1、Unit 2 Yes or No 教案（第一课时）教学目标：1. 能听懂、会说、会读单词 computer, radio, camera。2. 能运用is this /that ？进行提问并回答： yes，it is. / no, it isnt.3. 能理解感叹句 what a nice! 对物品进行赞美。4. 能正确地使用礼貌用语may i come in? come in，please.教学重点： 让学生在实际情境中结合学过的物品单词，运用is this /that a? 进行问答。 教学难点：is this /that ?句型初次出现，this与that的读法及用法比较混淆，应设计直观
2、的情景和多样的操练，让学生从感知到理解并走向运用。另外，新授单词正确发音也是一难点。教学准备：教师: 多媒体课件、歌曲、课文磁带、电话机、电脑、照相机、收音机、单词卡片、人物头饰。学生: 准备一些精美的物品，包括衣服、文具等。教学过程：step 1 warm up1t: (站在教室门口) may i come in? 引导学生说 come in, please. (if you say yes, you can say come in, please.)2. greeting. sing a song. abc song.3. t: boys and girls. you look nice
3、today. let me take a photo for you. (take out a camera) look, its my new camera. its nice, isnt it?新授单词 camera, 并引导学生用what a nice camera!来赞美。大组齐喊 camera! (开摄)，教师将照相机对准那一大组拍摄，并宣布下课后给表现最好的学生拍一张集体照。（把重要单词放在小小的热身中，降低学习难度，激发学生学习热情。）step 2 presentation1. 教师走出教室，拿出nancy手偶，敲门，大声说：may i come in?（反复几次）ss: com
4、e in, please.（简单直观的方法，让学生在亲身运用语言的过程中体验语言的交际功能。）2. 教师假装带着nancy参观教室, what a nice classroom! n: whats this/ that (on the )?ss: its a desk/ chair/ door/ window/ book .教师随手指着或拿起学生的一些文具用品。n: is this/that a/ your ? (is this/ that ? 重读并注意上升语调。)t: yes, it is. / no, it isnt. （示范清晰）引导学生回答。学生可以用 yes. 或 no. 做简单回
5、答。教师发出赞叹 what a nice ! （教师带小客人nancy参观教室，就教室中的物品随机发问，引导学生观察教室，自然直观，有助于学生理解问题含义并做简单回答。）3. t: now, youre nancy. try to answer my questions together.t: (walk to a tv) is this a tv?ss: yes, it is. 教师指导发音，由慢到快，配上表示正确的动作或拍手。t: (point to a computer) is this a tv?ss: no, it isnt. 教师指导发音，配上表示否定的动作（两手胸前交*）和yes
