虚拟语气的用法归纳
1、虚拟条件句的三种基本类型：与现在事实相反、与过去事实相反、与将来事实相反。
条件句有真实条件句和非真实(虚拟)条件句两种。真实条件句所表示的假设是有可能发生的，而非真实条件句则通常表示一种假想，与事实相反或不大可能会发生：
If I have time, I will go with them. 假若我有时间，我就同他们去。(陈述语气)
If I were you, I would go with them. 假若我是你，我就同他们去。(虚拟语气)
▲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”：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。(可惜我不知道)
▲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, could, might)+have+过去分词”：
If I’d left sooner，I’d h ave been on time. 要是我早点动身，我就准时到了。(但我动身太迟了)
▲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”：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)
注：几点特别说明
①主句谓语中的should主要用于第一人称后。would, might, could的大致区别是：would表示结果，might表示可能性，could 表示能力、允许或可能性。比较：
If you tried again ，you would succeed. 要是你再试一试，你就会成功的。(would表结果)
If you tried again， you might succeed. 要是你再试一试，你可能会成功的。(might表可能)
If you tried again ，you could succeed. 要是你再试一试，你就能成功了。(could表能力)
④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，常译为“万一”)或“were to+动词原形”(表示与将来事实相反的假设)；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，也可用直陈语气或祈使语气：
If it should rain tomorrow, don’t expect me. 万一明天下雨，就不要等我了。（祈使语气）
If I should see him, I’ll tell him. 万一我见到他，我就告诉他。（直陈语气）
2、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：
If it had rained last night, the ground would be wet now. 要是昨晚下过雨的话，现在地面就会是湿的。
You would be much better now if you had taken my advice. 假若你当时听我的话，你现在就会好多了。
3、两个常考虚拟语气句型
▲句型介绍
这两个句型是If it weren’t for…和If it hadn’t been for…，这是两个很常用的虚拟语气句型，也经常受到命题人的青睐，其意为“若不是(有)”“要不是有”。如：
If it weren’t for water, no plant could grow. 要是没有水植物就无法生长。
If it hadn’t been for your assistance ，we wouldn’t have succeeded.
=But for your assistance ，we wouldn’t have succeeded.
=Without your assistance ，we wouldn’t have succeeded.
5、wish后宾语从句用虚拟语气
▲用法说明
动词wish后接宾语从句时，从句谓语要用虚拟语气。若要表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；若表示与过去相反的愿望，从句谓语用过去完成时或would / could+have +过去分词；若表示将来没有把握或不太可能实现的愿望，用would (could)＋动词原形。如：
注：特别注意
从句的时态只与从句所指的时间有关，而与wish的时态无关，比较：
I wish I were rich. 要是我现在有钱就好了。
I wish I had been rich. 要是那时我有钱就好了。
I wished I were rich. 当时我后悔自己没有钱。
I wished I had been rich. 当时我后悔自己曾经没有钱。
6、if only后的句子用虚拟语气
if only 与 I wish一样，也用于表示与事实相反的愿望，其后所虚拟语气的时态与 wish后所接时态的情况相同：
If only she had had more courage! 她再勇敢一些就好了。
If only I had listened to my parents! 我要是当时听了父母的话就好了。
If only she would go with me! 她要是愿意和我一道去就好了!
