情態動詞can教學反思范文第1篇
一、表示能力
例1.______your American friend eat with chopsticks? (2010山西)
———Yes, but he can’t use them well.
A.Can B.Should C.Must
Mean95%Confidence Interv () (I) grades (J) grades Mean Difference Std.Error Sig. (a) 95%Confidence Interv for Difference (a) 【解析】:此題意思是“———你的美國朋友會用筷子吃飯嗎?———會, 但他用得不是很好”。在此語境中, can表示能力, 故選A。can表示能力時, 只用于現在時和過去時。其否定式是can not/can’t;過去式是could (否定式為could not/couldn’t) 。又如:
2.Trees______fight air pollution.They are natural air conditioners. (2010沈陽)
A.should B.must C.need D.can
【辨析】：can/could與be able to的區別?！敬鸢浮緿。
例3.If it were not for the fact that she___sing, I would invite her to the party.
A.couldn’t B.shouldn’t C.can’t D.might not
例4.I talked for a long time, and in the end I_______make he believe me.
A.could B.can C.must D.was able to
【解析】：例3中“她不會唱”是指能力，所以選C;而例4意為：我說了好長時間，最終使他相信了我的話。雖然句中有“能”的意思，但它表示“經過努力設法做成了某事”，而非能力，故選D。was/were able to(=managed to do sth.)。由此說來，can表示一般能力，而be able to常用來表達在某件事情中所表現出來的能力，尤指克服困難完成了某事。
二、表示推測
例5.———Look at that girl!Is it Susan?(2010武漢)
———No, it____be her.She has gone back to her hometown.
A.mustn’t B.can’t C.needn’t D.wouldn’t
【解析】：此題意為“———看那個女孩，是蘇珊嗎?———肯定不是她，她已經回家鄉了”。此語境表示確有把握的否定推測，故選B。can表示推測時，常應用于否定句，表示確有把握的否定推測，也可用于疑問句。
【辨析】：1.can與must的區別
例6.———The lake is said to be dry.Is that true?(2010成都)
———It%%%.Look, some kids are swimming in it.
A.must be true B.can’t be true C.may not be true
例7.You______ be tired after playing sports for a long timewithout a rest.(2010四川巴中)
A.must B.need C.can’t
【解析】：例6中“some kids are swimming in it”說明“湖干涸了”這句話肯定不是真的，表示確有把握的否定推測，選B。例7中“a long time”和“without a rest”表明“體育運動之后你肯定累”此語境表示確有把握的肯定推測，選A。由此可見，表示確有把握的推測時，must應用于肯定句，而can應用于否定句。即must的否定式為can’t。
2.can與could的聯系
先看下面三個例子：
例8.———Mr Smith must have been to your home this morning. (2010無錫)
———No, he______, because he didn’t know my address.
例9.Jack______yet, otherwise he would have telephoned me.
A.mustn’t have arrived B.shouldn’t have arrived
C.can’t have arrived D.need not have arrived
例10.I don’t know when the guests will be here.They_______ar rive at any time.
A.shall B.need C.must D.could
A.couldn’t B.can’t C.mustn’t D.may not
【解析】：例8中“he didn’t know my address”表明史密斯先生肯定沒去我家，語氣委婉，故用couldn’t have been表示，由于答語又是省略句，省略了have been，故選A。例9意為“杰克肯定還沒來，否則他會給我打電話”，選C。例10的意思是“他們隨時都可能來”此語境表示“可能做了某事(可能性較小)”，選D。
can用于否定句(或疑問句)表示確有把握的否定推測，而could表推測時，既可用于否定句(或疑問句)，表示確有把握的否定推測(語氣較委婉);也可用于肯定句，表示一種把握性不大的推測。
三、表示請求幫助或允許
例11.———____you turn down your radio, please? (2010北京)
———Yes, I can.
A.May B.Need C.Must D.Can
【解析】：這是一個表示請求幫助的例子，故選D.can。can could表示請求幫助(或允許)時，肯定回答用can，否定用can’t。
【辨析】：can/could與may的聯系
例12.———______I use your ruler, Lingling?(2010桂林)
———Sure.Here you are.
A.May B.Would C.Need D.Must
例13.———Could I use your dictionary?(2010蕪湖)
———Yes, you______
A.can B.could C.need D.should
【解析】：can, could和may都可表示請求允許。can語氣一般，could/may比較禮貌。對于can/could的回答，一般是can/can’t，不可用could，而對may的回答，則很靈活：可以用may/may no或can/can’t，也可以用其他方式以示客氣，如“Yes, please./Sure/Certainly.”等;但表示“禁止”時，則常用must not/mustn’t。故例12選A.May，例13選A.can。
四、表示可能性
例14.It is usually warm in my hometown in March, but it_____be rather cold sometimes. (2009蘇州)
A.must B.can C.should D.would
【解析】：答案選B。can用于肯定句表示一種理論上或客觀上的可能性，并不涉及是否真的會發生，翻譯為“時而可能/有時候會……”。
五、表示疑惑或驚訝
例15.Mr Bush is on time for everything.How________it be that he was late for the opening ceremony?
A.can C.should C.may D.must
情態動詞can教學反思范文第2篇
第一,基于語境視角下的初中英語語法知識的呈現。
語法知識的呈現是語法教學的第一步,為了能夠幫助學生盡快地熟悉相關的語法點,并且愿意參與到教師所設計的課堂環節,教師可以在呈現環節利用相關的語境進行輔助。具體來看,教師可以通過為學生展示圖片的方式來創設語境,也可以通過播放英文歌曲來激發學生的情感體驗,或者是播放相關的視頻等幫助學生盡快融入到相關的話題和語境中去。比如說,在呈現情態動詞can的用法的教學階段中,如果教師只是死板地將相關的用法板書到黑板上,并要求學生筆記并記憶,英語課堂將是沉默的,語法教學也是低效的。反之,如果教師能夠在呈現情態動詞can的階段為學生播放一則動畫,動畫內容是關于各種動物的體育才能,如“貓會爬樹”,“鴨子會游泳”等等,將會極大地調動學生的積極性,吸引他們的注意力。這時,教師可以這樣指導學生:“Boys and girls, now please watch the English video carefully to get what these animals can do. After that,you should tell me what they can do using the sen-tence pattern‘it can + verb’.”這樣,學生便可以在觀看動畫片的基礎上,在教師的引導下,用英語說出“Theduck can swim. The cat can climb trees.”等運用了情態動詞can的句子。也就是說,在這一教學環節中,教師充分抓住了學生的年齡特點和興趣愛好,通過動畫片的方式為學生創設出了進行語法學習的生動語境,從而能夠幫助學生在輕松的氛圍中用心感悟和體驗。
第二,基于語境視角下的初中英語語法知識的練習。
為了能夠有效提高初中英語語法教學的效率,幫助學生在生動的環境中對相關的語法知識進行練習,在初中英語語法知識的練習階段,教師也可以為學生設法創設出相關的語境。通過這種方式,便可以有效地打破傳統的英語語法課堂上進行機械訓練的模式或者進行題海戰術的模式,讓每一位學生都能夠主動地參與到課堂活動中去。具體來看,在練習環節,教師可以通過講英語故事的方式為學生創設一定的語境,或者指導學生在進行相關會話的基礎上進行語法知識的訓練等等?？傊?這樣的活動必須是學生愿意參與的,這樣的課堂必須是以學生為主體的。比如,在對情態動詞must的基本用法進行練習的這一環節中,教師可以首先指導學生利用頭腦風暴的方式,思考自己在家或者在學校有哪些規則是必須遵守的。待創設了這一語境后,教師便可以要求每一個學生用“I must do something.”這一句型進行造句,表達自己必須遵守的一些規則,如“I must domy homework firstly at home.”及“I must keep quiet in the classroom.”等等。
第三,基于語境視角下的初中英語語法知識的運用。
其實,在初中英語教學中,學習語法知識的最終目的還是為了運用,即為了能夠幫助學生將相關的語法知識運用到具體的實踐中。為了培養學生將語言知識轉化為一定的語言能力,教師也應該在一定的語境視角下指導學生對初中英語語法知識點進行有效地運用。比如,在對情態動詞can進行運用的階段,教師可以通過講述的方式或者圖片展示的方式為學生設置一個學校藝術俱樂部進行招聘的語境。在此基礎上,教師便要求學生以小組為單位,組長作為招聘者,而其他同學作為應試者,利用“I can do something.”的句型來向主考官展示自己的才能,從而能夠贏得主考官的青睞,順利加入藝術俱樂部。在這一語境中,學生便可以真正地將自己融入到招聘這一情景中去,并且能夠主動地利用目標句型進行互相交流。在這樣的語法課堂上,不僅語言知識可以真正地轉化為語言能力,而且學生的積極性被極大地調動了起來。在他們的心目中,這樣的環境也許并不是在語法課上,而是在真正的招聘現場中。

