2学情分析九年级的学生在经过了初中三年的英语学习，已经掌握了一定的基础，也具备了一定的听说读写能力。

在此之前也学过一些有关环境的词汇，且本单元属于九年级最后阶段的总复习单元，在课文中陆续呈现之前的语法知识如现在完成时，被动语态，情态动词的用法等。

但是目前的学生在学习英语的过程中所真正欠缺的是将英语作为一门语言真正运用于生活中。

另外还有一部分学生在课堂上不够积极，对英语不感兴趣，还需要教师精心的设计学生感兴趣的教学活动。

3重点难点1. 教学重点：（1）能正确运用现在进行时，现在完成时，被动语态，情态动词和used to 句型。

（2）保护环境的措施方法。

2.教学难点：能正确运用现在进行时，现在完成时，被动语态，情态动词和used to 句型。
