九年级英语Unit 13 Section B-Reading
Rethink , Reuse , Recycle !教学设计
一、教材分析：
本课是该单元的第四课时，主要内容是2a的阅读的学习，这一部分图文并茂，用了三个有同样前缀的词语Rethink , Reuse , Recycle !来作为文章的题目介绍了三个在环保再利用方面有突出贡献的人物及他们的做法。2a-2b主要关注课文的内容信息，2c-2d关注文中的语言信息。
二、学情分析：
对于变废为宝的DIY,学生基本上都做过。他们感兴趣，并且很有创新精神。所以本节课的文章，学生理解起来并不难。只是文章较长，在教学过程中，可以利用思维导图来帮助学生梳理和获取文本信息。此外，九年级学生对衍生词已经非常熟悉，本节课中出现了很多带词缀的单词，教师应结合以前学过的类似词汇帮助学生归纳和总结。在归纳和系统学习中，学生的自主学习能力将会有很大的提升。
