英语虚拟语气？虚拟语气英语，回答如下：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事实，而是一种假设、愿望、怀疑、建议、猜测、可能或纯粹的空想等，通常由 if 引导的状语从句与主句构成。五种基本句型：1、那么，英语虚拟语气？一起来了解一下吧。
英语虚拟语气指什么?
虚拟语气是说话者用来表示一种假想，或者难以达到的情形，而非客观存在的事实。
与现在的事实相反：条件从句If+主语+过去式（从句中系动词be多用were形式）；主句中主语+would或should+动词原形或+could.
与过去的事实相反：If+主语+had+过去分词；主句+would或should+have+过去分词或could.
与将来的事实相反：If+主语+过去式或should+动词原形或were+to+动词原形；主句中主语+would或should+动词原形或could.
条件句中虚拟语气的形式
从句中提出一种与客观现实不相符或根本不可能存在的条件,主句会产生的一种不可能获得的结果.条件句中的虚拟语气根据不同的时间有三种不同的形式.
时间 从句谓语形式 主句谓语形式
将来 动词过去式(be用were)
should + 动词原形
were to + 动词原形
would / should / might / could + 动词原形
现在 动词过去式(be 用 were) would / should / might / could + 动词原形
过去 had +动词过去分词 would / should / might / could have + 动词过去分词
2.条件中的虚拟语气的举例
(1) 将来时的条件句中的虚拟语气.如：
If he should go to Qing Hua University,he would make full use of his time.如果他要上清华大学的话,他就会充分利用他的时间了.
If he were to come here,he would tell us about it.如果他要来的话,他会通知我们一声.
(2) 现在时的条件句中的虚拟语气.如：
If he were free,he would help us.要是他有空的话,它会帮助我们的.
If he studied at this school,he would know you well.如果他在这所学校学习的话,它会对你很熟悉.
(3) 过去时的条件句中的虚拟语气.如：
If I had seen the film,I would have told you about it.我如果看过这场电影,我会把电影内容告诉你了.
If I had got there earlier,I would have met Mr.Li.如果我早点到那儿,我就会会到了李先生.
3.运用条件句中的虚拟语气时,须注意的几个问题
(1) 当从句的主语为第三人称单数时,谓语动词若是系动词be时,可用was代替were.但在倒装虚拟结构及if I were you,as it were中,只能用were.如：
Were I ten years younger,I would study abroad.要是我还年轻十岁的话,我会去国外学习.
If I were you,I would try my best to grasp the chance.要是我是你的话,我要尽力抓住这次机会.
(2) 有时,虚拟条件句中,主、从句的动作若不是同时发生时,须区别对待.
①从句的动作与过去事实相反,而主句的动作与现在或现在正在发生的事实不符.如：
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,我现在也会使工程师了
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.
②从句的动作与现在事实相反,而主句的动作与过去事实不符.如：
If he were free today,we would have sent him to Beijing.如果他今天有空的话,我们会已经派他去北京了.
If he knew her,he would have greeted her.要是他认识她的话,他肯定会去问候她了.
③从句的动作与过去发生的情况相反,而主句的动作与现在正在发生的情况相反.如：
If it had not been raining too much,the crops would be growing much better.如果天不下太多的雨的话,庄家会长得更好.
If he had been working hard,he would be working in the office now.要是他工作一直努力的话,他现在已进了办公室了.
(3) 当虚拟条件句的谓语动词含有were,should,had时,if可省略,而将were,should,had等词置于句首.如：
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.
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.如果她懂一些电脑知识的话,我们会已经聘用他来这里工作了.
(4) 有时,句子没有直接给出假设情况的条件,而须通过上下文或其他方式来判断.如：
I would have come to see you,but I was too busy.我本该来看你了,然而我太忙了.
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.
(5) 有时,虚拟条件句中,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.
①省略从句
He would have finished it.他本该完成了.
You could have passed this exam.你应该会通过这次考试了.
②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 had got it.要是我得到它了该多好啊.
、虚拟条件句的三种基本类型：与现在事实相反、与过去事实相反、与将来事实相反.
