高考情态动词全 篇2

情态动词主要用来表示说话人对某一动作或状态的情感、态度等, 没有人称和数的变化, 不能单独作谓语动词用, 必须和不带to的不定式一起 ( 除ought后接不定式外) 构成谓语动词。近年来高考对情态动词的考查立意坚持不偏不怪的原则, 但情景更加逼真, 设问角度更加综合化和细微化。从历届高考题来看, 对情态动词的考查主要集中在三个方面: 情态动词的基本用法; 情态动词对现在与将来推测性的用法; 情态动词 + have done的用法。

一、情态动词的非推测性用法

1. can, could 与 be able to

can / could与be able to表示“能力”, can指“体力、知识、技能”, 只能用于一般现在时和一般过去时 ( could) , 而be able to可表示能力且可用于多种时态, be able to可以与其它情态动词连用, 而can不可以。表示过去一次性的或经过一番努力成功地完成某一具体动作, 只能用was/were able to, 不能用could, was/ wereable to相当于“managed to do sth”; 在否定结构中, 二者可以互换。could只能表示过去一般性的能力, 不能用could表达过去某种具体的能力 ( 即在过去某一特定场合做某事的能力) ; 而can只表示客观情况。

【典例1】过了好几分钟, 我才理解他说的是什么。 ( 完成句子)

It was several minutes before I_______take in what he was saying. ( 2014年湖北卷)

答案: could。此句是由before引导的时间状语从句, 主句用一般过去式, 为了保持主从句时态一致, 所以从句用could表示“能力”, 意为“能, 能够”。

2. must 与 have to

must与have to都可表示“必须”的意思, 但must表示说话人的主观看法, 意为“必须, 一定”, 其否定形式mustn't, 意为“禁止, 不准”, 语气比较强烈; have to则侧重于表示客观情况, 其否定式和疑问式要借助于助动词do, 表示“不必”, 语气较弱。have to有人称和时态的变化, 而must没有, 在意义上must的否定回答应用needn't。此外, must还可表示“偏要, 非要”, 表达对某事的不满或责备等情绪。

【典例2】你偏要现在打扰我吗? 难道你没有看到我正在打电话吗? ( 完成句子)

________you interrupt now? Can't you see I'm on the phone?

答案: Must。根据句意, 表示“偏要, 非要”应用“must”。

【典例3】The new law states that people__________drive after drinking alcohol. ( 完成句子)

答案: mustn't。句意是: 新法律规定人们不能酒后驾车。根据句意, 表示“禁止, 不准”, 语气最为强烈, 所以用mustn't。

【典例4】—Is it good to look up every newword when I come across it in reading?

—No. You_________, because you are likely to guess the meaning from the context. ( 完成句子)

答案: needn't/ don't have to。句意是: ———阅读时查我所遇到的每一个生词好吗? ———不, 你没有必要, 因为你可能通过上下文来猜测词义。根据句意, 表示“没有必要”, 所以用“needn't/ don't have to”。

3. shall 与 will

用于一般疑问句, 表示征询对方意见或请求指示时, shall用于第一和第三人称, will常用于第二人称。shall用于第二、三人称的陈述句, 表示说话人的命令、警告、允诺、威胁、决心以及法律条文中的规定或要求等。will表示“意志, 愿望和决心”, 可用于各种人称的陈述句, 也可用于条件状语从句; will还可表示一种习惯性的动作或倾向性, 意为“总是, 会要”。此外, will还表示一时的动作或临时的行为。

【典例5】One of our rules is that every student_________wear school uniform whileschool. ( 完成句子)

答案: shall。句意是: 我们其中有一条规章制度是: 在学校里每个学生都必须穿校服。根据句意与词法, shall用于第二、三人称的陈述句, 可以表示法律条文中的要求或规定。

【典例6】—________you go shopping withme tomorrow?

—I'd love to. ( 完成句子)

答案: Will。根据句意, will用于第二人称的疑问句, 用来征求对方意见; 而shall用于第一、三人称的疑问句, 用来征求对方意见。

4. should 与 ought to

should表示主观上有责任, 有义务做某事或处于某种状态; 而ought to通常指客观上有责任、有义务或出于道义、法律条文的约束而应该做某事或处于某种状态, 表示合适性或可能性, 语气较强。should与ought to都可表示“应该, 应当”, 用于表示劝告或建议的目的, 但语气不及ought to强。should还可表示惊讶语气, 意为“居然, 竟然”。ought to的否定式为: oughtnot to或oughtn't to。

【典例7】It was sad to me that they, so poor themselves, _________bring me food. ( 完成句子)

答案: should。句意是: 使我感到难过的是他们自己这么贫困, 竟然还给 我带来食 物。should用来表示一种惊奇的心情, 意为“居然, 竟然”。

【典例8】One ought to not be punished for what one hasn't done. ( 单句改错)

