單元分析單元目標: Talk about what people are doing 單元主要句型:1.What are you doing ?I’m doing my homework .2.Do you want to go swimming ?Yes , I do .3.When do you want to go ?At three o’clock .4.What is he doing ?He is watching TV. 單元詞匯:watching , doing , eating , cleaning , playing , reading , swimming , shopping , pool ,school , mall , library , wait , talk to , talk about , activity , camero , bird 重點、難點:1.be動詞am , is , are的用法;be動詞前面我們已經(jīng)學(xué)過,這一單元主要是與分詞一起構(gòu)成現(xiàn)在進行時態(tài),即be (am , is , are)+V-ing,表示正在干什么。它主要是隨主語人稱的變化而選擇不同的。2..現(xiàn)在進行時態(tài)上面我們講be (am , is , are) 時已提及進行時態(tài),其句子的構(gòu)成情況我們通過下面的兩個表格中的問句、答句來具體體現(xiàn):3.現(xiàn)在分詞的構(gòu)成現(xiàn)在進行時態(tài)中be + V - ing 的構(gòu)成中V-ing被稱為現(xiàn)在分詞,它的基本構(gòu)成是動詞原形+ing,但也有些特殊情況,下面分幾類說明:(1)一般情況+ing如:read→reading,go→going,do→doing,look→looking,listen→listening,watch→watching.(2)以不發(fā)音的e結(jié)尾的詞,去掉e,再加ing.如:write→writing,skate→skating,type→typing,wake→waking,make→making
三、說教學(xué)重難點1.i、u、ü、y、w和yi、wu、yu的正確認讀;i、u、ü和yi、wu、yu的四聲練習(xí)。(重點)2.i、u、ü的第二聲和第三聲的正確發(fā)音;韻母、聲母和音節(jié)的初步區(qū)分;知道y和ü在一起組成音節(jié)ü上兩點要省略的拼寫規(guī)則。(難點)四、說教學(xué)過程(一)單韻母i、u、ü的教學(xué)1.讀準音。教師要充分利用情境圖引導(dǎo)學(xué)生說話,發(fā)現(xiàn)圖中字母的音、形等元素。可以先引導(dǎo)學(xué)生觀察情境圖,說說看到了誰,它們在干什么。結(jié)合學(xué)生說話時具體的語言情境,借助“衣、烏、魚”3個字的讀音引出單韻母i、u、ü。(1)發(fā)音指導(dǎo)。告訴學(xué)生i、u、ü和ɑ、o、e都是單韻母,發(fā)音時一樣,口型不能變動。通過反復(fù)示范,引導(dǎo)學(xué)生觀察i、u、ü發(fā)音時的嘴型,掌握發(fā)音方法。同時,還可以利用第一單元學(xué)過的漢字“一”和“五”來幫助正音,讓學(xué)生說說書上有哪些數(shù)量是“一、五”的景物,如一件衣服、一個男孩、一棵樹、一只烏鴉、一條小河、一條魚、一只烏龜;五個字母……將學(xué)習(xí)拼音與既有知識相結(jié)合,由舊知到新知,提高教學(xué)效率。

4.聯(lián)系作者的寫作背景賞析第三節(jié),說說第三節(jié)中的意象有怎樣的象征意義。通過這些意象,我們可以看出作者的思想感情有怎樣的變化?明確:意象:“神話的蛛網(wǎng)”“雪被下古蓮的胚芽”“掛著眼淚的笑渦”“雪白的起跑線”“緋紅的黎明”?!吧裨挼闹刖W(wǎng)”象征束縛生產(chǎn)力發(fā)展,鉗制思想解放的專制統(tǒng)治和陳腐意識,只有掙脫了“神話的蛛網(wǎng)”才能誕生“簇新的理想”;“雪被下古蓮的胚芽”“掛著眼淚的笑渦”“雪白的起跑線”“緋紅的黎明”這些意象在時空上大幅度跳躍,構(gòu)成了立體交叉象征義,象征著祖國成長的苦難歷程、再生的悲喜、新長征的開始和未來的美景。上述意象有一個共同的特征,那就是代表著希望,代表著開始。作者正是用這些意象,表現(xiàn)著自己的欣喜與激動。
教學(xué)聲母y、w應(yīng)與認識整體認讀音節(jié)yi、wu、yu結(jié)合起來,教師可以先借助情境圖及“衣、屋、烏、魚”的音幫助讀準它們的音。同時通過比較yiyi、wuwu和üyu,讓學(xué)生知道:y、i、yi都讀“衣”,w、u、wu都讀“屋”,ü和yu都讀“迂”。
