第一篇：情態(tài)動(dòng)詞can的教學(xué)設(shè)計(jì)

情態(tài)動(dòng)詞can的教學(xué)設(shè)計(jì) 發(fā)布者： 付賢彥

教學(xué)目標(biāo)：

1.知識(shí)目標(biāo)：掌握本課的大綱詞匯和情態(tài)動(dòng)詞can的用法。

2.能力目標(biāo)：1）能聽(tīng)懂會(huì)不會(huì)那些體育運(yùn)動(dòng)項(xiàng)目話題的有關(guān)的簡(jiǎn)單會(huì)話。

容。

教學(xué)內(nèi)容： 1.大綱詞匯sport, throw, race, field, 新課標(biāo)詞匯high jump, long jump, event, track

2.句型 he can / can?t …

教學(xué)重點(diǎn)： 用情態(tài)動(dòng)詞can表示會(huì)不會(huì)那些體育運(yùn)動(dòng)項(xiàng)目的句子

教學(xué)手段： 多媒體。

教學(xué)步驟

教學(xué)第一個(gè)環(huán)節(jié)： 創(chuàng)設(shè)情景，導(dǎo)入新課

1.將有關(guān)表示體育運(yùn)動(dòng)項(xiàng)目的圖片由運(yùn)動(dòng)員進(jìn)行曲連接起來(lái)，向

學(xué)生們展播，從而引出sports meeting和sports event詞匯。2.要求學(xué)生以brainstorm的方式說(shuō)出what sport they know 3.把學(xué)生已知和未知的有關(guān)體育運(yùn)動(dòng)項(xiàng)目的 圖片和單詞卡片給學(xué)生（4人一組）把詞

與圖聯(lián)系起來(lái)。(這是學(xué)生們做練習(xí)的情景)（以下是課堂練習(xí)內(nèi)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(xué)習(xí)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(gè)人或集體朗讀單詞。

2）做游戲（根據(jù)老師所給的圖片一人比劃另一人猜出這個(gè)單詞或一人用英語(yǔ)說(shuō)出圖片的意思另一人 猜出這個(gè)單詞。（3組練習(xí)）

設(shè)計(jì)意圖：教材1.1中教學(xué)內(nèi)容生詞量較大，平時(shí)又很少遇到，學(xué)習(xí)起來(lái)比較枯燥，難以記住。但用音樂(lè)將圖片連接起來(lái)，充滿激情的音樂(lè)營(yíng)造了歡快的學(xué)習(xí)氣氛，使學(xué)生情緒高漲，同時(shí)又陶冶了學(xué)生的情操。說(shuō)出已知的單詞和圖與詞連接的練習(xí)，可以展示學(xué)生自主學(xué)習(xí)的成果。讓學(xué)生聽(tīng)著音樂(lè)，看著圖片，在不知不覺(jué)中學(xué)習(xí)了單詞，并自然而然地讓學(xué)生融于英語(yǔ)學(xué)習(xí)的情境中，大大激發(fā)了他們的學(xué)習(xí)興趣，又以游戲的形式檢查單詞，有趣的畫(huà)面，難忘的表演，吸引了學(xué)生的注意力加深了他們對(duì)單詞的印象。為后面的學(xué)習(xí)內(nèi)容打下了基礎(chǔ)

在這個(gè)教學(xué)環(huán)境中，學(xué)生是活動(dòng)的主體，教師只充當(dāng)了“節(jié)目主持人”的角

色。

第二個(gè)環(huán)節(jié)：師生互動(dòng)，學(xué)習(xí)探究

1.看海報(bào)，回答問(wèn)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(tīng)錄音完成1.1練習(xí)（鞏固所學(xué)單詞）

3聽(tīng)錄音完成1.2練習(xí)。

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(xué)生朗讀1.2和1.3的句子。學(xué)生通過(guò)觀察，討論，總結(jié)，歸納can的用法。設(shè)計(jì)意圖：