注：if only 通常独立使用，没有主句。
7、as if (though) 从句用虚拟语气
▲基本用法
以as if (as though)引导的方式状语从句或表语从句，有时用虚拟语气，若表示与现在事实相反，谓语动词用一般过去时；若表示与过去事实相反，用过去完成时；表示将来的可能性不大，用would (might, could)+动词原形：
He acts as if he knew me. 他显得认识我似的。
They treat me as though I were a stranger. 他们待我如陌生人。
He talks as if he had been abroad. 他说起话来好像曾经出过国。
注：两点说明
(1)从句所表示的内容若为事实或可能为事实，也可用陈述语气：
It looks as if we’ll be late. 我们似乎要迟到了。
(2)注意It isn’t as if…的翻译：
It isn’t as if he were poor. 他不像穷的样子(或他又不穷)。
8、It’s time后的从句用虚拟语气
▲基本用法
从句谓语通常用过去式表示现在或将来，有时也用过去进行时或“should+动词原形”(较少见，且should不能省略)，其意为“(早)该干某事了”：
It’s time we went [were going, should go]. 我们该走了。
It’s time I was in bed. 我该上床睡了。(不用were)
9、would rather后句子用虚拟语气
在would rather, would sooner, would just as soon 后的that从句中, 句子谓语习惯上要用虚拟语气，表示”宁愿做什么” ，具体用法为：
▲一般过去时表示现在或将来的愿望
I’d rather you went tomorrow (now). 我宁愿你明天(现在)去。
▲用过去完成时表过去的愿望
I’d rather you hadn’t said it. 我真希望你没有这样说过。
10、宾语从句用虚拟语气的10种类型
▲ I wish后的宾语从句
动词wish后接宾语从句时，从句谓语要用虚拟语气。若要表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；若表示与过去相反的愿望，从句谓语用过去完成时或would / could+have +过去分词；若表示将来没有把握或不太可能实现的愿望，用would (could)＋动词原形。如：
I wish I could be of some use. 我希望我能有什么用处。
We wish he didn’t smoke. 我们希望他不吸烟。
I wish prices would come down. 我希望物价能降下来。
▲表示“坚持”后的宾语从句
主要是指insist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。如：
I insisted that he (should) stay. 我坚持要他留下。
注：动词insist后接宾语从句时，除可用虚拟语气外，也可用陈述语气，两者的区别是：若谓语动词所表示的动作尚未发生，或尚未成为事实，则用虚拟语气；若谓语动词所表示的动作已经发生，或已经成为事实，则要用陈述语气。比较：He insisted that I had read his letter. 他坚持说我看过他的信。
He insisted that I should read his letter. 他坚持要我看他的信。
▲表示“命令”后的宾语从句

He suggested that we should leave early. 他建议我们早点动身。
注：与动词insist相似，动词suggest后接宾语从句时，除可用虚拟语气外，也可用陈述语气，两者的区别也是：若谓语动词所表示的情况尚未成为事实，则用虚拟语气，此时suggest通常译为“建议”；若谓语动词所表示的情况为既成事实，则要用陈述语气，此时的suggest通常译为“表明”、“认为”。比较并体会：
He suggested that we (should) stay for dinner. 他建议我们留下吃饭。
I suggested that you had a secret understanding with him. 我觉得你与他心照不宣。

11、主语从句中的虚拟语气
在It is necessary，important，strange，natural， advisable, anxious, compulsory, crucial, desirable, eager, essential, fitting, imperative(绝对必要), impossible, improper, obligatory, possible, preferable, probable, recommended, urgent, vital etc. ；it is a pity；It is requested/suggested/desired/proposed等结构后的主语从句中要用虚拟语气，即Should+动词原形或只用动词原形。如：

13、在 lest ，for fear that( 以免) , in case (以防)引导的目的状语从句中的虚拟语气
在 lest ，for fear that( 以免) , in case (以防)从句中用should＋动词原形, should 可以省略.
名词性从句中的虚拟语气
虚拟语气表示一种假设的情况，或一种主观的愿望，即动词所表示的动作或状态并非事实，或不可能实现。英语虚拟语气的形式有下列几种：
If I were you, I would give up drinking immediately.
If you should lose, what would you do?
If I were to see her tomorrow, I would tell her thetruth.
If you went there next time, you would see what I mean.
四、虚拟语气的几种特殊用法
省掉if的条件从句结构：
Had you asked me, I would have told you. (=I f you had asked me,…)
2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示，如：
A true friend would not do such a thing.
