问题补充:
We the difficulty together, but why didn 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:考察情态动词。本题可采取排除法做题,but之后内容为过去时,因此前面空格部分所写内容应与过去相关,排除A、B两个选项。而D项表示对过去事实的肯定推测,与didn you tell me不符。could have done表示过去本能做的事情却没有做。句意:我们本能一起面对困难的,你(那时)为什么不告诉我?
