Question

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

D

【解析】D考察虛擬語氣。句義：別生我們的氣。我們本來可以和你出去吃飯的。但是當你叫我們的時候，我們正忙著做最好的報告。由we were busy with our final reports when you called in可知，事情發生在過去，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正確。
