knownthat many of our problems--everything, in fact, from the generation gap to the high divorce rateto some forms of mental illness are caused at least in part by failure to communicate. We donot tell each other what is disturbing us. The result is emotional difficulty of one kind or another. By using the quiet family hour to discuss our problems, we might get to know each other better, and to like each other better.On evenings when such talk is unnecessary, families could rediscover more active pastimes. Freed from TV, forced to find their own activities, they might take a ride together to wach the sunset. Or they might take a walk together(remember feet?)and see the neighborhood with fresh, new eyes.With free time and no TV, children and adults might rediscover reading. There is more entertainment in a good book than in a month of typical TV programming. Educators report thatthe generation growing up with television can barely write and English sentence, even at the college level. Writing is often learned from reading. A more literate new generation could bea product of the quiet hour.A different form of reading might also he done, as it was in the past: reading aloud. Few pastimes bring a family closer together than gathering around and listening to mother or father read a good story. The quiet hour could become the story hour. When the quiet hour ends,the TV networks might even be forced to come up with better shows in order to get us hack fromour newly discovered activities.At first glance, the idea of an hour without TV seems radical. What will parents do with out the electronic baby-sitter? How will we spend the time? But it is not radical at all. Ithas been only twenty-five years since television came to control American free time. Those of usthirty--five and older can remember childhoods without television, spent partly with radio- which at least involved the listener’s imagination--but also with reading, learning, talking, playing games, inventing new activities. It wasn't that difficult. Honest. The truth is we had a ball,Questions:What is the writer’s proposal?In part at least, what caused the generation gap, high rate divorce rate and some forms of mental illness problems?According to the author, what could help to turn out a more literate new generation?What effect might the idea of an hour without TV have on the TV networks?What is the main idea of this passage? Passage 81)The proposal is that for sixty to ninety minutes each evening, right after the early evening news, all television broadcasting in the United States he prohibited by law.2)They are caused in part at least by our failure to communicate.3)Turning off TV for an hour every evening.4)They might even be forced to come up with better shows.5) We should show no television programs for about one hour every evening.passage 9There was great excitement on the planet of Venus this week, for the first time Venusian scientists managed Presently there came behind us the sound of a heavy tread, and before you could say "Jack Robinson", a policeman was standing in front of me, his notebook open, and a determined look on his face."Excuse me, sir. "he said, "you have a remarkable voice, if l may say so, Who taught you singing? I'd very much like to find someone who can give my daughter singing lessons. Would you be kind enough to tell me your name and address? Then my wife or l would drop you a line and we could discuss the matter. "Questions:1)When did "the writer and his friend walk home one evening?2)Where had they been?3)Why did his friend ask him to be quiet?4)What did they hear soon?5)Why did the policeman want to know his name and address?Passage 61)Long after most people had gone to bed./Late one evening.2)They had been to a musical.3)Because his friend thought that he would give everybody a fright and wake people up for miles around. Besides, they would think them drunkards.4)The sound of a heavy tread.5)He wanted to ask him to give his daughter singing lessons.Passage 7One evening last week, my wife and I were sitting quietly at home. She was watching TV while 1 was reading a hook. Suddenly we heard a loud band. f supposed that the old lady in the flat above ours was moving the furniture about. My wife was afraid that the noise would make the baby. She turned down the television and a moment later we heard someone calling for help.I ran upstairs. The old lady's door was shut, but I could see smoke coming through the letterbox and under the door, and could smell something burning. "the flat is on fire, "I shouted down to my wife," ring the fire brigade. "I hanged on the door, but the old lady tooka long time to answer. I was turning over in my mind the idea of breaking the door down when she finally appeared."I was having a bath," she said, "when the water heater in the kitchen blew up. ""Why didn't you open the door?' I asked her. "1 was getting dressed when you knoeked, "she said, looking embarrassed.I took her downstairs to our flat. Then I ran back, went inside the old lady’s flat and turned the gas off to prevent another explosion. Smoke was pouring out of the kitchen and the heater was in flames. Just then I heard a ~ire engine arriving outside and the heavy footsteps of the firemen on the stairs. 1 looked round and noticed two of them standing in the doorway.