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
D
解析
空格前The提示空格处应填入名词。上文提到科学家提出将小行星推离原有运行轨迹,避免撞地球的建议,词库中的名词cure“(解决问题的)对策”能概括科学家的提议,且能跟空格后的disease相呼应,故选D。
