9、swer the questions below each text by choosing A, B, C or D. (40 points) 21 You might be forgiven for thinking that sleep researchers are a dozy bunch. Most of the other things people do regularly eat, excrete, copulate and so on are biologically fairly straightforward: there is little mystery about
10、 how or why they are done. Sleep, on the other hand, which takes up more of most peoples time than all of the above, and which attracts plenty of study, is still fundamentally a mystery. The one view shared by all is that sleep matters. For evidence, look no further than the experiments led by Allan
11、 Rechtaschaffen and Bernard Bergmann at the University of Chicago in the 1980s. They kept experimental rats awake around the clock in an environment where control rats were allowed as much sleep as they wanted. The sleep-deprived rats all died within a month. Carol Everson worked with the Chicago te
12、am as a graduate student and now has a job at the National Institutes of Health in Bethesda, Maryland. While repeating the Chicago experiments she was struck by the fact that, although the sleep-deprived rats showed no obvious symptoms of particular diseases and no such signs were picked up in post-
13、mortems their emaciation and generally sorry state was reminiscent of that which befalls many terminal cancer patients and AIDS patients, whose immune systems have packed up. While Dr. Everson does not claim to have hard and fast proof that sleep is needed for resistance to infection, her work does
14、point that way as does the re search of others around the world. Another approach is to look for chemicals that cause sleep; from these, you should be able to start telling a biological story which will eventually reveal the function of sleep. Peter Shiromani of Harvard Medical School has found a pr
15、otein that builds up at high levels in chronically sleep-deprived cats, but disappears within an hour if the animals are allowed 45 minutes of recovery sleep. Researchers at the University of Veron have found something similar. But no one chemical tells the whole story. So new ways of inducing sleep
16、 may soon be available; an understanding of its purpose, though, remains elusive. In this, sleep is like the other great biological commonplace that is still mysterious: consciousness, which is also easily altered chemically but not too well under stood. No one knows how Consciousness arises, or wha
17、t, if anything, it is for(though there are a lot of theories). Almost the only thing that can be said about it for certain is that you lose it when you fall asleep. Solving the mystery of sleeping and waking might require new insights into the consciousness that is lost and regained in the process.
18、Putting it this way makes the problem sound rather grander, and the lack of progress so far look a bit less dozy. 21 Why does the writer say “You might be forgiven for thinking that.“? ( A) Solving the mystery of sleeping and waking requires new insights. ( B) Most of the other things people do regu
19、larly are biologically straightforward. ( C) The problem sounds rather grand. ( D) We still lack for progress though weve spent much more time studying it. 22 The experiments led by Allan Rechtaschaffen and Bernard Bergmann at the University of Chicago _. ( A) couldnt prove that sleep matters ( B) a
20、llowed the control rats as much sleep as possible ( C) showed that sleep is still fundamentally mystery ( D) kept the experimental rats up all day and all night 23 Which of the following statements is NOT true according to the passage? ( A) Dr. Everson announced the conclusion of the experiments tha
21、t sleep is needed for resistance to infection. ( B) Carol Everson repeated the experiments led by Allan Rechtaschaffen and Bernard Bergmann at the University of Chicago. ( C) Carol has been a graduate student at the University of Chicago. ( D) Carols later experiment found some similarities between
22、sleep-deprived rates and many terminal cancer patients and AIDS patients. 24 The protein found by Peter Shiromani _. ( A) eventually revealed the function o? sleep ( B) built up at high levels in chronically sleep-deprived rats ( C) was similar to that found by researchers at the University of Veron
23、 ( D) lasted for only 45 minutes 25 The writer seems to think that _. ( A) new ways of inducing sleep is still beyond mans knowledge ( B) consciousness is a crucial part in sleep research ( C) the understanding of the purpose of sleep is still hard to achieve ( D) weve got new insights into the cons
24、ciousness 26 Einsteins connection with the politics of the nuclear bomb is well known: he signed the famous letter to President Franklin Roosevelt that persuaded the United States to take the idea seriously, and he engaged in postwar efforts to prevent nuclear war. But these were not just the isolat
