Whos missing?教师每次出示三张单词卡片，让学生观察2秒钟，然后再快速出示其中两张，让学生抢答哪个单词失踪了？比比观察力和记忆力。3. Practise“How much is it?”(1)游戏：贵还是便宜？利用学生熟悉的“幸运52”的游戏方式，让学生猜测商品（衣服的实物或图片）的价钱，具体做法如下： 出示一件colourful dress，并事先预设好其价格为￥400，问学生：T:What that?Ss:Its a dress.T:How about that dress?/Is it colourful?Ss:Its colourful./Yes,it is.T:How much is that colourful dress?让学生来猜测其价格。当学生把价格说得低于400元时，教师就说：Its too cheap.反之就说：Its too expensive.以此来巩固新授单词。当学生最后说出了正确的价格（400元）后，教师亮出价格标签并说：Oh,its very expensive,very expensive!并让学生跟读。出示一条pretty skirt，并预设其价格为￥300，教师用以上方法让学生猜，再次巩固Very expensive,very expensive!出示第三件商品一件yellow shirt，预设价格为￥12，教师问：T:Whats this?Ss:Its a yellow shirt.T:How much is this yellow shirt?当学生猜到其价格后，肯定会大吃一惊，这时教师就说：Very cheap! Very cheap! (2)Lets chant教师将上述三件衣服的图片和相应的价格标签贴在黑板上，并出示游戏的结果，即出示Lets chant中的文字，然后播放磁带，让学生听、跟读、说唱。四、Consolidation小组合作：教师先进行示范表演，教师扮演售货员，学生扮演顾客，适当添加内容进行对话表演。如：A:How much is this sweater?B:Its 40 yuan.A:Its pretty/cheap/colourful.Ill take it./I want this lamp.B:OK.Here you are.A:Thank you.