聽(tīng)的環(huán)節(jié)是“輸入”的過(guò)程，帶著問(wèn)題聽(tīng)，讓學(xué)生在聽(tīng)的過(guò)程中有的放矢，有效捕捉信息，同時(shí)又提醒學(xué)生注意觀察并發(fā)現(xiàn)需要注意的表達(dá)方式，為后面的語(yǔ)言實(shí)踐準(zhǔn)備實(shí)用句型。這種讓學(xué)生在具體的語(yǔ)境中發(fā)現(xiàn)新句型的教學(xué)方法，能有效地提高學(xué)生分析問(wèn)題和解決問(wèn)題的能力，避免了傳統(tǒng)的教師為主體的抽象的語(yǔ)法說(shuō)教，調(diào)動(dòng)了學(xué)生思維積極性，給學(xué)生提供了提高觀察能力，分析能力和歸納總結(jié)能力的發(fā)展平臺(tái)。學(xué)生們以小組討論的方式進(jìn)行觀察，探討，分析，歸納，得出正確結(jié)論。讓所有的學(xué)生都參與討論探究，這既體現(xiàn)了以學(xué)生發(fā)展為本的教育思想，又調(diào)動(dòng)了學(xué)生的積極性與創(chuàng)造性。學(xué)生們自己發(fā)現(xiàn)的規(guī)律要比老師講解所學(xué)到的規(guī)律在腦海中的印象深刻得多，理解的透徹。第三個(gè)環(huán)節(jié)：合作交流，鞏固提高

1．看圖說(shuō)話（i can / can?t… he can / can?t… they… we…

設(shè)計(jì)意圖：

在這個(gè)環(huán)節(jié)中，我向?qū)W生提供了 具有直觀性的圖畫(huà)，讓學(xué)生覺(jué)得有內(nèi) 容說(shuō)，新學(xué)的句型在這一活動(dòng)中得到

充分運(yùn)用和鞏固。

（學(xué)生練習(xí)時(shí)的情景）2．做鏈接游戲 4人一組。第一個(gè)同學(xué)說(shuō) i can swim.第二個(gè)同學(xué)說(shuō) i can?t swim, but i can skate 第三個(gè)同學(xué)說(shuō)：i can?t skate, but i can do

the high jump.第四個(gè)同學(xué)說(shuō)：i can?t do the high jump, but i can do the long jump.設(shè)計(jì)意圖：

變換語(yǔ)境操練是機(jī)械模仿進(jìn)一步的發(fā)展，對(duì)語(yǔ)言運(yùn)用的能力的要求又有所提高，有利于開(kāi)發(fā)學(xué)生的創(chuàng)新能力和求異思維能力，這樣的活動(dòng)增加了

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

根據(jù)我課前調(diào)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(xué)生們可以下位子采訪，誰(shuí)先找到這六位同學(xué)，誰(shuí)得第一，并給與獎(jiǎng)勵(lì)。我又讓能唱能跳的學(xué)生在班上即興表演，又一次掀起了高潮。

設(shè)計(jì)意圖：

新課程標(biāo)準(zhǔn)倡導(dǎo)主動(dòng)參與，樂(lè)于探索，勤于思考，培養(yǎng)學(xué)生收集和處理語(yǔ)言信息的能力。通過(guò)這一環(huán)節(jié)的練習(xí)，不但學(xué)生的語(yǔ)言技能得到了提高，而且他們的情感態(tài)度和學(xué)習(xí)策略都得到了培養(yǎng)，同時(shí)他們的語(yǔ)言知識(shí)還得到了復(fù)習(xí)和鞏固。這樣的練習(xí)可以充分調(diào)動(dòng)學(xué)生的參與熱情，激發(fā)學(xué)生的學(xué)習(xí)興趣。

4.讓學(xué)生用what can you do? 及本節(jié)課所學(xué)的句型編一個(gè)對(duì)話，內(nèi)容是學(xué)生會(huì)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(shè)計(jì)意圖：

