Because we can feel that things are heavy, we think of weight as being a fixed quality in

an object, but it is not really fixed at all. If you could take a one pound packet of butter 4,000 miles out from the earth, it would weigh only a quarter of a pound.

Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space？ The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center (in other words the radius[半径] of the earth is 4,000 miles). When we took the butter 4,000 miles out, it was 8,000 miles from the center, which is twice the distance.

If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (成三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four ) and so on.

The best title for this passage is______.

A．The Earth Weight

B．Weight in Space

C．Changing Weight on the Earth

D．Weight on and off the Earth

（英语类学生必做）

Sleep is important to us because it helps restore organs and tissues in our body. But how much sleep do we actually need？

For most of us, eight hours seems to be about the right amount. Yet we know that there are many people who get 【61】 perfectly with less sleep, and some who may need 【62】 A great deal depends on the 【63】 we live. But a good general rule 【64】 is to sleep as long as we have to in order to feel happy and be able to work 【65】 our best when we awaken.

There are actually different 【66】 of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest it gets in a 【67】 sleep, 【68】 after eight hours of a shallow sleep we may still feel tired. But a short, deep sleep can be very 【69】 Alexander—the Great Emperor was able to get a deep sleep 【70】 he needed it. Once, during the night before an important battle, he remained 【71】 longer than anyone else. 【72】 he wrapped himself in a cloak and 【73】 down on the earth. He slept so 【74】 that his generals had to wake him three times for him to give the 【75】 to attack!

Normally when we go to sleep, our " sleep center" blocks off nerves so that 【76】 our brain and body go to sleep. 【77】 prevents us from wanting to do anything, and the other 【78】 our internal organs and limbs go to sleep. 【79】 sometimes only one goes to sleep and the other does not. A very tired soldier can sometimes 【80】 asleep (brain sleep) and keep on marching, because his body is not asleep.

When we talk about intelligence we do not mean the ability to get good scores on certain

kinds of tests or even the ability to do well in school. By intelligence we mean a way of living and behaving,especially in a new situation. If we want to test intelligence,we need to find out how a person acts instead of how much he knows to do.For example,when in a new situation,an intelligent person thinks about the situation,not about himself or what might happen to him. He tries to find out all he can do,and then he acts immediately and tries to do something about it. He probably isn’t sure how it all works out,but at least he tries. And if he cannot make things work out right,he doesn’t feel ashamed that he failed,he just tries to learn from his mistakes. An intelligent person,even if he is very young,has a special outlook in life,a special feeling about life,and a special way of how he fits into it.If you look at children,you’ll see a great difference between what we call "bright" children and "not bright" children. They are actually two different kinds of people,not just the same kind with different amounts of intelligence. For example,the bright child really wants to find out about life—he tries to get in touch with everything around him. But the unintelligent child keeps more to himself and his own dream world; he seems to have a wall between him and life in general.

1.According to this passage,intelligence is the ability to （）.

A、work by oneself do well in any

B、situation

C、know what is right and wrong

D、adapt oneself to a new situation

2.Why does an unintelligent child seem to have a wall between him and life in general？（）

A、Because he can hardly see the outside world.

B、Because life is far away from him.

C、Because he knows nothing about life in general.

D、Because he has little interest in things around himself.

3.In a new situation,an intelligent person （）.

A、knows more about what might happen to him

B、is well-prepared for his action

C、pays greater attention to the situation

D、completely ignores himself

4.If an intelligent person failed,he would （）.

A、feel ashamed about the failure

B、learn from his experiences

C、find out what he can’t do

D、make sure what’s wrong with his outlook in life

5.An intelligent child （）.

A、learns more about himself

B、shows interest in things around him

C、studies everything that may be interesting

D、looks down upon unintelligent children

Colors are sometimes called hot，cold，or neutral(中性). Red and yellow are said to be hot

colors because they make a room feel warmer and the walls nearer to us than they really are. We say that blue and green are cold because they give us the opposite feeling. A neutral color is one that does not seem to affect our feelings. Brown and grey are both neutral，and they may also be mixed with hot or cold colors to reduce their effect on our feelings.

We can begin to see the importance of color selection. Although red might be perfect for a restaurant，it would be wrong for an art exhibition room，where we want to look at the paintings，not at the walls behind. Because of its effect on size，white could be used to make a small room seem larger，or dark blue to make a large one seem smaller.

Another way that we sometimes speak of colors is to say that they are loud or quiet. Again we are talking about the feeling that colors give us. We use sound to express how much colors catch our attention.

