1、考研英语-357 及答案解析(总分：100.00，做题时间：90 分钟)一、Section Use of Eng(总题数：1，分数：10.00)Most plants can make their own food from sunlight, (1) some have discovered that stealing is an easier way to live. Thousands of plant species get by (2) photosynthesizing, and over 400 of these species seem to live by pilfering

2、 sugars from an underground (3) of fungi(真菌). But in (4) a handful of these plants has this modus operandi been traced to a relatively obscure fungus. To find out how (5) are (6) , mycologist Martin Bidartondo of the University of California at Berkeley and his team looked in their roots. What they

3、found were (7) of a common type of fungus, so (8) that it is found in nearly 70 percent of all plants. The presence of this common fungus in these plants not only (9) at how they survive, says Bidartondo, but also suggests that many ordinary plants might prosper from a little looting, too.Plants hav

4、e (10) relations to get what they need to survive. Normal, (11) plants can make their own carbohydrates through photosynthesis, but they still need minerals. Most plants have (12) a symbiotic relationship with a (13) network of what are called mycorrhizal fungi, which lies beneath the forest (14) .

5、The fungi help green plants absorb minerals through their roots, and (15) , the plants normally (16) the fungi with sugars, or carbon. With a number of plants sharing the same fungal web, it was perhaps (17) that a few cheaters-dubbed epiparasites-would evolve to beat the system. (18) , these plants

6、 reversed the flow of carbon, (19) it into their roots from the fungi (20) releasing it as “payment. /（分数：10.00）A.butB.ifC.becauseD.thoughA.forB.withC.toD.withoutA.realmB.netC.relationD.webA.onlyB.almostC.virtuallyD.actuallyA.othersB.the othersC.otherD.the otherA.getting byB.getting onC.getting thro

9、ext 1(总题数：1，分数：10.00)A factory that makes uranium fuel for nuclear reactors had a spill so bad it kept the plant closed for seven months last year and became one of only three events in all of 2006 serious enough for the Nuclear Regulatory Commission to include in an annual report to Congress. After

10、 an investigation, the commission changed the terms of the factorys license and said the public had 20 days to request a hearing on the changes.But no member of the public ever did. In fact, no member of the public could find out about the changes. The document describing them, including the notice

11、of hearing rights for anyone who felt adversely affected, was stamped “official use only,“ meaning that it was not publicly accessible.The agency would not even have told Congress which factory was involved were it not for the efforts of Gregory B. Jaczko, one of the five commissioners. Mr. Jaczko i

12、dentified the company, Nuclear Fuel Services of Erwin, Tenn. , in a memorandum that became part of the public record. His memorandum said other public documents would allow an informed person to deduce that the factory belonged to Nuclear Fuel Services.Such secrecy by the Nuclear Regulatory Commissi

13、on is now coming under attack by influential members of Congress. These lawmakers argue that the agency is withholding numerous documents about nuclear facilities in the name of national security, but that many withheld documents are not sensitive. The lawmakers say the agency must rebalance its pen

14、chant for secrecy with the publics right to participate in the licensing process and its right to know about potential hazards. The agency, the congressmen said, “ has removed hundreds of innocuous documents relating to the N. F. S. plant from public view. “With a resurgence of nuclear plant constru

15、ction expected after a 30-year hiatus, agency officials say frequently that they are trying to strike a balance between winning public confidence by regulating openly and protecting sensitive information. A commission spokesman, Scott Burnell, said the “official use only“ designation was under revie

16、w.As laid out by the commissions report to Congress and other sources, the event at the Nuclear Fuel Service factory was discovered when a supervisor saw a yellow liquid dribbling under a door and into a hallway. Workers had previously described a yellow liquid in a “glove box,“ a sealed container w

17、ith gloves built into the sides to allow a technician to manipulate objects inside, but managers had decided it was ordinary uranium. In fact, it was highly enriched uranium that had been declared surplus from the weapons inventory of the Energy Department and sent to the plant to be diluted to a st

18、rength appropriate for a civilian reactor. If the material had gone critical, “it is likely that at least one worker would have received an exposure high enough to cause acute health effects or death,“ the commission said.Generally, the Nuclear Regulatory Commission does describe nuclear incidents a

19、nd changes in licenses. But in 2004, according to the committees letter, the Office of Naval Reactors, part of the Energy Department, reached an agreement with the commission that any correspondence with Nuclear Fuel Services would be marked “official use only. /（分数：10.00）(1).Why did no member of th

20、e public request any hearing?（分数：2.00）A.Because the general public often show no interest in such matters.B.Because the hearing rights of the public are adversely affected.C.Because the public has stamped the documents “official use only“.D.Because the public are not aware of the changes in the firs

21、t place.(2).It can be inferred from the first three paragraphs that（分数：2.00）A.the public have access to Mr. Jaczkos memorandum.B.the agency never told Congress which factory was involved.C.the Nuclear Fuel Services is a non-profitable government company.D.documents marked “Official Use Only“ are acc

22、essible to the informed.(3).NRC is criticized by Congress members chiefly because（分数：2.00）A.law makers draw the conclusion that NRC has illegal documents.B.they think NRC is hiding more information than it should be.C.the public have the rights to know any potential hazards.D.they think nuclear faci

23、lities are not a matter of national security.(4).The word “innocuous“ ( paragraph 4) is closest in meaning to（分数：2.00）A.insensitive.B.confidential.C.innocent.D.harmful(5).Which of the following is true according to the text?（分数：2.00）A.The 2006 incidence occurred because of the carelessness of a supe

24、rvisor.B.Yellow liquids in a glove box should always be handled with heed.C.Highly enriched uranium can be diluted for civilian uses.D.At least one worker has been seriously affected in the 2006 incidence.五、Text 2(总题数：1，分数：10.00)The history of modern pollution problems shows that most have resulted

