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. Don’t break the school rules.(板書,教讀)步驟3 :Practicea. T: Now, each of the students is breaking one of these rules.Please finish 1a.學生看圖,完成1a的內容,檢查答案并大聲朗讀校規(guī)。b. 聽錄音,完成1b,選出四位學生都違反了哪條校規(guī);聽之前,學生要讀會英文名。c. 請兩位學生朗讀1c部分的句型;要求學生兩人一組對話表演,SA扮演外校轉來新生,SB告知本校校規(guī)。(學生可經(jīng)過討論,多說出他們想到的校規(guī),不必只限于書上;教師應給予幫助)2) 第二課時(2a~4)步驟1 :warming up of revisionT: What are the rules at your school?學生使用“can”或祈使句表達各條校規(guī);其中老師可引出“eat in the cafeteria outside”的表達。步驟2 :Practicea.T: Christina is an exchange student. She doesn’t know the rules. Let’s listen, what activities they’re talking about?學生聽第一遍時,完成2a;第二遍時,完成2b;b. 請學生領讀2c部分,看著2a完成的表格,理解2c活動的要求;分成小組針對2a進行問答;

三、教學建議第一課時:1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places. For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4. Homework 1.2.

1 Each group choose one place to describe and what you are doing in it Choose one place, and describe what they are doing 2 Move around the room and give suggestions Talk about it and write it down 3 Ask one to show their works and act it Choose one of each group to make a report 4 Evaluate the best group and the best reporter Choose the best one Homework Ask your friends their ideal place and write about it教學反思:新課程標準中強調學生在課堂中的主體地位,在綜合課中他們的主體地位就更加突出。在各個活動中給不同程度的學生不同層次的任務,讓各層面的學生都有表現(xiàn)發(fā)揮的機會,從而產生對英語的興趣。使用照片圖片多媒體來輔助教學,效果更好。同時讓了解其他國家風景,風俗的同學介紹ideal place,增加學生的背景知知識,實現(xiàn)跨學科交流的目的。教案點評:采用任務型教學模式,在各個活動中給不同程度的學生不同層次的任務,讓各層面的學生都有表現(xiàn)發(fā)揮的機會,從而產生對英語的興趣。使用照片圖片多媒體來輔助教學,效果更好。讓了解其他國家風景,風俗的同學介紹ideal place,增加學生的背景知識,實現(xiàn)跨學科交流的目的。

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)。

說明:在幫Li Lei提建議的同時,教育學生如何學好英語。第三課時教學目標1. 語言目標:a) 詞匯: Original, in style, haircut, the same as.b) 語言結構:My friend wears the same clothes and has the same haircut as I do.2. 能力目標:大多數(shù)學生能夠談論自己喜歡哪種服裝,提高查找信息的能力。3. 情感目標:學會如何與朋友相處,要有自己對時尚的看法。教學重點掌握一些重要詞匯。教學難點學會談論問題,并能提出書面建議。◆教學突破首先針對Erin的問題,提出個人的建議,模仿2c部分的對話展開雙人交際Pair-work;聽老師誦讀3a部分的信件,并找出LEFT OUT的問題所在;學生完成3b部分的內容,給Left Out提出書面的建議;學以口頭形式提出自己目前存在的某個問題,講給大家聽,讓同學們給自己提出一個建議,并作筆錄;學生兩、三個人分成一組,隨意性地進行口語交際,談論P14的第4部分的某個問題,相互交換意見。

"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。)

區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句,都叫做主從復合句。賓語從句主要是中考必考的,是初中階段必掌握的從句,賓語從句主要是掌握三要素,所謂賓語從句,就是賓語在主從復合句當中充當賓語的一個句子,叫做賓語從句。主句的謂語動詞是及物動詞,后面如果是詞或者是短語的話,是簡單句,如果是句子的話,肯定是賓語從句。I know that he good at English.就是賓語從句,三要素,一要素是要注意連詞,連詞一共學了三類連詞,一類連詞是that口語當中可以省略,就像剛才說的那一句,I hear he is good at English.還有疑問代詞、疑問副詞,how where when,疑問代詞、疑問副詞。還有一類連詞weather是否的意思,不是狀語從句當中的如果,這一定要和如果區(qū)分開,這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序,要用陳述舉語序。比如說你家有幾口人,我們都說How many people are there in you family?但是這是簡單句,一旦說成賓語從句,你可以告訴我你家有幾口人嗎?Could you tell me how many people there are in you family ?

