单选题{{B}}Passage 2{{/B}} One in three Americans said that money was a crucial factor in their decision to work for pay (or have a spouse work) rather than stay home to raise the children, with Baby Boomer women most likely to have made that choice. Forty-five percent of Baby Boomer women—compared with just 32 percent of those 55 and over—said they went to work. "Baby Boomer women, especially the older ones, grew up expecting to replicate the pattern of their mothers' lives," suggests Hochschild. "But then the bills started coming in and more job opportunities opened up, and these women moved into a life they hadn't anticipated." Money played a great role in marriage—even an unhappy one. Approximately 18 percent of all those interviewed said they stayed married because they lacked money to get a divorce, while less than 8 percent said that financial strain in their marriage has caused them to divorce. Lack of money also influenced education choices. Nearly one in four Americans has postponed or decided not to attend college because of financial pressures. Even with the sustained prosperity of the past eight years, Gen-Xers were most likely to have altered their college plans. A 39-year-old Hispanic billing clerk in New York spoke about how the need for money limited her teenager son's ability to take part in extracurricular activities that could increase his chances of getting into college. "Since age 14, my son's been working, and I think he is a superb person. Not having a lot of money has made him realize what work is all about. On the other hand, he was elected to go to a youth leadership conference in Washington, and I can't send him because I don't have the money. Lack of money takes away opportunities he otherwise could have had." On the question of what money can and can't buy, a large majority of Americans said that money could buy "freedom to live as you choose", "excitement in life", and "less stress". In a number of follow-up interviews, many people commented that having extra money would immediately alleviate one source of profound stress—the need to work overtime. Those with college and graduate degrees were far more likely to believe that money can buy freedom, perhaps because better-educated people already have a wider array of choices. College educated professionals, for instance, were much more likely to consider wealth a way of financing travel, starting a business of their own, or funding charitable works in their communities. A 55-year-old Hispanic woman in Los Angeles with a graduate degree and an income of more than $90,000 described a midlife career switch. After resigning from a high-level, high paying— but extremely stressful—civil service job, she became a florist. "After I started tearing my hair out," she said, "I decided to go into business for myself—flowers don't talk back." Can money buy peace of mind? Fifty-two percent of Americans said no. "It all depends on what 'peace' means to you," observed a businesswoman in California who is nearing 60 and would like to retire at 62 and go back to college. "For my husband, peace of mind means working as long as he can and collecting the biggest possible pension. For me, it means knowing I've worked long enough so that I can afford to go after an old dream. I guess you should say that my peace of mind is his worry."

单选题Works of architecture are so much a part of our environment that we accept them as fixed and scarcely notice them until our attention is summoned. People have long known how to enclose space for the many purposes of life. The spatial aspect of the arts is most obvious in architecture. The architect makes groupings of enclosed spaces and enclosing masses, always keeping in mind the function of the structure, its construction and materials, and, of course, its design—the correlative of the other two. We experience architecture both visually and by moving through and around it, so that we perceive architectural space and mass together. The articulation of space and mass in building is expressed graphically in several ways; the principal ones include plans, sections, and elevations. A plan is essentially a map of floor, showing the placement of the masses of a structure and, therefore, the spaces they bound and enclose. A section, like a vertical plan, shows placement of the masses as if the buildings were cut through along a plane, often along a plane that is a major axis of the building. An elevation is a head-on view of an external or internal wall, showing its features and often other elements that would be visible beyond or before the wall. Our response to a building can range from simple contentment to astonishment and awe. Such reactions are products of our experience of a building's function, construction, and design; we react differently to a church, a gymnasium, and an office building. The very movements we must make to experience one building will differ widely and profoundly from the movements required to experience another. These movements will be controlled by the continuity or discontinuity of its axes. For example, in a central plan—one that radiates from a central point, as in the Pantheon in Rome—we perceive the whole spatial entity at once. In the long axial plan of a Christian basilica or a Gothic cathedral, however, our attention tends to focus on a given point—the altar at the eastern end of the nave. Mass and space can be interrelated to produce effects of great complexity, as, for example, in the Byzantine Church of the Katholikon. Thus, our experience of architecture will be the consequence of a great number of material and formal factors, including training, knowledge, and our perceptual and psychological makeup, which function in our experience of any work of art.

