单选题There are four basic types of competition in business that form a continuum from pure competition through monopolistic competition and oligopoly (商品应垄断) to monopoly. At one end of the continuum, pure competition results when every company has a similar product. Companies that deal in commodities such as wheat or corn are often involved in pure competition. In pure competition, it is often the ease and efficiency of distribution that influences purchase. In contrast, in monopolistic competition several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts are often used as part of a marketing strategy to influence sales. Oligopoly occurs when a few companies dominate the sales of a product or service. For example, only five airline carriers control more than 70 percent of all ticket sales in the United States. In oligopoly, serious competition is not considered desirable because it would result in reduced revenue for every company in the group. Although price wars do occur, in which all companies offer substantial savings to customers, a somewhat similar tendency to raise prices simultaneously is also usual. Finally, monopoly occurs when only one firm sells the product. Some monopolies have been tolerated for producers of goods and services that have been considered basic or essential, including electricity and water. In these cases, it is government control, rather than competition, that protects and influences sales.

单选题Today's college students are more narcissistic(自恋的)and self-centered than their predecessors, according to a comprehensive new study by five psychologists who worry that the trend could be harmful to personal relationships and American society. "We need to stop endlessly repeating 'You're special' and having children repeat that back," said the study's lead author, Professor Jean Twenge of San Diego State University. "Kids are self-centered enough already. " "Unfortunately, narcissism can also have very negative consequences for society, including the breakdown of close relationships with others," he said. The study asserts that narcissists "are more likely to have romantic relationships that are short-lived, at risk for infidelity, lack emotional warmth, and to exhibit game-playing, dishonesty, and over-controlling and violent behaviors. " Twenge, the author of Generation Me: Why Today's Young Americans Are More Confident, Assertive , Entitled—and More Miserable Than Ever Before, said narcissists tend to lack empathy, react aggressively to criticism and favor self-promotion over helping others. Some analysts have commended today's young people for increased commitment to volunteer work. But Twenge viewed even this phenomenon skeptically, noting that many high schools require community service and many youths feel pressure to list such endeavors on college applications. Campbell said the narcissism upsurge seemed so pronounced(非常明显的)that he was unsure if there were obvious remedies. "Permissiveness seems to be a component," he said. " A potential antidote would be more authoritative parenting. Less indulgence might be called for. " Yet students, while acknowledging some legitimacy to such findings, don't necessarily accept negative generalizations about their generation. Hanady Kader, a University of Washington senior, said she worked unpaid last summer helping resettle refugees and considers many of her peers to be civic-minded. But she is dismayed(气馁，灰心)by the competitiveness of some students who seem prematurely focused on career status. "We're encouraged a lot to be individuals and go out there and do what you want, and nobody should stand in your way," Kader said. "I can see goals and ambitions getting in the way of other things like relationships. " Kari Dalane, a University of Vermont sophomore, says most of her contemporaries are politically active and not overly self-centered. "People are worried about themselves— but in the sense of where they're going to find a place in the world," she said. "People want to look their best, have a good time, but it doesn't mean they're not concerned about the rest of the world. " Besides, some of the responses on the narcissism test might not be worrisome, Dalane said. "It would be more depressing if people answered, 'No, I'm not special. '"

单选题The mayor threatened to use his ______ over the city council's proposal.

单选题It is a pleasure to see men of a certain age worrying about their weight. Listening to them is not such a pleasure. Because the men are new at the game, they don't hesitate to discuss the fat problem incessantly. However, women of the same age do not discuss the fat problem especially not in mixed company. They prefer to face the problem with quiet dignity. Discussing the problem might only draw attention to some stray body part that may be successfully tucked away under an article of clothing. The age at which a man begins to explore the fat problem can vary. The actual problem can manifest itself in the early 30's, but broad-range discussion usually starts later. There are early nonverbal symptoms. I've watched the rugged journalist who shares my apartment sneak by with a Diet Coke. His shirts are no longer neatly tucked in to display a trim waist. Recently he has begun to verbalize his anxiety. He tells me, with a sheepish grin, that he is taking his suits to Chinatown to have them "tailored". Still-older men have lost their dignity and rattle on unabashedly. Often, wives and children play important roles in their fat-inspection rituals. Take my oldest brother, a former college football player. His daughter says that several times a day he will stand at attention and call out. "Fat medium or thin?" She knows the correct answer medium. Thin would be an obvious stretch, and fat may not get her that new video. According to his wife, he stands in front of the mirror in the morning(before the day's meals take their toll), puts his hands behind his head and lurches into a side bend, then clutches the roll that has developed and says, "Am I getting fatter?" His wife is expected to answer. "You look like you may have lost a few pounds. " And then there are the ex-husbands, a pitiful group. They are extremely vocal. When I go to the movies with one, he confides that he is suffering from great hunger because he is dieting. He hasn't eaten since the pancakes and sausages he wolfed down that morning. He pauses in his monologue while he buys his popcorn. After the movie, we sprint to a restaurant, where he again pauses to devour a basket of bread. Before he orders his chaste salad and soup, he grows plaintive. Do I think he's fat?
