comparison and contrast写作教案

New Century English S2B

Ways of organization---comparison and contrast 设计者 崇明县堡镇中学 陈洁 2015/5/6

【教材分析】

本课的任务是用比较与对比的手法写作。本单元恰好学习了两位科学家，爱因斯坦和袁隆平。两篇课文分别从人生经历、主要成就以及性格爱好等方面介绍了两位科学家，这两篇课文提供了很好的语言素材，学生们学完后可以对这两位科学家进行比较与对比的写作。

【学情分析】

学生学完两篇课文之后，对两位科学家已经比较熟悉，并且能够用所学短语句型对两位科学家做简单介绍。但是学生对比较和对比这一写作手法是完全陌生的，还不会用表示相似与不同的连接词来连句成文，对两位科学家作比较与对比的写作。

【教学目标】

By the end of the activities, the students are expected

 to tell whether a paragraph is comparison or contrast and find the connecting

words used in comparison and contrast  to find some differences and similarities of Einstein and Yuan Longping by using

the connecting words such as while, however, in contrast, similarly, in the same way, etc.

 to write a paragraph about Einstein and Yuan Longping by comparison and

contrast 【活动设计】
