集体备课  一、单元教材分析

本单元围绕“识别物品的所属”，使学生学会询问物品的主人的基本句型“Is this/that your/her/his pencil? Yes, it is. No, it isn’t.; Are these/those your/her/his pens? Yes, they are. No, they aren't.”，体会一般疑问句的用法；由形容词性物主代词的用法，到初步学习名词性物主代词的用法；学习如何写“失物招领、寻物启事”，巩固所学单词的拼写“How do you spell pen? P-E-N.”。通过本单元的教学，使学生学会辨认物品的所有者，学会根据场景询问物品的所属，以及英语中对应的表达法，学会写寻物启事和失物招领。教师应着力培养学生能在日常交际交往中有效地使用语言进行表达，与他人沟通信息，为今后学习打下坚实的语言基础。本单元与第二单元衔接紧密，由this，that的学习过渡到these, those的学习，由指示一个人、物过渡到指示多个人、物，使学生学会区分远近单复数。

二、单元学情分析

本单元的主题是识别物品的所属，同时引导学生采用实物演示、课件模拟、小组合作学习和Role playing的学习策略，学习新词汇，掌握重点句型，使学生能比较好地解决类似问题（失物招领、寻物启事），既能提高学生解决问题的能力，又能巩固所学知识。该部分学习内容贴近学生的生活，谈论的主题是学生最关心的问题，极易于激发学生的主动性和学习兴趣。培养学生拾金不昧的精神和助人为乐、团结友爱的品德。

三、单元教学建议
