问题描述:

15.We should prevent pollution_____happily.
A.from living B.to live
C.living D.to living
为什么是选B,不选A 呢
16.I’m examining the composition he has just
finished_____the possible mistakes in it.
A.to correct B.correct
C.corrected D.correcting
还有这题也是选A,为什么这种题都是选动词不定式,而不选动名词呢。

哎呀,你句子结构没弄清楚
第一个,句意为“我们应该防止污染去生活的更快乐,如果选A就成了使污染快乐的生活了,不和逻辑
第二个,he has just finished是插入语啊,correct不是finished的宾语
知道了吧?
