单选题"Where is the university?" is a question many visitors to Cambridge ask, but no one can give them a clear answer for there is no wall to be found around the university. The university is the city. You can find classroom buildings, libraries, museums and offices of the university all over the city. And most of its members are the students and teachers or professors of the thirty-one colleges. Cambridge was already a developing town long before the first students and teachers arrived about 800 years ago. It grew up by the river Granta, as the Cam was once called. A bridge was built over the river as early as 875. In the fourteenth and fifteenth centuries more and more land was used for college buildings. The town grew much faster in the nineteenth century after the opening of the railway in 1845. Cambridge became a city in 1951 and now it has a population (人口) of over 100,000. Many young students want to study at Cambridge. Thousands of people from all over the world come to visit the university town. It has become a famous place all around the world.

单选题Placing a human being behind the wheel of an automobile often has the same curios effect as cutting certain fibres in the brain. The result in either case is more primitive behaviour. Hostile feelings are apt to be expressed in an aggressive way. The same man who will step aside for a stranger at a doorway will, when behind the wheel, risk an accident trying to beat another motorist through an intersection. The importance of emotional factors in automobile accidents is gaining recognition. Doctors and other scientists have concluded that the highway death toll resembles a disease epidemic and should be investigated as such. Dr. Ross A. McFarland, an associate professor of industrial Hygiene at the Harvard University School of Public Health, aid that accidents "now constitute a greater threat to the safety of large segments of the population than diseases do. " Accidents are the leading cause of death between the ages of 1 and 35. About one third of all accidental deaths and one seventh of all accidental injuries are caused by motor vehicles. Based on the present rate of vehicle registration, unless the accident rate is cut in half, one of every 10 persons in the country will be killed or injured in a traffic accident in the next 15 years. Research to find the underlying causes of accidents and to develop ways to detect drivers who are apt to cause them is being conducted at universities and medical centres. Here are some of their findings so far. A man drives as he lives. If he is often in trouble with collection agencies, the courts, and police, chances are he will have repeated automobile accidents. Accident repeaters usually are egocentric, exhibitionistic, resentful of authority, impulsive, and lacking in social responsibility. As a group, they can be classified as borderline psychopathic personalities, according to Dr. McFarland. The suspicion, however, that accident repeaters could be detected in advance by screening out persons with more hostile impulses is false. A study at the University of Colorado showed that there were just as many overly hostile persons among those who had no accidents as among those with repeated accidents. Psychologists currently are studying Denver high school pupils to test the validity of this concept. They are making psychological evaluations of the pupils to see whether subsequent driving records will bear out their thesis.

单选题{{B}}Part A{{/B}} Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. {{B}}Text 1{{/B}} Office jobs are among the positions hardest hit by computation. Word processors and typists will lose about 93,000 jobs over the next few years, while 57,000 secretarial jobs will vanish. Blame the PC: Today, many executives type their own memos and carry their "secretaries" in the palms of their hands. Time is also hard for stock clerks, whose ranks are expected to decrease by 68,000. And employees in manufacturing firms and wholesalers are being replaced with computerized systems. But not everyone who loses a job will end up in the unemployment line. Many will shift to growing positions within their own companies. When new technologies shook up the telecomm business, telephone operator Judy Dougherty pursued retraining. She is now a communications technician, earning about $ 64,000 per year. Of course, if you've been a tollbooth collector for the past 30 years, and you find yourself replaced by an E-ZPass machine, it may be of little consolation to know that the telecomm field is booming. And that's just it: The service economy is fading; welcome to the expertise (专门知识 ) economy. To succeed in the new job market, you must be able to handle complex problems. Indeed, all but one of the 50 highest-paying occupations--air-traffic controller—demand at least a bachelor's degree. For those with just a high school diploma, it's going to get tougher to find a well-paying job. Since fewer factory and clerical jobs will be available, what's left will be the jobs that computation can't kill: Computers can't clean offices, or care for Alzheimer's patients. But, since most people have the skills to fill those positions, the wages stay painfully low, meaning computation could drive an even deeper wedge between the rich and poor. The best advice now: Never stop learning, and keep up with new technology. For busy adults, of course, that can be tough. The good news is that the very technology that's reducing so many jobs is also making it easier to go back to school—without having to sit in a classroom. So-called Internet distance learning is hot, with more than three million students currently enrolled, and it's gaining credibility with employers. Are you at risk of losing your job to a computer?

单选题We can learn from the passage that in Britain ______.

单选题What does the word "undermine" in Paragraph 4 mean?