情態動詞can教學反思范文第4篇
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.

eg: He can’t be in the room. 他一定不在房間里.
⑶ 表示請求或允許, 多用于口語中, 意為”可以”, 相當于 may. 如:
eg: You can go now. 你現在可以走了.
② could ⑴ 是can 的過去式, 表示過去的能力. 如:
eg: I could swim when I was a child. 當我還是一個小孩子的時候我就會游泳了.
⑵ couldn’t: “不能” 用could 提問肯定和否定回答分別用 could, 和 couldn’t.

2). couldn’t +have + PP表示本來不能做到，但已經做到了。 She could not have covered the whole distance, but in fact she arrived ahead of time.

2.can + have + PP 表示對過去的推測(限于問句中) Can she have said so? 他可能這樣說嗎?
3.can’t + have + PP 表示對過去的否定推測 He cannot have said such a foolish thing.
情態動詞表推測的反意疑問句
情態動詞表推測的反意疑問句，簡單來說，就是以情態動詞后的時態為淮，如句子里有明確的時間狀語，則以其為準。以 must 為例：
eg. 1. You must be hungry now, aren’t you?
2. He must be watching TV , isn’t he ?
3 Tom must have lived her for a long time, hasn’t he ?
4. She must have arrived yesterday, didn’t she?
