1. Preparation (1) Chant:教师播放三年级下册六单元A部分Let’s do的录音“Tall, tall, tall, make yourself tall…”师生一起吟唱并做出相应的动作。 (2) Free talk: T:Good morning/afternoon! Boys and girls. Ss: Good morning! Miss/ Mr… T: How are you? Ss: I’m fine. Thank you! And you? T: I’m fine, too. Who is your … teacher? Ss: Mr/ Miss… T: What’s he/she like? Ss: He/ She is …and … 引导学生描述自己的老师,复习学过的形容词。并适时板书这些形容词:tall, short, strong, thin, young, old. 设计意图:热身复习,通过一个形式活泼的chant复习与本课内容相关的形容词,创设英语氛围,激发学习兴趣,温故知新,为新课学习做铺垫。 2. Presentation (1)出示一张刘翔的图片,问:Who is he? What’s he like? 引导学生回答:He is Liu Xiang. He is tall. T: Yes, Liu Xiang is tall. (出示姚明的图片。)Look at Yao Ming. What’s he like? Ss: He is tall, too. T: Yes, he is tall. He is taller than Liu Xiang.(在tall后面用红笔加上er. 领读、拼读单词并说句子。) Make a chant: taller , taller, taller, Yao Ming is taller than Liu Xiang. T:Yao Ming is taller than Liu Xiang. Liu Xiang is shorter than Yao Ming. (在short后面用红笔加上er. 领读、拼读单词并说句子。) Make a chant: shorter, shorter, shorter, Liu Xiang is shorter than Yao Ming. 教师出示测量身高的米尺并说:“I am 158 cm tall. How tall are you?”引导学生测量自己的身高并用句子回答:“I am … cm tall.” 板书:cm=centimeter 领读、拼读单词并告诉学生它的复数形式: centimeters. 如:I am 158 cm tall. 读作:I am one hundred and fifty-eight centimeters tall. Ask and answer one by one. A: How tall are you? B: I am … cm tall. And you? A: I am … cm. I am taller/ shorter than you. (2)在一组学生问答练习结束时,教师接着说:“You are taller than me. But I am stronger than you.”在原来的板书strong后面用红色笔加上er.领读并拼读单词。 Make a chant: stronger, stronger, stronger, I am stronger than you. T:大家想知道老师为什么长得这么健壮吗?因为我坚持正确的饮食方法和锻炼身体。只要你们能够坚持正确的饮食方法和锻炼,也一定能有一个好身体。Look! I am stronger than you. You are thinner than me. 在原来的板书thin后面用红色笔加上ner.领读并拼读单词。告诉学生像thin这样的单词,在变为比较级时,要双写最后一个字母再加er. Make a chant: thinner, thinner, thinner, you are thinner than me. T: 教师出示测量体重的健康称,测量自己的体重说并:I am 52 kg heavy. How heavy are you?”引导学生用“I am … kg heavy.”回答问题。 板书:kg=kilogram 领读,拼读单词并练习说句子。让学生理解在实际句子中应该使用复数形式。如:I am 52 kg heavy.应读作:“I am fifty-two kilograms heavy.” Ask and answer one by one. A: How heavy are you? B: I am … kg heavy. And you? A: I am … cm. I am stronger/ thinner than you. (3)教师指一学生问:How old are you? S1: I am 12/… years old. T: I am 35 years old. I am older than you. You are younger than me. 在黑板上原来的板书old, young 后面加上er. 领读,拼读单词并练习说句子。 Make a chant: older, older, older. I am older than you. Younger, younger, younger, you are younger than your brother. Ask and answer one by one. A: How old are you? B: I am … years old. And you? A: I am … years old. I am older/younger than you. 设计意图:利用大家都非常熟悉的名人刘翔和姚明引入新单词taller和shorter的学习,形象直观,便于学生接受。而在学习stronger和thinner的时候,则直接用教师和学生的实际体重做为教学资源,让学生在实际生活中学习新知识。同时教育学生注意正确的饮食和锻炼,树立正确的健康观。Chant是小学生学习英语时最喜欢的练习方式,在学习新知时,用chant 加深学生的印象,便他们牢固掌握新学单词。 (4) Listen to the tape. Listen to the tape and repeat. (5) Read after teacher/ little teachers/ in groups. 设计意图:只有听得准才能模仿得准,说得好。所以听录音模仿语音、语调是学习英语中非常重要的一步。合作学习,小组互助既有利于学生合作精神的养成,也有助于每个学生都更好得掌握读音。 3.Practice (1) Read the new words in groups. (2) Spell the words. (3) Make the sentences with the new words. (4) Listen and do: Line up from older to younger. Line up from taller to shorter. Line up from thinner to stronger. (要求在站队的过程中只能用英语交流,看哪个小组站的最快,用中文提示的小组将被淘汰。) (5) Make a chant: taller , taller, taller, Yao Ming is taller than Liu Xiang. shorter, shorter, shorter, Liu Xiang is shorter than Yao Ming. stronger, stronger, stronger, I am stronger than you. thinner, thinner, thinner, you are thinner than me. older, older, older. I am older than you. Younger, younger, younger, you are younger than your brother. 设计意图:从读熟到拼写,只是一个机械操练的简单模仿过程,如何让学生在模仿的基础上达到熟练运用?本环节利用教材中pair work资源,让学生在听听做做中熟练掌握所学知识。这一环节的设计,不仅是一个听力活动,实际上是一个听说结合的综合活动,因为学生在听到教师的指令后,必须有一个交流的过程,而在这个过程中,教师要求他们必须用英语进行交流获得信息,这就更进一步地练习了所学知识。用一个形式活泼的chant,巩固所学新知,为下面的拓展作好了铺垫。 4. Production (1) Make a new chant like this by yourself. (2)在小组内调查同伴的身高、体重、年龄,并以获得的数据做一个对话。如: A: How tall are you? B: I am 152 cm tall. What about you? A: I am 153 cm tall. I am taller than you. B: Yes, I am shorter than you. How heavy are you? A: I am 48 kg. And you? B: I am 50 kg. You are thinner than me. A: Yes, I am stronger than you. How old are you? B: I am 12 years old. How about you? A: I am 11 years old. I am one year younger than you. B: Yes, I am one year older than you. 设计意图:学习英语的最终目的是为了达到学以致用,把语言知识转化为语言技能。在本环节的拓展应用中,我设计了利用自身数据做对话的活动。这个活动把要邢课所学的关于个人信息的三个方面综合在一起,编成一个综合性的对话,如果这部分掌握较好的话,为下面的对话学习将打下良好的基础。 5.Progress (1) 看板书,总结形容词比较级的变化规则。 根据规则做练习,写出下列形容词的比较级形式: small-- long-- big-- cool— high-- kind-- tall-- young-- (2) 做基础训练中本部分的相关练习。 Homework (1) 回家测量自己和父母的身高、体重。利用获得的数据做一个对话,和父母练习。 (2) 尝试用“I am … than..”来描述自己。 设计意图:形容词的比较级变化规则是本节课学习的重点,所以在课堂将近结束的时候,把这一变化规则再重新认识一次,让学生加深印象,并紧接着做一些练习进行巩固,让学生真正掌握这一知识技能。做活动手册练习是为了检测学生对本节课内容的掌握情况,以达到当堂达标。 板书设计 Unit 1 How Tall Are You? Part A Let’s learn tall—taller How tall are you? short—shorter I am … strong—stronger How heavy are you? thin—thinner I am … old—older How old are you? young—younger I am … cm=centimeter kg=kilogram I am taller/…than you.