答案: 把not放在to之前。ought to的否定形式是: ought not to或oughtn't to。

5. used to 与 would

“used to + 动词原形”主要表示与现在时间相比, 意为“过去常常”, 表示过去习惯性的动作或行为状态, 强调现在已不复存在, 可以与表示过去的时间状语连用。would主要表示与过去一段时间相比, 意为“总会, 总是”, 表示过去反复发生的动作或某种倾向, 且感情色彩较浓。此外, would还可表示过去时间的“意志、意愿、决心”; 在疑问句中用于第二人称, 表示说话人向对方提出请求或询问对方的意愿时, 比用will的语气更加婉转。

【典例9】我还记得快乐的童年, 那时妈妈总会在周末带我去迪士尼乐园。 ( 完成句子)

I still remember my happy childhood when my mother__________take me to Disneyland atweekends.

答案: would。would表示“总会, 总是”, 表示过去反复发生的动作或某种倾向, 且感情色彩较浓。

【典例10】我过去常常在业余时间打篮球, 但现在我对足球感兴趣了。 ( 完成句子)

I__________play basketball a lot in my spare time, but now I am interested in football.

答案: used to。表示过去习惯性的动作或行为状态, 强调现在已不复存在, 根据题意可知用used to。

6. need

need用作情态动词, 常用于否定句、疑问句或条件句中。need作实义动词时, 当主语是后接动词动作的承受者时, 后接的动词应用doing或to be done。needn't = don't have to意为“不必”。

【典例11】I've ordered some pizza, so we_________worry about cooking when we get hometired. ( 完成句子)

答案: needn't/ don't have to。句意为: 我已经点了一些比萨饼, 所以我们不必担心累了回到家还要做饭。根据句意, 表示没有必要做某事, 实际也没有做, 所以用“needn't/ don't have to + 动词原形”。

7. 掌握表示征求意见情态动词在含义与人称上的特殊要求, 见下表:

【典例12】我可以和你谈谈吗? 不会花很多时间的。 ( 完成句子)

______I have a word with you? It won't take long.

答案: Can / Could / may / might。根据句意, 表示“请求对方允许”, 可用can / could或may /might, 但用might或could语气更加委婉。

8. 情态动词在一般疑问句中的回答语

1 Can you...? Yes, I can. No, I can't.

2 Could you...? Yes, I can. No, I can't.

3 May I...? Yes, you may / can. ( Yes, please. Certainly. ) No, you mustn't / can't / had better not . ( No, please not. )

4 Must I ...? Yes, you must. No, needn't /don't have to.

5 Need I ...? Yes, you must. No, you needn't.

【解题技巧】解答情态动词试题时, 我们应仔细分析题干, 设身处地理解题干的情景, 准确理解说话人的语气、情感以及不同情态动词的基本用法, 是解题的关键。

二、情态动词的推测性用法

must, may, might, can, could与should都可表示对现在和未来的推测。must所表示的可能性最大、最有把握, 意为“一定”; 其否定式mustn't表示“禁止, 不准”, 不表示推测。may和might表示推测只能用于肯定句或否定句, 意为“也许”, 表示“一半”的可能性; might相对于may来说, 表示的可能性更小些。can和could表示推测主要用于否定句和疑问句中, 表示“不可能”要用can't或couldn't。should用来表示推测, 意为“按理会, 预期会”, 往往指具有一定的客观根据或根据合理的推断, 且所期待的事几乎是事实。

【典例13】不可能有人比他更慷慨; 他有一颗善良的心。 ( 完成句子)

No one_________be more generous; he hasa heart of gold. ( 2013年天津卷)

答案: can / could。根据句中“he has a heart of gold”可知有一定的事实依据, 在否定句中表示可能性, 可用can或could。

【典例14】有时候举例也许有助于解释抽象的概念。 ( 完成句子)

Sometimes_________to use examples to explain abstract concepts . ( helpful) ( 2014年湖北卷)

答案: it might/may be helpful。根据句意, may和might表示推测只能用于肯定句或否定句, 意为“也许”, 表示“一半”的可能性。

【注意】can用于肯定句, 表示可能性时, 指理论上的可能, 表示“一时的特征”, 可译为“有时有可能”。

【典例15】尽管你能在伦敦买到便宜货, 但是伦敦通常不是购物便宜的地方。 ( 完成句子)

Although you_____find bargains in London, it's not generally a cheap place to shop. ( 2014年全国大纲卷)

答案: can。根据句意, 本题can表示可能性时, 用于肯定句, 指理论上的可能, 可译为“有时有可能”。

【解题技巧】情态动词表示对现在或将来情况的猜测时, 首先要清楚被猜测的时间是现在或将来, 其次要看有无事实根据。若有事实根据, 则无论是肯定还是否定的猜测, 猜测语气最强且符合时间要求的为最佳答案;若无事实根据, 纯凭主观臆断, 则猜测语气最弱且符合时间要求的为最佳答案。同时应掌握以下几点:

