Question

He didn’t allow ___ in his room, actually he didn’t allow his family ___ at all.

A. to smoke…to smoke B. smoking…to smoke C. to smoke…smoking D. smoking…smoking

Answer 1

1)常搭用动词不定式短语作宾语补足语即，allow sb. to do sth.允许某人做某事
2)只可搭配动名词短语作宾语，不可直接搭用动词不定式作宾补，即只可说 allow doing sth., 不可说allow to do sth
因此应该选B

Answer 2

B. smoking…to smoke

Answer 3

选B非常正确
