au (凯亚巴布高原) of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead. The Kaibab had a storybook forest of largesized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, We, who have wandered through its forests and parks, have e to regard it as the most enchanting(迷人的) region it has ever been our privilege to visit. This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly. Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ ti me, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000. The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd, but a far greater loss resulted from starvation and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000. 32. The destruction of the environment of the Kaibab resulted from ________ .

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 ). 36 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. 37 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. 38 . 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.” 39 They set out to do things in their way. They work long hours. By their own efforts they bee millionaires. 40 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 plain. 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. E. Some were given a little, others a great deal. F. But instead of being happy they plain that nobody loves them。辽宁省葫芦岛市20xx_20xx学年高二英语上学期期中试题含解析