(=If he were a true friend, he...)
(=If there were no water,…)
(=If you hadn’t helped me,…)
3. 有时条件从句中的动作和结果从句中的动作发生的时间不一致，如：
If he had followe d the doctor’s advice, he would be quite all right now.
If I were you, I would have gone home.
五、虚拟语气的其他用法
He suggested that they (should ) stop smoking.
上述动词的名词形式出现时，that 引导的从句仍用虚拟语气。
He made a request that they (should ) stop smoking.
如果that 引导的从句所表达的内容是事实，也可用陈述语气。
He insists that he is right.
It is right that you should have done your homework.
I wish I had never stopped teaching. (=I am sorry I stopped teaching.)
I wish they’d let us get some sleep.
注意：wish与hope接宾语从句的区别在于：hope表示一般可以实现的希望，宾语从句用陈述语气。wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。试比较：
（1）We hope they will come,(We don’t know if they can come.)
（2） We wish they could come,(We know they are not coming.)
4、as if, as though, would(had) rather(that)引导的从句须用虚拟语气，如：
He acts as if nothing had happened.
I would rather you didn’t tell him.
5、It’s (high) time that…+动词过去式或should+动词原形，如：
It’s time (that) you ha d a hair cut.
It’s high time (that) we took some action.
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 一、虚拟语气用于非真实条件句 （一）形式 I.动词的语气简介： 语气——表示说话人对说话内容的看法的一种语法范畴。在英语中，可用不同的动词形式表示说话的语气。 ?虚拟语气——与事实相反，表达的是怀疑、忧虑推测、祝愿等。 II.虚拟语气的运用 一、在if条件从句中的运用 （一）表格及注意事项 ?注： ? 1. 目前，虚拟语气的were除了在If I were you 的结构中不能改动外，其他有些情况可以用was。 ? 2. 如果表示否定的意思，多用过去时结构，用should和were to较少。
（二）、虚拟条件句中的省略和倒装 若符合下列条件，可以省略if: ? 1.必须是非真实条件句，并且有时，才可以省略if. ? 2.省略if时，主语与的位置必须相互调换。 例： （1）万一我见到她，我会告诉她的。 If I should meet her, I would tell her. （2）如果我处在你的位置上，我会做得更好。 If I were in your position, I would do it better. （3）如果他们准备了的话，他们应该能成功的。 If they had made preparations, they would have succeeded. (三)含蓄条件句 假设情况不以if条件句表现出来，而是通过某个介词或介词短语，不定式表现出来。如with，without，but，but for，otherwise等。根据句子要表达的事态，选择相应的虚拟语气的形式。 I lost her phone number, otherwise I her up. 我弄丢了她的电话号码，否则我就能打给她了 If I had not lost her phone number… But for your help, I would not have the chance to go to school. 要不是有你的帮助，我不会有机会去学校的。 If you had not helped me… I was away that day, otherwise I ____ the lecture. A.had attended B.would have attended C.would attend D.attended 例:（1）我们在那个小村庄中迷路了，否则昨天我们还能去更多有趣的地方地方。 （2）我本来可以帮你的，但是我太忙了。 二、用在宾语从句中的虚拟语气 （一）在wish引导的宾语从句中，表示未能实现或不可能实现的愿望，用虚拟语气。主句
新概念英语第二册语法总结：虚拟语气 虚拟语气分三种情况来掌握： 1、虚拟条件句。 2、名词性虚拟语气。 3、虚拟语气的其他用语。 一、虚拟条件句： 条件状语从句是非真实情况，在这种情况下要用虚拟语气。 1、条件从句与现在事实不一致，其句型为： If 主语＋过去时，主语＋should(could, would, 或might)＋动词原形，如： If I were you, I would study hard. If it rained, I would not be here now. 2、条件从句与过去事实不一致，句型为： If 主语＋had＋过去分词，主语＋should(could, would, 或might)＋have＋过去分词，如：If the doctor had come last night, the boy would have saved. If I had not studied hard, I would have failed in the exam last term. 3、条件从句与将来事实不一致，句型为： If 主语+should(were to, 过去时)＋do，主语＋should(could...)＋原形do，如： If it should rain tomorrow, we would stay at home. If I were to go to the moon one day, I could see it with my own eyes. If you missed the film to night, you would feel sorry. 注意问题： 1、If条件句中绝对不可出现"would"。 2、根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都是遵守上述句型。 3、在条件句中如果出现were, had, should可省去if，将主语与这些词倒装，例如： Had the doctor come last night, the boy would have saved. Were I to go to the moon one day, I would see it with my own eyes. Should it rain tomorrow, we would stay at home.
