Question

【题目】–I don’t know what I _______ without the suitcase you lent me.

–Glad to have been of some help to you.

A. should have done B. would do

C. would have done D. should do

Answer 1

【答案】C

【解析】句意：——我不知道如果没有你借给我的提箱，我该怎么做。——很高兴能对你有帮助。根据without判断此处是含蓄型的虚拟语气，根据句意可知此处表示对过去发生事情的推测，故排除BD选项，should have done “本应该做某事”，不符合题意，选C。
