第一篇：情態(tài)動詞can的教學設計

情態(tài)動詞can的教學設計 發(fā)布者： 付賢彥

教學目標：

1.知識目標：掌握本課的大綱詞匯和情態(tài)動詞can的用法。

2.能力目標：1）能聽懂會不會那些體育運動項目話題的有關的簡單會話。

2）能用can或can?t表述會不會那些體育運動項目。3.文化意識：了解國內外常見的體育運動項目，以及運動項目的種類。4.學習策略：培養(yǎng)學生在大信息量（許許多多的運動項目中）的語言活動中搜索處理語言信息，發(fā)現，歸納學習重點，從而掌握本單元重點學習內

容。

教學內容： 1.大綱詞匯sport, throw, race, field, 新課標詞匯high jump, long jump, event, track

2.句型 he can / can?t …

教學重點： 用情態(tài)動詞can表示會不會那些體育運動項目的句子

教學手段： 多媒體。

教學步驟

教學第一個環(huán)節(jié)： 創(chuàng)設情景，導入新課

1.將有關表示體育運動項目的圖片由運動員進行曲連接起來，向

學生們展播，從而引出sports meeting和sports event詞匯。2.要求學生以brainstorm的方式說出what sport they know 3.把學生已知和未知的有關體育運動項目的 圖片和單詞卡片給學生（4人一組）把詞

與圖聯系起來。(這是學生們做練習的情景)（以下是課堂練習內容）

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.學習新單詞

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

5.檢查單詞

1）個人或集體朗讀單詞。

2）做游戲（根據老師所給的圖片一人比劃另一人猜出這個單詞或一人用英語說出圖片的意思另一人 猜出這個單詞。（3組練習）

設計意圖：教材1.1中教學內容生詞量較大，平時又很少遇到，學習起來比較枯燥，難以記住。但用音樂將圖片連接起來，充滿激情的音樂營造了歡快的學習氣氛，使學生情緒高漲，同時又陶冶了學生的情操。說出已知的單詞和圖與詞連接的練習，可以展示學生自主學習的成果。讓學生聽著音樂，看著圖片，在不知不覺中學習了單詞，并自然而然地讓學生融于英語學習的情境中，大大激發(fā)了他們的學習興趣，又以游戲的形式檢查單詞，有趣的畫面，難忘的表演，吸引了學生的注意力加深了他們對單詞的印象。為后面的學習內容打下了基礎

在這個教學環(huán)境中，學生是活動的主體，教師只充當了“節(jié)目主持人”的角

色。

第二個環(huán)節(jié)：師生互動，學習探究

1.看海報，回答問題 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.聽錄音完成1.1練習（鞏固所學單詞）

3聽錄音完成1.2練習。

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.讓學生朗讀1.2和1.3的句子。學生通過觀察，討論，總結，歸納can的用法。設計意圖：

聽的環(huán)節(jié)是“輸入”的過程，帶著問題聽，讓學生在聽的過程中有的放矢，有效捕捉信息，同時又提醒學生注意觀察并發(fā)現需要注意的表達方式，為后面的語言實踐準備實用句型。這種讓學生在具體的語境中發(fā)現新句型的教學方法，能有效地提高學生分析問題和解決問題的能力，避免了傳統的教師為主體的抽象的語法說教，調動了學生思維積極性，給學生提供了提高觀察能力，分析能力和歸納總結能力的發(fā)展平臺。學生們以小組討論的方式進行觀察，探討，分析，歸納，得出正確結論。讓所有的學生都參與討論探究，這既體現了以學生發(fā)展為本的教育思想，又調動了學生的積極性與創(chuàng)造性。學生們自己發(fā)現的規(guī)律要比老師講解所學到的規(guī)律在腦海中的印象深刻得多，理解的透徹。第三個環(huán)節(jié)：合作交流，鞏固提高

1．看圖說話（i can / can?t… he can / can?t… they… we…

設計意圖：

在這個環(huán)節(jié)中，我向學生提供了 具有直觀性的圖畫，讓學生覺得有內 容說，新學的句型在這一活動中得到

充分運用和鞏固。

（學生練習時的情景）2．做鏈接游戲 4人一組。第一個同學說 i can swim.第二個同學說 i can?t swim, but i can skate 第三個同學說：i can?t skate, but i can do

the high jump.第四個同學說：i can?t do the high jump, but i can do the long jump.設計意圖：

變換語境操練是機械模仿進一步的發(fā)展，對語言運用的能力的要求又有所提高，有利于開發(fā)學生的創(chuàng)新能力和求異思維能力，這樣的活動增加了

趣味性，使緊張的氣氛得到緩解。3.采訪同學看誰能做：要求用句型 can you do…提問，用 i can…

根據我課前調查我寫了以下詞組

play basketball，sing well run fast, dance well, play the piano, run the 100-meter race.學生們可以下位子采訪，誰先找到這六位同學，誰得第一，并給與獎勵。我又讓能唱能跳的學生在班上即興表演，又一次掀起了高潮。

