Question

【题目】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

Answer 1

【答案】D

【解析】

试题分析：句意：不要对我们生气啦。我们本可以和你一起出去吃饭的，但是你给我们打电话的时候我们正忙于最后的报告。could have done sth.结构表示“本可以做某事”，must have done sth.表示“一定已经做了某事”，故选D.
