情态动词+被动语态
高中英语情态动词的用法一．can和could
情态动词用法例句
can/could 表示能力
1．“I don’t think Mike can type.”
“Yes, he can.”
2．I can speak fluent English now , but I couldn’t last year. 在肯定句中，表示客观可能
性，并不涉及具体某事会发
生，常用来说明人或事物的
特征（译为“有时会”）。要表
达具体某事实际发生的可能
性时，不用can，需用could，
may，might。
1．As a human being, anyone can make a mistake.
2．I’m confident that a solution can be found.
3．He can be very forgetful sometimes.
4．I may stay at home this weekend.（实际可能性）
5．Peter might come to join us.(实际可能性)
6．It will be sunny in the daytime ,but it could rain
tonight.(实际可能性)
表示请求和允许。表示请求，
口语中常用could代替can，
使语气更委婉。
1．Can we turn the air conditioner on?
2．Any police officer can insist on seeing a driver’s license.
3．In soccer, you can’t touch the ball with your hands.
4．Could you have her call me back when she gets home,
please?
5．I wonder if I could just ask you to sign this.
表示对现在的动作或状态进
行主观的猜测，主要用在否
定句和疑问句中。
1．It can’t be easy caring for a man and a child who are not
your own.
2．Can the man over there be our head master?
表示惊异、怀疑、不相信等态度，主要用在否定句、疑问句和感叹句中。1．Can this be an excuse for not giving them help? 2．This can’t be true.
3．How can you be so crazy.
特别说明：
（1）could用来表示请求时，语气委婉，主要用于疑问句，不能用于肯定句，答语应用can（即：could不能用于现在时态的简略答语中）。如：
——Could I use your dictionary?
——Yes, you can.(否定回答可用：No, I’m afraid not.或者是you can’t)
表示推测时，could不是过去式，只是语气更委婉；若是推测已发生的事或过去的情况，用can/could have done (2)can和be able to辨析
can(could)和be able to都可以表示能力，意思上没有区别。但can只有现在式和过去式，而be able to则有更多的形式。如：
I’ve always wanted to able to speak fluent English.
Those bags look really heavy, are you sure you’ll be able to carry them on your own?
但是，表示在过去某时的某一场合经过一番努力，终于做成了某事，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 do或succeed in doing。如：
After the accident it was a long time before she was able to walk again.
The fire was very big, but most people were able to escape from the building.
(3) 惯用形式“cannot …too…”表示“无论怎么……也不（过分）”。如：
You cannot be too careful.你越小心越好。
惯用形式“cannot but+ 不定式（不带to）”表示“不得不，只好”。如：
I cannot but admire her determination.我不得不钦佩你的决心。二．may和might
情态动词用法例句
may/might 表示允许、许可。否定回答一般用must
not/mustn’t,表示“禁止、阻止”之意，但也可以用
had better not (最好别)或may not（不可以），语
气较为委婉。
1．May I come in and wait?
2．——May I smoke here?
——No, you mustn’t(或No, you’d better not.)
在表示请求、允许时，might比may语气更委婉
些。用May I征询对方许可在文体上比较正式，
在口气上比较客气，在日常用语中，用Can I征
询对方意见更为常见。
1．Might I borrow your pen?
2．I wonder if I might speak to your son.
表示可能性的推测，通常用在肯定句和否定句中，
含有“或许”“大概”“可能”之意；用might代替may
时，则语气显得更加不肯定。
1．It may rain this afternoon.
2．She might come to join us this afternoon.
3．I suppose he might have missed the train.
may用于祈使句表示祝愿
1．May you succeed.
2．May you live happily!
3．May she rest in peace.愿她安息。
惯用句式：
“may as well或might(just)as well+动词原形”意
为“最好，满可以，倒不如”，相当于“had better或
there is no reason to do anything else.
1．There is nothing to do, so I may as well go to
bed.
2．You may as well tell us now, we’ll find out sooner
or later.
3．I suppose we might as well go home.
4．And if you have to plough the field anyway, you
might as well plant it at the same time. 二．must和have to
情态动词用法例句
must 表示“必须，应该”之意，语气比should，ought to
强烈。其否定形式mustn’t表示“不准，不应该，禁
止”等意
1．You must come to school on time.
2．Everybody must obey the law.
3．You mustn’t drive so fast in the street.
4．We mustn’t waste any more time.
