It just may be the world’s most costly vacuum cleaner (吸塵器). The price of CleanSpace One is eleven million dollars. But yet, it has a big job to do. Recently, researchers in Switzerland said they planned to build this new cleaning machine.

CleanSpace One will not be for use in homes or businesses. It will be shot into space to help remove thousands of pieces of space junk floating around up there.

Last year, we reported on the problem of space junk. Over time, many unused spacecraft have hit each other far above the Earth. Big pieces break into thousands of small pieces. Sometimes they fall back into the atmosphere (大氣層) and burn up. But when they do not, it creates big problems.

Scientists fear that if something is not done to remove these objects, it may soon become too dangerous to send people and machines into space. There is a large chance that they might hit some of this junk. So that is why the Swiss researchers are developing the new machine.

CleanSpace One is not really a vacuum cleaner. It will not be used to take away space junk. But scientists plan to move it close to an old satellite that is no longer being used. Then a claw-like instrument will catch the satellite, and force it back through the atmosphere. There, the satellite will be destroyed by the heat of friction (摩擦) with the air.

Researchers say that all they need to do is slow down the speed of some of these unwanted objects. Once they begin to move more slowly, they will fall back to the Earth. There is little chance that they will fall through the atmosphere and harm the people or things below.

1.Space junk is created when ____________.

A. unused spacecraft hit each other

B. people in space throw away rubbish

C. a new spaceship is sent up

D. an old spaceship creates friction with the air

2.What’s the danger of space junk?

A. It will pollute space. B. It will hurt people on the Earth.

C. It will hit a spaceship. D. It will burn in the atmosphere.

3.Unwanted objects will fall back to the Earth when _______ .

A. they are made to move slowly B. they meet other objects in space

C. they are not used for years D. they are near the atmosphere

I grew up in a house where the TV was seldom turned on and with one wall in my bedroom entirely lined with bookshelves, most of my childhood was spent on books I could get hold of. In fact, I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (觀點(diǎn)) by creating worlds we could step into, take part. in. and live in.

With this unshakable belief, I, at fourteen, decided to become a writer. Here too, reading became useful. Every writer starts off knowing that he has something to say, but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with, or agrees with so strongly that it reshapes his own world. He cannot write without loving to read, because only through reading other people's writing can one discover what works, what doesn't and, in the end, together with lots of practice, what voice he has.

Now I am in college, and have come to realize how important it is to read fiction (文學(xué)作品).As a law student, my reading is in fact limited to subject matter-the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it all the clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road, all from the comfort of my own armchair, to experience, though secondhand, exciting experiences that I wouldn't necessarily be able to have in my lifetime.

1.What can be inferred about the author as a child?

A. He never watched TV. B. He read what he had to.

C. He found reading unbelievable. D. He considered reading part of his life.

2.The underlined word "voice" in the second paragraph most probably means "_______".

A. an idea B. a sound quality

C. a way of writing D. a world to write about

3.What effect does reading have on the author?

A. It helps him to realize his dream.

B. It opens up a wider world for him.

C. It makes his college life more interesting.

D. It increases his interest in worldwide travel.

4.. Which of the following can be the best title of this text?

A. What do I read? B. How do I read?

C. Why do I read? D. When do I read?
