填空题A. improved B. accidentally C. until Phrases: A. to keep printing copies 1 they get it B. being 2 deleted from a computer C. as well as 3 computer graphics Twenty years ago when the personal computer hit the business world, experts predicted the advent of the paperless office. But time has proved them wrong. Offices have more paper than ever. People can easily print out a personal copy of a document for anyone who needs to see it. Programs such as spelling and grammar checkers, 4 , have led people to expect perfection in their documents, and 5 . The simple truth is that most people simply prefer paper. Scientific studies have shown that paper copies are easier for people to read and to edit than is text on a screen. And many people are still nervous about documents 6 —if not through their own fault, through a computer system failure or a power outage. In short, although office paper may be significantly reduced, the paperless office is unlikely to become a reality.

填空题A. Benefiting from an earlier modelB. Important operative conditionsC. Examining the public confusionD. How it's all linked upE. Finding a suitable locationF. Comparing wind speeds in Australian citiesG. Matching operational requirements with considerations of appearance Harvest time in Esperance is constant. As long as the wind blows — which is pretty much all the time- nine identical synchronized wind turbines reap the benefits of the dependable winds that gust up around the southern coastline of Western Australia. These sleek, white, robot-like wind turbines loom up on the horizon forming part of Australia's first commercial wind farm. They're not only functional machines that help provide electricity for this secluded coastal town, but increasingly, they're also drawcards for curious tourists and scientists alike. Because of its isolation, Esperance is not linked to Western Power's grid which supplies electricity from gas-, coal- and oil-fired power stations to the widespread population of Western Australia. Before the wind turbines went in, Esperance's entire electricity needs were met by the diesel power station in town. 41. ______ The $5.8 million Ten Mile. Lagoon project is not Esperance's first wind farm. The success of a smaller, experimental wind farm, at a spot called Salmon Beach, encouraged the state's power utility to take Esperance wind seriously. Today, the wind turbines at Ten Mile Lagoon work in conjunction with the diesel power station, significantly reducing the amount of the town's electricity generated by expensive diesel power. 42. ______ The wind farm is connected to the power station by a 33-kilovolt powerline, and a radio link between the two, allows operators to monitor and control each wind turbine. The nine 225-kilowatt Vestas wind turbines produce a total generating capacity of two megawatts and provide around 12 percent of the energy requirements of Esperance and its surrounding districts. 43. ______ The power produced by a wind turbine depends on the size and efficiency of the machine and, of course, on the energy in the wind. The energy in the wind available to the wind turbines is proportional to wind speed cubed. Thus, the greater the wind speed, the greater the output of the turbine. In order to achieve optimum wind speeds, the right location is imperative. "You have to accept the nature of the beast," Mr. Rosser, Western Power's physicist said. "As surface dwellers our perceptions of wind speeds are bad. As you go higher, wind speed increases significantly." 44. ______ The most favorable wind sites are on gently sloping hills, away from obstructions like trees and buildings and where the prevailing winds are not blocked. Computer modeling was used to select the best site for Esperance's wind farm. Scientists were concerned not only with efficiency, but also with protecting the coastal health environment which is rich in plant life and home to tiny pygmy and honey-possums, and a host of bird species. In addition, the wind farm is adjacent to Esperance's popular scenic tourist drive. 45. ______ Strict erosion controls have been implemented and access to the wind farm is limited to selected viewing areas. The wind turbine towers are painted white and devoid of corporate logos or signage. According to Mr. Rosser there is something of a worldwide backlash against wind farms with regard to their visual impact. "But because wind turbines perform best in the most exposed positions, they will always be visible. There is a very real need to balance environmental and technical requirements. I think the Ten Mile Lagoon Wind Farm sets the standards for environmentally friendly developments." In fact, the project has become something of a tourist attraction in itself. Esperance shire president Ian Mickel said the wind turbines had been well accepted by locals. "We have watched the wind farm develop with great interest, and now we find visitors to Esperance are equally enthusiastic about it," he said. The aim now is to identify other remote locations where wind turbines will be a feasible means of supplementing existing power stations.