二、學(xué)習(xí)新知1.正方形的定義在這一環(huán)節(jié)中,學(xué)生很容易犯的一個錯誤就是條件重復(fù)。這時我會引導(dǎo)學(xué)生從畫圖入手,提示他們:你能不能減少條件畫出正方形呢?這一環(huán)節(jié)中我的觀點是正方形的定義不是唯一的。我們可以從不同的角度來總結(jié),只要合理就加以肯定。比如當(dāng)學(xué)生總結(jié)出:四個角都是直角,四條邊都相等的四邊形是正方形。這時可以提醒學(xué)生是不是一定要四條邊都相等,減少邊的條數(shù)可以畫出來嗎?角的個數(shù)可以減少嗎?鼓勵學(xué)生動手試一試。通過動手畫圖可以很容易的得到正方形的一個定義:三個角都是直角,一組鄰邊都相等的四邊形是正方形。通過小組討論的形式來完成這一環(huán)節(jié)的設(shè)置。鼓勵學(xué)生利用現(xiàn)有的材料繼續(xù)構(gòu)造正方形。從另一個角度總結(jié)正方形的定義。
Step 3 (3b)First, tell the students when we talk about our future plans, we often use: I’m+verb+ing When we talk about what we must do, we use have to. Ask the students to fill in the blanks in 3b. The answers are: shopping, go to see, a test, I’m going, my family. Step 4 (3c)Let the students write an e-mail message to a friend. Say why you can’t visit next. Before the exercise, ask the students to give some possible answers and write them on the blackboard. So the students will feel easy to finish the writing exercise. After they finish it, Let them to correct it in groups first. Each group chooses theirs best one to read in front of the whole class. Step 5 ( planning a party )First read the conversation in the box together. Then ask the students to turn to page 88.Write down everything you have to do next week. Write in all the things you have to do . Ask the students to look at the list. Ask them “What day are you free?” This is when you can have your party. Step 6 (Self check 1 )Let the students to fill in the blanks with the words given. Change the forms of the words if possible. Then make their own sentences. The answers are: visit, playing, have to, study, comeStep 7 (Self check 2)Imagine you are Marie. Read the information and look at your schedule. Write replies to the invitation.
2、課標要求對于本節(jié)課內(nèi)容課標要求:探索并掌握兩個三角形全等的條件;注重所學(xué)內(nèi)容與現(xiàn)實生活的聯(lián)系,注重經(jīng)歷觀察、操作、推理、想像等探索過程。初步建立空間觀念,發(fā)展幾何直覺;在探索并掌握兩個三角形全等的條件,與他人合作交流的過程中,發(fā)展合情推理,進一步學(xué)習(xí)有條理的思考與表達。二、學(xué)生分析 1、七年級學(xué)生的理解能力和思維特征和生理特征,學(xué)生好動性,注意力易分散,愛發(fā)表見解,希望得到老師的表揚等特點,所以在教學(xué)中應(yīng)抓住學(xué)生這一生理心理特點,一方面要運用直觀生動的形象,激發(fā)學(xué)生的興趣,使他們的注意力始終集中在課堂上;另一方面要不斷創(chuàng)造條件和機會,讓學(xué)生發(fā)表見解,充分發(fā)揮學(xué)生學(xué)習(xí)的主動性,體現(xiàn)學(xué)生的主體地位。
