Unit 2 Wildlife Protection Discovering Useful Structures 课件-2025-2026学年高中英语人教版必修第二册

该高中英语课件聚焦B2 Unit2“现在进行时的被动语态”，通过复习一般现在时与被动语态，自然过渡到新结构“be being done”，构建清晰的知识支架。从图片导入引发兴趣，逐步引导学生观察、归纳、操练，最终在真实语境中运用语言描述濒危动物保护措施，实现从理解到输出的完整学习闭环。 其亮点在于融合语言能力、文化意识与思维品质三大核心素养，以真实情境任务驱动学习。例如第6题“Many interesting experiments are being done these days”引导学生关注科学进展，培养批判性思维；第7题“Wild animals are in danger because habitats are being destroyed”唤起环保意识，强化人类命运共同体观念。教师可借此提升课堂互动质量，学生则能在语境中掌握语法结构，发展跨文化沟通与问题解决能力。