1在肯定句中表示“可能”, must语气最肯定; may表示事实上的可能性, 与may相比, might表示的可能性更小; can用于肯定句, 表示可能性时, 指理论上的可能。

2在否定句中只能用can和may。表示“不可能”用can't, 在否定句中语气强烈; may not与might not表示“可能不”, 表示“一半”的概念。

3should可以用来表示一种估计的情况, 意为“按理会, 预期会”。

三、“情态动词 + have done”的用法

( 一) 表示对过去情况的推测

1.“must have + 过去分词”只用于肯定句, 表示“过去一定做过某事”, 表示一种最有把握的推测。

【典例16】亨利感觉不舒服, 在昨晚的聚会上他肯定喝得太多。 ( 完成句子)

Harry is feeling uncomfortable. He_________at the party last night. ( drink) ( 2013年辽宁卷)

答案: must have drunk too much。对过去发生事情的肯定推测, 有一定的事实依据, 表示“过去一定 做过某事”, 应用“must + have done”。

2.“can't / couldn't have + 过去分词”是对过去发生情况的否定推测, 表示“过去不可能已做了某事”; 疑问句表示“可能/也许已做了某事吗?”。注意: “can / could have + 过去分词”用于疑问句表示对过去情况的猜测, 意为“可能/也许已做了某事”。

【典例17】我的那本名叫“黑尔斯的家”的书不见了, 谁可能把它拿走了呢? ( 完成句子)

My book, The House of Hades, is missing.Who ________taken it? ( 2014年陕西卷)

答案: can / could have。根据句意, 用于疑问句对过去情况的猜测, 表示可能性, 所以用“can / could have + 过去分词”。

【典例18】你的眼睛为什么那么红? 昨晚不可能睡得很好。 ( 完成句子)

Why are your eyes so red? You_________have slept well last night. ( 2013年四川卷)

答案: can't/ couldn't。根据句意, 对过去情况的否定推测, 表示“过去不可能做了 某事”, 应用“can't/ couldn't have + 过去分词”。

3.“may / might have + 过去分词”是对过去情况的一种不太有把握的可能性推测, 表示“可能/大概已做了某事”, 否定句表示“可能还没有……”。

【典例19】陆老师没来上课, 我猜可能出什么事了。 ( 完成句子)

Mr. Lu hasn't shown up in class yet. I guess something__________. ( come up)

答案: might/ may have come up。根据句意, 表示过去 可能做过 某事, 所以用“may /might have + 过去分词”, 语气比较婉转或不肯定。

( 二) 表示虚拟语气

1.“should / ought to have + 过去分词”表示过去本应该做而 ( 实际) 没有做的事情, 含有责备或遗憾的语气, 其否定形式为“should not/ought not to have + 过去分词”, 其否定式表示某种行为不该发生但却发生了。

【典例20】你不该打断会议来告诉我那件事, 你本可以会后告诉我。 ( 完成句子)

You_____the meeting to tell me that;you could have come to tell me afterwards ( interrupt)

答案: shouldn't have interrupted / oughtn't to have interrupted。根据句意, 表示过去本来不应该做某事, 而实际却做了, 所以用“shouldn't/oughtn't to have + 过去分词”。

2.“needn't have + 过去分词”表示过去没有必要做某事, 但实际上做了某事。

【典例21】既然苏西不和我们一起吃晚饭了, 我们本来不必买这么多食物。 ( 完成句子)

We_________have bought so much food nowthat Suzie won't be with us for dinner.

答案: needn't。根据句意, 表示“过去没有必要做某事而实际上做了”, 所以用“needn't have + 过去分词”。

3.“can / could have + 过去分词”表示“过去本来可以做某事而实际上没有做”。

【典例22】我们本来能够一起面对这个困难, 但是为什么你不告诉我呢? ( 完成句子)

We________the difficulty together, but why didn't you tell me?

答案: could have faced。根据句意, 第一个分句表示与过去的事实相反, 表示“过去本来能够做某事而实际上没有做”, 所以用“can /could have + 过去分词”。

4.“would have + 过去分词”这一结构常用于虚拟语气中, 表示与过去事实相反的情况, 即“过去本来会干某事而实际上没有做到”。

【典例23】大多数人认为, 要不是受了重伤而告别足球, 上周他本 会为英格 兰踢球的。 ( 完成句子)

Most believe he______for England last week, but for a serious injury which put him out of football. ( play) ( 2013年湖北卷)

答案: would have played。此句考查含蓄条件的虚拟语气, but for相当于without。根据句意, 与过去事实相反, 所以用“would have + 过去分词”表示过去本来会干某事而实际上没有做到。

【解题技巧】如果句中时间参照物是表示过去的时间, 无论表示猜测, 还是表示虚拟语气, 都应用“情态动词 + have done”。同时, 同学们应掌握“情态动词完成时”的不同形式与含义。

15. 如果你不照我所说的做, 你就得不到晋升的机会, 因为竞争太激烈了。

If you won't do as I tell you, you__________get the chance to be promoted because the competition is just too fierce.

