Unit1 The changing world SectionA Grammar focus课件2026-2027学年人教版英语九年级上册

该初中英语课件围绕“The Changing World”主题，聚焦简单过去时、used to及现在完成时三大核心时态，通过“周围变化”提问导入，先复习过去时，再讲used to（过去习惯与现在对比），最后现在完成时（对现在影响），构建时间逻辑学习支架。 其亮点在于结合贵州交通变化等生活情境设计对话与短文填空，通过表格对比时态结构和用法，提升思维品质。“Think deeply”环节联系社会发展，渗透文化意识，增强家国情怀，助力语言能力提升，对学生巩固时态用法、教师系统教学均有帮助。