Step Ⅱ Show the new words on the screen and teach the new words. Read the new words to students and ask them to repeat.Step Ⅲ 3aThis activity introduces new vocabulary and provides reading practice using the target language.In this activity first look at the four pictures.T: What can you see in the pictures?Ss: Four snow globes.T: Right. There are four snow globes in the pictures. And what are they?Ss: They are a monster, two polar bears, two penguins and a birthday cake.Write these words on the blackboard: snow globe; monster; polar bear; penguin and birthday cake. Read them to the class and ask students to repeat each one. Make sure students understand each word.Use a computer to show the E-mail message on the screen and read the message to students.Get students to read the e-mail on their own, and then draw lines connecting each snow globe and its description.Correct the answers.AnswersA line should connect each snow globe picture with the words that describe it in the letter.Step Ⅳ 3bThis activity provides writing practice using the target language.First review Activity 2a on Page 47.Then ask students to complete the message according to Activity 2a.Some partial sentences are given to students. Write about one person's collection.When students work, walk around the room checking the progress and offering help as needed.When they finish, ask some students to read their messages to the class.

(一).知識方面: 1.培養(yǎng)學生能運用過去進行時來描述、談論過去某個時間正在發(fā)生的事情或動作的意識和能力,能就過去某個時間正在發(fā)生的動作做出正確的描述。 2.培養(yǎng)學生的想象力和角色扮演的合作能力。 3.培養(yǎng)學生講述過去發(fā)生的事情經(jīng)過的能力。能正確運用一般過去時來講述故事。 (二).技能方面: 1.本單元的語言目標是Talk about past events and tell a story(談論過去的時間和講述一個故事),圍繞這一目標,要涉及句型: What were you doing when the UFO arrived? ----I was sitting in the barber’s chair. The barber was cutting my hair. 因此必須學習standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地點的詞,以便為上述句型提供語言材料。2.學習過去進行時的有關知識。Was/were+現(xiàn)在分詞,是該時態(tài)的表達式。 3.在學習過程中,要區(qū)分The boy was walking down the street when the UFO landed.和While the boy was walking down the street, the UFO landed.這兩種由when和while引導的狀語從句的句型結構。注意它們的不同。

教學不應僅僅傳授課本上的知識內容,而應該在傳授知識內容的同時,注意對學生綜合能力的培養(yǎng).在本節(jié)課中,教師并沒有直接將運算法則告訴學生,而是由學生利用已有知識探究得到.在探究過程中,學生的數(shù)學思想得到了進一步的拓展,學生的綜合能力得到了進一步的提高.當然一節(jié)課的提高并不顯著,但只要堅持這種方式方法,最終會有一個美好的結果.2.充分挖掘知識內涵,使學生體會數(shù)學知識間的密切聯(lián)系在教學中,有意識、有計劃的設計教學活動,引導學生體會單項式乘法與單項式除法之間的聯(lián)系與區(qū)別,感受數(shù)學的整體性,不斷豐富學生的解題策略,提高解決問題的能力.3.課堂上應當把更多的時間留給學生在課堂教學中應當把更多時間交給學生.本節(jié)課中計算法則的探究,例題的講解,習題的完成,知識的總結盡可能的全部由學生完成,教師所起的作用是點撥,評價和指導.這樣做,可以更好的體現(xiàn)以學生為中心的教學思想,能更好的提高學生的綜合能力.

