题目列表(包括答案和解析)

Unless we spend money spotting and preventing asteroids(小行星) now, one might crash into Early 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 is 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 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(世界末日) rocks than from a great nuclear fleet set against it,” said a New York Times article.

9.What does the passage say about asteroids and meteoroids?

A.They are heavenly bodies different in composition.

  B.They are heavenly bodies similar in nature.

C.There are more asteroids than meteoroids.

D.Asteroids are more mysterious than meteoroids.

10.What do scientists say about the collision of an asteroid with Earth?

A.It is very unlikely but the danger exists.

B.Such a collision might occur once every 25 years.

C.Coilisions of smaller asteroids with Earth occur more often than expected.

  D.lt’s still too early to say whether such a collision might occur.

11.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 slove.

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.

12.We can conclude from the passage that .      

A.while pushing asteroids off course nuclear weapons would destroy the world

B.asteroids racing across the night sky are likely to hit Earth in the near future

C.the worry about asteroids can be left to future generations since it is unlike to happen in our    lifetime.

D.workable solutions still have to be found to prevent a collision of asteroids with Earth
