单选题 The rise of multinational corporations (跨国公司), global marketing, new communications technologies, and shrinking cultural differences have 1ed to an unparalleled increase in global public relations or PR. Surprisingly, since modem 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 irt 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 thing as foreign.

单选题When I was still an architecture student, a teacher told me, "We learn more from buildings that fall down than from buildings that stand up." What he meant was that construction is as much the result of experience as of theory. Although structural design follows established formulas, the actual performance of a building is complicated by the passage of time, the behavior of users, the natural elements--and unnatural events. All are difficult to simulate. Buildings, unlike cars, can't be crash-tasted. The first important lesson of the World Trade Center collapse is that tall buildings can withstand the impact of a large jetliner. The twin towers were supported by 59 perimeter columns on each side. Although about 30 of these columns, extending from four to six floors, were destroyed in each building by the impact, initially both towers remained standing. Even so, the death toll (代价) was appalling--2,235 people lost their lives. I was once asked, how tall buildings should be designed given what we'd learned from the World Trade Center collapse. My answer was, "Lower". The question of when a tall building becomes unsafe is easy to answer. Common aerial fire-fighting ladders in use today are 100 feet high and can reach to about the 10th floor, so fires in buildings up to 10 stories high can be fought from the exterior (外部). Fighting fires and evacuating occupants above that height depend on fire stairs. The taller the building, the longer it will take for firefighters to climb to the scene of the fire. So the simple answer to the safety question is "Lower than 10 stories." Then why don't cities impose lower height limits? A 60-story office building does not have six times as much rentable space as a 10-story building. However, all things being equal, such a building will produce four times more revenue and four times more in property taxes. So cutting building heights would mean cutting city budgets. The most important lesson of the World Trade Center collapse is not that we should stop building tall buildings but that we have misjudged their cost. We did the same thing when we underestimated the cost of hurtling along a highway in a steel box at 70 miles per hour. It took many years before seat beks, air bags, radial tires, and antilock brakes became commonplace. At first, cars simply were too slow to warrant concern. Later, manufacturers resisted these expensive devices, arguing that consumers would not pay for safety. Now we do willingly.

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 turned out that the bread was not dietetic (适合于节食的), 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. Consider fire insurance. Fire insurance maybe 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 orca 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.

单选题An Ohio State University study has linked behavior in young children with the type of job their mother has. Mothers with complex occupations that are self-directed and require working with other people tended to have offspring with relatively low levels of behavior problems. The opposite held true when the jobs were routine, closely supervised, and dealt with things, rather than people. "A job that challenges and interests a mother and gives her an opportunity to exercise judgment and solve problems clearly has positive consequences for her children's behavior," indicates associate professor of sociology Elizabeth Menaghan. Occupations with more positive conditions include management, sales, and teaching positions. Jobs that may be related to increased child behavior problems include book-keeping, food service, and assembly line positions. Women who are supervised closely at work and made to follow strict orders may be more likely to use this same style in raising their kids. They may emphasize obedience to parental authority and the potential for physical punishment. "We believe that the choice of such a parenting style may increase the frequency of behavior problems in children." On the other hand, mothers whose jobs are less controlled by supervisors and who must work closely with other people probably rely less on physical punishment, instead encouraging children to think about consequences of their actions and take responsibility for their behavior. Such an approach encourages youngsters to follow parental demands even when they aren't being supervised because they have accepted parental values as their own. Moreover, mothers whose jobs don't involve constant supervision "develop problem-solving skills that they can bring to other parts of their life". The research also found that those who have more challenging and interesting jobs provide better home environments for their children. The mothers give their offspring more intellectual stimulation and emotional support, and this, in turn, is linked to fewer behavior problems.