通過以上例題幫助學生總結出分式乘除法的運算步驟(當分式的分子與分母都是單項式時和當分式的分子、分母中有多項式兩種情況)4、隨堂練習。(約5分鐘)76頁第一題,共3個小題。教學效果:在總結出分式乘除法的運算步驟后,大部分學生能很好的掌握,但是還有些學生忘記運算結果要化成最簡形式,老師要及時提醒學生。 分解因式的知識沒掌握好,將會影響到分式的運算,所以有的學生有必要復習和鞏固一下分解因式的知識。5、數(shù)學理解(約5分鐘)教材77頁的數(shù)學理解,學生很容易出現(xiàn)像小明那樣的錯誤。但是也很容易找出錯誤的原因。補充例3 計算(xy-x2)÷ ? 教學效果:鞏固分式乘除法法則,掌握分式乘除法混合運算的方法。提醒學生,負號要提到分式前面去。6、課堂小結(約3分鐘)先學生分組小結,在全班交流,最后老師總結。

情景感知概括運用設疑誘導動手操作合作交流嘗試活動啟發(fā)引導類比發(fā)現(xiàn)演練結合觀察分析自主探索問題討論利用嘗試活動“我來當老師!”給學生提供設計問題的機會,培養(yǎng)他們實事求是的科學態(tài)度,勇于質疑、敢于創(chuàng)新的良好習慣及數(shù)學應用能力。例1、根據(jù)因式分解的概念,判斷下列由左邊到右邊的變形,哪些是因式分解,哪些不是,為什么?通過羅列一些似是而非、容易產生錯誤的對象讓學生辨析,促使他們認識概念的本質、確定概念的外延,從而形成良好的認知結構。例2:解答下列問題:(1)993-99能被99整除嗎?能被98整除嗎?能被100整除嗎?(2)求代數(shù)式IR1+IR2+IR3的值,其中R1=19.2,R2=35.4,R3=32.4,I=2.5。讓學生進一步體會用分解因式解決相關問題的簡捷性。例3、填空:若x2+mx-n能分解成(x-2)(x-5),則m=,n=。

此題的設計目的:及時的練習一是起到鞏固新知識的目的,二是及時了解學生掌握新知識的情況,起到反饋的目的。這樣設計的依據(jù)是:小題多,是讓更多的學生參與到學習中來,及時給予他們更正,更多的是對他們的鼓勵和表揚,有簡單的題盡量讓基礎不太好的的學生去說,以讓他們感受到成功的樂趣;并且《新課標》中指出課程內容應處于學生“最近發(fā)展區(qū)”的范圍以內,讓成功始終伴隨學生學習的旅程,以保證學生不會因過多的失敗而放棄他們的努力,失去發(fā)展的機會。第四環(huán)節(jié):師生合作,歸納總結。先由學生個人總結,然后教師補充。設計目的:通過學生個人小結,教師可以了解學生掌握知識的情況,培養(yǎng)學生總結概括的能力,教師補充起到完善所學知識的目的。第五環(huán)節(jié):布置作業(yè),鞏固提高。設計目的:因材施“作業(yè)”,分層次布置作業(yè),減輕學生的負擔,全面推行素質教育,讓學生學有用的數(shù)學,不同的學生學習不同的數(shù)學,在數(shù)學中得到不同的發(fā)展,以求彰顯學生的個性。

