U1 Section A (Grammar Focus)-【木牍中考】2026-2027学年九年级上册英语同步教学优质课件（人教版·新教材）

该初中英语课件聚焦九年级上册Unit 1语法，核心知识点为used to+动词原形、一般过去时与现在完成时的用法及区别。课堂导入通过歌曲《Used to Be Young》歌词中的used to自然引出过去与现在的对比，再结合例句对比三种时态，引导学生圈划动词并归纳标志词，搭建从观察到归纳的学习支架。 其亮点在于语法教学与“变化”主题深度融合，如4c短文以贵州交通发展为例，帮助学生形成对家乡发展的辩证认知，培育文化意识与家国情怀。通过“观察归纳-对话短文填空-写家乡变化短文及海报”的活动链，提升语言应用能力与思维品质，多样化练习及语言点辨析助力巩固。教师可直接使用结构化教学流程，学生能在实践中提升语法运用与跨文化沟通能力。
