Unit1 The Changing World Section A 3a-3d（第 2 课时）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“家乡变化”主题，涵盖11个核心词汇（如interview, greenhouse）和现在完成时语法。通过“Past vs. Present”情境对比（土坯房与新楼层等）及话题讨论（交通、教育变化）导入，以词汇游戏、阅读策略（略读、寻读）和对话预测为支架，衔接词汇、阅读与语法学习。 其亮点在于融合语言能力、文化意识与思维品质培养。通过角色扮演（记者与村民对话）和小组讨论（家乡各方面变化）提升语言综合运用能力，融入社会主义新农村建设内容增强家国情怀，对比现在完成时与一般过去时（如“in the past 10 years”用完成时）培养逻辑思维。采用情境教学与合作学习，结构化小结帮助系统梳理，助力学生提升跨文化理解，教师可高效实施教学。
