专升本2020年英语备考：虚拟条件句的倒装

很多学生在学习语法中，都会苦恼虚拟语气，这不仅是难点同样也是重点。有的同学其他语法掌握地都很好，但是独独就败在虚拟语气。而且虚拟语气中有个最最最麻烦的语法点，那就是虚拟条件句的倒装。这里，我们就好好讲讲这个语法点
虚拟语气
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，即在从句中be用were代替。
If he were here,everything would be all right.
如果他在这儿，一切都会好的。
If I were you,I would go to look for him.
如果我是你，就会去找他。
典型例题
_____ to do the work,I should do it some other day.
A.If were I B.I were C.Were I D.Was I
答案C.在虚拟条件状语中如果有were,should,had这三个词，通常将if省略，主语提前,变成were,should,had+主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说Were I not to do.,而不能说Weren't I to do.
这个语法复杂多变，想要掌握不是一天两天的事情，在这里点出来时想让大家多多注意，看到虚拟语气时多留点心，说不定能为自己多挣几分。
