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。
eg：
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）
用法及动词形式
1、表示与现在事实相反的情况：
从句：主语+过去时
主句：主语+should/would/could/might+do
例：
1.If I were you, I would take an umbrella.
如果我是你，我会带把伞。（事实：我不可能是你）
2.If I knew his telephone number, I would tell you.
如果我知道他的电话号码，我就会告诉你。（事实：不知道）
3.If there were no air or water, there would be no living things on the earth.
如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水)
4.If I had any money with me, I could lend you some.
如果我带钱了，我就会借给你些。（事实：没带钱）
5.If he studied harder, he might pass the exam.
如果他再努力些，就能通过考试了。（事实：没有努力）
2、表示与过去事实相反的情况
从句：主语+had done
主句：主语+should/would/could/might+have done
例：
1. If I had gotten 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）
2.If he had taken my advice, he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。
（事实：没有听我的话）
3、表示对将来情况的主观推测
从句：①if+主语+were to do 主句：①主语
+should/would/could/might+do
②if+主语+di d/were ②主语+should/would/could/might+do
③if+主语+should+do ③主语+should/would/could/might+do
例：
1.If he should come here tomorrow, I should/would talk to him.
如果他哪天来这儿的话，我就跟他谈谈。（事实：来的可能性很小）
2.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。（事实：不知能否下雪）
3.If she were to be there 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。
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。
如：
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，即将were, should, had等词置于句首，这种多用于书面语。
如：
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。
6、非真实条件句中的条件从句有时不表达出来，只暗含在副词、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，在多数情况下，条件会暗含在短语中，如without…., but for….等
如：
But for his help, we would be working now.
要不是他的帮助，我们还会在工作呢。
Without your instruction, I would not have made such great progress.
要是没有你的指导，我不会取得如此大的进步。
We didn’t know his telephone number; otherwise we would have telephoned him.
我们不知道他的电话号码，否则我们就会给他打电话。
7、有时，虚拟条件句中，主、从句可以省略其中的一个，来表示说话人的一种强烈的感情。
①省略从句
He would have finished it. 他本该完成了。
You could have passed this exam. 你应该能通过这次考试了。
②省略主句
If I were at home now. 要是我现在在家里该多好啊。
If only I had got it. 要是我得到它了该多好啊。、
编辑本段虚拟语气（Subjunctive Mood)的其他用法

He suggested that we (should) take the teacher’s advice.
He insisted that we (should) take the teacher’s advice.
He demand that we (should) take the teacher’s advice.
He ordered that we (should) take the teacher’s advice.
insist如果翻译成坚持某种动作才用虚拟语气；翻译成坚持某种观点就不用虚拟语气。

他坚持说他是个学生。
这个语句表示的是事实，因此在这个语句中不能使用虚拟语气。
suggest意为“建议”才用虚拟语气，意为“暗示”则不用虚拟语气。
如：His face suggests that he looks worried .
他的表情暗含着他很担心。
这个句子本身是事实，因此它就没有用到虚拟语气。
2、表情绪.观点的形容词或名词也要用虚拟语气.如:necessary、important、impossible、natural、strange、surprising、funny、right、wrong、better、a pity等。
句型：It is.......that +主语从句，从句的谓语动词都要用should+原型或只用动词原型。
3、在even if, even though 所引导的让步状语从句中，可用虚拟
语气，主句、从句的结构与if所引导的条件从句结构相同。如：Even if he were here himself, he should not know what to do.

