单选题The Chinese have used a method called acupuncture (针灸) to perform operations for about 4 000 years without putting the patient to sleep. This involves placing flexible needles into certain parts of the body. The needles are available in a number of stores in China and anyone may buy them. To learn how to use the needles takes about one month of training. But to be skillful requires greater time. The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. A particular operation might require 25 or more needles placed in various parts of the body. But now this operation requires only 3 or 4 needles. Today, the Chinese doctors are trying to learn more about acupuncture. They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a needle in the wrist, for example, would prevent the pain in the area of the mouth. A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep. It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation, and because the chemical may make the patient sick for a few hours or a day.

单选题{{B}}Passage Four{{/B}} As soon as it was revealed that a reporter for progressive magazine had discovered bow to make a hydrogen bomb, a group of firearm(火器) fans formed the National Hydrogen Bomb Association, and they are now lobbying against any legislation to stop Americans from owning one. "The Constitution," said the associationes spokesman, "gives everyone the right to own arms. It doesn't spell out what kind of arms. But since anyone can now make a hydmgen bomb, the public should be able to buy it to protect theraselves." "Don't you think it's dangerous to have one in the house, particularly where there are children around?" "The National Hydrogen Bomb Association hopes to educate people in the safe handling of this type of weapon. We are instrueting owners to keep the bomb in a locked cabinet and the fuse(导火索) separately in a drawer." "Some people consider the hydrogen bomb a very fatal weapon which could kill somebody." The spokesman said, "Hydrogen bombs don't kill people--people kill people. The bomb is for selfpro-tection and it also has a deterrent effect. If somebody knows you have a nuelear weapon in your house, they're going to think twice about breaking in." "But those who want to ban the bomb for American citizens claim that if you have one locked in the cabinet, with the fuse in a drawer, you would never be able to assemble it in time to stop an intruder(侵入者)." "Another argument against allowing people to own a bomb is that at the moment it is very expensive to build one So what your association is backing is a program which would allow the middle and upper classes to acquire a bomb while poor people will be left defenseless with just handguns."

单选题{{B}}16-20{{/B}} Two main techniques have been used for training elephants, which we may call respectively the tough and the gentle. The former method simply consists of setting an elephant to work and beating him until he does what is expected. Apart from any moral considerations this is a stupid method of training, for it produces a resentful animal who at a later stage may well turn man-killer. The gentle method requires more patience in the early stages, but produces a cheerful, good-tempered elephant who will give many years of loyal service. The first essential in elephant training is to assign to the animal a single mahout who will be entirely responsible for the job. Elephants like to have one master just as dogs do, and are capable of a considerable degree of personal affection. There are even stories of half-trained elephant calves who have refused to feed and pained to death when by some unavoidable circumstance they have been deprived of their own trainer. Such extreme cases must probably be taken with a grain of salt, but they do underline the general principle that the relationship between elephant and mahout is the key to successful training. The most economical age to capture an elephant for training is between fifteen and twenty years, for it is then almost ready to undertake heavy work and can begin to earn its keep straight away. But animals of this age do not easily become subservient to man, and a very firm hand must be employed in the early stages. The captive elephant, still roped to a tree, plunges and screams every time a man approaches, and for several days will probably refuse all food through anger and fear. Sometimes a tame elephant is tethered nearby to give the wild one confidence, and in most cases the captive gradually quietens down and begins to accept its food. The next stage is to get the elephant to the training establishment, a ticklish business which is achieved with the aid of two tame elephants roped to the captive on either side. When several elephants are being trained at one time, it is customary for the new arrival to be placed between the stalls of two captives whose training is already well advanced. It is then left completely undisturbed with plenty of food and water so that it can absorb the atmosphere of its new home and see that nothing particularly alarming is happening to its companions when it is eating normally, its own training begins. The trainer stands in front of the elephant holding a long stick with a sharp metal point. Two assistants, mounted on tame elephants, control the captive from either side, while others rub their hands over his skin to the accompaniment of a monotonous and soothing chant. This is supposed to induce pleasurable sensations in the elephant, and its effects are reinforced by the use of endearing epithets, such as 'ho! my son', or 'ho! My father', or 'my mother' according to the age and sex of the captive. The elephant is not immediately susceptible to such blandishments, however, and usually lashes fiercely with its trunk in all directions. These movements are controlled by the trainer with the metal-pointed stick, and the trunk eventually becomes so sore that the elephant curls it up and seldom afterwards uses it for offensive purposes.

