题型：不详难度：来源：

Don’t be angry with us. We ____ with you together, but we were busy with our final reports when you called in.

A．would eat out	B．must have eaten out
C．should eat out	D．could have eaten out

答案

D

解析

试题分析：考察情态动词用法。本题考察的是情态动词对过去情况的虚拟。must have done是对过去情况的肯定推测“一定做了某事”；could have done本可以做某事，实际上却未做；可能做了某事。句意：不要生我们的气。我们本可以和你一起吃饭的。但是当你打电话的时候，我们忙于准备我们的报告。根据句意说明本句中的could have done本可以做某事，实际上却未做；是一个虚拟语气。故D正确。
点评：本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done 本应该做而实际未做。can’t have done 过去不可能做了某事；shouldn’t have done 本不应该做而实际做了。 need have done 本有必要做某事；needn’t have done 本没有必要做某事；注意没有 mustn’t have done的形式。