答案与解析:

( 一) 1. 1can /could。在疑问句中表示可能性用can /could。2may / might。在肯定句中表示可能性用may / might。3can't/ couldn't。表示“不可能”用can't/ couldn't。4must。根据句中“They look like twins. ”可知, 有很大的可能性, 用于肯定句, 所以用must。

2. needn't。根据句意可知, 因为大雾天气航班被取消了, 因此我们本不必一路匆忙赶往机场, 表示“过去本不必做某事而实际上做了”, 应用“needn't have + 过去分词”。

3. shall。shall用于第二、三人称的陈述句表示法律条文的要求或规定。

4. must。句意是: ———你在哪儿买到这本书的? ———如果你非要知道的话, 我是从一家二手书店里获得的。根据句意, must在本句中意为“偏要, 非要”, If you must表示无可奈何地同意某人干某事。

5. can't。句意是: 在我们离开家时, 对你给我儿子所提供的所有帮 助感激不 尽。表示“越······越好, 无论怎样也不为过”, 用固定结构“cannot / can't...too /over/ enough...”。

6. may / might。句意是: ———尼克乘火车来吗? ———他应该是乘火车的, 但也不一定。因为他喜欢开车。根据句意, 表示“一半”的可能性, 所以用“may / might not”, 意为“可能不”。

7. might / may。根据语 意, may / might aswell意为“还是······为好”。

8. can。句意为: 注视着别人有时能够让他们感到紧张和尴尬。根据句意以及句中时间状语sometimes可知, can用于肯定句, 指理论上的可能, 表示“一时的特征”。

9. can't / couldn't have followed。句意是: 他这次考试失败, 表明他不可能听从了老师的教导。根据句意, 对过去发生情况的否定推测, 有很大的事实依据, 表示“过去不可能已做了某事”, 所以用“can't/couldn't have + 过去分词”。

10. can。句意是: 警方还没有找到那个失踪的孩子, 但他们正在尽力寻找。根据句意, 表示有能力做某事, 应用can, 构成固定结构“do all / everything one can to do sth”意为“尽力做某事。

11. can't / couldn't。根据句中“because you know a lot of words”可知, 有很大的事实依据, 对现在情况的推测, 所以用表达语气最强的情态动词, 表示“不可能”, 应用“can't/ couldn't”。

12. may / might。根据句中“he wasn't certain what his plans were”可知, 表示不确定性, 所以用“may / might not”, 意为“可能不”。

13. needn't / don't have to。问句“—Must I...?”的否定回 答语要用needn't或don't have to。

14. Will / Would。此句表 示征求对 方意见, 有“愿意”之意, 并且要用于第二人称, 应用will或would。

15. will。在回答对方的请求或命令时, 肯定回答用“Yes, I will. ”, 用will表示临时性决定。

16. Would。表示征求对方意见, 语气比较委婉, 所以应用委婉的表达 方式“would you mind...”来征求对方意见。

( 二) 1. 把would改为used to。根据句意, 王先生过去曾住在这儿, 去年搬走了, 现在不再住在这儿, 故用“used to”表示过去常常, 现在已不复存在; 而would表示过去反复发生的动作或某种倾向。

2. 把could改为was able to。根据句意, 表示过去经过努力成功地完成某一具体动作, 只能用was/were able to, 而不能用could, 这时was / were able to相当于“managed to do sth”。

3. 把第二个could改为can。在疑问句中, 用could表示委婉的请求, 但在答语中用can表示语气更加强烈与肯定。

4. 把mustn't改为didn't。“must have done sth”用在表示对过去动作推测的句型中, 如果句中有表示过去的时间状语, 反意疑问句应用“didn't sb”, 而不能用“mustn't sb”。

5. 把May改为Can / Could。may表示推测只能用于肯定句或否定句, 不能用于疑问句; 而can / could用于否定句或疑问句可表示推测。

6. 把must改为may / might。根据句 中“but it depends”可知, 此句表示不确定性, 所以用may或might, 用于肯定句或否定句, 表示“一半”的可能性。

7. 把can改为should。句意是: ———这些葡萄真的很好。———它们应该很好! 只要看看价格, 每磅3. 99美元。很贵, 是吗? 根据句意, 有一定的客观根据或根据合理的推断, 且所期待的事几乎是事实, 所以用should来表示“推测”, 意为“按理会, 预期会”, 相当于“be expected to”。

