Grammar in use-虚拟语气
语气是表示说话者对动词所表示的动作或状态的态度的一种动词形式。英语中有三种语气：直陈语气、祈使语气和虚拟语气。虚拟语气是表示说话人一种主观愿望、假想或建议。
一、真实条件和非真实条件
英语中的条件句分为真实条件和非真实条件。真实条件表示现实情况中可能实现的情况，而非真实条件表示与现实情况相反的假想情况。
（真实条件）如果工作条件不太差，我会接受这项工作。
If the working conditions are not too bad, I will accept the job.
（非真实条件）如果工作条件不太差，我就接受这项工作了。
If the working conditions were not too bad, I would accept the job.
（事实是The working conditions are too bad, so I won't accept the job.）
（真实条件）他说他如果失败，他还会再试一次。
He said if he failed, he would have another try.
（非真实条件）如果他失败的话，他会再试一次的。
If he had failed, he would have had another try.
（事实是He didn't fail and he didn't have another try.）
二、非真实条件句
1.与现在事实相反
If从句：动词过去时（be动词用were，但在口语中，在单数第一、三人称后也有用was。）
主句：would/should/could/might + 原形动词
如果房间大一点的话，我们就在那儿举行聚会了。
If the room were larger, we would hold the party there.
假如我身边有钱，我就借点给你。
If I had money on me, I would lend you some.
2.与过去事实相反
If从句：had + 过去分词
主句：would/should/could/might have + 过去分词
如果那个地方不远的话，我们就步行去那儿了。
If the place had not been far away, we would have walked there.
如果你仔细一点，这个错误是可以避免的。
If you had been more careful, the mistake might have been avoided.
3.与将来事实相反
If从句：should/were to/was to + 原形动词
主句：would/should/could/might + 原形动词
如果明天天气好，我们就继续收割庄稼。
If it should be fine tomorrow, we would go on with our harvest.
如果我们有足够的时间，我们可以讨论那个问题。
If we were to have enough time, we could discuss the matter.
有时if从句和主句所表示的假想情况时间不一致，如从句表示与现在事实相反，而主句表示与过去事实相反，那么句子两部分的动词形式也可以作相应的调整。
如果你身体好，我当时就让你接受那项工作了。
If you were in good health, I would have let you take that job then.
如果他早点出发，他现在已经到家了。
If he had set our earlier, he would be home now.
三、含蓄条件句
有时非真实条件句中并不出现if从句，假想的条件隐含在情景中或者其他语法手段表示，这种情况称为含蓄条件。含蓄条件一般可以用如下的语法手段表示：
任何人处于我的地位不会对这个想法产生兴趣。（非谓语形式）
Anyone being in my place wouldn't be interested in the idea.
聪明一点的人不会干那种事。（形容词比较级形式）
A cleverer man wouldn't have done that kind of thing.
我们在3天里完成了本来应该花6天完成的工作。（定语从句）
We finished the job which would have taken six days to finish in three days.
要不是机组人员，飞机就坠毁了。（介词词组= If it had not been for the crew, ...）
But for the crew, the plane would have crashed.
他不可能写信给我，否则我现在就收到他的信了。（上下文情景）
He can't have written to me. Otherwise I would have got his letter by now.
四、非真实条件句的倒装形式
非真实条件句if从句中若含有助动词should, had或者were，那么可以与主语倒装，但动词过去式不可以与主语倒装。
如果他在这里，他就会来帮助我们。
Were he here ( = If he were here ), he would come to help us.
Attention: 倒装结构中不能用was。
如果他吃过午饭，他不会吃那么多小甜饼。
Had he had lunch ( = If he had had lunch ), he would not have eaten so many cookies.
万一明天下雪，我们就推迟旅行。
Should it snow tomorrow ( = If it should snow tomorrow ), we would put off our trip.
某些动词后接宾语从句中的虚拟语气
Suggest, insist, demand等动词
Suggest, insist, demand, propose, require, ask, advise, order, request等动词后面的宾语从句中谓语动词须用虚拟语气，即（should）+ 原形动词。
将军命令他的部队开往前线。
The general ordered that his troops (should) move on to the front.
他们要求参观者在车间不吸烟。
They require that visitors (should) not smoke in the workshop.

