高考英语情态动词语法专题训练(名师精讲必考语法知识点+实战真题，值得下载练习)一、情态动词的定义情态动词是一种本身有一定的词义，表示说话人的情绪、态度或语气的动词，但不能单独作谓语，只能和其他动词原形构成谓语。

情态动词数量不多，但用途广泛，主要有：can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) .二、情态动词的位置情态动词在句中放在谓语动词之前，谓语动词前若有助动词，则在助动词之前，疑问句中，情态动词放在主语之前。

•I can see you. Come here. 我能看见你，过来吧。

•He must have been away. 他一定走了。

•What can I do for you? 你要什么？•How dare you treat us like that! 你怎么敢那样对待我们!三、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，后面只能接动词原形。

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，等形式。

四、情态动词的用法（一）. can; could; be able toCan 1. 表示“能力”(此时过去时是could) What can you do?2. 表示许可、请求，“可以”。

在口语中，can可以代替may表示许可，而may比较正式。

（此时用could 或might语气更委婉）--Can/Could I go now?--Yes, you can.3 表示推测（否，疑），把握很大,could也可表推测（肯，否，疑）,把握比can小。

--Look! Someone is coming! Who can it be?--It can’t be him. He has gone to Paris.（不可能）He could be here soon. 他很快就来。

但can只有现在和过去时（could），而be able to则有更多的形式。

但当成功地完成某一具体动作时，通常不用could而用was/were able to来表示。

这时was/were able to 相当于managed to，表示经过一番努力，终于能够完成某事。

例句：Can you use chopsticks?The wounded man still was able to get to the village and was saved in the end.②can和couldcan和could表示猜测，一般用于疑问句和否定句.例句：--Can the news be true?-It can’t be true.③表示请求、允许（表请求时，口语中常用could 代替can 使语气更委婉，回答时用can）例子：Can I go now ?-Could I come to see you tomorrow?----Yes, you can. (否定回答可用No, I’m afraid not.)④表示惊异、怀疑、不相信的态度（主要用于否定句、疑问句或感叹句中）例子：How can that be true? I can’t believe my eyes and ears.How could you be so careless.?⑤ can 的特殊用法Can but 只好can’t but 不得不can’t …too 再….也不为过，越..越好can not but do 表示“不得不/只好做”can’t help but do 没有办法只有做can’t chose but do 没有选择只能做can do nothing but do 只能做have no choice but to do 别无选择而只有例子：I can but wait.I can’t but wait.You can’t be too patient to the customers.(2) may/might①may/might表示可能，但may比might可能性大。

4．表示反劝的特殊的表推测形式5．注意：Ⅳ．情态动词表推测的反意疑问句1．情态动词表推测的反意疑问句，简单来说，就是以情态动词后的时态为淮，如句子里有明确的时间状语，则以其为准。

句意：当他问河岸上的村民，他在哪里可以找到这位传奇艺术家时，他们笑着指着河的下游。

根据上文they smiled and 可知此处应用一般过去时。

故填pointed。

句意：随着越多的小孩出生，越多的食物被需要。

分析句子，逻辑主语和need 之间表示被动逻辑。

同时此处描述的是过去的时间，所以时态应用过去时。

故此处应用过去时的被动语态。

food 为不可数名词。

故填was needed。

3、（2020·浙江卷语法填空）By about 6000 BC，people 61．(discover)the best crops to grow and animals to raise.【答案】had discovered【解析】考查时态。

句意：大约在公元前6000 年，人们已经发现了最适宜种植的庄稼和最适宜饲养的牲畜。

分析句子，简单句中除了提示词外无其余动词，故此处需用动词的时态。

逻辑主语和提示词之间表示主动逻辑。

by + 过去时间译为“到..为止”，后面的句子用过去完成时。

故填had discovered.4、（2020·浙江卷语法填空）New methods 65．(mean)that fewer people worked infarming.【答案】meant【解析】考查时态。

根据上文，可知是对过去事情的虚拟，与过去事实相反的假设。

句意：虽然这并不是这次旅行的目的，但我得到了一些新的领悟，那些领悟在我的日常生活中是本不可能发生的。

此处考查虚拟语气，“我得到新的领悟”发生在过去，故此处是与过去事实相反，应用could/might/would/need/should+have done，“本不可能发生”是could never have happened，故选B项。

【点睛】本题考查“情态动词+have done”的虚拟语气，其常用表达有：could have done本能做某事而未做couldn’t have done不可能做了某事should have done本应该做某事而未做shouldn’t have done本不应该做某事而做了would have done本会某事而未做wouldn’t have done本不会做某事而做了need have done本需要做某事而未做needn’t have done本不必要做某事而做了2．Mr. Baker, some students want to see you. ______ they wait here or outside?A．May B．Should C．Shall D．Will【答案】C【解析】【详解】考查Shall的用法。

专题16 情态动词易错点解题方法情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语,只能和其他动词原形构成谓语。

情态动词在句中放在谓语动词之前,谓语动词前若有助动词,则在助动词之前,疑问句中,情态动词则在主语之前.情态动词无人称和数的变化其后面跟的动词需用原形,否定式是在情态动词后面加"not"构成. 个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气,委婉的语气, 时态性不强, 可用于过去,现在或将来.1.--Are you coming to Jef f’s party?--I’m not sure. I ____go to the concert instead.(NMET2000)A. mustB. wouldC. shouldD. might【答案】D.【解析】选D。

