(完整版)高中虚拟语气用法详解
一、什么是虚拟语气虚拟语气是一种动词形式,表示说话人的一种愿望,假设,怀疑,猜测,建议等含义,虚拟语气所表示的含义不是客观存在的事实。
If I were you, I'd take them away. 如果我是你的话,我就会带走他们。
(不可能是你,所以这是不存在的事实,所以用虚拟语气)If I had met Tom, I could have told him. 如果我碰见了Tom,我就告诉他了。
If I had time, I could come to help you. 如果我有时间,我会来帮助你的。
He suggested that our class should be divided into five groups. 他建议说我们的班应该分成五个小组。
He speaks to us as if he had been there. 他给我们讲的好像他去过那儿。
二、虚拟语气的用法虚拟语气在一般用于简单句,宾语从句,主语从句,表语从句,壮语从句以及同位于从句。
(下面我们分别看一下)1) 虚拟语气用在简单句中,表示祝愿,命令,它的谓语动词就是原形。
May you be happy. 祝你幸福。
May you have a good time. 祝愿你玩的痛快。
May the friendship between us last long. 祝愿我们的友情天长地久。
Have a good journey! 祝愿你旅途愉快!You go out!你出去!2) 虚拟语气用在宾语从句中。
在suggest, advise, propose, insist, demand, desire, request, require, decide, order, command等动词后的宾语从句中,要用虚拟语气,表示建议、要求、决定或命令等,其谓语动词形式为should+动词原形,其中should可以省略,主句中的时态不限。
2025届高考英语语法复习虚拟语气知识讲解讲义
高考英语语法复习虚拟语气知识讲解一、基础知识(一)什么是虚拟语气谓语动词的作用不仅可以表示动作的时间、状态、假设(情感),也是一种语气(mood)的表现形式,表明说话的目的和意图。
(语气包含陈述语气、祈使语气、虚拟语气、疑问语气)虚拟语气用于表示假设、愿望、建议、命令等非真实或虚拟的情况,即与真实相反。
上学的时候老师经常举的一个例子,"If I were you"因为我不可能是你,这是一种不可能存在的事实,所以这是个虚拟语句。
总而言之英语中的虚拟语气可以分为两大体系:一是表示与事实相反的,或者是假象的情形,通常由if引导,叫做虚拟条件句;另一个体系是在名词从句中使用虚拟语气,表示建议,命令或者要求等语气,类似于上述美剧常用的台词。
(二)虚拟语气的用法这一部分我们主要用虚拟语气在条件句中的用法作为讲解不同情况条件从句谓语主句谓语使用场景与过去事实相反If+主语+haddone主语+should/would/could/might+have done既然是过去了,那么谈到的一切情况都已既成事实,所以过去虚拟表达的是一个与过去事实相反的情形与现在事实相反If+主语+did(be动词用were)主语+should/would/could/might+do既可能是事实,也可能是假设条件。
因此,假设条件句和事实相反句适用于谈现在的情况与将来事实相反If+主语+ did(be动词用were)If+主语+ wereto + doIf+主语+should+ do主语+should/would/could/might+do对于将来时间的虚拟不可能以事实为基础,而只能是表达说话人的一个设想或愿望。
所以,对于将来的虚拟只适用于假设条件句,而不可能表达一个与事实相反的虚拟与现在事实相反:If I had a map, I would lend it to you.如果我有地图我就借给你。
(但我没有)与将来事实相反:If I were to do the job, I would do it in a different way. 要是我来做这工作,我会是另一种做法。
高中英语虚拟语气重点归纳
虚拟语气表示动作或状态与事实相反,或不可能发生的情况。
一.虚拟语气用于条件状语从句中1. 表示与现在事实相反或不可能发生:条件状语从句:一般过去时(虚拟语气中be→were)主句用:would(should, could, might)+动词原形。
Eg:If we had time now, we would read it again.If I were you, I would work hard.2. 表示与过去事实相反或不可能发生:条件状语从句:had+过去分词;主句:would(should, could, might)+have+过去分词。
Eg:If he had taken my advice, he would have succeeded in the test.If I had known your telephone number then, I would have called you.3. 表示与将来的事实可能相反或不可能发生:条件状语从句:①一般过去时②should +动词原形③were to+动词原形;主句:would(should, could, might)+动词原形。
Eg:If it should rain, the crops would be saved.If it were to snow tomorrow, they would not go out.注:虚拟条件句的特殊情况(1)混合/错综型虚拟语气当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,称为‘错综条件句’,动词的形式要根据它所表示的时间作出相应的调整。

