Unit 5 第5课时 Section B (2a-3c)-【木牍中考·名师教案】2026-2027学年九年级上册英语（人教版·新教材）

该初中英语教学设计聚焦发明主题的词汇变形、短语运用及语篇读写，通过复习蔡伦造纸的被动语态表达导入，衔接便利贴发明话题，搭建从词性转换（如invent→invention→inventor）到语篇填空再到写作的学习支架。 以真实发明故事（便利贴、飞机）激发兴趣，通过词性转换练习、图表梳理关键信息等活动，培养语言能力（准确运用词汇及被动语态）和思维品质（分析问题与解决问题），提供写作句型支架助力表达，提升学生综合语言运用能力，为教师提供清晰教学流程与反思方向。
