单选题{{B}}Passage 1{{/B}} In old days, when a glimpse of stocking was looked upon as something far too shocking to distract the serious work of an office, secretaries were men. Then came the first World War and the male secretaries were replaced by women. A man's secretary became his personal servant, charged with remembering his wife's birthday and buying her presents; taking his suits to the dry-cleaners; telling lies on the telephone to keep people he did not wish to speak to at bay and, of course, typing and filing and taking shorthand. Now all this may be changing again. The microchip and high technology is sweeping the British office, taking with it much of the routine clerical work that secretaries did. "Once office technology takes over generally, the status of the job will rise again because it will involve only the high-powered work and then men will want to do it again." That was said by one of the executives (male) of one of the biggest secretarial agencies in this country. What he has predicted is already under way in the US. One girl described to me a recent temporary job placing men in secretarial jobs in San Francisco. She noted that all the men she dealt with appeared to be gay so possibly that it was just a new twist to the old story. Over here, though, there are men coming onto the job market as secretaries. Classically, girls have learned shorthand and typing and gone into a company to seek their fortune from the bottom-and that's what happened to John Bowman. Although he joined a national grocery chain as secretary to its first woman senior manager, he has since been promoted to an administration job. "I filled in the application form and said I could do audio/typing, and in fact I was the only applicant. The girls were reluctant to work for this young, glamorous new woman with all this power in the firm." "I did typing at school, and then a commercial course. I just thought it would be useful finding a job. I never got any funny treatment from the girls, though I admit I've never met another male secretary. But then I joined the Post Office as a clerk and carelessly played with the typewriter, and wrote letters, and thought that after all secretaries were getting a good ￡21,000 a year more than clerks like me. There was a shortage at that time, you see." "It was simpler working for a woman than for a man. I found she made decisions, she told everybody what she thought, and there was none of that male bitchiness, or that stuff 'ring this number for me dear, ' which men go in for. " "Don't forget, we were a team-that's how I feel about it-not boss and servant but two people doing different things for the same purpose. Once high technology has made the job of secretary less routine, will there be male takeover? Men should beware of thinking that they can walk right into the better jobs. There are a lot of women secretaries who will do the job as well, as they are as efficient and well-trained to cope with word processors and computers as men.

单选题{{B}}Passage One{{/B}} Granted, it's a pretty serious time to be living on this planet. Insane terrorists, political fingerpointing, a string of awful hurricanes, you name it, all filling the headlines with grim reminders that life aren't so peachy. Even reading the smaller stories in national publications seems to indicate that the world is run by gruwnups, and they're busy taking the fun out of everything. The other day I was browsing through one of those magazines that explain serious science news to us dumbbells, and came across an item which announced that two different companies have perfected a pill that contains all the good-for-you stuff found in a glass of red wine and is completely non-alcoholic. Now I'm sure there are other adults out there who, like me, were pleasantly surprised to learn that a little tipple of pinot noir with the roast duckling might not turn one into a slobbering drunk but may actually be beneficial to your health. The news was a single candle, lit in a world of darkness, easing a tiny part of that big rock of guilt we constantly lug uphill. Of course, the minute the news got around, some Italian scientists began putting that age-old innocent beverage through a freeze-drying process that preserved the benefits while removing the alcohol along with all that unnecessary enjoyment. Swell news for teetotalers, but just another indication that our main focus is on getting through each grim day without a moment of relief. Sound far-fetched? Even comic books (a main source of amusement, when I was a tad) have become literary vehicles for philosophical messages. I figure it's all a big plot. Something probably cooked up by mommies and dictators and insurance companies and people who play their boom boxes too loudly. Just to make sure that you and I are prevented from squeezing a dollop of guilt-free enjoyment from a modest amount of fermented grape juice. Mark my words, the next great leap in science won't be in the field of cloning or DNA research or rocket science. What they'll do is develop a way to turn a big juicy standing rib roast into a pinch of tasteless grey protein-packed powder you can sprinkle on a piece of white bread and have for dinner. Remember: just because we're paranoid don't mean they ain't out to get us.

