8、ogrammedC.work more quicklyD.understand their instructionsThe “balance of nature“ is not an empty phrase. Nature provides a population to occupy a suitable environment and cuts down surplus population to fit the available food supply. One means of reducing surplus population is predators (食肉动物); oth

9、ers are parasites (寄生虫) and diseases. Also, population density produces nervous disorders and even drives animals to mass migrations, like the lemmings (旅鼠) of Norway who plunge into(跳人) the sea. That predators populations increase to control other animals has long been known. Many years ago, the Hu

10、dsons Bay Company records revealed that the fox population went up and down about a year after the rabbit population had gone up and down. Sometimes a situation occurs in which the predators population is reduced to a level below that which nature can readily replace. On Valcour Island in Lake Champ

11、lain (New York) , a costly campaign resulted in the elimination of predatory animals only to have birds and small animalsincluding grouse (松鸡) and hares, popular game(猎物)increase for four years afterward. Then lacking predator control, nature resorted to diseases to cut down these populations. Jamai

12、ca had an example of natures persistence in providing animals for existing habits. Sugar planters, about 75 years ago, imported mongooses to control rats. The mongooses killed off the rats and, with plentiful food, multiplied. Rats became scarce and the mongooses ate lambs, kids, puppies(小狗) , and w

13、ildlife. Eventually, food became scarce and the mongooses population declined.（分数：10.00）(1).According to the article, the phrase “balance of nature“ means_.（分数：2.00）A.the relation of wildlife to manB.the adequacy of the food supply to support its animal populationC.the ratio of small game to predato

14、rsD.the destruction of predators(2).The effect of predator control over other animal populations_.（分数：2.00）A.has just been learnedB.is not recent knowledgeC.is not important nowD.was learned in Norway(3).When predators control is not available, nature brings animal population into balance by resorti

16、ngooses to control ratsB.Man should never tamper(损害) with natureC.To upset the balance of nature can be troublesomeD.Man has complete control over natureIn spite of the strong opposition to new and strict environmental laws, however, it is still possible to attack the problem of chemical pollution;

17、but we must attack it from three directions. First, we need more independent research into the effects of chemicals by scientists who are not paid by the government or by large industrial companies. Second, scientists need to educate the general public and inform them about the dangers of chemicals

18、in the environment. If the public knows that a certain chemical threatens the health of their children, then it will put pressure on politicians, in local and national government. If the politician want to remain in office, they will take action to correct the long-term economic costs of chemicals.

19、It will be extremely expensive to clean areas of land which are contaminated (污染) by chemicals; it will be even more costly to give medical treatment to people who are suffering from serious illnesses after exposure to dangerous chemicals. If governments realize this, the short-term economic benefit

20、s of chemicals will seem much less attractive to them. If we can put pressure on governments in these three ways, perhaps they will begin to behave more responsibly. They will perhaps pass new laws against pollution and enforce them strictly. Perhaps, then, the chemical producers will begin to behav

21、e more responsibly.（分数：10.00）(1).Which of the following might be the best title for the passage?（分数：2.00）A.The Environment in DangerB.The Problem of Chemical PollutionC.New and Strict Environmental LawsD.Possible Solutions to Chemical Pollution(2).Which of the following statements best describes the

22、 organization of the passage?（分数：2.00）A.Two contrasting views of a problem are presented.B.A procedure is explained and its importance is emphasized.C.A general statement is given and possible ways are presented.D.Recent scientific advancements are outlined in order of importance.(3).Which of the fo

23、llowing is true of the governments mentioned in the passage?（分数：2.00）A.They are already behaving in an extremely responsible way.B.They do not believe that it is possible to solve the chemical pollution.C.They think chemicals do little harm to the health of humans.D.They are unwilling to stop the us

24、e of certain chemicals.(4).Which of the following can be inferred from the passage?（分数：2.00）A.The economy is more important to governments than the peoples health is.B.Governments think chemicals bring them more economic pollution.C.The public knows enough about the dangers of chemical pollution.D.T

25、he governments fully realize the long-term economic costs of chemical pollution.(5).According to the passage, what will happen if the governments stop the use of some chemicals?（分数：2.00）A.The economy of the countries will suffer.B.Unemployment in the countries will grow.C.Some people and scientists

26、will criticize them.D.The chemical producers will strongly protest.Believe it or not, optical illusion can cut highway crashes. Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons, painted on th

27、e roads make drivers think that they are driving faster than they really are, and thus drivers slow down. Now the American Automobile Association Foundation for Traffic Safety in Washington D. C. is planning to repeat Japans success. Starting next year, the foundation will paint chevrons and other p

28、atterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes. Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests

29、in areas where speed-related hazards are the greatestcurves, exit slopes, traffic circles, and bridges.Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as driver

30、s become used to seeing the painted bars. Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.（分数：10.

