高中英语虚拟语气知识点

英语虚拟语气知识1

主句:主语+ should/would/might/could+动词原形

如果我是你,我就会带把伞。(事实:我不是你)

如果我知道他的电话号码,我就会告诉你。(事实:不知道)

表示与将来事实相反

从句:①if+主语+were to do

②if+主语+should+do

③if+主语+动词一般过去式(be动词用were)

主句:

主语+should/would/might/could+do

If he should come here tomorrow,I would talk to him.

如果他明天来这儿的话,我就跟他谈谈。(事实:来的可能性很小,不可能)

If there were a heavy snow next Sunday,we would go skating.

如果下周日下大雪,我们就去滑冰。(事实:下雪可能性很小,不可能)

If she were to be here next Monday,I would tell her about the matter.

如果她下周一来这儿的话,我就会告诉她这件事的始末。(事实:来的可能性很小,不可能)

除了以上三种主要情况,虚拟语气还有以下几种结构和用法:

当从句的谓语动词含有were/should/had时,if可以省略,这时从句要用倒装语序,即把were/should/had等词置于句首,这种多用于书面语。

Should he speak fluent English, we would send him there.

要是能说流利的英语的话,我们就派他去了。

Were she here, she would agree with us.(If she were here...)

如果她在这儿的话,她会同意我们的。

有些条件句只暗含在副词、介词短语、上下文或其他方式表示出来,这种情况也要用虚拟语气。

在多数情况下,条件会暗含在短语中,如without…/but for…(要不是因为...)等。

But for his help,we would be working now.

要不是他的帮助,我们还会在工作呢。

We would have come home safely it were not for your kindness.

如果不是你的慷慨心善,我们是不可能安全回家的。

Without your instruction,I would not have made such great progress.

要是没有你的指导,我不会取得如此大的进步。

有时,虚拟语气的结构中,主、从句可以省略其中的一个,来表示说话人的一种强烈的感情。

省略从句

He would have finished it(if...).

他本该完成了。

You could have passed this exam(if...).

你本来能通过这次考试的。

省略主句

If I were at home now.

要是我现在在家里该多好啊。

If only I won the game

我要是赢了比赛多好啊!

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。

If I were you, I would go to look for him.

如果我是你,就会去找他。

If I were a bird, I would fly day and night.

如果我是一只鸟,我会没日没夜的飞翔。
