第四课时课时内容B Lets try Lets talk课时分析本课时是人教版六年级下册第一单元第四课时，与第三课时紧密相连。围绕“穿多大号的鞋”这一话题展开，主要通过对话学习句型What size are your shoes? I wear size .shoes./ Size.My shoes are size.及巩固句型How heavy are you? Im. kilograms.的表达。让学生了解中西方鞋子尺码的不同，培养学生学习英语的兴趣以及树立学好英语的信心。第三课时中已经学习了How heavy are you? Im. kilograms.的表达，为本课时奠定了基础。I wear 的句型四年级也已经学过，学生对于穿多大号的鞋的回答很容易掌握。所以本课时的重点是帮助学生理解和运用询问对方穿多大号的鞋及它的几种回答的表达。本课时包括Lets try和Lets talk两个板块。Lets try通过聊天呈现了Lets talk 的背景。学生通过听力练习获得Lets talk板块的人物和场景信息，为进入Lets talk的学习做好了准备。Lets talk 板块通过吴一凡和Mike 在鞋店试穿鞋子的情景，让学生感知What size are your shoes? Size.How heavy are you? Im. kilograms.的语义和语用情景，学会如何在这样的情景下表达。此情境是发生在鞋店里，与学生的生活息息相关，很能激起学生的求知欲。本课题涉及了前面几个课时的内容，在设计本课教学过程时，我采用游戏、问答的方法，帮助学生巩固学过的知识。学习对话时采用整体感知对话、局部处理语言、模仿对话、表演对话的方法，充分发挥学生的主体作用。课时目标1. 能够理解对话大意。2. 能够用正确的语音、语调朗读对话，并能进行角色扮演。3. 能够听、说、读、写句型：What size are your shoes?
