can和could情态动词

第一篇：can和could情态动词

英语人教版八年级下册情态动词can和could微课教学设计()

初中英语语法教学微课教学设计(情态动词can和could)

教学思路: 本节课我教的是情态动词can和could作“能力”解时的区别。这节课我打算通过复习以前学过的情态动词can的用法，以及通过做游戏，让学生在轻松愉快的氛围中掌握can的用法，以及了解can和could的区别。

一、teaching content: topic: unit 5 can you play the guitar?

grammar：using “can”/ “could” to talk about ability

二、teaching aims: 1.use can talk about the ability at present. 2.use could talk about ability in the past.

三、teaching key and difficult points: how to use “can” and “could” to express ability in the present and past.

四、teaching methods: task-based language teaching method

五、teaching procedures: step 1：warming up

task 1: revision t: what can you do now? s1: I can sing. s2: I can draw s3: I can dance. t: can you ride a bike / swim / fly a kite / play football / play chess? ss: Yes , I can. / no, I can’t.

task 2: playing a game t: now let us play a game. five students come to the front and perform for the class according to my instructions. and gestures. the others answer my questions. t : what can she do? ss : she can ride a bike /swim/ fly a kite/ play football / play chess . t: can she swim/ fly a kite/play football /play chess. ss: yes ,she can? no, she can’t. t: say the whole sentences: eg: a can ride a bike. he can’t / cannot swim. step 2: presentation

t: can you ride a bike now? s1:yes. I can t: could you ride a bike five years ago ? yes, I could./ no, I couldn’t ( help him answer) s1:yes, I could./ no, I couldn’t.

t: we can use “could” t talk about the past

.e.g I can play computer now .but, last year i couldn’t play. t: could you row a boat last year? s1:yes I could . no, I couldn’t.

t: could she he row a boat last year?( ask other students) ss: yes she he could . no she he couldn’t t: yes , a could ride a bike five years ago. he couldn’t swim five years ago.

(teach the students to say the whole sentences): a could ride a bike five years ago. he couldn’t swim five years ago.) (ask other students in the same ways) step 3: practice :work in pairs t: ask your partner more questions eg: could he / she …?

(yes, he / she could. / no, he / she couldn’t.) ... step 4: production task 3: explanation t: let’s work out the rule. ① 肯定句式: can could ② 否定句式: can’t couldn’t ③ 疑问句式: can …?could …?

t: we can use “am (is , are) able to “ instead of “can”, and “was (were) able to “ instead of “could“.

eg.①mike can sing more than 20 English songs. mike is able to …

②she could speak English when she was four. she was able to…

t: please give more examples. to practice them. step 5: summary

t: in this class, we have learnt the use of can and could about talking about abilities .who knows the differences between “can” and “could” step 6: homework

finish off the practice on the workbooks ,fill in the blank with can/could

第二篇：情态动词can的教学设计

情态动词can的教学设计 发布者： 付贤彦

教学目标：

1.知识目标：掌握本课的大纲词汇和情态动词can的用法。

2.能力目标：1)能听懂会不会那些体育运动项目话题的有关的简单会话。

2)能用can或can„t表述会不会那些体育运动项目。 3.文化意识：了解国内外常见的体育运动项目，以及运动项目的种类。 4.学习策略：培养学生在大信息量(许许多多的运动项目中)的语言活动中搜索处理语言信息，发现，归纳学习重点，从而掌握本单元重点学习内

容。

教学内容： 1.大纲词汇sport, throw, race, field, 新课标词汇high jump, long jump, event, track

2.句型 he can / can‟t …

教学重点： 用情态动词can表示会不会那些体育运动项目的句子

教学手段： 多媒体。

教学步骤

教学第一个环节： 创设情景，导入新课

1. 将有关表示体育运动项目的图片由运动员进行曲连接起来，向

学生们展播，从而引出sports meeting和sports event词汇。 2. 要求学生以brainstorm的方式说出what sport they know 3.把学生已知和未知的有关体育运动项目的 图片和单词卡片给学生(4人一组)把词

与图联系起来。 (这是学生们做练习的情景) (以下是课堂练习内容)

baseball skate swim basketball badminton ski football 100-meter hurdles high jump tennis surf table tennis long jump 100-meter race shot put long jump

4. 学习新单词

throw the shot put do the high jump do the long jump do the 200 – meter run run the 110-meter hurdles

5. 检查单词

1)个人或集体朗读单词。

2)做游戏(根据老师所给的图片一人比划另一人猜出这个单词或一人用英语说出图片的意思另一人 猜出这个单词。(3组练习)

