I like monkeys. Theyre cute. Do you like animals? What animals do you like? Do you want to go to the zoo and watch animals there?OK! Lets have a race. Id like to divide you into three groups, the Tiger group , the Elephant group and the Bear group. If you do well, you can go up once. If you can get to the top, you are the winner, you can go to the zoo and have a good time there. （设计意图：通过唱歌让学生感知课文话题；通过说说自己喜爱的动物方式激发兴趣、活跃思维，以爬梯子比赛方式评价学生学习过程，调动学生情绪、给学生创造了一个轻松而又紧张的学习氛围。）Step 2. Presentation1. Sharp eyes 学生看课件读消失的单词，复习部分形容词；2. Lets say 教师引导学生看图描述动物特征Look at the giraffe/. Its so tall/.3.教师描述某一动物的特征，学生根据描述猜动物Guess: What is it? Its not big or fat. Its grey and black. Its very cute. It often says Meow. Yes, its a cat. (设计意图：通过Sharp eyes和Lets say活动，由词到句，引导学生复习如何描述动物的特征；用“猜一猜”活动激发学生的兴趣，将学生的思维方式拓展开来，复习相关词汇、句型同时，为新课的学习做好了铺垫。）4.出示猫图片，师生描述猫鼻子特征Look at the nose. Its small Its.引导学生说 a small nose,教读词组a small nose；呈现句型It has .教学句子 It has a small nose. 出示猪图片,对比教学 Look at the pig. It has a big nose.板书It has a nose.5.出示猴子和狗图片,教学 a long/short tail, It has a long/ short tail. 板书It has a tail.6. 出示熊猫和熊图片，教学big/small eyes, It has big/small eyes. 板书It has eyes.7. 出示狗和熊图片，教学big/small ears, It has big/small ears. 板书It has ears. (设计意图：通过看图，引导学生用新句型It has描述动物特征；描述身体部位特征时，教师先做好示范，然后学生模仿描述，学生描述的特征与教师所给示例相反，引导学生用恰当的形容词去灵活表达身体部位特征。训练句型时，教师引导学生先描述单数身体部位，然后过渡到复数形式，学习内容由易到难；对比模仿说句子，减轻了学生理解难度，同时可以帮助学生科学有效地记忆句型“It has a +形容词+单数身体名词”“It has +形容词+复数身体名词”。)8.课件出示大象图片Oh! Whats that? Its so big. Yes, its an elephant. 引导学生听句子Look at the elephant.学生跟读句子Look at the elephant.强调the在elephant前的发音/ i:/。引导学生描述大象：It has a long nose. It has a short tail.（设计意图： the在元音开头的单词elephant前读/ i:/ ,学生初次接触，教师做好发音示范，为学生正确朗读句子、课文做好铺垫。）9.教师做手势引导三、四位学生到讲台前Come here, children. Look at the elephant carefully .Tell me what it looks like, OK?播放大象喷水视频，学生仔细观察，然后依次描述大象的模样。教师请学生回到座位上：Well done, children. Please come back to your seats.教学children, Come here, children. (设计意图：通过邀请学生到讲台前看大象视频方式，巧妙设置情景，让学生理解Come here, children.含义，教学难点句子同时，引导学生继续描述大象的特征。)10.教师陈述Miss White and her students are watching an elephant, too. What does the elephant look like? Please watch the flash and find out.播放课文对话，学生听音找答案。Step 3 Practice1.学生听音，跟读对话两遍；师生分角色朗读一遍。2.学生打开课本P27，四人一组，分角色朗读并表演对话。部分小组表演对话。（设计意图：以角色扮演的形式引导学生熟读课文，学习并掌握新句型It has .通过表演，学生在语境中再次理解并巩固了难点句子Come here, children.的含义及发音）。3.教师设计情景：好朋友小明非常喜欢画画，今天她画的老虎不见了，请同学们听对话，根据她的描述，帮忙找出正确的那只老虎图片。4.教师拿出自己的玩具猴，Look here, children! I have a monkey. 师生一起描述It has a big head. It has a small nose. It has a big mouth. It has small eyes and big ears. Its cute. I like it. Do you like it?引导学生说Yes, I do.（设计意图：通过听音找图片及看实物描述动物特征方式，学生多途径地感知了如何整体描述动物特征的方法，语言输入方式灵活多样，为接下来描述动物特征做好了铺垫。）5. 师生示范T: What do you have, xxx? S: I have a .Look at the . It has a.
