题目内容
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 |
D
D考察虚拟语气。句义:别生我们的气。我们本来可以和你出去吃饭的。但是当你叫我们的时候,我们正忙着做最好的报告。由we were busy with our final reports when you called in可知,事情发生在过去,首先排除AC。Must have eaten out一定出去吃了;could have eaten out一定出去吃了。Could have eaten out原本可以出去吃。故D正确。
