Question

You could have seen Fang Zuming________ yesterday morning.

A．did you come

B．if you came

C．had you come

D．if you should come

Answer 1

C

试题分析：句意：如果你昨天早晨来，你就会看到房祖名。对过去情况的虚拟，条件句中用过去完成时，主句用would/should/might/could + have + 过去分词，虚拟条件句中有had, should, were时，可以将if去掉，然后把had, should, were提到主语前面，选C。
