虚拟语气的用法荟萃
一：概念：虚拟语气是指和现实情况相反的假设，是对真实情况的主观臆想或是一种主观愿望。
二：虚拟语气涉及的情况：
1)用在由if引导的非真实条件句中。条件句分为真实条件句和非真实条件句。
A)真实条件句：即条件是可实现的客观事实或者真实情况。
如：If you heat ice, it melts.(融化)
If I make a promise, I keep it.
If we catch the early bus, we will(shall,can, may,)get there by lunch time.
If it is fine tomorrow, we can play basketball.(客观事实)
If it rains, I go to school on foot.
☆B)If 引导的非真实条件句中，即虚拟条件句中。主要涉及到对三种情况的虚拟：对过去的虚拟；对现在的虚拟；对将来的虚拟。谓语动词的时态变化符合“倒退一步法”。
①对过去真实情况的虚拟，或者对过去事实完全相反的假设：
公式：
if…had + V-ed分词（从句）, …Would（could,might,should）+ have+ V-ed分词…（主句）如：If we had started earlier, we should not have missed the train.
If she hadn’t been ill, she might have come.
If they had helped us, we would have finished the task. (实际上没帮)
If I had made good prepatation, I wouldn't have lost the job.
②对现在真实情况的虚拟，或者对现在真实情况相反的假设：
公式：
If ...+V-过去式(be多用were),...+would/should/could/might + 动词原形
If I were a bird, I would fly to the top of Mount Hua.
If I had time, I would go to the movies with you. (实际上没时间)
If I had enough money, I would buy that new toy for you.
③对将来情况相反的假设：
公式：
If 。。。+动词过去式/should +动词原形/were to +动词原形,。。。+would/should/could/might +动词原形
If it should/were to/ rain tomorrow, I would stay at home.(下雨的可能性很小)
If Kobe should come to our village, I would take photos with him.
※注意：虚拟语气的倒装语序：上述(1),(2),(3)三种时态的虚拟句中,如果if从句里含有should, had, were或其他助动词,则可将从属连词if省去,将助动词.情态动词.be或have放在句首形成部分倒装.
If I had time, I would have done that yesterday.
==Had I had time, I would have done that yesterday.
If I were you, I would go to the party.
==Were I you, I would go to the party.
If it should rain tomorrow, I would stay at home
==Should it rain tomorrow, I would stay at home.
2）错综时间if虚拟条件句
通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的, 但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式.
如：If I were you, I would have taken his advice. (从句指一般情况, 主句指过去)
If I had taken my raincoat with me this morning, I would not be wet now. (从句指过去,主句指现在).
If I had bought that ticket last night, I would go to the theater(剧院) with you tomorrow.
3）that从句及其他特殊句型中的虚拟语气：
A)在suggest, order（命令）demand（要求）,request（要求），require（要求），propose （建议）,move（提议），command,（指挥）, recommend（推荐）, decide, insist（坚持）, desire（渴望）, urge（督促）等动词后的宾语从句中要用“ (should) +动词原形” 来表示愿望,建议, 命令,要求等;
注意：由上述动词派生或转化的名词形式，如suggestion, proposal, plan, motion, recommendation, demand, order, desire, request, requirement, insistence, advice, decision , ）等的同位语从句或表语从句中也要用相应的虚拟形式.
如：
宾语从句如下表：
He ordered （that）all the books (should) be sent at once.
I propose that he (should) be chosen as the monitor(班长)
The teacher demanded that all the students (should) hand in their notebooks after class.
The doctor insisted/decided that he (should) not eat meat.
表语从句及同位语从句如下表：
His order was that all the books (should) be sent at once.(表语从句)
He gave the order that all the books (should) be sent at once.(同位语从句)
My propose was that he should be chosen as the monitor.(表语从句)
The teacher's demand was that all the students should hand in their notebooks after class.（表语从句）
The doctor's decision that he should not eat meat was reasonable(合理的).