在回答带有must的问句时，否定回答常用needn’t
或don’t have to，表示“不必”，而不用mustn’t
1．—Must I come back before ten?
—Yes，you must.
----No, you needn’t(No, you don’t have to) 表示有把握的推测，意为“一定、准是、相必”，只
用于肯定句中
1．It must be my mother.
2．You must be hungry after a walk.
3．There must be a hole in the wall.
have to “必须，不得不”，意义与must相近。但must表示的是说话人的主观看法，而have to则往往强调客
观需要。1．The film is not interesting. I really must go now. 2．I have to go now, because my mother is in hospital.
must只有一种形式，即现在式与过去式都是一种形式，而have to则涉及各种人称、时态等方面的变化形式。1．I had to work hard when I was your age.
2．I will have to learn how to use a computer. 3．In order to take the exam, we’ll have to finish the whole book by the end of this month .
两者的否定意义不同，mustn’t表示“禁止，不许”，1．You mustn’t go there.
don’t have to表示不必。2．You don’t have to go there. 注意：表示”偏要，硬要做某事
-how old are you, madam?
-if you must know, I’m twice my son’s age(如果你非得知道，是我儿子年龄的两倍)
四．shall和should
情态动词用法例句
shall 用于第一、三人称构成的疑问句，表示征求对方意见或请求指示,其意为“要不要”、“…好吗”：1．Shall I open the window? 2．Shall we say 6 o’clock, then? 3．Shall he come to see you?
1 用于第二、三人称陈述句中，表示说话人给对方的命令、警告、允诺、威胁、命令、规定、必然性等
2表示强制，用于法令、条约、规章中，意为“必须，应该”。1．Don’t worry, you shall get the answer this afternoon.(允诺)
2．He shall be sorry for it one day, I tell you. （警告）
3．You shall do as I say. (命令)
4．If you children don’t do as I tell you, you shall not go to the party. (威胁)
5．The Persons under 18 shall not be employed in night work．不满十八岁的人不得雇佣干夜间工作。(表规定)
6．That day shall come(表必然性) 7．Candidates shall remain in their seats until all the papers have been collected. 试卷完全收回
后，应试人才能离开座位。
should 表示劝告或建议，意为“应该”1．What should I do?
2．Should I trust him?
3．You should read his new book.
表示推测，用在肯定句中，对现在的情况或可能发生的事的主观推测或期待。意为“想必，大概，或许”。
【注】should表示推断时，语气较肯定，通常是指非常可能的事(因为暗示有一定的事实依据或合乎常理)，而may, might, could等表示推测时，则语气较不肯定，尤其是might, could。1．It should be a nice day tomorrow.
2．It ‘s nearly 7 o’clock .Jack should speak in such a way.
3．He should be around sixty years old.
还可以用在if引导的条件句中，表示一件事听起来可能性很小，但也不是完全不可能，相当于“万一”的意思。从句谓语用should+动词原形构成，主句都一定用虚拟语气1．Ask Tom to ring me up if you should see him.
(你万一见到汤姆，请让他给我打个电话) 2．Should I be free tomorrow, I’ll come. (万一我明天有时间，我就过来)
3．If things should change suddenly, please let me know. (万一情况突变，请通知我)
1should表示意外或惊讶
2用于疑问句或感叹句中，表示意外、惊异的情绪，意为“竟会”，与why，what，how，who连用，如果是疑问句，则不需要回答。1．It’s strange that he should come so late. 他竟然来这么迟真是奇怪。
2．I’m sorry that this should have happened. 我很遗憾竟然发生这种事。
3．I’m surprised that he should say so. 他竟这样
说，这使我很惊讶。
4．Why should anyone want to marry Tony?
5．Don’t ask me. How should I know? 五．will和would
情态动词用法例句
will/would 用于表示意志或意愿或决心。will指现在，
would指过去。1．He is the man who will go his own way. (他首歌自行其是的人。)
2．They said they would meet us at 10:30 at the station.
表示请求、建议等和you连用，用would 比用will委婉、客气。1．Will you please take a message for him? 2．Would you please tell me your telephone number?
表示习惯或倾向，意为“总是，惯于”。will 至现在，would指过去。1．Fish will die without water.
2．People will talk. (人们总会说闲话。)
3．When we worked in the same office, we would often have coffee together.
表示推测，意为“很可能，大概”。will表示推测比should把握大，比must把握小。1．These things will happen.
