单选题Lawn tennis is a good sport, being based on the ancient game of court tennis, which probably came up in Egypt or Persia some 2,500 years ago. Major Walter Wingfield thought that something like court tennis could be played outdoors on lawns, and in December 1873, he introduced his new game, which he called Sphairistike, at a lawn party in Wales. The sport became popular very rapidly, but the strange, difficult name disappeared almost at once, being replaced by the very simple and logical term "lawn tennis". By 1874 the game was being played by British soldiers in Bermuda, and in the early months of that year a young lady named Mary Outerbridge returned from Bermuda to New York, bringing with her the equipment necessary to play the new game. With the help of one of her brothers, she laid out a court on the grounds of the Staten Island Cricket and Baseball Club, and there, in the spring of 1874, Miss Outerbridge and some of her friends played the first game of lawn tennis in the United States. And just two years later, in 1876, the first United States lawn tennis tournament (锦标赛) was held—at Nahant near Boston.

单选题Global energy demand is expected to triple by mid-century. The earth is unlikely to run out of fossil fuels by then, given its vast reserves of coal, but it seems unthinkable that we will continue to use them as we do now. It's not just a question of supply and price, or even of the disease caused by filthy air. The terrorist assault on the World Trade Center raises other scary scenarios: how much easier would it be to crack open the Trans-Alaska pipeline and how much deadlier would it be to bomb a nuclear plant than to attack a wind arm? Skeptics may recall the burst of enthusiasm for conservation and renewable power when oil prices quadrupled in the 1970s. State-funded energy research and development surged, while tax incentives boosted solar, wind and other alternatives to petroleum and the atom. But when oil supplies loosened and prices dropped in the early 1990s, governments lost interest. In the state of California, subsidies evaporated, pushing wind companies into bankruptcy. Clean energy has long way to go. Only 2.2% of the world's energy comes from "new" renewables such as small hydroelectric dams, wind, solar and geothermal. How to boost that share--and at what pace--is debated in industrialized nations--from Japan, which imports 99.7 % of its oil, to Germany, where the nearby Chernobyl accident turned the public against nuclear plants, to the U.S., where the Bush Administration has strong ties to the oil industry. But the momentum toward clean renewables is undeniable. How soon we reach an era of clean, inexhaustible energy depends on technology. Solar and wind energies are intermittent: When the sky is cloudy or the breeze dies down, fossil fuel or nuclear plants must kick into compensate. But scientists are working on better ways to store electricity from renewable sources. While developed nations debate how to fuel their power plants, however, some 1.6 billion people--a quarter of the globe's population--have no access to electricity or gasoline. Many spend their days collecting firewood and cow dung, burning it in primitive stoves that belch smoke into their lungs. To emerge from poverty, they need modern energy. And renewables can help. From village-scale hydropower to household photovoltaic systems to bio-gas stoves that convert dung into fuel. Ultimately, the earth can meet its energy needs without fouling the environment. "But it won't happen," asserts Thomas Johansson, an energy adviser to the United Nations Development Program, "without political will." To begin with, widespread government subsidies for fossil fuels and nuclear energy must be dismantled to level the playing field for renewables. Moreover, government should pressure utility to meet targets for renewable sources of energy.

单选题 Questions6-9 are based on the conversation you have just heard.

单选题Dear Sirs, Your shipment of twelve thousand 'Smart' watches was received by our company this morning. However, we wish to make a number of complaints concerning the serious delay in delivery and your failure to carry out our specific instructions with regard to this order. It was stressed from the beginning that the delivery date had to be less than six weeks from the initial order in order to meet our own customers' requirements. While we understand that delays in production are occasionally inevitable, we must point out that the major reason why the order was placed with your company was because we were assured by you of its speed of delivery, and that your existing stocks were sufficiently high to ensure immediate shipment. Late delivery of the goods has caused US to disappoint several of our most valued customers, and is bound to have a negative effect on potential future orders. The second complaint concerns the difference in color between the watches we ordered and those delivered. It was stated clearly in the original order that watches in combinations of green/purple and orange/purple only were required. However, only half the watches in the delivery received are of the colors specified. Our Hong Kong agent assures US that she stressed to you the importance of following our instructions precisely, since we consider there to be only a limited market in this country for watches of other colors at the present time. Any watches that are not of the specified colors will, of course, be returned to you. We are also somewhat concerned about the rather poor quality of the goods received, since it is apparent that the watches that finally arrived have been produced from inferior materials and have been manufactured to a lower standard than those in the sample. We have also found that a number of the watches do not appear to be functioning. Whether the latter problem is due to poor manufacture, damage during transportation or bad batteries is not yet clear, but we should like to point out that we feel this matter to be entirely your responsibility. As a result of the above problems, therefore, we feel that the most suitable course of action is to return to you unpaid any of the goods considered unsatisfactory, and to subtract any resultant costs from our final settlement. We shall also, of course, be forced to reconsider whether any further orders should be placed with your company. We look forward to your prompt reply. Yours sincerely, John Smith

单选题 Modern technology has put men on the moon and deciphered the human genome. But when it comes to brewing up flu to make vaccines, science still turns to the incredible edible egg. Ever since the 1940s, vaccine makers have grown large batches of virus inside chicken eggs. New cell-based technologies are in the pipeline, and may finally get the support they need now that the United States is faced with a critical shortage of flu vaccine. Although experts disagree on whether new ways of producing vaccine (疫苗) could have prevented a shortage like the one happening today, there is no doubt that the existing system has serious flaws. Each year, vaccine manufacturers place advance orders for millions of specially grown chicken eggs. Meanwhile, Public Health officials monitor circulating strains of flu, and each March they recommend three strains—two influenza A strains and one B strain—for manufacturers to include in vaccines. In the late spring and summer, automated machines inject virus into eggs and later suck out the influenza-rich goop. Virus from the eggs' innards gets killed and processed to remove egg proteins and other contaminants before being packaged into vials for fall shipment. Why has this egg method persisted for six decades? The main reason is that it's reliable. But even though the eggs are reliable, they have serious drawbacks. One is the long lead time needed to order the eggs. That means it's hard to make more vaccine in a hurry, in case of a shortage or unexpected outbreak. And eggs may simply be too cumbersome (大量的) to keep up with the hundreds of millions of doses required to handle the demand for flu vaccine. What's more, some flu strains don't grow well in eggs. Last year, scientists were unable to include the Fujian strain in the vaccine formulation. It was a relatively new strain, and manufacturers simply couldn't ind a quick way to adapt it so that it grew well in eggs. 'We knew the strain was out there,' recalls Theodore Eickhoff of the University of Colorado Health Sciences Center, 'but public-health officials were left without a vaccine—and, consequently, a more severe flu season.' Worse, the viruses that pose the greatest threat might be hardest to grow in eggs. That's because global pandemics like the one that killed over 50 million people between 1918 and 1920 are thought to occur when a bird influenza changes in a way that lets it cross the species barrier and infect humans. Since humans haven't encountered the new virus before, they have little protective immunity. The deadly bird flu circulating in Asia in 1997 and 1998, for example, worried Public Health officials because it spread to some people who handled birds and killed them—although the bug never circulated among humans. But when scientists tried to make vaccine the old-fashioned way, the bird flu quickly killed the eggs. (选自Time)
