《高中英语（上外版）》必修第二册 Unit 1 Nature课时：第 3 课时课题：Relative clauses1— introduced by who, whom, that, which and whose课型：Grammar 一、教学设计与说明教学目标本课为本单元的第 3 课时，核心目标为引导学生掌握英语中由 who, whom, that, which 和 whose 引导的定语从句，指导学生在语篇中识别和理解这类从句，并根据语境恰当使用这类从句。设计思路本课通过主阅读的问答，导入语法，引导学生观察、识别和归纳“who, whom,that, which 和 whose 引导的定语从句”的形式、功能和意义。接着，依托教材 Moth poo 的语篇信息，选填恰当的关系代词。之后，基于板块话题，教师创设小明猪岛旅游的情境。旅游前，学生通过选句成篇，阅读小明推荐的猪岛介绍，并通过语篇改写，更加清楚地描述小明获悉的旅游攻略；最后，通过翻译练习，协助小明分享实时游记。通过教材和语境，学生能够识别和理解目标语法，并且能够学会在具体情境中正确使用定语从句。课后作业为教材练习和描述印象深刻的旅游经历。由于语法板块 ExerciseⅡ 是单句改写，阐述人与自然的关系，与本课所创设的情境联系不密切，因此本课将该部分内容布置为课后书面作业，帮助学生查漏补缺，巩固知识。此外，语段写作通过联系自身，介绍游记，有助于学生知识的迁移。重点难点通过回顾故事，识别和理解 who, whom, that, which 和 whose 引导的定语从句的形式、功能和意义；在具体情境中正确使用定语从句。Lesson PlanBy the end of this period, students will be able to:Identify the form, meaning and function of relative clauses introduced by who, whom, that, which and whose by reviewing the story;Use relative clauses properly in specific situations.Procedures:I.