8. 把Will改为Shall。will表示征询对方意见或请求指示时, 只用于第二人称; 而shall用于第一或第三人称的一般疑问句, 用来征询对方意见或请求指示。

9. 把can改为must。根据句中“She looks rather upset. ”可知, 表示一种很有把握的推测, 所以用“must have + 过去分词”, 意为“过去一定做过某事”; 而“can /could have + 过去分词”表示“过去本来可以做某事而实际上没有做”。

10. 把mayn't改为mustn't / can't。may表示“允许, 请求”时, 常用于疑问句, 在答语中, 其肯定回 答用may, 否定回答 用mustn't或can't。

11. 把mustn't改为can't。mustn't意为“禁止, 不准”, 不能表示推测; 表示否定的推测应用“can't”, 意为“不可能”。

12. 把might leave改为may / might have left。根据句中时间状语“yesterday afternoon”可知表示对过去情况的推测, 根据句意, 表示过去一种不太有把握的可能性, 所以用“may /might have + 过去分词”, 意为“可能 / 大概已做了某事”。

13. 把may改为can / could。根据句意, 表示对过去情况的猜测, 用于疑问句应用“can /could have + 过去分词”, 意为“可能 / 也许已做了某事”, 而“may /might have + 过去分词”表示对过去情况的一种不太有把握的可能性推测, 只能用于肯定句或否定句。

14. 把mustn't改为hasn't。“must have + 过去分词”表示对过去已发生动作的推测, 如果句中没有表示过去的时间状语, 反意疑问句应用“hasn't/ haven't sb”, 主语“Harry”是第三人称单数, 故用“hasn't he”。

15. 把第二个need改为must。问句“—Need I...?”的回答语要用must, 表示“必须”。

( 三) 1. Should。根据句意, should 可以用于较强语气的假设情形中, 表示“万一”。从句是省略if的虚拟条件句, 从句需用倒装。

2. can / could have injured。根据句意, 表示过去玛丽本来可能会严重受伤, 但实际上没有, 所以用“can /could have + 过去分词”, 意为“过去本来能够做某事而实际上没有做”。

3. would have arrived。根据句意可知, 表示“过去本来会干某事而实际上没有做到”, 所以用“would have + 过去分词”。

4. must have lost。根据句意可知, 我一定减肥了这一动作发生在过去, 用于肯定句, 表示“过去一定做过某事”, 是一种很有把握的推测, 所以用“must have + 过去分词”。

5. can't / couldn't have written。根据句意, 表示对过去发生的事很有把握的否定推测, 所以用“can't/couldn't have + 过去分词”, 意为“过去不可能已做了某事”。

6. should / ought to have done。根据句意, 表示过去本应该做某事而实际上没有做到, 含有责备或遗憾的语气, 所以用“should /ought to have + 过去分词”。

7. may / might have read。根据句意, 表示过去可能做过某事, 是对过去情况的一种不太有把握的可能性推测, 所以用“may /might have +过去分词”, 意为“可能/大概已做了某事”。

8. Shall。根据句意, shall用于第一、三人称的疑问句时, 表示说话人征询对方的意见或提出请求。

9. won't。根据句意, 表示意志或意愿, 所以用 will, 句意为否定, 故用 won't。

10. should。根据句意, 表示惊讶, 意为“竟然”, 所以用 should。

11. Need。need 意为“需要”, 用作情态动词, 仅用于否定句、疑问句或条件句中, 符合本句句意与语境。

12. oughtn't to / shouldn't have left。根据句意, 表示某种行为不该发生但却发生了, 所以用“should not/ought not to have + 过去分词”。

13. doing / to be done。句子的主语“morework”是动作承受者时, need在句中作行为动词, 所以need后接动词-ing形式或后接不定式的被动形式充当宾语。

14. dare not / daren't / dared not ( to) / didn't dare ( to) 。dare用作情态动词, 主要用于疑问句、否定句和条件从句中, 一般不用于肯定句中。dare作行为动词, 有时态、人称和数的变化, 在肯定句中, 通常dare后接带to的不定式;在否定句和疑问句中, dare后可接带to或不带to的不定式。根据句意, dare用作情态动词用于否定句, 所以此空 用dare not或缩写为daren't; dare用作实义动词用于否定句, dare后可接带to或不带to的不定式, 根据句中的时间状语“that night”可知, 此句还可用一般过去时, 所以此空还 可用dared not ( to) / didn't dare ( to) 。

15. shan't / shall not。根据句意, 表示说话人给对方的警告, 用于第二、三人称的陈述句, 所以用shall。

二、情态动词表示推测的考查

对情态动词表示推测的用法，是高考考查情态动词的一个重要方面。例如：

1. Sorry, I’m late. I______have turned off the alarm clock and gone back to sleep again . (NMET 2000春季北京， 20)

A. might B. should C. can D. will

3.Mr Bush is on time for everything. How______it be that he was late for the opening ceremony?（2001年春季上海，23）

A. canB. shouldC. mayD. must

A. may not beB. won’t be

C. couldn’t beD. mustn’t be

解析：may not be : 可能不是；won’t be：不会是；couldn’t be：不可能是； mustn’t be ：一定不是。根据提供情境there was little snow 说明山里滑雪是件不可能的事，may not 语气不如couldn’t强。答案是：C。

5.Is John coming by train ?

