17、, and D). You should deicide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Questions 21 to 25 are based on the following passage.Many Americans harbour a grossly distorted and exaggerated view of most of the risks surrounding food. Fer
18、gus Clydesdale, head of the department of food science and nutrition at the University of Massachusetts-Amherst, says bluntly that if the dangers from bacterially contaminated chicken were as great as some people believe, “the streets would be littered with people lying here and there.”Though the pu
19、blic increasingly demands no-risk food, there is no such thing. Bruce Ames, chairman of the biochemistry department at the University of California, Berkeley, points out that up to 10% of a plants weight is made up of natural pesticides (杀虫剂). Says he: “Since plants do not have jaws or teeth to prot
20、ect themselves, they employ chemical warfare.” And many naturally produced chemicals, though occurring in tiny amounts, prove in laboratory tests to be strong carcinogens-a substance which can cause cancer. Mushrooms (磨菇) might be banned if they were judged by the same standards that apply to food a
21、dditives (添加剂). Declares Christina Stark, a nutritionist at Cornell University: “Weve got fat worse natural chemicals in the food supply than anything man-made.”Yet the issues are not that simple. While Americans have no reason to be terrified to sit down at the dinner table, they have every reason
22、to demand significant improvements in food and water safety. They unconsciously and unwillingly take in too much of too many dangerous chemicals. If food already contains natural carcinogens, it does not make much sense to add dozens of new man-made ones. Though most people will withstand the small
23、amounts of contaminants generally found in food and water, at least a few individuals will probably get cancer one day be cause of what they eat and drink.To make good food and water supplies even better, the Government needs to tighten its regulatory standards, stiffen its inspection program and st
24、rengthen its enforcement policies. The food industry should modify some long-accepted practices or turn to less hazardous alternatives. Perhaps most important, consumers will have to do a better job of learning how to handle and cook food properly. The problems that need to be tackled exist all alon
25、g the food-supply chain, from fields to processing plants to kitchens.21.What does the author think of the Americans view of their food?A) They overstate the governments interference with the food industry.B) They are overoptimistic about the safety of their food.C) They overestimate the hazards of
26、their food.D) They overlook the risks of the food they eat.（C）22.The author considers it impossible to obtain no-risk food because _.A) no food is free from pollution in the environmentB) pesticides are widely used in agricultureC) many vegetables contain dangerous natural chemicalsD) almost all foo
27、ds have additives（C）23.By saying “they employ chemical warfare” (Line 4, Para. 2), Bruce Ames means “_”.A) plants produce certain chemicals to combat pests and diseasesB) plants absorb useful chemicals to promote their growthC) farmers use man-made chemicals to dissolve the natural chemicals in plan
28、tsD) farmers use chemicals to protect plants against pests and diseases（A）24.The reduction of the possible hazards in food ultimately depends on _.A) the governmentB) the consumerC) the processorD) the grower（B）25.What is the message the author wants to convey in the passage?A) Eating and drinking h
29、ave become more hazardous than before.B) Immediate measures must be taken to improve food production and processing.C) Health food is not a dream in modern society.D) There is reason for caution but no cause for alarm with regard to food consumption.（D）Questions 26 to 30 are based on the following p
30、assage.There are some each phenomena you can count on, but the magnetic field, someday is not of them. It fluctuates in strength, drifts from its axis, and every few 100,000 years undergo, dramatic polarity reversal-a period when North Pole becomes South Pole and South Pole becomes North Pole. But h
31、ow is the field generated, and why is it so unstable?Groundbreaking research by two French geophysicists promises to shed some light on the mystery. Using 80 metres of deep sea sediment (沉淀物) core, they have obtained measurements lots of magnetic-field intensity that span 11 polarity reversals and f
32、our million years. The analysis reveals that intensity appears to fluctuate with a clear, well-defined rhythm. Although the strength of the magnetic field varies irregularly during the short term, there seems to be an inevitable long-term decline preceding each polarity reversal. When the poles flip
