单选题After a 300 million yuan renovation project, Lidai Diwang Miao, or the Imperial Temple of Emperors of Successive Dynasties, was reopened to the public last weekend. Originally constructed about 470 years ago, during the reign of Emperor Jiajing of the Ming Dynasty, the temple was used by emperors of both the Ming and Qing to offer sacrifices to their ancestors. It underwent two periods of renovation in the Qing Dynasty, during the reigns of emperors Yongzheng and Qianlong. From 1929 until early 2000, it was part of Beijing No. 159 Middle School. The temple's Jingdechongsheng Hall contains stone tablets memorializing 188 Chinese emperors. The jinzhuan bricks used to pave the floor, the same as those used in the Forbidden City, are finely textured and golden-yellow in color. According to Xi Wei, an official from the Xicheng District government present at the reopening of the temple, jinzhuan bricks were made in Yuyao, Suzhou, specially for imperial use. The renovation was done strictly according to that carried our at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been replaced.

单选题Attention to detail is something everyone can and should do—especially in a tight job market. Bob Crossley, a human-resources expert notices this in the job applications that come across his desk every day. "It"s amazing how many candidates eliminate themselves. " he says. "Resume (简历) arrive with stains. Some candidates don"t bother to spell the company"s name correctly. Once I see a mistake, I eliminate the candidate," Crossley concludes. "If they cannot take of these details, why should we trust them with a job?" Can we pay too much attention to detail? Absolutely. Perfectionists struggle over little things at the cost of something larger they work toward. "To keep from losing the forest for the trees," says Charles Garfield, associate professor at the University of California, San Francisco. "We must constantly ask ourselves how the details we"re working on fit into the larger picture. If they don"t, we should drop them and move to something else." Garfield compares this process to his work as a computer scientist at NASA. "The Apollo II moon launch was slightly off-course 90 percent of the time. " says Garfield, "But a successful landing was still likely because we knew the exact coordinates of our goal. This allowed us to make adjustments as necessary. " Knowing where we want to go helps us judge the importance of every task we undertake. Too often we believe what accounts for others" success is some special secret or a lucky break (机遇). But rarely is success so mysterious. Again and again, we see that by doing little things within our grasp well, large rewards follow. (271 words)

单选题 The ocean bottom a region nearly 2.5 times greater than the total land area of the Earth is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible, bidden beneath waters averaging over 3 600 meters deep. Totally without light and Subjected to intense pressures hundreds of times greater than at the Earth's surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space. Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation's Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP's drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean's surface and drill in very deep waters, extracting samples of sediments and rocks from the ocean floor. The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600 000 kilometers and took almost 20 000 core samples of seabed sediments and rocks at 624 drilling sites around' the world. The Glomar Challenger's core samples have allowed geologists to reconstruct what the planet looked like hundred of millions of years ago and to calculate what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger's voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth. The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world's past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change information that may be used to predict future climates.

单选题{{B}}Text 3{{/B}} Today, the computer has taken up appliance status in more than 42 percent of households across the United States. And these computers are increasingly being wired to the Internet. Online access was up more than 50 percent in just the past year. Now, more than one quarter of all U.S. households can surf in cyberspace. 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.