高中英语虚拟语气详细讲解虚拟语气什么是虚拟语气?是的,我们要学习虚拟语气就必须先弄明白它的概念。
虚拟语气包含两种:一种指与事实相反或不可能发生。
“虚拟条件句+虚拟主句”的结构都属于这一类;even if、even though、as if、as though引导的状语中如果需要用到虚拟语气也属于这一类;wish、would rather后面接的宾语从句表示不可能实现的愿望,还是属于这一类。
另一种指与事实实际是否发生没有直接关系。
如和suggest、order、demand等表示建议、命令、要求等相关的名词性从句都属于这一类。
大家知道以上两类虚拟语气后,我们就从从句的角度来系统学习虚拟语气。
紧跟小简老师的步伐哦!一. 虚拟条件句中的虚拟语气1、表示与现在事实相反的情况从句:If+主语+did(be动词用were)主句:主语+ should/would/might/could+doIf I were you,I would take an umbrella.如果我是你,我会带把伞。
(事实:我不可能是你)If I knew his telephone number,I would tell you.如果我知道他的电话号码,我就会告诉你。
(事实:不知道)If there were no air or water,there would be no living things on the earth.如果没有水和空气,地球上就不会有生物。
(事实:地球上既有空气也有水)2、表示与过去事实相反的情况从句:If+主语+had+done主句:主语+should/would/might/could+have doneIf I had got there earlier,I should/would have met her. 如果我早到那儿,我就会见到她。
(事实:去晚了)If he had taken my advice,he would not have made such a mistake.如果他听我的劝告的话,就不会犯这样的错误了。
(事实:没有听我的话)3、表示与将来事实相反的情况从句:①if+主语+were to do②if+主语+should+do③if+主语+过去式(be动词用were)主句:主语+should/would/might/could+doIf 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:不可能来)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:不可能下雪)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:不可能来)注意事项:①错综时间句:即虚拟条件状语从句与虚拟主句中谓语动作的时间不一致。
If I had worked hard at school,I would be an engineer,too.如果我在学校学习刻苦的话,我现在也会成为一个工程师了。
If they had informed us,we would not come here now.如果他们通知过我们的话,我们现在就不会来这里了。
If he knew her,he would have greeted her that day.如果他认识她的话,他肯定会去问候她了。
②虚拟条件句中的省略:当虚拟条件句的谓语动词含有were,should,had 时,if 可以省略,这时条件从句要用倒装语序,即把were,should,had等词置于句首,这种多用于书面语。
Should he agree to go there,we would send him there.要是他答应去的话,我们就派他去了。
Were she here,she would agree with us.如果她在这儿的话,她会同意我们的。
Had he learnt about computers,we would have hired him to work here.如果他懂一些电脑知识的话,我们已经聘用他来这里工作了。
③用其它形式表达虚拟条件:虚拟条件状语从句有时不表达出来,只暗含在副词、介词短语、上下文或用其它方式表示出来。
如without…,but for…(要不是...)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。
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。
We didn't know his telephone number,otherwise we would have telephoned him.我们不知道他的电话号码,否则我们就会给他打电话。
④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。
⑤在虚拟条件句中,should/would/might/could四个词只能用should;在虚拟主句中,主语只有是第一人称时,才能用should。
If I had got there earlier,I should/would have met her.如果我早到那儿,我就会见到她。
If he had got there earlier, he would have met her.如果我早到那儿,我就会见到她。
二. 名词性从句中的虚拟语气1、表达和建议、要求、命令、主张等含义相关的名词性从句,一律用主语+should+动词原形(should可以省略)结构。

2、表示重要性、必要性、吃惊等时,一律用it is+形容词+that+主语+should+动词原形(should可以省略)结构。
例如:It's important that you (should) study English hard.努力学习英语是很重要的。