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
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. (要不是他的帮助，我们还会在工作呢。
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 在英语文法中有三种语气，即直述式语气(In dicative Mood)、祈使语气(Imperative Mood)和虚拟语气(Subjective Mood)，其中前两种我们早已熟悉了，这里则不多谈了，女口：How beautiful she is!则是直述式语气，而Hurry up! Do n't hurry up则是祈使语气。我们主要来看看虚拟语气的主要用法。虚拟语气主要是用来表达一种无法实现的愿望，一种与事实相反的情况，或者将不可能实现的，或可能性很小的事实，假想为事实予以表述。这样的动词结构称为虚拟语气。它主要有三种形式，即与现在事实相反的假设，与过去事实相反的假设，与将来事实相反的假设。它们具体结构如表8 —7。 虚拟语气的构成 虚拟语气其他习惯用法简表
1语法辨析 In correct: If I was a girl, I would marry you Correct: If I were a girl, I would marry you 表示与现在事实相反的虚拟语气时，if条件句中的be动词一律用were，这句话应译为我要是个女孩，我就嫁给你。实际上不可能是个女孩。 In correct: If I were you I will not worry Correct: If I were you I should n't worry 现在时的虚拟语气主句要用should或would加动词原形，这句话应译为我要是你的话，就没有必要烦恼。要注意这种语态用在这里实际上是想把要讲出的观点表达得婉转些，有礼貌些。 In correct: God forgives you! Correct: God forgive you! 这里的主语God是第三人称单数，之所以动词不加s是因为要表达一种祝愿，即人力所不能及的事情，实际上是forgive前有一助动词should, May 等, 但在口语中将其省略了。如：May you be happy祝你幸福。 In correct: If the weather was nice yesterday, we would have gone to the zoo Correct: If the weather had been nice yesterday we would have gone to the zoo
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.

关于虚拟语气的知识点整理 虚拟语气的重点是： 1．一些常见的虚拟语气的句型或结构。 2．虚拟语气的特殊形式，即用来表示要求、建议、命令、提议、意愿等的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式。 3．主从句表示不同的时间概念、事实或假设情况，从而交错成为复合虚拟语气。 4．含蓄条件句中的虚拟语气的表示愿望的虚拟形式。 上述四个要点往往在完形填空或者阅读理解里面存在，尤其是每年完形填空都至少有一道直接考这方面的知识的题目，而在阅读理解里，我们掌握上述四个重点对于我们理解文章的大意和作者态度很有帮助，了解哪些观点是作者假设的、虚拟的，哪些是真实的，这样对于我们回答关于作者态度观点题很有帮助。 下面我们将主要从上述四个方面来重点论述在考试中应该注意的问题。 一、虚拟语气的常见类型和句型 （1）由wish引起的表示愿望的虚拟语气 A．用wish表示对现在的愿望时，它所引起的宾语从句中谓语动词形式为：过去式（be动词用were）。 B．用wish表示对将来的愿望时，它所引起的宾语从句中谓语动词形式为：would, could, might+ 动词原形。 C．wish用于对过去的事实表示一种不可能实现的愿望时，宾语从句中的谓语动词形式为：had+动词过去分词或could, would + have +动词过去分词。 The picture exhibition bored me to death; I wish I had not gone to it. ---“I let Joe borrow our radio for the afternoon.” ---“That’s all right, but I wish he would buy one of his own.” I wish that he weren’t so lazy. (2)had hoped引起的宾语从句中备用语动词形式为would+动词原形，表示一种过去未实现的愿望或令人失望的事。 His father had hoped that his son would go to business with him, but his son became an artist later. (3)would (had) rather, would as soon, would sooner和would prefer所引起的从句中要求用过去式表示当时或将来的情况，用过去完成时表示过去的情况，表示希望或婉转的责备。例如： I’d rather you posted the letter right away. 