It is suggested that everyone (should) give a five-minute talk at the party.
他建议我们一路爬到山顶。
His suggestion is that we (should) climb all the way to the top of the hill.
He made the suggestion that we (should) climb all the way to the top of the hill.
Attention: 但是当suggest作“暗示，表明，使人联想起”时，以及insist作“坚持认为”时，后接宾语从句仍用直陈语气。
他建议我们为学生开设更多的课程。
He suggested that we (should) offer more courses to the students.

我坚持要那个孩子在玩饭前洗手。
I insisted that the boy (should) wash his hands before having supper.
我坚持说那天早晨我乘的是早班火车。
I insisted that I had taken the early train that morning.
?Wish
?Wish后接that宾语从句表示一种假象的情况，实现的可能性不大。宾语从句中谓语动词须用虚拟语气，有三种情况。
?如果假想的情况与主句的愿望同时发生，则从句谓语动词用过去时，be动词用were/was。
?我年轻10岁就好了。
?I wish I were/was ten years younger.

?If only he had a sense of humor.

高中英语语法虚拟语气教学设计
高中英语语法虚拟语气 教学设计 集团档案编码：[YTTR-YTPT28-YTNTL98-UYTYNN08]
高中英语语法虚拟语气教学：The subjunctive mood 厦门第十中学吕瑞珠 一、概述 本节课是高中英语语法教学课，授课内容为虚拟语气，授课对象是高三年学生。从呈现、加深记忆、巩固到实践并将语言项目运用于写作中并做适当的点评，大概需要两课时。但我这里着重阐述的是第一课时的教学内容、教学策略等。 通过本节语法教学课的学习，学生重新整合自己的有关虚拟语气的知识，复习已知的虚拟语气的表达形式如：I wish I could fly freely in the sky like a bird; It is high that you got up.等等，并学习新的表达形式如：The English teacher suggested that we should read the English newspaper every day; I would have passed the English exam if I had worker harder in the past 20 days.最为重要的是，学生在学习完虚拟语气的表达形式后，要在写作中运用。 虚拟语气在高中英语语法的难点之一，多数学生感到费解，因此也更需要老师的指导与相应的实践与运用，并且较好地掌握虚拟语气的表达形式，有助于扫除学生阅读过程中对个别句子的理解。 二、教学目标分析 1．知识与技能 1）复习学生已掌握的虚拟语气表达的句型： I wish I were… / I could … It is high time that you did your homework.. If I were you, I would… 2) 学习虚拟语气新的表达方式，尤其是if引导的虚拟条件状语从句，掌握与现在事实、与过去事实、与将来事实相反的三种虚拟语气的表达，特别是主句与从句时态的呈现；还有引导出的宾语从句需要运用虚拟语气的动词，如suggest, insist, propose, demand and so on. 3）培养学生运用所学知识表达自己的思想的能力。 2．过程与方法 1）引导学生在欣赏英文歌曲An Angel的情景教学过程中，开启对虚拟语气表达已有的知识记忆。
高考虚拟语气用法详解()