一、教材分析1.教材的地位與作用本節(jié)課是在學(xué)生學(xué)習(xí)了三角形的基本概念后,引入圖形的全等。這節(jié)課探究對象是生活中的常見全等圖形,主要是探究全等圖形的概念和特征,通過系列學(xué)習(xí)活動,引導(dǎo)學(xué)生體驗數(shù)學(xué)與生活的密切聯(lián)系,激發(fā)學(xué)生學(xué)習(xí)數(shù)學(xué)的興趣,培養(yǎng)良好的學(xué)習(xí)品質(zhì)。同時這節(jié)課的內(nèi)容也是下一節(jié)學(xué)習(xí)全等三角以及三角形全等的判定的奠基石,它對知識的聯(lián)系起到承上啟下的作用。2.教學(xué)目標依據(jù)《課程標準》要求本階段的學(xué)生應(yīng)初步會運用數(shù)學(xué)的思維方式去觀察、分析現(xiàn)實生活中出現(xiàn)的實際問題,體會數(shù)學(xué)與生活的密切聯(lián)系,增進對數(shù)學(xué)的理解和學(xué)好數(shù)學(xué)的信心。因此我確立本節(jié)課的教學(xué)目標如下:知識技能目標:通過實例,使學(xué)生理解圖形全等的概念,掌握全等圖形的特征,能在不同的圖形中識別出全等的圖形過程與方法:通過觀察,動手實驗,培養(yǎng)學(xué)生動手操作能力、觀察能力以及合作與交流的能力

【學(xué)習(xí)目標】1.知識與技能:知道氧氣的制取及檢驗方法,復(fù)習(xí)鞏固氧氣的相關(guān)性質(zhì)。2.過程與方法:通過“探究能使帶火星木條復(fù)燃所需氧氣的最低體積分數(shù)”的探究性學(xué)習(xí),學(xué)習(xí)科學(xué)探究的基本方法。3.情感態(tài)度與價值觀:提高實驗設(shè)計的能力和合作意識,復(fù)習(xí)鞏固相關(guān)的基本操作,培養(yǎng)學(xué)習(xí)化學(xué)的興趣?!緦W(xué)習(xí)重點】氧氣的實驗室制取操作步驟和性質(zhì)檢驗?!緦W(xué)習(xí)難點】實驗操作過程中的注意事項?!菊n前準備】《精英新課堂》:預(yù)習(xí)學(xué)生用書的“早預(yù)習(xí)先起步”。《名師測控》:預(yù)習(xí)贈送的《提分寶典》。情景導(dǎo)入 生成問題1.復(fù)習(xí)引入:實驗室用高錳酸鉀制取氧氣的反應(yīng)原理是什么?操作步驟有哪些?2.明確學(xué)習(xí)目標,由學(xué)生對學(xué)習(xí)目標進行解讀。合作探究 生成能力閱讀課本P45~P46的內(nèi)容。提出問題:實驗室加熱高錳酸鉀制取氧氣的實驗中,使用了哪些儀器?哪部分是氣體發(fā)生裝置?哪部分是氣體收集裝置?為什么可用排水法收集氣體?討論交流:結(jié)合化學(xué)實驗基本操作和氧氣的性質(zhì)討論歸納。
“拱一拱手,一屁股就坐在上席”,兩個動作活畫出了夏總甲在鄉(xiāng)民面前的傲慢自大。作者接著寫他的一番話語:“俺如今倒不如你們務(wù)農(nóng)的快活了。想這新年大節(jié),老爺衙門里,三班六房,那一位不送帖子來。我怎好不去賀節(jié)?每日騎著這個驢,上縣下鄉(xiāng),跑得昏頭暈?zāi)X。”“從新年這七八日,何曾得一個閑?恨不得長出兩張嘴來,還吃不退?!鼻擅畹亟沂玖怂麨楹文恐袩o人和衣服“就如酒簍一般”。二、通過故事情節(jié)的前后對比來表達諷刺。第二回中,周進六十多歲了,還以老童生的身份在薛家集觀音庵教私塾,一年才十二兩館銀,生活窘困,地位低下,村中新中秀才青年梅玖也奚落他。到第七回中,周進中了進士,做了官以后,梅玖就無恥地冒充自己是周進的學(xué)生,薛家集的觀音庵里也供起了周進的長生牌位。梅玖見了周進早年寫的一副對聯(lián),貼在墻上,紅紙都發(fā)白了,竟吩咐和尚用水噴了,剝下來裝裱收藏。這一對比既寫出了周進做官前后迥然不同的境遇,也寫出了秀才梅玖的庸俗勢利以及社會上一些人的趨炎附勢。所以,《儒林外史》的諷刺,不僅僅是對人物的諷刺,更是對當(dāng)時社會中各種現(xiàn)象的揭露、控訴和批判。
