说课
本节课的新授内容比较轻松、简单。在Sng time环节中，教师呈现了一首简单有趣的歌曲，歌词讲述了一对鸟儿原本栖息在小山上，后来因为环境污染，双双飞走了，它们都很迫切地希望能重返家园。教师通过做手势的方式拍摄了一小段手影戏，增加了趣味性，也帮助学生理解和学习歌曲。随后要求学生在原歌词的基础上创编歌曲，培养学生的能力同时也了激发学生的学习兴趣。
在Sund time环节中，教师呈现了陈述句的降调读法和一般疑问句句末升降调的读法。教师除了鼓励学生反复朗读，在听、读、模仿中感受英语的语调以外，还通过表格的对比、例子的引导等帮助学生感知并理解升调和降调。但教师要注意的是英美人在现实的日常交流中，一般疑问句的句末升调并不明显，甚至弱化到平调。因此，在平时的教学中不必追求刻意的升调，语调自然即可。本课的教学中，让学生掌握一般规则即可。
由于本节课的内容不多，难度不深，教师在本课的结尾处，还设计了一个巩固操练的环节。教师通过PPT课件呈现给学生一组环保画，学生通过欣赏和讨论，感受人类的破坏活动给地球带来的危害，让学生明白保护环境的重要性。学生在讨论中复习了本单元的一些主要句型，教师在语言上适当加以拓宽，在训练学生的语言表达能力的同时也引出了下个单元的话题：保护地球。
本节课的几个主要关注点：
关注学生在语言表达时使用正确的语调
关注学生语言表达能力的培养
关注学生的情感发展，树立他们的环境保护意识，帮助他们形成良好的卫生习惯使用范围和表达含义