我倒希望你把这封信立刻寄出去。 I would prefer he didn’t stay there too long.我倒希望他不要在那儿可得太久。 I would just as soon you had returned the book yesterday.我真希望你昨天把这本书还了。 （4）I t’s (high, about) time that 句型中that从句中要求用虚拟语气形式，即动词要用过去式。 It’s time that something was done about the traffic problem downtown. It is high time that we put an end to this discussion.现在是我们该结束讲座的时候了。 （5）as, 或者whether…or…谓语多用be的原形，引导让步虚拟从句，这种用法通常采用倒装结构：Church as we use the word refers to all religious institutions, be they Christian, Islamivc, Buddhist, Jewish, and so on. The business of each day, be it selling goods or shipping them, went quite smoothly. （6）由连接词in case, so that ,unless, lest ,for fear that引起的状语从句中，谓语动词要用虚拟形式，即should(might, would)+动词原形，例如： She put a blanket over the baby for fear that he should catch cold. 她在那个婴儿身上盖上了毯子以免他着凉。 The bad man was put in the soft-padded cell lest he injure himself. (7) if it were not for…与现在事实相反，if it had not been for与过去事实相反，两个都相当于but for： If it had not been for his help(=but for his help),we would not have succeeded.

虚拟语气用法归纳 英语的动词一般可带有三种不同的语气:陈述语气,祈使语气和虚拟语气。不同的语气用动词的不同形式（有的还借助句法形式）来表示。 一、虚拟条件句 条件句有两类:一类是真实条件句，一类是虚拟条件句 如果假设的情况是有可能发生的,就是真实条件句，谓语用陈述语气。 Ｉf yｏu doｎ’tｗork hard, you will faｉｌ． If it iｓfine tomorrｏw, wｅｗill go foｒａpicnic． 如果假设的情况过去、现在、将来都不存在,则为虚拟语气 虚拟条件句和对应主句的动词形式列表： １.与现在事实相反的虚拟 What woｕｌd yｏｕdo if you won the lottery? If I weｒe you, Ｉwoulｄsｅize tｈe chance to goａbｒoad. If Ｉhaｄａlot of ｍoｎｅy now, I ｗｏｕｌd travｅl arounｄtｈe worlｄ. 2．与过去事实相反的虚拟 If you haｄbeen ｈere ｙesｔerｄay,ｙou wouｌｄｈavｅseen her. Iｆheｈaｄｄriven mｏre cａｒefｕlly,ｈｅwoｕｌｄnｏt haｖe had the ca ｒacciｄenｔｙestｅｒday. 3. 与将来事实相反的虚拟 Ｉf it weｒe to rａin/should rａin/ｒainｅd tomｏrroｗ，our pｌan woｕld ｂe put ｏff． If we weｒｅto picnic，ｗe ｗｏuld not be ａble to hｅlp. 二、错综、混合虚拟语气 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。 １.IｆI hａd ｓeeｎyou, I ｗoulｄnｏｔbｅsｏworｒｉed now．(从句是对过去的假设，主句是对现在的假设) 2.If youｈａｄnot ｗatcｈed telｅvｉｓion so laｔe laｓｔｎight, you woｕld not beｓo sleepy ｎow.( 从句是对过去的假设，主句是对现在的假设） 3．Hａｄｙｏu ｆollｏwed ｔｈe ｄoｃｔor’s sugｇeｓtion, you wouｌd bｅfine now.(从句是对过去的假设,主句是对现在的假设) 4．If I hａd ｍade somｅmoｎey lastｓummer, I ｗould go on hｏｌiday nexｔmonth.( 从句是对过去的假设,主句是对将来的假设)
