文档大全专题七情态动词和虚拟语气常考点
近两年考查情态动词和虚拟语气的频率呈上升趋势。从整体上把握情态动词的语法特征和语义特征，能够准确理解不同情态动词的细微差异，认真区别具有相同功能、意思相近的情态动词的用法，在真实的交际情景中印证和领悟情态动词的用法和特征。
1 情态动词所表示的多种含义
1. can和could的用法
①表示能力。如：
I can run fast.
②表示客观可能性。如：
An experienced driver can have an accident at times. ③表示请求和允许。用could 语气更委婉。如：
—Can/Could I go now? —Yes，you can.
④表示猜测、惊异、怀疑、不相信的态度(主要用于否定句、疑问句或惊叹句中)。如：Can this be true?
How can you be so careless! This cannot be done by him. 2. may和might的用法
①表示许可。如：
You may drive the car.
—May/Might I use your pen? —No，you mustn't.
②用于祈使句中表示祝愿。如：
May you succeed!
③表示推测、可能(疑问句不能用于此意)。表推测的might并不是指过去时间，而表示比may把握性略小些。如：
He may be very busy now.
④用于表示目的或让步状语从句中。如：
No matter what difficulties you may come across，you shouldn't give up. 3. will 和would的用法
①用于各种人称，表示“意志”“意愿”“决心”等。如：
I told her to stop crying，but she just would not listen.
②用于第二人称的疑问句，表示说话人向对方提出请求。用would比用will语气更客气。如：
Will/Would you please keep the door open? ③表示真理或习惯，意为“惯于，总是”。如：
She will listen to music alone in her room for hours. He would get up early when
he lived in the country. 4. should的用法
实用标准文案
文档大全①表示现在或将来的责任或义务，意为“应该，应当”，这时它可以和 ought to，be supposed to 互换使用。如：
You should(＝are supposed to ) complete your test in time.
②表示有较大可能实现的猜测、推论，通常意为“可能；总该……吧”，相当于 be expected to。如：
They should be home by now，I think.
③用于第一人称时可以表示说话人的一种谦逊、客气、委婉的语气。如：
I should think it would be better to try it again.
④用在条件状语从句中，表示语气较强的假设，意为“万一”，这时也可将should置于从句之首，即将should放在主语前面，而省略从属连词if，主句谓语却不一定用虚拟语气。如：
Should I (＝If I should) be free tomorrow I will come.
⑤用来表示意外、惊喜或者在说话人看来是不可思议的。尤其在以 why，who，how 等开头的修辞疑问句或某些感叹句中常常意为“竟会，居然”。如：
A gentleman like him should be rude to a lady! ⑥用于虚拟语气句中(略)。
5. ought to的用法
表示应该、推测，相当于should。如：
You ought to take care of him. 6. shall的用法
①用于第二、三人称，表示说话人的意愿，有“命令”“警告，威胁，强制”“法令条文规则”和“允诺”等意思。如：
You shall have the book when I finish reading.(表允诺)
②在疑问句中，shall用于征求对方的意见或请求指示，常用于第一、第三人称。如：Shall we go out for a walk? Where shall he wait for us? 7. must的用法
①表示义务、意图或建议，意为“必须，应该，禁止(用于否定句中)”。如：
You must go and see that film—you'd really enjoy it. ②表示推测，意为“必定，一定”。
[注]must表示推测时的否定式是can't或couldn't(不可能)。
③表示主张，意为“硬要，一定要”。如：
If you must go，at least wait till the rain stops. ④表示与说话人愿望相反，意为“偏要”。如：
The machine must break down at this busy hour. 8. need和dare的用法
①need 作“必要”讲时，既可作情态动词，也可作实义动词。作实义动词时后面的动词不定式要带to，其变化与一般动词相同。作情态动词时，仅用于否定句或疑问句中。
②dare作为情态动词时，仅用在疑问句、否定句和条件从句中。dare若作实义动词，后面可接带to的不定式，此时to也可以省略。dare与need的用法相似。如：
He dares to go there alone. He needs to go there alone.
She doesn't dare (to) ask her father. She doesn't need to ask her father.
