第五课时一、课时内容B Lets talk B Lets act二、课时分析本课时是人教版四年级下册第六单元第五课时，与第四课时紧密相连。围绕“商品的价格和印象”这一话题展开，主要通过对话学习词汇how much, eighty, dollar，句型How do you like.? How much is.? Its.及巩固描述商品品质的句型Its very.。引导学生理性消费，激发学生学习英语的热情以及树立学好英语的信心。第三课时中已经学习了Its very.的表达，为本课时做了很好的铺垫。所以本课时的重点是理解词汇how much, eighty, dollar和询问对于某商品的印象以及询问并回答商品价格的表达。本课时包括Lets talk和Lets act两个版块。Lets talk 版块通过Sarah和妈妈继续购物的情景，让学生感知How do you like.? How much is.? Its.的语义和语用情景，学会如何在这样的情景下表达。此情境是发生在服饰里，与学生的实际生活相关，更能激起学生想要学习和表达的欲望。Lets act版块呈现了许多的衣服，学生选三件适合寒冷天气穿着的衣物，总价不得超过50元，在小组内模拟购物。情节设计有趣，锻炼了学生的语言运用能力。本课时涉及了前面的内容，在设计本课教学时，我采用游戏、儿歌的方法，帮助学生巩固学过的知识。采用局部处理语言、呈现完整对话、模仿对话的方法学习对话，采用猜价格、模拟购物等活动操练对话，充分发挥学生的主体地位。三、课时目标1. 能够在语境中理解词汇how much, eighty, dollar2. 能够理解对话大意。3. 能够用正确的语音、语调朗读对话。4. 能够听、说、认读、运用句型：How do you like this skirt?
