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.

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.

完形填空。

     During my second year of college, I was looking around for a place to live. One Sunday after church, the
pastor (牧师) told me to stay in his daughter's room because his daughter was studying abroad for one year.
     To be   1 , I really didn't want to stay with"the pastor's family". He told me how much the   2 would
be-a very low figure that   3 one home-cooked meal a day. I thought about the   4 and decided to move in.
     At the end of the term I had planned to find   5 living place, since the daughter was to   6 home. To my
delight, they   7 that I share a room with their son. I seemed to have been adopted into their   8   -their people
became my people. I   9 accepted the offer.
     As I emptied the daughter's bedroom, I thought it might be   10 to have a little sister to look after. But
when I later met my new sister, I   11 that she was more independent than I first   12 .
     We finally fell in love,  13  , and have looked after each other for many years. There have been times that
life turned out more  14  than either of us could have known. But we have al- ways been able to go   15
largely because we knew that we are deeply  16 .
     It isn't about marriage-lt's about   17 . It's about mothers and fathers, sisters and brothers and special
friends who are as   18 as family. It's about anybody who can say, "I'll be   19 - you can count on me. I'll
try to look after you and sometimes I will need you to look after me.
     Is there somebody you can depend on? And are others count ing on you? We travel the path of life best
when there is   20 to look after, and when someone is looking after us.