31、00）(1).The passage mainly discusses_.（分数：2.00）A.a new way of highway speed controlB.a new pattern for painting highwaysC.a new approach to training driversD.a new type of optical illusion(2).On roads painted with chevrons, drivers tend to feel that_.（分数：2.00）A.they should avoid speed-related hazards

32、B.they are driving in the wrong laneC.they should slow down their speedD.they are approaching the speed limit(3).The advantage of chevrons over straight, horizontal bars is that the former_.（分数：2.00）A.can keep drivers awakeB.can cut road accidents in halfC.will have a longer effect on driversD.will

33、look more attractive(4).The American Automobile Association Foundation for Traffic Safety plans to_.（分数：2.00）A.try out the Japanese method in certain areasB.change the road signs across the countryC.replace straight, horizontal bars with chevronsD.repeat the Japanese road patterns(5).What does the a

34、uthor say about straight, horizontal bars painted across roads?（分数：2.00）A.They are falling out of use in the United States.B.They tend to be ignored by drivers in a short period of time.C.They are applicable only on broad roads.D.They cannot be applied successfully to traffic circles.A breakthrough

35、突破) in the provision of energy from the sun for the European Economic Community (EEC) could be brought forward by up to two decades, if a modest increase could be provided in the EEC s research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EE

36、C s scientific laboratories at Ispra, near Milan. The senior West German scientist in charge of the Communitys solar energy program, Mr. Joachim Gretz, told journalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three percent of the Co

37、mmunitys energy requirements even after the year 2000. But he said that with a modest increase in the present sums, devoted by the EEC to this work it was possible that the breakthrough could be achieved by the end of the next decade. Mr. Gretz calculates that if solar energy only provided three per

38、cent of the EECs needs, this could still produce a saving of about a billion pounds in the present bill for imported energy each year. And he believes that with the possibility of utilizing more advanced technology in this field it might be possible to satisfy a much bigger share of the Community s

39、future energy needs. At present the EEC spends about 2. 6 millions a year on solar research at Ispra, one of the EECs official joint research centers, and another 3 millions a year in indirect research with universities and other independent bodies.（分数：10.00）(1).The phrase “be brought forward“ in Li

40、ne 2 most probably means_.（分数：2.00）A.be expectedB.be completedC.be advancedD.be introduced(2).Some scientists believe that a breakthrough in the use of solar energy depends on_.（分数：2.00）A.sufficient fundingB.further experimentsC.advanced technologyD.well-equipped laboratories(3).According to Mr. Gre

41、tz, the present sum of money will enable the scientists to provide_.（分数：2.00）A.a little more than 3% of the EECs needs after the year 2000B.3% of the EECs needs before the year 2000C.less than 3% of the EECs needs before the year 2000D.only 3% of the EECs needs even after the year 2000(4).Which of t

42、he following is NOT true according to the passage?（分数：2.00）A.The EEC spends one billion pounds on imported energy each year.B.At the present level of research spending, it is difficult to make any significant progress in the provision of energy from the sun.C.The desired breakthrough could be obtain

43、ed by the end of the next decade if investment were increased.D.The total yearly spending of the EEC on solar energy research amounted to almost 6 million dollars.(5).The application of advanced technology to research in solar energy_.（分数：2.00）A.would lead to a big increase in research fundingB.woul

44、d make it unnecessary to import oilC.would make it possible to meet the future energy needs of the EECD.would provide a much greater proportion of the Communitys future energy needs专升本英语（阅读）模拟试卷 110 答案解析(总分：50.00，做题时间：90 分钟)一、BPart III Rea(总题数：5，分数：50.00)A computer is a machine designed to perform w
