求宾语从句中的虚拟语气的过去，现在，将来的句型构成和分别一个例句??？
宾语从句中的虚拟语气，可以分为—— wish后面的宾语从句虚拟语气。
例如 Mary wishes that she would go to a key university.将来 I wish I were a bird!现在 They wish that they had finished their job then.过去 would rather I would rather that it would be fine tomorrow. I would rather that you did not come today. I would rather that I had not said that at the meeting. 要求，建议，明令等动词，后面的宾语从句用should加动词原形虚拟形式，should可以省略。We suggest that a new building be set up in the district.
虚拟语气的用法现在完成时过去完成时？
虚拟语气，从句用过去式，主句would这样的词 动词原形。另外一种，从句用过去完成时，主句用would 现在完成时。就这么简单看就行。
