虚拟条件句虚拟语气虚拟语气是一种特殊的动词形式,
用来表示说话人所说的话不是一个事实,而是一种假设、猜测、怀疑等(常用在条件状语从句中或让步状语从句中);
表示说话人的愿望、要求、命令、建议等 (常用在名词性从句中)。
简言之,即:不是事实或不大可能发生的事情,就用虚拟语气来表述虚拟语气的概念虚拟语气的常考形式: if 引导的虚拟条件句

should livewould spend注意以下问题:1. 错综时间虚拟条件句
2. (if省略) 倒装虚拟条件句
3. 含蓄条件句虚拟语气If型特例1:错综条件句:定义:从句与主句的动作发生的时间不同If they had studied hard, they could do it easily now.与过去相反与现在相反各自为准1. 错综时间虚拟条件句
即:if虚拟条件句与主句的时间不一致。
1). If you had followed my advice, you would be able to finish the work now.
如果你当时听了我的话,现在就能完成这份工作了。
(从句说明过去,主句说明现在。)
2). If I were you, I would have gone to her birthday party.
如果我是你,我就去参加她的生日晚会了。
(从句说明现在,主句说明过去。)
虚拟语气If型特例2:省略 if 的条件从句:用法:在虚拟条件句中,如果条件句中有were, had(助动词)或should时,可把if省略,把were/ had/should提到主语之前构成倒装,若为否定式,not不可提前。
3. If you had not helped me,I should have failed.2. If he should fail in the experiment this time, he would try again.