B) 在It is/was + 某些形容词+ that 从句的句型中,that从句中的谓语动词常用虚拟语气,即“should + 动词原形”。这些形容词有:
important, necessary（必要的）, essential（关键的，及其重要的）, imperative（必需的）, natural, strange, advisable（可取的，明智的）, desirable（可取的）, possible, probable（很可能的）, astonishing（令人震惊的）, surprising, desired, suggested（被建议的）, requested,（被要求的）recommended（被推荐的）, ordered, proposed, decided, obligatory（义不容辞的, 必须的),moved （被提议的）等.
如：
It is necessary/essential/imperative/important that he should be given the chance.
It's ordered that he should come back without delay.(他被命令不许回来迟了。)
It's very essential that we should learn to speak English under the background of economic globalization.
It's advisable that he should take part in the party.
※注意：should + 动词原形(或完成形式)” 可表示惊奇,遗憾,怀疑,不满等。
I. 用于expect, believe, think, suspect 等动词的否定或疑问形式后的宾语从句中.
如：I never expected that the new apartment should be so small.
II. 用于“It is a pity, it is a shame, it is no wonder 等+ that” 等结构后的主语从句中.
如：It is a pity that he should be so careless.
III.在由for fear that, in case, lest（以防）等引导的状语从句中,用“ should + 动词原形” 表示“惟恐，防备，推测”的意思.should可以省略。
Eg. He handled the instrument with care for fear that it should be damaged.
He walked out of the room quietly lest his mother should notice him.
4）用在wish之后的宾语从句中。
①表示现在的愿望，从句谓语用一般过去时，be换成were
I wish I were not at the party.我希望现在自己没在这个晚会上。
②表示过去的愿望，从句谓语用过去完成时或could have + V.ed
I wish I had studied harder last term.我希望上学期我学习更努力就好了。
③表示将来不大可能实现的愿望，从句谓语用would + V.
I wish he would invite me to the party this weekend.
5)用在It is about(high)time+ that从句中（表示应该做，但还没做）。That从句的谓语用一般过去时，that可省略。如：
It’s high time we went to bed.
6)在would rather, would sooner(宁愿), would just as soon(宁愿)的宾语从句中，从句谓语动词有两种情况：
①表示现在或将来虚拟时，谓语一般都用一般过去时；如：
I would rather you came next week instead of today.
②表示过去虚拟用过去完成时。如；
I would rather that I hadn’t finished the task.
7)在“as if/ as though” 引导的状语从句中,谓语动词与wish的宾语从句的虚拟形式相同.
如：He works with such enthusiasm（热情）as if he never knew fatigue（疲劳）.
He speaks English as though he were an American.
注意：若as if从句表示的是真实情况，则不用虚拟语气，照常用陈述语气。
如：
It seems as if they know each other. (真实情况)
It seems as though it were already spring. (虚拟语气)
8）用在if only （要是。。。就好了）引起的感叹句中.
Eg. If only the driver didn’t drive so fast!要是他没开这么快就好了。
If only I were not so nervous.(紧张的)要是我现在不紧张就好了。
9)用于含蓄条件句。当句中中带有介词如“but for”,"without"表示“要不是”，“否则”等，虚拟语气的使用。如：
But for your advice, I could not have done it so successfully.
Without electricity, we would live a boring life.
虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it. If you had taken your teacher’s advice, you wouldn’t have made such a mistake. If it were to/ should rain tomorrow(表示降水率很低)，they wouldn’t go shopping. 附注： 虚拟语气，条件状从倒装 状语从句中，去掉if,提前were/ had/ should 如：If I were you, I would give up. →Were I you, I would give up If you had taken the advice, you would have…. →Had you taken the advice, you would have… If the world shou ld come to an end,…… →Should the world come to an end…… 另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (popularization 普及，publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.（表示可能性小）

虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 语气的种类： （1）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We are ready. What a fine day it is! （2）祈使语气表示说话人的建议，请求，邀请，命令等。如Open the door, Please. 应注意以下几点： 1.主语通常是第二人称you，但多不出现，动词用原形，否定用do not 或者don’t 加动词 原形（或be）如Be careful next time. Don’t smoke here. 2.有时为了强调，主语也可以出现，而且可以是第三人称，谓语动词不加-s或者-es如You be quiet. He stand up. 3.祈使语气可以用do加强语气如Do come to see this Sunday. 4.在Let’s 的祈使句后，疑问部分通常用shall we；在Let us后，疑问部分用will you 如Let’s go out for a walk after supper，shall we? /Let us clean our classroom, will you? 5.祈使句与连词and连用时相当于一个条件句，而and之后则是表示结果。如Think hard and you will have a good idea. （3）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 you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气，列表如下： 例如：If he were here, everything would be all right. If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if，采用局部倒装语序。把had /should/were 等动词（不包括行为动词）移到从句的句首。例如：
二、虚拟语气的判断： 1. if 条件状语从句中虚拟语气的判断。if 条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句，反之为非真实条件句，要用虚拟语气。其形式分为以下三种： (1) 与过去事实相反的假设。结构为：从句的谓语动词用“had + 过去分词”，主句用“should (would, could, might) + have + 过去分词”。例如： If it had not rained so hard yesterday, we could have played tennis. 如果昨天没有下大雨，我们就能玩网球了。 (2) 与现在事实相反的假设。结构为：从句的谓语动词用过去式，系动词用were，主句的谓语用“should (would, could, might) + 动词原形”。例如： If I were in your position, I would marry her. 如果我是你，我就娶她为妻。 (3) 与将来事实相反的假设。结构为：从句的谓语动词用“should (were to) + 动词原形”，主句用“should (would, could, might) + 动词原形”。例如： If you should miss the chance, you would feel sorry for it. 如果你错过了这次机会，你会难过的。 2. 宾语从句中的虚拟语气。 (1) wish后接宾语从句中的虚拟语气：根据从句的意义来判断。 A: 表示与现在和将来事实相反的愿望，从句谓语动词用过去时态。例如： I wish they were not so late. 要是他们来得不是这么晚就好了。 B: 表示与过去事实相反的愿望，从句谓语动词用过去完成时态。例如： I wished he hadn't done that. 我真希望那件事不是他做的。 (2) 表示“要求、建议、命令”等动词后面的宾语从句中的虚拟语气。用于此结构的动词有：advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest 等。从句的谓语动词用“should + 动词原形”，其中should 可以省去。例如： I insisted that he (should) go with us. 我坚持让他和我们一起去。 注意：当insist 表示“坚持认为”、suggest表示“表明，显示”时，不用虚拟语气。例如：

虚拟语气用法 虚拟语气用法
概念
虚拟语气用来表示说话人的主观愿望或假想， 而不表示客观存在的事实， 所说的是一个条件， 不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。英语中的语气分 为陈述语气、祈使语气、虚拟语气三类。
应用条件
在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或 某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的 主观想法，而不是根据客观实际，就用虚拟语气。
在非真实条件状语从句中的用法
真实条件状语从句与非真实条件状语从句