条件句有真实条件句和非真实(虚拟)条件句两种.真实条件句所表示的假设是有可能发生的,而非真实条件句则通常表示一种假想,与事实相反或不大可能会发生：
If I have time, I will go with them. 假若我有时间,我就同他们去.(陈述语气)
If I were you, I would go with them. 假若我是你,我就同他们去.(虚拟语气)
▲ 与现在事实相反
若与现在事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形”：
If I knew her number ,I could ring her up. 要是我知道她的电话号码,我就可以给她打电话了.(可惜我不知道)
▲与过去事实相反
若与过去事实相反,条件从句的谓语用过去完成时(had+过去分词),主句谓语用“should (would, could, might)+have+过去分词”：
If I’d left sooner,I’d have been on time. 要是我早点动身,我就准时到了.(但我动身太迟了)
▲与将来事实相反
若与将来事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形”：
If I asked him,I’m sure he’d help us. 如果我向他提出要求,肯定他会帮助我们.(不过我不打算这样做)
注：几点特别说明
① 主句谓语中的should主要用于第一人称后.would, might, could的大致区别是：would表示结果,might表示可能性,could表示能力、允许或可能性.比较：
If you tried again ,you would succeed. 要是你再试一试,你就会成功的.(would表结果)
If you tried again, you might succeed. 要是你再试一试,你可能会成功的.(might表可能)
If you tried again ,you could succeed. 要是你再试一试,你就能成功了.(could表能力)
④ 对于与将来事实相反的情形,请注意以下几点：一是这里说的与将来事实相反,实为对将来情况的推测；二是此用法中的条件从句谓语除用过去式外,有时也用“should+动词原形”(表示可能性极小,常译为“万一”)或“were to+动词原形”(表示与将来事实相反的假设)；三是当条件从句使用“should+动词原形”这样的谓语时,主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气外,也可用直陈语气或祈使语气：
If it should rain tomorrow, don’t expect me. 万一明天下雨,就不要等我了.（祈使语气）
If I should see him, I’ll tell him. 万一我见到他,我就告诉他.（直陈语气）
2、错综时间虚拟条件句
所谓错综时间虚拟条件句即条件从句与主句所指时间不一致,如从句指过去,而主句即指的是现在或将来,此时应根据具体的语境情况,结合上面提到的三种基本类型对时态作相应的调整：
If it had rained last night, the ground would be wet now. 要是昨晚下过雨的话,现在地面就会是湿的.
You would be much better now if you had taken my advice. 假若你当时听我的话,你现在就会好多了.
3、两个常考虚拟语气句型
▲ 句型介绍
这两个句型是If it weren’t for…和If it hadn’t been for…,这是两个很常用的虚拟语气句型,也经常受到命题人的青睐,其意为“若不是(有)”“要不是有”.如：
If it weren’t for water, no plant could grow. 要是没有水植物就无法生长.
If it hadn’t been for your assistance ,we wouldn’t have succeeded.
=But for your assistance ,we wouldn’t have succeeded.
=Without your assistance ,we wouldn’t have succeeded.
5、wish后宾语从句用虚拟语气
▲ 用法说明
动词wish后接宾语从句时,从句谓语要用虚拟语气.若要表示与现在事实相反的愿望,从句谓语用一般过去时或过去进行时；若表示与过去相反的愿望,从句谓语用过去完成时或would / could+have +过去分词；若表示将来没有把握或不太可能实现的愿望,用would (could)＋动词原形.如：
注：特别注意
从句的时态只与从句所指的时间有关,而与wish的时态无关,比较：
I wish I were rich. 要是我现在有钱就好了.
I wish I had been rich. 要是那时我有钱就好了.
I wished I were rich. 当时我后悔自己没有钱.
I wished I had been rich. 当时我后悔自己曾经没有钱.
6、if only后的句子用虚拟语气
if only 与 I wish一样,也用于表示与事实相反的愿望,其后所虚拟语气的时态与 wish后所接时态的情况相同：
If only she had had more courage! 她再勇敢一些就好了.
If only I had listened to my parents! 我要是当时听了父母的话就好了.
If only she would go with me! 她要是愿意和我一道去就好了!
注：if only 通常独立使用,没有主句.
7、as if (though) 从句用虚拟语气
▲ 基本用法
以as if (as though)引导的方式状语从句或表语从句,有时用虚拟语气,若表示与现在事实相反,谓语动词用一般过去时；若表示与过去事实相反,用过去完成时；表示将来的可能性不大,用would (might, could)+动词原形：
He acts as if he knew me. 他显得认识我似的.
They treat me as though I were a stranger. 他们待我如陌生人.
He talks as if he had been abroad. 他说起话来好像曾经出过国.
注：两点说明
(1) 从句所表示的内容若为事实或可能为事实,也可用陈述语气：
It looks as if we’ll be late. 我们似乎要迟到了.
(2) 注意 It isn’t as if…的翻译：
It isn’t as if he were poor. 他不像穷的样子(或他又不穷).