设计意图：教材1.1中教学内容生词量较大，平时又很少遇到，学习起来比较枯燥，难以记住。但用音乐将图片连接起来，充满激情的音乐营造了欢快的学习气氛，使学生情绪高涨，同时又陶冶了学生的情操。说出已知的单词和图与词连接的练习，可以展示学生自主学习的成果。让学生听着音乐，看着图片，在不知不觉中学习了单词，并自然而然地让学生融于英语学习的情境中，大大激发了他们的学习兴趣，又以游戏的形式检查单词，有趣的画面，难忘的表演，吸引了学生的注意力加深了他们对单词的印象。为后面的学习内容打下了基础

在这个教学环境中，学生是活动的主体，教师只充当了“节目主持人”的角

色。

第二个环节：师生互动，学习探究

1. 看海报，回答问题 t: what‟s the poster about?

ss: sports events

t: how many events for boys?

ss: ten

t: how many events for girls?

ss: seven 2.听录音完成1.1练习(巩固所学单词)

3听录音完成1.2练习。

gary can run the 110-meter hurdles. true false he can do the high jump. true false he‟s fast. true false he can‟t throw the shot put. true false he can do the long jump. true false 4.让学生朗读1.2和1.3的句子 。学生通过观察，讨论，总结，归纳can

的用法。 设计意图：

听的环节是“输入”的过程，带着问题听，让学生在听的过程中有的放矢，有效捕捉信息，同时又提醒学生注意观察并发现需要注意的表达方式，为后面的语言实践准备实用句型。这种让学生在具体的语境中发现新句型的教学方法，能有效地提高学生分析问题和解决问题的能力，避免了传统的教师为主体的抽象的语法说教，调动了学生思维积极性，给学生提供了提高观察能力，分析能力和归纳总结能力的发展平台。学生们以小组讨论的方式进行观察，探讨，分析，归纳，得出正确结论。让所有的学生都参与讨论探究，这既体现了以学生发展为本的教育思想，又调动了学生的积极性与创造性。学生们自己发现的规律要比老师讲解所学到的规律在脑海中

的印象深刻得多，理解的透彻。 第三个环节：合作交流，巩固提高

1.看图说话 (i can / can‟t… he can / can‟t… they… we…

设计意图：

在这个环节中，我向学生提供了 具有直观性的图画，让学生觉得有内 容说，新学的句型在这一活动中得到

充分运用和巩固。

(学生练习时的情景) 2.做链接游戏 4人一组。 第一个同学说 i can swim. 第二个同学说 i can‟t swim, but i can skate 第三个同学说：i can‟t skate, but i can do

the high jump. 第四个同学说：i can‟t do the high jump, but i can do the long jump.

设计意图：

变换语境操练是机械模仿进一步的发展，对语言运用的能力的要求又有所提高，有利于开发学生的创新能力和求异思维能力，这样的活动增加了

趣味性，使紧张的气氛得到缓解。 3. 采访同学看谁能做：要求用句型 can you do…提问，用 i can…

根据我课前调查我写了以下词组

play basketball，

sing well run fast, dance well, play the piano, run the 100-meter race. 学生们可以下位子采访，谁先找到这六位同学，谁得第一，并给与奖励。我又让能唱能跳的学生在班上即兴表演，又一次掀起了高潮。

设计意图：

新课程标准倡导主动参与，乐于探索，勤于思考，培养学生收集和处理语言信息的能力。通过这一环节的练习，不但学生的语言技能得到了提高，而且他们的情感态度和学习策略都得到了培养，同时他们的语言知识还得到了复习和巩固。这样的练习可以充分调动学生的参与热情，激发学生的

学习兴趣。

4. 让学生用what can you do? 及本节课所学的句型编一个对话，内容是学生会体育部和文艺部招聘人员。(两人一组)

a: what club do you want to join? b: we want to join the music club./ the sports club.

a: ___________________? b: i can sing / play basketball. a: ___________________?

b: yes, i can.

a: ____________________?

b: no, ________________. a: ok. welcome to join us.

