人教版高三英语语法专项训练--情态动词与虚拟语气
【最新】高中英语人教版高考英语语法学案：专题八 情态动词和虚拟语气
情态动词主要用来表示说话人的情感、态度等，是中学英语语法的重点，也是高考的热点，是单项填空必考的一个知识点。
情态动词在近五年高考中主要考查四点：情态动词表示推测和可能性的用法；情态动词与虚拟语气；情态动词表达“情感、态度、语气等”；情态动词表示“必要性”等方面的用法。
虚拟语气的考点主要集中在名词性从句、条件句中的用法，以及错综条件句中虚拟语气的应用。
一、情态动词表推测的用法has gone toShanghai. B:It must beMr. Wang.He looks likeourheadmaster.②That maynot be true.③Hecouldn'thavediscoveredthe truth.—When can I come for the photos？I need them tomorrow afternoon.—They ________ be ready by 12：00.A．can B．should C．might D．need【解析】B A项表示推测时常用于否定句和疑问句中。
C项表示推测语气不太肯定。
should意为“按理说，理应”，既回答了顾客的询问，不失礼貌，又为照片有可能尚未洗好，顾客到时取不到留下了回旋的余地，体现了店主的精明与用词经过仔细推敲。
二、情态动词的其他用法1．can, could, may, mightcould/ might。
2.must, should3. need, dare4.shall/will/would4.shall/will/would4.shall/will/would二、情态动词＋have done四、虚拟语气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。
1．虚拟语气在条件句中的用法If it were to rain tomorrow, I should not drive my car. 如果明天下雨的话，我就不开车了。
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。

高考英语专题语法训练——情态动词和虚拟语气
专题3情态动词和虚拟语气Ⅰ.单句语法填空Mum：Are they there? Oh，my goodness.I must have put them in there when the phone rang.(2014·新课标全国样卷) 解析动词原形前常跟情态动词或助动词。
根据句意，是对过去发生的动作的最有把握的猜测，故肯定句中用must have done形式。
Ⅱ.单句改错(每小题仅有1处错误)1.Then he and my mother would have had a drink while she prepared dinner and they would talk about his day and hers.(2016·浙江)解析根据语境知，此处是描述的过去的一种习惯，故用would do表示“过去常常做”。
would have done表示对过去事情的假设，意为“本来会做”。
2.Some classmates suggest we can 或canshould go to places of interest nearby.(2016·全国Ⅱ)解析suggest表示“建议”时，后面的宾语从句的谓语动词要用should do形式，should可以省略，故答案有两种改法。
3.We must foundfind ways to protect our environment.(2015·全国Ⅰ)解析情态动词后面要接动词原形。
4.If youarewere me，would you talk to them？(2015·四川)解析该句为if虚拟条件句，表示与现在情况相反的假设，条件句中动词要用过去式(be动词用were)，所以要把are改为were。
◆情态动词的核心考点1.can/could和be able to的用法(1)can和be able to都表示能力，意思上没多大区别。

情态动词和虚拟语气（2）解题指导：情态动词的用法复杂多变,在高考试题中占的比重一直比较稳定,每年总有一至两个题,可以单独考查,也可以结合虚拟语气考查。
命题者常常利用语境和句子之间意义上的细微差别来考查考生对情态动词的理解和掌握,难度也保持较为稳定的趋势。
其考点主要包括：1、考查情态动词的基本用法。
如：: can和could的用法及区别；will和would的用法及区别；must的用法；shall用于不同人称时的用法和should 的各种用法；need的用法等。
2、考查情态动词的“推测”功能。
如：can，could，may，might，must 皆可表示推测，使用时要注意以下几点：（1）注意语气。
语气较强用must, cannot，couldn’t；语气较弱may，might或can，could；（2）注意句式。
在肯定句中，一般用may，might，must；在否定句，疑问句中常用can，could；（3）注意时态。
表示对现在或将来的情况的推测，此时通常用“情态动词+ 动词原形”结构；表示对现在或将来正在进行的情况进行推测，通常用“情态动词+进行体”结构；表示对过去情况的推测，通常用“情态动词+完成体”结构。
3、考查情态动词的特殊用法。
如：（1）cannot／can't 及too／over（‐)／enough ／perfectly ／sufficiently 等词连用，意为“越…越…”“无论怎样……也不为过”、“决不会……够(过)”。
（2）cannot wait to do sth意为“急于做某事”，。
（3）would 和used to的区别；can 和be able to的区别。
（4）“may / might well＋动词原形”意为“理应，有足够的理由”；“may/ might as well＋动词原形”意为“还不如，不妨，还是…的好”。
（5）must表示偏执型，意为“偏要”；“硬要”；can用在肯定句，可以表示客观上的“可能性”；shall用在法律、条约、协定等文件中可以表示义务、规定等；should表示估计或推测上的“应该”，译为“可能，该，估计，按理应当”；will 可以表示习惯和倾向性，意为“惯于, 老是, 终归是”等。
