Unit 6 An old man tried to move the mountains. SectionA (2d&Grammar Focus-4c ) 课时教学设计
课型 听说+语法课 课时 1
教材分析
本课时的话题是谈论自然地理之最。通过观察、归纳、探究等活动，引导学生进行如何询问及表达具体事实的典型句型的语法学习，以及比较描述的句型、形容词比较级和最高级的用法和更加丰富的有关比较的表达方式。本课主要是一节语法课。2d材料为学生呈现了一个完整的关于明长城基本信息的对话范例，让学生体会所学语言在真实语境中的使用情况，并为学生模仿语言和进一步拓展该话题提供了示范。Grammar Focus以表格的形式罗列了如何询问及表达具体事实的典型句型，为学生操练提供了示范。活动4a通过形容词、副词的选择和变化巩固形容词在原级、比较级、最高级中的表达形式；4b是一个半控制性的语法练习，要求学生理解句意，把握同类事物进行比较的正确表达；4c是一个两人结对活动，让学生在互动的模式中根据真实情景运用比较级、最高级表达事物的比较。
学情分析
在前两个课时的基础上，学生对形容词、副词的比较级、最高级的不同句式用法及表意功能有了初步的感知，本课时通过归纳总结，帮学生较为系统地梳理法，语法现象的总结难度不大，但实际运用中灵活运用的难度较大，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。
