Passage Two
Questions 26 to 30 are based on the following passage:
The rise of multinational corporations（跨国公司）, global marketing, new communications technologies, and shrinking cultural differences have led to an unparalleled increase in global public relations or PR.
Surprisingly, since modern PR was largely an American invention, the U.S. leadership in public relations is being threatened by PR efforts in other countries. Ten years ago, for example, the world’s top five public relations agencies were American-owned. In 1991, only one was. The British in particular are becoming more sophisticated and creative. A recent survey found that more than half of all British companies include PR as part of their corporate（公司的）planning activities, compared to about one-third of U.S. companies. It may not be long before London replaces New York as the capital of PR.
Why is America lagging behind in the global PR race? First, Americans as a whole tend to be fairly provincial and take more of an interest in local affairs. Knowledge of world geography, for example, has never been strong in this country. Secondly, Americans lag behind their European and Asian counterparts（相对应的人）in knowing a second language. Less than 5 percent of Burson-Marshall’s U.S. employees know two languages. Ogilvy and Mather has about the same percentage. Conversely, some European firms have half or more of their employees fluent in a second language. Finally, people involved in PR abroad tend to keep a closer eye on international affairs. In the financial PR area, for instance, most Americans read the Wall Street Journal. Overseas, their counterparts read the Journal as well as the Financial Times of London and The Economist, publications not often read in this country.
Perhaps the PR industry might take a lesson from Ted Turner of CNN(Cable News Network). Turner recently announced that the word “foreign” would no longer be used on CNN news broadcasts. According to Turner, global communications have made the nations of the world so interdependent that there is no longer any such things as foreign.
26. According to the passage, U.S. leadership in public relations is being threatened because of ________.
A) an unparalleled increase in the number of public relations companies
B) shrinking cultural differences and new communications technologies
C) the decreasing number of multinational corporations in the U.S.
D) increased efforts of other countries in public relations.
27. London could soon replace New York as the center of PR because __________.
A) British companies are more ambitious than U.S. companies
B) British companies place more importance on PR than U.S. companies
C) British companies are heavily involved in planning activities
D) four of the world’s top public relations agencies are British-owned
28. The word “provincial” (Line 2, Para.3) most probably means “________”.
A) limited in outlook
B) like people from the provinces
C) rigid in thinking
D) interested in world financial affairs
29. We learn from the third paragraph that employees in the American PR industry ________.
A) speak at least one foreign language fluently
B) are ignorant about world geography
C) are not as sophisticated as their European counterparts
D) enjoy reading a great variety of English business publications
30. What lesson might the PR industry take from Ted Turner of CNN?
A) American PR companies should be more internationally-minded.
B) The American PR industry should develop global communications technologies.
C) People working in PR should be more fluent in foreign languages.
D) People involved in PR should avoid using the word “foreign”.
Passage Three
Questions 31 to 35 are based on the following passage:
Brazil has become one of the developing world’s great successes at reducing population growth-but more by accident than design. While countries such as India have made joint efforts to reduce birth rates, Brazil has had better result without really trying, says George Martine at Harvard.
Brazil’s population growth rate has dropped from 2.99% a year between 1951 and 1960 to 1.93% a year between 1981 and 1990, and Brazilian women now have only 2.7 children on average. Martine says this figure may have fallen still further since 1990, an achievement that makes it the envy of many other Third World countries.
Martine puts it down to, among other things, soap operas（通俗电视连续剧）and installment（分期付款）plans introduced in the 1970s. Both played an important, although indirect, role in lowering the birth rate. Brazil is one of the world’s biggest producers of soap operas. Globo, Brazil’s most popular television network, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy characters living the high life in big cities.
