问题描述：

英语选择题（写理由）
---We should do something _______ our environment ______.
A.keeping,cleaned B.to keep,being cleaned C.to keep clean D.keeping,cleaned

答

选B。第一个空不定式TO表示目的第二个空固定词组KEEP DOING 环境是被保持清洁所以是BEING

答

C 动词不定式表示目的，所以排除AD keep sth adj 是个固定短语，clean 可以是形容词。

答

c,do something to do(to do 表示目的)，keep+adj(keep 后加形容词，或doing,这里clean是形容词)

答

应该选c,something是不定代词,不定代词后面要加动词不定式,environment加动词原形