8、虚拟语气在方式状语从句的应用。详见百度百科之方式状语从句词条。
编辑本段四、省略的虚拟条件句型
省略连词if
有时可将条件从句的连词if省略，但此时应用倒装句型，即将从句中的were, should, had 等提到句首：
Were I Tom, I would refuse. 如果我是汤姆，我会拒绝。
I will go, should it be necessary. 假若有必要，我会去的。
Had it not been for the bad weather we would have arrived in time. 若不是天气坏，我们就准时到达了。
【注】
① 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。
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…)
省略条件句的主语和其后的动词be
若主从句主语一致，且谓语部分包含有动词be，通常可将主语和动词be省略：
If repaired earlier, the tractor would not have broken down.
要是早点儿修一下，拖拉机就不会抛锚了。(=If it had been repaired earlier…)
省略“it+be”
If necessary, I would send more farm-hands to help you.
如果需要的话我会派更多的民工去帮你。(=If it was necessary, I would…)
省略整个条件从句
这样的省略通常需要借助一定的上下文，即省略条件从句后，所剩下的主句的意思在一定的上下文中意思是清楚的：
I might see her personally. It would be better. 我可以亲自去看她，这样好一些。(=…If I saw her personally, it would be better.)
编辑本段在含蓄条件句中的用法
(1) 条件暗含在短语中。如：
We didn’t know his telephone number; otherwise we would have telephoned him.
我们不知道他的电话号码，否则我们就会给他打电话。（暗含条件是otherwise）
Without your help, we wouldn’t have achieved so much.
没有你的帮助，我们不可能取得这么大的成绩。
（暗含条件是介词短语without your help）
But for your help, I would not have succeeded in the experiment.
如果没有你的帮助，我的实验就不会成功。（暗含条件是but for your help）
It would cause great trouble not to lubricate the bearing immediately.
不立即润滑轴承就会引起很大的故障。
（暗含条件是not to lubricate the bearing immediately）
(2) 条件暗含在上下文中。如：
I would not have done it that way.
我是不会那么做的。（可能暗含if I were you）
I was busy that day. Otherwise I would have come to help you.
我那天很忙。否则我会来帮你的。（可能暗含if I hadn’t been so busy.）
You might come to join us in the discussion.
你可以参加我们的讨论。（可能暗含if you wanted to）
I would have bought the DVD player.
我是会买下那台影碟机的。（可能暗含if I had the money）
But for the storm, we should have arrived earlier.
要不是碰到暴雨，我们还会早些到。（可能暗含if it had not been for the storm）。
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。 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2
虚拟语气 1．虚拟语气在条件句中的应用 e.g. He would be alive today if the doctor had come sooner last night. If it were not for… / If it had not been for… = but for 3) 特殊结构的条件句but for without (with no) e.g. If it were not for his, help, I could never go to college. e.g. But for air and water, nothing could live. e.g. Without electricity, there would be no modern industry. 4) 条件句的省略 a.省if，用倒装，限于谓动为were, had, should e.g. Were I you, is shouldn’t so it like that. Had you not helped me, I should have failed. 如果没有你的帮助我就失败了。 b.省主句的虚拟结构（表愿望） e.g. If only I could help you! 如果我能帮助你就好了。 If only I had more money! 要是我有更多的钱就好了。 If only you had not told him what I said! 要是你没有把我的话告诉他就好了。 2. 虚拟语气在主语从句中的应用 1）It is + adj. + that …+ (should) v.: 表愿望，要求，建议等 necessary, important, essential, imperative, natural, impossible, strange, vital, obligatory, resolved, desirable, advisable, preferable, urgent, etc. e.g. It is strange that she (should) have left with the light still on. 2) It is + p.p. + that…+ (should) v.: 表愿望，要求，建议等 suggested, required, demanded, urged, ordered, desired, advised requested, urged, proposed, recommended, etc. e.g. it is suggested that the automobile be oiled every day. 3) It is (high / about) time + (that)…+ 一般过去式（be →were） e.g. It is high time that we were off to London. 3. 虚拟语气在宾语从句中的应用 1) suggest, require, order, demand, propose, advise, insist, maintain, recommend, urge, prefer, request, command, desire, ask, object, direct, pray, propose等后的宾从宾从谓动(should) v. 2) wish后的宾从 a. 表无能为力的过去愿望 sb. wish + (that)…+ had ved. / could (would, might) have ved.
虚拟语气用法详解 (1)
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 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) 非真实条件句中的虚拟语气根据不同的时间有三种不同的形式。 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：wo uld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) ②条件从句的谓语动词为be时，不管其主语为单数还是复数通常都用were，但在口语或非正式文体中的单数第一人称和第三人称后，也可用was，不过在If I were you这样的表达中，通常还是以用were为宜。 ③有时条件从句用would表示愿意： If he would live on with me, I would be his better half. 要是他还愿意跟我过，我仍会做他的妻子。
高中英语 第二册 语法总结 虚拟语气
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.
英语虚拟语气语法归纳总结
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(二)

高三年级英语语法-虚拟语气全总结
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。否定句时not留在原来位置不变。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)
虚拟语气用法归纳 (2)
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.

