2.学会讲故事。

3.能够阅读本单元提供的相关阅读材料；能够阅读各种通话、传说和经典故事。

4.能够续写故事；会写简单的故事和戏剧。

【学习内容分析】（分析知识点在知识体系中的地位和作用；分析知识的应用价值；分析知识对学生的情感熏陶及能力、思维培养上的作用）本单元围绕“传说和故事”这个话题，谈论过去发生的事情，重点训练“讲故事”这个语言功能项目。

通过学习，要求学生掌握如何用过去时态讲述一个故事，描述古老的传说和有趣的故事，激发和培养学生学习英语的兴趣，理解并体会传说和故事的教育意义。

在了解目标语言的基础上，要求学生能理解优美的传说和有趣的故事，掌握故事的基本结构，讲述自己喜爱的故事。

Section A主要围绕愚公移山和美猴王的故事展开，使学生学会用一般过去时表达故事，并用unless， as soon as，so...that...＂引导的状语从句来连接故事，培养学生坚忍不拔的品格和助人为乐的精神。

让学生通过了解故事的情节发展，捕捉关键信息，使学生能用讲故事的形式进行恰当输出。

【学情分析】（分析知识生成点及新旧知识的关联，预设学生学习困难）初二学生已经学习了一般过去时的用法，这也是学生常用的时态之一，也听说过《愚公移山》、《女娲补天》、《皇帝的新装》等故事。
