1、大学英语六级阅读理解真题及答案12021年1月大学英语六级阅读理解真题及答案Questions 21 to 25 are based on the following passage.There are desert plants which survive the dry season in the form of inactive seeds. There are also desert insects which survive as inactive larvae (幼虫). In addition, difficult as it is to believe, there are d

2、esert fish which can survive through years of drought (干旱) in the form of inactive eggs. These are the shrimps (小虾) that live in the Mojave Desert, an intensely dry region in the south-west of the United States where shade temperatures of over 50C are often recorded.The eggs of the Mojave shrimps ar

3、e the size and have the appearance of grains of sand. When sufficient spring rain falls to form a lake, once every two to five years, these eggs hatch (孵化). Then the water is soon filled with millions of tiny shrimps about a millimetre long which feed on tiny plant and animal organisms which also gr

4、ow in the temporary desert lake. Within a week, the shrimps grow from their original 1 millimetre to a length of about 1.5 centimetres.Throughout the time that the shrimps are rapidly maturing, the water in the lake equally rapidly evaporates. Therefore, for the shrimps it is a race against time. By

5、 the twelfth day, however, when they are about 3 centimetre long, hundreds of tiny eggs form on the underbodies of the females. Usually by this time, all that remains of the lake is a large, muddy patch of wet soil. On the thirteenth day and the next, during the final hours of their brief lives, the

6、 shrimps lay their eggs in the mud. Then, having ensured that their species will survive, the shrimps die as the last of the water evaporates.If sufficient rain falls the next year to form another lake, the eggs hatch, and once again the shrimps pass rapidly through their cycle of growth, adulthood,

7、 egg-laying, and death. Some years there is insufficient rain to form a lake: in this case, the eggs will remain dormant for another years, or even longer if necessary. Very, very occasionally, perhaps twice in a hundred years, sufficient rain falls to form a deep lake that lasts a month or more. In

8、 this case, the species passes through two cycles of growth, egg-laying, and death. Thus, on such occasions, the species multiplies considerably, which further ensures its survival.21. Which of the following is the MOST distinctive feature of Mojave shrimps?A) Their lives are brief.B) They feed on p

9、lant and animal organisms.C) Their eggs can survive years of drought.D) They lay their eggs in the mud.22. By saying “for the shrimps it is a race against time” (Para. 3, line 2) the author means _.A) they have to swim fast to avoid danger in the rapidly evaporating lakeB) they have to swim fast to

10、catch the animal organisms on which they surviveC) they have to multiply as many as possible within thirteen daysD) they have to complete their life cycle within a short span of time permitted by the environment23. The passage mainly deals with _.A) the life span of the Mojave shrimpsB) the survival

11、 of desert shrimpsC) the importance of water to lifeD) life in the Mojave Desert24. The word “dormant” (Para. 4, Line 3) most probably means _.A) inactiveB) strongC) alertD) soft25. It may be inferred from the passage that _.A) appearance and size are most important for life to survive in the desert

12、B) a species must be able to multiply quickly in order to surviveC) for some species one life cycle in a year is enough to survive the desert droughtD) some species develop a unique life pattern to survive in extremely harsh conditionsQuestions 26 to 30 are based on the following passage.Opportuniti

13、es for rewarding work become fewer for both men and women as they grow older. After age 40, job hunting becomes even more difficult. Many workers stay at jobs they are too old for rather than face possible rejection. Our youth-oriented, throw-away culture sees little value in older people. In writer

14、 Lilian Hellmans words, they have “the wisdom that comes with age that we cant make use of. “Unemployment and economic need for work is higher among older women, especially minorities, than among younger white women. A national council reports these findings: though unemployed longer when seeking wo

15、rk, older women job-hunt harder, hold a job longer with less absenteeism (缺勤), perform as well or better, are more reliable, and are more willing to learn than men or younger women. Yet many older women earn poor pay and face a future of poverty in their retirement years. When “sexism meets ageism,

16、poverty is no longer on the doorstep it moves in,” according to Tish Sommers, director of a special study on older women for the National Organization for Women.Yet a 1981 report on the White House Conference on Aging shows that as a group, older Americans are the “wealthiest, best fed, best housed,

17、 healthiest, most self-reliant older population in our history. “This statement is small comfort to those living below the poverty line, but it does explode some of the old traditional beliefs and fears. Opportunities for moving in and up in a large company may shrink but many older people begin suc

18、cessful small businesses, volunteer in satisfying activities, and stay active for many years. They have few role models because in previous generations the life span was much shorter and expectations of life were fewer. They are ploughing new ground.Employers are beginning to recognize that the matu

Nothing can exceed the joy of discovering for yourself something that is important to you! It may be an idea or a bit

25、of information you come across accidentallyor a sudden insight, fitting together pieces of information or working through a problem. Such personal encounters are the “payoff” in education. A teacher may direct you to learning and even encourage you in itbut no teacher can make the excitement or the

26、joy happen. Thats up to you.A research paper, assigned in a course and perhaps checked at various stages by an instructor, leads you beyond classroom, beyond the texts for classes and into a process where the joy of discovery and learning can come to you many times. Preparing the research paper is a

27、n active and individual process, and ideal learning process. It provides a structure within which you can make exciting discoveries, of knowledge and of self, that are basic to education. But the research paper also gives you a chance to individualize a school assignment, to suit a piece of work to

28、your own interests and abilities, to show others what you can do. Writing a research paper is more than just a classroom exercise. It is an experience in searching out, understanding and synthesizing, which forms the basis of many skills applicable to both academic and nonacademic tasks. It is, in t

29、he fullest sense, a discovering, an education. So, to produce a good research paper is both a useful and a thoroughly satisfying experience!To some, the thought of having to write an assigned number of pages, often more than ever produced before, is disconcerting. To others, the very idea of having

30、to work independently is threatening. But there is no need to approach the research paper assignment with anxiety, and nobody should view the research paper as an obstacle to overcome. Instead, consider it a goal to accomplish, a goal within reach if you use the help this book can give you.31. Accor
