wish 后的宾语从句

wish 后的宾语从句中虚拟语气，从句的谓语时态是什么啊？
How she wished his family could go with him.对吗？
书上说根主句时态从句的谓语动词时态应后退一位，怎么理解啊？
请高人耐心指点，本人愚钝！谢谢谢谢谢谢谢谢
那How she wished his family could go with him。是不是错了啊？应该是How she wished his family had gone with him？

就是要比主句的时态往后退一位.比如你这句句子,How she wished his family had gone with him.就是说她是多么希望他的家人和他一起去了.

虚拟语态就是说是假设,其实并没有发生,或者还没有发生的事情.这里主句用了一般过去式,从句的语态就要比主句的语态还要过去,就用过去完成式.

用于wish后面的从句，表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为： 真实状况 wish后 从句动作先于主句动词动作 过去时 过去完成时 （be的过去式为 were） 从句动作与主句动作同时发生 现在时 过去时 （had + 过去分词） 将来不大可能实现的愿望 将来时 would/could + 动词原形 I wish I were as tall as you. 我希望和你一样高。 He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 2）Wish to do表达法。 Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.)

的确虚拟语气中时态应该后退，但是对于wish来说，用法比较固定 she wish he could be well. she wished her friend would get the job. she wished for the peace on earth.