单选题There are four passages in this part After each passage, there are five questions, you are to choose the best answer for each question. The housing market has been for two years propping up consumers' spirits while the rest of the economy lies exhausted on the floor, still trying to struggle to its feet. According to the National Association of Realtors, the national median existing-home price ended the year at $ 164, 000, up 7.1 percent from 2001. That's the strongest annual increase since 1980. Although residential real estate activity makes up less than 8% of total U. S. GDP, a housing market like this one can make the difference between positive and negative growth. Most significantly, consumer spending is 66% of GDP, and the purchase of a new home tends to have an "umbrella effect" on the homeowner's spending as he has to stock it with a washer/dryer, a new big-screen TV, and maybe a swing set for the yard. The main factor in housing's continued strength is a classic economic example of zero-sum boom: the persistent weakness everywhere else. As the 2003 recovery continues to be more forecast than reality. Falling stock prices raised investor appeal for U. S. Treasury Bonds, which in turn, allowed most interest rates to drift even lower. But there are not many signs that there's a bubble ready to burst. December's new record in housing starts, for example, was nicely matched by the new record in new home sales. If you build it, they will buy and even if an economic pickup starts to reduce housing's relative attractiveness, there's no reason why modest economic growth and improved consumer mood can't help sustaining housing's strength. "The momentum gained from low mortgage interest rates will carry strong home sales into 2003, with an improving economy offsetting modestly higher mortgage interest rates as the year progresses," said David Lereah, chief economist at the National Association of Realtors. Just as housing has taken up much of the economic slack for the past two years, both as a comforting investment for fretting consumers and a driver of consumer spending itself, a big bump elsewhere in the economy in 2003 could be housing's downfall. If stocks roar back this spring, capital inflows could steal from the bond market, pushing up long-term interest rates. or Alan Greenspan and the Fed could do the same to short-term rates, as a way to hit the brakes on a recovery that is heating up too fast. In other words, if everything possible goes wrong for housing, homeowners should have plenty to compensate them in terms of job security and income hikes.

单选题One of the many theories about alcoholism is the learning and reinforcement theory, which explains alcoholism by considering alcohol ingestion as a reflex response to some stimulus and as a way to reduce an inner drive state such as fear or anxiety. Characterizing life situations in terms of approach and avoidance, this theory holds that persons tend to be drawn to pleasant situations or repelled by unpleasant ones. In the latter case, alcohol ingestion is said to reduce the tension or feelings of unpleasantness and to replace them with the feeling of euphoria generally observed in most persons after they have consumed one or more drinks. Some experimental evidence tends to show that alcohol reduces fear in an approach-avoidance situation. Conger trained one group of rats to approach a food goal and, using aversive conditioning, trained another group to avoid electric shock. After an injection of alcohol the pull away from the shock was measurably weaker, while the pull toward the food was unchanged. The obvious troubles experienced by alcoholic persons appear to contradict the learning theory in the explanation of alcoholism. The discomfort, pain, and punishment they experience should presumably serve as a deterrent to drinking. The fact that alcoholic persons continue to drink in the face of family discord, loss of employment, illness, and other sequels of repeated bouts is explained by the proximity of the drive reduction to the consumption of alcohol; that is, alcohol has the immediate effect of reducing tension while the unpleasant consequences of drunken behavior come only later. The learning paradigm, therefore, favors the establishment and repetition of the resort to alcohol. In fact, the anxieties and feelings of guilt induced by the consequences of excessive alcohol ingestion may themselves become the signal for another bout of alcohol abuse. The way in which the clue for another bout could be the anxiety itself is explained by the process of stimulus generalization, conditions Or events occurring at the time of reinforcement tend to acquire the characteristics of stimuli. When alcohol is consumed in association with a state of anxiety or fear, the emotional state itself takes on the properties of a stimulus, thus triggering another drinking bout. The role of punishment is becoming increasingly important in formulating a cause of alcoholism based on the principles of learning theory. While punishment may serve to suppress a response, experiments have shown that in some cases it can serve as a reward and reinforce the behavior. Thus if the alcoholic person has learned to drink under conditions of both reward and punishment, either type of condition may precipitate renewed drinking. Ample experimental evidence supports the hypothesis that excessive alcohol consumption can be learned. By gradually increasing the concentration of alcohol in drinking water, psychologists have been able to induce the ingestion of larger amounts of alcohol by an animal than would be normally consumed. Other researchers have been able to achieve similar results by varying the schedule of reinforcement; that is, by requiring the animal to consume larger and larger amounts of the alcohol solutions before rewarding it. In this manner, animals learn to drink enough to become dependent on alcohol in terms of demonstrating withdrawal symptoms.

