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We are told that the mass media are the greatest organs for enlightenment that the world has yet seen; that in Britain, for instance, several million people see each issue of the current affairs program. Panorama. It is true that never in human history were so many people so often and so much exposed to many intimations about societies, forms of life, attitudes other than those which they obtain in their local societies. This kind of exposure may well be a point of departure for acquiring certain important intellectual and imaginative qualities; width of judgment, a sense of the variety of possible attitudes. Yet in itself such exposure does not bring intellectual or imaginative development. It is no more than the masses of stone which lie around in quarry (采石场) and which may, conceivably, go to the making of a cathedral. The mass media cannot build the cathedral, and their way of showing the stone does not always prompt others to build. For the stones are presented within a self-contained and self-sufficient world in which, it is implied, simply to look at them, to observe fleetingly individually interesting points of difference between them, is sufficient in itself. Life is indeed full of problems on which we have to—or feel we should try to—make decisions, as citizens or as private individuals. But neither the real difficulty of these decisions, nor their true and disturbing challenge to each individual, can often be communicated through the mass media. The disinclination to suggest real choice, individual decision, which is to be found in the mass media, is not simply the product of a commercial desire to keep the customers happy. It is within the grain of mass communication. The organs of establishment, however well-intentioned they may be and whatever their form (the State, the Church, voluntary societies, political parties), have a vested interest (既得利益) in ensuring that the public boat is not violently rocked; and will so affect those who work within the mass media that they will be led insensibly towards forms of production which, though they go through the motions of dispute and inquiry, do not break through the skin to where such inquiries might really hurt. They will tend to move, when exposing problems, well within the accepted cliche assumptions of democratic society and will tend neither radically to question these cliches nor to make a disturbing application of them to features of contemporary life. They will stress the "stimulation" the programs give, but this soon becomes an agitation of problems for the sake of the interest of that agitation in itself; they will therefore, again, assist a form of acceptance of the status quo. There are except, ions to this tendency, but they are uncharacteristic.

单选题Reebok executives do not like to hear their stylish athletic shoes called "footwear for yuppies". They contend that Reebok shoes appeal to diverse market segments, especially now that the company offers basketball and children"s shoes for the under-18 set and walking shoes for older customers not interested in aerobics (健身操) or running. The executives also point out that through recent acquisitions they have added hiking boots, dress and casual shoes, and high-performance athletic footwear to their product lines, all of which should attract new and varied groups of customers. Still, despite its emphasis on new markets, Reebok plans few changes in the upmarket (高档消费人群的) retailing network that helped push sales to $1 billion annually, ahead of all other sports shoe marketers. Reebok shoes, which are priced from $27 to $85, will continue to be sold only in better specialty, sporting goods, and department stores, in accordance with the company"s view that consumers judge the quality of the brand by the quality of its distribution. In the past few years, the Massachusetts-based company has imposed limits on the number of its distributors (and the number of shoes supplied to stores), partly out of necessity. At times the unexpected demand for Reebok"s exceeded supply, and the company could barely keep up with orders from the dealers it already had. These fulfillment problems seem to be under control now, but the company is still selective about its distributors. At present, Reebok shoes are available in about five thousand retail stores in the United States. Reebok has already anticipated that walking shoes will be the next fitness-related craze, replacing aerobics shoes the same way its brightly colored, soft leather exercise footwear replaced conventional running shoes. Through product diversification and careful market research, Reebok hopes to avoid the distribution problems Nike came across several years ago, when Nike misjudged the strength of the aerobics shoe craze and was forced to unload huge inventories of running shoes through discount stores.

单选题The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban (禁止) such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights. The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be vulnerable (易受损的) to interference raises the risk that terrorists may use radio system in order to damage navigation equipment. As worrying, though, is the passenger who can't hear the instructions to turn off his radio because the music's too loud.