单选题{{B}}Text 3{{/B}} Today, the computer has taken up appliance status in more than 42 percent of households across the United States. And these computers are increasingly being wired to the Internet. Online access was up more than 50 percent in just the past year. Now, more than one quarter of all U.S. households can surf in cyberspace. Mostly, this explosive growth has occurred democratically. The online penetration and computer ownership increases extend across all the demographic levels-by race, geography, income, and education. We view these trends as favorable without the slightest question because we clearly see computer technology as empowering. In fact, personal growth and a prosperous U.S. economy are considered to be the long-range rewards of individual and collective technological power. Now for the not-so-good news. The government's analysis spells out so-called digital divide. That is, the digital explosion is not booming at the same pace for everyone. Yes, it is true that we are all plugged in to a much greater degree than any of us have been in the past. But some of us are more plugged in than others and are getting plugged in far more rapidly. And this gap is widening even as the pace of the information age accelerates through society. Computer ownership and Internet access are highly classified along lines of wealth, race, education, and geography. The data indicates that computer ownership and online access are growing more rapidly among the most prosperous and well educated: essentially, wealthy white people with high school and college diplomas and who are part of stable, two-parent households. The highest income bracket households, those earning more than $75,000 annually, are 20 times as likely to have access to the Internet as households at the lowest income levels, under $10, 000 annually. The computer penetration rate at the high-income level is an amazing 76.56 percent, compared with 8 percent at the bottom end of the scale. Technology access differs widely by educational level. College graduates are 16 times as likely to be Internet surfers at home as are those with only elementary-school education. If you look at the differences between these groups in rural areas, the gap widens to a twenty-six-fold advantage for the college-educated. From the time of the last study, the information access gap grew by 29 percent between the highest and lowest income groups, and by 25 percent between the highest and lowest education levels. In the long run, participation in the information age may not be a zero sum game, where if some groups win, others must lose. Eventually, as the technology matures we are likely to see penetration levels approach all groups equally. This was true for telephone access and television ownership, but eventually can be cold comfort in an era when tomorrow is rapidly different from today and unrecognizable compared with yesterday.

单选题{{B}}21-25{{/B}} The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people's desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers' money. Sometimes advertising is intentionally misleading. A few years ago a brand of bread was offered to turned out that the bread was not dietetic (适合于节食的) , but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf. On the positive side, emotional appeals may respond to a consumer's real concerns. Consider fire insurance. Fire insurance maybe sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising. Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it? Advertising is intended to appeal to consumers, but it does not force them to buy the product. Consumers still control the final buying decision.

单选题It is easier to negotiate initial salary requirement because once you are inside, the organizational constraints (约束) influence wage increases. One thing, however, is certain: your chances of getting the raise you feel you deserve are less if you don"t at least ask for it. Men tend to ask for more, and they get more, and this holds true with other resources, not just pay increases. Consider Beth"s story: I did not get what I wanted when I did not ask for it. We had cubicle (小隔间) offices and window offices. I sat in the cubicles with several male colleagues. One by one they were moved into window offices, while I remained in the cubicles. Several males who were hired after me also went to offices. One in particular told me he was next in line for an office and that it had been part of his negotiations for the job. I guess they thought me content to stay in the cubicles since I did not voice my opinion either way. It would be nice if we all received automatic pay increases equal to our merit, but "nice" isn"t a quality attributed to most organizations. If you feel you deserve a significant raise in pay, you"ll probably have to ask for it. Performance is your best bargaining chip (筹码) when you are seeking a raise. You must be able to demonstrate that you deserve a raise. Timing is also a good bargaining chip. If you can give your boss something he or she needs (a new client or a sizable contract, for example) just before merit pay decisions are being made, you are more likely to get the raise you want. Use information as a bargaining chip too. Find out what you are worth on the open market. What will someone else pay for your services? Go into the negotiations prepared to place your chips on the table at the appropriate time and prepared to use communication style to guide the direction of the interaction. (345 words)
