虚拟语气虚拟语气(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形式，用来表示说话人所说的话并非是事实，而是一种假设、愿望、疑心或推测。
Ⅰ用以表示虚拟条件的虚拟语气虚拟条件句的三种大体类型:1.与此刻事实相反。
假设与此刻事实相反，条件从句的谓语用过去式(be通经常使用were)，主句谓语用“should (would, could, might)+动词原形”：If you took a taxi，you’d get there quicker. 若是你坐出租车去，你能够快一点到那里。
(但你不坐)If I knew her number I could ring her up. 若是我明白她的号码，我就能够够给她打了。
(可惜我不明白)2.与过去事实相反。
假设与过去事实相反，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.若是我早点起身，我就准时到了。
(但我起身太迟了)If we had found him earlier we could have saved his life. 若是咱们那时早点找到他的话，咱们就能够够救活他。
(可惜咱们找到他太晚了)3.与以后事实相反。
假设与以后事实相反，条件从句的谓语用过去式(be通经常使用were)，主句谓语用“should (would, could, might)+动词原形”：If he went，would you go too? 若是他去，你也去吗?(可能他可不能去) If I asked him，I’m sure he’d help us. 若是我向他提出要求，确信他会帮忙咱们。
(只是我不打算如此做)大多数的虚拟条件句属于上面三种情形的一种，但并非排除存在条件和后果中，一个和此刻情形相反，另一个和过去情形相反，例如：If you had followed what the doctor said, you would not have been so painful now.那个句子在高中显现频率颇高。

在本文中，将对虚拟语气的几个主要知识点进行归纳总结。
1. 条件句中的虚拟语气在条件句中，虚拟语气通常用于表示与当前事实相反的情况。

虚拟语气语法总结虚拟语气是一种在句子中表示假设、愿望、推测、建议、命令等语气的语法结构。
它在很多语言中都存在，在英语中尤为常见。
虚拟语气有时可以用来表示与实际情况相反的假设，有时则用来表示无法实现的愿望或推测。
在英语中，虚拟语气分为三种形式：过去虚拟语气、现在虚拟语气和将来虚拟语气。
在本篇总结中，我们将详细介绍这三种虚拟语气的用法和结构。
一、过去虚拟语气过去虚拟语气用来表示与现实情况相反或与过去事实不符的假设。
它的主要结构是“had + 过去分词”，常用于if条件从句或wish从句中。
1. 用于if条件从句：如果我有时间，我就会去看电影。
If I had time, I would go to see a movie.假如你帮我，我就会更快地完成工作。
If you helped me, I would finish the work faster.2. 用于wish从句：我希望你住得近一点，这样我们就可以经常见面了。
I wish you lived closer so that we could see each other more often. 她希望她昨晚去了宴会。
She wishes she had gone to the party last night.二、现在虚拟语气现在虚拟语气用来表示与现实情况相反或不太可能实现的愿望、建议、要求等。
它的主要结构是“should + 动词原形”或“were + to + 动词原形”。
1. 用于虚拟的愿望：如果我是你，我会马上辞职。
If I were you, I would quit my job immediately.（“were”表示与现实情况相反的假设）我希望你明白我的意思。
I wish you understood what I mean.（“understood”表示与现实情况不符的愿望）2. 用于虚拟的建议和要求：你应该尽早去看医生。
英语虚拟语气的三种时态三种时态中的英语虚拟语气虚拟语气（Subjunctive Mood）是英语语法中的一种特殊形式，用来表达与事实相反、与现实不符合或带有假设、建议、命令等语气的情况。
在英语中，虚拟语气可用于过去、现在和将来三种时态。
本文将详细介绍英语虚拟语气在这三种时态中的应用。
一、过去式虚拟语气（Past Subjunctive）过去式虚拟语气用于对过去发生的事情进行虚拟表达。
它通常与“if”或“wish”等引导的从句连用，表示对过去事实的非真实假设或对过去的遗憾、愿望等。
用法如下：1. 与现在事实相反的假设：If I were you, I would apologize.（如果我是你，我会道歉。
）If she had studied harder, she would have passed the exam.（如果她学得更努力，她就能通过考试。
）2. 对过去的遗憾、愿望：I wish I had taken that job.（我希望我当时接受了那份工作。
）He wishes he were taller.（他希望自己更高一些。
）二、现在式虚拟语气（Present Subjunctive）现在式虚拟语气用于对现在或将来的事情进行虚拟表达。
它通常与“if”或“suggest”等引导的从句连用，表示对现实的非真实假设、建议或要求。
用法如下：1. 对现在事实相反的假设：If it were to rain, we would stay at home.（如果下雨的话，我们将呆在家里。
）I suggest that he be more careful.（我建议他更加小心。
）2. 对现在的建议或要求：It is important that she arrive on time.（她准时到达是很重要的。
） They demanded that he pay the bill immediately.（他们要求他立即支付账单。
虚拟语气虚拟语气表示说话人的主观愿望、猜测、建议或与事实不符的假设等，也可以表示可能性较小的情况或不可能发生的情况，而不是客观存在的事实(表示客观事实要用陈述语气)。
虚拟语气是由句中谓语动词的特殊形式表现出来的。
虚拟语气常用于复合句中，也可用于简单句。
比较：If she asks me tomorrow,I shall do it.如果她明天请求我，我会做的。
(陈述语气，说话人认为请求的可能性大)If she asked me tomorrow, I should do it. 假如她明天请求我，我会做的。
(虚拟语气，说话人认为请求的可能性小或不可能请求)1 虚拟语气的用法1-1 虚拟语气用于条件状语从句中1)表示与现在事实相反的情况If I were/was not busy today, I should go with you.如果我今天有空，我会同你一起去的。
If he were/was here,he might talk with you.如果他在这里，他可能会同你谈谈。
If I were you,I wouldn't accept her suggestion.如果我是你，我不会接受她的建议。
If I knew the answer to the question,I should/ would tell you.如果我知道问题的答案，我当然会告诉你。
If we left now, we should/would arrive there in time.如果我们现在就动身，我们会准时到达那里。
If he didn't do exercise every day,he wouldn't be so strong.如果他不每天锻炼，他不会那样强壮的。
If it weren't raining, we would go fishing.要是现在不下雨，我们就去钓鱼了。
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。
