S1: Who’s my favourite teacher? She’s young and tall. She’s strict but kind. S2: She’s our English teacher. 4. Read the words: tall, strong, old, young, short 意图：Free tall 的过程中复习了学过的句型和形容词，有助于 下一环节的开展。 Step 2 Presentation. 1. Show two pictures: Yao Ming and Liu Xiang. Ask and answer: Name Yao Ming Name Liu Xiang Age 32 Age 29 Height (身高) 229 cm Height (身高) 189 cm 意图：给出熟悉的体育明星 Yao Ming 和 Liu Xiang 的相片和信息， 一下子吸引了学生的眼球，学生会迫不及待的去了解和比较他们。 (1) older & younger . T: How old is Yao Ming? S1: He’s 32 years old. T: How is Liu Xiang? S2: He’s 29. T: Who’s older, Yao Ming or Liu Xiang? Ss: Yao Ming is older. Teach to read “older” —“er” /ə/ T: Who’s younger? Yao Ming or Liu Xiang? Ss: Liu Xiang is younger. Teach to read “younger” T：I’m 27 years old. How old are you? S1: I’m 13. T: I’m older than you. You are younger than me. 意图：学生们都掌握了如何询问对方年龄的句型，所以学生很 快能说出两位体育运动员的年龄，此时，教师再引导学生们对他 们的年龄进行比较，这样学生能容易地理解比较级的意义。同时， 把 older 和 younger 这对相反的形容词比较级放在一起教，能让 学生对它们的意思理解得更深刻，更有话说，运用得更到位。 (2)taller & shorter T: Yao Ming is 229 cm tall. How tall is Liu Xiang? Ss: He is 189 cm tall. Teach to read “cm ---Centimeter. cen-ti-me-ter”. Let Ss guess my height. Then let Ss introduce their height. T: Who is taller, Yao Ming or Liu Xiang? Ss: Yao Ming is taller. Teach to read “taller”. Then let Ss compare their height. e.g.: S1: I’m 155 cm tall. How tall are you? S2: I’m 155 cm tall. S1: I’m taller than you. T: Who’s shorter? Yao Ming or Liu Xiang? Ss: Liu Xiang is shorter. T: Yes. Liu Xiang is shorter than Yao Ming. Teach to read “shorter”. 根据前面几个形容词来引导学生初步 认识比较级后缀“er” 发音规律。 T: I have a brother. He is taller than me.