单选题Social anxiety, in its many forms, is epidemic. Nearly one in four men and one in eight women report high anxiety when going out on a date, while a third of men and almost a half of women report such feelings at dances and discotheques. And the most frequent fear in one survey of 3,000 adults was found to be speaking before a group. "Social anxiety can be the surface sign of much deeper psychological conflicts, such as hidden hostility or guilt," said Seymour Epstein, a clinical psychologist, who has been writing extensively on anxiety and personality. There have long been people who complained of social anxiety, as well those who have sought to cure the problem. Lately there has been a mushrooming of serious research by social psychologists on the topic, and new clinical treatments offered for those who view ordinary social contacts as dangerous and threatening. Not all self-consciousness leads to social anxiety, in the view of Arnold Buss, one of the first psychologists to study the phenomenon. The garden variety self-consciousness, Dr. Buss has written, is simply an introspective awareness of one"s thoughts and feelings. What he calls "public self-consciousness", on the other hand, is a powerful perception of oneself as an object of social scrutiny. The latter is the root of social anxiety. Social anxiety generally creates three different kinds of problems, which can occur separately or in tandem, according to Dr. Cheek. For some people, their social anxiety is primarily cognitive: they suffer from repetitive thoughts expressing their fear of making a poor impression, such as "He must think I am an idiot," or "I cannot think of anything to say." Other people, though, experience their social anxiety almost entirely through physiological symptoms, such as blushing, a pounding heart, or sweating in social situation. In either case, these symptoms lead to a set of behavioral ones: for example, not being able to speak although one wants to, or a general social awkwardness.

单选题This week marks the 10th anniversary of the Alar apple scare, in which many American consumers were driven into a panic following the release of a report by an environmental organization claiming that apples containing the chemical Alar posed a serious health threat to preschoolers. The report was disseminated through a PR (Problem Report) campaign and bypassed any legitimate form of scientific peer re view. Introduced to the American public by CBS "60 Minutes," the unsubstantiated claims in the report led some school districts to remove apples from their school lunch programs and unduly frightened conscientious parents trying to develop good eating habits for their children. Last month, Consumers Union released a report wanting consumers of the perils of consuming many fruits and vegetables that frequently contained "unsafe" levels of pesticide residues. This was especially true for children, they claimed, lake its predecessor 10 years earlier, the Consumers Union report received no legitimate scientific peer review and the public's first exposure to it was through news coverage. Not only does such reporting potentially drive children for consuming healthful fruits and vegetables, the conclusions were based on a misleading interpretation of what constitutes a "safe" level of exposure. Briefly, the authors used values known as the "chronic reference doses," set by the U.S. environmental Protection Agency, as their barometers of safely. Used appropriately, thee levels represent the maximum amount of pesticide that could be consumed daily for life without concern. For a 70-year lifetime, for example, consumers would have to ingest this 'average amount of pesticide every day for more than 25,000 days. It is clear, as the report points out, that there are days on which kids may be exposed to more; it is also clear that there are many more days when exposure is zero. Had the authors more appropriately calculated the cumulative exposures for which the safety standards axe meant to apply, there would have been no risks and no warnings. Parents should feel proud, rather than guilty, of providing fruits and vegetables for their children. It is well established that a diet rich in such foods decreases the risk of heart disease and cancer. Such benefits dramatically overwhelm the theoretical risks of tiny amounts of pesticides in food. So keep serving up the peaches, apples, squash, grapes and pears.