—He should, but he______not .He likes driving his car.(NMET 2002,25)

A. mustB. can C. need D. may

解析：根据提供的情境he likes driving his car，他可能不坐火车来;can not:不可能，语气太强。所以应选：D。

6.My English-Chinese dictionary has disappeared . Who______have taken it?(2003年春季上海，24)

A. shouldB. must C. couldD. would

解析：could have done 表示对过去情况的推断，“可能是谁把它拿走了”。答案是：C。

7.You might just as well tell the manufacturer that male customers______not like the design of the furniture. (2004 年春季上海29)

A. must B. shallC. mayD. need

解析：may：可能，表示猜测。 由主句中might可判断男顾客可能不喜欢家具的设计是一种猜测。答案是： C。

8.You______be tired ——you’ve only been working for an hour. (NMET2004 年全国卷III 29)

A. must not B. won’t C. can’t D. may not

解析：must not:一定不；won’t：不会；can’t：不可能；may not：可能不。根据提供的情境“仅仅工作了一个小时”，所以用can’t be tired 表示推断，不可能累。答案是：C。

9.Tom graduated from college at a very young age.

—Oh, he______have been a very smart boy then. (NMET2004年全国卷IV ，22)

A. could B. should C. mightD. must

解析：由前一句可判断，Tom过去肯定是个很聪明的孩子。答案是:D。

10. There’s no light on.

—They ________be at home .（NMET2006 全国卷I，24）

A. can’t B. mustn’t C. needn’t D. shouldn’t

解析:can’t：不可能 ；mustn’t：一定没，不表示推测; needn’t :不必要，不表示推测；shouldn’t：不应该，语气比can’t弱。句意为：没有亮灯——他们不可能在家。答案是：A。

分析：高考对表示推测的情态动词集中在must, can, could, may, might上，准确掌握它们使用的场合，是解决问题的关键。Must 用于肯定陈述句，表示肯定推测；can, could用于疑问或否定陈述句，表示可能性推测；may, might用于陈述句，表示可能性推测；用于否定陈述句中，can’t （不可能）的语气比may not（可能不）强。此外，还要注意有对过去和对现在两种情况的推测,对过去推测用情态动词+have done ，对现在推测用情态动词+ 动词原形。

三、情态动词表示虚拟的考查

情态动词＋have+过去分词表示与过去事实上相反的情况，也是高考单项选择题涉及到情态动词的一个重要方面。

1. There was a lot of fun at yesterday’s party. You______come, but why didn’t you?(1999年上海， 14)

A. must have B. should

C. need have D. ought to have

解析：ought to have done 表示本来应该做某事而实际没做，should do 表示现在应该做某事，与题中 at yesterday’s party 表示的时间不一致。所以选D。

2.I was really anxious about you. You______home without a word.(NMET2001,33)

A. mustn’t leaveB. shouldn’t have left

C. couldn’t have leftD. needn’t leave

解析：shouldn’t have done 表示本来不应该做而实际上做了。句意为：你不应该不说一句话就离开家，而实际上是没说一句话就离开家了。答案是：B。

3.Oh, I’m not feeling well in the stomach. I______so much fried chicken just now.(2002年春季上海，28)

A. shouldn’t eat B. mustn’t have eaten

C. shouldn’t have eaten D. mustn’t eat

解析：该句所表达的意思是刚才我不因该吃那么多炸鸡，而实际上是吃了那么多，可以判断用shouldn’t have eaten. 答案是 C。

4.I’ll tell Mary about her new job tomorrow.

—You______her last week.（NMET2004年福建，32）

A. ought to tell B. would have told

C. must tellD. should have told

解析：根据句意你本应该上周告诉她，而实际上你明天才告诉，有埋怨之意.应用should have told.答案为D。

5.Mr White______at 8:30 for the meeting ,but he didn’t show up. （NMET2004年全国卷I，27）

A. should have arrived B. should arrive

C. should have had arrivedC. should be arriving

解析：据提供的语境but he didn’t show up说明他本来应该在8:30来开会，而实际上没来，可判断用should have arrived .答案是：A。

分析：高考对情态动词表示虚拟的用法，表示与过去事实相反的情况。近几年高考，主要侧重should （not）have done 这一句式上，表示本来不该做却做了或本来该做却未做的事，在复习时，还应关注其它几种虚拟形式，如need (not)have done 表示本来需要做而未做或本来不需要而做的事等等，以做到有备无患。

高考命题趋向：近十年高考试题，对情态动词的考查涉及到基本含义、表示推测、表示虚拟这三个方面，考查的比较全面，突出的一点是重视在具体语境下的灵活使用。情态动词和助动词都帮助实义动词构成谓语，近两年又趋向于情态动词与助动词混合考查，增大了此类试题的难度，这一点应引起广大考生注意。例如：

1.Tom ,you didn’t come to the party last night?

