八年级英语上册Unit7ComicstripandWelcometotheunit教学设计（牛津译林版）。

8AUnit7Seasons教学设计

第一课时ComicstripandWelcometotheunit

一、教学分析

教学内容8AUnit7SeasonsComicstripWelcometotheunit（第80~81页），通过两只小狗Eddie和Hobo的对话，引出季节的话题。

教材分析ComicstripWelcometotheunit板块通过卡通漫画导入本单元的话题“season”，它是以非常逗笑的方式引出了季节的话题。在这一课时中不仅要求学生掌握相关的描写天气的重要词汇，还应让学生掌握两个重要句式：“Ibetyou’lllookcoolandfeelcoolwithnothingon!”和“Whichseasondoyoulikebest?”

学情分析学生在小学阶段已经对四季的描述进行过初探，本节课最大的特点是贴近学生的生活，容易激发学生的学习兴趣，但由于词汇及句子结构的局限性，需要教师开展各项活动引导学生学会如何用英语表达对四季的喜好态度。

教学项目词汇：rainy,snowy,bet

词组：lookcool,withnothingon

句型：Whichseasondoyoulikebest?

第五课时Integratedskills

一、教学分析

教学内容Integratedskills（第87～88页）

教材分析Intergratedskills部分主要通过出示图片、播放录音让学生学习一些描述天气的词汇。本课时重点为听、说技能的训练，要求学生能用一些功能用语谈论季节。

学情分析本单元的话题是四季，通过前面几个课时的学习学生对四季的表达及特点已经较为熟知，在读、写能力上有了很大提升，但在听、说方面教师们还需要用多种途径帮助学生加强练习，从而使得学生听说读写能力全面发展。

教学项目词汇:cloud,cough,kick,awful,fever,snowstorm,wind,around,rest,degree,bit,blow,loud,ring