高考虚拟语气用法详解 一·语气概述 和时态语态一样，语气也是谓语动词的一种形式，它表明说话者的目的和意图。英语中有三种语气：陈述语气，祈使语气和虚拟语气。（有的语法书说语气有四种，即还包括疑问语气）。 eg：①He doesn’t see very well in his right eye .他右眼视力不太好。（陈述语气） ②Have they ever been to Australia ?他们去过澳大利亚没有？（疑问语气） ③Please read through the instruction in advance .请先通读说明书。（祈使语 气） 二·虚拟语气概述 在英语中，由于说话人的意图不同，动词需用不同的形式，称为语气。虚拟语气是指说话人表示一种假设的情况，一种愿望，怀疑，推测，请求等，即认为动词所表示的动作或状态并非事实。虚拟语气可用于状语从句，名词性从句，定语从句及其他结构中。 三·非真实条件句中的虚拟语气 真实条件句（遵循主将从现原则） A.由If引导的两种条件句： 非真实条件句（虚拟语气） 以下为If在非真实条件句中虚拟语气的形式和用法： 假设类型If从句主句 与现在事实相反did (be用were)should/would/ could/might do 与过去事实相反had done should/would/ could/might have done 与将来事实相反1)did 2)were to do 3)should do should/would/ could/might do eg：①If I were you ,I would reconsider their advice .如果我是你的话，我会重新考虑他们的意见。（与现在事实相反） ②You would not have caught a cold if you had put on more clothes .如果你多穿了些衣服，你就不会得感冒了。（与过去事实相反）
高中英语情态动词与虚拟语气
情态动词与虚拟语气 【语法要点】 情态动词 所谓情态动词是指它含有一定的含义，可以表达某种感情和说话的语气，但是它不可以单独使用作谓语动词。学习情态动词主要学习英语国家的语言习惯和表达法，特别是在口语中不要过分追求原理，更不要不根据说话场合而进行推理，编造出一些语法结构正确的中文式英语。 一、情态动词的类型 1.只作情态动词的有：must、can、could、may、might、ought to 2.既可作情态动词又可作实义动词的有：need、dare 3.既可作情态动词又可作助动词的有：shall、should、will、would 二、情态动词的特征 1.表示说话人的情感态度，不能单独作谓语，与行为动词或连系动词一起作谓语。 2.情态动词没有人称和数的变化，后接动词原形。 3.具有助动词的特征：可用来构成否定句、疑问句或简短答语。 三、情态动词的用法 1.表示能力 （1）表示现在的能力，用can或be able to。表示一般的能力时多用can，表示“经过努力成功的做成某事”用be able to。 （2）表示过去的能力，用could或was/were be able to。区别同上。 （3）表示将来的能力，用will be able to。 2.表示推测、可能性 （1）can用在肯定句中表示客观的可能性，而不表示具体事情实际发生的可能性。 例如：Accidents can happy on such rainy days. （2）表示具体事情实际发生的可能性的情态动词，其表示可能性的层次如下表： 情态动词肯定式否定式疑问式 must 必定、必然、一定 will 很可能、大概不会、不该会……吗？ would 可能性较will小不会、不该（较won’t弱）会……吗？（较will弱） should 应该会、理应（表示合乎理想的情况或结果） ought to 与should同义 can 一定不会、不可能（否定推测）有可能吗？ could 可疑的可能不可能（与can’t同义）有可能吗？（较can弱）may 或许、可能、说不定可能不 might 或许、可能（较may弱）可能不（较may not弱） 注意→（1）may，must常用于肯定句，一般不用于否定句和疑问句。 （2）can常用于否定句，疑问句和感叹句中，表示疑惑、惊讶或不相信等意思。could既可用于肯定句，又可用于否定句、疑问句中。
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．。
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）

