(完整版)高考情态动词讲解
语法专题（三）情态动词考点归纳考点一：情态动词表示能力1．表现在的或一般的能力：表示现在的或一般的能力用can或be able to，can 比be able to 使用得更普遍。
can 侧重指有能力做某事；而be able to更强调通过努力、克服困难做成某事。
A computer can't think for itself ；it must be told what to do.He is a native speaker of English，so he can of course speak English quite well.2．表示将来的能力：表示将来能力用will be able to。
If you have a good sleep，you will be able to work out this problem.如果你睡个好觉，你就能做出这道题。
3．表示过去的能力：could 表示过去一般的能力，即不表示做或未做某事；而was （were） able to do则表示过去有能力并且成功地做了某事，相当于managed to do something/succeeded in doing somethin。
g考点二：情态动词表示推测（可能性）可能性可分为客观的（理论的）可能性和具体事情实际发生的可能性。
1．客观的（理论的）可能性指并不涉及具体某事是否会发生，此种用法常常可以说明人或事物的特征。
can 用于肯定句中表示客观的（理论的）可能性，can用于疑问及否定句中则表示实际发生的可能性。
The World Wide Web is sometimes jokingly called the World Wide Wait because it can be very slow.A left- luggage office is a place where bags can be left for a short time，especially in a railway station.2．表示具体事情实际发生的可能性：表示具体事情实际发生的可能性的这些词后接动词原形是对现在事情的推测，后接完成式则表示对过去事情的推测；其中can，may/might，should，ought to，must 有时还可接进行时表示对现在正在进行的事情的推测。

-----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。

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。

3.3表坚定的建议例如：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。

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。