I’m not sure.的语境表明把握性不大，当然我去参加音乐演奏会的可能性就比较小了，故不用must应用might2.--_____the news be true?—No, it_____be true.A. Can, can’tB. May, can’tC. May, may notD. Must, mustn’t【答案】A.【解析】选A。

因为前半句是疑问句，后半句为否定句，两空都不能使用may/might 和must，应而用can和can’t。

3.I told Sally how to get there, but perhaps I ____for her.(NMET94)A. had to write it outB. must have written it outC. should have written it outD. ought to write it out【答案】C.【解析】选C。

分析语境可知，口头上告知Sally如何去那里是不够的，所以我本应书面告知，却有没书面告知之，显得应使用should /ought to have written表示遗憾之情。

2020-2021年历年全国高考英语情态动词试题汇总及答案一、单项选择情态动词1．—I feel a little nervous.—Take it easy. You __________ have difficulty passing the exam when you have prepared for it well.A．mustn’t B．needn’t C．may not D．shouldn’t【答案】D【解析】【详解】考查情态动词。

结合句意可知答案为D。

2．It ________ be the postman at the door. It's only six o'clock.A．mustn't B．can'tC．won't D．needn't【答案】B【解析】D[考查虚拟语气。

句意：不可能是邮递员在门口，才六点钟呢。

mustn't 禁止，不允许；can't 不可能；won't 不愿意，就是不，偏不；needn't 不需要。

]3．Using AI， many companies are now conducting experiments that__________ possible just a few years ago．A．would have been B．might have beenC．shouldn't have been D．couldn't have been【答案】D【解析】【详解】考查情态动词表推测。

句意：很多公司现在使用人工智能进行试验，这在几年前是不可能的。

根据“a few years ago”可知，此处表示“过去不可能”，应该用couldn’t have done，故D 项正确。

倒装句和省略句重难点分析一、倒装句倒装句主要考查以下几个方面：◆含有否定意味的词置于句首，用部分倒装；◆“only+状语/状语从句”置于句首，用部分倒装；◆so/such…that句型中，“so+形容词/副词”提前，用部分倒装；◆表示方位的副词或介词短语放在句首，要用完全倒装。

1. 倒装句用法一览表：2. 特别提示(1) there be结构的倒装句型中，除了be动词之外，there后还可接lie, live, seemto be等。

如：There lived an old man in the village long long ago. 很久很久以前，村子里住着一位老人。

(2) here, there, now, then, up, down, away, out等副词位于句首，主语为代词时不到装。

如：Away it flew. 它飞走了。

(3) 直接引语的一部分或全部位于句首，主句倒装，主句倒装，但是主语为代词时不倒装。

如：“You have to finish it tonight,” she said. “今晚你必须完成它，”她说。

(4) so位于句首不倒装的情况：① 主语与前句相同，表赞同，译为“确实如此”。

如：— Mike studies hard. 迈克学习很刻苦。

— So he does. 确实是。

② 表示前句内容也适用于另外的人或事，前句如果列举了两种事实以上，用“so it is/was with sb./sth.”回答。

如：— Tom is kind and often helps those in trouble. 汤姆很友好，经常帮助处于困境中的人。

— So it is with his father. 他父亲也是。

(5) 使用as/though进行倒装时注意：①句首有名词，名词不能带任何冠词。

如：Child as he is, he can tell right from wrong. 尽管他是个孩子，却能够明辨是非。

高考英语情态动词练习题50题(带答案)1. You ______ be tired after working for eight hours without a break.A. canB. mayC. mustD. should答案解析：C。

must表示肯定的推测，根据题意，连续工作八小时不休息肯定会累，所以这里用must。

A选项can表示能力或可能性，通常用于否定句和疑问句中表示推测，这里不符合语境。

B选项may表示可能，可能性较弱，没有must肯定。

D选项should表示应该，与题意推测累不累不相关。

2. - ______ I use your pen? - Sure. Here you are.A. MustB. MayC. NeedD. Should答案解析：B。

May用于征求对方许可，在这个句子中是询问是否可以使用对方的笔，符合语境。

A选项Must表示必须，C选项Need 表示需要，D选项Should表示应该，都不符合这个征求许可的语境。

3. He ______ speak English when he was five years old.A. couldB. canC. mayD. must答案解析：A。

could是can的过去式，表示过去的能力，句中提到他五岁的时候，是过去的时间，所以用could表示过去能说英语。

B选项can表示现在的能力。

C选项may表示可能，D选项must表示肯定的推测，都不符合这里表示过去能力的语境。

4. - Where is Tom? - He ______ be in the library. I'm not sure.A. canB. mayC. mustD. should答案解析：B。

大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。

替代表泛指的单数名词，通常用one替代。

此处用one替代前面的a desire，是同位语；结合句意第二空用情态动词should“应该”。

故选D。

【点睛】that ,it ,one 代指前面的名词时的用法1.one 指代前面出现的可数名词，是泛指。

可以和冠词连用，也可以有自己的定语。

一般不能用做特指，但和定冠词连用时可以是特指。

如： Please show me the cup, the red one on the shelf.2.It 指代前面提到的单数名词，相当于the one。
