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.
(33)
A．Scientists.
B．Art graduates.
C．Children.
D．Women.

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
(判断)AIDS, fifty years ago, didn’t exist.Fifteen years ago a few doctors and public health officials noticed the first cases.Within a few years it was clear that it has now killed almost 14 million people around the world.
Four years ago doctors came up with the first treatment to make a dent in the spiraling death rate.Today that treatment works for some patients, but it’s not clear how long results will last.And still there is no cure.
For the nearly 35 million people around the world now living with HIV, there may never be a cure.Once cells are infected with HIV, it is very difficult — perhaps impossible ―to rid them of the virus.The only sure way to stop AIDS is to prevent infection in the first place, and only a vaccine can do that.
Unfortunately HIV is one of the most changeable viruses known to science.After more than a dozen years, it is still rather difficult to produce effective vaccine.
Still the billions of dollars spent on AIDS research over the past 20 years has not been wasted.As scientists learn more about how HIV survives in the human body, they are realizing that drugs alone may not be enough.To contain the virus effectively, it may take a balance between drug treatments that can keep HIV levels low and a strengthened immune system that can then target and destroy the remaining virus.Until scientists find a vaccine, however, they may control but never cure the century’s final scourge.
46.AIDS didn’t exist fifteen years ago.
47.Scientists have found a vaccine which can prevent HIV infection.
48.Although some treatment works for some patients with HIV, there is still no cure.
49.HIV is a changeable virus so that it is very difficult to produce effective vaccine.
50.We have wasted billions of dollars on AIDS research.
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.
What do scientists tell us about jobs in foreseeable future？
A．Most people will do hi-tech jobs.
B．People will work with more computers.
C．Very few people will have to work.
D．No people will be working at all.
