单选题Mass transportation revised the social and economic fabric of the American city in three fundamental ways. It catalyzed physical expansion, it sorted out people and land uses, and it accelerated the inherent instability of urban life. By opening vast areas of unoccupied land for residential expansion, the omnibuses, horse railways, commuter trains, and electric trolleys pulled settled regions outward two to four times more distant from city centers than they were inthe premodern era. In 1850, for example, the borders of Boston lay scarcely two miles from the old business district. By the turn of the century the radius extended ten miles. Now those who could afford it could live far removed from the old city center and still commute there for work, shopping, and entertainment. The new accessibility of land around the periphery of almost every major city sparked an explosion of real estate development and pulled what we now know as urban sprawl. Between 1890 and 1920, for example, some 250000 new residential lots were recorded within the borders of Chicago; most of them located in outlying areas. Over the same period, another 550000 were plotted outside the city limits but within the metropolitan area. Anxious to take advantage of the possibilities of commuting, real estate developers added 800000 potential building sits to the Chicago region in just thirty years lots that could have housed five to six million people.

单选题The more time scientists spend designing computers the more they marvel at the human brain. Tasks that baffle (难住) the most advanced supercomputer—recognizing a face, reading a handwritten note—are child's play for the 3-pound organ. Most important, unlike any conventional computer, the brain can learn from its mistakes. Researchers have tried for years to program computers to imitate the brain's abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to function more like a person and less like an over-grown calculator, it must be built more like a brain, which distributes information across a vast interconnected web of nerve cells, or neurons. Conventional computers function by following a chainlike sequence of detailed instructions. Although very fast, their processors can perform only one task at a time. This approach works best in solving problems that can be broken down into simpler logical pieces. The processors in a neural-network computer, by contrast, form a network much like the nerve cells in the brain. Since these artificial neurons are interconnected, they can share information and perform tasks at the same time. This two-dimensional approach works best at recognizing patterns. Instead of programming a neural-network computer to make decisions, its maker trains it to recognize patterns in any solution to a problem by repeatedly feeding examples to the machine. Neural networks come in all shapes and sizes. Until now most exist as software simulations (模拟品) because redesigning computer chips took a lot of time and money. By experimenting with different approaches through software rather than hardware, scientists have been able to avoid costly mistakes.

单选题{{B}}Passage 1{{/B}} The way people hold to the belief that a fun-filled, painfree life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain. As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment (承担的义务), self-improvement. Ask a bachelor (单身汉) why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night's sleep or a three-day vacation. I don't know any parent who would choose the word fun to describe raising children, But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money; buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.
