單元整體說明(一)單元教材分析本單元的核心話題是描述動物和表達個人喜好,以及句式why do you like…? Because…。這也是本單元的教學重點。通過本單元的學習,學生應能較流利地運用所學詞匯和句型描述動物,表達個人喜好。(二)單元知識結構1.詞匯動物名稱 tiger, elephant, koala, dolphin, etc.詞匯描述性形容詞: smart, cute, ugly, clever, shy, etc.國家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)單元整體目標1.Master the vocabulary2.Master and use: Why do you like koalas? Because they am cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(四)單元教學重難點一覽(五)單元學情分析學生此前已經(jīng)學過由why, where, what 引導的特殊疑問句句型,具有了學習本單元知識的認知前提。形形色色的動物能激發(fā)學生的好奇心,產(chǎn)生了解它們的欲望,這有利于本單元知識的教學和學生學習興趣的培養(yǎng)。

"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!歡迎你!請做一下自我介紹。認識一下你的新同學?!蓖ǔT谡n上老師會這樣說。你會說什么呢?“噢,不!”與陌生人談話太困難了。但是這也很有意思,并且你還能交到朋友。你該怎么做呢?閑聊。閑聊指得是禮貌的對話?!巴蹰且粋€很棒的乒乓球運動員,不是嗎?”“我希望自己能認識她,你呢?“今年的雨水很多,不是嗎?”反意疑問句是一種禮貌用語。為了使得談話成功,你應該知道怎樣去進行閑聊。你還應該知道與不同的人該談論什么樣的話題。認真的學習這個單元吧,下次在英語課上,你會發(fā)現(xiàn)與大家展開談話是一件很容易的事情,不信我們來試試。)

Don’t fight. =You can’t fight. (板書,教讀)教師把這些句子板書在黑板上,并請學生大聲整齊地讀祈使句和“can’t”句型,并讓學生注意兩種句型表達形式的不同和轉換,“Don’t …=You can’t…”;并對學生說:These are our school rules. (板書,教讀) You can’t break the school rules.

教材分析1、教材地位作用本單元圍繞著學習情態(tài)動詞can 的用法,來表達自己在某一方面所具有的能力。2、教學目標(知識目標、能力目標)(1)知識目標:復習情態(tài)動詞can 的用法。(2)能力目標:通過學習can ,達到能靈活談論自己的喜愛與特長,培養(yǎng)一種群體意識。3、重點和難點:(1)重點:情態(tài)動詞can的一般問句的用法。(2)難點:利用上下文語境及略讀技巧。二、教法:讓學生默讀課文(限時),讓學生在短時內抓住課文的重點,劃出關鍵詞,從中親自感受一下略讀的技巧,然后老師加以指導。三、學情與學法針對學生在不理解情態(tài)動詞can 的一般問句的情形下,反復閱讀課文,從而加深對本單元前兩頁所學can用法的印象,從中真正感悟can的用法.

教師準備利用錄音使學生學習一些物品名詞,并引導學生進行Pair work,學會詢問“What’s this? It's a … . How do you spell watch? W-A-T-C-H.”;引導學生寫“尋物啟事”和“失物招領”,畫圖猜測物品,鞏固所學內容,培養(yǎng)學生動腦、動手的能力及拾金不昧的精神和助人為樂、團結友愛的品德。學生準備學習一些物品名詞,了解寫尋物啟事和失物招領的內容和格式。1. Warming up考慮到大多數(shù)學生以前學過一部分單詞,可以以猜謎語競賽的形式導出本課內容. 以pencil為例:Step1: 說出謎面, 可以用漢語解釋.Our little JohnHas a wooden shirt on, And a long, sharp nose.He leaves his mark wherever he goes.接著教師畫一件物品如:baseball 問學生:What’s this? 讓學生使用句型 Is this a/an…?進行猜測。2. Group work學生分成四人或六人小組,將本單元的單詞畫出來加以猜測并評出最佳圖畫和最佳猜詞者。3. Read ,circle and write1) Ask students to look back at page 10 . Have students read the list of the words . 2) Look at the Section B 3a . 3) Check the answers by having one student read his or her circled answers .

