Unit 1 课时3 Section A Grammar Focus 课件 2026-2027学年人教版英语九年级上册

该初中英语课件聚焦一般过去时、现在完成时及used to结构，通过“Work in pairs”任务导入，引导学生圈画动词并区分过去动作、习惯与现在结果，借助对比表格和时间线构建时态知识支架，帮助学生建立前后语法点的逻辑联系。 其亮点在于融合语言能力与思维品质培养，通过贵州交通变化语篇（如“过去泥路难行，现在高速桥梁建成”）和情境对话（新图书馆交流），让学生在真实语境中辨析时态差异，同时设置句型转换、背默练习等分层任务。这不仅提升学生时态运用的准确性，还培养其用英语描述变化的能力，为教师提供系统的语法教学与实践素材。
