单选题During the first year that Mr. Wordsworth and I were neighbours, our conversations turned frequently on the two cardinal points of poetry, the power of exciting the sympathy of the reader by a faithful adherence to the truth of nature, and the power of giving the interest of novelty by the modifying colours of imagination. The sudden charm, which accidents of light and shade, which moon-light or sunset diffused over a known and familiar landscape, appeared to represent the practicability of combining both. These are the poetry of nature. The thought suggested itself--(to which of us I do not recollect)--that a series of poems might be composed of two sorts. In the one, the incidents and agents were to he, in part at least, supernatural. And the excellence aimed at was to consist in the interesting of the affections by the dramatic truth of such emotions, as would naturally accompany such situations, supposing them real. And real in this sense they have been to every human being who, from whatever source of delusion, has at any time believed himself under supernatural agency. For the second class, subjects were to be chosen from ordinary life. The characters and incidents were lo be such as will be found in every village and its vicinity, where there is a meditative and feeling mind to seek after them, or to notice them, when they present themselves. In this idea originated the plan of the Lyrical Ballads, in which it was agreed, that my endeavors should be directed to persons and characters supernatural, or at least romantic. Yet so as to transfer from our inward nature a human interest and a semblance of truth sufficient to procure for these shadows of imagination that willing suspension of disbelief for the moment, which constitutes poetic faith. Mr. Wordsworth, on the other hand, was to propose to himself as his object, to give the charm of novelty to things of every day, and to excite a feeling analogous to the supernatural, by awakening the mind's attention to the. lethargy of custom, and directing it to the loveliness and the wonders of the world before us. And inexhaustible treasure, but for which, in consequence of the film of familiarity and selfish solicitude, we have eyes, yet see not, ears that hear not, and hearts that neither feel nor understand.

单选题Microsoft Chairman Bill Gates recently told the nation"s governors that American high school education is "obsolete." He said, "When I compare our high schools to what I see when I"m traveling abroad, I am terrified for our workforce of tomorrow. In 2001, India graduated almost a million more students from college than the United States did. China graduates twice as many students with bachelor"s degrees as the U. S. and has six times as many graduates majoring in engineering. America is falling behind." Gates was describing a global economy in which the chance to move up into a better economic life is slipping overseas, along with jobs that can be performed anywhere—manufacturing in China, technology support in India, online order fulfillment across borders. The Internet brings Bhutan and Bangalore just as close to our offices and living rooms as Boise. Maybe closer. Our children"s competitors are not the other schools in the district or the state or even the nation. They are the technologically literate young people in Taiwan, India, Korea, and other developing nations. For today"s American students, learning and retraining will be a lifelong experience. In The World is Flat , a recent book analyzing the shift in the global economy, Thomas Friedman points out that the dot. com bubble inspired a massive outlay of capital to connect the continents. Undersea cable, universal software, high-tech imagery, and Google have erased geography. College graduates in Latin America, Central Asia, India, China, and Russia can do the information work Americans used to count on—in many cases better and in all cases cheaper. We are burning through reliable careers for our young people at high speed as technology relieves us of the tedium of repetitive work. The robots that vacuum our floors today will be filling our teeth tomorrow. Even jobs at Wal-Mart are endangered. Have you seen the self-check-out lanes? No cashiers required. To be competitive now, U. S. students must develop sophisticated critical thinking and analytical skills to manage the conceptual nature of the work they will do. They will need to be able to recognize patterns, create narrative, and imagine solutions to problems we have yet to discover. They will have to see the big picture and ask the big questions. How many high schools do you know that are nurturing minds like that? Are we supplying the conditions in our schools to create a new crop of original thinkers? Are we making sure our curricula and instructional programs are not relegated for repetitive practice, gathering and organizing information, remediation, and test preparation? Are we requiring all students to use their learning?

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, filling or polishing as many nails as she'd like to, either. Most of her clients spend $12 to $50 weekly, hut 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 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 Deadly, 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 need to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.

