Unit13 We‘re trying to save the earth! SectionB 1a～1e课件 -2025-2026学年人教版（2012）英语九年级全一册

该初中英语课件围绕环保主题，核心知识点包括词汇recycle、napkin，句型Turn off... when...及It's hard to do sth.，聚焦听说能力培养。课堂导入通过Warming up引入环保话题，1a让学生给环保措施（如关灯、回收纸张）从易到难排序，激活认知后，1b与同伴用目标句型比较答案，搭建从词汇到听说的学习支架。 其特色在于融合语言能力与思维品质，通过分层听力练习（1c听大意、1d辨细节）提升信息获取能力，小组讨论“鲨鱼呼吁人类停止捕杀”培养批判思维与环保责任感。采用任务型教学（排序、对话、自测），学生在实践中强化语言运用并树立环保意识，教师可借助结构化活动与知识点总结高效实施教学。