16. If a man wants to make a room warmer，which color will he choose for the walls？

A. Green.

B. Yellow.

C. Black.

D. Brown

17. Which color can be used with blue to reduce its effect on our feelings？

A. Yellow

B. Red

C. Grey.

D. Green.

18. According to the second paragraph，red is most suitable for _____________.

A. restaurants

B. paintings

C. an exhibition room

D. the walls in a

living room

19. People would paint a small room into white because ____________.

A. white makes a room brighter

B. white makes a room prettier

C. a room seems larger in white

D. a room seems smaller it white

20. “Loud” and “quiet” colors give people ____________.

A. the cooler feelings

B. the opposite feelings

C. the warmer feelings

D. the similar feelings

第4题

For years people have been saying that the railways are dead. We all keep hearing that

trains are slow, that they lose money, that they’re dying. But this is far from the true. In these days of expensive oil, the railways have become highly competitive with motorcars and planes. If you want to carry people or goods from place to place, they’re cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. What is more, a railway takes you from the heart of a city center. It doesn’t hold you up as a car does, in endless traffic jams. And a single train can carry goods which no plane or motorcar could ever do.

Far from being dead, the railways are very much alive. Modern railway lines give you a smooth, untroubled journey. Where else can you eat well, sleep in comfort, feel safe and enjoy the scene while you are traveling at speed at the same time？ And we are only at the beginning. For we have just entered the age of super-fast trains, trains traveling at 150 miles an hour and more. Soon we will be wondering why we spent so much on motorways we can’t use because we have not enough money to buy the oil and planes we can’t fly in for the same reason.

1. Some people think the railways are dead for many reasons EXCEPT that ____.

A. planes and motorcars have taken the place of trains

B. oil is expensive today

C. trains are slow

D. railways lose money

2. The writers idea seems to be that ______.

A. we can do without railways

B. trains have much in common with motorcars and planes

C. motorcars and planes are not as good as trains

D. trains are as good as motorcars and planes

3. According to the writer, which of the following is NOT the advantage of railways？

A. It is cheaper to travel by train than by plane.

B. Super-fast trains travel even faster than planes.

C. The railway station is usually at the center of a city.

D. A train carries more goods than a motorcar or plane does.

4. The writer thinks that the railways, far from being dead, are very much alive because ___________.

A. we can have a smooth and untroubled journey

B. we’ll not have enough money to fly everywhere

C. we can now travel in super-fast trains

D. all of the above

5. The best title for this passage may be ________.

A. The Best Choice: Train, Motorcar or Plane

B. The Dying Railways

C. Super-fast Trains in the Future

D. Not the End, But the Beginning

Culture shock is an occupational disease （职业病) for people who have been suddenly transp

Culture shock is an occupational disease (职业病) for people who have been suddenly transplanted abroad.

Culture shock is caused by the anxiety that results from losing all familiar signs and symbols of social intercourse. Those signs are as following: How to shake hands and what to say when meeting people, when and how to give tips, how to make purchases, when to accept and refuse invitations, when to take statements seriously and when not. These signs, which may be words, gestures, facial expressions, or customs, are acquired by all of us in the course of growing up and as much a part of our culture as the language we speak or the beliefs we accept. All of us depend on hundreds of these signs for the peace of our mind and day-to-day efficiency, but we do not carry most at the level of conscious awareness.

Now when an individual enters a strange culture, all or most of these familiar signs are removed. No matter how broadminded or full of good will you may be, a series of supports have been knocked from under you, followed by a feeling of frustration. When suffering from culture shock people first reject the environment which causes discomfort. The ways of the host country are bad Because they make us feel bad. When foreigners on a strange land get together to complain about the host country and its people, you can be sure that they are suffering from culture shock.

According to the passage, culture shock is______.

A．an occupational disease of foreign people

B．may lead to very serious symptoms

C．actually not a disease

D．incurable

What is your favorite color？ Do you like yellow, orange, and red？ If you do, you must

be an optimist (乐观者), a leader, and an active person who enjoys life, people and excitement.Do you prefer grays and blues？ Then you are probably quiet, shy and you would rather follow than lead.You tend to be a pessimist.At least, this is what psychologists (心理学家)tell us, and they should know, because they have been seriously study ing the meaning of color preference, as well as the effect that colors have on human beings.They tell us among other facts, that we do not choose our favorite color as we grow up — we are born with our preference.If you happen to love brown, you did so,as soon as you opened your eyes, or at least as soon as you could see clearly.

Color does influence our moods (情绪)― there is no doubt about it.A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress bri ngs warmth and cheer to the saddest winter day.On the other hand, black is depressing.A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area — until it was repainted green.The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

Light and bright colors make people not only happier but also more active.It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or gray.

1.The author regards the psychologists'findings as ().

A.groundless

B.doubtful

C.reasonable

D.unusual

2.According to the psycholog ists, a person’s color preference ().

