19、总题数：0，分数：0.00)八、Passage 1(总题数：1，分数：5.00)Mans puzzlement and preoccupation with time both derive ultimately from his unique relationship to it. All animals exist in time and are changed by it; only man can control it.Like Proust, the French author whose experiences became his literary capital, man ca

20、n recapture the past. He can also summon up things to come, displaying imagination and foresight alone with memory. It really can be argued, that memory and foresightedness are the essence of intelligence: that mans ability to manipulate time, to employ both past and future as guides to present acti

21、on, is what makes him human.To be sure, many animals can react to time after a fashion A rat can learn to press a lever that will, after a delay of some 25 seconds, reward it with a bit of food. But if the delay stretches beyond 30 seconds, the animal is stumped. It can no longer associate the rewar

22、d so “far“ in the future with the present lever-pressing.Monkeys, more smart than rats, are better able to deal with time. If one of them is allowed to see food being hidden under one of two cups, it can pick out the right cup even after 90 seconds have passed. But after that time interval, the monk

23、eys hunt for the food is no Better than chance predicts.With the apes, mans nearest cousins, “time sense“ takes a big step forward. Even under laboratory conditions, quite different from those they encounter in the wild, apes somemnes show remarkable ability to manipulate the present to obtain a fut

24、ure goal. A chimpanzee, for example, can learn to stack two boxes, one on the other, as a platform from which it can reach a hanging banana. Chimpanzees, indeed, carry their ability to deal with the future to the threshold of human capacity: they can make tools. And it is by the making of tools phys

25、ical tools as crude as a stone chopper, mental tools as subtle as a mathematical equationthat man characteristically prepares for future contingencies.Chimpanzees in the wild have been seen to strip a twig of its leaves to make a probe for extracting termites from their hole. Significantly, however,

26、 the ape does not make his tool before setting out on a termite hunt, but only when it actually sees the insects or their nest. Here, as with the banana and the crates, the ape can cope only with a future that is immediate and visible and thus halfway into the present（分数：5.00）(1).According to the ar

27、ticle, which of the following statements ts TRUE?（分数：1.00）A.Chimpanzees sense of time is as good as mans.B.Man developed from apes.C.Memory and foresight contribute to intelligence.D.Monkeys and apes are almost as intelligent as man(2).From the sentence “Like Proust. the French author whose experien

28、ces became his literary capital, man can recapture the past, you can tell that Proust _.（分数：1.00）A.wrote primarily to improve his future lifeB.discovered things about his future lifeC.described mans development of time senseD.wrote about his past experiences(3).It is significant that chimpanzees mak

29、e tools, but it is more important that _.（分数：1.00）A.they never make tools before they need themB.they can make up simple equationsC.they stack items to make platformsD.the tools are crude(4).The word “contingencies“ in the fifth paragraph means _.（分数：1.00）A.the making of toolsB.dependent conditionsC

30、.incidental thoughtsD.events that may occur(5).This article is about _.（分数：1.00）A.time sense in animalsB.how mans time sense separates him from animalsC.mans preoccupation with past and future eventsD.how apes understand time relationships九、Passage 2(总题数：1，分数：5.00)There are a great many careers in w

31、hich the increasing emphasis is on specialization. You find these careers in engineering, in production, in statistical work, and in teaching. But there is an increasing demand for people who are able to take in a great area at a glance, people who perhaps do not know too much about any one field. T

32、here is, in other words, a demand for people who are capable of seeing the forest rather than the trees, of making general judgments. We can call these people “generalists“. And they are particularly needed for positions in administration, where it is their job to see that other people do their work

33、, where they have to plan for other people, to organize other peoples work, to begin it and judge it.The specialist understands one field; his concern is with technique and tools. He is a “trained“ main and his educational background is properly technical or professional. The generalists and especia

34、lly the administrators deal with people; his concern is with leadership, with planning, and with direction giving. He is an “educated“ man; and the humanities are his strongest foundation. Very rarely is a specialist capable of being an administrator. And very rarely is a good generalist also a good

