听力原文： America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect American society in many ways — education, medicine and business.

Quietly, the graying of America has made us a very different society — one in which people have a quite different idea of what kind of behavior. is suitable at various ages. A person's age no longer tells you anything about his / her social position, marriage or health. There's no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn't as strong as it used to be. It doesn't surprise us to hear of a 29-year-old university president or a 35-year-old grandmother, or a 70-year-old man who has become a father for the first time.

Public ideas are changing. Many people say, "I am much younger than my mother or my father was at my age". No one says "Act your age" anymore. We've stopped looking with surprise at older people who act in youthful ways.

Questions 29 to 31 are based on the passage you have just heard.

29. What is the percentage of people above 65 in America today？

30. What can we know from the passage？

31. What does the passage imply？

(30)

A．4%.

B．10%.

C．14%.

D．25%.

听力原文： According to Alvin Toffler, author of the best seller Future Shock, （32)America

听力原文： According to Alvin Toffler, author of the best seller Future Shock, (32)America has become a throwaway society. (33)Cardboard milk containers and rockets are only two examples. Such products are created for short-term or one-time use. They are becoming more numerous and more important to modern living. Toffler thinks that man's relationships with things will grow increasingly temporary.

As proof of this trend, Toffler cites such products as disposable diapers, (33)bibs, paper napkins and non-returnable bottles. Vegetables are encased in plastic sacks. They can be dropped into a pan of boiling water and thrown away after the meal. TV dinners are cooked in throwaway trays. They are even served in them.

All these things are quickly used up. Then they are ruthlessly eliminated. In Toffler's view, the American home has become little more than a large processing plant.

(35)Toffler further believes that his countrymen are developing values to go with their throwaway products. (34)He says that easy disposability leads to shorter man-thing relationships. People were once linked with a few objects for a long time. Now they are linked with a series of objects for a brief period. So the relationship between them is not so long and it's hard for people to have the deep feeling to something. Because after one time. they'll be thrown away.

(33)

A．Introduce Alvin Toffler's best seller Future Shock.

B．Discuss the throwaway problem in America.

C．Analyze the relationship between men and things.

D．Describe the throwaway products made in USA.

听力原文：Unless you have visited the southern United States, you probably have never heard

听力原文： Unless you have visited the southern United States, you probably have never heard of Kudzu. Kudzu, as any farmer in the south will sadly tell you, is a superpowered weed. It is a strong climbing plant. Once it gets started, Kudzu is almost impossible to stop. It climbs to the tops of the tallest trees. It can cover large buildings. Whole barns and farm houses have been known to disappear from view. Wherever it grows, its thick twisting stems are extremely hard to remove. Kudzu was once thought to be a helpful plant. Originally found in Asia, it was brought to America to help protect the land from being swallowed by the sea. It was planted where its tough roots which grow up to five feet long could help hold back the soil. But the plant soon spread to places where it wasn't wanted. Farmers now have to fight to keep it from killing other plants. In a way, Kudzu is a sign of labor shortage in the south. Where there is no one to work the fields, Kudzu soon takes over. The northern United States faces no threat from Kudzu. Harsh winters kill it off. The plant loves the warmth of the south, but the south surely doesn't love it. If someone could invent some use for Kudzu and remove it from southern farmland, his or her fortune would be assured.

(23)

A．It has done more harm than good in the southern USA.

B．It was brought to the northern USA by Asian farmers.

C．It was introduced into the USA to kill harmful weeds.

D．It can be used by farmers to protect large buildings.

听力原文： "But I just paid $1.69 for this bottle of wine last week. How come the price is now $2.25？ What's going on？"

There are at least three things going on that have caused the price of wine to rise. All have to do with the supply and demand factors of economics.

The first factor is that people are drinking more wine than ever before. This demand for more wine has increased overall wine sales in America at the rate of 15 percent a year.

The second factor is that the supply of wine has stayed relatively the same, which means that the same number of bottles is produced each year. Wine producers are trying to open up new land to grow more grapes. But in at least three wine-producing areas of the world France, Germany, and California new vineyards will not be available in the near future. Wines are produced in other countries, such as Italy, Spain and Australia, but none of these countries will be able to fill the demand for good wines.

The third factor is that costs of wine production are increasing. The men who make wine are asking for more money, and the machinery needed to press the grapes is becoming more expensive.

When the demand for something is greater than the supply, prices go up. When production costs, meaning the price of labor and machinery, rise, the producer adds this increase to the price of the wine.

(33)

A．The speaker is inquiring about the price.

B．The speaker is concerned about the price.

C．The speaker is bargaining with the dealer.

D．The speaker is complaining about the price.

听力原文： What will man be like in the future--in 5,000 or even 50,000 years from now.'？ We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more--and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modem life.

(30)

A．Future man's life style.

B．Future man's thoughts.

C．Future man's appearance.

D．Future man's education.

听力原文：Did you know that vegetables can be tricked into growing in climates they are not

听力原文： Did you know that vegetables can be tricked into growing in climates they are not accustomed to？ Cool climate vegetables like asparagus are now able to be grown in places as hot as Hawaii. In Hawaii marine engineers have been able to actually convince such vegetables that they're in cooler climates. That way they grow faster and taste better. What these engineers have been using is very simply cold water. How do they use it？ They place pipes in the soil and the cold water flows in through and then cools the air. This stimulates plant growth and enables gardeners in tropical climates to grow crops from cooler climates. Also some of these pipes are exposed to the air and they condense moisture and thus irrigate the garden. What's especially appealing about this process is that nothing damaging to the environment is being used. Another innovative use for cold ocean water is to cool buildings. Engineers believe that, for example, the entire western coast of the United States could be air-conditioned using seawater. We'll be back to discuss that possibility after this commercial message.

(26)

A．Irrigating desert areas.

B．Use for cold seawater.

C．Techniques for preserving the environment.

D．The importance of conserving energy.
