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。

（完整版）虚拟语气详解
（完整版）虚拟语⽓详解虚拟语⽓详解虚拟语⽓表⽰说话⼈的主观愿望（往往与客观事实相反），或是表⽰假象和猜测。
虚拟语⽓⽆论从形式上还是时态上都⽐较复杂，需要归类记忆。
虚拟语⽓⼤体分为三类：(1) be型虚拟(2) were型虚拟(3) if 条件句及主句虚拟下⾯会详细说每种虚拟形式的特征和规律，考试时先判断属于哪种虚拟类型，剩下的皆是套路~（1）be型虚拟（基本是套路）形式：should + 动词原形，should可以省略⽤法：1）表⽰“命令、建议、要求”等意义词语之后的宾语从句⽤be型虚拟，常见的词如下: demand, desire, insist, order, ask, command, propose, recommend, suggest, prefer, require, request等最常见的形式是这类动词后⾯接着⼀个宾语从句，则宾语从句的谓语部分要⽤（should）+ 动词原形来虚拟例: We demand that the meeting（should）be postponed.The manager suggested that we (should) work together.注意：有时候你所见到不⼀定是上述动词引导的宾语从句，⽽是由上述词变体后所引导主语从句(it做形式主语，如：it is advised/ suggested/ requested/ ordered/ proposed that…)、表语从句或同位语从句例如：It is required that the students (should) learn a foreign language. (主语从句) The requirement is that all the equipment in the meeting room (should) be checked twice before. (表语从句)We didn’t stand for his proposal that the meeting (should)be postponed. (同位语从句)只要看到句中有上述动词或其变体，不管词性怎么变、句型怎么变，都⽤be型虚拟！特例：suggest和insist这两个⽐较特殊，当suggest作“暗⽰、表明、说明”讲，insist作“坚持说”讲，后⾯⼀般跟的是客观事实，不需要虚拟~这是⼀个⽐较重要的考点，体会下⾯两组句⼦：We all suggest that a lab (should) be built. 我们都建议建⼀个实验室。
