This is my book. 这是我的书。（2）名词性物主代词起名词的作用。例：Look at the two rulers. The red one is yours. The blue one is mine.看那两把尺子。红的是你的，蓝的是我的。3. 形容词性物主代词、名词性物主代词的区别简单来说，有“名”则形“，无“名”则“名”。意思是：后面是名词的话，前面就要用形容词性物主代词。后面没有名词的话，就用名词性物主代词。名词性物主代词=形容词性物主代词+名词 例：Are these your crayons? =Are these yours? 第一课时一、课时内容 Read aloud Listen and tick二、课时分析本课时是人教版四年级下册Recycle 2单元第一课时。围绕“野餐、购物”的话题展开，主要通过对话和听力复习46单元句型，引导学生养成节约的好习惯，培养学生学习英语的兴趣，树立学好英语的信心。第一课时是对46单元句子的归纳，重点是46单元核心句型的灵活运用。 本课时包括Read aloud和Listen and tick 两个板块。Read aloud呈现的是Sarah 、张鹏和Amy一起去农场野餐的情景。此情境有趣、易懂，贴近学生的生活，很能激发学生学习的兴趣。Listen and tick 板块呈现的是四组听力判断题，通过这个活动复习有关购物的语言。 本课时是复习课，词汇、句子学生都在前面的教材中学过了，有了很好的基础，所以在本课教学中，重点以学生为主，教师为辅，通过采用听、说、读、演等多种活动全面调动学生的积极参与，让学生在快乐的氛围中掌握知识。三、课时目标（1）能够听、说、认读46单元的核心句型：Are they/these/those?Yes, they are.
