单选题{{B}}Passage Five{{/B}} The most noticeable trend among today's media companies is vertical integration—an attempt to control several related aspects of the media business at once, each part helping the other. Besides publishing magazines and books, Time Warner, for example, owns Home Box Office (HBO), Warner movie studios, various cable TV systems throughout the United States and CNN as well. The Japanese company Matsushita owns MCA Records and Universal Studios, and manufactures broadcast production equipment. To describe the financial status of today's media is also to talk about acquisitions. The media are buying and selling each other in unprecedented numbers, and forming media groups to position themselves in the marketplace to maintain and increase their profits. In 1986, the first time a broadcast network had been sold, two networks were sold that year—ABC and NBC. Media acquisitions have skyrocketed since 1980 for two reasons. The first is that most big corporations today are publicly traded companies, which means that their stock is traded on one of the nation's stock exchanges. This makes acquisitions relatively easy. A media company that wants to buy a publicly owned company can buy that company's stock when the stock becomes available. The open availability of stock in these companies means that anybody with enough money can invest in the American media industries, which is exactly how Rupert Murdoch joined the media business. The second reason for the increase in media alliances is that beginning in 1980, the Federal Communications Commission (FCC) gradually deregulated the broadcast media. Before 1980, for example, the FCC allowed one company to own only five TV stations, five AM radio stations, and five FM radio stations; companies also were required to hold onto a station for three years before the station could be sold. The post-1980 FCC eliminated the three-year rule and raised the number of broadcast holdings allowed for one owner. This trend of media acquisitions is continuing throughout the 1990s, as changing technology expands the market for media products. The issue of media ownership is important. If only a few corporations direct the media industries in this country, the outlets for differing political viewpoints and innovative ideas could be limited.

单选题The United States central bank is prepared to take further actions to support the economy if conditions get a lot worse. Federal Reserve Chairman Ben Bernanke gave that message in a speech in which he discussed possible steps. These include buying more securities in an effort to push down longer-term interest rates and increase economic growth. Mr. Bernanke says it is "reasonable" to expect some increase in economic growth starting next year. Stocks ended the day higher after his speech. It followed a number of reports this week that added to concerns about the slow speed of recovery from the recession. The latest report said the economy was not as bad as many economists had predicted. Many economists say the country needs a growth rate of at least two and a half percent just to keep unemployment from rising. The slowing in GDP largely resulted from a sharp increase in imports. Imports of goods and services increased almost three times as fast in the second quarter as in the first three months of the year. Exports slowed. Not all the reports were bad. The Labor Department said the number of first-time claims for unemployment aid fell for the first time. But more Americans are having trouble making monthly payments on their home loans. Housing helped lead economic recoveries in the past. But this time the housing market not only helped create the recession. Many economists say it is also limiting the recovery. The Commerce Department reported that sales of newly built houses fell to the lowest level since records began in nineteen sixty-three. The National Association of Realtors reported that sales of single-family homes were at their lowest level since records began fifteen years ago. Jed Smith directs research for the association. He says the big drop in sales was largely because of the end of a federal tax credit for first-time homebuyers. According to Jed Smith, "Unemployment is fairly high and people are seared. And when people are scared, or are recovering from being scared, they don"t necessarily run out and buy a house right away."

单选题{{B}}Passage Two{{/B}} According to a survey, which was based on the responses of over 188,000 students, today's traditional-age college freshmen are "more materialistic and less altruistic (利他主义的) than at any time in the 17 years of the poll. Not surprising in these hard times, the students' major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life." It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors in her first year on the job—even before she completed her two-year associate degree. While it's true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions—be the scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run. But the most important argument for a broad education is that in studying the accumulated wisdom of ages, we improve our moral sense. I saw a cartoon recently which shows a group o businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机) : "Miss Baxter," he says, "could you please send in someone who can distinguish right from wrong?" From the long-term point of view, that's what education really ought to be about.
