虚拟语气倒装句.

虚拟条件句的从句部分如果含有were,should,或had,可将if省略,再把were,should或had 移到从句句首,实行倒装.

Were they here now,they could help us.

=If they were here now,they could help us.

Had you come earlier,you would have met him

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

Should it rain,the crops would be saved.

=Were it to rain,the crops would be saved.

注意:在虚拟语气的从句中,动词'be'的过去时态一律用"were",不用was.

If I were you,I would go to look for him.

If he were here,everything would be all right.
