Question

Space rubbish is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage（损坏）.

Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.

试题分析:这篇文章主要围绕太空垃圾这一话题

1.B计算题，根据 It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish.可知在太空中有9，000个人造飞行器，30% 是卫星，10%是太空船，剩下的全是太空垃圾，那么可以算出太空垃圾是B.60% 。

2.2】A根据An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage（损坏）.可知这种物品是爆炸产生的，而且4毫米大小，还能敲撞太空船的玻璃并造成损坏，只有A. 碎片 适合。

3.3】A细节理解题，问文章中讲了太空中的几种危害，细读全文可知共讲了两种，一是辐射，二是太空垃圾。

4.4】C选择正确的句子，A科学家已经找到了方法来解决太空中的任何问题，这个句子本身就不正确。B十年内每个人都可以去太空旅行，文章中说的是在不久的将来，C辐射可能危害到太空员的孩子，文中第二段中说明了这一点是正确的，D太空很危险，所以地球人对它没兴趣，这个句子本身也不正确，文章最后一段指出人们对太空很有兴趣。

，总体来说，这篇文章比较简单。
