Unit 4 Topic 1 When was it invented Section C(教学课件）-2025-2026学年仁爱科普版（2012）九年级英语上册

该初中英语课件围绕“发明创造”主题，涵盖重点单词（invention, crayon等）、短语（laugh at等）及一般过去时被动语态，通过Pre-reading小组讨论（如“什么是发明”）、Listening主旨题等环节，构建“讨论-听力-阅读-实践”学习支架，帮助学生掌握发明主题的语言运用。 其亮点在于任务驱动的探究式学习，如“讨论最重要/不重要发明”（如电脑、药vs糖果）培养思维品质（分析与评价），写作任务（描述自己的发明）提升语言能力（表达与篇章组织），结合flash、幻灯片等多模态资源调动参与。学生在实践中提升综合语言运用能力，教师可借助结构化活动设计提高教学效率。
