Unit6 When was it invented？ SectionA 1a～1c课件 2025-2026学年人教版（2012）九年级英语全册

该初中英语课件围绕“一般过去时被动语态”核心知识点，聚焦谈论发明的历史与用途。课堂导入从复习年份读法切入，通过中国古代四大发明（如造纸术）与现代新四大发明（高铁、网购等）的对比，结合猜谜游戏、句子匹配（纠正发明与发明者时间错误）及小组讨论发明顺序（如电话与电视先后），搭建从已知到新知的学习支架。 其亮点在于融合中外发明文化（古代四大发明与现代新四大发明，外国发明如电话、汽车），培育文化意识；通过小组讨论发明顺序、猜谜问答提升思维品质（分析比较），句型转换等练习强化语言能力。采用任务型活动与情境创设，总结明确句型与年份读法，助力学生在文化对比中提升语言运用，教师可直接用于互动教学，提高效率。
