Unit1第3课时(3a-3d)课件2026-2027学年人教版九年级英语上册

该初中英语课件围绕Unit 1 "The Changing World" Section A 3a-3d，核心聚焦词汇（词根词缀速记）和语法（used to与现在完成时）。课堂导入通过选择居住地A/B并描述原因，用已知设施词汇（如highways, housing）引入新词汇（如high-tech, greenhouse），搭建从生活情境到语言知识的学习支架。 其亮点在于采用词根词缀法提升学习能力（如high-tech=high+tech），对比过去现在变化培养思维品质（3a表格对比年轻人工作地点等），分层作业满足不同学习需求。含听力活动（3b听对话），小结明确核心语言点。帮助学生提升词汇记忆和语法运用，教师可高效实施差异化教学。
