题目列表(包括答案和解析)

阅读理解:

  Suppose we built a robot(机器人)to explore the planet Mars.We provide the robot with seeing detectors(探测器)to keep it away from danger.It is powered entirely by the sun.Should we program the robot to be equally active at all times?No.The robot would be using up energy at a time when it was not receiving any.So we would probably program it to stop its activity at night and to wake up at dawn the next morning.

  According to the evolutionary(进化的)theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason.The theory does not deny(否认)that sleep provides some important restorative functions(恢复功能).It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous.However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us.So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent.

  The evolutionary theory explains the differences in sleep among creatures.Why do eats, for instance, sleep so much, while horses sleep so little?Surely cats do not need five times as much repair and restoration as horses do.But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep.Horses must spend almost all their waking hours eating, because what they eat is very low in energy value.Moreover, they cannot afford to sleep too long or too deeply, because their survival(生存)depends on their ability to run away from attackers.

No country in the world has more daily newspapers than the USA. There are almost 2,000 of them, as compared with 180 in Japan, 164 in Argentina and 111 in Britain. The quality of some American papers is extremely high and their views are quoted all over the world. Famous dailies like the Washington Post or the New York Times have a powerful influence all over the country. However, they are not national newspapers in the sense that The Times is in Britain or Le Monde is in France, since each American city has its own daily newspaper. The best of these present detailed description of national and international news, but many tend to limit themselves to state or city news.

 Like the press in most other countries, American newspapers range from the “sensational” which feature crime and gossip(闲谈), to the “serious”, which focus on factual news and the analysis of world events. But with few exceptions, American newspapers try to entertain as well as give information, for they have to compete with the attraction of television.

 Just as American newspapers satisfy all tastes, so do they also try to attract readers of all political parties. A few newspapers support extremist(极端主义的) groups on the far right and on the far left, but most daily newspapers try to attract middle-of-the-road Americans who are moderate(中立的). Many of these papers print columns by well-known journalists of different political and social views, in order to present a balanced picture.

As in other countries, American newspapers can be either responsible or irresponsible, but it is generally accepted that the American press serves its country well and that it has more than once courageously exposed political scandals(丑闻) or crimes, for instance, the Watergate Affair(水门事件). The Newspapers drew the attention of the public to the horrors of the Vietnam War.

  A. Britain than in the USA.    B. France than in Britain

  A. supporting extremist groups from time to time

  B. inviting middle-of-the-road Americans to write articles for them
