混合虚拟语气辨析
混合虚拟语气辨析
1．名词从句中的虚拟语气标志词+should+动词原形
2．条件从句中的虚拟语气①三种基本态②倒装虚拟句③混时虚拟句④含蓄虚拟句⑤跳层虚拟句
3．其它情形中的虚拟语气（wish/would rather/It’s high time…/If only…/lest）
一．三种基本形态（1）
表虚拟的时间if从句谓语形式主句谓语形式
现在：did / were would (should, might, could)+do
过去：had done/ had been would (should/might/could)+have done(been)
将来：were to/ should+do would (should, might, could)+do
三种基本形态（2）（这是基础，建议牢记下面的例句，争取能脱口而出）
与现在事实相反：If I had enough money, I would buy a book.
与过去事实相反：If I had had enough money, I would have bought a book.
与将来事实相反：If I were to have enough money, I would buy a book.
If I should have enough money, I would buy a book.
二、倒装虚拟句（只能与过去/将来事实相反，省去if，只有三种倒装形式）
Had I had enough money, I would have bought a book.
Were I to have enough money, I would buy a book.
Should I have enough money, I would buy a book.
三、混合时间虚拟语气（主要是抓住时间状语）
(对过去事实虚拟+对现在事实虚拟)
If I had studied English at school, I could read the English novel now.
(对现在事实虚拟+对过去事实虚拟)
If she were not so careless, she wouldn’t have made such a mistake.
四、含蓄虚拟句（在四级考试中目前还未出现此考点，但在阅读中常见）
3. 虚拟语气用在主语从句中。在句型“It is important (necessary, strange, natural等) that...” 中，that 后面的从句中的谓语动词用(should) + 动词原形。
It's necessary that we should have a walk now. 我们现在有必要出去散散步。
What would I have done without you?
But for their help, I would not have finished the task.
But that the doctor arrived on time that day, they would have been dead.
Given more time, I would have been able to finish the test.
五、跳层虚拟句（即句子一半为虚拟，另一半为陈述语气；but前句用虚拟而or/otherwise后句用虚拟）(but)
He would put on weight, but he doesn't eat much. (与现在事实相反)
He would have put on weight, but he didn't eat much. (与过去事实相反)
(or, or else, otherwise)
I forget where I read the article, or I would show it to you now. (与现在事实相反)
Mary couldn't have received my letter, otherwise she would have replied before now. (与过去
事实相反)
六、名词从句虚拟语气
(1) ask, advise, beg, command, demand, decide, desire, insist, order, prefer, propose, require, recommend, request, suggest, urge等表示命令、要求、建议等含义的动词后的宾语从句中，谓语动词用(should)+动词原形, eg. I suggest / suggested that we (should) go tomorrow.名词从句虚拟语气
(2) It is +(形容词/过去分词/特定名词)+that的从句中，形容词主要是表示令人吃惊的、重要的、必要的、关键的等词汇。形容词：astonishing, amazing, advisable, appropriate, crucial, desirable, essential, important, imperative, keen, necessary, natural, normal, odd, proper, preferable, strange, sorry, shocked, surprising, urgent, unusual, vital等。名词从句虚拟语气
(3) 过去分词：decided, desired, demanded, ordered, requested, recommended, suggested等;名词：advice, decision, desire, demand, suggestion, motion, pray, resolution, wish, preference, proposal, recommendation, requirement, idea, order等
七、其它虚拟语气
Wish…
I wish I knew the answer.(与现在事实相反)
I wish I had known the answer. (与过去事实相反)
I wish you would shut up. (与将来事实相反)
If only…
If only I were taller. (与现在事实相反)
If only he had followed your advice! (与过去事实相反)
If only the rain would stop. (与将来事实相反)
It is (high/about) time…
It is time you thought about your future.
would rather…
I would rather you didn’t speak rudely to her. (与现在事实相反)
I’d rather you hadn’t spoken rudely to her. (与过去事实相反)
Lest…, in case…, for fear that…（引导的是目的状语从句，但可归入第六点(名词从句虚拟)，这是因它们答案特征相同，即(should)+动词原形。eg.
He took his umbrella lest it should rain.
大学英语虚拟语气考题总结:答案的特征
1.(should)+动词原形(一般式/被动式/否定式)记住信号词（名词，动词，形容词，分词等）以及lest.
2. 一般过去时：wish/If only…/would rather/It’s time (high/about) that….