单选题Use of the illegal drag named Ecstasy (MDMA) has increased alarmingly in Britain over the last few years, and in 1992 the British Medical Journal claimed that at least seven deaths and many severe adverse reactions have followed its use as a dance drug.14 deaths have so far been attributed to the drug in Britain although it is possible that other drugs contributed to some of those deaths. While it is true that all drugs by their very, nature change the way in which the body reacts to its environment and are therefore potentially dangerous, it is still unclear whether casual use of Ecstasy is as dangerous as authorities believe. What is certain is that the drug causes distinct changes to the body which, unless understood, may lead to fatal complications in certain circumstances. In almost all cases of MDMA related deaths in Britain, overheating of the body and inadequate replacement of fluids have been noted as the primary causes of death. Yet in the US, studies appear to implicate other causes. It seems that normal healthy people are unlikely to die as a result of taking MDMA, but people with pre-existing conditions such as a weak heart or asthma may react in extreme ways and are well advised not to take it. Not all physical problems associated with the drug are immediate. Medium term and long term effects have been reported which are quite disturbing, yet not all are conclusively linked to the drug's use. Medium term effects include the possibility of contracting the liver disease hepatitis or risking damage to the kidneys. However, animal studies show no such damage, although it is readily admitted by researchers that animal studies are far from conclusive since humans react in different ways than rats and monkeys to the drug. Perhaps the most damning evidence urging against the use of Ecstasy is that it is undoubtedly an addictive substance, but one that quickly loses its ability to transport the mind, while it increases its effect upon the body. Yet, unlike the classic addictive drugs, Ecstasy does not produce physical withdrawal symptoms. In fact, because one becomes quickly tolerant of its effect on the mind, it is necessary to forgo its use for a while in order to experience again its full effect. Any substance which produces such a strong effect on the user should be treated with appropriate respect and caution.

单选题Human intelligence and the IQ scales used to measure it once again are becoming the focus of fiery debate As argument rages over declining test scores in the nation's schools, an old but explosive issue is reappearing: What is intelligence—and is it determined largely by genetics? The controversy erupted more than a decade ago when some US scholars saw a racial pattern in the differing scores of students taking intelligence and college-entrance tests. Now, the racial issue is being joined by others. Teachers, psychologists, scientists and lawyers argue over the question of whether IQ —intelligence quotient — tests actually measure mental ability, or if findings are skewed by such factors as family background, poverty and emotional disorders. Moreover, some authorities assert that the rise in the number of college-educated Americans and their tendency to marry among themselves are creating a class of super-smart children of brainy parents — and, on the other side of the scale, a lumpenproletariat of children reflecting the supposedly inferior brainpower of their parents. Critics such as Harvard University biologist Richard C. Lewontin disagree. If mental ability were largely determined by inheritance, he says, efforts to enhance intelligence through the betterment of both home and child-rearing environments could only be marginally effective. He comments: "Genetic determinism could be used to justify existing social injustice as predetermined and inevitable and would render efforts made toward equalitarian goals as useless. " Supporting Lewontin in this is J. McVicker Hunt, a professor at the University of Illinois, who maintains that IQ levels can be raised significantly by exposing children at an early age to stimulating environments. Hunt's studies show that early help in such areas as education and nutrition can raise a child's IQ by an average of 30 to 35 points. At stake in the uproar over IQ is the national commitment to improve the capabilities of the poor by investing billions of dollars annually in educational, medical and job programs.

单选题{{B}}Passage 3{{/B}} On 5th December, 1945; five bombers from a United States Naval Air Station left Fort Lauderdale, Florida, on a routine training flight over the Atlantic Ocean, east of Florida. A short time later the base received radio messages from the bombers (Flight 19) ,saying that they were lost. Then radio contact was broken The flight did not return, and the planes that were sent to look for the bombers also failed to return. A massive search operation was mounted, but no trace of the missing planes or their pilots was found. They had simply and inexplicably disappeared. This event was sufficient to confirm in many people's minds that the so-called "Devil's Triangle". or "Bermuda Triangle" —a section of the North Atlantic bounded roughly by Bermuda, Florida and Puerto Rico— really was haunted. and in some mysterious way was responsible for the loss of ships and planes. In all, in this area (3 900 000 square kilometres) of open sea, more than 50 ships and 90 planes have mysteriously disappeared. These include the US Navy ship Cyclops in 1918 and the merchant vessel Marine Sulphur Queen in 1963. In the same year two US Air Force KC 135 planes also disappeared without trace. In other words, it is not only small boats and planes that have vanished in the are4,but the most modem and best-equipped too. Perhaps the most dramatic shipping loss in the area was the US Navy nuclear submarine Scorpion. This vessel, like others before her, disappeared without explanation in May, 1968. Some months later she was found on the bottom of the ocean, but the reason for her loss has not been properly explained. Many theories about the area have been proposed, and whole books have been written on the subject. It has been suggested, for example, that the disappearances are caused by unknown magnetic forces from outer space or from the bottom of the sea. There is also a theory about underwater volcanic action that affects shipping, and another that suggests the lost continent of Atlantis, which according to legend lies somewhere beneath the Atlantic, is involve& However, others state that it is more likely that there is nothing special about this imaginary triangle of water, and that it is a product of sensational journalism. After all, ships, boats and planes are lost at sea in all parts of the world due to weather, mechanical failure or human error, and several of the losses are mysterious. The Marie Celeste, an American cargo boat, for example, was found in 1872 off the coast of Portugal in perfect order but with no crew on board. Their disappearance has never been explained. Did some of them mutiny and then escape? Were all the crew killed by some unknown agent? Did they try to escape from some danger or other? We shall probably never know. However, regardless of the theories which exist about the "Bermuda Triangle", ships, boats and planes continue to travel daily trough the area with great frequency and it has not been proven that a higher percentage of accidents and losses occur in this section of the North Atlantic than in other areas of the world's oceans.