—I______, but I suddenly remembered I had homework to do .(NMET2007全国卷II，20)

A. had to B. didn’tC. was going to D. wouldn’t

解析：had to:不得不；didn’t:没来；was going to：打算来；wouldn’t:不愿来。句意：——汤姆，昨晚你没来参加舞会吗？——我本打算来，但我突然记起有作业要做。But是关键词，所以答案是：C。

2.Your phone number again? I______quite catch it .

—It’s86184867.

A. didn’t B. couldn’t C. don’t D. can’t

解析：记住电话号码并非难事，未完全听清楚电话号码并非能力的事，此处只是说没有完全听清楚电话号码，所以，应选A。

即学即练：

1.John has made a great progress in English. He______very hard recently.

A. must be B. may work

情态动词考点探析 篇7

一、考查情态动词的基本意义和特殊用法

一些常见情态动词的基本意义以及特殊用法往往是高考考查的重点,考生应确切理解其含义并根据句子意思使用恰当的情态动词。

1. must和need

must表示“必须”的意思,含有说话人主观上的看法和态度;need作情态动词表示“必要,必须”,通常用于否定句和疑问句,不能用于肯定句。

【典例1】I love the weekend,because I_____get up early on Saturdays and Sundays.(2016年北京卷)

解析:neednt。根据句子的因果关系可知,此处表示“不需要”应使用neednt。

【典例2】—Cant you stay a little longer?(2015年北京卷)

—Its getting late.I really_____go now.My daughter is home alone.

解析:must。此处表示个人的主观意愿,意思是“我现在必须要走了”,应使用must。

另外,must用于疑问句,表示责备、抱怨的感情色彩,意思为“偏要,硬要”;而mustnt则表示“禁止,不允许”,是说话人强有力的劝告。

【典例】—_____you interrupt now?Cant you see Im on the phone?

—Sorry Sir,but its urgent.

解析:Must。根据对话的语境可知,此处表示“责备,抱怨”的感情,应使用must,意思是“你一定(非得)要……吗?”。

2.can和could

两者都用来表示能力,意为“能够,会”,也用来表示许可(常用在口语中)或表示怀疑、惊异、不相信等态度(常用于否定句,疑问句或感叹句中)。could表示过去,也可以表示语气的委婉。

【典例1】Itwasreallyannoying;I______get access to the data bank you had recommended.(2016年天津卷)

解析:couldnt。根据句意可知,此处表示“不能”进入数据库,并且前面句子中的动词用的是过去时,故应使用couldnt。

【典例2】Although you_____find bargains in London,its not generally a cheap place to shop.(2014年全国大纲卷)

解析:can。根据句意可知,此处表示“能够”,且后面的句子使用的是一般现在时,故应使用can。

3.shall和should

shall用于第一、第三人称疑问句表示征求对方意见;用于第二、第三人称肯定句或否定句表示说话人给对方的“禁止、命令、警告、允诺或威胁等”。

should用来表示建议、责任、义务时,意为“应该,应当”,此时可用ought to替换;也可用来表示惊讶、赞叹等情绪,意为“竟然”。另外,should还可以表示按常理进行的推测,意为“按理应当”。

【典例1】One of our rules is that every student______wear school uniform while at school.

解析:shall。根据句意可知,此处表示学校的规定,学生在校应穿校服,具有强制、命令的感情色彩,故应使用shall。

【典例2】It was sad to me that they,so poor themselves,______bring me food.(2014年江苏卷)

解析:should。此处表示惊讶,用should,意思是“竟然”。

4.may和might

表示允许、许可以及表示推测时,两者都可用,只是might表示的语气较委婉或推测的语气更弱。

【典例1】You_____feel all the training a waste of time,but Im a hundred percent sure later youll be grateful you did it.(2015年陕西卷)

解析:may。根据句意,此处表示可能性比较大的推测,应使用may,意思是“可能,或许”。

【典例2】Life is unpredictable;even the poorest_____become the richest.(2014年江西卷)

解析:might。此处表示推测,但可能性小,故应使用might。

二、考查情态动词表推测的用法

1. 对现在或将来的推测用“情态动词+动词原形”。

肯定的推测一般用must,may,might。其中,must的语气最强,意为“肯定”“准是”“想必是”;may的语气次之,意为“很可能”,might语气最弱,意为“有时会”“也许”“可能”。

否定推测分为两种情况:语气不很肯定时,常用may/might/could not,意思是“可能不”“也许不”;否定语气较强时,则用cant,意思是“根本不可能”“想必不会”,表示惊异、怀疑的感情色彩。

【典例1】You_____be Carol.You havent changed a bit after all these years.(2015年重庆卷)

解析:must。由后面的“这些年你一点没变”可知,此处表示十分肯定的推测,应使用must。

【典例2】It_____be the postman at the door.It’s only six oclock.

