As we know, most of the material things in our daily life have to be bought with money. But money is not all powerful. Money can't buy many things such as time and true love. There are 24 hours in a day. Sometimes when we are very happy, we wish that the period of happiness would last longer. But no matter what we do, or how much money we are willing to pay, we cannot make a day last longer than 24 hours. On the other hand, when we are unhappy, money cannot make the unhappy time pass away more quickly. True love is another thing which money cannot buy. Suppose we have someone who really loves us very much. Once he dies, he can give us no more love. Can our money raise him from death and make him love us as before? Here we can see very clearly that money cannot buy us love. Money can buy us diamond things, beautiful clothes, but never time and love. So money, after all, is not all powerful.

A. true friendship B. real diamond C. a large house D. an expensive car

解析
Unless we spend money to spot and prevent asteroids 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)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands 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 weapo
ns. But the cost wouldn't be cheap. I
s it 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 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 of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.