35、 specialist in a particular field. Any organization needs both kinds of people, though different organizations need them in different proportions. It is your task to find out, during your training period, into which of the two kinds of jobs you fit, and to plan your ca-leer accordingly.Your first jo

36、b may turn out to be the right job for you but this is pure accident. Certainly you should not change jobs constantly or people will become suspicious of your ability to hold any job. At the same time, you must not look upon the first job as the final job. It is primarily a training job, a chance to

37、 understand yourself and your fitness for being an employee.（分数：5.00）(1).There is an increasing demand for _.（分数：1.00）A.all round people in their own fieldsB.generalists who are capable of making general judgmentC.people whose educational background is either technical or professionalD.specialists w

38、hose chief concern is to provide administrative guidance to others(2).The specialist is _.（分数：1.00）A.a man whose job is to train other peopleB.a man who has been trained in more than one fieldC.a man who can see the forest rather than the treesD.a man whose concern is mainly with technique and tools

39、(3).The administrator is _.（分数：1.00）A.a “trained“ man who is more a specialist than a generalistB.a man who sees the trees as well as the forestC.a man who is very strong in the humanitiesD.a man who is an “educated“ specialist(4).During your training period, it is important _.（分数：1.00）A.to try to b

40、e a generalistB.to choose a profitable jobC.to find an organization which fits youD.to decide whether you are fit to be a specialist or a generalist(5).A mans first job _.（分数：1.00）A.is never the right job for himB.should not be regarded as his final jobC.should not be changed or people will become s

41、uspicious of his ability to hold any jobD.is primarily an opportunity to fit himself for his final job十、Passage 3(总题数：1，分数：5.00)On Tuesday August 11th, 1911, a young artist, Louis Beraud, arrived at the Louvre in Paris to complete a painting of the Salon Carre. This was the room where the worlds mos

42、t famous painting, the Mona Lisa by Leonardo da Vinci, was on display. To his surprise there was an empty space where the painting should have been. At 11 oclock the museurn authorities realized that the painting had been stolen. The next day headlines all over the world announced the theft.Actually

43、 the Leonardo had been gone for more than twenty-four hours before anyone noticed it was missing. The museum was always closed on Mondays for maintenance. Just before closing time on Sunday three men had entered the museum, where they had hidden themselves in a storeroom. The actual theft was quick

44、and simple. Early the next morning Perrugia removed the painting from the wall while the others kept watch. Then they went out a hack exit.Nothing was seen or heard of the painting for two years when Perrugia tried to sell it to a dealer for half a million lire. Perrugia was arrested on December 13t

45、h Perrugia claimed he had stolen it as an act of patriot-ism, because, he said, the painting had been looted from the Italian nation by Napoleon. Perrugia was imprisoned for 7 months. It seemed that the crime of the century had been solved.But had it? Perrugia was keen to claim all responsibility fo

46、r the theft, and it was twenty years before the whole story came out. In fact Perrugia bad been working for two master criminals, Valfierno and Chaudron, who went unpunished for their crime. They would offer to steal a famous painting from a gallery for a crooked dealer or an unscrupulous private co

47、llector. They would then make a copy of the picture and, with the help of bribed gallery attendants, tape the copy to the back of the original painting. The dealer would then be taken to the gallery and would be invited to make a secret mark on the back of the painting. Of course the dealer would ac

48、tually be marking the copy. Valfierno would later produce forged newspaper cuttings announcing the theft of the original, and then produce the copy, complete with secret marking. If the dealer were to see the painting still in the gallery, he would be persuaded that it was a copy, and that he posses

49、sed the genuine one.Chaudron then painted not one, but six copies of the Mona Lisa, using 400-year-old wood panels from antique Italian furniture The forgeries were carefully aged, so that the varnish was cracked and dirty. Valfierno commissioned Perrugia to steal the original, and told him to hide it until Valfierno contacted him Perrugia waited in vain in a tiny room in Paris with the painting, but
