第一篇：情態動詞need的用法
情態動詞need用法小結
一、NEED與句子類型
(本條可參照ANY的用法。) NEED可用于：
1.否定句/含有否定意義的句子 1)否定句
含not/hardly/never/nobody等詞語。 I needn’t say anything. He need hardly advise me. You never need tell me this or that. Nobody need help me. I don’t think he need come.(否定轉移)
注：NEEDN’T的意思其實有三種，即不必要/不一定/不應該，視具體語境而定。 2)含有否定意義的句子
含only/but/all/before/than等詞語。 He need only wait here. You need but consider the matter to understand its importance. That’s all that need be said.
Do not stay longer than you need. There was another hour before I need go out into the cold. 2.疑問句/表示疑問的從句 1)疑問句(包括否定疑問句) Need he say it again? 2)表示疑問的從句
I wonder whether/if I need see her. 3.條件句
含if/unless等詞。
If he need come, he will. 本條要點簡單概括起來就是，NEED不能用于肯定句。以下的各種用法也遵循這條規則。
二、NEED與時態 1.現在時
NEED常用于現在時。 You needn’t stay. 2.將來時
You needn’t have your blood pressure taken tomorrow. 3.過去時
NEED的過去式仍然是NEED。 1)過去時間由一過去時間狀語表示 He need not come yesterday. 2)過去時間由另一過去時動詞表示。 All he need do was to inquire. It was clear that he need never trouble to get up at seven again. I told him he needn’t be in a terrible fix. 注：表示過去的NEED常用于間接引語中。 (本條可參照must的用法)
三、NEED與虛擬語氣 1)NEED用于虛擬條件句
(本條可參照虛擬條件句的構成及用法。) If money were useless, we need not struggle for it. If you had been careful enough, you need not have suffered. 注：本條用法較為少見。
2)NEED單獨使用：NEEDN’T HAVE DONE (本條可參照SHOULDN’T HAVE DONE的用法。) You need not have worried. 注：NEED HAVE DONE的形式較為少見
Need you have scolded him so severely for his bad work? He had done his best.(否定意味)
He need have gone and sent that letter in person.(實際上沒有做)
四、NEED與推測
NEEDN’T表示“不一定”。 (本條可參照must/can的用法。) 1) NEEDN’T+BE
It needn’t be hot in Florida now. 對比：
It can’t be hot in Florida now.(一定不) It must be hot in Florida now.(一定) 2) NEEDN’T+HAVE DONE
He need not have seen much of the world, though he is an old man. 對比：
He can’t have seen much of the world, for he is just a little boy. He must have seen much of the world, for he has been traveling so widely.
五、NEED與問句 1)反意疑問句的構成 You needn’t go, need you? 2)答句的構成 --- Need he go? --- Yes, he must/has to/needs to. --- No, he needn’t.
(本條可參照must的用法)
六、情態動詞NEED與實義動詞NEED 1)使用范圍
作為實義動詞的NEED有人稱、數和時態的變化，使用范圍更為廣泛，不受句子類型和時態的限制。在肯定句、過去時和將來時的句子中，一般使用作為實義動詞的NEED。
He needs to see a doctor straightaway.(此處needs to不能換做need，因為本句是肯定句)
Will he need to start earlier? 注：
NEED TO BE DONE與NEED DOING可以互換，后者更為常用(這里的NEED均為實義動詞)。 2)含義差別
NEEDN’T HAVE DONE與DIDN’T NEED TO DO表示“不必要”的時候，在意義上有所差別，前者表示“本不必做„„”，實際上已經做了(NEED為情態動詞);后者單純地表示“不必做„„”(NEED為實義動詞)。
第二篇：情態動詞can的教學設計
情態動詞can的教學設計 發布者： 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
教學第一個環節： 創設情景，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
在這個教學環境中，學生是活動的主體，教師只充當了“節目主持人”的角
色。
第二個環節：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：
聽的環節是“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展為本的教育思想，又調動了學生的積極性與創造性。學生們自己發現的規律要比老師講解所學到的規律在腦海中
的印象深刻得多，理解的透徹。 第三個環節：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：
在這個環節中，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展，對語言運用的能力的要求又有所提高，有利于開發學生的創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，培養學生收集和處理語言信息的能力。通過這一環節的練習，不但學生的語言技能得到了提高，而且他們的情感態度和學習策略都得到了培養，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，激發學生的
學習興趣。
4. 讓學生用what can you do? 及本節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，提高課堂教學
質量 教學反思：
新課標注重學生的情感因素，著力培養學生的學習興趣，激發學生的學習動機和培養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，情感態度，學習策略和文化意識等素養得到整體發展.
