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
