第三篇: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.
第四篇:情态动词can的教学反思
教学的方式要以教学的任务和内容、学生的年龄特点和心理需求,灵活多变地加以应用。小学生容易注意力不集中,为了引起学生的注意力并激发学生的学习积极性,
在教学情态动词can 的时候,教师画出下列简笔画:
我边画简笔画边说: I can do a lot of things.What can I do? Do you want to know.Let me tell you.I can play table tennis.(画出第一幅图示并鼓励学生说出动词短语:play table tennis).I can play the piano.(画出第二幅图示并鼓励学生说出动词短语play the piano).I can stand on my head.(画出第三幅图示并鼓励学生说出动词短语stand on my head).然后我叫了五位学生,让他们做动作来告诉大家。我又问:What can he /she do? 让他们说出:I can…….引出另外五个短语:play football, swim, roller blade, ski,ride a horse.接着让学生根椐学过的动词短语用句型Ican ….I cannot….个自写出自己会做的事情和不会做的事情.然后让学生利用句型:What can I do? Can you…? Yes, I can.或No I can’t.互猜彼此会做的事情和不会做的事情。这样可以让学生所学语言产生兴趣,从而激发学生的学习欲望调动学生的学习积极性。
这样通过大量的、反复的、多种形式的操练,要求学生在量中求质,在速度中求准确。
我认为,为了有效地利用练习的时间,提高练习的效率,教师在组织练习时,要分秒必争,争取在有限的时间内,加大练习的强度和密度。
第五篇:情态动词教案
情态动词
【考纲解读】
情态动词与虚拟语气有千丝万缕的联系,它们往往放在一起考查。在近年高考题中,对情态动词的考查几乎每年都有纵观近几年的高考题可以看出,高考对情态动词的考查热点依次是:(1)推测和可能性;(2)“情态动词+have done”结构表示猜测或表示虚拟语气;(3)shall, should, can, must表示特定语气。尤其是对“情态动词+have done”结构的考查频率较高。试题的情景设置往往生动、真实,但考查的角度趋于细微化和综合化,有效信息较为隐蔽,这就决定了情态动词题是难题之一。情态动词题每年都考,所以本专题在高考中的重要地位是显而易见的。因而在复习中应引起高度重视,且依笔者之见,来年高考中对情态动词考查的可能性依然非常大。【知识要点】
一、情态动词的语法特征
1.情态动词不能表示正在发生或已经发生的事情,只表示期待或估计某事的发生。2.情态动词 除ought 和have 外,后面只能接不带to 的不定式。3.情态动词没有人称、数的变化,即情态动词第三人称单数不加-s。4.情态动词没有非谓语形式,即没有不定式,分词等形式。
二、情态动词的基本用法 1.比较can 和be able to 1)can could 表示能力;可能(过去时用could),只用于现在时和过去时(could)。be able to可以用于各种时态。
They will be able to tell you the news soon.他很快就能告诉你消息了。2)只用be able to中情况: 位于助动词后; 情态动词后;
表示过去某时刻动作时; 用于句首表示条件;
表示成功地做了某事时,只能用was/were able to,不能用could。He was able to flee Europe before the war broke out.=He managed to flee Europe before the war broke out.战争爆发前,他就逃离欧洲了。
注意:could,在否定,疑问句中表示推测或怀疑。表示提出委婉的请求(注意在回答中不可用could)。
—Could I have the television on? —Yes,you can./No,you can’t.He couldn’t be a bad man.他不大可能是坏人。2.比较may和might
1)表示允许或请求;表示没有把握的推测;may 放在句首,表示祝愿。May God bless you!愿上帝保佑你!He might be at home.他有可能在家。
注意:might 表示推测时,不表示时态。只是可能性比may 小。
2)may/might as well,后面接不带to 的不定式,意为“不妨,还是……好”。You may(might)as well tell me the truth.你还是对我说实话好。3.比较have to和must
1)两词都是“必须”的意思,have to 表示客观的需要,must 表示说话人主观上的看法,即主观上的必要。
My brother was very ill,so I had to call the doctor in the middle of the night.我弟弟病得很厉害,我只得半夜里把医生请来。(客观上需要做这件事)
He said that they must work hard.他说他们必须努力工作。(主观上要做这件事)
2)have to有人称、数、时态的变化,而must只有一种形式。
He had to look after his sister yesterday.昨天他不得不照看他的妹妹。3)在否定结构中:
don’t have to 表示“不必”(可以不可以都行);mustn’t表示“禁止” You don’t have to tell him about it.你不必把此事告诉他。You mustn’t tell him about it.你一定不要把这件事告诉他。4.must表示推测
1)must用在肯定句中表示较有把握的推测,意为“一定”。
2)must表对现在的状态或现在正发生的事情的推测时,must 后面通常接系动词be 的原形或行为动词的进行式。
You have worked hard all day.You must be tired.你辛苦干一整天,一定累了。(对现在情况的推测判断)He must be working in his office.他一定在办公室工作呢。比较:He must be staying there.他现在肯定在那里。He must stay there.他必须待在那里。
3)must 表示对已发生的事情的推测时,must 要接完成式。I didn’t hear the phone.I must have been asleep.我刚才没有听到电话,我想必是睡着了。
4)must表示对过去某时正发生的事情的推测,must 后面要接不定式的完成进行式。—Why didn’t you answer my phone call?
