过程 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。) 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. 板书设计
