题目

Under no circumstances I was warned _________ to give the password to someone else.A.could I B.I could C.I was D.was I
I was to give 这里用法?

答案

句子要倒装,那么首先就把B 、C排除了.就在A、C中选,Under no circumstances I was warned 这部分作的状语,如果把它去掉.A选项句子还原就是I could to give the password to someone else.could 后跟原形,所以错误.D选项还原就是I was to give the password to someone else.这是过去将来时的用法
