人教版PEP六年级下册英语Unit4 第四课时 教案
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四单元第四课时。围绕“Mike和John的的变化”这一话题展开,主要通过对话学会用句型Before, I /she /he was. Now, I/she/he am/is.表达自己和他人过去和现在的情况,引导学生学会倾听,提高阅读能力。持续培养学生学习的兴趣,激发学生学习英语的热情,树立学好英语的信心。本课时是第三课时内容的延续和拓展,第三课时已经学习了如何表达自己对季节和喜好的变化,为本课时打下了很好的基础,所以本课时内容的理解,对于学生来说就很容易。本课时的的重点是重点句型的恰当运用以及能够运用35句话描述自己和他人的性格、爱好、外貌等方面的变化。本课时包括Lets try 和Lets talk两个板块。Lets try呈现了Mike 和陈杰讨论旧照片的情景,通过听力活动获得Lets talk板块的人物及场景信息。Lets talk 板块呈现了关于Mike的两幅图,一幅是Mike以前上课很安静,一幅是Mike现在上课活跃。两幅图的对比帮助学生理解Mike 性格的变化。此板块呈现的对话情境是陈杰和John正在参观 Mike的家,陈杰、Mike和John三个小朋友一起在看Mike的老照片。通过他们一起在看老照片的情景,谈论自己的变化。此情景的设计,贴近学生的实际生活,能够引起学生的共鸣,更能激发学生想要用英语表达的愿望,激起学生的求知欲。本课时是新授课,没有生词,句型简单,内容很容易被理解。但是语言的综合运用对于学生来说稍有难度。教师要采用歌曲、游戏、写话等多种活动形式,调动全体学生的积极参与,培养学生的语言综合运用能力。课时目标(1)学生能够理解对话大意,并能正确朗读所学对话。(2)能够在图片的帮助下,在情景中恰当运用句型Before, I /she /he was.
