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。
虚拟语气用法总结及详细解析
虚拟语气用法英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。
1、表示动作或状态是客观存在的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句中。
China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句)2、祈使句表示说话人对对方的请求、警告，建议或命令。
如:Please come over here. 请到这边来。
Watch your steps! 当心!(走路)3、虚拟语气表示说话者做出的假设而非事实，或难以实现的情况，甚至表达彻底相反的概念。
此外，如需表达主观愿望或某种强烈的感情时，也可用虚拟语气。
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。
If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。
If she were to be here next Monday, I would tell her about the matter.如果她下周一来这儿的话，我就会告诉她这件事的始末。
4、有时，虚拟条件句中，结果主句和条件从句的谓语动作若不是同时发生时，虚拟语气的形式应作相应的调整。
这种条件句叫错综条件句。
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。
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，我现在也会成为一个工程师了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。

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。

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。

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。
高中英语语法-虚拟语气全总结
高中英语语法-虚拟语气全总结虚拟语气用于表示与现实相反的假设。
在非真实条件句中，如果从句表示与现在事实相反的假设，主句应该使用XXX动词原形。
例如，如果我有时间，我会参加会议。
如果你是我，你会抓住出国的机会。
如果从句表示与过去事实相反的假设，主句应该使用主语+XXX过去分词。
例如，如果你听从了我的建议，你就不会在考试中失败了。
如果从句表示与将来事实相反的假设，主句应该使用主语+XXX动词原形。
例如，如果你明天来，我们就会开会。
如果明天下雨，我们就会推迟运动会。
如果他明天不来，我们就会推迟会议到下周一。
有时候，条件状语从句和主句所表示的时间不一致，这时候被称为错综时间条件句。
动词的形式要根据它所表示的时间作出相应的调整。
例如，如果你刚才听从了我的建议，你现在会更好。
如果你之前努力研究，你现在就是一名大学生了。
在条件句中，可以省略if，把were、had、should提到句首，变成倒装句式。
例如，如果我还有上学的机会，我会更加努力研究。
→Were I at school again。
I would study harder.Had you arrived earlier。
you would have caught the bus.If it rains tomorrow。
we won't be able to go climbing.What would you do if you had a n dollars?Without your help。
we XXX the work ahead of time.I was ill that day。
otherwise I XXX.He called me to inform me about your birthday。
or else I wouldn't have known about it.A man who s drinking water would be dead in about seven days.I might have been able to offer you more assistance。

虚拟语气归纳总结
虚拟语气在主语从句、宾语从句等中运用
主语从句中虚拟语气的使用
当主语从句表达与事实相反的情况时，谓语动词用虚拟语气，其形式通常为“should + 动词原 形”或只用动词原形（美国英语）。
宾语从句中虚拟语气的使用
当宾语从句表达与事实相反的情况时，谓语动词也用虚拟语气，其形式与主语从句相同。
表语从句和同位语从句中虚拟语气的使用
忽略从句类型
定语从句分为限制性和非限制性两种，不同类型的从句在 使用虚拟语气时有所不同。如果在应该使用虚拟语气的从 句中忽略了这一点，就会导致语法错误。如：“The plan, which I suggest, should be carried out immediately.” （我建议的计划应该立即执行。）这个句子中，非限制性 定语从句“which I suggest”没有使用虚拟语气，因此是 错误的。正确的表达应该是：“The plan, which I suggest should be carried out immediately, is very important.”（我建议应该立即执行的计划非常重要。）
典型错误分析
误用虚拟语气
在非正式场合或口语中，有时会用虚拟语气表达强烈的愿 望或假设，但在正式书面语中，需要根据语境恰当使用。 如：“I wish I was a millionaire.”（我希望我是个百万 富翁。）这种表达在口语中常见，但在正式书面语中应改 为：“I wish I were a millionaire.”