设计意图：

让学生体验不同的角色，参与实践，合作交流，从而提高语言的运用能力。让所有学生全面参与，使学生的思维一直处于积极的状态，提高课堂教学

质量 教学反思：

新课标注重学生的情感因素，着力培养学生的学习兴趣，激发学生的学习动机和培养他们热爱生活的品质。在英语教学中适当运用游戏教学可使学生在玩中学，变无意注意为有意注意，使学生在游戏之中实实在在地进行语言信息交流，避免了枯燥的死记硬背，激发了学生的学习兴趣，曾强了学生学好英语的信心和决心，使良好的英语学习心理素质在游戏之中逐渐培养起来。新课程标准从某种意义上说对老师提出了更高的要求，作为英语老师，我们要及时转换自己的角色和观念，做一名出色的节目主持人，组织好每一项课堂活动，把表演的机会给学生，让学生成为真正的“主角”，让学生时刻处在体验，实践，参与，合作与交流的活动中，使他们的语言技能，语言知识，情感态度，学习策略和文化意识等素养得到整体发展.

第三篇：情态动词教案

情态动词

1. 概念: 情态动词: 表示说话者的某些观点或态度的词语.如 “能” , “或许” , “必须” , “需要” , “应该” 等. 2. 情态动词主要有: can, may, must, need, should, … 这些情态动词后面 + 动词原形. 3. 用法

eg: I can play basketball. 我会打篮球.

---Can you play basketball ? 你会打篮球吗? --- Yes, I can. / No, I can’t. 是的, 我会. / 不, 我不会.

⑵ 表示怀疑、猜测，常用 be 连用, 放在否定句和疑问句中。如：

eg: He can’t be in the room. 他一定不在房间里.

⑶ 表示请求或允许, 多用于口语中, 意为”可以”, 相当于 may. 如:

eg: You can go now. 你现在可以走了.

② could ⑴ 是can 的过去式, 表示过去的能力. 如:

eg: I could swim when I was a child. 当我还是一个小孩子的时候我就会游泳了.

⑵ couldn’t: “不能” 用could 提问肯定和否定回答分别用 could, 和 couldn’t.

第四篇：情态动词小结

情态动词有：can(could)， may(might)， must，have to, shall(should)，will(would)，need, dare, ought to等。 一. 情态动词can, may, must用法 ㈠基本用法 1. can ⑴ 会，能够 --Can you swim? --Yes, I can. --No, I can‟t. ⑵ 口语中代替may. You can (may) park here. 你可以把车停在这里。(许可) 2. may允许，许可 --May I come in? --Yes, you may./Sure, come on in. --No, you mustn‟t./No, you can‟t.

No, you‟d better not. 3. must必须 --Must we finish the exercise today? --Yes, you must. --No, you needn‟t./No, you don‟t have to. 4. need 需要，必需--Need you go now?= -- Must you go now? --Yes, I must. --Yes, I must. --No, I needn‟t. --No, I needn‟t. (need作为情态动词，通常用在否定句和疑问句中。)

1 注意一：can 与be able to 都可以表示“能力”，区别是： ⑴ can只有现在和过去两种形式

I can play the piano. She couldn‟t play the piano when she was a little girl. ⑵ be able to ① 有更多的形式和时态

We shall/will be able to finish the work next week. I haven‟t been able to find the book. ② 指具体一次活动

I can swim but I am not able to cross the rough sea. 有时两者可以互换: I‟m not able to (can‟t) answer your question. Are you able to (Can you) type(打字)?

注意二：could的用法

⑴ 作为can的过去式，表示过去的能力。

When I was young I could climb any tree in the forest. 这时也可用was(were)able to ⑵ 用来代替can，婉转地提出请求，想法，建议等。回答这种情况下could引导的一般疑问句时，不用could，而要用can。 A: Could you tell me how to get to the hospital? B: Of cause, I can. 注意三：must的否定形式表示“不得”，“一定不要”，“禁止”

2 ① You mustn‟t take photos in here. It‟s forbidden(禁止). ② You mustn‟t drive without a license(驾照). ③ We mustn‟t be late, must we?

(与第4页对比，此must不表猜测,两回事。) 注意四：must的过去式是must，常用 had to 代替。 I had to see the dentist. 注意五：must 和 have to 都可以表示必须，但must表示说话人的主观看法，have to表示客观需要。 You must say sorry to me for that. You have to drive quickly, we have little time. 注意六：May+动词原形表“祝愿”。

May you succeed. May you be happy every day. ㈡ 可能性用法

1. can表示“可能性”① 疑问句：只能用can

Who can it be ?

② 否定句：cannot(can‟t)“不可能 It cannot be Jenny. 2. may表示“可能性”① 否定句：may not“可能不”

It may not be Jenny.

② 肯定句：“大概”，“也许”，“可能” It may be Jenny.