“It’s in here.” I said."You turned up promptly, I must say. "When I got back to our flat, my wife was making the old lady a cup of tea. Soon afterwards, the fire chief came in to ask some questions. It turned out that the fire was not very serious and the firemen were already putting it out when they left, my wife went up with the old lady to help her clear up the mess.When she returned, my wife remarkedz "it's all right now. Nothing was damaged except the heater. But wasn't it lucky that Baby slept through all that noise?"She took the teacups into the kitchen and I heard her scream and the cups crash to the floor. When I got there, water was dripping slowly from the ceiling and forming a pool on the floor. The baby woke up at last and started to cry. Questions1)Why did the author know the flat was on fire?2)Why didn't the old lady open the door?3)What was the lady doing when the water heater in the kitchen exploded?4)Why did his wife go upstairs with the old lady when the firemen left?5)Why did his wife scream?Passage 7He saw smoke coming through the to do is to live with your teacher during your course. The obvious advantage of homestay is that, through the course, you only speak English and you do not meet other students who speak your native language. Also, total immersion in an English- speaking environment helps you avoid picking up common mistakes and 'had' language habits from fellow learners.For most students, however,it is the tailor--made teaching that homestay provides which makes them decide to choose these courses. "People like homestay because it allows them to concentrate on their own weakness. If you have a pronunciation problem, for example, youdon't want to sit in a class with 20 other students discussing how to pronounce a particular word. "At a more personal level, living with the teachers and their families can help you learn about British life and culture.To make sure the environment is right for the individual, it is very important that each student be matched with the right host family. This is the job of homestay organizations, which act as intermediaries between teachers and students through interviews and surveys.The disadvantage to homestay is, obviously, the cost. A two--week course, including full board and 15 hours of classes per week, will cost about $1000. And prices are higher when English for Special Purposes is needed. This means that homestay programs are generally more popular with older students, particularly professionals. The average age is between 17 and 35, and most organizations specially make mature students the targets.At present, homestay programs do not come under any quality guarantee schemes. The British Council and other inspection groups expect that, by the end of 1995, homestay programs will have their own quality scheme. But, as yet, no methods of monitoring and inspection have been agreed upon. This is likely to be a major logistical problem as many operators have hundreds of teachers running course all over the country.

We had been to a musical, and were talking about the people we had seen and heard in it."That show made him a star overnight,' said my friend about one of them. "He was completely unknown before. And now thousands of teenagers send him chocolates and love letters by every post. ""I thought him quite good,' I said, "but not worth thousands of love letters daily. As a matter of fact, one of his songs gave me a pain. ""What was that? "my friend asked. "Sing it to me. "I burst into a parody of the song."Be quiet, for heaven's sake. "My friend had given me an astonished look. "You'll give everybody a fright and wake people up for miles around. Besides, they'll think you a drunkard, and me too, probably. And then we'll have a policeman after us. ""Never mind," I sold, intoxicated more with the sound of my own voice than with the few drinks we had. "I don't care. What does it matter?" And I went on singing him the latest tunes at the top of my voice.breathe this air and survive.They will have to take oxygen and water with them.Because there are so many paths and so many metal particles.Vehicles.Humorous and satirical.The author wishes to call our attention to the fact that modern man has polluted his environment to such an extent that he might destroy himself if he went on like this.The polluted air hovering over the surface of Earth.Passage 10What is intelligence, anyway? When I was in the army I received a kind of aptitude test that all soldiers took and, against a normal of 100, scored 160. No one at the base had ever seen a figure like that and for two hours they made a big fuss over me. (It didn't mean anything, the next day I was still a buck private with KP as my highest duty)All my life I've been registering scores like that, so that 1 have the complacent feeling that I'm highly intelligent, and I expect other people to think so, too. Actually, though, don't such scores simply mean that I am very good at answering the type of academic questions that are considered worthy of answers by the people who make up the intelligence tests—people with intellectual bents similar to mine?For instance, I had an auto--repair man once, who, on these intelligence tests, could not possibly have scored more than 80,by my estimate.I always took it for granted that I was far intelligent than he was. Yet, when anything went wrong with my car 1 hastened to him withit, watched him anxiously as he explored its vitals, and listened to his pronouncements as though they were divine oracles--and he always fixed my ear.Well then, suppose my auto--repair man devised questions for an intelligence test, or suppose a carpenter did, or a farmer, or, indeed, almost anyone but an academician, By everyone of those tests, I' d prove myself a moron. And I'。