单选题{{B}}Passage 2{{/B}} To get from Kathmandu to the tiny village in Nepal, Dave Irvine-Halliday spent more than two days. When he arrived, he found villagers working and reading around battery-powered lamps equipped with light-emitting diodes, or LEDs--the same lamps he had left there in 2000. Irvine-Halliday, an American photonics engineer, was not surprised. He chose to use LED bulbs because they are rugged, portable, long-lived, and, extremely efficient. Each of his lamps produces a useful amount of illumination from just one watt of power. Villagers use them about four hours each night, then top off the battery by pedaling a generator for half an hour. The cool, steady beam is a huge improvement over lamps still common in developing countries. In fact, LEDs have big advantages over familiar incandescent (白炽的) lights as well--so much so that Irvine-Halliday expects LEDs will eventually take over from Thomas Edison's old lightbulb as the world's main source of artificial illumination. The dawn of LEDs began about 40 years ago, but early LEDs produced red or green glows suitable mainly for displays in digital clocks and calculators. A decade ago, engineers invented a semiconductor crystal made of an aluminum compound that produced a much brighter red light. Around the same time, a Japanese engineer developed the first practical blue LED. This small advance had a huge impact because blue, green, and red LEDs can be combined to create most of the colors of the rainbow, just as that in a color television picture. These days, high-intensity color LEDs are showing up everywhere such as the traffic lights. The reasons for the rapid switchover are simple. Incandescent bulbs have to be replaced annually, but LED traffic lights should last five to yen years. LEDs also use 80 to 90 percent less electricity than the conventional signals they replace. Collectively, the new traffic lights save at least 400 million kilowatt-hours a year in the United States. Much bigger savings await if LEDs can supplant Mr. Edison's bulb at the office and in the living room. Creating a white-light LED that is energy-saving, cheap and appealing has proved a tough engineering challenge. But all the major lightbulb makers--including General Electric, Philips, and Osram-Sylvania--are teaming up with semiconductor manufacturers to make it happen.

单选题The study of the relationship between productivity and living standards is significant in that ______.

单选题The tower of Pisa has been leaning so long—nearly 840 years—that it"s natural to assume it will 1 gravity forever. But the famous structure has been in danger of collapsing almost since its first brick was 2 . It began leaning shortly after construction began in 1173. Builders had only reached the third of the tower"s 3 eight stories when its foundation began to settle unevenly on soft soil composed 4 mud, sand and clay. As a result, the structure leaned 5 to the north. Laborers tried to 6 it by making the columns and arches of the third story on the sinking northern side slightly taller. Then political unrest halted construction. The tower sat 7 for nearly 100 years, but it wasn"t done moving. By the time work restarted in 1272, the tower tilted to the south—the 8 it still leans today. Engineers tried to make another 9 , only to have their work interrupted once again in 1278 with just seven stories completed. Unfortunately, the building continued to settle, sometimes at an 10 rate. Finally, between 1360 and 1370, workers finished the project, once again trying to correct the lean 11 angling the eighth story, with its bell room, northward. In 1989, a similarly constructed bell tower in Pavia, Italy, collapsed suddenly. Officials became 12 worried the tower of Pisa would suffer a similar fate that they closed the monument to the 13 . A year later, they rallied together an international team to see 14 the tower could be brought back from the brink. By 2001, the team had decreased the tower"s lean by 44 centimeters, enough to make officials 15 that they could reopen the monument. The actions taken by Burland and his team could, 16 , stabilize the structure forever. The real threat now comes from the masonry itself, especially the material in the 17 stories, where most of the forces caused by the centuries-long leaning have been directed. If any of this masonry crush, the tower could collapse. And even a 18 earthquake in the region could have devastating consequences. After 200 years, another intervention may be required, but the 19 available to make improvements could be far more advanced and 20 the tower for another 800 years.