条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表 示的是假设或实际可能性不大的情况，故采用虚拟语气。 例： If he doesn’t hurry up, he will miss the bus. 如果他不快点，他 将错过巴士。( 真实) If he is free, he will ask me to tell stories. 如果 他是空闲的，他会要求我讲故事。 （真实） If I were you, I would go at once. 如果我是你， 我马上就会去。（非真实， 虚拟语气） If there were no air, people would die. 如果没有空气，人就会死亡。 （非真实，虚拟语气）

虚拟语气用法详解 一、条件句中的虚拟语气 1. 条件句中虚拟语气的形式 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，主句会产生的一种不可能获得的结果。条件句中 的虚拟语气根据不同的时间有三种不同的形式。 2. 条件句中的虚拟语气的举例 (1) 将来时的条件句中的虚拟语气。如： If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话，他就会充分 利用他的时间了。 If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。 (2) 现在时的条件句中的虚拟语气。如： If he were free, he would help us. 要是他有空的话，它会帮助我们的。 If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。 (3) 过去时的条件句中的虚拟语气。如： If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。 If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿，我就会会到了李先生。 3. 运用条件句中的虚拟语气时，须注意的几个问题 (1) 当从句的主语为第三人称单数时，谓语动词若是系动词be 时，可用was 代替were。但在倒装虚拟结构及if I were you, as it were 中，只能用were。如： Were I ten years younger, I would study abroad. 要是我还年轻十岁的话，我会去国外学习。 If I were you, I would try my best to grasp the chance. 要是我是你的话，我要尽力抓住这次机会。 (2) 有时，虚拟条件句中，主、从句的动作若不是同时发生时，须区别对待。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。如： 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，我现在也会使工程师了 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。
高中英语虚拟语气的用法 一、考查虚拟语气在条件从句中的用法 时间从句谓语形式（be用were不可改变）主句谓语形式 将来一般过去时(be用were) would/should/might/could+动词原形 现在一般过去时(be用were) would/should/might/could+动词原形 过去现在完成时would/should/might/could+had done （1）If he my advice, he wouldn' t have lost his job. A. followed B. should follow C. had followed D. would follow （2）If we the other road, we might have arrived here in time for the meeting. A. taken B. had taken C. took D. have taken （3） -John went to the hospital alone. -If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told 二、考查特殊句型中的虚拟语气 英语中需要使用虚拟语气的特殊句型不多，主理有以下类: 1.“倒装”类虚拟语气 当虚拟条件句中含有were, should, had时,有时可将引导虚拟条件句的连词if省略,而将从句中的were,should, had提到句首,构成倒装形式的虚拟语气。如: If he were here, she would agree too.→Were she here, she would agree too.如果她在这里,她也同意的。. If it should rain tomorrow, we should have to put off the match. →Should it rain tomorrow, we should have to put off the match.假若明天下雨,我们只好推迟这场比赛。 If we had found him earlier we could have saved his life.→Had we 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。 注意,如果条件从句的谓语为否定式,其中的否定词not应置于主语之后,而不能与were,should, had等缩略成Weren' t, Shouldn' t, Hadn'场置于句首。如:我如不是警告了你,你就可能丧命了。 正: If I hadn' t warned you, you could have been killed. 正: Had I not warned you, you could have been killed. 误: Hadn' t I warned you, you could have been killed. 另外,有时省略if后提前到句首的had可能不是助动词,而是实义动词。 如: Had I time, I would go with you.假如我有时间,我就同你们一起去。句中的had不是构成过去完成时的助动词,而是表示“有”,如果不省略if ,完整形式为:If I had time, I would go with you. (1) Had I known about this computer program, a huge amount of time and energy____. (2010浙江卷) A.would have been saved B. had been saved C. will be saved D. was saved （2） fired, your health care and other benefits will not be immediately cut off. (2006湖北） A. Would you be B. Should you be C. Could you be D. Might you be 2.“宁愿”类虚拟语气 这里说的“宁愿”主要是指would rather。当它后接句子的时候,句子的谓语通常要用虚