3 3. must表示“可能性”，只能用于肯定句，表推测：“一定是”，“准是”，“必是”，“必定”。

It must be Jenny. 小结表示“可能性”：

疑问句：只能用can 否定句：cannot(can‟t)“不可能”(反义词是must“准是”) may not“可能不”

肯定句：may “大概”

must“准是”(反义词是can‟t) 注意一: 在表示“可能性”时，凡是对过去事物的猜测，不管是疑问..句，否定句还是肯定句，都要用完成时。 ...① It must have rained last night. You see, the ground is still wet. ② He can‟t have been to your home. He doesn‟t know your address注意二：may+原型 表示 现在或将来的可能性。若表示对过去事物 .... 的猜测，则用完成时。 ③ He may come today.(tomorrow) He might come today.(tomorrow) (might语气更不肯定，不是may的过去时) ④ She might have called for help.她可能大声喊“救命”了。 请翻译下里句子：

1. Where can Wei Fang be?

4 2.That can‟t be Mary. She is in hospital. 3. Surely you can‟t be hungry. You‟ve only just had lunch. 4. The key can‟t be in the room. I have just searched it carefully. 5. You may/ can go and ask him. But he may not answer you. 6.A：Look! Someone is coming. Who can it be? B: It may be our headmaster. A: It can‟t be him. He has gone to Shanghai. B: It must be Mr. Zhang. He looks like our headmaster. 7. Anna may know Tom‟s address. 8. They may be waiting at the station. 9. I may be going to Europe next year. 10.He may have gone abroad. 11. I‟m afraid I must be going now. 12. You must be hungry. Have something to eat. 13. They must be twins. 14. There‟s a lot noise from next door. They must be having party a party. 15. I can‟t find him anywhere. He must have left. 16. I can‟t find my book. I must have left it at home. 17. You must have been thinking of something. 18. A: We went to Hainan for the winter vacation.

5 B: That must have been nice. 注意三：must表示猜测时的反义疑问句

⑴ “must be +表语”的结构，must表示肯定猜测时，含有“准是”，“势必”，“一定”等意义时，反义疑问句用“isn‟t/aren‟t+主语” They must be hungry after the long walk, aren‟t they? ⑵ “must have done” 表示猜测时，反义疑问句用“haven‟t/hasn‟t +主语”或“didn‟t+主语”

① They must have studied English before, haven‟t they? ② She must have met a fairy(仙女), hasn‟t she? ③ You must have seen the film last week, didn‟t you? ........解题秘笈：① 把must去掉 ② 找时间状语 ③ 重新组成一新句子 ④ 按新句子的时态造反义疑问句

① You must have been to Beijing, ___ __?

去掉must;无时状;重组成You have been to Beijing; 故答案为：haven‟t you ② You must have finished your homework yesterday, .........___ __?去掉must;时状为yesterday; 重组成 You finished your homework yesterday; 故答案为：didn‟t you 二.情态动词need的用法

⑴ need 表示“需要”，“必需”。作为情态动词，通常用在否定句和疑问句中。

① He needn‟t pay for it.( 情态动词)

6 =He doesn‟t need to pay for it.(行为动词) ② --Need you go now?= -- Must you go now? --Yes, I must. --Yes, I must. --No, I needn‟t. --No, I needn‟t. ⑵ need也可用作行为动词，其变化与一般动词相同。 ① We need to think it over.(肯定句) ② Does he need to know it?=Need he know it? ③ She didn‟t need to go.=She needn‟t go. ⑶ 按句型背：

need doing=need to be done ① The door needs painting. =The door needs to be painted. ② The old man needed looking after. = The old man needed to be looked after. 三.情态动词dare的用法

⑴ dare 表示“敢” 作为情态动词，通常用于否定句，疑问句或条件句中。dare 作为情态动词只有两种形式:dare, dared(当主语是第三人称单数时，dare 不加s) ① She dare not do so.(否定句) ② Dare he do it? (一般疑问句) ③ How dare you say I‟m unfair. (特殊疑问句) ④ Jump if you dare.有胆量你就跳。(条件句)

7 ⑵ 除了在“I dare say…” 这种习惯用语中，dare 在肯定句中作 情态动词的情况是很少的。(特殊用法，口语中常用，按句型背) ① I dare say you are wrong. ② A: If you die, who will get your money?

B: I dare say my uncle will. I have no other relatives. (亲戚) ⑶ dare 也可用作行为动词，其变化与一般动词相同。 ① Who dare to go? ② I don‟t dare (to) ask her. 问：此句中的to 为什么可以省略?
