问题
选择题
He ______ you more help even though he was very busy.
A.might have given
B.might give
C.may have given
D.may give
答案
答案:A
题目分析:考查虚拟语气:“might have done”可以用来表示“本来有可能做某事,事实上却没做”,表达一种婉转的批评或责备。本题是说“他即使很忙也可能帮助你的(但实际上却并没有)”。因为是谈论过去的事情,情态动词应与不定式的完成式连用,排除B和D。C是对过去事实的推测,与后文不符。选A.
点评:在even if, even though 所引导的让步状语从句中,可用虚拟语气,主句、从句的结构与if所引导的条件从句的各种时态、结构相同。如: Even if he were here himself, he should not know what to do. 即是他亲自来也不知该怎么办。
