It is possible that the weather of the world may be changing. Some scientists imagine that

this could even mean the beginning of another ice age. The effects of such a change in weather on human population of the world would be frightening.

Recent research suggests that the warming trend (倾向) of the past hundred years or so may be coming to an end. During the past ten years, scientists tell us that the temperature of the world has dropped a little. This would have effects on wind and rain in the weather picture.

Scientists believe clouds may be an important factor (因素) in changing the amount of heat on the earth. Another possibility is that man's agriculture and industry ways may affect the natural weather.

The weather of the world seems to be getting ______.

A．hotter

B．colder

C．warmer

One of the most authoritative voices speaking to us today is, of course, the voice of the

advertisers. It shouts at us from the television screen and the radio loudspeakers; waves to us from every page of the newspaper; signals to us from the roadside bill-boards all day and flashes messages to us in colored lights all night.

Advertising has been among England's biggest growth industries since the war. Perhaps the reason is that advertising saves the manufacturers from having to think about the customer.

At the stage of designing and developing a product, there is quite enough to think about without worrying over whether anybody will want to buy it. The designer is busy enough without adding customer-appeal to all his other problems of man-hours and machine tolerance and stress factors. So they just go ahead and make the thing and leave it to the advertiser to find clever ways of making it appeal to purchasers after they have finished it, by pretending that it confers(赋予) status, or attracts love, or signifies manliness.

Other manufacturers find advertising saves them from changing their product. And manufacturers hate change. The ideal product is one that goes on unchanged forever. If, therefore, for one reason or another, some alteration seems called for—how much better to change the image, the packet or the pitch made by the product, rather than go to all the inconvenience of changing the product itself.

Which of the following can best describe the author's attitude toward modern advertising？

A．Indifferent.

B．Shocked.

C．Disappearing.

D．Approving.

Our environment is getting worse and worse with the increase of the world population, whic

h affects the environment in two ways. Firstly, the limited energy resources will be used up much faster. Secondly, the increasing population creates more pollution, another severe problem that needs to be solved: Both problems are long-term ones because actions taken now show their results slowly over many years. They are also urgent because delays in action can lead to great suffering and social problems. The question seems to be difficult to handle for most people. However, a person can be a protector of environment in everyday life if he takes actions to save the environment right now. With the development of technology, cars make transportation easier and quicker than before, but we can't ignore the disadvantages brought to us by more and more cars in use. For example, we are consuming gasoline(汽油), which is a non-renewable (无法更新的)resource, and will soon be gone. Moreover, the exhausted gas from cars pollutes our air, and our health is therefore threatened by air pollution, which has a big potential effect on our daily life. So we can consider walking, taking buses, carpooling(合用汽车) instead of driving cars alone. This seems to be a very slow process that can't be so effective if it's taken by a single person. But when more and more people become aware of the importance and positively take it as their personal responsibilities, the condition of the air will be improved to a great extent.

According to the writer, the main problem to our environment today is______.

A．the increase of population

B．the limited energy resources

C．the more serious air pollution

D．the development of technology

To us it seems so natural to put up an umbrella to keep the water off when it rains. But a

ctually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun!

Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, as early as the eleventh century B. C.

We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honour and authority. In the Far East in ancient times the umbrella was allowed to be used only by royalty or by those in high office.

In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.

During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared a gain in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. By 1680, the umbrella appeared in France, and later on in England.

By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style. during all this time, though they have become much lighter in weight. It wasn' t until the twentieth century that women' s umbrellas began to be made, in a whole variety of colours.

According to this passage, the umbrella was probably first invented ______.

A．in ancient China

B．in ancient Egypt

C．in ancient Greece

D．in ancient Rome

Everyone seems to be in favor of progress. But " progress" is a funny word. It doesn't nec

essarily mean that something has become stronger, wiser, or better. It simply means changing it from being one thing to another and sometimes it turns out to be worse than before.

Consider medicine, for instance. No one can deny that medical progress has enriched our lives tremendously. Because of medical advances, we eat better, live easier and are able to take care of ourselves more efficiently. We can cure disease with no more than one injection or a pill. If we have a serious accident, surgeons can put us back together again. If we are born with something defective, they can repair it. They can make us happy, restore our normality, ease our pain, replace worn parts and give us children. They can even bring us back from the dead. These are wonderful achievements, but there is a price we have to pay.

Because medicine has reduced infant mortality and natural death so significantly, the population has been rising steadily, in spite of serious efforts to reduce the rate of population growth. Less than a century ago in the United Stales, infant mortality claimed more than half of the newborn within the first year of life. Medical advances, however, have now reduced that rate to nearly zero. A child born in the United States today has better than a 90% chance of survival. Furthermore, medical advances have ensured that most of these infants will live to be seventy years of age or more, and even that life expectancy increases every year. The result of this progress is an enormous population increase that threatens the quality of life, brought about by progress in the medical profession.

According to this passage, " progress" doesn't always mean that______.

A．something has become stronger and better

B．something has been changed from being one thing to another

C．something has become funny

D．something turns out to be worse than before

听力原文： All right! Enough cookies, cola, and chips! It seems that junk food is all that the children want to eat these days.Television controls their tastes. The kids see well-known personalities eating potato chips, candy, and other processed food, and they want to be like their heroes. How do they do it？ They eat the same food. I wish there were more characters like old Popeye the sailor, who ate spinach and not French fries.

Just because I like brown rice, beans, and fresh vegetables, I don't expect my children to cat this "health food." I'm glad to cook traditional meals of meat and potato for them. I really can't be too upset with the kids because most adults aren't careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can't eat hot dogs, with all those preservatives, and hamburgers are filled with chemicals so that they look good. Besides the meat, they had sugar filled cookies and cake, and, of course, chips. Terrible! I don't want the world to change because of me, but I think that people should realize that there are alternatives to eating meat. They always tell me that I probably don't get my essential proteins. But I feel better than ever and I'm sure that it's because I'm vegetarian. I would really like to see more television advertisements which show the benefits of good, healthy, natural food.

(26)

A．Beans.

B．Cookies.

C．French fries.

D．Potato chips.