3.基本形式（主要考与过去和将来相反的虚拟语气）,特别注意时间状语(混合时间虚拟)
4.倒装的两个时间：与过去，与将来相反；三个形式(Had/Were/Should)提前大写，if省去；
5.but/or/or else/otherwise(跳层虚拟语气)
虚拟语气在四级考试中是一个必考的考点。其中，最常考的是它在宾语从句中的用法。一些表示主观判断、推测、建议、命令和要求的动词通常引起虚拟的宾语从句，此类动词后的宾语从句中采用should ＋do（其中should可以省略）的虚拟语气形式。该类动词包括：
（1）高中词汇：advise（劝告）、ask（要求）、decide（决定）、insist（坚持）、order （命令）、suggest（建议）等。
（2）四级常考词汇：command（命令）、demand（要求）、desire（渴望）、prefer（宁愿）、propose（提议）、recommend（劝告）、require（要求）等。
（3）其他词汇：consent（同意）、maintain（主张）、move（提议）、urge（极力主张）、vote（提议）等。
例句：I recommend that you be diligent if you want to pass the exam．如果你们想考试及格，我劝你们勤奋学习。
特别提示：在复习时，可以把相似用法归类记忆。当一个动词后面的宾语从句中应使用（should）＋do的虚拟语气形式时，则可推理出用法相同的以下一组从句（以动词advise为例）：
（1）I advise that we stay and wait here．（动词后的宾语从句）
（2）It is advised that we stay here．（It is ＋动词的过去分词＋that引导的主语从句）（3）It is advisable that we stay here．（It is ＋由该动词派生的形容词＋that引导的主语从句）
（4）My advice is that we stay here．（由该动词转换的名词后面的表语从句）
（5）I offered the advice that we stay here．（由该动词转换的名词后面的同位语从句）（6）I think it advisable that we stay here．（由该动词转换的形容词作宾语补足语，it为形式宾语，真正的宾语从句中使用虚拟语气）
以上六类从句中谓语动词都使用了should ＋do的虚拟语气形式，其中，should可以省略。
由上类动词派生的常考名词有：advice（忠告）、deciion（决定）、demand（要求）、desire（渴望）、order（命令）、preference（偏爱）、proposal（建议）、recommendation（劝告）、requirement（要求）、suggestion（建议）等。
相关的形容词或过去分词有：advisable（合理的）、desired（期望的）、desirable（合乎需要的）、insistent（坚持的）、ordered（命令的）、preferable（更可取的）、proposed（建议的）、required（要求的）、urgent（紧迫的）等。
例句：His proposal is that we turn off TV for half an hour every day．（表语从句）他建议我们每天少看半个小时的电视。
It is highly desirable that a new president be appointed for this college．（主语从句）急需为这所大学任命一位新校长。

学习好资料欢迎下载 一．语气的定义和种类。 1语气 (mood) 语气是动词的一种形式，表示说话人对某一行为或事情的看法和态度。 2语气的种类 a. 陈述语气：表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句 和某些感叹句。如： There are two sides to every question. 每个问题都有两个方面。 Were you busy all day yesterday? 昨天一整天你都很忙吗？ How good a teacher she is!她是多好的一位老师啊！ b.祈使语气：表示说话人对对方的请求或命令。如： Never be late again! 再也不要迟到了。 Don’ t forget to turn off the light. 别忘了关灯。 c.虚拟语气：表示动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测 等。如： If I were a bird, I could fly in the air.如果我是一只小鸟，我就能在空中飞行。 对比： If I am a bird, I can fly in the sky. 二．虚拟语气在条件从句中的用法。 条件从句有两类，一是真实条件句，另一是虚拟条件句。如果假设的情况可能发生，是真实条 件句，这种情况下谓语用陈述语气。如： If time permits, we ’ ll go fishing together. 如果时间允许，我们就一起去钓鱼。 如果假设的情况是不存在的或不大可能发生的，则是虚拟条件句。如： If time permitted, we would go fishing together. （隐含的事实是：时间不允许，我们不会一起去 钓鱼）。 三．例句与练习： 1．表示与现在事实相反的假设和结果。 If I were you, I should(would ,could, might)tell him the truth.要是我是你，我就会告诉他 真相了。（事实上我不是你） If she had time, she would(could, might)help me.如果她有时间，她就会帮我。（事实上她 没有时间） 练习： 1, If the color of your dress ____ red, you _____ look more cheerful. 2, If I ____(have to) say something good about your work, I ______ say“ well done”.
真实条件句,虚拟语气.
