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: Are you afraid, to raise your hand in class, even when you know the answer? If you are, most people would say that you are shy. If you feel shy, you are not alone. Nine out of ten people are at least a little shy. But however shy you are, scientific evidence seems to show that it isn't your fault. You may have been born that way.

How do psychologists measure shyness? One way is by observation. They keep detailed records of people's actions—like how often these people speak to others, or how long it takes someone to say "Hello" to a stranger. Another way to measure shyness is to ask people questions. The test only takes about 10 minutes. It asks question like "Do you like going out a lot?" and "Do you have many friends?" People must answer either "Yes" or "No". These questions can predict how people actually behave in social situations. Suppose the test tells you that someone is shy. Chances are good that person will act shy.

When scientists measure shyness, they are really comparing degrees of shyness. In other words, when researchers say people are shy, they really mean they are more shy than others.

(30)

A.Because many people don't know how to behave in social situations.

B.Because most people are shy by nature.

C.Nobody will laugh at you for being shy.

D.Shyness is difficult to overcome.

听力原文: Why do people smoke?

One reason is that people become addicted to cigarettes. The addictive substance in cigarettes is nicotine. When people smoke, the nicotine goes right into the blood stream and makes people feel relaxed. A smoker's body gets accustomed to the nicotine and if he stops smoking he feels nervous. Many smokers try to stop smoking but because of the addiction to nicotine they feel so uncomfortable that they often find it too difficult to stop.

Another reason is that people simply enjoy smoking. Having a cigarette for many people means taking a break. For some people smoking becomes part of their daily life. Many people enjoy smoking because it gives them something to do with their hands.

Many people also like the taste of tar in cigarettes. However, it is the tar that causes cancer. While governments and health experts have tried to get people to give up smoking entirely, cigarette manufacturers have tried to keep selling them by producing cigarettes with less tar. Many people in western countries have welcomed these cigarettes since they find it hard to stop smoking but they want to reduce the risk to their health.

(30)

A.Because they like the taste of tar.

B.Because smoking makes them feel relaxed.

C.Because smoking to them means fan.

D.Because smoking is the easiest thing to get addicted to.
