英语人教版四年级下册U2 B.lets talk.doc

Unit2 My schoolbag B Lets talk 一、学情分析: 学习本课前，学生已有一年多的英语学习经验，具有一定的语感，能自然感知不同句型的语音语调以及良好的学习习惯，学生保持积极的学习态度，建立了学习英语的自信心。已接触过颜色，学具，形状，数量等话题，能初步用英语进行简单日常交流的能力，表演欲望很强，善于观察、记忆、想象和创造。二、教材分析 本单元学习的主题是描述书包的颜色并说出书包里的课本及其它物品的名称,进而展开单词、TPR以及对话教学，主要掌握9个三会词语schoolbag/math book/English book/Chinese book/story book/notebook/candy/toy/key和主要句型I have a /Whats in?/What colour is it? /Its.以及Lets spell.中I字母的开音节发音规律。重点句型在教材中通过复现形式不断加深和巩固，语音课时可以放手让学生拼读，充分发挥学生的主体性，提供大量的课外词汇让学生学会摸索规律，体验成功的快乐。本课时教学内容为 B Lets talk/lets play，重点学习What colour is it?复习 Whats in it?让学生感知句型的语义和语用情景，难点是Excuse me./Here it is 的表达。三、整体设计思路 复习：颜色、书本、语音导入：失物招领情景1（小小失物招领角）操练：失物招领情景2（自助服务系统，迅速突破难点）课文文本输入（大量朗读活动）运用：失物招领情景3（捣蛋鬼游戏，活动面向全体，充分运用课本文本）强化重点句型（简易游戏）测标(稍微提高难度)四、教学目标1.知识目标：能在情境中恰当运用句型What colour is it? Its问答颜色，理解新词lost的意思和正确发音。2.能力目标 ：能理解对话大意；能用正确的语音、语调朗读对话；能用失物招领语境中常用句型完成简单的交际任务。3.情感目标：学会爱护文具物品，培养路不拾遗的品德，上交捡到的物品，进行爱心教育并赞美乐于分享的美德。五、教学过程：. Warming up activities. (自学)Activity 1. Show time. Read your word cards in pairs. What do you have? I have a schoolbag/maths book/English book/Chinese book/storybook etc.(设计意图:通过小对话检查学生的词汇书写和发音。)Activity 2. Lets sing. Colour song. Red and yellow and pink and green. Purple and orange and blue. I can sing a rainbow. Sing a rainbow. Sing a rainbow now. Remind them that “colour” and “color” are also correct.(设计意图:复习有关颜色的单词，为本课时描述物品颜色的环节做好预热,活跃课堂气氛。)Activity 3. Look and try. Give them 3 new words. Discuss in group of four. How to read the words? i-e /ai/ai/ai/wife, i-e/ai/ai/ai/time, i/i/i/i/dig(设计意图:通过上节课的语音知识，培养学生看词能读的能力). Presentation.（导学） Activity 1.Set a sceneLost & Found. 在教室角落挂上写着LOST AND FOUND字样的可爱指示牌（可用卡纸制作），两张桌子并列，上面放两个箱子，事先装好物品，如红领巾，带树皮的书本等等，设置像样的小小班级失物招领角落。Pretend looking for a bag. Where is my bag? I cant find/see it. Help! Is it under the ? No! What colour is it? It is red. (more students suggestions.) Oh, I lost my bag. (设计意图:通过情景导入，在询问和建议的帮助过程复习方位词，颜色及相关的旧句型。)练习：连线Where is my bag? Its red.What colour is it? Its under the desk.Activity 2. At the Lost & Found. 自助服务系统，按start键开始说话，按enter键确认。A: Excuse me. I lost my bag. B: What color is it? A: Its purple. .B: Here it is. A: Thank you so/very much. Hide something of the students. They can go to the Lost and Found.(设计意图:这个情景非常有趣，设计起来很简单，拉上一布帘，布帘前面左右贴上两个单词即可。类似银行自助柜员机和网上在线人工服务系统一样。先通过简短有趣的情景对话，让学生突破本课难点：Excuse me. I lost Here it is.这些句型，再教课文的文本，课文稍长些。)Activity 3.Text teaching1)Listen to the dialogue and answer : What colour is Mikes schoolbag? Whats in it? 2)Lets read together. 有感情地朗读，模仿正确的语音语调。3)Now boys be Mike. Girls be Miss White. 分角色朗读，注意语音语调。4)Then read in pairs.(设计意图:用足够的时间朗读，熟悉文段，整理对话的顺序,加深文本记忆。本课时的重点句型不难，What colour is it? Its blue and white. 学生很快能掌握，重要的是灵活运用句型。). Practice.（互学）Activity 1.Close your eyes for 10 seconds. Your 2 classmates will play a trick on you. What happened? Who lost a bag? Lets act.今天失物招领值日总动员，鼓励多找问题问失主，尽可能找到真正的物主。(设计意图:先请较优秀的学生表演，为其它学生树立信心，起到示范作用。面向全体的设计，利于更多学生开口。)Activity 2. Lets play.学生把准备好的单词卡拿出来玩游戏。玩之前，先利用P17的图，让学生看图说话。A:I have a new book. B: What colour is it? A: Its blue. B:I ts a book.(设计意图:在游戏中充分运用颜色词进行询问和复习了有关书本的词汇，相对上面的对话活动显得简单多了，可以为下一个稍微枯燥的阅读活动作一个缓冲。)练习：排序( ) An English book, two toys and a notebook.( )Excuse me, I lost my schoolbag.( )Here it is.( )What colour is it?( )Its blue and white.( )Thank you so much,( )OK.Whats in it?Activity 3. Lets checkP201) listen and number2) look and circle(设计意图:对所学知识进行检测).Consolidation. （测标）对话整理：A. Excuse me. B. Here it is. C.I lost my bag. D. What color is it? E. It is pink. F. Oh, this bag is old. Mine is new . （设计意图：优秀生特别喜欢有一点点的挑战，而对于非优秀生如果听懂了这节课，也能通过猜测做出来。）.Summary.（小结） 我们学习了失物招领对话中最常用的句型，要学会
