【題目】 Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.

According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望遠(yuǎn)鏡). There are also millions of smaller pieces of junk that we can't see.

Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle (交通工具).

To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.

"The time to act is now. The longer we leave the problem, the bigger it will become," he says.

【答案】

1outer space

3To reduce additional space junk./ In order to reduce additional space junk.

4Many scientists are also suggesting different ways to clean up space junk.

5我們把這個(gè)問題擱置的時(shí)間越長,它就會(huì)變得越大。

【解析】

本文大意: 許多人知道垃圾是地球上的一個(gè)大問題。 很多人不知道的是,垃圾在外太空已經(jīng)成為一個(gè)問題。

1細(xì)節(jié)理解題,根據(jù)第一段What many people don't know is that junk has become a problem in outer space too. 可知,垃圾在外太空已經(jīng)成為一個(gè)問題。故答案為outer space。

2根據(jù)If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle (交通工具).可知, 如果最小的一塊垃圾撞上太空船,它可能會(huì)損壞交通工具。故答案為It would damage the vehicle.

3根據(jù)To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. 可知,為了減少額外的太空垃圾。故答案為To reduce additional space junk./ In order to reduce additional space junk.

4段落大意題,一般一句話的主題句通常在第一句或者最后一句,根據(jù)第六段的內(nèi)容 In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. 可知, 許多科學(xué)家也建議用不同的方法來清理太空垃圾。故第一句是本段的主題句。故答案為Many scientists are also suggesting different ways to clean up space junk.

5翻譯題,the longer…...the bigger…...越長…..越大……,we我們;leave留下,丟下;the problem這個(gè)問題;become成為。故答案為我們把這個(gè)問題擱置的時(shí)間越長,它就會(huì)變得越大。
