2008年12月大学英语四级考试全真模拟试题答案

Section B
　　Passage One
　　In the past, when a child swallowed poison, you were told to make the child vomit. Things are no longer that simple. New and different chemical poisons require different treatments. If your child swallows poison, it is a good idea to call Poison Control or your doctor immediately. If you go to the hospital, be sure to take the bottle of medicine. (or chemicals ) with you.

    What about those small accidents that happened every day： the stove burns， the knife cuts， and the scraped knees？ You can‘t always run to the doctor.

    The first thing to do is to decide if the injury is serious enough to go to the hospital. If it is， go right away. Don‘t wait until morning or wait for a few hours to see how you feel. If the injury is serious， go to the hospital immediately.

    If you decide it isn‘t serious， there are many home remedies you can use. To treat small burns， for example， many people keep an aloe plant in the house. When they burn themselves， they rub the juice of the aloe leaf on the burn. The easiest thing to do is to run cold water on the burn. To heal cuts and scrapes， there are many things you can buy in the drugstore， such as antibiotic creams. But if you get a serious cut or are cut by something rusty， you should probably go to a doctor and get a tetanus shot.

　　Passage Two

　　Advertising is the tool that has always been used to convince the public to buy products. In the beginning, it was a basic and crude tool. Craftsmen cried out to passersby, telling the quality of their products. Today, newspapers, magazines, radio, and television use a variety of means to introduce the public to the many products developed through technology.

The Romans started using recorded advertisements. They smoothed and whitened areas on a wall where advertisements could be written or carved.

　　In the Middle Ages, people continued to use verbal announcements and written messages, but a new form of advertising, using symbols, was developed as well. Shops displayed a special symbol to indicate what goods or services could be found inside.

　　The Industrial Revolution caused an explosion in the advertising field. The abundance of luxury goods, coming both from new inventions and from trade with different parts of the world, meant that consumers had to be told more about products than ever before. They had to be persuaded that they needed all these new products and that one product was superior to its many competitors. The buying public was soon being exposed to endless amounts of advertising.

　　Passage Three

    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 or take it as true 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.

　　33. What is the reason for believing that future man will be different?

　　34. Why will people‘s heads eventually grow larger？

　　35. How many main changes concerning human body will there be in the future?

    33. 答案：B

    解析：细节题。从原文“For man is slowly changing all the time.”可以得出正确答案。

    34. 答案：B

    解析：细节题。文中说：人类越来越多地使用大脑，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. 该句中的bring about 说明了前因后果的关系。

    35. 答案：D

    解析：判断题。文中提到人类在未来身高、大脑和眼睛的变化，所以D三个方面的变化为正确答案。