高中英语语法(虚拟语气)
Unit13虚拟语气专题讲解 【知识要点】 语气（mood）是一种动词形式，用以表示说话者的意图或态度。 英语有三种语气： ＊直陈语气（indicative mood）---- 事实 France lies to the east of England. ＊祈使语气（imperative mood）---- 请求、命令 Make yourself at home. ＊虚拟语气（subjunctive mood） If there were no air and water , we should not be able to live on the earth. 虚拟语气表示说话人的一种主观愿望或假想，所说的是一个条件而不一定是事实，或与事实相反。 一. 虚拟语气在if条件状语从句中的用法 假设类型条件从句谓语 动词形式 主语谓语 动词形式 与现在事实相反动词的过去式(be用were而不用was) should/ would /could/ might+动词原形 与过去事实相反had + 过去分词 should/ would/could /might + have+过去分词 与将来事实相反1.should+动词原形 2.动词过去式 3.were to+动词原形 should/ would/ could/ might +动词原形 1. 在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 1）If I were you，I wouldn't have missed the film last night． 2）If he had followed the doctor's advice，he would recover already．（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should 移到句 首构成非真实条件从句的另一种句型，其意思不变。 1）Had we time to spare，we would be glad to go to the park． 2）Were it not for the discovery of electricity，the modern world would experience great inconvenience． 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词 （如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。 1）But for your advice，I would not be able to do this work． 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．。
关于虚拟语气的知识点整理
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(2)
虚拟语气(2) 虚拟语气是用来表示与事实相反或不大可能实现的情况。主要是通过动词的变化来体现的。 ▲在某些主语从句和条件状语从句中虚拟的用法 在It is important, impossible, strange, vital 至关重要的, natural, essential必需的；基本的, desirable值得要的, preferable更好的, advisable可取的, appropriate适当的, surprising, sad,urgent, suggested, necessary, requested, ordered,+that…句型中，主语从句在英国英语中用should +原形动词。在美国英语中省略should直接用原形。 在for fear that（以防……起见）引导的条件句中用法同上。 在unless, when, so(as) long as，suppose, in case, on condition lest(以免)引导的条件状语从句中也可用虚拟语气，用法同上。 ●It is necessary that he（should）come on time to attend the meeting. 他按时来出席会议是必要的。 ●It is natural that he（should）love Merry. 他爱玛丽是很自然的事。 ●He took an umbrella for fear that it (should) rain. 他带了一把伞，以防天下雨。
●As long a s my wife (should) get ready, we will go. 只要我太太准备好了，我们就去。 ▲在suggest, propose, demand, inquire, request, desire想望, 期望, insist, order, advise, agree等表示建议、要求、命令的动词后的宾语从句中。英国英语用should +原形动词，美国英语省略“should”用原形动词 ●He insisted that we（should）get there on time. 他坚持我们要按时到那。 ●The dean proposed that the question（should）not be discussed at once. 系主任提议这个问题不要马上讨论。 ▲在think, expect, believe, 是否定形式时，宾语从句可用虚拟语气：should +动词原形，should不可省。 ●She said she never expected I should lend money to her. ▲suggestion, proposal, request, advice, order, command等表示建议、命令、要求等的名词后面的表语从句中，用should+动词原形，表示虚拟，should常常省略。 The general’s command was that the soldiers (should) leave their fort and carry out more important tasks. ▲were (was) to 有时在虚拟条件句中用were (was)表示试探的口气。 ●If you were (was) to do something like that I would not

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.