說明:在幫Li Lei提建議的同時,教育學(xué)生如何學(xué)好英語。第三課時教學(xué)目標1. 語言目標:a) 詞匯: Original, in style, haircut, the same as.b) 語言結(jié)構(gòu):My friend wears the same clothes and has the same haircut as I do.2. 能力目標:大多數(shù)學(xué)生能夠談?wù)撟约合矚g哪種服裝,提高查找信息的能力。3. 情感目標:學(xué)會如何與朋友相處,要有自己對時尚的看法。教學(xué)重點掌握一些重要詞匯。教學(xué)難點學(xué)會談?wù)搯栴},并能提出書面建議?!艚虒W(xué)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(xué)生完成3b部分的內(nèi)容,給Left Out提出書面的建議;學(xué)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(xué)們給自己提出一個建議,并作筆錄;學(xué)生兩、三個人分成一組,隨意性地進行口語交際,談?wù)揚14的第4部分的某個問題,相互交換意見。
1 交通工具的比較此活動為小組活動。學(xué)生通過討論找出到達某一城市可乘坐的各種交通工具,并選擇最佳出行方式。Teacher:We’re going to Shanghai. How many ways can we use to get there? Yes, there are four ways: by bus, by plane, by train, by ship.

It’s more comfortable and cheaper than any other transportation.We can go there by bus. It’s cheaper but it takes longer time.2 哪個城市更合適?此活動具有挑戰(zhàn)性。假設(shè)中國要舉行2014年世界杯足球賽,分別從歷史,人文,天氣等方面對各城市(北京,大連,上海,昆明)進行比較,選擇最佳舉辦城市。T: Imagine China is holding the 2014 FIFA World Cup.

教學(xué)說明:問題(1)是借助“邊邊邊”條件判定三角形全等的知識來解釋的。因為三邊長度確定后三角形的形狀就被固定了,因此三角形具有穩(wěn)定性。問題(2)可用多媒體展示三角形穩(wěn)定性在實際生活中應(yīng)用的例子。要解決問題(3),只需要在四邊形中構(gòu)建出三角形結(jié)構(gòu),這樣就可以幫助其穩(wěn)定。設(shè)計意圖:通過學(xué)生動手操作,探究三角形穩(wěn)定性及生活中的應(yīng)用,讓學(xué)生體驗數(shù)學(xué)來源于生活,服務(wù)于生活的辯證思想,感受數(shù)學(xué)美。 (五)總結(jié)反思,情意發(fā)展問題:通過這節(jié)課的學(xué)習(xí)你有什么收獲?多媒體演示:(1)知識方面:①三邊對應(yīng)相等的兩個三角形全等,簡寫為“邊邊邊”或“SSS”。②三角形具有穩(wěn)定性。(2)技能方面:說明三角形全等時要注意公共邊的應(yīng)用。
(1)教師說:“Zhang Peng’s mother is a teacher.What does she teach? Does she teach English?”教師出示Let’s talk部分的掛圖,放錄音,學(xué)生聽錄音閱讀對話。教師出示主句型:Does he/she…?Yes,he/she does.No,he/she doesn’t.然后教師引導(dǎo)學(xué)生回答剛剛提出的問題,逐步掌握肯定和否定回答。再放一遍, 學(xué)生跟讀. (2)教師說:“My mother is a teacher,too.Do you want to know more about her.Ask me some questions.”教師依次出示B Let’s learn部分的單詞卡片,提示學(xué)生根據(jù)上面的短語和黑板上的重點句型提問,教師作答。 (3)教師指導(dǎo)學(xué)生進行替換練習(xí)。必要時,提示學(xué)生可以換一下對話里的人物,f 如:Does your uncle live in the city? Yes,he does.Does your grandma live in the country? No,she doesn’t. (4)“尋找家園”游戲 教師準備一些卡片,正面寫有人名,反面寫有地名,如:city,country,village,farm,forest,mountain,nature park等。請一名學(xué)生上臺抽取一張卡片,問臺一學(xué)生:“Guess.Where does…live?’’學(xué)生猜:“Does he/she live in/on…?”猜對的小組得一分。
