Unit 1 课时3 Lesson 3（课件）英语新教材冀教版八年级下册

该初中英语课件围绕“春城昆明”主题，核心讲解when和while引导的时间状语从句，结合昆明天气、景点的阅读材料展开。课堂通过“Watch and say!”视频观看导入，提问“Which city is it?”引出昆明及“春城”称号，搭建从城市认知到阅读分析再到语法学习的递进支架。 其亮点在于融合阅读与语法教学，以昆明相关文本为载体，通过分段概括段落大意（如天气、景点），结合实例拆分时间状语从句（如“When we talk about spring, we think of...”），培养学生语言能力与思维品质。Practice环节的对话补全、选择填空及拓展作业（用时间状语从句介绍所在城市）提升学习能力，助力学生语言运用，也为教师提供结构清晰、活动多样的教学方案。
