Unit 7 What's the highest mountain in the world？ SectionA 1a-2c 课时教学设计
课型 听说课 课时 1
教材分析
本课话题为谈论自然地理之最。活动1a的主题图呈现了四幅世界地理之最的图从而引出该部分的重点——“自然地理之最”的相关数据，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结的含义和用法；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，并用着四个地方的相关信息进行控制性的语言操练。2a和2c部分的听力资料则是让学生进一步利用比较级和最高级结构叙述“中国之最”的基本情况。
学情分析
学生在初一已经学会朗读百以内的数字，如何在此基础上朗读更大的数字是本课的一个重难点。对于要表达自然地理之最使用的比较级和最高级，学生在初二上学期也已有两个单元的学习，本课需在已有基础上，熟练掌握as...as.../one of+最高级/a little/lot/much+比较级等用法，所以在教学中应为学生创设情景，让其最大限度地使用以上句型来表达。
课时教学目标
语言能力：掌握词汇：square, meter, deep, desert, population, Asia, Qomolangma, the Nile, the Caspian Sea, the Sahara, the Yangtze River, the Yellow River等；掌握大数的读法。 学习能力：通过听说训练，学习并掌握物体长宽高及面积的表达。能够熟练运用形容词和副词的比较级、最高级。 思维品质：了解中国及世界地理和自然。 文化意识：通过比较，了解国家及世界“地理之最”，培养对祖国的自豪感，对大自然的热爱之情。
教学重难点
教学重点：掌握大数字的读法和表示度量的结构； 教学难点： 准确听取大数字和级别信息，正确表达度量结构；学会用不同句式表达比较级、最高级。
