may 可以

will ，would （表意愿） need 需要 dare 敢 must 必须 have to 不得不

shall ，should 应该（表义务） ought to 应该

1.can ，could 的用法

1.1表能力，有“能”、“会”、“能够”的意思例如：Can you drive a car? 你会开车吗？ -----Yes, I can. 我会。 -----No, I can't. 我不会。

1.2表允许，在口语中代替 may ，有“可以”的意思

例如：Can I use your bike? 我可以用你的自行车吗？ 1.3表示可能性，常用于否定句和疑问句例如：Can it be true? 那会是真的吗？

Today is Sunday. He can't be at school. 今天是星期天。他不可能在学校里。

1.4过去式could 表示的语气更加委婉、客气

例如：Could I come to see you tomorrow? 明天我可以来见你吗？

1.5 can 和 be able to 的比较

1) can 只有一般现在时和一般过去时两种时态(could)，其他时态要用be able to 的形式

例如：I haven't been able to get in touch with her. 我一直没能和她联系上。

2) 通常can 和 be able to 可以互换

例如：He will come if he can.如果可能的话，他一定会来。 2.may ，might 的用法

2.1表示许可或征求对方的许可，有“可以”的意思。例如：You may go now. 你可以走了。

May I use your computer? 我用一下你的电脑可以吗？ 2.2回答以may 开头的疑问句有如下表达法：例如：May I smoke here? 我可以在这儿抽烟吗？ -----Yes, you may. -----Yes, please. ------No, you can't. ------No, you mustn't. ------No, you'd better not.

2.3表示猜测，通常只用于陈述句

例如：You may be right. 你可能是对的。 2.4过去式might 表示的语气更加委婉、客气

例如：Might I use your pen for a while? 我能用用你的钢笔吗？

2.5在口语中can 可以代替may 表示许可，但can 较随便，may 更正式

例如：Can I use your bike, John? 约翰，我可以用一下你的自行车吗？

May I have a look at your license please, sir? 先生，我可以看一下你的执照吗 3.must 的用法 3.1表义务，“必须” 例如：You must talk to them about their study. 你必须同他们谈谈关于他们学习的事。

例如：You must come and see us as soon as you get to Shanghai. 一到上海你就得马上来见我们。 3.4表推测，暗含有很大的可能性

例如：He must be ill. He looks so pale. 他肯定是病了。他的脸色那么苍白。［注意］

may 暗含的可能性较小，must 暗含的可能性较大。 3.5关于must 的简短回答：

例如：Must I clean the dining room at once? 我必须马上打扫餐厅吗？

------Yes, you must. ------No, you needn't. ------No, you don't have to. 4.have to 的用法

have to 虽属于情态动词，但它有人称、数的变化，它的疑问句否定句的构成也和其他情态动词有所不同。 4.1 have to 表客观的需要和义务，must 表主观认识

例如：I missed the train, so I had to take a taxi. 我没搭上火车，所以我只得打的。

4.2在疑问句和否定句中，have to 多用助动词do 构成，must 则直接提前或加not 。

例如：Did he have to do it? 他得做那件事吗？

―――He didn't have to do it. 他不需要做那件事。 4.3在否定句中，have to 表示不需要，must 表不允许。例如：You don't have to go there. 你不需要去那儿。 You mustn't go there? 你不可去那儿。

4.4虽然must 可以用在过去时态中，但是have to 更能直接了当的表达过去时间概念。

例如：She must see Hubert that very night. 她必须在那个晚上见到休伯特。

I had to leave at six yesterday. 我得在昨天6点离开。 5.need 的用法

need 既可用作情态动词，又可用作实义动词。作情态动词时，没有数和人称的变化，后接动词原形；作实义动词时，有数的变化和人称的变化，后接带to 的不定式。 5.1用于否定句，表“不必”

例如：You needn't worry. 你不必担心。

I don't think you need worry. 我想你不必担心。 5.2用于疑问句，表“需要吗” 例如：Need you go? 你得去吗？ -----No, I needn't. 不必。

-----Yes, I must. 是的，我必须去。

5.3 need 用作实义动词时，要注意始终以实义动词的标准贯彻到底例如：（正确）Do you need to go there? （错误）Do you need go there?

