Unless we spend money to spot and prevent asteroids (小行星) now, one might crash into Earth and destroy life as we know it, say some scientists. Asteroids are bigger versions of the meteoroids (流星) that race across the night sky. Most orbit the sun far from Earth and don’’t threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth. Buy $ 50 million worth of new telescopes right now. then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’’ll have a way to change its course. Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn’’t be cheap. Is it worth it Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare — but if one did fall, it would be the end of the world. "If we don’’t take care of these big asteroids, they’’ll take care of us," says one scientist. "It’’s that simple." The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth "The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them," said a New York Times article. What do scientists say about the collision of an asteroid with Earth
Some people believe that international sport creates goodwill between the nations and that if countries play games together they will learn to live together. Others say that the opposite is true: that international contests encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourage international brotherhood. Not only was there the tragic incident involving the murder of athletes, but the Games were also ruined by lesser incidents caused principally by minor national contests. One country received its second—place medals with visible indignation after the hockey final. There had been noisy scenes at the end of the hockey match as, the losers objecting to the final decisions. They were convinced that one of their go als should not have been disallowed and that their opponents’’ victory was unfair . Their manager was in a rage when he said: "This wasn’’t hockey. Hockey and the International Hockey Federation are finished. " The president of the Federation said later that such behavior could result in the suspension of the team for at least three years. The American basketball team announced that they would not yield first place to Russia, after a disputable end to their contest. The game had ended in disturbance. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player then threw the ball from one end of the court to the other, and another player popped it into the basket. It was the first time the U. S. A. had ever lost an Olympic basketball match. An appeal jury debated the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals. Incidents of this kind will continue as long as sport is played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals, or in non-national terms, might be too much to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive patriotism. What conclusion can be drawn from the passage
