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. Fast food, a mainstay of American eating for decades, may have reached a plateau in the United States as the maturing baby-boom generation looks for a more varied menu. Fast food still represents a .$ 102 billion a year industry, but growth has turned sluggish recently amid tough competition from retail food stores and a more affluent population willing to try new things and spend more, analysts say. Signs of trouble in fast food include price-cutting by industry leaders, including efforts by McDonald's to attract customers with a 55 cent hamburger, and major players pulling out or selling. O'Pepsico, for example, is selling its fast-food restaurant division that includes Taco Bell, Pizza Hut and KFC. "It's becoming harder and harder for these firms to grow," said Jim Brown, a professor of marketing at Virginia Tech University. "I think in the United States fast food has reached a saturation (饱和) point because of the number of competitors and the number of outlets." Fast-food restaurant revenues grew 2. 5 percent in 1996, according to industry figures, the slowest since the recession of 1991. That is for cry from(大不相同于)the levels of the 1970s and 1980s. According to the Food Marketing Institute, consumers are using supermarkets for 21 percent of take-home food, nearly double the level of a year ago. While fast-food restaurants still lead, their share slipped significantly, from 48 percent in 1996 to 41 percent in 1997. "Consumers have never been more demanding than they are today," said Michael Sansolo, senior vice president of the Supermarket Trade Group. "They are pressed for time. Money is still an issue…but their tastes are increasingly diverse--whether it's gourmet foods, ethnic foods or organic offerings." Meanwhile, the aging of the baby-boom population--and the growth in the number of so-called "empty nesters" with grown children--has meant a surge in the number of people willing to spend more for upscale items. This generation "will have the luxury of being more discriminating" as their children leave home, notes Harry Balzer, vice president of the Chicago-based NPD consulting group. Balzer said some 18 million baby boomers will become empty-nesters in the next l 0 years, leaving them with more disposable income to spend on dining out. "Fast and cheap will still be driving factors.., but our definitions of fast and cheap may be changing." Various reports suggest industry leader McDonald's is struggling, losing market share, with lower same-store sales while cutting back the number of new outlets in the United States, partly due to pressure from franchisers who don't want to be squeezed. The company replaced the head of its 12,000 US restaurant chain last October amid a slump in US market share.

单选题 The newspaper must provide for the reader the facts, unalloyed, unsalted, objectively selected facts. But in these days of complex news it must provide more; it must supply interpretation, the meaning of the facts. This is the most important assignment confronting American journalism—to make clear to the reader the problems of the day, to make international news as understandable as community news, to recognize that there is no longer any such thing (with the possible exception of such scribbling as society and club news) as "local" news, because any event in the international area has a local reaction in manpower draft, in economic strain, in terms, indeed, of our very way of life. There is in journalism a widespread view that when you embark on interpretation, you are entering choppy and dangerous waters, the swirling tides of opinion. This is nonsense. The opponents of interpretation insist that the writer and the editor shall confine himself to the "facts". This insistence raises two questions: What arc the facts? And: Are the bare facts enough ? As to the first query, consider how a so-called" factual" story comes about. The reporter collects, say, fifty facts; out of these fifty, his space allotment being necessarily restricted, he selects the ten which he considers the most important. This is Judgment Number One. Then he or his editor decides which of these ten facts shall constitute the lead of the piece. ( This is an important decision because many readers do not proceed beyond the first paragraph. ) This is Judgment Number Two. Then the night editor determines whether the article shall be presented on page one, where it has a large impact, or on page twenty-four, where it has little. Judgment Number Three. Thus, in the presentation of a so-called" factual" or" objective" story, at least three judgments are involved. And they are judgments not at all unlike those involved in interpretation, in which reporter and editor, calling upon their research resources, their general background, and their "news neutralism", arrive at a conclusion as to the significance of the news. The two areas of judgment, presentation of the news and its interpretation, are both objective rather than subjective processes—as objective, that is, as any human being can be (Note in passing: even though complete objectivity can never be achieved, nevertheless the ideal must always be the beacon on the murky news channels. ) If an editor is intent on slanting the news, he can do it in other ways and more effectively than by interpretation. He can do it by the selection of those facts that prop up his particular plea. Or he can do it by the play he gives a story -- promoting it to page one or demoting it to page thirty.
