【讲解】
文中的heavy air pollution就是“空气重污染”的意思，其中pollution是一个不可数名词，意思是“污染”，如industrial pollution(工业污染)、water pollution(水污染)、noise pollution(噪音污染)等。形容“严重污染”，就可以说heavy pollution。和pollution相关的词汇还有名词pollutant(污染物、有害物质)、动词pollute(污染)、形容词polluted(受污染的)等。polluted的反义词是加上否定前缀un-，构成unpolluted(未经污染的)。
此外，文中第一段的watchdog是一个名词，释义为“监察机关”。
