Unit2 Topic3 SectionD课件 -2025-2026学年仁爱科普版（2012）九年级英语上册

该初中英语课件围绕“家庭环保行动”主题，涵盖新词汇（remove, replace等）、并列句（and/but/or/while等）及森林重要性等核心知识，通过Pre-reading图片情境（如男孩搬石头学remove/replace）和Warm up问题“假如世界没有森林”导入，结合Sections A-C填空练习复习旧知，搭建词汇-语法-阅读的学习支架。 其亮点在于情境化词汇教学（图片辅助理解remove...from...等短语）、分层阅读任务（Fast reading抓主旨、careful reading析细节）及主题写作（环保倡议书），体现语言能力（词汇语法运用）、思维品质（探究“无森林后果”）与文化意识（中国志愿者全球植树，增强家国情怀）。采用任务型教学，学生在学中提升语言运用与环保意识，教师可借助清晰结构与多样活动提高教学效率。
