高中虚拟语气所有考点 .

首先,先理解它的含义：虚拟语气(subjunctive mood),表示说的话不是事实,或者是不可能发生的情况,而是一种愿望、建议或与事实相反的假设等.
高中的虚拟语气,主要集中在条件从句、错综时间虚拟句、省略if的虚拟句~下面分开来阐述
关于条件从句：
①与现在事实相反,从句的谓语动词用过去式(be的过去式用were),主句的谓语用should（would,might,could）+动词原形
例 If it were not raining,we should go for a picnic.如果现在不下雨的话,我们就出去野餐了(事实是天在下雨)
②与过去事实相反,从句 是 had+过去分词 ,主句则用 should(would,might,could)+ have done
例 She would have gone to the party if she had been invited要是当初她被邀请的话,她就会去参加这次聚会了(事实是没人邀请她)
③与将来事实相反,从句 是 过去式/were to do/should do ,主句则should(would,might,could) + do
例 If I were to be twenty years old next year,I would take the course of French明年我要是20岁,就去学法语（事实是我已经老了,明年学不了法语了）
关于错综时间虚拟：
通常情况下主句 从句所指时间是一致的,但有时根据上下文语境和明确的时间状语,可指不同时间
例：If I were you,I would have taken his advice(从句现在,主句过去) 我要是你,那时就会听从他的建议
If we hadn't been working hard in the past few years,things would be going smoothly(从句过去,主句现在)
这部分是难点,如果给出明确的时间状语,还容易选择,动词会根据具体的时间作出调整；如果没有明确时间,只能通过语境进行甄别,多做些题练练
关于省略if：
如果虚拟条件句的谓语部分有were,had和should时,可省略if,把were,had和should放到从句主语前面去
例：Had you not helped me,I should have failed.要是没有你的帮助,我就失败了
Were you in my position,you would do the same.假如你处在我的地位,你也会这样干的
Should they attack us,we'll wipe them out completely.加入他们进攻我们,我们就彻底消灭他们
虚拟语气是重难点,不仅在高中,大学的四六级考试也频发出题,我总结的只是高中要点,还有一些其他情况你上大学会遇到.