6.will 和would 的用法

6.1 will ，用于构成将来时是助动词。用于表示“意志”“决心”“请求”是情态动词。would 亦同理。

例如：He'll be here this afternoon. 今天下午他会来这儿。（助动词）

Will you tell her that I'm here? 请您告诉她说我在这儿，好吗？（情态动词）

6.2用于各种人称，表示“意志”“决心”“允诺” 例如：I will try. 我愿一试。

Will you type this, please? 请打印这个，好吗？ Won't you sit down? 请坐下，好吗？ 6.4 would 比will 客气委婉

例如：Would you help us, please? 请您帮助我们，好吗？（表请求）

I'd go there with you. 我要和你一块到那儿去。（表意愿） Dad wouldn't allow it. 爸爸不会允许这件事。（表许可） 7.shall 和should 的用法

7.1 shall 用于构成将来时是助动词，shall 用于征求对方的意见，表示“决心”是情态动词

例如：Perhaps I shall pay a visit to England this winter. 可能今年冬天我会去英国观光。（构成一般将来时，助动词） Shall I turn on the light, Mom? 妈妈，我把灯打开好吗？（用于征求对方的意见，情态动词） I shall be there. 我会到那儿去的。（表“决心”，情态动词） 7.2 should 用于构成将来时是助动词。should 用于表示“应当”“猜测”是情态动词

例如：We thought we should never see you again. 我们以为再也见不到你了。（构成一般过去将来时，助动词） I should write some letters tonight.今晚我得写几封信。（表“应当”，情态动词）

They should be there by now.他们现在可能到了。（表“猜测”，情态动词） 8.ought to 的用法

ought to 表示应该、理应做什么

例如：You ought to clean the classroom , for it is your turn today.你应该把教室打扫了，因为今天是你值日。 9.情态动词表示“推测”的用法

情态动词表示“推测”时，要记住以下两种推测和形式推测： ①对过去发生动作或状态的推测； ②对现在状态的推测。两种形式：

①用情态动词加完成时态表示对过去发生动作或状态的推测；

②用情态动词加动词原型表示对现在发生动作或状态的推测。

具体用法如下：

9.1 must have done 表示过去一定做了什么，语气十分肯定例如：You must have finished your work.你一定完成了你的工作。

9.2 can’t have done 表示过去不可能做了什么，语气也比较肯定(是上面的否定形式)

例如：He can’t have gone to Beijing, for I had a talk with him just now.他不可能去过北京，因为我刚和他交谈过。 9.3 needn’t have done 表示过去没有必要做什么但已经做了。

例如：You needn’t have come earlier. 你不需要来这么早的。

9.4 should have done 过去该做什么但没有做。(含有责备的意思)。例如：You should have started earlier.你本应该早点开始的。 9.5 shouldn’t have done 表示过去不该做什么但做了。(含有责备的意思)

责和义务) 例如：You ought to have helped him. (but you didn’t.)你应该帮助他的。

9.7 can/could do sth.表示对现在情况的猜测，常用于否定句、疑问句或感叹句中。

例如：This news can’t be true. 这消息不可能是真的。 9.8 may/might do sth. 表示对现在情况的猜测，常用于肯定句中。

链接中考语法：情态动词一、情态动词的特点：情态动词，又叫情态助动词。它们具有以下特点： ⑴它们必须与其他动词连用，即：情态动词＋动词原形，表示说话人对所述动作的看法，如需要、可能、意愿或怀疑等。 ⑵绝大多数情态动词没有人称和数的变化，即第三人称单数不加-s（以be和have开头的情态动词短语除外）。 ⑶在意义上，情态动词具有“多义性”。例如：can既可表示能力，又可表示可能、允许等意义。二、部分情态动词的基本用法： 1.can的基本用法： ⑴表示体力或智力上的能力，即“能够，会”，可与beableto转换。例如：HecanspeakEnglish./HeisabletospeakEnglish. 他会讲英语。Canyouplaybasketball— No,I can’t.你会打篮球吗——我不会。如果表示将来具备的能力，要用willbeableto。例如：IfIhaveagoodsleep,Iwillbeabletodotheproblem. 假如我睡个好觉，我就能做那道题目了。

⑵表示许可，主要用于口语，书面语一般用may。例如：Canwegohomenow,please— No,you can’t.我们可以现在就回家吗——不可以。Youcanonlysmokeinthisroom. 你只能在这间房间里抽烟。 You can’t keepthelibrarybooksformorethanamonth.图书馆的书借期不可超过一个月。 ⑶表示“可能”，与may同义，但一般用在疑问句中。例如：Whatcanhepossiblywant他可能会想要什么呢另外，在否定句中，否定形式can’t表示推测“不大可能”。例如：Anybodycanmakemistakes. 任何人都可能会犯错误。Thenews can’t betrue.那消息不大可能是真的。与第一、二人称连用时，还可以就可能的解决问题的方式或可能的行为提出建议。在这里，也可用could使语气婉转。例如： Can/Couldwemeetagainnextweek下周我们可以再见面吗Whatshallwedo—Wecan/couldtryaskingLucyforhelp.我们怎么办呢—— 我们可以请露茜帮忙试试看。Youcan/couldhelpmewiththecooking.你可以帮我做饭。 2.may的基本用法: ⑴表示“许可”，用can比较口语化。例如：Youmay/cancomeifyouwish. 如果你想来，你就来。Youmaynotpickflowersinthispark.
