高中英语情态动词详解及练习

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CanI ... 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。

高中英语语法专攻-《情态动词》【考点1-can&could】·can和could 表推测对现在或将来的推测，两者均可用，但can 通常只用于否定句或疑问句中，一般不用于肯定句，而could则可用于肯定句、否定句和疑问句；对过去的推测，应在can,could 之后接动词的完成式，且此时can仍只用于否定句或疑问句，不用于肯定句；而could 则可用于各种句型。

如：Can [Could] this be true? 这能是真的吗Where can [could] he have gone? 他能到哪里去了呢She can’t [couldn’t] have left so soon. 她不可能走得这么早。

He could have gone home. 他可能已回家了。

【注：could后接动词的完成式，除表示对过去的推测外，还可表示过去没有实现的可能性（即某事本来可以发生，却没发生），或委婉地责备某人过去应该做某事而没有去做（此时不用can）。

】如：You could have started a little earlier. 你本可早点动身的。

You needn’t have co oked it. We could have eaten it raw.你其实可以不煮熟（它），我们（本来）可以生吃。

·can和could表允许表示现在的允许时，若是请求别人允许自己做某事，两者均可用，但用could 语气更委婉；若是自己允许别人做某事，一般只用can，而不用could。

如：Can [Could] I come in? 我可以进来吗“Could [Can] I use your pen? ” “Yes,of course you can.”“我可以借用你的钢笔吗?”“当然可以。

”（不能说Yes,you could.)表示过去的允许时，若表示过去一般性允许（即表示某人随时都可以做某事），用could；若表示在过去某一特定情况下允许进行某一特定的活动，则不用could。

【英语】高中英语情态动词解题技巧及练习题及解析一、单项选择情态动词1．—________ the woman with the baby come over? We have a seat here.—Thank you, sir. Actually I do have my seat here. But my baby likes to look out of the window. A．Would B．ShallC．Must D．May【答案】A【解析】【详解】考查情态动词。

句意：——那位抱小孩的女士，要不来这边吧?这儿有个座位。

——谢谢，实际上我有座位的，只是我的孩子喜欢看窗外。

would表示婉转的请求，征求对方的意见，Shall提问一般只用于第一人称，我们常说Shall I.或者 Shall we；may表示请求对方允许。

故选A。

【点睛】would的用法1.would 最常见的用法是：相对于一个过去时间点的后来“将要”做什么，比如：He said he would meet me at the station. 他说他会在车站接我的。

这句中的 would meet 是相对于 said （过去说）之后要做的事情。

又如：She thought she would have to ask someone for help. 她当时想，她得找个人帮忙。

2．—You rang me up at about 10:00 last night, didn't you?—No, I didn't phone you. It someone else.A．must have been B．could be C．must be D．could have been 【答案】A【解析】【详解】考查情态动词+have done。

句意：“昨晚10点左右你给我打了电话，是吗？”“不，我没给你打电话。

一定是别人干的。