25、from negligence and ignorance. We have an appalling tendency to interfere with nature before all of the possible consequences of our actions have been studied in depth. We produce and distribute radioactive substances, synthetic chemicals and many other potent compounds before fully comprehending th

26、eir effects on living organisms. Our education is dangerously incomplete.It will be argued that the purpose of science is to move into unknown territory, to explore, and to discover. It can be said that similar risks have been taken before, and that these risks are necessary to technological progres

27、s.These arguments overlook an important element. In the past, risks taken in the name of scientific progress were restricted to a small place and brief period of time. The effects of the processes we now strive to master are neither localized nor brief. Air pollution covers vast urban areas. Ocean p

28、ollutants have been discovered in nearly every part of the world. Synthetic chemicals spread over huge stretches of forest and farmland may remain in the soil for decades and years to come. Radioactive pollutants will be found in the biosphere for generations. The size and persistence of these probl

29、ems have grown with the expanding power of modern science.One might also argue that the hazards of modern pollutants are small compared with the dangers associated with other human activity. No estimate of the actual harm done by smog, fallout, or chemical residues can obscure the reality that the r

30、isks are being taken before being fully understood.The importance of these issues lies in the failure of science to predict and control human intervention into natural processes. The true measure of the danger is represented by the hazards we will encounter if we enter the new age of technology with

31、out first evaluating our responsibility to environment.（分数：10.00）(1).Which of the following adjectives may best describe the tone of this text?（分数：2.00）A.Unconcerned.B.Humorous.C.Serious.D.Exaggerated.(2).The text is mainly about（分数：2.00）A.the nature of scientific progress.B.the relationship between

32、 the progress of science and pollution.C.certain factors that harm the circumstance.D.the awareness of our responsibility to environment.(3).The author would most probably agree that the origin of environmental pollution lies in（分数：2.00）A.the indifference to the condition of the environment.B.the la

33、ck of the ability to control the progress of science.C.the inability of science to deal with certain human endeavors.D.the ignorance of the disposal of pollutants.(4).As used in the second sentence of the first paragraph, the phrase “in depth“ means（分数：2.00）A.fully and thoroughly.B.distantly and rem

34、otely.C.seriously and extent.D.strongly and unpleasantly.(5).What the people really ignore in the debate is that（分数：2.00）A.the effects of the modern pollutants on the living organisms.B.the present situation is remarkedly different from the past.C.the stress of progress of science to the neglect of

35、environmental protection.D.the serious consequence followed by the development of science.六、Text 3(总题数：1，分数：10.00)Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forwar

36、d are often never mentioned at all. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured a field; but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars in th

37、e great cities of the world you will find the figure of a conqueror or a general or a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but

38、they are not the most civilized. Animals fight; so do savages; hence to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized. Even being good at getting other people to fight for you and telling them how to do it most efficiently-this, af

39、ter all, is what conquerors and generals have done-is not being civilized. People fight to settle quarrels. Fighting means killing, and civilized peoples ought to be able to find some way of settling their disputes other than by seeing which side can kill off the greater number of the other side, an

40、d then saying that that side which has killed most has won. And not only has won, but, because it has won, has been in the right. For that is what going to war means; it means saying that might is right.That is what the story of mankind has on the whole been like. Even our own age has fought the two

41、 greatest wars in history, in which millions of people were killed or mutilated. And while today it is true that people do not fight and kill each other in the streets-while, that is to say, we have got to the stage of keeping the rules and behaving properly to each other in daily life-nations and c

42、ountries have not learnt to do this yet, and still behave like savages.But we must not expect too much. After all, the race of men has only just started. From the point of view of evolution, human beings are very young children indeed, babies, in fact, of a few months old. Scientists reckon that the

43、re has been life of some sort on the earth in the form of jellyfish and that kind of creature for about twelve hundred million years; but there have been men for only one million years, and there have been civilized men for about eight thousand years at the outside. These figures are difficult to gr

44、asp; so let us scale them down. Suppose that we reckon the whole past of living creatures on the earth as one hundred years; then the whole past of man works out at about one month, and during that month there have been civilizations for between seven and eight hours. So you see there has been littl

45、e time to learn in, but there will be oceans of time in which to learn better. Taking mans civilized past at about seven or eight hours, we may estimate his future, that is to say, the whole period between now and when the sun grows too cold to maintain life any longer on the earth, at about one hun

46、dred thousand years. Thus mankind is only at the beginning of its civilized life, and as I say, we must not expect too much. The past of man has been on the whole a pretty beastly business, a business of fighting and bullying and gorging and grabbing and hurting. We must not expect even civilized pe

47、oples not to have done these things. All we can ask is that they will sometimes have done something else.（分数：10.00）(1).The first sentence of the opening paragraph indicates that（分数：2.00）A.most history books were written by conquerors, generals and soldiers.B.no one who really helped civilisation for

48、ward is mentioned in any history book.C.history books neglect the real heroes behind civilisation.D.conquerors, generals and soldiers should not be mentioned in history books.(2).On all the highest pillars in the great cities of the world, we find（分数：2.00）A.the figure of the same conqueror or genera

49、l or soldier.B.the figure of some conqueror or general or soldier.C.a figure reprsenting the number of conquerors, generals or soldiers in that country.D.the figure of a person who helped civilization forward.(3).In the authors opinion, the countries that ruled over a large number of other countries are（分数：2.00）A.certainly not the greatest in any way.B.neither the greatest nor the most civilized.C.possibly the most civilized but not the greatest.D.possibly the greatest in some sense but not the most civilized.(4).By saying“ From the point of view of evolution, human beings are
