初中回顾
知识点一 if条件从句中的虚拟语气
if条件从句 从句的谓语形式 主句的谓语形式及例句
与现在的 事实相反 动词过去式 (be的过去式用were) should/would/could/might+动词原形 We would go with you if we had time. 如果我们有时间,就和你一起去。
与过去的 事实相反 had+过去分词 should/would/could/might+have+过去分词 If you had taken my advice, you would not have failed in the exams. 如果你早听了我的建议,你考试就不会不及格了。
与将来的 事实相反 should+动词原形 should/would/could/might+动词原形 If it should rain this afternoon, the basketball match would be put off. 要是今天下午下雨,篮球比赛就延期举行。
动词过去式
were to+动词原形
知识点二 混合型虚拟语气
混合型虚拟语气中,主句与从句时间上不一致,通常从句为过去时间,主句表示现在的动作或状态。
If you had worked hard yesterday, you would be tired now. 如果你昨天工作很辛苦的话,那你现在就会很疲劳。(从句指过去,主句指现在)
知识点三 虚拟语气的省略和倒装
如果虚拟条件句中含有were/had/should,有时可把if省略,将were/had/should提至主语之前,形
成倒装句;否定形式的not不可提到主语前。
Should it rain tomorrow, we would have to cancel the picnic.如果明天下雨,我们将不得不取消野餐。

衔接点一 含蓄虚拟语气
含蓄虚拟语气中,通常借助介词(短语)without, with, but for(要不是)或者but, otherwise, or等副词或连词。
But for your help, I would not have made great progress.要不是你的帮助,我不会取得如此大的进步。
衔接点二 各种从句中的虚拟
1.虚拟语气在宾语从句中的用法
(1)wish后面的宾语从句一般用虚拟语气,表示一种不可能实现的愿望。其谓语动词构成形式为:
过去时 表示现在不可能实现的愿望
过去完成时 表示过去不可能实现的愿望
could/would/might+动词原形 表示将来不可能实现的愿望
I wish(that) I were a bird and could fly freely in the sky.我希望我是一只小鸟,能在天空自由飞翔。
-How much of the foreign expert's speech have you understood 那个外国专家的演讲你懂了多少?
-Next to nothing. I wish I had worked harder at English.几乎什么也不懂。要是我过去更刻苦学习英语就好了。
(2)表示决定、主张、要求、建议、命令等的动词,如 suggest, recommend, insist, demand, order, require等构成的宾语从句中常用“(should+)do”结构。
(3)would rather后面的宾语从句一般用虚拟语气,表示愿望,意为“宁愿,但愿”。其谓语动词构成形式为:
一般过去时 表示现在或将来的情况
过去完成时 表示过去的情况
George is going to talk about the geography of his country, but I'd rather he focused more on its culture.
乔治将要谈论关于他的国家的地理情况,但是我宁愿他更多地谈论它的文化(方面的情况)。
2.虚拟语气在主语从句中的用法
在It is important/strange/natural/necessary that...句型中,that所引导的主语从句中的谓语动词常用“should+动词原形”,should可以省略。
It is strange that he(should) react in this way. 很奇怪,他竟然做出这样的反应。
3.虚拟语气在It is(high)time(that)...句型中的用法
It is(high/about) time(that)...句型中,谓语动词用过去式,或用should+动词原形(其中should通常不省略)。此句型意为“(现在)该······了”,用来表示提议。
It is(high) time that you went to school. 你该去上学了。
4.as if/as though引导的表语从句和方式状语从句中常用虚拟语气
He stood up and offered her his seat, as if he had read her mind.他站起来给她让座,好像他已经读懂了她的心思。
5.if only引导的感叹句中,常用虚拟语气,表示愿望。意为“要是······就好了”
