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 meteorites (流星)that race across the night sky. Most 【C1】______ the sun far from Earth and don’t threaten us. But there are also thousands whose orbits put them on a 【C2】______ course with the Earth.
Buy $50 million worth of new telescopes right now. Then spend $10 million a year for the next 25 years to 【C3】______ most of the space rocks. By the time we spot a fatal one, we’ll have a way to change its 【C4】______, the scientists say. Some scientists 【C5】______pushing asteroids off course with nuclear weapons. But the cost wouldn’t be cheap. Is it worth it? Two things experts consider when 【C6】______ any risk are how likely the event is and how bad the 【C7】______ 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 【C8】______ —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. It’s that simple," says one scientist.
The 【C9】______, though, might be worse than the disease. Do we 【C10】______ want fleets of nuclear weapons sitting around on Earth? "The world has less to fear from doomsday rocks than from a great nuclear fleet set against them," said a New York Times article. [br] 【C6】
选项
答案
G
解析
when…any risk部分没有主语,此处应为省略句,承前省略了they are,即“when+分词”的结构,空格填入分词,词库中judging和manipulating可作为备选。风险由专家进行评估,judging符合语义,故选G。行星撞击地球的风险是不可控的,故排除manipulating“操纵”。