語言知識:Where is/are-----? Is it /Are they on/in/under-----? Yes, it is. / No, it isn’t.Yes, they are./ No, they aren’t.任務二:尋寶大行動活動目的:通過創(chuàng)設貼近生活的語言情景,學生自由選擇所學的語言知識進行交流,培養(yǎng)學生綜合運用語言的能力?;顒舆^程:學生課前把自己最喜歡的一件東西收藏起來。以小組為單位,詢問其他組員把寶物放在什么地方。規(guī)定時間內找到寶物最多者獲勝。語言知識:Where is/are-----? Is it /Are they on/in/under-----? Yes, it is. / No, it isn’t.Yes, they are./ No, they aren’t.任務三:找差別活動目的:培養(yǎng)學生用英語思維的判辨能力,并對學生滲透德育教育:應該養(yǎng)成良好的生活習慣,保持房間干凈整潔?;顒舆^程:學生看兩幅相似的圖片,圖片中有一些相同的物品,但所放的地點卻不一樣。以小組為單位,輪流詢問有關物品所在的位置。學生記錄下兩幅圖片中物品位置的不同,并在班上匯報自己小組得出的結果。

1、利用插圖或實物卡片讓學生找出在預備篇中所學的單詞,然后教師引導學習打招呼和介紹自己、詢問他人姓名的基本句型。2、讓學生聽1a、1b對話,練習對話并模仿對話,結識班級的其他同學Step4 Practice師生互動(角色扮演) 讓學生進行角色扮演1c、2c的對話,每兩人一組,編對話,這個步驟主要是對1a-2b的內容進行鞏固。Step5 聽說活動(句型操練)1.播放2a部分的錄音讓學生聽,引導學生通過聽對話熟悉人名,完成2a,2b部分的教學任務。2.引導學生重復他們所聽到的,模仿對話結識班級的其他同學,完成2c部分的教學任務。3.概括語法點Step6 知識拓展 引導學生閱讀3a圖中的名和姓,了解有關中外姓名的文化知識差異;從3a中給自己選一個姓、名,然后調查其他同學的姓、名,完成3b的任務。Step7 Conclusion復習本課重難點,鞏固知識。Step8 Homework讓學生在課后運用所學單詞句型進行對話 練習。

二、說教學目標:由于本單元的五個話題都涉及到了不同的條件下所產(chǎn)生的各種結果。所以我確定的本課時的教學目標是:通過談論圖片和身邊常見的話題,學會if引導的條件狀語從句的用法。即用if條件狀語從句作出假設,用will來談論結果。三、說教學重點:一方面,由于本單元的話題是談論結果,那么在不同的情境下其結果也會不一樣,所以根據(jù)不同的情境來推測并談論各種結果是個重點。另一方面,因為學生沒有一個好的語言氛圍,所以我側重于聽力和口語的培養(yǎng),多創(chuàng)設情境能讓學生發(fā)揮想象,以此激發(fā)他們的學習興趣,。四、說教學難點學生容易記住主句用一般將來時態(tài),從句用一般現(xiàn)在時態(tài),但在判斷主句、從句方面容易混淆,因此,我將正確使用主句從句的時態(tài)定為本課時的難點。

1. 教材的地位及作用:本單元圍繞談論過去的經(jīng)歷,學習使用現(xiàn)在完成時態(tài)。通過對學生們喜聞樂見的一些娛樂場所(fun places)的描述,反復運用句型Have you ever been to…? I’ve never been to…. 來激發(fā)他們使用本單元所學單詞的興趣。教材中提供的所有活動都以現(xiàn)在完成時態(tài)為中心,通過一系列的聽、說、讀、寫的訓練,來加深對現(xiàn)在完成時態(tài)的理解,明白英漢兩種在結構及表達方法的一些異同點。從而提高他們運用所學語言的綜合能力。2. 教材的結構本單元分Section A 和Section B 兩部分。Section A 中通過所設計的各項任務呈現(xiàn)了兩篇聽力課文和一篇閱讀理解。Section B則安排了一篇聽力和兩篇小短文,用以加強對目標語言的理解。Self Check 部分是用來檢查學生對本單元所學目標語言的綜合運用能力。單元后的語篇訓練旨在通過目標語言培養(yǎng)學生的閱讀理解能力,掌握一些基本的閱讀技巧。3. 教學目標(知識目標、能力目標、情感目標)

