　　【講解】

　　文中的heavy air pollution就是“空氣重污染”的意思，其中pollution是一個不可數名詞，意思是“污染”，如industrial pollution(工業污染)、water pollution(水污染)、noise pollution(噪音污染)等。形容“嚴重污染”，就可以說heavy pollution。和pollution相關的詞匯還有名詞pollutant(污染物、有害物質)、動詞pollute(污染)、形容詞polluted(受污染的)等。polluted的反義詞是加上否定前綴un-，構成unpolluted(未經污染的)。

　　此外，文中第一段的watchdog是一個名詞，釋義為“監察機關”。
