Unit 1 Topic 3 Section C课件2025-2026学年仁爱版(2012)英语九年级上册

该初中英语课件围绕社会问题（无家可归、童工等），聚焦相关词汇（basic, whatever等）、阅读策略（找主题、主旨句）及“cause and effect”写作，通过视频导入（观察无家可归者）引发思考，Pre-reading铺垫词汇，While-reading以任务链（选标题、匹配主旨、填表）搭建阅读支架，Post-reading过渡到小组讨论与写作，形成输入输出闭环。 其亮点在于以任务驱动提升语言能力，如上下文猜词（Task-4）和细节提取（原因-影响表格）；通过“cause and effect”分析（写作框架）培养思维品质；关注社会问题渗透文化意识，如讨论无家可归者措施增强责任感。学生能提升语言运用与逻辑思维，教师可借助完整活动设计提高教学效率。
