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,主要有下列:
can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) .
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, 情态动词则在主语之前。
情态动词的特点:
情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。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。
情态动词的用法:
can (could) 表示说话人能,可以,同意,准许,以及
客观条件许可,could 为can 的过去式。
Must 必须,应该,一定,准是, 表示说话人认为有必要做某事, 命令, 要求别人做某事以及对事物的推测。
must 用来指一般现在时和一般将来时, 过去式可用have to 的过去式代替。
must + have + 过去分词,表示现在对过去事物的推测。must 和have to 的区别: must 表示说话人的主观思想, have to 表示客观需要。
need 是一个情态动词, 他的用法完全和其他情态动词一样, 但need 还可当作实义动词使用, 这时need 就象其他动
词一样,有第三人称,单复数, 后面加带to 的动词等特性。needn't + have + 过去分词表示过去做了没必要做的事情。dare 除用作情态动词外,更多的是当实义动词使用, 用法同实义动词一样,要考虑人称,单复数,时态等。
ought 应当,应该后面跟带有to 的动词不定式。
ought + to have done 句型。指过去动作,表示一件事情该做而未做。
ought not to have done 句型。表示一件不该做的事情却做了。
will (would)决心,愿望。would 为will 的过去式,
will, would用于疑问句表示说话人向对方提出请求或询问,用would 比will 更婉转,客气。
Shall, should表示命令,警告,允诺,征求,劝告,建议惊奇。have to,不得不,必须,表示客观条件只能如此, 而must 则表示主观思想必须
追问
情态动词的用法
情态动词的特征：
1）各个情态动词自身都有一定的词义。
2）情态动词不能在句中独立担当谓语，必须和另一动词一起构成谓语。
3）情态动词在句中不受任何人称,性,数变化的影响。
4) 情态动词后接的不定式（除ought外）都不带to ，即接动词原形。
英文中的情态动词主要有：can , could ; may , might ; must ; ought ; need ; dare , dared ，另外，shall , will , should , would在一定的场合也可用作情态动词。例如：
1.常用情态动词的基本用法
（一）can , could
1）表示能力
I can afford to buy the car. 我能买得起这辆小汽车。
She can sing that song in English. 她能用英文唱那歌。
I could not understand the lecture given by Mr. Smith . 我听不懂史密斯先生作的那个讲座。
特别提示：be able to和 can同义，但前者可以用于更多时态。
如：The baby has been able to walk.
They will be able to speak fluent English.
2) 表示允许（在口语中可以和may换用）
You can go there with me.
Can I come in ?
They said we could start off then.
3)表示可能性
Such things can never happen again. 这样的事情决不会再发生。
A more suitable person than him for the job can not be found .
不可能找到比他更适合这份工
作的人了。
4）（用于否定句、疑问句或感叹句中）表示惊异、不相信等。
How can / could you be here ? 你怎么会在这儿？
She couldn't / can't be so stupid to do that .
她不可能蠢得去做那种事吧。
He couldn't / can't be over seventy .他不可能有七十多岁了。
Where could / can the boy be now ? 那孩子现在能在哪儿呢？5）另外，could还常用于表示较客气委婉的看法、提问及用于虚拟语气的结构中。这时候，could就不可以看作是can的过去式了。而是could自己独特的用法。如：
Could you speak a little slowly ? 您能稍微说慢一点儿吗？
We would appreciate it if you could offer us any help .
如果您能为我们提供帮助的话，我们将不甚感激。
You could have done better if you had worked harder at it . 如果你再加把劲，本来可以干得更好一些的。
二）may , might或许，可能，可以
1）表示允许
口语中，在表示允许或征求意见时，can与may可以换用。
May／Can I come in ? 我可以进来吗？
Can/May I help you ?
You may watch TV at the weekend.
特别提示：对May…？的问句肯定回答时常用Certainly ./Sure. / Yes, please.否定回答时常用No , …mustn’t. (语气较重）Please don’t.（语气较轻）
May I use your desk when you are not here?
Yes , please. / No , you mustn’t.
2）表示推测、可能。
I may be busy from tomorrow on .从明天起我可能会忙起来。
I wondered if they might agree with the idea .我想知道他们是否会同意这种想法。
3) might是 may的过去式。用于一般现在时，同样可以表示允许或可能，但语气要委婉些。
Might (May ) I have one of your pictures.
You might (may ) have a temperature.
4) may间或用来表示祝愿，也常用于表示目的或让步的状语从句中:
May that day come soon . 但愿这天早日到来。
May you succeed in winning the first prize in the game . 祝愿你比赛夺冠成功。
5) might也常用于表示目的等状语从句中，或用于虚拟语气的结构中:
They left off earlier on that day so that they might catch the first train .
那天，他们为了赶上头班车动身早一些。
He died so that the others might live .
为了其他的人能活下去，他自己牺牲了。
三）must应该，必须，一定
1) must 可表示“必须”或“应该”的意思，它通常表达说话者的主观意志。must not是其否定形式，表示“不应该”、“不允许”“禁止”，语气比较强烈。must没有过去式。
(have to却表示由于某种客观原因而不得不做某事。除此以外，have to自身有时态的变化形式。如：
Jenny had to tidy up the room before her mother came back .
珍尼不得不在她妈妈回家以前将房间整理好。
We'll have to reconsider the whole thing . 我们将不得不重新考虑整个事情。)
You must not speak ill of others . 你一定不要说别人的坏话。
Cars must not parked here . 这里禁止停车。Smoking must not allowed in the office . 严禁在办公室吸烟。
注意：回答以must引导的问句时，若是否定答复，不可以用mustn't
而需要用needn't 或是don't have to，因为mustn't意思是"绝不能、一定不要"，而没有"不必"的意思。例如：
--Must we hand in our exercises today ? 我们今天必须交作业吗？
--Yes , you must . 是的，必须交。
--No , you needn't (or , you don't have to ). 不，不必今天交。
2）表示比较肯定的推测。
You must be tired after working so long .你工作这么久以后，肯定累了吧。
You must be a teacher.
3) “must +完成式”表示对过去事情的推测。
It must have rained last night for it is so wet outside . 外面这么湿，昨晚肯定下雨了。
He must have known the answer before.
四）Ought（后接带to的不定式构成谓语动词）应该
1）表示出于职责、义务该做某事
You ought not to be so careless in your work .你不应该在工作上如此粗心大意。
We ought to study hard for the sake of our motherland. 我们应该为了我们的祖国而努力学习。
2) 表示极有可能发生某事
If we set off right now , we ought to be able to get there in time .
如果我们马上出发，我们应当能够按时到达那里。
Tomorrow ought to be a nice day for we have such a fine sunset today . 今天有这么好的晚霞，明天准是个晴天。
五）need用作情态动词时，表示“需要”或“必须”。(need 也可用实义动词。)
1）通常用于否定句和疑问句中，疑问句的肯定回答用must.
I don’t think you need worry.
I hardly need say how much we miss you.
You never need live just like them.
Need I go over all the lessons ?
Yes , you must. / No , you needn’t .
六）dare , dared用作情态动词，表示“敢于”，主要用于否定句、疑问句中。
She dare not stay in the house.
How dared you say that to her ? 你怎么敢对她说那件事？
dare用作实义动词，它既可带的to不定式，也可跟不带to的不定式。
We must dare (to) tell the truth.
She does n’t dare (to) jump from the wall.
Do they dare (to ) swim across the river.
七）shall用作情态动词
1）用于第一人称，表示决心。
We shall not move. 我们决不动摇。
I shall work out the problems.
2）用于第二、第三人称，表示说话者给对方的“命令”、“允诺”、“威胁”等。
If you work well , you shall have a rise. (允诺)
He shall do it by himself. （命令）
She shall not stay in my garden .她不可以呆在我的花园里。
3）用于疑问句中，表示征求对方意见或请示对方。可用于第一、三人称。
Shall we buy a box of chocolates for the children.
When shall we be here tomorrow?
八）should
（用作情态动词时，有时表示具体的意思，有时却没有意义。主要用于下面几个方面。）
1）表示应该