設計意圖：

新課程標準倡導主動參與，樂于探索，勤于思考，培養(yǎng)學生收集和處理語言信息的能力。通過這一環(huán)節(jié)的練習，不但學生的語言技能得到了提高，而且他們的情感態(tài)度和學習策略都得到了培養(yǎng)，同時他們的語言知識還得到了復習和鞏固。這樣的練習可以充分調動學生的參與熱情，激發(fā)學生的學習興趣。

4.讓學生用what can you do? 及本節(jié)課所學的句型編一個對話，內容是學生會體育部和文藝部招聘人員。（兩人一組）

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.設計意圖：

讓學生體驗不同的角色，參與實踐，合作交流，從而提高語言的運用能力。讓所有學生全面參與，使學生的思維一直處于積極的狀態(tài)，提高課堂教學

質量 教學反思：

新課標注重學生的情感因素，著力培養(yǎng)學生的學習興趣，激發(fā)學生的學習動機和培養(yǎng)他們熱愛生活的品質。在英語教學中適當運用游戲教學可使學生在玩中學，變無意注意為有意注意，使學生在游戲之中實實在在地進行語言信息交流，避免了枯燥的死記硬背，激發(fā)了學生的學習興趣，曾強了學生學好英語的信心和決心，使良好的英語學習心理素質在游戲之中逐漸培養(yǎng)起來。新課程標準從某種意義上說對老師提出了更高的要求，作為英語老師，我們要及時轉換自己的角色和觀念，做一名出色的節(jié)目主持人，組織好每一項課堂活動，把表演的機會給學生，讓學生成為真正的“主角”，讓學生時刻處在體驗，實踐，參與，合作與交流的活動中，使他們的語言技能，語言知識，情感態(tài)度，學習策略和文化意識等素養(yǎng)得到整體發(fā)展.

第二篇：情態(tài)動詞can的教學反思

教學的方式要以教學的任務和內容、學生的年齡特點和心理需求，靈活多變地加以應用。小學生容易注意力不集中，為了引起學生的注意力并激發(fā)學生的學習積極性，

在教學情態(tài)動詞can 的時候，教師畫出下列簡筆畫：

我邊畫簡筆畫邊說: 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.(畫出第一幅圖示并鼓勵學生說出動詞短語：play table tennis).I can play the piano.(畫出第二幅圖示并鼓勵學生說出動詞短語play the piano).I can stand on my head.(畫出第三幅圖示并鼓勵學生說出動詞短語stand on my head).然后我叫了五位學生，讓他們做動作來告訴大家。我又問：What can he /she do? 讓他們說出:I can…….引出另外五個短語：play football, swim, roller blade, ski,ride a horse.接著讓學生根椐學過的動詞短語用句型Ican ….I cannot….個自寫出自己會做的事情和不會做的事情.然后讓學生利用句型:What can I do? Can you…? Yes, I can.或No I can’t.互猜彼此會做的事情和不會做的事情。這樣可以讓學生所學語言產生興趣，從而激發(fā)學生的學習欲望調動學生的學習積極性。

這樣通過大量的、反復的、多種形式的操練，要求學生在量中求質，在速度中求準確。

我認為，為了有效地利用練習的時間，提高練習的效率，教師在組織練習時，要分秒必爭，爭取在有限的時間內，加大練習的強度和密度。

第五篇：情態(tài)動詞教案

情態(tài)動詞

【考綱解讀】

情態(tài)動詞與虛擬語氣有千絲萬縷的聯系，它們往往放在一起考查。在近年高考題中，對情態(tài)動詞的考查幾乎每年都有縱觀近幾年的高考題可以看出，高考對情態(tài)動詞的考查熱點依次是：（1）推測和可能性；（2）“情態(tài)動詞+have done”結構表示猜測或表示虛擬語氣；（3）shall, should, can, must表示特定語氣。尤其是對“情態(tài)動詞+have done”結構的考查頻率較高。試題的情景設置往往生動、真實，但考查的角度趨于細微化和綜合化，有效信息較為隱蔽，這就決定了情態(tài)動詞題是難題之一。情態(tài)動詞題每年都考，所以本專題在高考中的重要地位是顯而易見的。因而在復習中應引起高度重視，且依筆者之見，來年高考中對情態(tài)動詞考查的可能性依然非常大。【知識要點】