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

質(zhì)量 教學(xué)反思：

新課標(biāo)注重學(xué)生的情感因素，著力培養(yǎng)學(xué)生的學(xué)習(xí)興趣，激發(fā)學(xué)生的學(xué)習(xí)動(dòng)機(jī)和培養(yǎng)他們熱愛(ài)生活的品質(zhì)。在英語(yǔ)教學(xué)中適當(dāng)運(yùn)用游戲教學(xué)可使學(xué)生在玩中學(xué)，變無(wú)意注意為有意注意，使學(xué)生在游戲之中實(shí)實(shí)在在地進(jìn)行語(yǔ)言信息交流，避免了枯燥的死記硬背，激發(fā)了學(xué)生的學(xué)習(xí)興趣，曾強(qiáng)了學(xué)生學(xué)好英語(yǔ)的信心和決心，使良好的英語(yǔ)學(xué)習(xí)心理素質(zhì)在游戲之中逐漸培養(yǎng)起來(lái)。新課程標(biāo)準(zhǔn)從某種意義上說(shuō)對(duì)老師提出了更高的要求，作為英語(yǔ)老師，我們要及時(shí)轉(zhuǎn)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(xiàng)課堂活動(dòng)，把表演的機(jī)會(huì)給學(xué)生，讓學(xué)生成為真正的“主角”，讓學(xué)生時(shí)刻處在體驗(yàn)，實(shí)踐，參與，合作與交流的活動(dòng)中，使他們的語(yǔ)言技能，語(yǔ)言知識(shí)，情感態(tài)度，學(xué)習(xí)策略和文化意識(shí)等素養(yǎng)得到整體發(fā)展.

第二篇：情態(tài)動(dòng)詞can的教學(xué)反思

教學(xué)的方式要以教學(xué)的任務(wù)和內(nèi)容、學(xué)生的年齡特點(diǎn)和心理需求，靈活多變地加以應(yīng)用。小學(xué)生容易注意力不集中，為了引起學(xué)生的注意力并激發(fā)學(xué)生的學(xué)習(xí)積極性，

在教學(xué)情態(tài)動(dòng)詞can 的時(shí)候，教師畫(huà)出下列簡(jiǎn)筆畫(huà)：

我邊畫(huà)簡(jiǎn)筆畫(huà)邊說(shuō): 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(huà)出第一幅圖示并鼓勵(lì)學(xué)生說(shuō)出動(dòng)詞短語(yǔ)：play table tennis).I can play the piano.(畫(huà)出第二幅圖示并鼓勵(lì)學(xué)生說(shuō)出動(dòng)詞短語(yǔ)play the piano).I can stand on my head.(畫(huà)出第三幅圖示并鼓勵(lì)學(xué)生說(shuō)出動(dòng)詞短語(yǔ)stand on my head).然后我叫了五位學(xué)生，讓他們做動(dòng)作來(lái)告訴大家。我又問(wèn)：What can he /she do? 讓他們說(shuō)出:I can…….引出另外五個(gè)短語(yǔ)：play football, swim, roller blade, ski,ride a horse.接著讓學(xué)生根椐學(xué)過(guò)的動(dòng)詞短語(yǔ)用句型Ican ….I cannot….個(gè)自寫出自己會(huì)做的事情和不會(huì)做的事情.然后讓學(xué)生利用句型:What can I do? Can you…? Yes, I can.或No I can’t.互猜彼此會(huì)做的事情和不會(huì)做的事情。這樣可以讓學(xué)生所學(xué)語(yǔ)言產(chǎn)生興趣，從而激發(fā)學(xué)生的學(xué)習(xí)欲望調(diào)動(dòng)學(xué)生的學(xué)習(xí)積極性。

這樣通過(guò)大量的、反復(fù)的、多種形式的操練，要求學(xué)生在量中求質(zhì)，在速度中求準(zhǔn)確。

我認(rèn)為，為了有效地利用練習(xí)的時(shí)間，提高練習(xí)的效率，教師在組織練習(xí)時(shí)，要分秒必爭(zhēng)，爭(zhēng)取在有限的時(shí)間內(nèi)，加大練習(xí)的強(qiáng)度和密度。