当我们陈述了一个事实，而又不是很有把握，就可以在陈述句后加一个简短问句，称为反意疑问句。首先看以下例句：（1） You like calssical music, don't you? 你也喜欢古典音乐，对吗？(2 He lived in Vienna, too,didn't he? 他也住在维也纳，对吗？（3）Your parents can swim, can't they? 你父母会游泳，是吗？（4） Tony doesn't like classical music,does he? 托尼不喜欢古典音乐，对吗？（5） This music isn't very popular, is it? 这音乐并非十分流行，对吗？从以上句子可以看出，反意疑问句是由“助动词/ 系动词be（肯定或否定）+主语（代词）” 构成的。在反意疑问句的构成中要注意以下几点： 1.前面当陈述句如果是肯定的，反意疑问句就要用否定形式，如（1）、（2）、（3）；前面的陈述句如果是否定的，反意疑问句就要用肯定形式，如（4）、（5）； 2.反意疑问句的主语必须是代替前面主语的代词； 3.翻译疑问句的谓语动词在时态和人称上要与前面陈述句谓语动词保持一致。陈述句部分如果有标识否定意义的词，反意疑问句要用肯定式。如：They have never visited his home, have they? 他们从来没有到他家玩过，是吧？在回答反意疑问句时，要特别注意英、汉两种语言习惯的差别。试看下面当例句：——Mr Smith isn't American, is he? 史密斯先生不是美国人，对吧？——Oh yes, he is.不对，他是美国人。可以看出，在英语中，无论问题是怎样问的，只要答语的事实是肯定句，就要用YES；只要答语的事实是否定的，就要用NO. 编辑本段英语18种特殊的反意疑问句介绍 1.祈使句。祈使句后一般加上will you或won't you构成反意疑问句，用will you 多表示“请求”，用won't you 多表示提醒对方注意。例如：Look at the blackboard, will you/ won't you?看黑板，好吗？Let引导的祈使句有两种情况：1Let's...,后的反意疑问句用shall we或shan't we。例如：Let's go home, shall we/ shan't we? 回家吧，好吗？还可以用may I来表示征求对方的同意或许可。2Let us/me...后的反意疑问句用will you或won't you。例如： Let me have a try, will you/won't you? 让我试一试，行吗？ 2.感叹句。感叹句后加反意疑问句时，其反意疑问句需用be的一般现在时态的否定形式。例如：What fine weather, isn't it? 多好的天气啊，是吧？ 3. 当陈述部分谓语动词是need, dare, used to，且这些词被用作实义动词时，其反意疑问句需用do的适当形
虚拟语气中的含蓄条件句常见用法总结
虚拟语气中的含蓄条件句常见用法 先看一道高考题： ____ more attention，the trees could have grown better． A．Given B．To give C．Giving D．Having given （答案是A） 句中"．．．the trees could have grown better"是一个表达虚拟语气的句子。题中要求选择的是如何表达假设条件的形式。如果我们把这个句子用另一种形式"If they had been given more attentio n ，the trees could have grown better．"来表示，就不难理解了。很多情况下，在表示假设的虚拟语气中，有时假设的条件并不以条件从句的形式表达，而是通过上下文或句中内在的逻辑关系，或用其它形式表达出来，我们称之为"含蓄条件句"。 含蓄条件句主要通过名词、连接词、不定式、分词、动名词短语、介词短语及分句来暗示。这些表达形式在句中实际起着虚拟条件从句的作用。现分述如下： 一、介词短语 常用来表示虚拟条件的介词有with，without，in，under，but for等等，它们表示的虚拟条件都可以被if从句替换。 （1）without，with without表示否定的条件，意为if．．．not；with与without意义相反，表示肯定的条件。如：Without air，there would be no living things．（without air ＝if there were no air）没有空气，便没有生物。 With her help（＝If I had her help），I would do the experiment well．假如有她帮助，我就可以把这个实验做好。 （2）under Under the leadership of a less experienced person，the experiment would have failed．（u nder．．．＝If there had been the leadership of a less experienced person）假设在一个缺少经验的人领导下进行实验，实验准会失败。 （3）in I would have lost my head in that position．（in that position ＝if I had been in that po sition）我处在那种情况下，是会丧失理智的。 （4）but for

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。 ②从句的动作与现在事实相反，而主句的动作与过去事实不符。 If he were free today, we would have sent him to Beijing. 如果他今天有空的话，我们会已经派他去北京了。 If he knew her, he would have greeted her. 要是他认识她的话，他肯定会去问候她了。 5、当虚拟条件句的谓语动词含有were, should, had时，if可以省略，这时条件从句要用倒装语序，即把were, should, had等词置于句首，这种多用于书面语。 Should he agree to go there, we would send him there.要是他答应去的话，我们就派他去。 Were she here, she would agree with us.如果她在这儿的话，她会同意我们的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些电脑知识的话，我们已经聘用他来这里工作了。 【注意】 若条件从句为否定句，否定词not应置于主语之后，而不能与were，should，had 等缩略成Weren't，Shouldn't，Hadn't而置于句首。 Had it not been for the bad weather we would have arrived on time. 若不是天气坏，我们就准时到达了。 ②有时省略if后提前的had不是助动词: Had I time，I would come. 假若我有时间，我会来的。(=If I had time…) 6、非真实条件句中的条件从句有时不表达出来，暗含在副词、介词短语、上下文或其他方式表示出来，这种句子叫做含蓄条件句。 ①将条件会暗含在介词短语中，如without…, but for…,otherwise（要不是因为）等 But for his help, we would be working now.

