单选题Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span. "I think we are knocking at the door of immortality (永生), "said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that's a conservative estimate (保守的估计)." At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology (纳米技术) make it likely that humans will bye in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years." However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death. Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology. Centre. "At present people who could get to that point are not in good health at all./

单选题{{B}}Text 3{{/B}} A curious election will take place in St Louis on April 3rd. Seven candidates will compete for two seats on the city's school board. The polls will open at 6am and stay open until 7pm. Staffing the polling stations and counting the electronic ballots will cost taxpayers at least $260,000. Two happy candidates will celebrate and take office-just in time to have the state of Missouri complete the takeover of the district's schools and give them and the other board members nothing to do for several years. This election to nothing comes after years of falling test scores, revolving superintendents, screaming matches between board members at public meetings and a growing dissatisfaction with every aspect of public education. The state board of education voted on March 22nd to take over the school district, effective in mid-June. Some prominent figures endorsed this course, including the mayor of St Louis, and even some members of the St Louis school board. Others in the city, though, are deeply opposed and ready to fight about it. Although the city schools overall have an amply deserved reputation for low standards, there are some good schools and many good students. The best students have the most to lose, fearing that the turmoil could damage their chances of getting into good universities. When the state education board voted on the takeover, a group of angry students, teachers and other members of the public tried to disrupt the meeting. Protesters are still trying to use the courts to stop the action, and the teachers' union has threatened a strike. Under Missouri law the city's schools will now be placed under a three-member board appointed by the governor, the mayor and the president of the board of aldermen. Governor Matt Blunt's choice of Rick Sullivan, the head of a building firm, has already been attacked because of Mr Sullivan's lack of experience in education and because he lives in one of the wealthiest suburbs outside the city. Mr Sullivan and the other members, who have yet to be appointed, have an almost impossible task before them. The district, which in the past five years has turned a $52m surplus into a $24.5m deficit, has already closed schools, cut services and squeezed spending hard. But as its critics point out, the elected school board still found plenty of money for tours and public relations. The trickle of voters turning out for the pointless board election will pass banners celebrating the new season of the world baseball champions. St Louis has made huge progress in attracting a new generation of young professionals to its downtown area, building new business developments and installing new infrastructure. The great failure in its schools puts all that in danger.

单选题 There has been, in history, a man who was swallowed by a whale and lived to tell the tale. The man's name is James Bartley. The records to prove his unusual experience are in the British Admiralty. Bartley was making his first trip on the whaling ship Star of the East. Suddenly the lookout sighted a huge sperm whale. The whalers knew it was a huge whale by the size of the spray it blew into the air. They lowered their small boats. James Bartley was in the first longboat. The men rowed until they were close to the whale. A harpoon was thrown and it found its mark. It sank into the whale's flesh. The maddened beast crashed into the boat, snapping its tail at the men and the wreckage of their boats. When the survivors were picked up, James Bartley was missing. Shortly before sunset, the whale was finally captured. The sailors tied the whale's dead body to the side of the ship. Because of the hot weather it was important that they cut up the whale fight away. Otherwise, the meat would begin to rot and oil would begin to spoil. When they got to the stomach, they felt something moving about wildly. They thought it would be a big fish still alive inside. But when they opened the stomach they found James Bartley. After this trip, Bartley settled in England, and never returned to sea.

单选题Auctions (拍卖) are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction room to make offers, or "bids", for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of goods. This is called "knocking down the goods, for the bidding ends when the auctioneer bangs a small hammer on a table at which he stands, This is often set on a raised platform called a rostrum. The ancient Romans probably invented sales by auction, and the English word comes from the Latin auction, meaning "increase". The Romans usually sold in this way the spoils taken in war; these sales were called "subusta", meaning "under the spear", a spear being stuck in the ground as a signal for a crowd to gather. In the eighteenth and nineteenth centuries goods were often sold by the candle', a short candle was lit by the auctioneer; and bids could be made while it stayed alight. An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by possible buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a "lot", is usually given a number. The auctioneer need not begin with lot 1 and continue in numerical order; be may wait until he registers the fact that certain dealers arc in the room and then pro- duce the lots they are likely to be interested in. The auctioneer's services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible. Practicaly all goods whose qualities vary are sold by auction. Among these are coffee, hider, skins, wool, tea, cocoa, furs, spices, fruit and vegetables and wines. Auction sales are also usual for land and property, antique, furniture, pictures, rare books, old china, and similar works of art. The auction-rooms at Christie's and Sotheby's in London and New York are world famous.
