高中语法解析虚拟语气虚拟语气是语法中的一个重要概念，它用于表达与事实相反的假设、愿望、建议、命令等。
在高中英语学习中，学生们需要掌握虚拟语气的用法以及对应的句型结构。
本文将详细解析高中语法中的虚拟语气，并提供一些练习题来帮助学生巩固掌握。
一、虚拟语气的用法1. 表达与事实相反的假设虚拟语气常用于虚构的情况、与事实相反的假设，例如：- If I were rich, I would buy a big house.- If she had studied harder, she would have passed the exam.在这两个句子中，使用了虚拟语气来表达与现实情况相反的假设，即作者并不是富有的、她也没有努力学习。
2. 表达愿望当我们想表达自己的愿望、期望时，可以使用虚拟语气，例如：- I wish I could travel around the world.- I wish it would stop raining.这两个句子中，使用了虚拟语气来表达作者的愿望，他们希望能够环游世界、希望雨停。

二、虚拟语气的句型结构1. 谓语动词在虚拟语气中的形式变化在虚拟语气的句子中，谓语动词的形式会发生变化。
⾼中英语虚拟语⽓⽤法详解虚拟语⽓语⽓（mood）也是动词的⼀种形式变化。
这和中⽂中的语⽓是不⼀样的。
它表⽰说话者对所指的动词或状态所持的态度，⽽且，在谓语动词上有所体现，⽽中⽂没有体现。
语⽓可分为三种：陈述语⽓、祈使语⽓和虚拟语⽓。
虚拟语⽓（the Subjunctive Mood）表⽰说的话不是事实，或者是不可能发⽣的情况，⽽是⼀种愿望、建议或与事实相反的假设等。
⼀、虚拟条件句1．主句和从句都与现在事实相反时，从句⽤⼀般过去时，be的形式要⽤were，主句⽤would/could/ should/might+不定式⼀般式。
If I were you, I should not go with him.2．主句和从句都与过去事实相反时，从句⽤过去完成时，主句⽤would/should/could/might+不定式完成式。
If I had tried hard last term, I would have succeeded.3．当主句和从句都与将来事实相反，或指不⼤可能发⽣的事的时候，从句和与现在事实相反的从句时态相同，或⽤should/were to+不定式⼀般式，主句和与现在事实相反的主句相同。
If it rained/were to rain/should rain tomorrow, the match would be put off.4．在使⽤虚拟条件句时，由于语⾔环境的千差万别，各种时间关系混合使⽤是很常见的。
如果逻辑上讲得通，主句和从句的动词时态可进⾏各种各样的搭配。
If it hadn't rained those days, （从句与过去事实相反）1 work would be finished next week. （主句与将来事实相反）2.here wouldn't be any water in the river now. （主句与现在事实相反）⼀、语⽓及其种类1．语⽓（mood）语⽓是⼀种动词形式，表⽰讲话⼈对某⼀⾏为或事情的看法和态度。
高中英语虚拟语气的用法一、考查虚拟语气在条件从句中的用法时间从句谓语形式（be用were不可改变）主句谓语形式将来一般过去时(be用were) would/should/might/could+动词原形现在一般过去时(be用were) would/should/might/could+动词原形过去现在完成时would/should/might/could+had done（1）If he my advice, he wouldn' t have lost his job.A. followedB. should followC. had followedD. would follow（2）If we the other road, we might have arrived here in time for the meeting.A. takenB. had takenC. tookD. have taken（3） -John went to the hospital alone.-If he me about it, I would have gone with him.A. should tellB. tellsC. toldD. had told二、考查特殊句型中的虚拟语气英语中需要使用虚拟语气的特殊句型不多，主理有以下类:1.“倒装”类虚拟语气当虚拟条件句中含有were, should, had时,有时可将引导虚拟条件句的连词if省略,而将从句中的were,should, had提到句首,构成倒装形式的虚拟语气。
如:If he were here, she would agree too.→Were she here, she would agree too.如果她在这里,她也同意的。
.If it should rain tomorrow, we should have to put off the match. →Should it rain tomorrow, we should have to put off the match.假若明天下雨,我们只好推迟这场比赛。
If we had found him earlier we could have saved his life.→Had we found him earlier we could have saved his life. 要是我们当时早点找到他的话,我们就可以救活他。
注意,如果条件从句的谓语为否定式,其中的否定词not应置于主语之后,而不能与were,should, had等缩略成Weren' t, Shouldn' t, Hadn'场置于句首。
如:我如不是警告了你,你就可能丧命了。
正: If I hadn' t warned you, you could have been killed.正: Had I not warned you, you could have been killed.误: Hadn' t I warned you, you could have been killed.另外,有时省略if后提前到句首的had可能不是助动词,而是实义动词。
如: Had I time, I would go with you.假如我有时间,我就同你们一起去。
