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．。
虚拟语气 一．语气的分类： 二．虚拟语气的用法： （一）虚拟语气在if条件句中的用法： ---If I were you, I would give it up. (与现在事实相反) ---If I had taken his advice, I would not have made such a mistake. (与过去事实相反) ---If she came/should come/were to come, I could ask her for help. (与将来事实相反) 2．特殊用法： ①错综时间虚拟条件句：条件从句与主句所指时间不一致，主从句的谓语动词要根据假设的时间来定。 ---If you had followed the doctor’s advice, you would be much better now. ②if条件句虚拟倒装：可以把if从句中的should, were, had置于句首，省略if构成倒装。 ---Were I you, I would give it up. ---Had I taken his advice, I would not have made such a mistake. ---Should she come, I could ask her for help. ③含蓄虚拟条件句：有时假设的情况并不以if引导的条件从句表示出来，而是通过一个介词短语或其他方式表示。常用的词或短语有：without, but for, otherwise, or, but等。 ---Without/But for your help, I could not have succeeded. ---I should have returned the book last week, but I was too busy. （but后为真实情况） ---He was ill, otherwise/or he would have helped us. （otherwise/or前为真实情况） ④特殊的if句虚拟：If it were (had been) not for…“要不是…” ---If it were not for peace, we could not be living a happy life. ---If it had not been for your help, I would have failed. （二）虚拟语气在名词性从句中的用法： 1．一些表示坚持，命令，建议，要求的词用于名词性从句中时从句的谓语动词用虚拟（一坚持，二命令，三建议，四要求） ---Our teacher suggested that we (should) study hard. (宾语从句) ---That we (should) study hard was our teacher’s suggestion. (主语从句) ---It was suggested that we (should) study hard. (主语从句) ---Our teacher’s suggestion was that we (should) study hard. (表语从句) ---Our teacher gave us a suggestion that we (should) study hard. (同位语从句) ★suggest表示“暗示”，insist表示“坚持说”时不用虚拟。 ---His pale face suggested that he was ill. ---The old man insisted that I had stolen his money.
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.

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：
考研英语语法虚拟语气解析（一） 虚拟语气是谓语动词的一种形式，用来表示假设，或用来表示命令、建议以及说话人的主 观愿望，有时也可以使语气缓和、委婉。虚拟语气作为一重点语法，在各类考试中占有相当 大的分值，所以理解该语法，不管对于考试，还是在日常应用中都有相当大的作用，本节将 就考试重点作详细讲解。 一、虚拟语气的用法 常用于条件句中，表示与现在、将来、过去相反的假设，表示与现在、将来、过去相反假设时，主句与从句谓语动词的变化形式，现以动词do为例说明。 主句从句现在would/should/could/might + do be 宀were/do 宀did 将来 would/should/could/might + do were to + do/should + do （只能用should）过去 would/should/could/have done had done注：有些语法书中在"与将来相反假设”的条件从句中也有do i did，这样就和“与现在相反假设”的主句、从句完全相似，其主要区别在于各自的时间状语上，另外如果在“与将来相反假设”的条件从句中出现should+ do，那么主句 中就避免使用should+do，可以用would/could/might+do。 例句：If you were to exam ine the birth certificates of every soccer player in 2006 s World Cup tour name nt, you would most likely find a no teworthy quirk. （选自2007 年Text 1） 分析：该句是复合句。 译文：假如你去调查2006年世界杯上每位足球运动员的出生证明，你很可能会发现一 个值得注意的现象。 例句：If that happe ned, passi on ate con sumers would try to persuade others to boycott products, putting the reputation of the target company at risk.（选自2011 年Text 3）分析：该句是复合句，表示与现在相反的假设。其中，分词短语putting the reputation of the target company at risk在句中作状语，表示结果。 译文：这种情况一旦发生，充满激情的消费者会尽力说服他人抵制产品，从而使目标企业的声誉处于危 险境地。 例句：Everything here would have been destroyed utterly , if his wife hadn t called the fire brigade. 分析：该句是复合句。 译文：要不是他的妻子给消防队打电话，这里的一切就被彻底地破坏了。 二、混合式虚拟语气 有时条件从句和主句时态不一致，可以根据主句、从句动作发生的时间分别运用相应的 虚拟语气。 例句：He would be studying at the university now if he had passed the entrance exam in ati on.
情态动词和虚拟语气 情态动词的用法要点 一、表能力 Can Am/is/are able to 表现在的能力 Will be able to 表将来的能力 could Was/were able to 表过去得能力 Could have+过去分词：表示过去有能力做但未做 二、表推测（可能性） 1.可能性可分为客观的可能性和具体事情实际发生的可能性两种。所谓客观的（理论的）可能性即并不涉及 具体某事是否会发生，此种用法常常可以说明人或事物的特征。情态动词can可用于肯定句中表示客观的（理论的）可能性，而表示具体事情实际发生的可能性时，can一般不用于肯定句。 Accidents can happen on such rainy days. We may go to the cinema tonight, but we are not sure yet. 2.表示具体事情实际发生的可能性： （2）表示具体事情实际发生的可能性时，may, must 常用于肯定句，一般不用于否定句和疑问句（may not 表示“可能不”）；can常用于否定句、疑问句或感叹句中，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。 This can’t/ couldn’t be done by him. This may not be done by him. He could be on his way home now. Can this be done by him? Mr Mush is on time for everything. How can it be that he was late for the opening ceremony? I didn’t hear the phone. I must have been asleep. ---Are you coming to Jeff’party? ---I’m not sure. I might go to the concert instead. (3) would, could, should, might 并不一定与过去时间有关，而表示可能性弱于它们相应的现在时形式。 This may/ might be done by him. (4)should 表推测时，表示确定或可能有的未来或期望，即合乎理想的情况或结果 He ought to/ should be here on time---he started early enough. We should arrive before dark. The roads should be less crowded today. 三、表示请求、允许、允诺 1.当对方是决策者时，你代表你（们）自己（I, we），或代表第三者（he she they）向对方（you）请示或提 出建议时用：
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

【温馨提示】 (1)dare用作情态动词有dare,dared两种形式。 (2)dare用作实义动词,后接不定式,不定式符号to可省去,但dare以动词-ing形式出现时,不定式符号to不能省略。 要点二“情态动词+have done ”的用法 have done表示对过去已发生的事情进行肯定的推断,只用于肯定句中,意为“一定,必定”,其否定形式为:can’t/cannot have done。 It must have rained last night,for the road was quite wet. 昨晚肯定下雨了,因为路面十分潮湿。 I saw Mr Wang just can’t have gone abroad. 刚刚我还看见王先生了,他不可能已经出国了。 have done意为“本来可以……,本来能够……”,表示虚拟语气。 You could have made greater progress,but you didn’t try your best. 你本来可以取得更大的进步,但是你没有努力。 might have done表示对过去已发生的事情进行推断,意为“可能/或许已经……”。其否定形式为: may/might not have done意为“可能没有做……”。 It’s no use going to his may not have gone may have gone somewhere else. 去他家没用。他可能没有回家,可能已经去了别的地方。 ought to have done表示本应该做某事,却没有做,含有责备或后悔之意。其否定形式为should not/ought not to