8、It’s time后的从句用虚拟语气
▲ 基本用法
从句谓语通常用过去式表示现在或将来,有时也用过去进行时或“should+动词原形”(较少见,且should不能省略),其意为“(早)该干某事了”：
It’s time we went [were going, should go]. 我们该走了.
It’s time I was in bed. 我该上床睡了.(不用were)
9、would rather后句子用虚拟语气
在would rather, would sooner, would just as soon 后的that从句中, 句子谓语习惯上要用虚拟语气, 表示”宁愿做什么” ,具体用法为：
▲ 一般过去时表示现在或将来的愿望

10、宾语从句用虚拟语气的10种类型

require, insist, urge, request, order, +that…(should )+动词原形
devide, ask, move, propose等
注意：在此结构中that不可省略；should省不省均可.
He suggested that they (should ) stop smoking.
上述动词的名词形式出现时,that 引导的从句仍用虚拟语气.
He made a request that they (should ) stop smoking.
如果that 引导的从句所表达的内容是事实,也可用陈述语气.
He insists that he is right.

I wish I had never stopped teaching. (=I am sorry I stopped teaching.)
I wish they’d let us get some sleep.
注意：wish与hope接宾语从句的区别在于：hope表示一般可以实现的希望,宾语从句用陈述语气.wish表示很难或不大可能实现的希望,宾语从句用虚拟语气.试比较：
（1） We hope they will come,(We don’t know if they can come.)
（2） We wish they could come,(We know they are not coming.)
4、as if, as though, would(had) rather(that)引导的从句须用虚拟语气,如：
He acts as if nothing had happened.
I would rather you didn’t tell him.

It’s high time (that) we took some action.
【导读】很多人对于公共英语三级考试望而怯步，认为自己基础不好，考试每年通过率又不高，所以认为考试难度很大，其实，决定考试通过率的因素有很多，很可能是考生没有复习好，又或者是临时弃考等等，所以不要先入为主的认为公共英语三级考试难度很大。为了帮助大家都能顺利通过考试，下面是小编为大家整理的“公共英语考试易考语法考点：虚拟语气”相关内容，希望对大家有所帮助。
虚拟语气表示说话人的主观愿望、猜疑、建议或与事实不符的假设等，而不表示客观存在的事实。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如：
If I were a bird，I would be able to fly in the air.如果我是一只小鸟，我就能在空中飞行。
I wish I could pass the examination.我希望我能通过考试。
1、普通型虚拟语气主句与从句动词虚拟形式的搭配如下：
与现在事实相反：从句为过去式(be一般were)，主句为would/should+动词原形;
例：If he studied harder，he might pass the exam(如果他努力学习，他可能通过考试了)
不论主语为第几人称，if从句中的be动词均用were;主句中的助动词一定为过去时，且后面接动词原形
例1：If I were you ，I would beat him
例2：If he were here，I would beat him
与将来事实相反：从句为should+动词原形，主句为wonld/should+动词原形;
例：If it should rain，the game would be put off(如果下雨，比赛会推迟)
使用要点：if从句一定要加助动词should，if……should翻译为“万一”;
与过去事实相反：从句为had+过去分词，主句为would/should+have+过去分词。
虚拟语气是英语语法考试中的重点，那么你掌握了吗?下面是我为你整理的英语虚拟语气的语法的相关资料，希望大家喜欢!
英语虚拟语气的语法归纳
虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一。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并不是事实，而是一种假设、愿望、怀疑或推测。
Ⅰ用以表示虚拟条件的虚拟语气
⒈ 用if条件从句表示的虚拟条件，是虚拟条件最普通的方式。
① 虚拟现在时表示与现在事实相反的假设，其if 从句的谓语形式用动词的过去式(be 一般用were)，主句用would/ should/ could/ might +动词原形，例如：If I were in your position I would marry her.
② 虚拟过去时是表示与过去事实相反的假设，if 从句的谓语形式用过去完成时即had+过去分词，主句用would / should / could / might + have +过去分词，例如：If it had not rained so hard yesterday we could have played tennis.
③ 大多数的虚拟条件句属于上面三种情况的一种，但并不排除存在条件和后果中，一个和现在情况相反，另一个和过去情况相反，例如：If you had followed what the doctor said, you would not have been so painful now.这个句子在高中出现频率颇高。
以上就是英语虚拟语气的全部内容，英语虚拟语气的用法有条件句、目的句、宾语句等。1、条件句。If he doesn't hurry up，he will miss the bus.如果他不快点，他将错过巴士。（真实）。If he is free。
