【解析】本文是一篇说明文，主要讲述了地球上的环境污染问题及成因。造成这些污染主要的原因是对空气河流的污染，同时也指出了由于大量使用机动车导致空气污染严重的问题。

1.考查数词的搭配辨析。hundred前面没有冠词后面不能直接搭配years；hundreds of years ago是固定搭配，表示几百年前；不存在hundred of year这个短语；没有hundreds 表示准确数目时不加s。此处含糊的说几百年前，故B选项切题。

2.考查名词词义辨析。Moon月亮；star星星；earth地球；sun太阳。根据“The earth is our home. ”知道本文说的是地球的污染。故C选项切题。

3.考查代词搭配辨析。A lot of或者lots of不能直接用lot；little与lot用法一致，但词义相反；so many修饰可数名词复数；so much修饰不可数名词。此处想要表达之前地球上并没有这么多人，people是集合名词故C选项切题。

4.考查代词搭配辨析。Others指其他许多地方；the others指除去提到的地方以外其他所有地方；the other指两者中的另一个；another指另一个。此处是说如果有地方被污染了人们会去另一个地方，故D选项切题。

5.考查名词词义辨析。Air空气；food食物；water水；noise噪音。由下文“Pollution by SO2 is now the most dangerous kind of air pollution.”可知此处说的是空气污染，故A选项切题。

6.考查形容词词义辨析。For之后加动名词，名词或者代词。Life指生活，生命或者寿命；live指生长，住；living指活的；lives是life的复数形式；此处是说不利于活的事物故C选项切题。

7.考查代词修饰辨析。Something是不定代词修饰不定代词采用后置即something bad。同时此处是说许多国家不让人们燃烧不好的东西，故A选项切题。

8.考查形容词词义辨析。Least最少的，最小的；best最好的；most最多的；worst最坏的；此处是说人们认为骑自行车的一个最好的办法。故B选项切题。

9.考查动词短语辨析。Put on穿上，上演，增加；look at看；put away放好，抛弃，储存；look up向上看。此处是说人们抛弃骑自行车而是选择开车的事情。故C选项切题。

10.考查副词辨析。Suite是一套；such如此形容名词；very非常；so修饰形容词或者副词。此空后是形容词故D选项切题。

【名师点睛】学生在做完形填空的时候，一定要注意上下文的暗示，多多联系上下文语境，不要追求速度而盲目下结论，并且对于短语的固定搭配一定要记牢。

完型填空主要考察的是词义辨析，形容词，动词，副词，介词，名词，连词以及动词短语等。1.掌握好意义相近的词的区别是做好完型填空的一大关键。
2.增加词汇量是提高做题速度的重要方法。
3.很大一部分完型填空的内容是故事性的，与生活实际相联系能够提高正确率。
4.牢记常用固定搭配及常用句型句式可以提高正确率和效率。

例如: 如第2题考察名词词义辨析。从文章中可推知本文说的是地球的污染，故选C。

第9小题考查的固定短语搭配，结合前后文及其句意，当看到选项时便能瞬时确定选项。此处是说人们抛弃骑自行车而是选择开车的事情。
