历年高考英语语法精讲精练-情态动词和虚拟语气有解析.doc

高考英语语法精讲精练-情态动词和虚拟语气一、情态动词的语法特征(1)情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。

(2)情态动词除ought 和have 外，后面只能接不带to 的不定式。

(3)情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。

(4)情态动词没有非谓语形式，即没有不定式、分词、动名词等形式。

二、虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，多半不是事实，或与事实相反。

高考重点要求：1、情态动词的基本用法2、情态动词表示推测的语义差别3、情态动词后接不定式完成体的不同意义4、虚拟语气中情态动词的用法知识点概述一、情态动词（一）情态动词种类1. can表示体力或脑力方面的“能力”、“技能”或根据客观条件能做某种动作的“可能性”, 但表示人的体力或智力的具体动作时须用be able to .He was able to do that without any help.他不需要任何帮助就能完成这项工作。

2. may表示“允许，可以”，相当于be allowed to .may或might可和as well连用，表示“建议”，译为“还是……的为好”You may as well keep a certain distance from that mad man. 你们还是离那疯子远点为好。

You might as well go home now.你还是现在回家为好。

3. must表示“必须”或“应当”、“一定”。

4. have to 加动词原形，表示“不得不”，“必须”，它比must更强调客观。

Tom had to work into the deep night every day to earn a living. 汤姆为了生计每天都得工作到深夜。

5. should 表示“劝告”，“建议”或“义务”时，译作“应当”，或表示“预测”和“可能”。

高三英语虚拟语气与情态动词试题答案及解析

高三英语虚拟语气与情态动词试题答案及解析1. They were abroad during the months when we were carrying out the investigation, or they_____ to our help.A．would have come B．could come C．have come D．had come【答案】A【解析】这里when引导的是定语从句，修饰前面的名词months;根据谓语动词were可知事情发生过去，or后是对过去的虚拟，所以应该用would have done，故选A。

句意：在我们进行调查期间他们在国外，要不然的话他们就来帮忙。

【考点】考查虚拟语气。

2. (2014·蜀光中学月考)The weather turned out to be fine yesterday.I________the trouble to carry the umbrella with me.A．couldn’t have taken B．mustn’t have takenC．needn’t have taken D．didn’t need to take【答案】C【解析】考查情态动词。

句意为：昨天天气很好，我本不必麻烦随身带伞的。

根据句意可知C项正确。

needn’t have done本没有必要做而做了。

答案：C3. ______ today, he would get there by Friday.A．Were he to leave B．If he had left C．Did he to leave D．Had he left【答案】A【解析】句意：要是他明天离开，在星期五之前就会到那里。

这里的were he to leave today="If" he were to leave today, 为虚拟语气，if条件句谓语中如果有系动词were，助动词should,had可将它提到主语前面，省去if.所以选A。

专题06情态动词和虚拟语气-三年高考(2016-2018)英语试题分项版解析

2018年高考题1.【2018·江苏】24. It’s strange that he _______have taken the books without the owner’s permission.A. wouldB. shouldC. couldD. might【答案】B点睛：本题考查虚拟语气。

It is important/necessary/strange/impossible/natural that... 主语从句多数情况下用虚拟语气，表达一种要求、命令或者责备、建议或主观看法。

但是如果只是表示陈述一个事实而不是强烈的感情，完全可以用一般的陈述语气。

试比较： It is strange that he had made a mistake.（陈述一个事实：他犯了错误让人有点奇怪。

） It is strange that he (should) have made a mistake. （虚拟语气，说话者是在责备他本不应该犯错。

）2.【2018·江苏】27. There is a good social life in the village, and I wish I _______ a second chance to become more involved.A. hadB. will haveC. would have hadD. have had【答案】A【解析】考查虚拟语气。

句意：在这个村里有很好的社交生活，并且我希望我再有机会去更多的参与。

本题考查wish引导的宾语从句，表示与现在事实相反的愿望，所以从句用一般过去时。

故选A。

点睛：本题考查wish引导的虚拟语气。

由wish引起的表示愿望的虚拟语气：1．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）。

2．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。

高考英语一轮复习查漏补缺大闯关100道必刷题：专题06 情态动词和虚拟语气 (解析版)

专题06 情态动词与虚拟语气养成良好的答题习惯，是决定高考英语成败的决定性因素之一。

做题前，要认真阅读题目要求、题干和选项，并对答案内容作出合理预测;答题时，切忌跟着感觉走，最好按照题目序号来做，不会的或存在疑问的，要做好标记，要善于发现，找到题目的题眼所在，规范答题，书写工整;答题完毕时，要认真检查，查漏补缺，纠正错误。

reported.【答案】avoided【解析】考查虚拟语气。

句意：如果驾驶者在高速公路上避免超速行驶，就不会有更多的被报道的交通事故了。

分析句子可知，此处为if引导虚拟语气句型中从句谓语动词的填入，结合句意以及主句动词would not be可知，此处应为对现在情况的假设，所以从句动词为一般过去时。