连云港育青外国语学校李老师谈英语中虚拟语气的用法 虚拟，在汉语中表示一种假设的，不存在的情况，同样，英语中虚拟语气是用来表示说话人 的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事 实相反。虚拟语气通过谓语动词的特殊形式来表示。在初中阶段，虚拟语气一般用于下列情况： 一、条件状语从句 1、与现在事实相反 若与现在事实相反，虚拟语气的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”。如： If I were you, I would take an umbrella. 如果我是你，我会带把伞。（事实上我不可能是你） 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。 (事实上我不知道) 2、与过去事实相反 若与过去事实相反，从句：主语+had done ，主句：主语+should/would/could/might+have done，例如： 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 I had got there earlier, I should/could have met her. 如果我早到那儿，我就会见到她。（事实：去晚了） 3、与将来事实相反 从句：①if+主语+were to do 主句：①主语+should/would/could/might+do ②if+主语+did/were ②主语+should/would/could/might+do ③if+主语+should+do ③主语+should/would/could/might+do 例如：If he went，would you go too? 如果他去，你也去吗?(大概他不会去) If he should come here tomorrow, I would talk to him. 如果他明天来这儿的话，我就跟他 谈谈。（事实：来的可能性很小） 注意与说明：对于与将来事实相反的情形，请注意以下几点： 一是这里说的与将来事实相反，实为对将来情况的推测； 二是此用法中的条件从句谓语除用过去式外，有时也用“should+动词原形”（ 表示可能性极小， 表示与将来事实相反的假设)； 常译为“万一”） 或“were to+动词原形”（ 三是当条件从句使用“should+动词原形”这样的谓语时，主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气外，也可用陈述语气或祈使语气。如： I should see him, I'll tell him. 万一我见到他，我就告诉他。 万一明天下雨，就别等我了。 If it should rain tomorrow, don’t expect me. 二、wish 后宾语从句 1、表示与现在事实相反的愿望，谓语动词用过去式。例如： I wish I had your brains. 我希望我有你那样的头脑。(事实：我根本比不上你) 2、表示与过去事实相反的愿望，谓语动词：had+done 例如： I wish I had knownthe truth of the matter. 我希望我那时就知道这件事情的真相。（事实：那时还不知道） 3、表示将来难以实现的愿望，谓语动词：should/would（情态动词）+ 动词原形 I wish I should havea chance again. 我希望我还能有一次这样的机会。（事实：很难再有 这样的机会了） 常见考法
实用英语虚拟语气的解析及其用法讲解 在当前英语语法当中，有一些学生总结的几个难点语法，其中之一就是虚拟语气，怎样判断出句子使用了虚拟语气，是哪一种形式的虚拟语气是学生无法清楚掌握的难点。本文从虚拟语气的定义到各种形式都进行了详细的讲解和分析，并针对各种形式的用法都进行了分析和举例，讲解明白，以帮助学生们能更好地了解和掌握英语语法中这个难学的语言现象。 标签：英语虚拟语气；定义；用法；分析及举例 一、虚拟语气的定义（Subjunctive Mood） 在我们了解什么是虚拟语气前，大家首先要弄清楚英语的语气表达，也就是英语学习中我们都会用到哪些语气。英语中的语气（Mood）可以分为：1The Indicative Mood（陈述语气）；2The Interrogative Mood（疑问语气）；3The Imperative Mood（祈使语气）；4The Subjunctive Mood（虚拟语气）4类。陈述、疑问、祈使语气在本文中就不再过多阐述。而我们在这里重点讲解虚拟语气。什么是虚拟语气呢？虚拟语气用来表示假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。虚拟语气表示说话者所说的话并非事实，或难以实现的，甚至表达相反的概念。另外表示主观愿望或表达某种强烈的感情时，也用虚拟语气。 二、虚拟语气的判断及用法 （一）if条件状语从句中虚拟语气的判断 if条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句，反之为非真实条件句，要用虚拟语气。其形式分为以下三种：1与过去事实相反的假设。结构为：从句的谓语动词用“had+过去分词”，主句用“should（would，could，might）+have+过去分词”。 2与现在事实相反的假设。结构为：从句的谓语动词用过去式，系动词用were，主句的谓语用“should（would，could，might）+动词原形”。 3与将来事实相反的假设。结构为：从句的谓语动词用“should（wereto）+动词原形”，主句用“should（would，could，might）+动词原形”。 （二）宾语从句中的虚拟语气 1wish后接宾语从句中的虚拟语气：根据从句的意义来判断 A：表示与现在和将来事实相反的愿望，从句谓语动词用过去时态。例如：

虚拟语气用法归纳 虚拟语气主要指的的是带有非真实条件状语从句的复合句，表达的是说话人的遗憾后悔的语气，愿望以及建议，命令，要求等等的情感，往往说的是与事实相反或者没办法实现改变的东西。虚拟语气主要表现为在对过去现在或者将来的情况做出假设后，有可能出现的情况。 虚拟语气的内容主要有三大模块，第一模块就是涉及到条件从句部分的内容。这一部分的虚拟语气主要体现在三个方面：基本用法，各自为政，以及含蓄之美。 下表就是条件从句虚拟语气的基本用法： 通常，在上面表格里反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，如果两者时间不一致，此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”，即从句和主句根据各自假设的时间不同，采用上面表格中对应的的谓语动词形式。 如何“各自为政”呢这就像是数学里的排列组合，一边有三种情况，交叉一搭配就出现了好多种情况。不管怎样，我们要遵循一个原则，就是“各自为政”。例如，从句是对过去情况的假设，而主句则是对现在情况的假设，那我们在使用时，从句就用过去完成式，而主句要用
