名师解析

　　这是一篇说明文，文章主要介绍了空气污染的危害性和人们面对空气污染的一些做法。
　　1.B. hundreds of 是一种固定搭配形式。
　　2.C. 文章开头第一句话就告诉我们“The earth is our home”。 它与这句话应该是相互对应的。所以现在人类所污染的也是地球。
　　3.C. 许多年以前，地球上是没有这么多人的。people还是可数名词，因此应该用many 修饰。
　　4.D. others 和the others 都是代词，应该单独使用。the other 特指两者中的另外一个 。another则是多者中的另一个。根据文章的意思，当人们用完一块土地和水资源后，就会迁移到另一个地方去，而地球上有很多地方。所以用another比较合理。
　　5.A. 下面一段介绍的都是空气污染。并且空气污染已经成为当今世界最严重的污染方式。
　　6.C. things 是名词，前面应该用形容词修饰，life和 lives是名词，live是动词。只有living是形容词。
　　7.A. 形容词修饰以thing, body, one结尾的不定代词时应该放在这些不定代词之后。而且被禁止燃烧的应该是不好的东西。
　　8.B. 根据下句“When you are riding, there is no pollution.”可知骑自行车是最好的减少空气污染的方法。
　　9.C. 根据下句“and go to work by car”可知人们还是将自行车放了起来。
　　10.D.“so+形容词或副词+that” 表示“如此……以致于……”。
