单选题For years and years people have been saying that the railways arc dead. "We can do without railways," people say, as if motorcars and planes have made the railways unnecessary. We all keep hearing that trains are slow, that they lose money, and that they are dying. But this is far from the truth. In those days of expensive oil, the railways have become highly competitive with motorcars and planes. If you want to carry people or goods from place to place, they are cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. What is more, it takes from the heart of a city into the heart of another. It doesn't leave you as a plane does, miles and miles from the city center. It doesn't hold you up as a car does, in endless traffic jams. And a single train can carry goods which a plane or motorcar could never do. Far from being dead, the railways are very much alive. Modern railway lines give you a smooth, untroubled journey. Where else can you eat well, sleep in comfort, feel safe and enjoy the scene while you are traveling at speed at the same time? And we are only at the beginning. For we have just entered the age of super fast trains, trains traveling at 150 miles an hour and more. Soon we will be wondering why we spent so much on motorcars we can't use because we have not enough money to buy the oil and planes we can't fly for the same reason.

单选题 Generations of Americans have been brought up to believe that a good breakfast is one of life's essentials. Eating breakfast at the start of the day, we have all been old, and told again, is as necessary as putting gasoline in the family car before starting a trip. But for many people the thought o? food first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1997and 1983 ,the latest year for which figures are available, the number of people who didn't have breakfast increased by 33 percent-from 8.8 million to 11.7 million-according to the Chicago-based market Research Corporation of America. For those who feel pain of guilt about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast. Going without breakfast does not affect performance, said Arnold E. Bender, the former professor of nutrition at Queen Elizabeth College in London, nor does giving people breakfast improve performance. Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most of the recent work involves children, not adults. The literature, says one researcher, Dr Emesto Pollitt at the University of Texas," is poor".

单选题 Eye contact is a nonverbal technique that helps the speaker "sell" his or her ideas to an audience. Besides its persuasive powers, eye contact helps hold listener interest. A successful speaker must maintain eye contact with an audience. To have a good relation with listeners, a speaker should maintain direct eye contact for at least 75 percent of the time. Some speakers focus exclusively on their notes. Others gaze over the heads of their listeners. Both are likely to lose audiences' interest and esteem. People who maintain eye contact while speaking, whether from a podium (演讲台) or from across the table, are "regarded not only as exceptionally well disposed by their target but also as more believable and earnest". To show the potency of eye contact in daily life, we have only to consider how passers- by behave when their glances happen to meet on the street. At one extreme are those people who feel obliged to smile when they make eye contact. At the other extreme are those who feel awkward and immediately look away. To make eye contact, it seems, is to make a certain link with someone. Eye contact with an audience also lets a speaker know and monitor the listeners. It is, in fact, essential for analyzing an audience during a speech. Visual cues (暗示) from audience members can indicate that a speech is dragging, that the speaker is dwelling on a particular point for too long, or that a particular point requires further explanation. As we have pointed out, visual feedback from listeners should play an important role in shaping a speech as it is delivered.

单选题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 dieters (节食者) with the message that there were fewer calories (热量单位，卡路里) in every slice. It turned out that the bread was not dietetic (适合节食的), 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, considering fire insurance. Fire insurance may be 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.
