Question

He ______ you more help even though he was very busy.

1. A.
   might have given
2. B.
   might give
3. C.
   may have given
4. D.
   may give

Answer 1

A
解析：

试题分析：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.
考点：考查虚拟语气
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。
