句子分析:Little has been done to prevent the air from being polluted.
这里的being是不是名词?作定语修饰polluted?

保护空气不受污染的行为作的太少了.

Little has been done to prevent the air from being polluted.
防止空气污染的工作进展甚微。
to prevent the air from being polluted为真正主语

being不是名词,是用来表示polluted的被动形态,air不会自己主动被污染,一定是be polluted,from是介词,后面跟动词要变成ing形式,所以是being pulluted.
防止空气污染的工作做的很少,几乎没有.

being是动名词,但是它不是修饰后面polluted,而是与polluted共同构成被动,受到污染
防止空气(被)污染(至今)未采取什么(具体)措施。
