为帮助大家顺利通过英语四级考试，本文为各位考生整理了英语四级语法的相关内容，希望能够助大家一臂之力，具体内容如下：

省略连词IF的虚拟条件句要倒装

若虚拟条件句中含有were或had，should等助动词或情态动词时，连词if可以省略,将were, had, should提到前面。

【例如】

Had I left a little earlier, I would have caught the train.

Were this to happen, it would cause a great deal of damage. Should it rain tomorrow, we would cancel the trip.____right now, she would get there on Sunday. (CET-4 1996,6)

A) Would she leave

B) If she leaves

C) Were she to leave

D) If she had left

根据主从句的时态搭配，可以判断是对将来的虚拟，条件从句省略了if，助动词提前，故答案为C。