—Well,I must have been sleeping,so I didn’t hear it.5)否定推测用can’t。
If Tom didn’t leave here until five o’clock,he can’t be home yet.如果汤姆五点才离开这儿,他此时一定还未到家。5.表示推测的用法
can,could,may,might,must 皆可表示推测,其用法如下: 1)情态动词+动词原形
表示对现在或将来的情况的推测,此时动词通常为系动词。I don’t know where she is,she may be in Wuhan.我不知道她在哪儿,她可能在武汉。2)情态动词+动词现在进行时
表示对现在或将来正在进行的情况进行推测。
At this moment,our teacher must be correcting our exam papers.这时,我们老师想必在批改试卷。
3)情态动词+动词完成时表示对过去情况的推测。
We would have finished this work by the end of next December.明年12月底前我们很可能已完成这项工作了。The road is wet.It must have rained last night.地是湿的,昨天晚上一定下雨了。
4)情态动词+动词的现在完成进行时表示对过去正在发生事情的推测。Your mother must have been looking for you.你妈妈一定一直在找你。
5)推测的否定形式,疑问形式用can’t,couldn’t表示。
Mike can’t have found his car,for he came to work by bus this morning.迈克一定还没有找回他的车,因为早上他是坐公共汽车来上班的。
注意:could,might表示推测时不表示时态,其推测的程度不如can,may。6.情态动词+have+过去分词
1)may(might)have+done sth.can(could)have+done sth.表示过去,推测过去时间里可能发生的事情。
Philip may(might)have been hurt seriously in the car accident.飞利浦在那场车祸中有可能伤的很严重。
2)must have+done sth.对过去时间里可能发生的事情的推测,语气较强,具有“肯定”“谅必”的意思。
—Linda has gone to work,but her bicycle is still here.—She must have gone by bus.3)ought to have done sth./should have done sth.本应该做某事,而事实上并没有做。否定句表示“不该做某事而做了”。
He ought not to have thrown the old clothes away.(事实上已扔了。)ought to 在语气上比should 要强。4)needn’t have done sth.本没必要做某事 I dressed very warmly for the trip,but I needn’t have done so.The weather was hot.那次旅行,我穿的非常暖和,但我本没有必要那么去做。天太热了。5)would like to have done sth.本打算做某事
I would like to have read the article,but I was very busy then.我本想读那本书,但我那时太忙了。7.should 和ought to
should 和ought to 都为“应该”的意思,可用于各种人称。—Ought he to go?
—Yes.I think he ought to.表示要求,命令时,语气由 should(应该),had better最好),must(必须)渐强。8.had better表示“最好”
had better 相当于一个助动词,它只有一种形式,它后面要跟动词原形。had better do sth.最好干某事
had better not do sth.最好不干某事
had better have done sth.表示与事实相反的结果,意为“本来最好”。9.would rather表示“宁愿” would rather do 宁可干某事
would rather not do 宁可不干某事 would rather...than...宁愿……而不愿
还有would sooner,had rather,had sooner都表示“宁愿”“宁可”的意思。I would rather stay here than go home.=I would stay here rather than go home.我宁可待在这儿也不回家。
10.will和would
1)would like;would like to do=want to 想要,为固定搭配。Would you like to go with me?你想和我一块儿去吗?
