Im cm tall. Youre er than me. How heavy are you? Im kg. Im thinner than you, and shorter.”3、能朗读故事。三、教学重难点1、教学重点：书写及运用本单元重点单词和句子。2、教学难点：理解及运用形容词比较级。四、教学准备：课件，单词卡，作业纸，自制尺子（组评）五、教学过程：Step1 Warm-up1. Free talkHello! /Hi! /Good morning! /Nice to meet you! /Whats your name? /How old are you?(本节课是借班上课，授课教师与学生之间存在一定的信息差。上课伊始，通过谈论拉近师生之间的距离，并自然渗透How old are you ? Im older than you. Youre younger than me.)2. Enjoy a song “ Alibabas Farm”T: Alibaba he has a little farm. On his farm, he has two pigs. One is Shooby. One is Dooby.Step2 Review1 Play a game “Shooby Dooby”如果老师说Shooby Dooby，tall.学生就要taller,taller,taller，并作出相应的动作。2、Shooby Dooby考考你！课件呈现比较词汇的变化规律：a、直接加er; b、尾字母是e的直接加r; c、双写尾字母加er; d、y改成i再加er。（采用演绎法，让学生说出更多的词。在此环节渗透smarter一词）3、Say the opposite words根据黑板上的词卡，进行反义词配对。4、Review the sentences从上一环节最后一词taller, 自然引出身高的问答。T: Im 162 cm tall. How tall are you? 把本节课的重点句型板书并进行师生问答。再从师生实际情况的问答到课件上的姚明、周杰伦的身高比较，板书比较句型。 / 根据课件图片进行体重比较到师生间的比较 Im 49 kg. How heavy are you? （板书重点句型，结合课件操练）5、Pair work 根据语言支架进行同桌操练6、T：How long are your rulers?（指黑板上的组评四把尺子）画出三把不同长度的尺子比较。Ruler 1 is longer than Ruler 2, but shorter than Ruler 3. 在这个基础上画出了一个大圆和一个小圆，来让学生操练bigger和smaller。为丰富操练机会在大圆内画出了一个比大圆小，比小圆大的圆来让学生操练，最后还在小圆中画出了一个最小的圆。从而使学生的语言得到了充分的操练。在这一步之后给黑板上的球和尺添了几笔就变出了一个天平，让学生操练Ball 1 and Ball 3 are heavier than Ball 2 and Ball 4。Step3 Presentation & PracticeShooby & Dooby1、 Listen & writeShoobyHeight(身高)：_cmWeight（体重）：_ kgTail(尾巴)：_cmDoobyHeight(身高)：_cmWeight（体重）：_ kgTail(尾巴)：_cm做完听力，根据图片和表格Say something about Shooby and Dooby, using the sentence “ is _er than ”。2、呈现story（1） Fill in the blanksAli baba he has a little farm.
