在虚拟语气重，一般过去时通常表示与现在事实相反，过去完成时表示与过去事实相反。
整体来说，虚拟语气是一种表示假设状态的句型，表示所说的话不是事实，而是一种假设，愿望，建议。
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。 Her expression suggests that she is angry. 她的表情说明她生气了。 She insisted that we should find the source of the river. 她坚持主张我们应该找到河的源头。 She insisted that she had done nothing wrong. 她坚持说自己没做错事。 suggest 的区别很明显，但insist有点难辨别，一般来说如果insist后面跟的是某种主张，或是坚持要做一件事，那么用虚拟。 2）表示主观看法，常表示“某事是必要的、重要的。。。怎么怎么样的”，尤其是在“ it is +名词/形容词+ that从句”结构中，常见的形容词包括：advisable, desirable, essential, imperative, important, necessary, obligatory, proper, dispensable, impossible, natural, surprising等 例如：It is advisable that you (should) leave now. It is necessary that teenagers (should) take part in outside activities. It is of great importance that smoking (should) be banned in public area.
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。 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 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： Were it to rain tomorrow, our picnic would be canceled. Had it not been for the storm, we would have arrived in time. Should the earth stop running, what would happen? 二. 错综时间条件句 有时条件从句的动作和主句动作发生的时间不一致，这时需要根据意思采用表示不同时间的动词形式来进行调整。 If she had taken the doctor’s advice, she might still be alive. If I were you, I would have accepted their terms. 三．含蓄条件句
高中英语语法讲解--虚拟语气 1. 语气的定义和种类 （1）语气的定义 语气是动词的一种形式，它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。 We are not ready. Did it rain all day yesterday? What a fine day today！ B. 祈使语气 表使说话人的建议、请求、邀请、命令等。 Be careful. Don’t forget to clo se the window. Open the door, please. C. 虚拟语气 表使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。 2. 虚拟语气 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语气。 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。 如：She would have gone to the party if she had been invited.
虚拟语气在as if/as though引导的方式状语从句中1.表示与现在事实相反或对现在情况有怀疑，谓语动词用过去式。 He treats the boy as if he were his own son. 2.表示与过去事实相反，谓语动词用过去完成时。 He spoke as if he had known about it. 3．表示与将来事实相反，(表示将来的可能性不大),用would (might, could)+动词原形 He acts as if he could win in the game . 注意：1.在as if/as though 句中，如果有可能成为事实，用陈述语气。 例：He looks as if he going to be ill. 2.as though或as if引导的状语从句，从句主语和主句主语相同时，从句中可省略主语和部分谓语。 虚拟语气用在lest，for fear that，so that及in order that引导的目的状语从句中表示“以防，以免”等意思谓语动词多用should/could/might+动词原型构成 For fear that it may rain tomorrow, we should bring an umbrella. 由“providing（that） /provided（that）/on condition that/suppose （that）/supposing （that）”引导的条件从句根据情况，1.可以用虚拟语气。 例：suppose/supposing that it rained,we shouldn’t go out. 2.也可以用陈述语气。 例：They are willing to surrender provided they are given free pardon..

Work ! (2). Work harder ! (3). Be more alert ! (虚拟语气动词Be) (4). You go out ! (5). Do not work so hard. (do not 表示否定的虚拟语气) (6). Don't be afraid. (口语中常用don't 代替do not) 五、在一些习惯表达中。如： (1).You’d better set off now.你最好现在就出发。 (2).I’d rather not tell you the secret.我情愿不告诉你这个秘密。 第三部分：名词性从句中的虚拟语气 第一节：宾语从句(Subordinate Clause)中的虚拟语气 一、在动词wish后的宾语从句中的虚拟语气 在动词wish后的宾语从句中的虚拟语气，常省去宾语从句的引导词that。 一）、对现在情况的虚拟（与现在的事实相反）： 从句用过去式或过去进行式(时间上是同时的)。其句子结构为：宾语从句的谓语be和were(was)，实义动词用过去式。例： 1. I wish (that可省略,下同)I knew the answer to the question.(wish, 动词过去式knew)我希望知道这个答案。(事实上是不知道) 2. I wish it were spring in my hometown all the year around.(wish, were)但愿我的家乡四季如春。(事实上不可能) 3.

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,

If I had seen the film, I would….. (2) 虚拟语气过去式. 表示与过去事实完全相反的假设. Eg. If we had started earlier， we should not have missed the train. If she hadn’t been ill， she might have come. If she were not ill， she might come.
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) 8. If Lily didn’t attend today’s party, she could not have the chance to work in the company next week. (从句是对现在的假设，主句是对将来的假设) 9.

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)
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