3) 表示过去一个时期习惯性的动作。
When I was young I would sit in the yard and listen to the stories
from my grandmother.
11) had better 和would rather
Had better 为固定词组，不是过去式，而指现在或将来，意思为“最好”，表示劝告或警告，后接动词原形。
You had better play one kind of music if you want to become famous.
Would rather 意思为“宁愿”，“宁可”，表示选择，其后也接动词原形，常与than搭配。I

情态动词must, should, can, may, could, might都可表
推测。
【肯定推测】
1. must用于肯定句，表示较有把握的推测，意为“准是，
一定”。后面接动词原形，表示对现在的推测。如：

5. could, might也可表示推测意义，常用在过去时态中；但在某些场合下，为了使语气更缓和、更委婉，常用could, might代替can, may。如：
They saw something in the sky last night. It could / might be a UFO.
昨天晚上他们看见天空中有个东西。它有可能是不明飞行物。
You may / might / could be very tired.
你可能很累吧！

1. 表示否定的推测时，cant / coul dn’t语气最强，指“不可能”，带有惊异、怀疑的感情色彩。如：
The story sounds reasonable, but it cant be true.
这个故事听起来合情合理，但不可能是真的。
2. 语气不很肯定时，常用may not或might not表否定推测，意为“可能不，也许不”。如：

仁爱版八年级英语情态动词专题 一、教学内容：情态动词 二、重难点内容：情态动词的语法特征及用法 三、具体内容： 1. 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，分词等形式。 2 比较can 和be able to (1)can/could 表示能力；可能（过去时用could）, 只用于现在式和过去式（could）。be able to可以用于各种时态。 例如：They will be able to tell you the news soon. 他们很快就能告诉你消息了。 (2)只用be able to的情况：a. 位于助动词后。 b. 位于情态动词后。 c. 表示过去某时刻动作时。 d. 用于句首表示条件。 e. 表示成功地做了某事时，用was/were able to，不能用could。 例如：He was able to flee（逃走）Europe before the war broke out. = He managed（办理）to flee Europe before the war broke out. 他在战争爆发之前逃离欧洲。 注意：could有时不表示时态 (1)提出委婉的请求，（注意在回答中不可用could）。 例如：Could I have the television on? 我能看电视吗？ Yes, you can. / No, you can’t. 可以/不可以。 (2)在否定句、疑问句中表示推测或怀疑。例如： He couldn’t be a bad man. 他不大可能是坏人。 3. 比较may和might (1)表示允许或请求；表示没有把握的推测；may 放在句首，表示祝愿。 例如：May God bless（赐惠于，赐福于）you! 愿上帝保佑你！ He might be at home. 他可能在家。 注意：might 表示推测时，不表示时态，只是可能性比may 小。 (2)成语：may/might as well，后面接不带to 的不定式，意为“不妨”。 例如：If that is the case, we may as well try. 如果情况确实如此，我们不妨试一试。 4. 比较have to和must (1)两词都是“必须”的意思，have to 表示客观的需要，must 表示说话人主观上的看法，即主观上的必要。 例如：My brother was very ill, so I had to call the doctor in the middle of the night. 弟弟病得很厉害，我只得半夜里把医生请来。（客观上需要做这件事） He said that they must work hard. 他说他们必须努力工作。（主观上要做这件事）
