听力原文： Bicycling is one of the fastest growing forms of recreation. People are drawn to it for many reasons, being out in the fresh air, the thrill of speed, the physical challenge, along with many other things. But there can be many more uses for the bicycle, for example, transportation.

The use of bicycles can greatly improve the economy of a nation. A comparison between the efficiency of the transportation systems of the United Stated and Japan points this out. In 1990 Americans spent 17.9 percent of the GNP on transportation, whereas the Japanese spent only 10. 79 percent on transportation. This difference of nearly 7 percent, gives the Japanese economy much more money for investing in their future.

Our economy is not the only thing we should worry about, and it is also not the only thing that can be improved by the use of bicycles. There are several major problems that could be drastically reduced by the increased use of bicycles. Traffic would be a lot lighter due to the extremely small size of bicycles. It would also greatly reduce the wear and tear on our roads and highways, and therefore reduce government expenditure. But one of the most serious problems it would reduce is that of pollution and smog in our larger cities.

Bicycling, according to the speaker, is mainly a form. of______.

A．recreation

B．challenge

C．efficiency

D．transportation

听力原文： Do you have a tough math test coming up？ Then listen to some classical piano music just before the test. You might end up with a higher score (30) . Researchers at a university in California conducted an experiment. They asked a group of college students to listen to some piano music by a famous 18 th century composer before taking a math test. They were surprised to find that the students' scores jumped 8 to 9 points. The music seems to excite nerve activities in the brain (31) ; similar to the activity that occurs when a person is figuring out a math problem. However, the scientists warn that before you get too excited about applying this method to your math test, you should remember that brain-exciting effects lust only 10 to 15 minutes (32) . Would rock music work as well as the piano music do？ No, the scientists say. In fact, the less complex music might even interfere with the brains' reasoning ability.

(31)

A．How to improve your reasoning ability.

B．Why classical music is popular with math students.

C．The difference between classical music and rock music.

D．The effects of music on the results of math tests.

听力原文： Real policemen hardly recognize any resemblance between their lives and what they see on TV, if they ever get home on time. Of course, there are similarities, but the cops do not think much of them. The first difference is that a policeman's real life revolves around the law. Most of his training is in criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much as a professional lawyer, and what is more, he has to apply it in his feet, in the dark and rain, running down an alley after someone he wants to talk to. Little of his time is spent in chatting to almost naked ladies or in dramatic confrontations with desperate criminals. He will spend most of his working life typing millions of words on thousands of forms about hundreds of sad, unimportant people who are guilty of stupid, petty crimes. Most televise, on crime drama is a- bout finding the criminal; as soon as he is arrested, the story is over. In real life, finding criminals is seldom much of a problem. In fact, little effort is spent on searching.

A real policeman has to do all the following EXCEPT _______.

A．studying law

B．typing reports

C．talking to different people

D．chatting to naked ladies

听力原文： There are two main kinds of sports. The two kinds of sports are team sports and individual sports. Team sports are such sports as baseball, basketball and volleyball. Team sports require two separate teams. The teams play against each other. They compete against each other in order to get the best score. For example, in a football game if team A gets seven points and team B gets three points, team A wins the game. Team sports are sometimes called competitive sports. Besides team sports there is another main type or kind of sporting activity. The second type is individual sports. In individual sports there are no teams. There isn't any competition.

People play individual sports in order to get exercise. They don't play individual sports for the competition. Generally they want to get some exercise not to win a game. Individual sports are such sports as swimming; skiing and running. Of course it is possible to compete in individual sports. It is possible to keep a score in individual sports. The main difference, however, between team sports and individual sports is that individual sports can be performed alone.

Team sports always require more than one person.=

Why do people play team sports？

A．They play against each other in order to get the best score.

B．They want to get some exercises.

C．They want to win a game.

D．They want to keep a score.

听力原文： The Asian elephant is one of the world's rarest animals. Unfortunately, its sad condition has not been as well publicized as that of the African elephant. This is because Asian elephant's ivory supplies only a small percentage of the world ivory trade. In fact, we know very little about the Asian elephant. They live in the remote forests of southern Asia and it is therefore very difficult to study them. Most knowledge of Asian elephant is from those that have been captured or tamed. Asian elephants are easier to tame than African elephants. The elephants you see in the circuses and zoos are nearly always Asian.

The major reason for decline of Asian elephants is the harm to their forests. The huge increase in the human population has caused the destruction of the Asian forest. As a result, the Asian elephants are compelled to scatter in different areas. Originally they lived all over the continent, but now there are only small isolated populations left. These isolated elephant populations are vulnerable to extinction. While Asian elephants are threatened by illegal capture and detaining, they are also killed for ivory and skin. Elephants are shot in the forest along the border between Thailand and Burma, and their skin was sold to factories in Bangkok where the skins were made into shoes, belts, suitcases, wallets, etc., and then sold to tourists.

What's the difference between the Asian elephant and the African elephant？

A．The Asian elephant is easier to tame.

B．The Asian elephant's skin is more valuable.

C．The Asian elephant is less popular with tourists.

D．The Asian elephant produces ivory of a better quality.

听力原文： In ancient times, many people believed the earth was a flat disc. Well over 2,000 years ago, the ancient Greek philosophers were able to put forward two good arguments proving that it was not. Direct observation Of heavenly bodies was the basis of both these arguments. First, the Greeks knew that during eclipses of the moon, the earth was between the sun and the moon, and they saw that during these eclipses, the earth's shadow on the moon was always round, they realized that this could be true only if the earth was spherical. If the earth were a flat disc, then its shadow during eclipses would not be a perfect circle, it would be stretched out into a long ellipse. The second argument was based on what the Greeks saw during their travels. They noticed that the North Star, or Polaris, appeared lower in the sky when they traveled south, in more northerly regions, the North Star appeared to them to be much higher in the sky. By the way, it was also from this difference in the apparent position of the North Star that the Greeks first calculated the approximate distance around the circumference of the earth, a figure recorded in ancient documents says 400,000 stadia, that's the plural of the word stadium. Today, it's not known exactly what length one stadium represents, but let's say it was about 200 meters, the length of many athletic stadiums. This would make the Greek's estimate about twice the figure accepted today, a very good estimate for those writing so long before even the fast telescope was invented.

According to the professor, what were, the beliefs of the Greek philosophers based upon？

A．How the natural world was described in Greek mythology.

B．What they observed directly.

C．The writings of philosophers from other societies.

D．Measurements made with scientific instruments:
