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。

(完整word版)高中英语语法之虚拟语气讲解
【The Subjunctive Mood】语气(mood)是一种动词形式，用以表示说话者的意图或态度。
英语中的语气有三种：陈述语气、祈使语气和虚拟语气。
直陈语气(indicative mood),表示所说的话是事实。
祈使语气(imperative mood),表示所说的话是请求或命令。
虚拟语气(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. 虚拟语气在条件句中的应用学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。
真实条件句所表的假设是可能发生或实现的，句中的条件从句与结果主句都用陈述语气。
如：If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。
Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。
虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句与结果主句皆须用虚拟1. 与现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were), 主句的谓语用should （would, might，could）+动词原形。
如：If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。
（事实是：天在下雨，我们不能出去野餐。
表示愿望。
）If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。
（事实是：他没来这，他不可能帮助你。
表示对他的良好印象。
）2. 与过去事实相反的虚拟条件句，条件从句的谓语用had+过去分词，主句的谓语用should （would, might，could）+ have ＋过去分词。

虚拟语气在特定句型中应用
It is time that…句型
定义 It is time that…句型表示“现在是……的时候了”，其中 that从句中的谓语动词用过去时，有时也用“should+动 词原形”（较少见，且should不能省略）。
用法示例
It is time that we went to bed. 我们该睡觉了。或者 It is time that we should go to bed. 我们该睡觉了。
03
名词性从句中虚拟语气应用
宾语从句
wish后的宾语从句：表示与现在事实相反的愿望，从句用一般过去时；表示与过去事实相反 的愿望，从句用过去完成时；表示与将来事实相反的愿望，从句用could/would/might+动 词原形。
suggest, propose, recommend, demand, require, request, desire等动词后的宾语从句： 从句谓语由“should+动词原形”构成，其中的should在美国英语中通常可以省略。
虚拟语气在倒装句中应用
虚拟语气在倒装句中的应用主 要是指当虚拟条件句的谓语部 分含有were, had或should等词 时，可将这些词置于句首，采 用部分倒装的结构。
这种倒装结构在表达虚拟语气 时，可以使语气更加委婉、客 气或正式，常用于书面语中。
需要注意的是，在倒装结构中， 如果省略了if，则需要将were, had或should等词提至主语之 前，形成完全倒装的结构。同 时，主句中的语序和时态也需 要进行相应的调整。
和特殊用法的理解和运用还有待提高。
教师评语和建议
学生对虚拟语气的掌握情况良好
通过课堂表现和作业完成情况来看，学生对虚拟语气的掌握情况良好，能够正确运用虚拟语 气表达不同的意思。
高中英语虚拟语气知识点总结
高中英语虚拟语气知识点总结高中英语虚拟语气知识点总结虚拟语气是英语语法中一种用于描述假设、假想或可能性的语气。
在高中英语中，虚拟语气是一个相当重要的语法知识点。
本文将总结高中英语虚拟语气知识点，帮助学生更好地掌握虚拟语气的使用规则和技巧。
一、虚拟语气的定义及用途虚拟语气指的是表示假想、虚构、愿望、建议等情况的语气。
它强调实现的可能性很小或很远，或者根本就不可能实现。
虚拟语气通常使用“if”引导条件从句或用于表达思想、态度。
虚拟语气的用途主要有以下几个方面：1. 表示假想或虚构情况例如：If I were you, I would not do that.（如果我是你，我不会那么做。
）2. 表示可能性很小或很远例如：If you asked him, he might help you.（如果你问他，他可能会帮你。
）3. 表示愿望、要求或建议例如：I wish I could speak fluent English.（我希望我能说流利的英语。
）二、虚拟语气的形式虚拟语气形式主要有以下几种：1. 虚拟语气的过去式：在虚拟语气中，一般用过去式来表示对现在或未来的虚拟。
例如：If I had more time, I would read more books.（如果我有更多时间，我就会多看书。
）2. 虚拟语气的过去完成式：过去完成式用于表示“如果过去已经发生了某些事情，结果会是怎样”。
例如：If I had studied harder in high school, I would have gone to a better college.（如果我在高中时学习更努力，我就能进入更好的大学。
）3. 虚拟语气的“would + 动词原形”形式：“would +动词原形”形式通常用于表示愿望、要求、建议或者可能性。
例如：I wish you would stop smoking.（我希望你戒烟。
）If you would like to come, you are welcome.（如果你愿意来，欢迎你。
人教版高二英语必修六语法点の虚拟语气
人教版高二英语必修六语法点の虚拟语气人教版高二英语必修六语法点の虚拟语气虚拟语气表示一种不能实现的假设。
该语法主要用于if条件状语从句。
一、if引导的条件状语从句的分类及虚拟条件句的判断1、可以把条件句分为两类：1).真实条件句：凡是假设的情况发生性可能很大，就是真实条件句。
例如：(1)、If I have time, I will help you with this work.如果我有时间会帮助你做此工作的。
(2)、If time permits, we’ll go fishing together. (如果有时间的话，我们就一起去钓鱼。
）2).虚拟条件句：当假设是不大可能实现时，就是虚拟条件句。
例如：⑴、If I were you, I would have attended the meeting.如果我是你的话，就去参加会议了。
⑵、If he had come here yesterday, he would have seen his old friend.假如他昨天来这儿的话，就会看见他的老朋友。
(3)、If it had rained yesterday, we would have stayed at home.（如果昨天下雨的话，我们就会留在家里。
）2、if条件状语从句中虚拟语气的判断判断是真实条件句还是非真实条件句。
只有在非真实条件句中才使用虚拟语气。
通过句子意思，看假设的条件是否能够实现，能够实现是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用虚拟语气。
判断这个假设是与哪个事实相反。
通常有三种情况：①与过去事实相反。
②与现在事实相反。
③与将来事实可能相反。
3、“后退一步法”后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从句谓语动词的时态。
即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。
也就是：①与过去事实相反，在从句中用过去完成时形式表示。
