听力原文： People in Poland take their pleasure seriously. They like to have an aim even when spending the time which is entirely their own. During the summer, people start work very early in the morning, so that they can finish early and enjoy a leisurely afternoon. It is difficult to imagine Polish people going aimlessly for a walk in the country, though they might go to pick wild fruit, to visit a place of historical importance or to walk 20 km as training exercise. They are often admired for their immense enjoyment of the arts. All their parks are beautifully cared for and are for the use and enjoyment of the people. Quite ordinary people will talk with obvious delight about concerts. There is nearly always a crowd at the door of the theatre, asking for returned tickets. People in Poland now have far more leisure time and more money than ever before. It is therefore possible to spend the weekends in many new ways. Many people now have over 20 vacation days per year. This provides an opportunity for holidays in the country or at the seaside.

(30)

A．They often go for walks at a leisurely pace.

B．They usually have a specific purpose in mind.

C．They like the seaside more than the countryside.

D．They seldom plan their leisure activities in advance.

听力原文：No one knows exactly how many disabled people there are in the world, but estimat

听力原文： No one knows exactly how many disabled people there are in the world, but estimates suggest the figure is over 450 million. The number of disabled people in India alone is probably more than double the total population of Canada.

In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people: as we get older, many of us will become less mobile, hard of hearing or have failing eyesight.

Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many progressive disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form. of a mental illness. All are affected by people's attitude towards them.

Disabled people face many physical barriers. Next time you go shopping imagine how you would manage if you could not get on to buses or trains. How would you cope if you could not hear the traffic？ But there are still other barriers: prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully understand what the severely disabled go through, so it is important to draw attention to these barriers and show that it is the individual personality and their ability, not their disability, which counts.

(26)

A．There are many disabled people in the world.

B．The number of disabled people in India is the greatest.

C．India has twice as many disabled people as in Canada.

D．It is impossible to get an exact figure of the world's disabled people.

听力原文： Some people hate everything that is modern. They cannot imagine how anyone can really like modern music; they find it hard to accept the new fashions in clothing; they think that all modern painting is ugly; and they seldom have a good word for the new buildings that are being built everywhere in the world. Such people look for perfection in everything, and they take their standards of perfection from the past. They are usually impatient with anyone who is brave enough to experiment with new materials or to express himself or the age in original ideas. It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures. If the work of art is a painting, the artist's failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing.

We can't judge every modern building by the standards of the ancient time, even though we admire the ancient buildings. Technologically, the modern buildings are more advanced. The modern architect knows he should learn from the ancient works, but with his greater resources of knowledge and materials, he will never be content to imitate the past. He is too proud to do that.

(30)

A．Because they are aged.

B．Because they find it hard to accept modern things.

C．Because they take their standards of perfection from the Greek.

D．Because they look at things by the standards of the past.

听力原文： Can you imagine ice that does not melt and is not wet？ Have your ever heard of dry ice？ Dry ice is made by freezing a gas. It is quite different from ordinary ice which is simply frozen water.

听力原文：Why do we cry？ Can you imagine life without tears？Not only do tears keep your eye

听力原文： Why do we cry？ Can you imagine life without tears？

Not only do tears keep your eyes lubricated, they also contain a substance that kills certain bacteria so they can't infect your eyes. Give up your tears and you lose this on-the-spot defence.

Nor would you want to give up the flood of extra tears you produce when you get something physical or chemical in your eyes. Tears are very good at washing this irritating stuff out.

Another thing you couldn't do without your tears is cry - from joy, anger, or sadness.

Humans are the only animals that produce tears in response to emotions. And most people say a good cry makes them feel better.

Many scientists, therefore, believe that crying somehow helps us cope with emotional situations. Tear researcher William Frey is trying to figure out how it happens.

One possibility, he says, is that tears discharge certain chemicals from your body, chemicals that build up during stress. "When people talk about 'crying it out,' I think that might actually be what they are doing," he says.

If Frey is right, what do you think will happen to people who restrain their tears？ Boys, for example, cry only about a quarter as often as girls once they reach their teenage years. And we all cry a lot less now than we did as babies.

Could it possibly be that we face less stress？ Maybe we've found other ways to deal with it. Or maybe we just feel embarrassed.

(33)

A．Why people hold back their tears.

B．Why people cry.

C．How to restrain one's tears.

D．How tears are produced.

Passage TwoAs we have seen, the focus of medical care in our society has been shifting fro

Passage Two

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease—especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious (有营养的) foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.

The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well.” In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well,” in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.

62. Today medical care is placing more stress on ________.

A) keeping people in a healthy physical condition

B) monitoring patients’ body functions

C) removing people’s bad living habits

D) ensuring people’s psychological well-being
