冲刺100分单元优化练考卷系列答案Everyone knows that the Frenchmen are romantic, the Italians are fashionable and the Germans are serious. Are these just stereotypes or is there really such a thing as national character? And if there is, can it affect how a nation succeed or fail?
At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs (企业家) in the UK found that 70% felt that their efforts were not appreciated by the British public. Britain is hostile (敌意的) to success, they said. It has a culture of jealousy(嫉妒). 【小题1】 Jealousy is sometimes known as the “green – eyed monster” and the UK is its home.
Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people together and gave each an imaginary amount of money. 【小题2】 Those given a little were given the chance to destroy the large amount of money given to others – but at the cost of losing their own. Two thirds of the people tested agreed to do this.
【小题3】 . But there is also opposite evidence. The Organization for Economic Cooperation and Development recently reported that the UK is now the world’s fourth largest economy. That is not bad for people who are supposed to hate success. People in the UK also work longer hours than anyone else in Europe. So the British people are not lazy, either.
“It is not really success that the British dislike,” says Carey Cooper, a professor of management at the University of Manchester Institute of Science and Technology. “It’s people using their success in a way that seems proud or unfair or which separates them from their roots.”
【小题4】 They set out to do things in their way. They work long hours. By their own efforts they become millionaires. 【小题5】 . It hardly seems worth following their example. If they were more friendly, people would like them more. And more people want to be like them.
| A．This seems to prove that the entrepreneurs were right to complain. |
| B．The one who owns most money in the end is the winner. |
| C．As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood.” |
| D．It is not true that British people are born jealous of others` success. |
F. But instead of being happy they complain that nobody loves them.
G. Perhaps it is the entrepreneurs who are the problem.

Since early times, people have been ___41___with the idea of life existing somewhere else besides earth. Until recently, scientists believe that life on other planets was just a hopeful dream. But now they are beginning to___42____places where life could form. In 1997, they saw ____43____of planets near other stars like the sun. But scientists now think that life could be even nearer in our own solar system. One place scientists are studying very closely is Europa, a moon of Jupiter. Space probes(探测器) have provided evidence that Europa has a large ocean under its surface. The probes have also made scientists think that under its surface Europa has a rocky core（核心） giving off____44____heat. Water and heat from volcanic activity are two basic conditions needed for life to form. A third is certain basic____45____such as carbon, oxygen and nitrogen. Scientists believe there might be such chemicals lying at the bottom of Europa’s ocean. They may have already____46____life or may be about to. You may wonder if light is also needed for life to form. Until____47____, scientists thought that light was essential. But now, places have been found on earth that are in total blackness such as caves several miles beneath the surface. And bacteria,___48____ forms of life, have been seen there. So the lack of light in Europa’s sub-surface ocean doesn’t automatically rule out life____49____.