B.is acquired through experience

C.is decided by his surroundings

D.is possessed from birth

3.It can be concluded from the passage that bright color lovers tend to be ().

A.quiet

B.active

C.depressive

D.pessimistic

4.The example of the bridge is used to illustrate that ().

A.people tend to kill themselves by jumping from bridges

B.color can affect people’s moods to a great degree

C.the bridge should have been repainted earlier

D.certain color can kill people sometimes

5.The notion that machines painted orange can reduce the risk of accidents ().

A.is a well-accepted fact

B.remains to be proved

C.is an illusion of workers

D.is a good wish of scientists

Animals other than humans have not developed communications comparable to human langua

ge. But is it possible that other animals have the capacity to learn a language if they are adequately taught？ Obviously, this is a fascination notion. The idea of communicating directly with another species has long been a part of human folklore and children’s fantasies. But on a scientific level, the question of whether animals can learn a language is important primarily because it relates to the controversy()between the cognitive and the learning approaches to language. If language is dependent on and is actually an outgrowth of the intellectual structure of the human mind, there is the strong supposition that only humans are capable of using language. Therefore, Noam Chomsky and other psycholinguists have argued that only humans can learn a language, while most behaviorists feel that with sufficient patience it should be possible to teach an animal some sort of language. Although the two schools of thought clearly differ on this point, it is not really a crucial test of the two theories. If a chimpanzee can master a simple language all it would mean is that the chimp’s intellectual capacity and brain structure are more similar to ours than we thought. It would not necessarily imply that our intellectual structure is unimportant in our own mastery of language. Thus, teaching an animal language is an impressive demonstration of the power of learning techniques, but it is not evidence that language is developed entirely through learning.On the other hand, the question of whether other animals can learn a language is fascination in its own right, aside from its value as a test of the two theories of language development. Accordingly, whatever one’s position on the theoretical dispute, we must consider training an animal to use language a dramatic accomplishment.

36.Which of the following statements is the view of psycholinguists？

A. The cognitive view of language learning says that only human beings can learn language because it is an outgrowth of the structure of the human mind.

B. Other animals simply could master a language.

C. The animals intellectual capacity is much better than human beings.

D. Language is developed by learning.

37.The behaviorists’ view is that __________.

A. language is actually an outgrowth of intellectual structure of the animal’s mind

B. animals have not developed communications system

C. given enough patience, a man should be able to teach an animal some sort of language

D. only human beings can learn language

38.That an animal can master a simple language means that __________.

A. human’s intellectual structure is not important

B. animals’ intellectual capacity and brain structure are more similar to the humans’

C. the learning techniques are much more important

D. language is developed completely by learning

39.The main idea of paragraph two is ___________.

A. teaching a chimp language is not crucial test of the two theories

B. their brain structure is not similar to human

C. using various methods to let the chimp master a language

D. training a nonhuman to use language is an amazing accomplishment

第11题

A moment's drilling by the dentist may make us nervous and upset.Many of us cannot

stand pain.To avoid the pain of a drilling that may last perhaps a minute or two, we demand the “needle”-a shot of Novocain (奴佛卡因) - that deadens the nerves around the tooth.

Now it's true that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it.This helps us adjust to the world.Without our nerves and our brain, which is a bundle of nerves, we wouldn't know what's happening.But we pay for our sensitivity.We can feel pain when the slightest thing is wrong with any part of our body.The history of torture is based on the human body being open to pain.

But there is a way to handle pain.Look at the Indian fakir (苦行僧) who sits on a bed of nails.Fakirs can put a needle right through an arm, and feel no pain.This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain.

The big thing in withstanding pain is our attitude towards it.If the dentist says, “This will hurt a little,” it helps us to accept the pain.By staying relaxed, and by treating the pain as an interesting sensation we can handle the pain without falling apart.After all, although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life.

26.The passage is mainly about().

A.how to suffer pain

B.how to avoid pain

C.how to handle pain

D.how to stop pain

27.Th e sentence “But we pay for our sensitivity.” in the second paragraph implies that ()

A.we should pay a debt for our feeling

B.we have to be hurt when we feel something

C.our pain is worth feeling

D.when we feel pain, we are suffering it

28.When the author mentions the Indian fakir, he suggests that().

A.Indians are not at all afraid of pain

B.people may be senseless of pain

C.some people are able to handle pain

D.fakirs have magic to put needles right through their arms

29.The most important thing to handle pain is ()

A.how we look at pain

B.to feel pain as much as possible

C.to show an interest in pain

D.to accept the pain reluctantly

30.The author's attitude towards pain is().

A.pessimistic

B.optimistic

C.radical

D.practical
