Question

How i wish I ---------with you when you were here last week.

Answer 1

楼主少打一个单词吧?

对“过去”的希望,应该用过去完成时,could have been.

虚拟语气．

wish这个词加宾语从句,通常用虚拟语气．有三种情况．

1．现在的愿望,从句用过去时,如你的例子．

2．过去的愿望,从句用过去完成时,通常是与过去相反的假设．比如

i wish i had seen you yesterday.实际上你没看见

3．将来的愿望,从句用would/could/should/might加动词原形．
