论文部分内容阅读
教材分析：保護树木这个专题是我们英语初中阶段一个最常用而且很重要的专题，无论是阅读，听力，口头，还是写作都会涉及。学生在Unit Four Save the trees Reading里学习了很多关于描述树木重要性的句型和短语，由于BookB Listening PartB的内容与Reading联系更紧密，故选此节并修改作为听说材料。本节课通过Listening、speaking等活动，让学生巩固描述树木重要性的句型和短语，并激发学生如何爱惜树木的意识，培养学生绿色生活的态度，同时号召身边的人共同参与。
学情分析：本班学生英语成绩位于区平均线以下，但对英语学习有一定的热情；对本话题较为熟悉，对基本的句型也掌握得不错。但是在具体的听说运用时会有一定困难，尤其是关于“如何保护树木”的英文表达很欠缺。
