Unit 3 Grammar 教学设计-2022-2023学年高中英语上外版选择性必修第三册

《高中英语（上外版）》选择性必修第三册 Unit 3 Exploring the Unknown 课时：第 3课时 教学内容：Appositive clauses 课型： Grammar 一、教学设计与说明 1. 教学目标 本课为本单元的第三课时，核心目标为引导学生在探索未知的主题语境中理解同位语 从句的形式、功能与用法，比较同位语从句和定语从句的区别，在表达中正确使用同位语 从句。 2. 设计思路 本课为本单元的第三课时，学生已经通过前两个课时的学习对主题内容有所了解。本 课时旨在帮助学生在主题语境下理解并运用本单元的语法内容——同位语从句。本课先用 英国苏格兰北部的尼斯湖水怪作为导入，让学生在段落中体会同位语以及同位语从句的性 质。接着，学生结合图片以及所给词组的提示，将关于尼斯湖水怪的信息组合成完整的同 位语从句，再让学生自己从这些例句中观察总结同位语从句的特点，即：先行词通常为抽 象名词；从句的结构完整，遵循陈述句语序。之后，学生通过将两句简单句合并为复杂句 的练习，进一步感知同位语从句形成的过程，师生共同总结出同位语从句中可使用的若干 引导词。接着，再次回到 Reading A中 Stonehenge的故事，学生需在由课文改编而来的段 落中寻找同位语从句，同时从功能、先行词、句子结构三个方面来比较同位语从句和定语 从句，并且明确其区别。最后，学生以角色扮演的形式，运用同位语从句来介绍 Stonehenge，在探索未知的语境中，进一步巩固对同位语从句的理解和运用。 3. 重点难点 理解同位语从句的形式与用法，区分同位语从句和定语从句的特点，恰当运用同位语 从句进行表达。 1 Lesson Plan By the end of this period, students will be able to: 1. understand the form and the function of appositive clauses in the context of exploring the unknown; 2. identify the differences between appositive clauses and relative clauses through comparison; 3. introduce Stonehenge by using appositive clauses properly.
