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.

选项
答案
C
解析
空格前的形容词性物主代词its提示空格处应填入名词。下一句的pushing asteroids off course“推离小行星离开原有的轨迹”提示,如果发现致命的小行星,符合逻辑的做法是改变其“运行路线”,不跟地球相撞,词库中的course“线路”符合语境,故选C。
