题目
didn’t you
couldn’t you
hadn’t you
shouldn’t you
参考答案和解析
句意：你昨天本来能做得更好，为什么没有做到呢？could have done表示本来能够，但却没有做到。如果用完整的句子是“Why didn’t you do much better yesterday?”省略后为“Why didn’t you?”故为A。

A．I didn't know you did needlework.
B．I think you have done a good job.
C．Where did you learn to do needlework?
D．Why do you do needlework?
解析：选项A中，Mary对Susan会刺绣表示意外，这与Susan的对答“我不常做，只是在特殊时候做一做。”语义相连。对于B的应答应该是礼貌地表示谢意，若选C或D，Susan的回答则显得答非所问。
第7题：
Had you worked harder that time, you ______ a better position.
A. could get

答案为D。如果你在那时更努力些，你本来能得到更好的职位。从句为省略订的非真实条件句，表示与过去情况相反的假设，用过去完成式，因此主语用would+现在完成式。