第三篇：英語(yǔ)語(yǔ)法教學(xué)微課教案(情態(tài)動(dòng)詞can和could)

情態(tài)動(dòng)詞

【考綱解讀】

情態(tài)動(dòng)詞與虛擬語(yǔ)氣有千絲萬(wàn)縷的聯(lián)系，它們往往放在一起考查。在近年高考題中，對(duì)情態(tài)動(dòng)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(duì)情態(tài)動(dòng)詞的考查熱點(diǎn)依次是：（1）推測(cè)和可能性；（2）“情態(tài)動(dòng)詞+have done”結(jié)構(gòu)表示猜測(cè)或表示虛擬語(yǔ)氣；（3）shall, should, can, must表示特定語(yǔ)氣。尤其是對(duì)“情態(tài)動(dòng)詞+have done”結(jié)構(gòu)的考查頻率較高。試題的情景設(shè)置往往生動(dòng)、真實(shí)，但考查的角度趨于細(xì)微化和綜合化，有效信息較為隱蔽，這就決定了情態(tài)動(dòng)詞題是難題之一。情態(tài)動(dòng)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(jiàn)的。因而在復(fù)習(xí)中應(yīng)引起高度重視，且依筆者之見(jiàn)，來(lái)年高考中對(duì)情態(tài)動(dòng)詞考查的可能性依然非常大。【知識(shí)要點(diǎn)】

一、情態(tài)動(dòng)詞的語(yǔ)法特征

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

二、情態(tài)動(dòng)詞的基本用法 1.比較can 和be able to 1)can could 表示能力；可能(過(guò)去時(shí)用could)，只用于現(xiàn)在時(shí)和過(guò)去時(shí)(could)。be able to可以用于各種時(shí)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(dòng)詞后； 情態(tài)動(dòng)詞后；

表示過(guò)去某時(shí)刻動(dòng)作時(shí)； 用于句首表示條件；

表示成功地做了某事時(shí)，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(zhēng)爆發(fā)前，他就逃離歐洲了。

注意：could，在否定，疑問(wèn)句中表示推測(cè)或懷疑。表示提出委婉的請(qǐng)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(qǐng)求；表示沒(méi)有把握的推測(cè)；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(cè)時(shí)，不表示時(shí)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(duì)我說(shuō)實(shí)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(shuō)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(qǐng)來(lái)。(客觀上需要做這件事)

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

2)have to有人稱、數(shù)、時(shí)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(jié)構(gòu)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(cè)

1)must用在肯定句中表示較有把握的推測(cè)，意為“一定”。

2)must表對(duì)現(xiàn)在的狀態(tài)或現(xiàn)在正發(fā)生的事情的推測(cè)時(shí)，must 后面通常接系動(dòng)詞be 的原形或行為動(dòng)詞的進(jìn)行式。

You have worked hard all day.You must be tired.你辛苦干一整天，一定累了。（對(duì)現(xiàn)在情況的推測(cè)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(xiàn)在肯定在那里。He must stay there.他必須待在那里。

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

4)must表示對(duì)過(guò)去某時(shí)正發(fā)生的事情的推測(cè)，must 后面要接不定式的完成進(jìn)行式?！猈hy didn’t you answer my phone call?

—Well，I must have been sleeping，so I didn’t hear it.5)否定推測(cè)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(diǎn)才離開(kāi)這兒，他此時(shí)一定還未到家。5.表示推測(cè)的用法

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

表示對(duì)現(xiàn)在或?qū)?lái)的情況的推測(cè)，此時(shí)動(dòng)詞通常為系動(dòng)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(dòng)詞+動(dòng)詞現(xiàn)在進(jìn)行時(shí)

Mike can’t have found his car，for he came to work by bus this morning.邁克一定還沒(méi)有找回他的車，因?yàn)樵缟纤亲财噥?lái)上班的。

注意：could，might表示推測(cè)時(shí)不表示時(shí)態(tài)，其推測(cè)的程度不如can，may。6.情態(tài)動(dòng)詞+have+過(guò)去分詞