33、a process that takes several hundred thousand years-the magnetic field rapidly regains its strength and the cycle is repeated.The results have caused a stir among geophysicists. The magnetic field is thought to originate from molten (熔化的) iron in the outer core, 3,000 kilometers beneath the earths s
34、urface. By studying mineral grains found in material ranging from rocks to clay articles, previous researchers have already been able to identify reversals dating back 170 million years, including the most recent switch 730,000 years ago. How and why they occur, however, has been widely debated. Sev
35、eral theories link polarity flips to external disasters such as meteor (陨星) impacts. But Peter Olson, a geophysicist at the Johns Hopkins University in Baltimore, says this is unlikely if the French researchers are right. In fact, Olson says intensity that predictably declines from one reversal to t
36、he next contradicts 90 percent of the models currently under study. If the results prove to be valid geophysicists will have a new theory to guide them in their quest to understand the earths inner physics. It certainly points the direction for future research.26.Which of the following titles is mos
37、t appropriate to the passage?A) Polarity Reversal: A Fantastic Phenomenon of Nature.B) Measurement of the Earths Magnetic-Field Intensity.C) Formation of the Two Poles of the Earth.D) A New Approach to the Study or Geophysics.（D）27.The word “flip” (Line 6, Para. 2) most probably means “_”.A) decline
38、B) intensifyC) fluctuateD) reverse（D）28.What have the two French geophysicists discovered in their research?A) Some regularity in the changes of the earths magnetic field.B) Some causes of the fluctuation of the earths magnetic field.C) The origin of the earths magnetic field.D) The frequency of pol
39、arity reversals.（A）29.The French geophysicists study is different from currently prevailing theories in _.A) its identification of the origin of the earths magnetic fieldB) the way the earths magnetic intensity is measuredC) its explanation of the shift in the earths polarityD) the way the earths fl
40、uctuation rhythm is defined（C）30.In Peter Oslos opinion the French experiment _.A) is likely to direct further research in the inner physics of the earthB) has successfully solved the mystery of polarity reversalsC) is certain to help predict external disastersD) has caused great confusion among the
41、 worlds geophysicists（A）Questions 31 to 35 are based on the following passage.Imagine a world in which there was suddenly no emotion-a world in which human beings could feel no love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to
42、 stay alive: knowing neither joy nor pleasure, anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotionless world would lack rewards and punishments. Society would soon disa
43、ppear: people would be as likely to harm one another as to provide help and support. Human relationships would not exist: in a world without friends or enemies, there could be no marriage, affection among companions, or bonds among members of groups. Societys economic underpinnings (支柱) would be des
44、troyed: since earning $10 million would be no more pleasant than earning $10, there would be no incentive to work. In fact, there would be no incentives of any kind. For as we will see, incentives imply a capacity to enjoy them.In such a world, the chances that the human species would survive are ne
45、xt to zero, because emotions are the basic instrument of our survival and adaptation. Emotions structure the world for us in important ways. As individuals, we categorize objects on the basis of our emotions. True we consider the length, shape, size, or texture, but an objects physical aspects are l
46、ess important than what it has done or can do to ushurt us, surprise us, anger us or make us joyful. We al so use categorizations colored by emotions in our families, communities, and overall society. Out of our emotional experiences with objects and events comes a social feeling of agreement that c
47、ertain things and actions are good and others are bad, and we apply these categories to every aspect of our social lifefrom what foods we eat and what clothes we wear to how we keep promises and which people our group will accept. In fact, society exploits our emotional reactions and attitudes, such
48、 as loyalty morality, pride shame, guilt, fear and greed, in order to maintain itself It gives high rewards to individuals who perform important tasks such as surgery, makes heroes out of individuals for unusual or dangerous achievements such as flying fighter planes in a war, and uses the legal penal (刑法的) system to make people afraid to engage in antisocial acts.31.The reason why people might not be able to stay alive in a world without emot