一、情態(tài)動詞的語法特征

1.情態(tài)動詞不能表示正在發(fā)生或已經發(fā)生的事情，只表示期待或估計某事的發(fā)生。2.情態(tài)動詞 除ought 和have 外，后面只能接不帶to 的不定式。3.情態(tài)動詞沒有人稱、數的變化，即情態(tài)動詞第三人稱單數不加-s。4.情態(tài)動詞沒有非謂語形式，即沒有不定式，分詞等形式。

二、情態(tài)動詞的基本用法 1.比較can 和be able to 1)can could 表示能力；可能(過去時用could)，只用于現在時和過去時(could)。be able to可以用于各種時態(tài)。

They will be able to tell you the news soon.他很快就能告訴你消息了。2)只用be able to中情況： 位于助動詞后； 情態(tài)動詞后；

表示過去某時刻動作時； 用于句首表示條件；

表示成功地做了某事時，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.戰(zhàn)爭爆發(fā)前，他就逃離歐洲了。

注意：could，在否定，疑問句中表示推測或懷疑。表示提出委婉的請求（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.他不大可能是壞人。2.比較may和might

1)表示允許或請求；表示沒有把握的推測；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 表示推測時，不表示時態(tài)。只是可能性比may 小。

2)may/might as well，后面接不帶to 的不定式，意為“不妨，還是……好”。You may(might)as well tell me the truth.你還是對我說實話好。3.比較have to和must

1)兩詞都是“必須”的意思，have to 表示客觀的需要，must 表示說話人主觀上的看法，即主觀上的必要。

My brother was very ill，so I had to call the doctor in the middle of the night.我弟弟病得很厲害，我只得半夜里把醫(yī)生請來。(客觀上需要做這件事)

He said that they must work hard.他說他們必須努力工作。（主觀上要做這件事）

2)have to有人稱、數、時態(tài)的變化，而must只有一種形式。

He had to look after his sister yesterday.昨天他不得不照看他的妹妹。3)在否定結構中：

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.你不必把此事告訴他。You mustn’t tell him about it.你一定不要把這件事告訴他。4.must表示推測

1)must用在肯定句中表示較有把握的推測，意為“一定”。

2)must表對現在的狀態(tài)或現在正發(fā)生的事情的推測時，must 后面通常接系動詞be 的原形或行為動詞的進行式。

You have worked hard all day.You must be tired.你辛苦干一整天，一定累了。（對現在情況的推測判斷）He must be working in his office.他一定在辦公室工作呢。比較：He must be staying there.他現在肯定在那里。He must stay there.他必須待在那里。

3)must 表示對已發(fā)生的事情的推測時，must 要接完成式。I didn’t hear the phone.I must have been asleep.我剛才沒有聽到電話，我想必是睡著了。

4)must表示對過去某時正發(fā)生的事情的推測，must 后面要接不定式的完成進行式。—Why didn’t you answer my phone call?

—Well，I must have been sleeping，so I didn’t hear it.5)否定推測用can’t。

If Tom didn’t leave here until five o’clock，he can’t be home yet.如果湯姆五點才離開這兒，他此時一定還未到家。5.表示推測的用法

can，could，may，might，must 皆可表示推測，其用法如下： 1)情態(tài)動詞+動詞原形

表示對現在或將來的情況的推測，此時動詞通常為系動詞。I don’t know where she is，she may be in Wuhan.我不知道她在哪兒，她可能在武漢。2)情態(tài)動詞+動詞現在進行時

表示對現在或將來正在進行的情況進行推測。

At this moment，our teacher must be correcting our exam papers.這時，我們老師想必在批改試卷。

3)情態(tài)動詞+動詞完成時表示對過去情況的推測。

We would have finished this work by the end of next December.明年12月底前我們很可能已完成這項工作了。The road is wet.It must have rained last night.地是濕的，昨天晚上一定下雨了。

4)情態(tài)動詞+動詞的現在完成進行時表示對過去正在發(fā)生事情的推測。Your mother must have been looking for you.你媽媽一定一直在找你。

5)推測的否定形式，疑問形式用can’t，couldn’t表示。

Mike can’t have found his car，for he came to work by bus this morning.邁克一定還沒有找回他的車，因為早上他是坐公共汽車來上班的。

注意：could，might表示推測時不表示時態(tài)，其推測的程度不如can，may。6.情態(tài)動詞+have+過去分詞

1)may(might)have+done sth.can(could)have+done sth.表示過去，推測過去時間里可能發(fā)生的事情。

Philip may(might)have been hurt seriously in the car accident.飛利浦在那場車禍中有可能傷的很嚴重。

2)must have+done sth.對過去時間里可能發(fā)生的事情的推測，語氣較強，具有“肯定”“諒必”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.本應該做某事，而事實上并沒有做。否定句表示“不該做某事而做了”。

He ought not to have thrown the old clothes away.（事實上已扔了。）ought to 在語氣上比should 要強。4)needn’t have done sth.本沒必要做某事 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，但我本沒有必要那么去做。天太熱了。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.我本想讀那本書，但我那時太忙了。7.should 和ought to

should 和ought to 都為“應該”的意思，可用于各種人稱。—Ought he to go?

