虚拟语气讲解
虚拟语气讲解虚拟语气语气和时态、语态一样，是动词的一种形式，表明说话的目的和意图。
英语中有四种语气：陈述语气、疑问语气、祈使语气和虚拟语气。
陈述语气：表示谓语动词所表达的动作或状态是符合客观事实的，也就是把动作或者状态当做事实表达出来或者提出一种看法。
疑问语气：用来提出问题或询问情况的语气。
祈使语气：用来向对方提出请求、邀请，给予忠告、指示、警告、命令等的语气。
祈使句中的主语You一般省略，动词也用原型表示。
虚拟语气：把动作当做一种只存在于讲话人想象中的“假设”或“推测”，而不是当作客观事实中的真实事件。
它表达的通常是怀疑、忧虑、推测、想象或祝愿。
这里主要讲解虚拟语气的一般语法特征和难点。
一、虚拟语气在条件句中的用法条件句分为两种：一种是可能实现的，一种是无法实现的，可能实现的条件句叫真实条件句，不能实践的就是虚拟条件句。
1. 真实条件句：这种条件句实现的可能性非常大。
这类条件句常用if, unless, once, as long as等引导。
Eg. If you have any doubts about our plan, I’ll stop it. 如果你对我们的计划有怀疑，我会立刻终止它。
The secretary will get a pay raise as long as she does her job well. 这个秘书会得到加薪，只要她好好工作。
2. 虚拟条件句：往往指不能实现的或者纯假设的情况，可以对过去、现在或者将来的情况进行假象。
在这三种情况中，主句和从句中的动词也有不同的形式。
A. 与现在情况相反：表示对当前不可能实现的情况的假想，此时从句用一般过去式(did sth./ were...)，主句用过去将来式（would/ shoud/ could/ might do sth.）：Eg. If I were you, I would choose to work in a small town. 如果我是你，我会选择在小镇工作。
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。
虚拟语气语法讲解
虚拟语气语法讲解语法讲解--虚拟语气英语中有三种不同的语气：陈述语气，祈使语气和虚拟语气。
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。
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。
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。
If it should rain, the crops would be saved.If it were to snow tomorrow, they would not go out.P.S 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。
If you had followed my advice, you would be better now.(从句说的是过去，主句是现在)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。

英语虚拟语气讲解
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虚拟条件句的三种基本类型:1.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 you took a taxi，you’d get there quicker.如果你坐出租车去，你可以快一点到那里。
(但你不坐)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)2.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)If we had 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。
(可惜我们找到他太晚了)3.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 he went，would you go too? 如果他去，你也去吗?(大概他不会去)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)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。

注意！！！
如果条件从句是否定式，倒装时只能把 not 放在主语之后，不能用缩写式把not 放在主语之前。 e.g. Had you not told me about the matter, I should never have known the whole thing. (不能说：Hadn’t you told me…)