2．That will be the messenger ringing.
3．It would be about ten o’clock when he left home.
表示功能，意为“能，行”。惯用形式：will do/would do表示“解决问题”、“就行”。1．That will be all right.
2．Either pen will do.
3．It would not do to work too late.（工作太晚不行。）
用于否定句中，意为“不肯”、“不乐意”1．I won’t listen to your nonsense.
2．No matter what I said, he wouldn’t listen to me.
特别说明：would与used to辨析
would可用来表示过去反复出现的动作，但不能表示过去存在的状态，所以我们不能说：“she would be a quiet girl.”另外，would强调过去某种特定情况下的活动，是完全过去的事情，同现在没有联系。而used to则着眼于过去和现在的对比，隐含现在已不存在，动作或状态都可表示。Would可以表示不规则的习惯，used to则不可。如：He used to be a naughty boy and cause trouble.
I used to get up at six in the morning.
Sometimes she would take a walk in the neighboring woods.
In those days, whenever I had difficulties, I would go to Mr. Chen for help.
六．need和dare
情态动词用法例句
need 用于表示“需要，必要”之意。做情态动词时，仅
用于否定句和疑问句，只有现在时，过去式要
用needn't have，疑问式用need+人称?,否定式
用need not(即needn't），
1．—Need we leave soon?
—Yes, you must.(No, you needn't, or don’t have to)
2．You needn't have hurried.
(=It was not necessary for you to hurry，but you did).
你当时不必这么匆忙。
做实义动词时，其变化与一般的实义动词相同，
后接带to的不定式（need doing = need to be
done ）,过去式用needed、did you need?和
didn't need,肯定式用needs/needed/need,疑问
式用do、does、did提问，否定式要在前面加
1. A job like nursing needs patience and
understanding.(need+名词，need
understanding=need to be understood,需要被理解)
2．He needs to see a doctor.(need to do)
3．Do you still need volunteers to help clean up after
don't、doesn't、didn't the party?(need somebody to do something)
4．They didn't need to start so early.(do not need to do)
dare 用于表示“敢于”之意。做情态动词，没有人称和数的变化，主要用于否定句、疑问句和条件状
语从句中1．—Dare you tell her the truth?
—Yes, I dare. /No, I daren’t. 3．How dare you accuse me of lying! 4．He daren’t admit this.
用作实义动词时，其变化与一般的实义动词相同。在肯定句中，dare后接带to的不定式；否定句中，dare后既可接带to的不定式，也可接不带to的不定式。1．Only a few journalists dared to cover the story. 2．He doesn’t dare (to) go there alone. 3．Don’t you dare (to) touch it?
七．ought的用法：
情态动词用法例句
ought to do 表示“应该”之意1．You ought to take care of him.
2．—Ought I go now?
—Yes, you ought to. /No, you oughtn’t to. 表示推测。注意与must表示推测是的区别1．He must be home by now. (断定他已到家)
2．He ought to be home by now. (不十分肯定)
3．This is where the oil must be. (比较直率)
4．This is where the oil ought to be. (比较含蓄)
说明：should与ought to 表示“应该”时的区别
should 表示自己的主观看法，而ought to的语气中，含有“按道理应该……”之意。若要反映客观情况或涉及法律义务和规定，一般用ought to。如：
You should help them with their work.
You are his father. You ought to get him to receive good education.
八．“情态动词+have done”用法
情态动词+have done 用法例句
must have done 表示主观上对过去已经发生的行为进行
推测，意为“想必，准是，一定做了某事”1．She must have gone through a lot.
2．He must have visited the White House during his stay in the United States.
may/might have done 表示对过去已发生行为的推测，意为“也
许/或许已经（没有）……“。一般用于肯
定句或否定句中，不用于疑问句。用might
则表示语气更加不肯定。1．You may have learnt the news. 2．He may not have heard his name called.
3．Sorry I’m late. I might have turned off the alarm clock and gone back to sleep again.
can…have done cannot have done 表示对过去发生的行为的怀疑和不肯定，
通常用在否定句和疑问句中。（can换成
could时语气委婉）
1．Where can she have gone?
2．Could he have done such a
foolish thing?
