Images of our planet from outer space show vast oceans, lakes as big as small countries, and wide rivers flowing with incredible volume. How

3、 can there not be enough water? But the fact is that the world is facing the prospect of water shortages caused by population growth, uneven supplies of water, pollution, and other factors. The United Nations predicts that water shortages could hinder the economic growth of some countries and lead t

4、o food shortages and, even possibly, to international conflicts. Is there enough water for everyone in the world? According to the U.N. Commission on Sustainable Development, humans currently use about half of the 12,500 cu km (立方千米) of water that is readily available from groundwater, rivers, and l

5、akes. So by a simple measure of liters and gallons, there is enough water to quench (结束) the thirst of every creature and plant, every field, and every industry now existing. But water remains a fixed resource. “Given an expected population increase of about 50 percent in the next 50 years, coupled

6、with expected increases in demand as a result of economic growth and lifestyle changes, this does not leave much room for increased consumption,“ the U.N. commission said. A certain amount of water must be set aside to support the environment. Humans cannot drain the world“s lakes, rivers, and aquif

7、ers (蓄水层) without causing catastrophic (灾难性的) environmental damage. The world“s population has been growing enormously. The U.N. estimates that it will be over 9 billion by 2050. The amount of water available to each person decreases as the population grows, raising the possibility of water shortage

8、s. Water shortages will not come all at once in every part of the world. Just as the world“s population is unevenly distributed by region, so is the annual supply of renewable water. Rainfall and snowfall are determined by uneven weather patterns and landscape, and as a result, some areas of the wor

9、ld get more precipitation (降水量) than others.

15、he rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educated well

16、-off and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound. The world is facing an astonishing rise in the number of old people, and they will live longer th

17、an ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity (长寿) translated into more years in retirement rather than more years at work, has persuaded many obser

18、vers that this shift will lead to slower economic growth, while the swelling ranks of pensioners will create government budget problems. But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled. Employment

19、 rates are falling among younger unskilled people, whereas older skilled folk are working longer. The divide is most extreme in America, where well-educated baby-boomers (二战后生育高峰期出生的美国人) are putting off retirement while many less-skilled younger people have dropped out of the workforce. Policy is pa

20、rtly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Rising life expectancy (预期寿命), combined with the replacement of generous defined-benefit pension plans with less generous defined-contribution ones, means that even the better-off must

21、work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive than the preceding generation. T

22、echnological change may well reinforce that shift: The skills that complement computers, from management know how to creativity, do not necessarily decline with age.（分数：71.00）(1).What is happening in the workforce in rich countries?（分数：14.20）A.Younger people are replacing the elderly.B.Well-educated

23、 people tend to work longer.C.Unemployment rates are rising year after year.D.People with no college degree do not easily find work.(2).What has helped deepen the divide between the well-off and the poor?（分数：14.20）A.Longer life expectancies.B.A rapid technological advance.C.Profound changes in the w

24、orkforce.D.A growing number of the well-educated.(3).What do many observers predict in view of the experience of the 20th century?（分数：14.20）A.Economic growth will slow down.B.Government budgets will increase.C.More people will try to pursue higher education.D.There will be more competition in the jo

25、b market.(4).What is the result of policy changes in European countries?（分数：14.20）A.Unskilled workers may choose to retire early.B.More people have to receive in-service training.C.Even wealthy people must work longer to live comfortably in retirement.D.People may be able to enjoy generous defined-b

26、enefits from pension plans.(5).What is characteristic of work in the 21st century?（分数：14.20）A.Computers will do more complicated work.B.More will be taken by the educated young.C.Most jobs to be done will be creative ones.D.Skills are highly valued regardless of age.六、Part Translation(总题数：1，分数：10.00

27、)2.2010年，微电影(micro film)老男孩被贴在一个视频网站并大受欢迎。从此，微电影开始盛行。微电影的长度从 3分钟到半小时不等。成本低廉，拍摄过程简单，这使得很多草根艺人(grassroots artist)得以有机会来拍摄。人们喜欢在线观看电视节目的偏好也为微电影的发展提供了绝佳的机会。在这个快节奏的社会里，微电影正好可以解决人们没有太多时间来娱乐的问题。 （分数：10.00）_大学英语四级分类模拟题 525答案解析(总分：116.00，做题时间：90 分钟)一、Part Writing(总题数：1，分数：20.00)1.Directions: For this part, y

30、ving in a big family seems to be more enjoyable for them. Others, however, prefer to live by themselves. They cherish the idea to be independent, seek more freedom and have a place of their own, in which they can do whatever they like. Besides, they don“t want to be overprotected by their parents, a

31、nd they long for a chance to face the society by themselves. As for me, I like an independent life style in spite of the fact that I love my parents. Living separately, every generation can enjoy different life styles. In addition, by living an independent life, I can develop an ability to deal with

32、 things happening in my life and build up confidence that I can manage my own life well.二、Part Reading Compr(总题数：0，分数：0.00)四、Passage One(总题数：1，分数：15.00)Water shortages on planet Earth?

D.To present the beauty of the Earth and our love for it.解析：解析 第 1段以设问句开头，之后给出了这一问一答的具体阐释，展示了从太空拍摄的地球的照片，然后问怎么可能没有足够的水呢。可推知展示我们行星的照片是为了解释为什么地球上发生水

41、荒似乎是不可能的事情，故 C正确。该段第 3句提到从在太空中拍摄的地球的照片上看，地球上水资源很多，因此可排除 A和 B；D 在文中没有提及。(2).What result will water shortages bring according to the passage?（分数：3.00）A.It will lead to population growth and uneven supplies of water.B.It will make the present vast oceans become deserts.C.It will have serious consequenc

46、riting this passage?（分数：3.00）A.Water shortages have had serious effects on society.B.Water remains a fixed resource but the need for it continues increasing.C.The world has to deal with the problems arising from water shortages.D.The world is facing the danger of water shortages. 解析：解析 第 1段中就点明了本文的主