第三篇：情態動詞教案
情態動詞
1. 概念: 情態動詞: 表示說話者的某些觀點或態度的詞語.如 “能” , “或許” , “必須” , “需要” , “應該” 等. 2. 情態動詞主要有: can, may, must, need, should, … 這些情態動詞后面 + 動詞原形. 3. 用法

---Can you play basketball ? 你會打籃球嗎? --- Yes, I can. / No, I can’t. 是的, 我會. / 不, 我不會.
⑵ 表示懷疑、猜測，常用 be 連用, 放在否定句和疑問句中。如：
eg: He can’t be in the room. 他一定不在房間里.

第四篇：情態動詞小結
情態動詞有：can(could)， may(might)， must，have to, shall(should)，will(would)，need, dare, ought to等。 一. 情態動詞can, may, must用法 ㈠基本用法 1. can ⑴ 會，能夠 --Can you swim? --Yes, I can. --No, I can?t. ⑵ 口語中代替may. You can (may) park here. 你可以把車停在這里。(許可) 2. may允許，許可 --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必須 --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作為情態動詞，通常用在否定句和疑問句中。)
1 注意一：can 與be able to 都可以表示“能力”，區別是： ⑴ can只有現在和過去兩種形式
I can play the piano. She couldn?t play the piano when she was a little girl. ⑵ be able to ① 有更多的形式和時態
We shall/will be able to finish the work next week. I haven?t been able to find the book. ② 指具體一次活動
I can swim but I am not able to cross the rough sea. 有時兩者可以互換: 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 作為can的過去式，表示過去的能力。
When I was young I could climb any tree in the forest. 這時也可用was(were)able to ⑵ 用來代替can，婉轉地提出請求，想法，建議等?；卮疬@種情況下could引導的一般疑問句時，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(駕照). ③ We mustn?t be late, must we?
(與第4頁對比，此must不表猜測,兩回事。) 注意四：must的過去式是must，常用 had to 代替。 I had to see the dentist. 注意五：must 和 have to 都可以表示必須，但must表示說話人的主觀看法，have to表示客觀需要。 You must say sorry to me for that. You have to drive quickly, we have little time. 注意六：May+動詞原形表“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 疑問句：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”，“也許”，“可能” It may be Jenny.
3 3. must表示“可能性”，只能用于肯定句，表推測：“一定是”，“準是”，“必是”，“必定”。
It must be Jenny. 小結表示“可能性”：
疑問句：只能用can 否定句：cannot(can?t)“不可能”(反義詞是must“準是”) may not“可能不”
肯定句：may “大概”
must“準是”(反義詞是can?t) 注意一: 在表示“可能性”時，凡是對過去事物的猜測，不管是疑問..句，否定句還是肯定句，都要用完成時。 ...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 現在或將來的可能性。若表示對過去事物 .... 的猜測，則用完成時。 ③ He may come today.(tomorrow) He might come today.(tomorrow) (might語氣更不肯定，不是may的過去時) ④ She might have called for help.她可能大聲喊“救命”了。 請翻譯下里句子：
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表示猜測時的反義疑問句
⑴ “must be +表語”的結構，must表示肯定猜測時，含有“準是”，“勢必”，“一定”等意義時，反義疑問句用“isn?t/aren?t+主語” They must be hungry after the long walk, aren?t they? ⑵ “must have done” 表示猜測時，反義疑問句用“haven?t/hasn?t +主語”或“didn?t+主語”
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? ........解題秘笈：① 把must去掉 ② 找時間狀語 ③ 重新組成一新句子 ④ 按新句子的時態造反義疑問句
① You must have been to Beijing, ___ __?
去掉must;無時狀;重組成You have been to Beijing; 故答案為：haven?t you ② You must have finished your homework yesterday, .........___ __?去掉must;時狀為yesterday; 重組成 You finished your homework yesterday; 故答案為：didn?t you 二.情態動詞need的用法
⑴ need 表示“需要”，“必需”。作為情態動詞，通常用在否定句和疑問句中。
① He needn?t pay for it.( 情態動詞)
