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.

单选题The miserable fate of Enron's employees will be a landmark in business history, one of those awful events that everyone agrees must never be allowed to happen again. This urge is understandable and noble: thousands have lost virtually all their retirement savings with the demise of Enron stock. But making sure it never happens again may not be possible, because the sudden impoverishment of those Enron workers represents something even larger than it seems. It's the latest turn in the unwinding of one of the most audacious promise of the 20th century. The promise was assured economic security — even comfort essentially everyone in the developed world. With the explosion of wealth, that began in the 19th century it became possible to think about a possibility no one had dared to dream before. The fear at the center of daily living since caveman days — lack of food warmth, shelter — would at last lose its power to terrify. That remarkable promise became reality in many ways. Governments created welfare systems for anyone in need and separate programs for the elderly(Social Security in the U. S.). Labor unions promised not only better pay for workers but also pensions for retirees. Giant corporations came into being and offered the possibility — in some cases the promise — of lifetime employment plus guaranteed pensions. The cumulative effect was a fundamental change in how millions of people approached life itself, a reversal of attitude that most rank as one of the largest in human history. For millennia the average person's stance toward providing for himself had been. Ultimately I'm on my own. Now it became, ultimately I'll be taken care of... The early hints that this promise might be broken on a large scale came in the 1980s. U. S business had become uncompetitive, globally and began restructuring massively, with huge layoffs. The trend accelerated in the 1990s as the bastions of corporate welfare faced reality. IBM ended its no-layoff policy. AT&T fired thousands, many of whom found such a thing simply incomprehensible, and a few of whom killed themselves. The other supposed guarantors of our economic security were also in decline. Labor -union membership and power fell to their lowest levels in decades. President Clinton signed a historic bill scaling back welfare. Americans realized that Social Security won't provide social security for any of us. A less visible but equally significant trend a affected pensions. To make costs easier to control, companies moved away from defined benefit pension plans, which obligate them to pay out specified amounts years in the future, to define contribution plans, which specify only how much goes into the play today. The most common type of defined-contribution plan is the 401(k). The significance of the 401(k)is that it puts most of the responsibility for a person's economic fate back on the employee. Within limits the employee must decide how much goes into the plan each year and how it gets invested-the two factors that will determine how much it's worth when the employee retires. Which brings us back to Eaton? Those billions of dollars in vaporized retirement savings went in employees' 401(k)accounts. That is, the employees chose how much money to put into those accounts arid then chose bow to invest it. Enron matched a certain proportion of each employee's 401(k)contribution with company stock, so everyone was going to end up with some Eaton ha his or her portfolio, but that could be regarded as a freebie, since nothing compels a company to match employee contributions at all. At least two special features complicate the Eaton case. First, same shareholders charge top management with illegally covering up the company's problems, prompting investors to hang on when they should have sold. Second, Enron's 401(k)accounts were lacked while the company changed plan administrators in October, when the stock was failing, so employees could not have closed their accounts if they wanted to. But by far the largest cause of this human tragedy is that thousands of employees were heavily overweighed in Eaton stock. Many had placed 100% of their 401(k)assets in the stock rather than in the 18 other investment options they were offered. Of course that wasn't prudent, but it's what some of them did. The Enron employees' retirement disaster is part of the larger trend away from guaranteed economic security. That's why preventing such a thing from ever happening again may be impossible. The huge attitudinal shift to I'll-be-taken-care-of took at least a generation. The shift back may take just as long. It won't be complete until a new generation of employees see assured economic comfort as a 20th-century quirk, and understand not just intellectually but in their bones that, like most people in most times and places, they're on their own.

单选题What are those of us who have chosen careers in science and engineering able to do about our current problems? First, we can help destroy the false impression that science and engineering have caused the current world trouble. On the contrary, science and engineering have made vast contributions to better living for more people. Second, we can identify the many areas in which science and technology, more considerably used, can be of great service in the future than in the past to improve the quality of life. While we can make many speeches, and pass many laws, the quality of our environment will be improved only through better knowledge and better application of that knowledge. Third, we can recognize that much of the dissatisfaction we suffer today results from our very successes of former years. We have been so greatly successful in attaining material goals that we are deeply dissatisfied that we cannot attain other goals more rapidly. We have achieved a better life for most people, but we are unhappy that we have not spread it to all people. We have reduced many sources of environmental disasters, but we are unhappy that we have not conquered all of them. It is our raised expectations rather than our failures which now cause our distress. Granted that many of our current problems must be cured more by social, political, and economic instruments than science and technology, yet science and technology must still be the tools to make further advances in such things as clean air, clean water, better transportation, better medical care, more adequate welfare programs, purer food, conservation resources, and many other areas.

单选题Questions 1 to 5 are based on the following passage. The main idea of these business-school academics is appealing. In a word wt ere companies must adapt to new technologies and source of competition, it is much harder than it used to be to often good employees job security and an opportunity to climb the corporate ladder. Yet it is also more necessary than ever for employees to invest in better skills and sparkle with bright ideas. How can firms get the most out of people if they can no longer offer them protection and promotion? Many bosses would love to have an answer. Sumantrra Ghoshal of the London Business School and Christopher Bartlett of the Harvard Business School think they have one: " Employability. " If managers offer the right of training and guidance, and change their attitude towards their underlings, they will be able to reassure their employees that they will always have the skills and experience to find a good job--even if it is with a different company. Unfortunately, they promise more than they deliver. Their thoughts on what an ideal organization should accomplish are hard to quarrel with: encourage people to be creative, make sure the gains from creativity are shared with the pains of the business that can make the most of them, keep the organization from getting stale and so forth The real disappointment comes when they attempt to show how firms might actually create such an environment. At its nub is the notion that companies can attain their elusive goals by changing their implicit contract with individual workers, and treating them as a source of value rather than a cog in a machine. The authors offer a few inspiring example of companies--they include Motorola, 3M and ABB--that have managed to go some way towards creating such organizations. But they offer little useful guidance on how to go about it, and leave the biggest questions unanswered. How do you continuously train people, without diverting them from their everyday job of making the business more profitable? How do you train people to be successful elsewhere while still encouraging them to make big commitments to your own firm? How do you get your newly liberated employees to spend their time on ideas that create value, and not simply on those they enjoy? Most of their answers are platitudinous, and when they are not they are unconvincing.