故填avoided。

2．We recommend that he (type) a name that is meaningful to him for the chatroom. 【答案】type/should type【解析】考查虚拟语气。

句意：我们建议他为聊天室输入一个对他有意义的名称。

表示“建议、命令、要求和请求”等语气的动词后接宾语从句时，使用虚拟语气结构即that sb. should do，should可以省略；recommend意为“建议”符合此原则。

故答案为type/should type。

3．(be) I a bird, I would fly to see you at once.【答案】Were【解析】考查虚拟语气中的省略。

句意：如果我是一只鸟，我马上就会飞过去看你。

在虚拟语气中表示对现在情况的虚拟，be动词用were。

此处为虚拟条件句应该为:：If I were a bird。

此处省略了if的倒装句式，首字母大写。

故填Were。

4．Obviously, it is high time that we (take) effective measures to tackle the problem. 【答案】took/should take【解析】考查虚拟语气。

注：might为may的过去式，但也可以代替may，语气较为婉转客气或更加不肯定。

eg: ① He might not come today.今天他也许不来了。

②表示推测时“肯定，一定” eg: They must be at home.The light is on 他们肯定在家,灯亮着呢.③ must not 禁止，不许 eg: You must not tell lies. 你不许撒谎。

注意：①must开头的疑问句，其否定回答通常用 don't have to 或needn't 。

而不用mustn'teg: ---Must I finish my homework first? 我必须先完成作业吗？---No, you don't have to/ needn't. 不，你不必。

② can 和 must在表推测时，can一般否定句中，而must 常用于肯定句中。

eg: ①It can not be Li Lei 那个人不可能是李磊② It must be Li Lei 那个人肯定是李磊。

4. need 的用法：①情态动词“需要, 有必要”一般用于否定句或疑问句中。

eg: You needn't come here this afternoon.你今天下午不必来。

②行为动词“需要, 有必要” 可以用于各种句式中。

eg: ①You don't need to go now. 你不必现在就走。

② I need to have a rest. 我需要休息一下③ Do we need to finish all the work today? 我们今天需要完成所有的工作吗？need的用法的助记口诀：实义动词表“需要”，后接名、代、不定式。

need后接动名词，主动形式表被动。

情态动词表“需要”，没有人称数之变。

其后直接加动原，多用疑问与否定。

【2017·北京卷】34. If the new safety system _______ to use, the accident would never have happened.A. had been putB. were putC. should be putD. would be put【答案】A考点：考查虚拟语气。

【名师点睛】英语中的三种语气，语气是动词的一种形式，用来说明我们对自己的话所采取的态度。

1、陈述语气（疑问，否定，肯定，感叹）2、祈使语气（命令，要求，建议，警告）3、虚拟语气：不可能发生的事，愿望，建议，与事实相反的假设等.一、虚拟语气在条件中的具体用法真实条件句If you work hard,you’ll surely pass the exam.虚拟条件句（假设情况不存在，实现机会很小）If I were a bird, I could fly freely in the sky.1.与现在事实相反if从句：动词过去式（be---were）主句：would/could/might/should+动词原形If we had time, we would go with you.If I were you, I shouldn’t do that.If it weren’t raining, we wouldn’t stay.2.与过去事实相反if从句：had done主句：would/could/might/should+have doneIf the teacher ha dn’t helped us, we couldn’t have succeeded.I could have done it better if I had been more careful.If he hadn’t been ill, he might have come.3.与将来事实可能相反if从句：a.动词过去式（be一律用were）b.should+动词原形（不能用would）c.were to+动词原形主句：would/could/might/should+动词原形If he came tomorrow, I would tell him everything.If it should rain tomorrow, I would stay at home and watch TV.If it were to snow tomorrow, they would not go out.Should he come tomorrow, please give the book to him.4.错综时间条件句(有时时间会省略）学科5.含蓄条件句有时虚拟条件不用if条件从句，而用介词或介词短语来表示。

They would not be able to live without him.（如果没有）He would have failed but for his teacher’s timely advice.（要不是）=if it had not been forIf only you had worked with greater care!(要是......就好了）You would have done the same thing in her position.With a little more care you could have avoid the traffic accident.6.虚拟结合条件句在虚拟语气中，假设的情况有时间可以通过上下文或其他方式表现出来，并且虚拟的情况和真实的情况同时存在。
