单选题{{B}}Text 4{{/B}} According to studies cited by the National Eating Disorders Association, 42 percent of girls in first through third grade want to be thinner, 81 percent of 10-year-olds are afraid of being fat, and 51 percent of 9 and 10-year-old girls feel better about themselves if they are on a diet. In many ways, this fixation on weight at ever earlier ages comes at an inopportune time physiologically. At a recent Hadassah meeting at the Woodlands Community Temple in White Plains, Dr. Marcie Schneider, the director of adolescent medicine at Greenwich Hospital, and Erica Leon, a registered dietitian, spoke about early adolescence as a time when a little bit of pudginess is necessary for proper growth, and youngsters wrestle constantly with their body image. "I can't tell you how many kids I've seen who've been on the Atkins diet, or on the South Beach diet. "Ms. Leon said, adding that overweight children who try diets can be at risk of developing eating disorders. After the presentation, three mothers from Hartsdale who wanted to help their children avoid such issues spoke about how their young daughters are already beginning to become weight-conscious. Anorexia is a mental illness in which the victim eats barely enough to survive, because her distorted thinking makes her think she is fat. Bulimia, a mental illness in which someone binges on large amounts of food, then purges it through vomiting or the abuse of laxatives, is on the rise, and is surfacing in younger and younger patients, mostly girls, said Judy Scheel, the director of the Center for Eating Disorder Recovery in Mount Kisco. About 90 percent of victims of eating disorders are female, and often the male victims are on teams like wrestling and crew, where they must keep their weight low for competitive reasons. Dr. Scheel believes that where girls claim the eating disorder enables them to be thin, boys typically state their goal is to achieve or maintain a muscular but thin physique. The average onset for bulimia used to be 17, but to see teenagers aged 14 and 15 with bulimia is common these days, Dr. Scheel said. Other people believe the disorders have genetic or chemical components, and many people with eating disorders respond well to anti-depressants, for example. A certain amount of education is necessary to help young people avoid becoming obsessed with their body image. " Teachers need to stay outside of talking about diets," Dr. Scheel said, "It's like a parent, always talking about their next diet. You have to help a child understand that if you eat healthily and exercise, your body is going to take care of itself. " And in relatively homogenous populations, like in some Westchester schools, competition runs high. "So the young people don't really see how beautiful diversity is," she said, " and they tend to all be competing for kind of the same goals. "

单选题{{B}}Passage 3{{/B}} If you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; alternatively if you are addressing secretaries, you may want to comment on their disorganized bosses. Here is an example, which I heard at a nurses' convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by St. Peter. He sees wonderful accommodations, beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rashes to the head of the line, grabs his food and stomps over to a table by himself. "Who is that?" the new arrival asked St. Peter. "Oh, that's God," came the reply, "but sometimes he thinks he's a doctor." If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it'll be appropriate for you to make a passing remark about the inedible canteen food or the chairman's notorious bad taste in ties. With other audiences you mustn't attempt to cut in with humor as they will resent an outsider making disparaging remarks about their canteen or their chairman. You will be on safer ground if you stick to scapegoats like the Post Office or the telephone system. If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently off-the-cuff remarks which you can deliver in a relaxed and unforced manner. Often it's the delivery which causes the audience to smile, so speak slowly, and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark. Look for the humor. It often comes from the unexpected. A twist on a familiar quote "If at first you don't succeed, give up" or a play on words or on a situation. Search for exaggeration and understatements. Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.

单选题The biggest danger facing the global airline industry is not the effects of terrorism, war, SARS and economic downturn. It is that these blows, which have helped ground 3 national flag-carriers and force two American airlines into bankruptcy, will divert attention from the inherent weaknesses of aviation, which they have exacerbated. As in the crisis that attended the first Gulf War, many airlines hope that traffic will soon bounce back, and a few catastrophic years will be followed by fuller planes, happier passengers and a return to profitability. Yet the industry"s problems are deeper and older than the trauma of the past two years implies. As the centenary of the first powered flight approached in December, the industry it launched is still remarkably primitive. The car industry, created not long after the Wright Brothers made history, is now a global industry dominated by a dozen firms, at least half of which make good profits. Yet commercial aviation consists of 267 international carders and another 500--plus domestic ones. The world"s biggest carrier, American Airlines, has barely 7% of the global market, whereas the world"s biggest carmaker, General Motors, has (with its associated firms) about a quarter of the world"s automobile market. Aviation has been incompletely deregulated, and in only two markets: America and Europe. Everywhere else deals between governments dictate who flies under what rules. These aims to preserve state-owned national flag-carriers, run for prestige rather than profit. And numerous restrictions on foreign ownership impede cross-border airline mergers. In America, the big network carriers face barriers to exit, which have kept their route networks too large. Trade unions resisting job cuts and Congressmen opposing route closures in their territory conspire to block change. In Europe, liberalization is limited by bilateral deals that prevent, for instance, British Airways (BA) flying to America from Frankfurt or Paris, or Lufthansa offering transatlantic flights from London"s Heathrow. To use the car industry analogy, it is as if only Renaults were allowed to drive on French motorways. In airlines, the optimists are those who think that things are now so bad that the industry has no option but to evolve. Frederick Reid, president of Delta Air Lines, said earlier this year that events since the September 11th attacks are the equivalent of a meteor strike, changing the climate, creating a sort of nuclear winter and leading to a "compressed evolutionary cycle". So how, looking on the bright side, might the industry look after 5 years of accelerated development?

单选题In recent years, railroads have been combining with each other, merging into super systems, causing heightened concerns about monopoly. As recently as 1995, the top four railroads accounted for under 70 percent of the total ton-miles moved by rails. Next year, after a series of mergers are completed, just four railroads will control well over 90 percent of all the freight moved by major rail carriers. Supporters of the new super systems argued that these mergers will allow for substantial cost reductions and better coordinated service. Any threat of monopoly, they argue, is removed by fierce competition from trucks. But many shippers complain that for heavy bulk commodities travelling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat. The vast consolidation within the rail industry means that only one rail company serves most shippers. Railroads typically charge such "captive" shippers 20 to 30 percent more than they do when another railroad is competing for the business. Shippers who feel they are being overcharged have the right to appeal to the federal government’s Surface Transportation Board for rate relief, but the process is expensive, time consuming, and will work only in truly extreme cases. Railroads justify rate discrimination against captive shippers on the grounds that in the long run it reduces everyone"s cost. If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. It’s theory to, which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. "Do we really want railroads to be the arbiters of who wins and who loses in the marketplace?" asks Martin Bercovici, a Washington lawyer who frequently represents shipper. Many captive shippers also worry they will soon be this with a round of huge rate increases. The railroad industry as a whole, despite its brightening fortuning fortunes, still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic. Yet railroads continue to borrow billions to acquire one another, with Wall Street cheering them on. Consider the $ 10.2 billion bid by Norfolk Southern and CSX to acquire Conrail this year. Conrail"s net railway operating income in 1996 was just $ 427 million, less than half of the carrying costs of the transaction. Who"s going to pay for the rest of the bill? Many captive shippers fear that will, as Norfolk Southern and CSX increase their grip on the market.
