三、阅读理解（本大题共15小题，每小题2分，共30分）
Passage 1
Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school.
Parents are concerned about the lack of quality in television programs for children. The degree of violence in many of these shows also worries them. Studies indicate that, when children are exposed to violence, they may become aggressive or insecure.
Parents are also concerned about the commercials (商业广告) that their children see on television. Many parents would like to see fewer commercials during programs for children. And some parents feel that these shows should not have any commercials at all because young minds are not mature enough to deal with the claims made by advertisers.
Educational television has no commercials and has programs for children that many parents approve of. The most famous of these is Sesame Street, which tries to give preschool children a head start in learning the alphabet (字母) and numbers. It also tries to teach children useful things about the world in which they live.
Even though most parents and educators give Sesame Street and shows like it high marks for quality, some critics argue that all television, whether educational or not, is harmful to children. These critics feel that the habit of watching hours of television every day turns children into bored and passive (被动的) consumers of their world rather than encouraging them to become active explorers of it.

A．Parents are worried about the influence from television on their children.
B．Television has much influence on children.

A．They become the victims of social violence.

A．they think that their children are not old enough to handle advertising
B．commercials teach children alphabet and numbers
C．commercials help to sell products

29．Educational television is widely appreciated because ______D_______.
A．it does have the same commercials as others
B．it offers programs for both children and their parents
C．many parents like the programs it offers for their children
D．children can learn some school subjects before they go to school

Passage 2
    What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
        Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity (容量). As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger.
        Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger.
        On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
        But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
        Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own.
31. The size of man’s forehead will probably grow bigger because ____A___.
A. he will use his brain more and more as time goes on
B. he makes use only 20% of the brain’s capacity
C. his brain has grown larger over the past centuries
D. the other 80% of his brain will grow in due time       
32. What serves as the evidence that man is changing?B
A. Man has got stronger eyes now than he ever had.
B. Man has been growing taller over the past 500 years.
C. Man’s hair is getting thinner and thinner.
D. Man’s arms and legs have become lighter and weaker.
33. What will be true about a human being in the future?A
A. He will be hairless because hair is no longer useful.
B. He will have smaller eyes and will wear better glasses.
C. His fingers will grow weaker because he won’t have to make use of them.
D. He will think and feel in a different way.
34. It is implied that __________B________.
A. human beings will become more attractive in the future
B. body organs will become poorer if they are not used often
C. human beings hope for a change in the future life
D. future life is always predictable
35. The passage mainly tells us that ______C_________.
A. man’s life will be different in the future
B. man is growing taller and uglier as time passes
C. future man will look quite different from us
D. human beings’ organs will function weaker

Passage 3
Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labor through your work, you may say that you’re “hot”. That’s true. The time of day when you feel most energetic (精力充沛) is when your cycle of body temperature is at its peak. For some people the peak comes before noon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar sayings as: “Get up, John! You’re late for work again!” The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can’t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won’t change your cycle, but you’ll work better at your low point.
Get off to a slow start which saves your energy. When you get up, sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.
36. According to the new findings of Dr. Kleitman, if a person finds getting up early a problem, most probably ______D____________.
A. he is a lazy person
B. he refuses to follow his own energy cycle
C. he is not sure when his energy is low
D. he is at his energy peak in the afternoon or evening
37. Which of the following may lead to family quarrels according to the passage?A
A. Unawareness of energy cycles.
B. Familiar saying.
C. A change in a family member’s energy cycle.
D. Attempts to control the energy cycle of other family members.
38. If one wants to work more efficiently at his low point in the morning, he should __C_______.
A. change his energy cycle                                        B. overcome his laziness
C. get up earlier than usual                                        D. go to bed earlier
39. You are advised to act slow when you rise in the morning because it will _____A_______.
A. help to keep your energy for the day’s work               
B. help you to control your mood early in the day
C. enable you to concentrate on your routine work       
D. keep your energy cycle under control all day
40. Which of the following statements is NOT true?B
A. Getting off to work with a minimum effort helps save one’s energy.
B. Dr. Kleitman explains why people reach their peak at different hours of day.
C. Habit helps one adapt to his own energy cycle.
D. Children have energy cycles, too.