would/could do的形式。当然，也不是所有的AB配就是合理的，有时候在具体语境下，会出现矛盾的情况，这时我们就要结合要表达的意思来 判断他们是对什么情况的假设，选择合适的形式。一般而言，主句的假 设时间会发生在从句的假设时间之后。因为是有这么一个条件才会出现 主句的现状。因此在此类的完成句子练习中，我们要特别提醒注意时间 状语的暗示 1. If I had seen you, I would not be so worried now. (从句是对过去的假设，主句是对现在的假设) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设，主句是对现在的假设) 3. If I were you, I would seize the chance to go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设，主句是对现在的假设) 5. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设，主句是对将来的假设) 6. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设，主句是对现在的假设) 7. If Jack hadn’t met Rose on his voyage, he would be alive now. (从句是对过去的假设，主句是对现在的假设)
英语虚拟语气用法详解 1. 英语语气的概念 英语有三种语气，即陈述语气、祈使语气和虚拟语气。陈述语气用于陈述事实、提出看法或问题等，祈使语气用于表示请求、命令或警告等，虚拟语气则表示假想或主观愿望。如： I like this book the best. 我最喜欢这本书。(陈述语气) Don’t be so careless. 不要如此粗心大意。(祈使语气) I suggest that we should go tomorrow. 我建议我们明天走。(虚拟语气) If you dropped the glass, it would break. 假如你把玻璃杯掉在地上，它会打碎的。(虚拟语气) 3. 虚拟条件句的基本类型 (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”。如： If we left now, we should arrive in good time. 假如我们现在就走的话，我们就会及时到达。 (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, coul d, might)+have+过去分词”。如： If he had been in that train then, he might have been k illed in that accident. 如果当时他也在那列火车上，他可能就死于那场车祸了。
(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”。如： 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) 3. 错综时间虚拟条件句 所谓错综时间虚拟条件句即条件从句与主句所指时间不一致，如从句指过去，而主句即指的是现在或将来，此时应根据具体的语境情况，结合上面提到的三种基本类型对时态作相应的调整。如：If you’d listened to me, you wouldn’t be in such tro uble now. 如果你听了我的话，你现在也不会有这样的麻烦了。 If you were in better health, we’d have let you go wit h us. 你要是身体好一点，我们就让你和我们一道去了。 4. 含蓄虚拟条件句 所谓含蓄虚拟条件句即指将条件从句隐藏在上下文一定的短语中的一类条件句。如： Anybody else would have believed you. 任何别人都会相信你的话了。 Without your help, I couldn’t have achieved all this. 要不是有你帮助，我不会取得这些成就。 I would have written before, but I have been ill. 我本想给你写信的，但我生病了。 5. if it weren’t (wasn’t) for与if it hadn’t been for
虚拟语气在非真实条件句中
①错综时间条件句: 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，被称为错综时间条件句，动词的形式要根据它表示的时间作出相应的调整。如： If you had followed my advice just now, you would be better now. If you had studied hard before, you would be a college student now. ②if省略句 在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。如：If I were at school again, I would study harder. →Were I at school again, I would study harder. 如果我还有上学的机会，我会更加努力学习。 If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你来得早点，你就能赶上公共汽车。 If it should rain tomorrow, we would not go climbing. →Should it rain tomorrow, we would not go climbing. 如果明天下雨的话，我们就不能登山去了。 ③用介词代替条件状语从句 常用的介词有with, without, but for。如： What would you do with a million dollars? (=if you had a million dollars) 如果你有100万元，你会做什么？ We couldn?t have finished the work ahead of time without your help. (=if we

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
