Unit 6 Section A 1a-2d（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Unit 6 "When was it invented?"的被动语态（when/by whom引导的疑问句）及发明的时间、发明者、用途展开，从基础句子翻译入手，通过发明家介绍（爱迪生、墨翟等）、发明与发明者匹配、时间排序等环节，搭建从词汇积累到语法运用再到语用实践的学习支架。 其亮点在于融合听、说、读、写活动，如听力匹配发明与年份、Pair work角色互换问答、拉链对话角色扮演，提升语言能力。引入中外发明对比（中国风筝、西方电话等）增强文化意识，讨论小发明用途培养思维品质。学生在合作学习中综合运用语言，教师可通过结构化活动提高教学效率。
