iv. 虚拟语气中的部分倒装句

虚拟语气条件句中省去连词if时，从句主谓部分倒装：

1. 对现在虚拟：Were +主语+其他+虚拟主句

Were I in your place , I wouldn't give up study.

= If I were in your place, I wouldn't give up study.

若是我处你的位置，我决不会放弃学习的。

2. 对过去虚拟：Had +主语+过去分词+虚拟主句

Had you come earlier , you would have met him.

If you had come earlier,you would have met him.

你若早一点来，就会见到他了。

Were it not for your help , I wouldn't have passed the exam.

若不是你的帮助，我考试就不会及格了。

3. 对将来虚拟：Should +主语+动词原型+虚拟主句

Should he do that again , he would be punished.

If he should do that again,he would be punished.

万一他再做那件事，就会受到惩罚。