解析:cant。由后面一句“才刚刚六点钟”可反推前面句子中门口的“肯定不是”邮递员,故填cant。

2.对过去发生事情的推测,用“情态动词+have done”。

对过去发生事情的肯定推测用“must/may/might+have done”;否定推测用“can/may/might not+have done”;疑问推测用“Can...have done?”。

【典例1】George______(go)too far.His coffee is still warm.(2016年浙江卷)

解析:cant have gone。由后面的“他的咖啡仍然是温的”可推知“乔治根本不可能走得太远”。此处表示对过去的否定推测应使用cant have done。

【典例2】Jack described his father,who______(be)a brave boy many years ago,as a strong-willed man.

解析:must have been。此处表示对过去的肯定推测,应使用must have done,故填must have been。

【典例3】My MP4 player isnt in my bag.Where______I have put it?

解析:can。此处表示对过去发生事情的疑问推测,应使用“Can...have done?”,故填can。

三、考查“情态动词+have done”表示虚拟的用法

1.“should+have done”表示本应该做某事而实际上没有做。

其否定式表示某种行为不该发生但却发生了。

【典例1】—Sorry,Mum!I failed the job interview again.(2015年福建卷)

—Oh,its too bad.You_____have made full preparations.

解析:should。根据对话语境可知,表示对过去发生的事情的后悔遗憾应使用should have done,表示本应该做,而实际未做。

【典例2】I_______have watched that movie—it’ll give me horrible dreams.

解析:shouldnt。表示“本来不应该做而做了某事”用shouldnt have done,故填shouldnt。

2.“would+have done”表示本来愿意做某事而实际上没有做。

其否定式表示本不愿意做而做了。

【典例】People are recycling many things which they______(throw)away in the past.(2014年安徽卷)

解析:would have thrown。表示过去本来会做而没有做的事情,用would have done。

3.“could+have done”表示本来能够做成某事,但结果却没能做成,含有遗憾的意味。

【典例】We______(face)the difficulty together,but why didn’t you tell me?

解析:could have faced。表示对过去本来能够做而未做某事的后悔或遗憾,应使用could have done形式。

4.“neednt+have done”表示本来不必做某事而实际上做了某事。

【典例】I______have worried before I came to the new school,for my classmates here are very friendly to me.(2015年天津卷)

解析:neednt。表示本没有必要做某事而实际上做了用needn’t have done。

8. would。would表示“总是,老是”,此处和not连用,意思是“老是不,总是不”。

9. neednt。根据对话的语境可知,此处表示“不需要”带任何东西,故填neednt。

1 0. shall。shall用于第二、第三人称表示“允诺”。

1 1. should。表示吃惊的语气,意思是“竟然”。

25.neednt。根据后面的语境,提前半个小时到达,说明Mark本来不必那么匆忙,所以用neednt have done结构,表示“本来不必要做某事而实际上做了”。

(二)语法填空

【主旨大意】本文为说明文,题材为社会文化类,介绍了“自拍(selfie)”这个词的由来以及自拍流行的原因。

1.was named。本句中缺少谓语动词,所以括号中给出的动词应使用谓语动词形式。根据it和name的被动关系,再结合时间状语in 2013,可知本空应使用一般过去时的被动语态。

2.taken。本句中已有谓语动词is,括号中给出的动词take应使用非谓语动词形式。根据take与其逻辑主语photo之间的被动关系可知,应使用过去分词。

3.using。本句中已有谓语动词take,括号中给出的动词use应使用非谓语动词形式。根据use与其逻辑主语people之间的主动关系可知,应填using表示方式。

4.to。根据固定搭配解题。from…to...是固定搭配,意思是“从……到……”。

5.makes。本句中缺少谓语动词,所以括号中给出的动词make应使用谓语动词形式。本文的主体时态使用了一般现在时,再结合主谓一致,应填谓语动词的单数形式。

6.can。根据句意可知,自拍能够帮助人们记住发生在他们身上的事情,因此填can。

7.which。关系代词which指代先行词a photo of myself,引导非限制性定语从句,并在从句中作save的宾语。

8.personal。空格处所填单词在句中修饰名词life,需填person的形容词形式。

9.to ask。考查too…to...结构,意思是“太……而不能……”。