句中的had不是构成过去完成时的助动词,而是表示“有”,如果不省略if ,完整形式为:If I had time, I would go with you.(1) Had I known about this computer program, a huge amount of time and energy____.(2010浙江卷)A.would have been savedB. had been savedC. will be savedD. was saved（2） fired, your health care and other benefits will not be immediately cut off. (2006湖北）A. Would you beB. Should you beC. Could you beD. Might you be2.“宁愿”类虚拟语气这里说的“宁愿”主要是指would rather。
当它后接句子的时候,句子的谓语通常要用虚拟语气,其期法及结构形式为:若从句内容是涉及的是对现在或将来情况的希望,则从句谓语用一般过去时;若从句内容是涉及的是对过去已发生情况表示遗憾或后悔,则从句谓语用过去完成时。
如:I' d rather you went home now.我希望你现在就回家。
Tomorrow' S difficult. I' d rather yon came next weekend.明天有困难,我希望你下周末来。
I' d rather I had gone to the theatre last night.我倒希望我昨晚我去了剧院看戏。
（1）.George is going to talk about the geography of his country, but I' d rather he more on its culture.A. focusB. focusedC. would focusD. had focused4.“建议”类虚拟语气（suggest表建议的时候）但是,若suggest表示"暗示”"表明”“指出””提出(看法)”等,则从句谓语要用陈述语气。
如: His smile suggested that he was satisfied.他的微笑表明他是满意的。
（1）.Teachers recommend parents their children under 12 to ride bicycles to school for safety.A. not allowB. do not allowC. mustn' t allowD. couldn' t allow（2）.The workers will go on strike if the demands they_____ put forward are turned down.A. couldB. wouldC.不填D. had3. "坚持”类虚拟语气这类虚拟语气主要指动词insist后接宾语从句时所用的虚拟语气。
若从句内容是既成的事实,不容置疑,则从句谓语用陈述语气,此时insist的意思是”坚持说”; 若从句内容虽然还不是事实,但非常希望它成为事实,从句谓语用虚拟语气,即采用"should+ 动词原形”的形式,且其中的should在美国英语中可以省略,此时insist的意思是"坚持要”。
比较并体会: He insisted that I had read his letter.他坚持说我看过他的信。
He insisted that I should read his letter.他坚持要我看他的信。
He insisted that he was not il, but the doctor insisted that he should take the medicine.他坚持说他没有病,但医生却坚持要他服药。
4. “愿望”类虚拟语气这类虚拟语气主要指动词wish和固定搭配if only后所接从句使用的虚拟语气,但不包括动词hope在内。
此类虚拟语气的结构特点如下:从句主句现在情况一般过去时/过去进行式过去情况过去完成时/ would (could)+have +过去分词将来情况would (could, might) +动词原形I wish I could swim.我要是会游泳就好了。
I wish I had been here yesterday.我真希望我昨天在这里。
I wish he could come tomorrow.我希望他明天能来。
I wish you would come if you had time.你如有时间的话,我希望你来。
If only I knew her name!我要是知道她的名字就好了!If only you had let me know earlier.要是你早点让我知道就好了。
If only she would go with me!她要是愿意和我一道去就好了!5.“似乎”类虚拟语气这类虚拟语气主要指由表示“好像”和“似乎”的as if以及as though引出的虚拟语气句子。
既然是“好像”怎么样，或者是“似乎”怎么样,所以它描述的内容就不大可能是事实,或者说可能是非真实的,所以它的谓语通常要用虚拟语气,其结构形式与wish后从句的谓语形式差不多。
如: I' ve loved you as if you were my son.我爱你就像我的儿子。
He talks as if he had a potato in his mouth. 他讲起话来仿佛嘴里含了一个土豆似的。
She looked as if she had seen a ghost. 她看起来好像刚才遇见了鬼似的。
根据各句的句意可知，"你”显然不是“我”的儿子，所以第一句中as if从句的内容是非真实的,故用虚拟语气;“他”说话的时候嘴里肯定没有含一个土豆,所以第二句中as if 从句的内容也是非真实的，故也用虚拟语气;大家知道“鬼”是不存在的,所以她好像见到鬼的内容也是不真实的,所以第三句的as if从句也用虚拟语气。
但是,如果说话者认为as if 或as though从句所表示的内容是真实的,或者说是有可能成为事实的,那么也可以使用陈述语气。
如:We' ve missed the bus. It looks as if we' II have to walk.我们错过了公共汽车,看来我们得走路了。
6.“时候”类虚拟语气这类虚拟语气主要是指It’s time... (是做某事的时候了)后接从句时所使用的谓语形式--不管是针对现在还是将来的情况,一律使用-般过去时。
如:It' S time we ordered dinner.现在该叫菜了。
It' s time you washed those trousers. 你该洗洗那条裤子了。
I' m getting tired. It' s time we went home.我累了, 我们该回家了。
