Unit6 SectionA 1a-2c课件2025-2026学年人教版（2012）九年级英语全册

该初中英语课件聚焦一般过去时的被动语态，以中国古代四大发明（如蔡伦造纸术、毕昇印刷术）为导入情境，通过“Look and say”呈现主动句到被动句的转换，再延伸至现代发明（电话、汽车等）的时间、发明者及用途讨论，搭建从已知到未知的学习支架。 其亮点在于融合文化意识与语言能力，借助听力匹配（1b发明与年份配对）、对话练习（2c询问发明用途）、小组汇报（Groupwork分享 favorite invention）等任务型活动，提升学生用被动语态表达的语言能力。结合“年份读法”细节教学，增强语言准确性，同时通过中外发明对比厚植家国情怀，学生在真实语境中运用语言，教师可依托结构化活动高效开展教学。
