A. to return B. returning C. return D. to returning【答案】A【解析】本题考查forget加不定式和动名词的区别。Forget to do表示“忘记曾经做过某事”，事情已经做过；forget doing表示“忘记去做某事”，事情还没做。根据语境“当你见到John 的时候，别忘记把这本书给他”，可知事情还没做，应该用不定式。【例题2】【题干】Do you mind_ me with my work？ A.to help B.help C.helping D.helped【答案】C【解析】本题考查动名词的用法。Mind后跟动名词，表示“介意做某事”，不可以跟不定式。【例题3】【题干】Whats the matter? I am having the trouble _ who has taken my book. A. finding B. looking for C. finding out D. looking up【答案】 C【解析】 “have the trouble”后要用动词的-ing形式。此外，find表示“找到”，强调结果。look for表示“寻找”，强调过程。loop up是“查找(生字、电话号码等)”。find out是“找出来”之意，符合题意要求。四、课堂运用【基础】1.
