听力原文: A few months ago, [32] a team of interviewers were sent to schools to find out why children are prejudiced against science. Their answer provided this surprising picture of a typical scientist: they thought [33] a scientist is a rather dull person who spends all day working in a laboratory, wearing a white coat and making things that smell bad. They thought that scientists usually aren't very interesting and don't talk about anything but science. They don't play games well and they aren't attractive to the opposite sex. They also did not realize that women are as capable of becoming scientists as men.
On the other hand, [34] an art graduate is seen as a much livelier person. Arts graduates are thought to have a better sense of humor, to be interested in sports and pop music and to be considered attractive. When you understand these misconceptions which children have, it is only logical that most of them want to study arts rather than science.

At the beginning of this century, almost everybody believed in work. But by the end of this century, e might be thinking quite differently. Today, people are divided into social classes in accordance with the types of work they do; tomorrow, t is more than likely we will be divided according to the types of games we play.
This change in the use of our time may give rise to a now profession called" fun specialists," who will fill the same functions as our current career specialists. They will show us how to get the most fun and enjoyment out of our leisure time. Someday people will no longer be known primarily by the work they do.

SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文: Various kinds of nuclear weapons have been produced in the past few years by many countries. This is a new and a terrible development in the history of man. Very few events can be more frightful than a nuclear war. In a nuclear war, most of the world's population will be exterminated. (15[C])The few living Creatures that survive will be exposed to radiation or to electrical rays harmful to life. It has been said by scientists that many new diseases will be caused by radiation. (16[B])There will also be an acute shortage of food, for all the crops and stores will be poisoned by radiation. Most of the areas on which nuclear bombs have been dropped will be ruined. (17[A])Therefore the survivors of a nuclear war will be sick, hungry and homeless. It might be better; perhaps, to be killed in a nuclear war than to survive it. It would be better still for men to learn to live in peace with one another. If this can be achieved there will be no nuclear wars.
If nuclear bombs are dropped on an area the survivors will ______.
A.hide in their houses
B.store more food
C.be very sick
D.grow more crops
听力原文: No one knows exactly why we sleep. But scientists have learned a lot about how we sleep, From sleep experiments, scientists have learned that there are four different stages of sleep.
When you first fall asleep, your heart starts to beat more slowly and your breathing slows down. If something wakes you, you might not think that you had been asleep. Some people call this kind of sleep dozing. Scientists call it Stage One sleep. Next, if you are not awakened, you drift into a deeper sleep. Your pulse and breathing become even slower than they were during Stage One sleep. But you can still be awakened quite easily. If you take a cat nap, you probably will not get any further than this stage of sleep, which is called Stage Two.
If you sleep longer than about twenty minutes, you go into the third stage of sleep. Your body is very relaxed. It would take a loud noise to wake you up.
You have probably heard of people who walk in their sleep. No one knows what makes people sleepwalk. But a person can sleepwalk only during Stage Four. This is the deepest kind of sleep. If someone wakes you up during stage four, you might feel very confused. It might take you a few minutes to get used to being awake.

A.Reasons for People's Sleeping.
B.Four Stages of Sleep.
C.Reasons for sleepwalking.