—Yes.I think he ought to.表示要求，命令時，語氣由 should（應該），had better最好），must（必須）漸強。8.had better表示“最好”

had better 相當于一個助動詞，它只有一種形式，它后面要跟動詞原形。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.表示與事實相反的結果，意為“本來最好”。9.would rather表示“寧愿” would rather do 寧可干某事

would rather not do 寧可不干某事 would rather...than...寧愿……而不愿

還有would sooner，had rather，had sooner都表示“寧愿”“寧可”的意思。I would rather stay here than go home.=I would stay here rather than go home.我寧可待在這兒也不回家。

10.will和would

1)would like；would like to do=want to 想要，為固定搭配。Would you like to go with me?你想和我一塊兒去嗎？

2)Will you...? Would you like...?表示肯定含義的請求勸說時，疑問句 中一般用some，而不是any。

Would you like some cake?要蛋糕嗎？

3)否定結構中用will，一般不用would，won’t you是一種委婉語氣。Won’t you sit down?你不坐嗎? 11.情態(tài)動詞的回答方式

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.典型例題

1）---Could I borrow your dictionary?---Yes,of course,you____.A.might B.will C.can D.should 答案C.could表示委婉的語氣,并不為時態(tài).答語中of course,表示肯定的語氣,允許某人做某事時,用can和 may來表達,不能用could或might.復習：will 與you連用,用來提出要求或下命令.should與you 連用,用來提出勸告.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 將不,mustn't 禁止、不能.shouldn't 不應該.本題為不需要,不必的意思,應用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既可當作情態(tài)動詞,表請求、建議、也可作為實義動詞表“意愿、意志、決心”,本題表示決心,選B.12.比較need和dare

一、need表示“需要”或“必須”，作情態(tài)動詞時，僅用于否定句或疑問句中，在肯定句中一般用must,have to,ought to，或should代替。多用在否定式或疑問句中.1.Need I attend the meeting tomorrow?

我需要明天參加會議嗎? 2.You need not hand in the paper this week.這一周你不必交論文。

need 是一個情態(tài)動詞，他的用法完全和其他情態(tài)動詞一樣，但 need 還可當作實義動詞使用，這時 need 就象其他動詞一樣，有第三人稱，單復數，后面加帶 to 的動詞等特性。1.I need a bike to go to school.我上學需要一輛自行車。2.Do you need a dictionary? 你需要詞典嗎? 3.She needs a necklace.她需要一條項鏈。

needn't + have + 過去分詞 表示過去做了沒必要做的事情。You needn't have taken it seriously.這件事情你不必太認真。

二、Dare表示“敢”，Dare作情態(tài)動詞時，主要用于疑問句、否定句和條件從句中，一般不用在肯定句中。多用在否定或疑問句中。1.The little girl dare not speak in public.小女孩不敢在公眾面前說話。2.Dare you catch the little cat? 你敢抓小貓嗎? dare 除用作情態(tài)動詞外，更多的是當實義動詞使用，用法同實義動詞一樣，要考慮人稱，單復數，時態(tài)等。

1.Do you dare to walk in the dark? 你敢黑夜走路嗎？

2.He doesn't dare to tell the teacher what happened that day.他不敢告訴老師那天發(fā)生的事。

三、Dare和need常用作實義動詞，有時態(tài)、人稱和數的變化，所不同的是，作實義動詞時，在肯定句中，dare后面通常接帶to的不定式，在否定和疑問句中，dare后面可接帶to或不帶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 的被動含義：need，want，require，worth（形容詞）后面接doing，也 可以表示被動：need doing=need to be done Shall用于第一人稱,表示征求對方的意愿.如：What shall we do this evening? 2.Shall用于第一、第三人稱疑問句中,表示說話人征求對方的意見或向對方請示.如：Shall we begin our lesson? When shall he be able to leave the hospital? 3.Shall用于第二、第三人稱,表示說話人給對方命令、警告、允諾或威脅.如：You shall fail if you don't work harder.（警告）He shall have the book when I finish reading.（允諾）He shall be punished.（威脅）
