华宇课件网英语四级频道为备考英语四级的同学们整理了2019年12月英语四级语法之虚拟语气(2)，希望可以为大家带来帮助，预祝大家高分通过大学英语四级考试。
虚拟条件句连接词if的省略
如果虚拟条件句的从句中含有were, had, should, could等词时，可以省略连接词if，但这时必须把were, had, should, could等词移到主语前面，形成倒装。这种句型主要用于书面形式。
Were I to do the job, I would finish doing it within two weeks.
Had it not been for his help, we couldn’t have arrived there on time.
Should it rain tomorrow, I would stay at home.