填空题Say goodbye to the world's tropical glaciers and ice caps. Many will vanish within 20 years. When Lonnie Thompson visited Peru's Quelccaya ice cap in 1977, he couldn't help noticing a school-bus-size boulder that was upended by ice pushing against it. Thompson returned to the same spot last year, and the boulder was still there, but it was lying on its side. The ice that once supported the massive rock had retreated far into the distance, leaving behind a giant lake as it melted away. Foe Thompson, a geologist with Ohio State University's Byrd Polar Research Center, the rolled-back rock was an obvious sign of climate change in the Andes Mountains. "Observing that over 25 years personally really brings it home," he says. "Your don't have to be a believer in global warming to see what's happening. " 41. Thawed ice caps in the tropics. Quelccaya is the largest ice cap in the tropics, but it isn't the only one that is melting, according to decades of research by Thompson's team. NO tropical glaciers are currently known to be advancing, and Thompson predicts that many mountaintops will be completely melted within the next 20 years. 42. Situation in areas other than the tropics. The phenomenon isn't confined to the tropics. Glaciers in Europe, Russia, new Zealand, the United States, and elsewhere are also melting. 43. The worsening effects of global warming. For many scientists, the widespread melt-down is a clear sign that humans are affecting glottal climate, primarily by raising the levels of carbon dioxide and other greenhouse gases in the atmosphere. 44. Receding ice caps. That's not to say that glaciers, currently found on every continent except Australia, haven't melted in the past as a result of natural variability. These rivers of ice exist in a delicate balance between inputs (accumulating snow and ice)and outputs (melting and "calving" of large chunks of ice). Over time, the balance can tilt in either direction, causing glaciers to advance or retreat. What's different now is the speed at which the scales have tipped. "We've been surprised at how rapid the rate of retreat has been," says Thompson. His team began mapping one of the main glaciers flowing out of the Quelccaya ice cap in 1978,using satellite images and ground surveys. 45. Thinning ice cores. And its' not just the margin of the ice cap that is melting. At Qaelccaya and Mount Kilimanjaro, the researchers have found that the ice fields are thinning as well. Besides mapping ice caps and glaciers, Thompson and his colleagues have taken core samples from Queleeaya since 1976, when the ice at the drilling location was 154 meters thick. Thompson and his colleagues have also drilled ice cores from other locations in South America, Africa, and China. Trapped within each of these cores is a climate record spanning more than 8,000 years. It shows that the past 50 years are the warmest in history. The 4-inch-thick ice cores are now stored in freezers at Ohio State. On the future, says Thompson, that may be the only place to see what's left of the glaciers of Africa and Peru.[A] The latest report from the Intergovernmental Panel on Climate Change, prepared by hundreds of scientists and approved by government delegates from more than 100 nations, states: "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities." The report, released in January, says that the planet's average surface temperature increased by about 0.6℃ during the 20th century, and is projected to increase another 1.4 ℃ to 5.8 ℃ by 2100. That rate of warming is "with-out precedent during at least the last 10,000 years," says the IPCC.[B] Alaska's massive Bering and Columbia Glaciers located in nontropical regions, for example, have receded by more than 10 kilometers during the past century. And a study by geologists at the University of Colorado at Boulder predicts that Glacier National Park in Montana, under the influence of melting, will lose all of its glaciers by 2070.[C] For example, about 97 per cent of the planet's water is seawater. Another 2 per cent is locked in icecaps and glaciers. There are also reserves of fresh water under the earth's surface but these are too deep for us to use economically.[D] For example, Africa's Mount Kilimanjaro in tropical areas has lost 82 percent of its ice field since it was first mapped in 1912. That year, Kilimanjaro had 12.1 square kilometers of ice. By last year, the ice covered only 2.2 square kilometers. At the current rate of melting, the snows of Kilimanjaro that Ernest Hemingway wrote about will be gone within 15 years, Thompson estimates. "Butit probably will happen sooner, because the rate is speeding up."[E] "I fully expect to be able to return there in a dozen years or so and see the marks on the rock where our drill bit punched through the ice," says Thompson. If that happens, it will mean that a layer of ice more than 500 feet thick has vanished into thin air.[F] The glacier, Qori Kalis, was then retreating by 4. 9 meters per year. Every time the scientists returned, Qori Kalis was melting faster. Between 1998 and 2000, it was retreating at a rate of 155 meters per years (more than a foot per day), 32 times faster than in 1978. "You can almost sit there and watch it move," says Thompson.

填空题English to Chinese．(西安交通大学2005研，考试科目：基础英语)One of the principal themes of Walzer"s critique of liberal capitalism is that it is insufficiently egalitarian. Walzer"s case against the economic inequality generated by capitalism and in favor of " a radical redistribution of wealth "is presented in a widely cited essay entitled in Defense of Equality.The most striking feature of Walzer"s critique is that far from rejecting the principle of reward according to merit, Walzer insists on its validity. People who excel should receive the superior benefits appropriate to their excellence. But people exhibit a great variety of qualities—"intelligence, physical strength, agility and grace, artistic creative, mechanical skill, leadership, endurance, memory, psychological insight, the capacity for hard work, even moral strength, sensitivity, the ability to express compassion. "Each deserves its proper recompense, and hence a proper distribution of material goods should reflect human differences as measured on all these different scales. Yet under capitalism, the ability to make money("the green thumb of bourgeois society")enables its possessor to acquire almost "every other sort of social good, " such as the respect and esteem of others.
