单选题 Simone de Beauvoir's work greatly influenced Betty Friedan's--indeed, made it possible. Why, then, was it Friedan who became the prophet of women's emancipation in the United States? Political conditions, as well as a certain anti-intellectual bias, prepared Americans and the American media to better receive Friedan's deradicalized and highly pragmatic The Feminine Mystique, published in 1963, than Beauvoir's theoretical reading of women's situation in The Second Sex. In I953 when The Second Sex first appeared in translation in the United States, the country had entered the silent, fearful fortress of the anticommunist McCarthy years (1950--1954), and Beauvoir was suspected of Marxist sympathies. Even The Nation, a generally liberal magazine, warned its readers against "certain political leanings" of the author. Open acknowledgement of the existence of women's oppression was too radical for the United States in the fifties, and Beauvoir's conclusion, that change in women's economic condition, though insufficient by itself, "remains time basic factor" in improving women's situation, was particularly unacceptable.

单选题Why would any woman in her fight mind choose to walk on the balls of her feet with her heels propped up by spikes? The historical answer is that high heels reflect aristocratic tastes-specifically, the tastes of the seventeenth-century French court, which first popularized them in Europe. Not only did heels keep the wearer's feet relatively mud free, they also created a physical elevation to match the social elevation of the stylish, exaggerated the strutting gait of the noble classes, and they suggested, by their very precariousness, that their owners could afford not to worry about falling on their faces. Indeed, as Bernard Rudofsky points out, seventeenth-century wearers of high heels, men and women, frequently had to be transported in sedan chairs because they could not manage cobblestones on foot. Some "heels" in that era were actually full-soled platforms, and to walk on these things at all, one needed the constant elbow support of two Servants. The helplessness associated with the raised-heel style encouraged the notion that heeled persons were above having to care for themselves. In view of this, it is not surprising that even today it is women, almost exclusively, who wear heels. High heels are the cobbler's contribution to what I have called the pedestal ploy. They link physical incapacity with the notion of woman as a "higher being"--too high to get along on her own. Women have taken to high heels, of course, because they feel, correctly, that they increase their attractiveness to men. Part of that increased attractiveness has to do with male fantasies of female fragility. As fashion-iconoclast Elizabeth Hawes puts it, "The idea is that he, in his heavy shoes, should feel stronger and more capable than she on her fragile stilts. Never mind the realities." Another part of it may be biological. In his discussion of rump display among mammals, Dale Guthrie notes that the "lines of the buttocks, thigh, calf and ankle have a native sexual stimulation, but this can be increased with high-heeled shoes; the curves are exaggerated when the heel is lifted." Heels also exaggerate the lateral motion of buttocks the. ultimate function of high heels, therefore, may be to fuel the male belief that women are both impotent and seductive.

单选题Traffic statistics paint a gloomy picture. To help solve their traffic woes, some rapidly growing U.S. cities have simply built more roads. But traffic experts say building more roads is a quick-fix solution that will not alleviated the traffic problem in the long nm. Soaring land costs, increasing concern over social and environmental disruptions caused by road-building, and the likelihood that more roads can only lead to more cars and traffic are powerful factors bearing down on a 1950s-style construction program. The goal of smart-highway technology is to make traffic systems work at optimum efficiency by treating the road and the vehicles traveling on them as an integral transportation system. Proponents of the advanced technology say electronic detection systems, closed-circuit television, radio communication, ramp metering, variable message signing, and other smart-highway technology can now be used at a reasonable cost to improve communication between drivers and the people who monitor traffic. Pathfinder, a Santa Monica, California-based smart-highway project in which a 14-mile stretch of the Santa Monica Freeway, making up what is called a "smart corridor", is being instrumented with buried loops in the pavement. Closed-circuit television cameras survey the flow of traffic, while communication linked to property equipped automobiles advise motorists of the least congested routes or detours. Not all traffic experts, however, look to smart-highway technology as the ultimate solution to traffic gridlock. Some say the high-tech approach is limited and can only offer temporary solutions to a serious problem. "Electronics on the highway addresses just one aspect of the problem: how to regulate traffic more efficiently," explains Michael Renner, senior researcher at the world-watch Institute. "It doesn't deal with the central problem of too many cars for roads that can' t be built fast enough. It sends people the wrong message. They start thinking "Yes, there used to be a traffic congestion problem, but that's been solved now because we have, advanced high-tech system in place." Larson agrees and adds, "Smart highways is just one of the tools that we use to deal with our traffic problems. It 'snot the solution itself, just pan of the package. There are different strategies." Other traffic problem-solving options being studied and experimented with include car pooling, rapid mass-transit systems, staggered or flexible work hours, and road pricing, a system whereby motorists pay a certain amount for the time they use a highway. It seems that we need a new, major thrust to deal with the traffic problems of the next 20 years. There has to be a big change.
