Unit7 Whats the highest mountain in the world?Section A (1a-2c)教学设计 海南澄迈思源实验学校 王 娜1、 教材分析本课选自义务教育教科书2013人民教育出版社出版八年级下Unit7 Whats the highest mountain in the world?Section A 本部分内容主要围绕地理知识展开，集中呈现了大数字的读法和表示度量的结构，进一步拓展了比较级和最高级的使用。1a-1c为本单元的导入部分。活动1a的主题图呈现Qomolangma,The Nile, the Caspian Sea和Sahara四副图，从而引出改部分的重点“自然地理之最”的相关数据。1a部分重点突出如何用含有大数字的度量结构表达这些地理信息。活动1b的听力材料呈现了描述这四个地方的比较级和最高级结构，学生通过听后填空来熟悉这些结构的含义和用法。活动1c让学生结对操练，通过模仿听力中大数字的读法，口头再说出这些大数字，并用这四个地方的相关信息进行控制性的语言操练。2a-2c部分的重点是听和说的教学。借助我国人口、历史的话题内容，将学生带入我们自己的地理与人文语境中。听力活动按梯度设计，要求学生能够通过听获取地理知识中的一些重要数据及与之相关的文化信息。知识目标：根据课程标准和本课的内容及其教材所处的地位，结合初中学生的实际情况，我制定以下教学目标：在完成本节课的学习任务后,学生能够:1) 正确识记和拼读以下单词:meter n.米,deep adj.深的, desert n.沙漠,population n.人口,Asia n.亚洲2. 正确认知和理解形容词比较级、最高级的不同表达方式如higher than any other mountain3.能正确表达较大数字的读法以及“数词+名词复数+形容词”结构的用法技能目标：1.学生能根据图片提示，运用用形容词的比较级和最高级谈论地理及自然方面的知识；2.能根据已有知识猜测听力材料，提高听力水平情感目标：通过谈论地理和自然方面的知识，开阔学生的视野，并形成保护自然和环境的意识教学重点、难点：1学会谈论世界地理和自然。2. 熟练掌握形容词和副词的比较级和最高级。教学方法：视听说教学方法、情景教学法教具：Overhead Project，PowerPoint 【教学过程】一Warming up ： 1.观看英文歌曲where are we going ,Dad?2.
