虚拟语气时be动词助动词提前表假设有哪几种?
3个回答
1.在虚拟语气的从句谓语中出现 were,should,had 时,可以省略if,同时把这个词放到句首,形成倒装.
如：If I were you,I would not do that.= Were I you,...
If he had known you earlier,things would have been better.= Had I known you...
If you should call on her tomorrow,she would be happy.= Should you call on her...
2.还有一种由be引导的虚拟语气（相当于让步状语从句),在倒装结构中有时会碰到,be动词提前放到从句句首,形成倒装结构.
如：
I'll come as promised,be it rainy or fine.
不论雨天晴天,我都将如约到来.
Everybody must obey the rule,be he a teacher or a student.无论是老师还是学生,人人都必须遵守这个制度.
