　　答案解析

　　31.it 【解析】本句意为‘污染’意思是弄脏——表层土或什么东西，通过引进杂质，这使…不健康或不干净。”显然，此空处应指topsoil or something，因为前面已出现，所以用it来代替。

　　32.taste 【解析】本句意为“我们看得见它，闻得见它，…它，喝它，而且在它中间挣扎。”由常识可知，此空处只有一个“尝”较合适。

　　33.not 【解析】此空前半句意为“我们真地生活在污染中，呼吸着它”，而后半句意为“它开始…我们的健康、幸福和文明。”显然，这是因果关系，故中间的surprisingly前只能加个否定词not。

　　34.threaten 【解析】由33题解析可以知道此空一定为“威胁”之意。

　　35.as 【解析】think of sth.as sth.为固定短语，意为“把某物想成某物”。

　　36.air 【解析】由前面的smog可知，此空处应填与smog相应的物质，又由后面的“hovers over cities”可知，此物质只能是“脏空气”。

　　37.still 【解析】本句意为“但是空气污染，尽管它…是最危险的，但也只是几种攻击最基本生活功能的污染方式之一。”显然，可知此空应填“仍然”。

　　38.which 【解析】由37题解析可知此空应为一个引导定语从句的词，即which，其后的定语修饰“several(types of contamination)”。

　　39.killin9 【解析】本句意为“通过无控制地使用杀虫剂，人类已经污染了土地，…野生动物。”显然，此空处应填“杀害”，但不能填kill，因为英语中无连词时不可能有两个谓语，故应填killing，killing the wildlife是现在分词做伴随状语。

　　40.dumping 【解析】由本句句意“通过将污水和化学物质…入河流和湖泊，…”可知，此空处显然应为“倒”。又因为介词后只能用dumping，而不能用dump。

　　41.drinking 【解析】由本句句意“通过将污水和化学物质倒入河流和湖泊，我们已经污染了我们的…水。”显然，此空处应为“饮用”。