单选题When it comes to the slowing economy, Ellen Spero isn't biting her nails just yet. But the 47-year-old manicurist isn't cutting, filing or polishing as many nails as she'd like to, either. Most of her clients spend $12 to $ 50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I'm a good economic indicator," she says. "I provide a service that people can do without when they're concerned about saving some dollars. " So Spero is downscaling, shopping at middle-brow Dillard's department store near her suburban Cleveland home, instead of Neiman Marcus. "I don't know if other clients are going to abandon me, too," she says. Even before Alan Greenspan's admission that America's red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year's pace. But don't sound any alarms just yet. Consumers seem only mildly concerned, not panicked, and many say they remain optimistic about the economy's long-term prospects even as they do some modest belt-tightening. Consumers say they're not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "There's a new gold rush happening in the $ 4 million to $10 million range, predominantly fed by Wall Street bonuses," says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn't mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan's hot new Alain Ducasse restaurant used to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.

单选题 Why does the Foundation concentrate its support on basic rather than applied research? Basic research is the very heart of science, and its cumulative product is the capital of scientific progress, a capital that must be constantly increased as the demands upon it rise. The goal of basic research is understanding, for its own sake. Understanding of the structure of the atom or the nerve cell, the explosion of a spiral nebula or the distribution of cosmic dust, the causes of earthquakes and droughts, or of man as a behaving creature and of the social forces that are created whenever two or more human beings come into contact with one another--the scope is staggering, but the commitment to truth is the same. If the commitment were to a particular result, conflicting evidence might be overlooked or, with the best will in the world, simply not appreciated. Moreover, the practical applications of basic research frequently cannot be anticipated. When Roentgen, the physicist, discovered X-rays, he had no idea of their usefulness to medicine. Applied research, undertaken to solve specific practical problems, has an immediate attractiveness because the results can be seen and enjoyed. For practical reasons, the sums spent on applied research in any country always far exceed those for basic research, and the proportions are more unequal in the less developed countries. Leaving aside the funds devoted to research by industry--which is naturally far more concerned with applied aspects because these increase profits quickly--the funds the U.S. Government allots to basic research currently amount to about 7 percent of its overall research and development funds. Unless adequate safeguards are provided, applied research invariably tends to drive out basic. Then, as Dr. Waterman has pointed out, "Developments will inevitably be undertaken prematurely, career incentives will gravitate strongly toward applied science, and the opportunities for making major scientific discoveries will be lost. Unfortunately, pressures to emphasize new developments, without corresponding emphasis upon pure science tend to degrade the quality of the nation's technology in the long run, rather than to improve it."

单选题Glass (1) Since the Bronze Age, about 3000 B. C., glass has been used for making various kinds of objects. It was first made from a mixture of silica, lime, and an alkali such as soda or potash, and these remained the basic ingredients of glass until the development of lead glass in the seventeenth century. (2) When heated the mixture becomes soft and moldable and can be formed by various techniques into a vast array of shapes and sizes. The homogeneous mass thus formed by melting then cools to create glass, but in contrast to most materials formed in this way (metals, for instance), glass lacks the crystalline structure normally associated with solids, and instead retains the random molecular structure of a liquid. In effect, as molten glass cools, it progressively stiffens until rigid, but does so without setting up a network of interlocking crystals customarily associated with that process. This is why glass shatters so easily when dealt a blow. (3) Another unusual feature of glass is the manner in which its viscosity changes as it turns from a cold substance into a hot, ductile liquid. Unlike metals that flow or "freeze" at specific temperatures, glass progressively softens as the temperature rises, going through varying moldable stages until it flows like a thick syrup. Each of these stages allows the glass to be manipulated into various forms, by different techniques, and if suddenly cooled the object retains the shape achieved at that point. Glass is thus open to a greater number of heat-forming techniques than most other materials.