一、說教材:等腰三角形是北師大版初中八年級下冊數(shù)學教材第一章第一節(jié)的教學內容,本節(jié)是軸對稱圖形的應用,是研究等腰三角形的開篇。通過本章節(jié)的學習,可以豐富和加深學生對已學圖形的認識,為以后的圖形學習和證明打好基礎。本節(jié)在編排上考慮學生的認知規(guī)律,從學生容易接受的動手操作找規(guī)律開始到幾何畫板的驗證再過渡到幾何證明與應用。根據(jù)課程標準,確定本節(jié)課的目標為:【教學目標】1.知識與能力 理解并掌握等腰三角形的定義,探索等腰三角形的性質;能夠用等腰三角形的知識解決相應的數(shù)學問題.2.過程與方法通過動手操作、動態(tài)演示等方法,培養(yǎng)學生思考探究數(shù)學的能力;通過例題與練習,提高學生添加輔助線解決問題的能力。3.情感、態(tài)度與價值觀 在探索等腰三角形性質的過程中體會軸對稱圖形的美,感受數(shù)學與生活的聯(lián)系;在例題教學中,感受數(shù)學之美;培養(yǎng)學生分析解決問題的能力,使學生養(yǎng)成良好的學習習慣.

1.通過實例體會一元一次不等式組是研究量與量之間關系的重要模型之一。2.了解一元一次不等式組及解集的概念。3.會利用數(shù)軸解較簡單的一元一次不等式組。4.培養(yǎng)學生分析、解決實際問題的能力。5.通過實際問題的解決,體會數(shù)學知識在生活中的應用,激發(fā)學生的學習興趣。能在解決問題過程中勤于思考、樂于探究,體驗解決問題策略的多樣性,體驗數(shù)學的價值。四、教學重、難點分析教學重點:1.理解有關不等式組的概念.2.會解由兩個一元一次不等式組成的不等式組.教學難點:在數(shù)軸上確定解集.五、教學手段分析本節(jié)課采用多媒體教學,利用多媒體教學信息容量大、操作簡單、形象生動、反饋及時等優(yōu)點,直觀地展示教學內容,這樣不但可以提高學習效率和質量,而且容易激發(fā)學生學習的興趣,調動積極性。

注意:平行四邊形中對邊是指無公共點的邊,對角是指不相鄰的角,鄰邊是指有公共端點的邊,鄰角是指有一條公共邊的兩個角.而三角形對邊是指一個角的對邊,對角是指一條邊的對角.(教學時要結合圖形,讓學生認識清楚)設計意圖:通過觀察圖片和回顧以前的知識,使學生由感性認識上升到理性認識。通過描述平行四邊形的特點和定義,也培養(yǎng)了學生的語言表達能力。同時也滲透了一些由實際問題轉化為數(shù)學問題的“轉化”的數(shù)學思想。(三)、引導實驗探索新知【探究】平行四邊形是一種特殊的四邊形,它除具有四邊形的性質和兩組對邊分別平行外,還有什么特殊的性質呢?我們一起來探究一下.動手操作并思考:讓學生根據(jù)平行四邊形的定義畫一個一個平行四邊形,觀察這個四邊形,它除具有四邊形的性質和兩組對邊分別平行外以,它的邊和角之間有什么關系?度量一下,是不是和你猜想的一致?

學生在觀察和討論后,由師生合作,歸納出中心對稱的性質:(1)關于中心對稱的兩個圖形,對稱點所連線段都經(jīng)過對稱中心,而且被對稱中心所平分;(2)關于中心對稱的兩個圖形是全等圖形.讓學生嘗試自己證明△ABC與△A′B′C′全等,然后在教師的引導下相互交流。接著,對“軸對稱”和“中心對稱”的概念進行比較,我采用列表格的方式,從三個方面分別讓學生去填,意圖讓學生把新學的知識及時納入到已學的知識體系中去。4、靈活運用體會內涵1)首先講授例1。(1)選擇點O為對稱中心,畫出點A關于點O的對稱點A′;(2)選擇點O為對稱中心,畫出線段AB關于點O的對稱線段A′B′.(3)已知四邊形ABCD和O點,畫出四邊形ABCD關于O點的對稱圖形。在老師的引導下,共同完成作圖,并規(guī)范畫圖方法:要畫一個多邊形關于已知點的對稱圖形,只要畫出這個多邊形的各個頂點關于已知點的對稱點,再順次連接各點即可。在本次活動中,意圖利用中心對稱的性質進行作圖,加強對中心對稱性質的理解。