Unit 3 Understanding each other 虚拟语气（1） 概念引入 动词的语气表示说话人的态度和看法，可分为陈述语气、祈使语气和虚拟语气。 1. 陈述语气用来陈述事实或可能发生的事，有肯定、否定、疑问和感叹等形式。 Aileen showed great concern about you. 艾琳很为你担心。（肯定） My legs were so weak that I could hardly stand. 我的腿软得简直不能站立。（否定） Would you care to come and stay with me over the weekend? （疑问） 你愿意来和我过周末吗？ 2. 祈使语气用来提出请求、发出命令、警告、威胁、叮嘱、祝福、建议等。 Enjoy yourselves with your trip. 一路愉快。（叮嘱） Don’t let this type of things happen again. 别让这种事再次发生。（警告） 3. 虚拟语气是说话人为表达一种假设, 或一种主观愿望, 即认为动词所表示的动作或 状态并非真实或仅是主观设想时所用的动词形式。 我们先看这些含虚拟语气的句子： 1. If you were an artist, what kind of pictures would you paint? 2. If you could have three of these paintings on the walls of your classroom, which would you choose? 3. If the rules of perspective had not been discovered, no one would have been able to paint such realistic pictures. 4. Without the new paints and new technique, we would not be able to see the many great masterpieces for which this period is famous. 5. Have you ever wished you could paint as well as a professional artist? 本单元将重点学习if从句的虚拟语气和wish和“suggest” 类后的宾语从句中的虚拟语气 的用法。 用法讲解 if引导的虚拟条件句 1. 真实条件句与虚拟条件句： 条件句分成两种，一种是真实条件句，一种是非真实条件句。真实条件句用陈述语气， 所做的假设，说话人认为是可以实现的，或者与事实相符的；而使用虚拟条件句时，说话人 知道所做假设与事实不符，或者很可能无法实现的。如： If I have enough money, I will go to the zoo with you. 如果我有足够的钱，我会和你一起去动物园。（暗含“我看看钱是否够，如果够我就去”）If I had enough money, I would go to the zoo with you. 如果我有足够的钱，我会和你一起去动物园。 （暗含“我事实上没有足够的钱，没法和你去”） 2. 虚拟条件句的构成： 假设类型条件从句（if从句）谓语动词主句的谓语动词 与现在事实相反一般过去式(be用were) would/should/might/could +动词原形 与将来事实可能相反1）一般过去式(be只用were) 2）were to + 动词原形 3）should + 动词原形 would/should/might/could+动词原形 与过去事实相反had done would/should/might/could + have+过去分词
虚拟语气语法归纳 虚拟语气的使用主要体现在三个方面：虚拟条件句、虚拟语气在某些从句中的运用，以及虚拟语气的一些特殊用法。虚拟条件句虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性 极小。根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句及与将来事实相反的虚拟条件句。具体情况请看下表： 例句： 1. 表示与现在事实相反 If I had enough money now I would lend it to you. If I were you I would go to tell him the real feeling upon him. If I were a boy, I would join the army. If the had time, she should go with you. 2. 表示与过去事实相反 If he had taken your advice he wouldn't have made such a bad mistake. She would have come to enjoy the party if she hadn't been very busy. If he had taken my advice, he would have succeeded in the competition. 3. 表示与将来事实相反 I would go shopping with you if it were to be Sunday tomorrow. If he were to be given another chance to do it again he could certainly achieve more. If it were to rain tomorrow, the football match would be put off. 1. 虚拟条件句的倒装