if引导的条件句中的虚拟语气
if引导的条件句中的虚拟语气 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（Sentences of Real Condition）：凡是假设的情况发生性可能很大，就是真实条件句。例如： ⑴、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（Sentences of Unreal Condition）：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 h is old friend.假如他昨天来这儿的话，就会看见他的老朋友。 ⑴、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。 ②与现在事实相反，在从句中用过去一般时形式表示。 ③与将来事实可能相反，在从句中用过去将来时形式表示。 主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。例： ⑴、If I had come her yesterday, I would have seen him. ⑵、If I were a teacher, I would be strict with my stud ents. ⑶、If it should snow tomorrow, they couldn't go out. 4、注意事项 ①if条件句中如有were, should, had，可以省去if，并使用倒装语序。 ②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
虚拟语气中的含蓄条件句常见用法总结
虚拟语气中的含蓄条件句常见用法先看一道高考题： ___ more attention ，the trees could have grown better ． A．Given B．To give C．Giving D ．Having given (答案是A ) 句中" ．．．the trees could have grown better" 是一个表达虚拟语气的句子。题中要求选择的是如何表达假设条件的形式。如果我们把这个句子用另一种形式"If they had been given more attentio n ，the trees could have grown better ．" 来表示，就不难理解了。很多情况下，在表示假设的虚拟语气中，有时假设的条件并不以条件从句的形式表达，而是通过上下文或句中内在的逻辑关系，或用其它形式表达出来，我们称之为" 含蓄条件句" 。含蓄条件句主要通过名词、连接词、不定式、分词、动名词短语、介词短语及分句来暗示。这些表达形式在句中实际起着虚拟条件从句的作用。现分述如下：一、介词短语常用来表示虚拟条件的介词有with ，without ，in ，under ，but for 等等，它们表示的虚拟条件都可以被if 从句替换。 ( 1 ) without ，with without 表示否定的条件，意为if ．．．not ；with 与without 意义相反，表示肯定的条件。如： Without air , there would be no living things .(without air = if there were no air)没有空气，便没有生物。 With her help (= If I had her help )，I would do the experiment well ．假如有她帮助，我就可以把这个实验做好。 ( 2 ) under Under the leadership of a less experienced person ，the experiment would have failed ．( u nder ．．．= If there had been the leadership of a less experienced person )假设在一个缺 少经验的人领导下进行实验，实验准会失败。 (3 ) in I would have lost my head in that position ．( in that position = if I had been in that po sition )我处在那种情况下，是会丧失理智的。 ( 4 ) but for

虚拟语气用法总结
虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达： a. 非真实的情景，不可能发生的事，即某种与事实相反或难以实现的情况，或说话人主观愿望。 b. 与客观事实相反地情景，即强制性虚拟语气，表示建议、命令、劝告这一类的意思上，表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的，其特点是主从句时态的不一致，而且一般有明显得标志。 二.虚拟语气的考点为： 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反：从句用一般过去时，主句的谓语用would (could, might) ＋动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反：从句用过去完成时，主句的谓语用would (could, might) ＋现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反：从句用should (were to，did) + 动词原形，主句的谓语用would (could, might) ＋动词原形 If it should/were to snow tomorrow, I would go skiing.
注意：虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.混合条件句主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…，要是…多好”的语气表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为： He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形，其中should 经常被省略。这类动词包括： suggest, propose, recommend, demand, order, command, desire, require, insist,
高中英语破题致胜微方法(虚拟语气)虚拟语气之含蓄条件句
虚拟语气之含蓄条件句 “含蓄条件句”是指用介词短语的形式，起到代替条件句的作用。主句中的谓语动词仍可象虚拟条件句那样采用各种虚拟式。常使用的介词短语由but for, without构成。 一. 典型例句 1. Without air, human being would not be able to survive. = If there were no air, human being would not be able to survive. 如果没有空气，人类将无法生存。（与现在事实相反） 2. The ship would have sunk with all on board but for the efforts of the caprain. =If it had not been the efforts of the caprain, the ship would have sunk with all on board. 要不是船长的努力，我们就会连船带人都沉没了。（与过去事实相反） 注意： without, but for暗示了条件，所以相当于虚拟条件句中的从句，它们所在的句子主干相当于虚拟条件句中的主句，所以谓语动词的形式应该和虚拟条件句中的主句谓语动词形式相同。 二. 例题 1. Without the air to hold some of the sun’s heat, the earth at night _________, too cold for us to live. A. would be freezing cold B. will be freezing cold C. can be freezing cold D. is freezing cold 2. But for the English examination, I ________________last Sunday. A.went to the concert B. would have gone to the concert C.would go to the concert D. had gone to the concert 三. 总结