高考英语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. 6.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， 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：

高考英语二轮专题总复习 语法部分虚拟语气
2012届高考英语二轮专题总复习语法部分虚拟语气 表示说话人所说的话不是事实，而是一种假设、愿望、怀疑或推测。 虚拟语气在if条件从句中的使用 【观察】 If I were you, I would go to bed early tonight. 如果我是你，我今晚就会早点睡。If you took the bus, you would be late for the film. 如果你坐公车去看电影，那么你就会迟到。 If Jack had scored that goal, we would have won the football match. 如果杰克射进了那个球，我们就会赢得那场足球比赛。 If she hadn’t come, I might have been in trouble. 如果她没来，我可能已陷入困境了。 I could help you if you had difficulty in doing your homework. 如果你做作业有困难，我会帮助你的。 If it were to rain tomorrow, they would not go out. 如果明天下雨的话，他们就不会出去。 【归纳】 注意：若从句中的谓语动词是be动词的话，一律用were。 【实践】 1.If he my advice, he wouldn’t have lost his job. A. followed B. should follow C. had followed D. would follow 2. 翻译：如果我有足够的钱，我会周游世界。 If I had enough money, I would travel around the world. 翻译：如果明天见到他，我会邀请他到我家。 If I should see / were to see / saw him tomorrow, I would invite him to my house. 虚拟语气用于条件状语从句时，可以转换成下列形式： （1）省略if, 用“were, had, should + 主语”。如： Were she my daughter, I wouldn’t allow her to study abroad. 如果她是我女儿，我就不让她出国学习了。 Had I worked hard, I would have surely succeeded. 如果我当时努力学习的话，我肯定会成功的。 Should there be a meeting tomorrow, I would come. 如果明天有会议，我会来。 （2）含蓄条件句。虚拟语气句中不出现if 条件句，而是用介词、介词短语或连词通过上下文表现出来，这时须根据句子的含义判定是用虚拟现在式还是虚拟过去式。常见短语有：but for, without, otherwise, or 等。如：
大学英语语法-虚拟语气
虚拟语气 1. I wish (that可省略,下同)I knew the answer to the question.我希望知道这个答案。(事实上是不知道) 2. He wishes he hadn't lost the chance. 他真希望没有失去机会。(其实已失去) 3. You wished she would arrive the next day.(would + arrive) 你希望她第二天会到。(事实上她还没到) Subjunctive Mood作为专门表达假设意义和其他非事实意义的动词形式，仅是古英语遗留下来的残余。它仅有两个形式，即be型虚拟式和were型虚拟式。 Be型虚拟]----- be型虚拟式是以动词原形表示的，不管主语是什么人称，动词一律用原形，如动词为被动态，则助动词be也用原形。其主要用法如下： 1)用于表命令、决定、建议、坚持等词语之后的that分句中 这一用法又分三种情况： a)用在 decide,decree,demand,insist,move,order,prefer,propose,recommend,request,require, suggest,vote等动词之后的that分句中.（宾语从句） 在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇，怀疑，不满等。 He ordered that all the books be sent at once. He ordered that all the books be sent at once. we propose that somebody neutral take the chair. She insisted that she go to the south for her holiday. b)用在 advisable,appropriate,desirable,essential,fitting,imperative,important,impossible,nece ssary,obligatory,proper等形容词之后的that分句中。（主语从句） It is essential that all the facts be examined first. It was appropriate that thisi tax be abolished. I thousht it advisable that an armed guard stand in readiness. c)用在 decision,decree,demand,instruction,order,requirement,resolution等名词之后的that分句中。 The board has given instructions that the agent fly to Boston. We were faced with the demand that this tax be abolished. Their decision was that the school remain closed. 在这一用法中be型虚拟式能与“should+不定式”交替使用，也能与to-不定式交替使用。 He ordered that the books be sent at once . = He ordered that the books should be sent at onc. = He ordered that the books to be sent at once. 2）用于由if,though等引导的分句中.
高中英语语法-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。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?

高考英语中虚拟语气的用法—难点突破 对虚拟语气的测试主要涉及以下方面： 1）主语、表语、同位语、宾语从句中虚拟语气的用法 2）wish , would rather虚拟语气结构的用法 3）if 条件句中虚拟语气的用法，应特别注意省略if 的倒装结构是考试的重点 4）if only 结构中虚拟语气的用法 5）but for , or, otherwise 等含蓄条件句的用法 6）It’s time (that) 等结构中虚拟语气的用法 （一）虚拟语气在虚拟条件句中的运用 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 you had come yesterday, you would have met that famous professor.如果你昨天来，你就会见到那位著名的教授了。（隐含的事实是：你昨天没来，也没见到那位著名教授）。 在含有虚拟条件句的复合句中，主从句的谓语都要用虚拟语气，现将其形式列表如下：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，她就会帮我了。（事实上她没有时间） 2. 表示与过去事实相反的假设和结果。 If you had taken my advice, you wouldn’t(couldn’t) have failed in the exam. 如果你听了我的建议，你就不会考试不及格。（事实上你根本没听我的。） 3.表示与将来事实可能相反的假设和结果
虚拟语气用法总结讲课稿
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,

A. being B. are C. be D. were 2) If I _____ the meaning of the word, I wouldn't have to look it up. A. know B. knew C. known D. knowing 2. 虚拟过去时是表示与过去事实相反的假设，if 从句的谓语形式用过去完成时即had＋过去分词，主句用would / should / could / might + have +过去分词。 例：1995年6月四级第46题 We didn't know his telephone number, otherwise we _____ him, A) would have telephoned B) must have telephoned C) would telephone D) had telephoned 3. 虚拟将来时是表示对将来实现的可能性很小的或不确定的假设。If从句的谓语形式用一般过去式或用were to / should +动词原形，主句用would / should /could/ might +动词原形。 2
