People usually devise tools to (22) for natural deficiencies. For example, people invented weapons to defend (23) from physically superior (24) .But (25) is only one incentive for inventions. People also invent (26) tools to (27) certain established tasks more efficiently. For instance, people developed the bow and arrow from the (28) spear or javelin in order to shoot (29) and strike with greater strength. (30) civilizations developed, greater work efficiency came to be demanded, and (31) tools became more (32) .A、tool would (33) a function until it proved (34) in meeting human needs, at which point an improvement would be made. One impetus for invention has always been the (35) for speed and high-quality results--provided they are achieved (36) reasonable costs. Stone pebbles were sufficient to account for small quantities of possessions, (37) they were not efficient enough for performing sophisticated mathematics. However, beads arranged systematically evolved into the abacus.

| 第4题：{{B}}Text 3{{/B}} Mostly, this explosive growth has occurred democratically. The online penetration and computer ownership increases extend across all the demographic levels-by race, geography, income, and education. We view these trends as favorable without the slightest question because we clearly see computer technology as empowering. In fact, personal growth and a prosperous U.S. economy are considered to be the long-range rewards of individual and collective technological power. Now for the not-so-good news. The government’s analysis spells out so-called digital divide. That is, the digital explosion is not booming at the same pace for everyone. Yes, it is true that we are all plugged in to a much greater degree than any of us have been in the past.But some of us are more plugged in than others and are getting plugged in far more rapidly.And this gap is widening even as the pace of the information age accelerates through society. Computer ownership and Internet access are highly classified along lines of wealth, race, education, and geography. The data indicates that computer ownership and online access are growing more rapidly among the most prosperous and well educated: essentially, wealthy white people with high school and college diplomas and who are part of stable, two-parent households. The highest income bracket households, those earning more than $75,000 annually, are 20 times as likely to have access to the Internet as households at the lowest income levels, under $10, 000 annually. The computer penetration rate at the high-income level is an amazing 76.56 percent, compared with 8 percent at the bottom end of the scale. Technology access differs widely by educational level.College graduates are 16 times as likely to be Internet surfers at home as are those with only elementary-school education. If you look at the differences between these groups in rural areas, the gap widens to a twenty-six-fold advantage for the college-educateD、 From the time of the last study, the information access gap grew by 29 percent between the highest and lowest income groups, and by 25 percent between the highest and lowest education levels. In the long run, participation in the information age may not be a zero sum game, where if some groups win, others must lose.Eventually, as the technology matures we are likely to see penetration levels approach all groups equally. This was true for telephone access and television ownership, but eventually can be cold comfort in an era when tomorrow is rapidly different from today and unrecognizable compared with yesterday. |
B．Poor education and low-income level.
C．Participation in the information age.
D．Telephone access and television ownership.
| 第5题：Whether you think the human story begins in a garden in Mesopotamia known asEden, or in present-day eastAfrica, it is clear that human beings did not start life as an urban creature. Man’s habitat at the outset was dominated by the need to find food, and hunting and gathering were rural pursuits. Not until around 11,000 years ago, did he start building anything that might be called a village. It took another 6000 years for cities of more than 100,000 people to develop. In terms of human history this may seem a welcome development. It would be questionable to say that nothing of consequence has ever come out of the countryside. The wheel was presumably a rural invention.Even city-dwellers need bread as well as circuses.And ifDr. Johnson and Shelley were right to say that poets are the true legislators of mankind, then all those hills and lakes and other rural delights must be given credit for inspiring them. But the rural contribution to human progress seems slight compared with the urban one.Cities’ development is synonymous with human development. The first villages came with the emergence of agriculture and the domestication of animals: people no longer had to wander but could instead draw together in settlements, allowing some to develop particular skills.After a while the farmers could produce surpluses, and the various products could be exchangeD、 Living together meant security.But people also drew together for the practical advantages of being in a particular place: by a river or spring, on a defensible hill or peninsula, next to an estuary (the mouth of a river) or other source of fooD、Also important, argue historians, was a settlement’s capacity to draw people to it as a meeting-place, often for sacred or spiritual purposes. Graves, groves, even caves might become places for ceremonies and rituals. Man did not live by bread alone. But bread, in the broadest sense, was important. People came to cities not just to worship but to trade and the goods they bought and sold were not just farm products but the manufactures of urban craftsmen and skilled workers. The city became a centre of exchange, both of goods and of ideas, and so it also became a centre of learning, and innovation. Cities were much more than all of this, of course, and they were not all the same.As they developed, some were most notable for their religious role, as the hub of an empire, as centres of administration, political development, learning, or commerce. Some flourished, some died, their longevity depending on factors as varied as conquest, plague, misgovernment or economic collapse. By saying "Man did not live by bread alone" (Line 6, Paragraph 4), the author means______. [A] people needed to eat a variety of food [B] men often lived beside food sources [C] men ought to live a more noble life [D] besides food, there were other pursuits for men |