2)Will you...? Would you like...?表示肯定含义的请求劝说时,疑问句 中一般用some,而不是any。
Would you like some cake?要蛋糕吗?
3)否定结构中用will,一般不用would,won’t you是一种委婉语气。Won’t you sit down?你不坐吗? 11.情态动词的回答方式
must和need相同:Yes,...must.No,...needn't/don't have to may和can could相同:Yes,...may/can/could.No,...mustn't/...'d better not/can't.shall:Yes,...can/may.No,...can't.should:Yes,...should.No,...shouldn't.will和would差不多:Yes,...do/will.No,...won't/thanks.典型例题
1)---Could I borrow your dictionary?---Yes,of course,you____.A.might B.will C.can D.should 答案C.could表示委婉的语气,并不为时态.答语中of course,表示肯定的语气,允许某人做某事时,用can和 may来表达,不能用could或might.复习:will 与you连用,用来提出要求或下命令.should与you 连用,用来提出劝告.2)---Shall I tell John about it?---No,you ___.I've told him already.A.needn't B.wouldn't C.mustn't D.shouldn't 答案A.needn't 不必,不用.wouldn't 将不,mustn't 禁止、不能.shouldn't 不应该.本题为不需要,不必的意思,应用needn't.3)---Don't forget to come to my birthday party tomorrow.---______.A.I don't B.I won't C.I can't D.I haven't 答案B.will既可当作情态动词,表请求、建议、也可作为实义动词表“意愿、意志、决心”,本题表示决心,选B.12.比较need和dare
一、need表示“需要”或“必须”,作情态动词时,仅用于否定句或疑问句中,在肯定句中一般用must,have to,ought to,或should代替。多用在否定式或疑问句中.1.Need I attend the meeting tomorrow?
我需要明天参加会议吗? 2.You need not hand in the paper this week.这一周你不必交论文。
need 是一个情态动词,他的用法完全和其他情态动词一样,但 need 还可当作实义动词使用,这时 need 就象其他动词一样,有第三人称,单复数,后面加带 to 的动词等特性。1.I need a bike to go to school.我上学需要一辆自行车。2.Do you need a dictionary? 你需要词典吗? 3.She needs a necklace.她需要一条项链。
needn't + have + 过去分词 表示过去做了没必要做的事情。You needn't have taken it seriously.这件事情你不必太认真。
二、Dare表示“敢”,Dare作情态动词时,主要用于疑问句、否定句和条件从句中,一般不用在肯定句中。多用在否定或疑问句中。1.The little girl dare not speak in public.小女孩不敢在公众面前说话。2.Dare you catch the little cat? 你敢抓小猫吗? dare 除用作情态动词外,更多的是当实义动词使用,用法同实义动词一样,要考虑人称,单复数,时态等。
1.Do you dare to walk in the dark? 你敢黑夜走路吗?
2.He doesn't dare to tell the teacher what happened that day.他不敢告诉老师那天发生的事。
三、Dare和need常用作实义动词,有时态、人称和数的变化,所不同的是,作实义动词时,在肯定句中,dare后面通常接带to的不定式,在否定和疑问句中,dare后面可接带to或不带to的不定式。如:
I dare to swim across this river.He does not dare(to)answer.Don't you dare(to)touch it!I wondered he dare(to)say that.He needs to finish it this evening.另外need 的被动含义:need,want,require,worth(形容词)后面接doing,也 可以表示被动:need doing=need to be done Shall用于第一人称,表示征求对方的意愿.如:What shall we do this evening? 2.Shall用于第一、第三人称疑问句中,表示说话人征求对方的意见或向对方请示.如:Shall we begin our lesson? When shall he be able to leave the hospital? 3.Shall用于第二、第三人称,表示说话人给对方命令、警告、允诺或威胁.如:You shall fail if you don't work harder.(警告)He shall have the book when I finish reading.(允诺)He shall be punished.(威胁)
