情态动词用法及练习题一、情态动词的概念：情态动词主要用以表明说话者对某一行为的态度和观点，主要包括揣测、判断、需要及各种意愿。
常见的情态动词有can、may、could、must、have to、should、would等。
二、情态动词的特征(1)情态动词本身有词义，但词义不完整，因此不能独立作谓语，只能和主要动词一起构成谓语。
例如：I can play the piano.（ can play整体为谓语）(2)其后动词使用原形。
例如：You should lie down.(3)情态动词一般没有人称和数的变化(即不管是何人称，后面接的情态动词都不变)。
例如：I/She can sing.(4)它的否定式一般是在其后加 not构成，在一般疑问句中通常将其提到句首。
结构如下：①肯定句：主语+情态动词+动词原形+其他。
例如：He can swim.②否定句：主语+情态动词+not+动词原形+其他。
例如：He can't swim.③一般疑问句：情态动词+主语+动词原形+其他？Yes，主语+情态动词. No,主语+情态动词+not.例如：-Can he swim?-Yes, he can. No,he can’t.④特殊疑问句：特殊疑问词+情态动词+主语+动词原形+其他? 例如： -What can he do ?-He can swim.三.情态动词的用法(1)can的用法①表示“能力”Can you sing?你会唱歌吗?②表示客观条件允许You can listen to music here.你可以在这里听音乐。
You can’t park your car here. 你不能在此停车③can用在否定句和疑问句中时，有时表示说话人的怀疑、惊异、或猜测：It can’t be true.这不可能是事实Can it be true?这可能是真的吗？④.can的搭配用法：A.as +adj./adv.+as one can/could “尽可能，尽量……”，如：The man took his child to the hospital as quickly as he could.这个男人尽可能快地将孩子送去医院。

情态动词一、知识梳理/提炼1. can和could的用法表示能力或客观可能性，还可以表示请求和允许。
如：Can you finish this work tonight?Man cannot live without air.— Can I go now? — Yes, you can.注意：①could也可表示请求，语气委婉，主要用于疑问句，不可用于肯定句，答语应用can （即could不能用于现在时态的简略答语中）。
如：Could I come to see you tomorrow?Yes, you can. （否定答语可用No, I'm afraid not.）②can表示能力时，还可用be able to代替。
如：I'll not be able to come this afternoon.2. may和might的用法1)表示许可。
表示请求、允许时，might比may的语气更委婉一些，否定回答时要用mustn't表示“不可以”、“禁止”、“阻止”之意。
如：You may drive the car.— Might I use your pen? — No, you can’t/ mustn't.Yes, you can/may.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。
在日常口语中，用Can I ... 征询对方意见在现代口语中更为常见。
2) 用于祈使句中表示祝愿。
如：祝你成功！May you succeed!3)表示推测、可能（疑问句不能用于此意）。
他现在可能很忙。
He may be very busy now.3. must和have to的用法1) 表示必须、必要。
如：You must come in time.回答must引出的问句时，如果是否定的回答，不能用mustn't，而要用needn't或don't have to。
【情态动词知识梳理】情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。
考点一：can，may，must等情态动词在陈述句中的用法：1.can的用法：（1）.表示能力、许可、可能性。
表示能力时一般译为“能、会”，即有种能力，尤其是生来具备的能力，此时may和must均不可代替它。
如：She can swim fast, but I can’t .她能游得很快，但我不能。
I can see with my eyes.我用眼睛看。
（2）.表示许可，常在口语中。
如：You can use my dictionary. 你可以用我的字典。
（3）.表示推测，意为“可能”，常用于否定句和疑问句中，此时can’ｔ译为“不可能”。
如：Can the news be true?这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can’t be our teacher. He is on a visit to the Great Wall.不可能。
咱们老师正在游览长城呢。
【例题】—I think Miss Gao must be in the library. Shesaid she would go there.—No. She __________be there, I have just been there.A.can’tB. mustn’tC. needn’tD. wouldn’ｔ2. could的用法：（1）.can的过去式，意为“能、会”，表示过去的能力。
如：He could write poems when he was 10. 他十岁时就会写诗。
（2）. could在疑问句中，表示委婉的语气，此时could没有过去式的意思。
如:Could you do me a favour?你能帮我个忙吗？—Could I use your pen?我能用一下你的钢笔吗?—Yes, you can.可以。
对现在或将来的推测用“情态动词+动词原形”。
【考例2】--What about playing football this afternoon, Sam?--I would rather _______ at home than football. It's too hot outside.A. stay; playingB. stay; playC. to stay; to playD. to stay; playing总结：can/ may/ must/ should用法概览情态动词许可猜测其他表能力，“能够，会”can可以/be able tocan’t不可以不可能表示不能做，能力的缺失表祝愿may可以可能May you be happy!表义务，必须must/一定have tomustn’t不可以，禁止/很大的可能性，should表义务、职责，“应该，应当”“按道理说应该”三、课堂练习一模考点整理--情态动词1.
