初中英语情态动词讲解

初中英语情态动词用法详解【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。 1. can的用法：（1）.表示水平、许可、可能性。表示水平时一般译为“能、会”，即有种水平，尤其是生来具备的水平，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. 你能够用我的字典。（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. She said she would go there.—No. She __be there, I have just been there. 【解析】根据下文“我刚去过那儿”可知，应为“不可能”，can’t表示推测[答案] 2. could的用法：（1）.can的过去式，意为“能、会”，表示过去的水平。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 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.能够。（注意回答） 3. may的用法：（1）.表示请求、许可，比can正式，如：May I borrow your bike?我能够借你的自行车吗？You may go home now.现在你能够回家了。【例题】—_______ I borrow your MP3?—Sure . Here you are. A. May B.Should C.Must D. Would

中考常考的十个情态动词详细讲解

情态动词有具体的词义，但也同助动词一样，需要与动词原形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。一. 10个最重要情态动词的用法 1. can ⑴ 表示能力，一般译为“能、会”，尤其指生来具备的能力。 She can swim fast, but I can’t . 她会游泳，但我不会。 ⑵ 表示许可，常在口语中。 You can use my dictionary. 你可以使用我的词典。 ⑶ 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”。 Can the news be true? 这个消息可能是真的吗？ It can’t be our teacher. He is on a visit to the Great Wall. 不可能是我们老师。他正在参观长城呢。 2. could ⑴ can的过去式，意为“能、会”，表示过去的能力。 He could write poems when he was 10. 他十岁的时候就会写诗。 ⑵ could在疑问句中，表示委婉请求的语气，此时could没有过去式的意思。 Could you do me a favour? 你可以帮我一个忙吗？

—Could I use your pen? 我可以使用你的钢笔吗？ —Yes, you can.（注意回答）可以。 3. may ⑴ 表示请求、许可，比can正式， May I borrow your bike? 我可以借用你的自行车吗？ You may go home now. 你现在可以回家了。 ⑵ 表示推测，谈论可能性，意为“可能，或许”，一般用于肯定句中。 It may rain tomorrow . 明天可能会下雨。 ⑶ may的过去式为 might。might 也可以表示可能性低于may（此时might没有过去式的意思）。 He is away from school. He might be sick. 他离开学校了。也许是病了。 ⑷ 表示希望、祈求、祝愿，常可译为“祝愿”。通常是用may +主+V May you have a good time！祝你玩的愉快！ May you be happy! 祝你快乐！ May you succeed！祝你成功！ 4. must