3．The boy can’t have finished
reading the book so soon

情态动词被动语态
Teenagers should be allowed to choose their own clothes 含情态动词的被动语态 含情态动词的被动语态是情态动词和被动语态中的重要内容，也是中考的重要考点，学习时应注意以下三点： 一、理解含情态动词的被动语态的概念 含情态动词的被动语态说明某个被动性动作所反映出的感情和态度。初中阶段可用于被动语态的情态动词有can，may，must，need，should等，分别表示“能够被……”，“可以被……”，“必须被……”，“需要被……”，“应该被……”等。 二、掌握含情态动词的被动语态的不同句式的变换方法 含情态动词的被动语态的疑问句、否定句的变化均借助于情态动词完成。 （一）一般疑问句 直接将陈述句被动语态中的情态动词提前。如： Must this work be done at once? 这项工作必须立即完成吗？ Should your homework be finished before six? 你的家庭作业应在六点前完成吗？ （二）特殊疑问句 由疑问词加上一般疑问句被动语态构成。如： When must this work be done? 这工作必须在什么时候完成？ Where can the lost book be found? 这本失踪的书能在什么地方被找到？ （三）反意疑问句 借助情态动词构成附加疑问部分。如： This bridge can be built next year, can’t it? 这座桥明年能建成，是吗？ This book shouldn’t be taken out of the library, should it? 这本书不应被带出图书馆，是吗？（四）否定句 在情态动词后面加上not或never即可，但must表“必要”时否定式为needn’t。如： This work needn’t be done at once. 这项工作没必要立即做。 This dustbin shouldn’t be put here. 这个垃圾箱不应放在这儿。 三、含情态动词的被动语态的一般疑问句的回答 含情态动词的被动语态的一般疑问句的回答应保留原情态动词，但must表“必须”时，其否定回答应用needn’t，need表“必要”时，其肯定回答应用must。如：

被动语态以及情态动词构成及用法详解
被动语态用法详解 TENSE 主动语态被动语态 一般现在时be+V.\V.s am\is\are+V (p.p) 一般将来时will\be going to\be (about)to+V. will be +V(p.p) 现在进行时am\is\are+V.ing am\is\are+b eing+V(p.p) 一般过去时①was\were②V.ed was\were+V( p.p) 现在完成时have\has+V.p.p have\has+be en+V(p.p) 过去完成时had+V.p.p had+been+V( p.p) 过去进行时was\were+V.ing was\were+be
ing+V(p.p) 情态动词情态动词+V. 情态动词+be+V(p.p) 被动语态牢记一点， be加动词过去分词。分析句中主和谓，承受者作主语即被动。 短语动词不可忘介、副词。另有不及物动词，只有主动无被动。还要注意其时态， 与主动语态全相同。 不用被动语态的情况 1）不及物动词或动词短语无被动语态（即多数的瞬间动词）：appear, die（死亡）,disappear（消失）, end (vi. 结束）, fail, happen, last, lie, remain, sit, spread, stand break out, come true, fall asleep, keep silence, lose heart, take place. After the fire, very little remained of my house. 比较： rise, fall, happen 是不及物动词；raise, seat是及物动词。 （错）The accident was happened last week. （对）The accident happened last week. 要想正确地使用被动语态，就须注意哪些动词是及物的，哪些是不及物的。特别是一词多义的动词往往有两种用法。解决这一问题唯有在学习过程中多留意积累。 2）不能用于被动语态的及物动词或动词短语：fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to This key just fits the lock. 3）系动词无被动语态（“keep”除外）：appear, be become, fall, feel, get, grow, look, remain, seem, smell, sound, stay, taste, turn It sounds good. 4）带同源宾语的及物动词，反身代词，相互代词，不能用于被动语态： die, death, dream, live, life She dreamed a bad dream last night. 5）当宾语是不定式时，很少用于被动语态。 （对）She likes to swim. （错）To swim is liked by her. 有些动词可以带双宾语在用于被动结构时，有些动词可以带双宾语。在这种情况下，主动结构中的间接宾语变为主语时，直接宾语仍然保留在谓语后面；直接宾语变为主语时，间接宾语前通常加上介词for/to, etc.。即：S+V+IO+DO→IO+ be done +DO→DO+ be done + prep. +IO We often hear him play guitar. He is often heard to[1]play guitar. →It is often heard from him to play guitar. 新被动语态 Get+过去分词也可以构成被动语态，用这种结构的句子侧重于动作的结果而不是动作本

情态动词详解与被动语态句式结构