1)may(might)have+done sth.can(could)have+done sth.表示過(guò)去，推測(cè)過(guò)去時(shí)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(chǎng)車禍中有可能傷的很嚴(yán)重。

2)must have+done sth.對(duì)過(guò)去時(shí)間里可能發(fā)生的事情的推測(cè)，語(yǔ)氣較強(qiáng)，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(yīng)該做某事，而事實(shí)上并沒(méi)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(shí)上已扔了。）ought to 在語(yǔ)氣上比should 要強(qiáng)。4)needn’t have done sth.本沒(méi)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(méi)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(shū)，但我那時(shí)太忙了。7.should 和ought to

should 和ought to 都為“應(yīng)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(shí)，語(yǔ)氣由 should（應(yīng)該），had better最好），must（必須）漸強(qiáng)。8.had better表示“最好”

had better 相當(dāng)于一個(gè)助動(dòng)詞，它只有一種形式，它后面要跟動(dòng)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(shí)相反的結(jié)果，意為“本來(lái)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(qǐng)求勸說(shuō)時(shí)，疑問(wèn)句 中一般用some，而不是any。

Would you like some cake?要蛋糕嗎？

3)否定結(jié)構(gòu)中用will，一般不用would，won’t you是一種委婉語(yǔ)氣。Won’t you sit down?你不坐嗎? 11.情態(tài)動(dòng)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(yǔ)氣,并不為時(shí)態(tài).答語(yǔ)中of course,表示肯定的語(yǔ)氣,允許某人做某事時(shí),用can和 may來(lái)表達(dá),不能用could或might.復(fù)習(xí)：will 與you連用,用來(lái)提出要求或下命令.should與you 連用,用來(lái)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(yīng)該.本題為不需要,不必的意思,應(yīng)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(dāng)作情態(tài)動(dòng)詞,表請(qǐng)求、建議、也可作為實(shí)義動(dòng)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(dòng)詞時(shí)，僅用于否定句或疑問(wèn)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(wèn)句中.1.Need I attend the meeting tomorrow?

我需要明天參加會(huì)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(gè)情態(tài)動(dòng)詞，他的用法完全和其他情態(tài)動(dòng)詞一樣，但 need 還可當(dāng)作實(shí)義動(dòng)詞使用，這時(shí) need 就象其他動(dòng)詞一樣，有第三人稱，單復(fù)數(shù)，后面加帶 to 的動(dòng)詞等特性。1.I need a bike to go to school.我上學(xué)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(xiàng)鏈。

needn't + have + 過(guò)去分詞 表示過(guò)去做了沒(méi)必要做的事情。You needn't have taken it seriously.這件事情你不必太認(rèn)真。

二、Dare表示“敢”，Dare作情態(tài)動(dòng)詞時(shí)，主要用于疑問(wèn)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(wèn)句中。1.The little girl dare not speak in public.小女孩不敢在公眾面前說(shuō)話。2.Dare you catch the little cat? 你敢抓小貓嗎? dare 除用作情態(tài)動(dòng)詞外，更多的是當(dāng)實(shí)義動(dòng)詞使用，用法同實(shí)義動(dòng)詞一樣，要考慮人稱，單復(fù)數(shù)，時(shí)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(shí)義動(dòng)詞，有時(shí)態(tài)、人稱和數(shù)的變化，所不同的是，作實(shí)義動(dòng)詞時(shí)，在肯定句中，dare后面通常接帶to的不定式，在否定和疑問(wèn)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(dòng)含義：need，want，require，worth（形容詞）后面接doing，也 可以表示被動(dòng)：need doing=need to be done Shall用于第一人稱,表示征求對(duì)方的意愿.如：What shall we do this evening? 2.Shall用于第一、第三人稱疑問(wèn)句中,表示說(shuō)話人征求對(duì)方的意見(jiàn)或向?qū)Ψ秸?qǐng)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(shuō)話人給對(duì)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）
