e.g. If you succeeded, everything would be all right.

二、在宾语从句中的用法
1. 在动词wish后的宾语从句中, 表示与现在或过去的事实相反, 或对将来的主观愿望, 从句通常省略连词that。
1) 对现在情况的虚拟: 从句动词用过去式或过去进行式 (be动词一般用were) 。
e.g. I wish I were as tall as you.
I wish every day were my birthday.
2) 对过去情况虚拟: 从句动词常用had+过去分词。
e.g. I wish/wished I hadn’t eaten
so much watermelon.
The party was terrible, I wish I had never gone to it.
3) 对将来的主观愿望: 从句动词形式为 would/ could/ might+动词原形。
注意:
主句的主语与从句的主语不能相同,因为主句的主语所期望的从句动作能否实现,取决于从句主语的态度或意愿(非动物名词除外)。
e.g. 但愿你立刻来。
I wish you would come soon.
2. 表示要求,命令,建议的虚拟语气。
一个坚持,两个命令,三个建议,四个要求。这些动词后面的宾语从句要使用虚拟语气。should+动词原形,或将should省略。
