问题补充:
We the difficulty together, but why didn’t you tell me?
A. should face
B. might face
C. could have faced
D. must have faced
答案:
A. should face
B. might face
(答案→)C. could have faced
D. must have faced
解析:考查情态动词。本题考查对过去事情推测,故用情态动词 + have done,could have done本可以做,must have done过去一定做。句意:我们本可以一起克服困难的,但你为什么不告诉我呢?故C正确。
