   As the development of the society, people live a much better life than before.Because of human's activity, the pollution problem is getting more and more serious,especially the sea pollution.
   As we all know,most of the surface of the earth is covered with water. The seais not only the important part of the climate, but also the home for sea animals and plants.There are too many boats on the sea,and they make loud noise. It makes the fish frightened, so they don't lay eggs. People throw rubbish into the sea, which looks like fish food. When fish eat them, they die.To make things worse, some factories just dump the poisonous waste into the sea. A lot of fish die from the poison.

   你知道太空垃圾吗？当你读这个故事的时候，有很多穿越太空的飞行，这些东西被称为太空垃圾。
   太空垃圾来自许多不同种类的东西，比如旧宇宙飞船。这些东西在太空中传播非常快，我们看不见它们。根据美国国家航空航天局所说，外太空大约有50万件垃圾。这些垃圾碎片中的一些速度大约是每小时28163公里。这甚至可能比宇宙飞船还快。即使是一小片垃圾也能摧毁一艘宇宙飞船或一颗卫星。太空垃圾是个大问题。
  幸运的是，美国宇航局已经找到了解决这个问题的方法。它制造了一颗特殊的卫星，这颗卫星看起来像一个立方体，它的工作是收集小块的太空垃圾。卫星上有一个3D摄像机，它可以发现太空垃圾在哪里，有多大，移动速度有多快。当它靠近太空垃圾时，它用一张网来抓住它。之后，卫星在地球大气层中燃烧太空垃圾。用这种方式，太空垃圾问题就解决了。