2.如何找一條線段的黃金分割點,以及會畫黃金矩形.3.能根據(jù)定義判斷某一點是否為一條線段的黃金分割點.Ⅳ.課后作業(yè)習題4.8Ⅴ.活動與探究要配制一種新農藥,需要兌水稀釋,兌多少才好呢?太濃太稀都不行.什么比例最合適,要通過試驗來確定.如果知道稀釋的倍數(shù)在1000和2000之間,那么,可以把1000和2000看作線段的兩個端點,選擇AB的黃金分割點C作為第一個試驗點,C點的數(shù)值可以算是1000+(2000-1000)×0.618= 1618.試驗的結果,如果按1618倍,水兌得過多,稀釋效果不理想,可以進行第二次試 驗.這次的試驗點應該選AC的黃金分割點D,D的位置是1000+(1618-1000)×0.618,約等于1382,如果D點還不理想,可以按黃金分割的方法繼續(xù)試驗下去.如果太濃,可以選DC之間的黃金分割 點 ;如果太稀,可以選AD之間的黃金分割點,用這樣的方法,可以較快地找到合適的濃度數(shù)據(jù).這種方法叫做“黃金分割法”.用這樣的方法進行科學試驗,可以用最少的試驗次數(shù)找到最佳的數(shù)據(jù),既節(jié)省了時間,也節(jié)約了原材料.●板書設計

方法三:一個同學先畫兩條等長的線段AB、AD,然后分別以B、D為圓心,AB為半徑畫弧,得到兩弧的交點C,連接BC、CD,就得到了一個四邊形,猜一猜,這是什么四邊形?請你畫一畫。通過探究,得到: 的四邊形是菱形。證明上述結論:三、例題鞏固課本6頁例2 四、課堂檢測1、下列判別錯誤的是( )A.對角線互相垂直,平分的四邊形是菱形. B、對角線互相垂直的平行四邊形是菱形C.有一條對角線平分一組對角的四邊形是菱形. D.鄰邊相等的平行四邊形是菱形.2、下列條件中,可以判定一個四邊形是菱形的是( )A.兩條對角線相等 B.兩條對角線互相垂直C.兩條對角線相等且垂直 D.兩條對角線互相垂直平分3、要判斷一個四邊形是菱形,可以首先判斷它是一個平行四邊形,然后再判定這個四邊形的一組__________或兩條對角線__________.4、已知:如圖 ABCD的對角線AC的垂直平分線與邊AD、BC分別交于E、F求證:四邊形AFCE是菱形

請寫出 推理過程:∵ ,在兩邊同時加上1得, + = + .兩邊分別通分得: 思考:請仿照上面的方法,證明“如果 ,那么 ”.(3) 等比性質:猜想 ( ),與 相等嗎?能 否證明你的猜想?(引導學生從上述實例中找出證明方法)等比性質:如果 ( ),那么 = .思考:等比性質中,為什么要 這個條件?三、 鞏固練習:1.在相同時刻的物高與影長成比例,如果一建筑在地面上影長為50米,高為1.5米的測竿的影長為2.5米 ,那么,該建筑的高是多少米?2.若 則 3.若 ,則 四、 本課小結:1.比例的基本性質:a:b=c:d ;2. 合比性質:如果 ,那么 ;3. 等比性質:如果 ( ),五、 布置作業(yè):課本習題4.2

2.已知:如圖 ,在△ABC中,∠C=90°, CD為中線,延長CD到點E,使得 DE=CD.連結AE,BE,則四邊形ACBE為矩形嗎?說明理由。答案:四邊形ACBE是矩形.因為CD是Rt△ACB斜邊上的中線,所以DA=DC=DB,又因為DE=CD,所以DA=DC=DB=DE,所以四邊形ABCD是矩形(對角線相等且互相平分的四邊形是矩形)。四、課堂檢測:1.下列說法正確的是( )A.有一組對角是直角的四邊形一定是矩形 B.有一組鄰角是直角的四邊形一定是矩形C.對角線互相平分的四邊形是矩形 D.對角互補的平行四邊形是矩形2. 矩形各角平分線圍成的四邊形是( )A.平行四邊形 B.矩形 C.菱形 D.正方形3. 下列判定矩形的說法是否正確(1)有一個角是直角的四邊形是矩形 ( )(2)四個角都是直角的四邊形是矩形 ( )(3)四個角都相等的四邊形是矩形 ( ) (4)對角線相等的四邊形是矩形 ( )(5)對角線相等且互相垂直的四邊形是矩形 ( )(6)對角線相等且互相平分的四邊形是矩形 ( )4. 在四邊形ABCD中,AB=DC,AD=BC.請再添加一個條件,使四邊形ABCD是矩形.你添加的條件是 .(寫出一種即可)
