高中英语之虚拟语气详细讲解
虚拟语气（1）——倒推时态类定义：虚拟语气是一种动词形式，有两种意思 1.表示说话人所说的不是事实，而是一种假设、猜测、怀疑等（非真实条件状从和让步状从）2.表示说话人的愿望、要求、命令、建议（名词性从句：主宾表同）使用情景 1.用来表达一个假设或纯粹的意愿（与事实相反或不太可能实现）（如果我是宇航员，我要在月球上跳舞）2.用来缓和语气，使句子更委婉、礼貌、得体（如果你能接受我的邀请，我将不胜感激）3.表示烦恼、不耐烦等情绪（你要是能考上大学，全家都烧高香了）4.表示适度的责备或批评（如果你那时更耐心点，现在我们都成功了）5.表示美好的祝愿或祝福（祝你成功）1.虚拟条件句一般虚拟条件句混合虚拟语气（错综时间条件句）定义：条件状语从句表示的行为和主句表示的行为发生的时间不一致例子：If you had followed my advice, you would be better now.如果那时你听了我的建议，现在已经好了If it hadn’t been for you, I would have to make another trip there tomorrow.如果不是你的话，我明天还要再走一趟。
If you had studied hard before,you would be a college student now.如果你以前努力学习的话，你现在就是大学生了。
省略+倒装当虚拟条件句的谓语动词中含有were，should，had时，if可以省略，并将were,should,had提前于句首，变为倒装句。
如果虚拟条件句是否定句，not 保留在原处If he should agree to go there, we should send him there.= Should he agree to go there,we should send him there.If she were there,she would agree with us.= Were she were, she would agree with us.If he had learnt about computers,we would have hired him.= Had he learnt about computers,we would have hired him.含蓄虚拟条件句定义：有时为了表达的需要，在虚拟语气中并不总是出现if引导的条件状语从句，而是通过其他手段来代替条件从句分类：1) but for....=(If it+be not for) ；without；Without your help ,we couldn’t have finished the work ahead of time.= But for your help,we couldn’t have finished the work ahead of time.= If it hadn’t been for your help,we couldn’t have finished the work ahead of time.没有你的帮助，我们不可能完成任务。

英语语法—虚拟语气(最全)
虚拟语气1.虚拟语气的概念虚拟语气把动作当作一种只存在于讲话人想象中的“假设”或“推测”，而不是当作客观现实中的真实事件。
它表达的是建议、不满、怀疑、忧虑、推测、假设、想象、祝愿等。
2.虚拟语气用于非真实条件句英语中的条件句有两种：真实条件句和非真实条件句。
真实条件句实现的可能性非常大，常用if, unless, as long as, so long as, once等引导，谓语动词常用陈述语气；非真实条件句常表示不能实现或纯假象的情况，谓语动词要用虚拟语气。
非真实条件句包括虚拟条件句、推测条件句、错综时间条件句。
①虚拟条件句、推测条件句虚拟条件句可分为两类：一类是叙述与现在事实相反的情况，一类是叙述与过去事实相反的情况。
另外，还有一类用于推测将来的情况，也称作推测条件句。
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，主句会产生一种不可能获得的结果。
句中的虚拟语气根据不同的时间有3种不同的形式：I would lend him the money if he asked me.他要是问我，我愿意借钱给他。
(意愿)If he had time, he should do it.要是有时间，他愿意做那件事。
(意愿)He could move the big stone if he should try.努力的话，他能搬动那块大石头。
(能力)If he forgot to come, you could go instead.他要是忘了没来，你可要替他来。
(许诺)A.与现在事实相反If I had enough money, I would buy a computer.如果我有足够的钱，我将买一台电脑。
(实际上没有) Were I you I would refuse.如果我是你我会拒绝。
(我不是你)注：从句有时可用If it were not for这种句型，表示“若不是……”。
It it weren’t for your help, we would be in serious trouble.若不是你帮忙，我们会遇到大麻烦。

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。
Eg:If you had followed my advice, you would be better now.(从句说的是过去，主句是现在)Eg:If I were you, I would have taken his advice.(从句是现在，主句是过去)(2)省略if的虚拟语气如果从句中含有were/ should/ had时，则可以把这三个词置于句首，省略if.采用倒装语序。

If you had asked him yesterday, you would know what to do now.（从句与过去事实相反，主句与现在事实相反。
）If it had rained last night (过去), it would be very cold today (现在).虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should 或had 移到从句句首，实行倒装。
Were they here now, they could help us.=If they were here now, they could help us.Had you come earlier, you would have met him=If you had come earlier, you would have met him.Should it rain, the crops would be saved.=Were it to rain, the crops would be saved.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，即在从句中be用were代替。
If I were you, I would go to look for him.如果我是你，就会去找他。
If he were here, everything would be all right.如果他在这儿，一切都会好的。
典型例题_____ to do the work, I should do it some other day.A. If were IB. I wereC. Were ID. Was I答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成were, should, had +主语的形式。
但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。
如我们可说Were I not to do., 而不能说Weren't I to do.特殊的虚拟语气词：should1）It is demanded / necessar y / a pity + that…结构中的主语从句的谓语动词要用should 加动词原形，should 可省略。
句型：(1)suggestedIt is(2)importantthat…+ (should) do(3) a pity(1)suggested, ordered, proposed, required,demanded, requested, insisted；+ (should) do(2)important, necessary, natural, strangea pity,a shame,no wonder(3)It is suggested that we (should) hold a meeting next week.It is necessary that he (should) come to our meeting tomorrow.2）在宾语从句中的应用在表示命令、建议、要求等一类动词后面的从句中。
order, suggest, propose, require, demand, request, insist, command, insist + (should) doI suggest that we (should) hold a meeting next week.He insisted that he (should ) be sent there.注意：如suggest, insist不表示"建议" 或"坚持要某人做某事时"，即它们用于其本意"暗示、表明"、"坚持认为"时，宾语从句用陈述语气。
The guard at gate insisted that everybody obey the rules.判断改错:（错）You pale face suggests that you (should) be ill.(对)Your pale face suggests that you are ill.(错)I insisted that you ( should) be wrong.(对)I insisted that you were wrong.3）在表语从句，同位语从句中的应用在suggestion, proposal, idea, plan, order, advice等名词后面的表语从句、同位语从句中要用虚拟语气，即（should）+动词原形。
My idea is that we (should) get more people to attend the conference.I make a proposal that we (should) hold a meeting next week.wish的用法1）用于wish后面的从句，表示与事实相反的情况，或表示将来不太可能实现的愿望。
其宾语从句的动词形式为：真实状况wish后现在时过去时从句动作先于主句动词动作（be的过去式为were）过去时过去完成时从句动作与主句动作同时发生（had + 过去分词）将来不大可能实现的愿望将来时would/could +动词原形I wish I were as tall as you.我希望和你一样高。
He wished he hadn't said that. 他希望他没讲那样的话。
I wish it would rain tomorrow. 我希望明天下雨就好了。
2）Wish to do表达法。
Wish sb / sth to doI wish to see the manager. = I want to see the manager.I wish the manager to be informed at once. (= I want the manager to be informed at once.)比较if only与only ifonly if表示"只有"；if only则表示"如果……就好了"。
If only也可用于陈述语气。
I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。
If only the alarm clock had rung.当时闹钟响了，就好了。
If only he comes early.但愿他早点回来。
It is (high) time thatIt is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形，但should 不可省略。
