Unless we spend money to spot（认出，发现） 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（流星体） 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 $500 million worth of new telescopes right now, they 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.
Is it worth it？ Two things experts consider when judging any risk are: （1） How likely the event is; （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（队，车队） of nuclear weapons sitting around on Earth？ “The world has less fear from doomsday rocks than from a great nuclear fleet set against them.” said a New York Times article.

C.Collisions of smaller asteroids with Earth occur more often than expected.
D.It’s still too early to say whether such a collision might occur.
3.What do people think of the suggestion of using nuclear weapons to alter the course of asteroids？
A.It sounds practical but it may not solve the problem.
B.It may create more problems than it might solve.
C.It is a waste of money because a collision of asteroids with Earth is very unlikely.
D.Further research should be done before it is proved applicable.
