八年级上册英语 比较级用法 教案

这是一份八年级上册英语 比较级用法 教案，共4页。
比较级用法(一）教学内容分析本单元的核心话题是对人物的外表进行描绘，个性进行比较。本单元的语言结构是形容词，副词比较级用法，这一语言结构在初中阶段的学习是教难理解和掌握的，需要大量的语言操练才能实现。所以在第一课时设计了这样一堂听说语法课，在创设的具体情境中去掌握比较级的用法。本节课的话题与学生的日常生活息息相关，所以，学生们会比较感兴趣。本节课的学习，对学生英语表达能力和综合能力也有很大的帮助。有助于提高他们为应用而主动学习和掌握语言知识的兴趣。(二）教学目标知识目标形容词或副词比较级形式的构成。 表示两者进行比较的句式结构。技能目标1) 通过学习本课，学生能够用比较级句式表达。2) 提高学生的听说读写技能3) 鼓励学生实践、参与和合作活动情感目标 能在小组活动中积极与他人合作，相互帮助，共同完成学习任务。（三）教学重难点利用所学的目标语进行熟练交际。(四) 学情分析   学习本单元之前，学生已经学过许多表达喜好的方式。但是用定语从句来表达喜好，对于学生来说，有一定的难度。教师要通过各种不同的语境跟学生交流，或者给学生提供不同的语境让学生互相练习，使学生扎实地掌握并运用定语从句表达喜好。（五）教法任务教学法，编排了一系列听说读写综合语言活动，让学生学会用比较级进行表达，这些活动紧贴学生的生活实际，极具真实性，视听教学法，通过一些形象的图片，多媒体展示等方式，激发学生们的学习兴趣，从而使学生的个人经历成为课堂学习的有效图式，有助于学生对所获取的声音和文字英语信息的理解；有助于调动他们用英语表达自己的经验和感受兴趣和热情；有助于促进他们语言功能的运用（六）教具准备多媒体课件（七）教学过程Step 1 Warming-up : T：Where did you go on vacation?S: ...............T: I went to the Palace MuseumT: I went to the bird’s  nest .The Olympics was held in the bird’s nest.Do you know the spirits of Olympics?The spirits of Olympics: higher, faster and stronger.Do you notice the three words are all ended with “er”?
