Each passage is followed by some questions
2、 or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.Questions 21 to 25 are based on the following passage:We sometimes think human
3、s are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist(免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current
4、 by turning a wheel in their enclosure, while the other half could not. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the he
5、lpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has s
6、hown that animals who are allowed to control unpleasant stimuli dont develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can contro
7、l. Such findings reinforce psychologists suspicions that the experience or perception of helplessness is one of the most harmful factors in depression.One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the Un
8、iversity of Rochester School of Medicine conditioned(使形成条件反射) mice to avoid saccharin(糖精) by simultaneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice 新东方在线 C
9、ET6 通关班网络课堂电子教材系列 阅读2quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier
10、conditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.21. Laudenslagers experiment showed that the immune system of those rats who could turn off the electricity .A) was altered C
11、) was weakenedB) was strengthened D) was not affected 22. According to the passage, the experience of helplessness causes rats to .A) turn off the electricityB) try to control unpleasant stimuliC) become abnormally suspiciousD) behave passively in controllable situations23. The reason why the mice i
12、n Aders experiment avoided saccharin was that.A) they associated it with stomachachesB) it affected their immune systemsC) it led to stomach painsD) they disliked its taste24. The passage tells us that the most probable reason for the death of the mice in Aders experiment was that .A) the sweetener
13、was poisonous to themB) their immune systems had been altered by the mindC) they had been weakened psychologically by the saccharinD) they had taken too much sweetener during earlier conditioning25. It can be concluded from the passage that the immune systems of animals .A) can be altered by electri
14、c shocksB) can be weakened by conditioningC) can be suppressed by drug injectionsD) can be affected by frequent doses of saccharinQuestions 26 to 30 are based on the following passage:The destruction of our natural resources and contamination of our food supply continue to occur, largely because of
15、the extreme difficulty in affixing (把固定) legal responsibility on those who continue to treat our environment with reckless abandon (放任). Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been met by lawsuits, personal and industrial denial and long delays
16、not only in accepting responsibility, but more 新东方在线 CET6 通关班网络课堂电子教材系列 阅读3importantly, in doing something about it.It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is industrys and our recognition that protec
17、ting mankinds great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now.We are being asked, and, in fact, the public is demanding tha
18、t we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are pa
19、id to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge.We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-visioned in our app
20、roach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion.I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life
21、that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally sto
22、p environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.26. We can infer from the first two paragraphs that the industrialists disregard environmental protection chiefly because .A) it is difficult for them
23、 to take effective measuresB) time has not yet come for them to put due emphasis on itC) they are reluctant to sacrifice their own economic interestsD) they are unaware of the consequences of what they are doing27. The main task now facing ecologists, environmental activists and conservationists is
24、.A) to arouse public awareness of the importance of environmental protectionB) to prevent pollution by legislation, economic incentives and persuasionC) to improve the quality of life by enforcing environmental standardsD) to take radical measures to control environmental pollution28. The word “tunn
25、el-visioned”(Line 2, Para.4) most probably means “ ”.A) narrow-minded C) able to see only one aspectB) short-sighted D) blind to the facts29. Which of the following, according to the author, should play the leading role in the solution 新东方在线 CET6 通关班网络课堂电子教材系列 阅读4of environmental problems?A) The co
26、operation of ecologists, environmental activists and conservationists.B) The efforts of environmental health professionals.C) The industrys understanding and support.D) Legislation and government intervention.30. Which of the following is true according to the last paragraph?A) More money should be
27、spent in order to stop pollution.B) Environmental degradation will be stopped by the end of this decade.C) Ordinary citizens have no access to technical information on pollution.D) Efforts should be exerted on pollution prevention instead of on remedial measures.Questions 31 to 35 are based on the f
28、ollowing passage:British universities, groaning under the burden of a huge increase in student numbers, are warning that the tradition of a free education is at risk. The universities have threatened to impose an admission fee on students to plug a gap in revenue if the government does not act to im
29、prove their finances and scrap some public spending cutbacks.The government responded to the universities threat by setting up the most fundamental review of higher education for a generation, under a non-party troubleshooter(调停人), Sir Ron Dearing.One in three school-leavers enters higher education,
30、 five times the number when the last review took place thirty years ago.Everyone agrees a system that is feeling the strain after rapid expansion needs a lot more moneybut there is little hope of getting it from the taxpayer and not much scope for attracting more finance from business.Most colleges
31、believe students should contribute to tuition costs, something that is common elsewhere in the world but would mark a revolutionary change in Britain. Universities want the government to introduce a loan scheme for tuition fees and have suspended their own threatened action for now. They await Deari

But the government has doubts about more expansion. The Ti
34、mes newspaper agrees, complaining that quality has suffered as student numbers soared, with close tutorial supervision giving way to “mass production methods more typical of European universities.”31. The chief concern of British universities is .新东方在线 CET6 通关班网络课堂电子教材系列 阅读5A) how to tackle their p
35、resent financial difficultyB) how to improve their educational technologyC) how to expand the enrollment to meet the needs of enterprisesD) how to put an end to the current tendency of quality deterioration 32. We can learn from the passage that in Britain .A) higher education is provided free of ch

What was the percentage of high school graduates admitted to universities in Britain thirty years ago?A) About 15%. C) Below 10%.B) 20
37、% or so. D) Above 30%.34.

39、affect the quality of British higher education.C) British universities should help fight competition on world markets.D) European universities can better meet the needs of the modern world.Questions 36 to 40 are based on the following passage:Theres a simple premise behind what Larry Myers does for
40、a living: If you can smell it, you can find it.Myers is the founder of Auburn Universitys Institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devicesan artificial nose.For now, the subject of their research is little more than a stack of gleaming
41、chips tucked away in a laboratory drawer. But soon, such a tool could be hanging from the belts of police, arson(纵火 ) investigators and food-safety inspectors.The technology that they are working on would suggest quite reasonably that, within three to five years, well have some workable sensors read
42、y to use. Such devices might find wide use in places that attract terrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination.新东方在线 CET6 通关班网络课堂电子教材系列 阅读6The implications for revolutionary advances in public safety
43、 and the food industry are astonishing. But so, too, are the possibilities for abuse: Such machines could determine whether a woman is ovulating (排卵), without a physical examor even her knowledge.One of the traditional protectors of American liberty is that it has been impossible to search everyone.
44、 Thats getting not to be the case. Artificial biosensors created at Auburn work totally differently from anything ever seen before. Aromas can, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, c
45、hemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those current changes are logged into a computer that sorts out odors based on their electrical signatures.Myers says they expect to load a single fingernail-size chip with thousands of odor re
46、ceptors(感受器)， enough to create a sensor thats nearly as sensitive as a dogs nose.36. Which of the following is within the capacity of the artificial nose being developed?A) Monitoring food processing.B) Performing physical examinations.C) Locating places which attract terrorists.D) Detecting drugs a
47、nd water contamination. 37. A potential problem which might be caused by the use of an artificial nose is .A) a hazard to physical healthB) negligence of public safetyC) a threat to individual privacyD) an abuse of personal freedom 38. The word “logged”(Line 5, Para. 7) most probably means “ ”.A) pr
48、eset C) enteredB) simulated D) processed 39. To produce artificial noses for practical use, it is essential .A) to find chemicals that can alter the electrical current passing throughB) to develop microchips with thousands of odor receptorsC) to design a computer program to sort out smellsD) to invent chips sensitive to various chemicals40.
