Period5

SectionB（3a－3b）&SelfCheck

本单元围绕“发明”这一话题，学习了解一些重要发明的历史，教学一般过去时的被动语态。

SectionA介绍了我们日常生活中的一些常见物品的发明历史，如电视、电话、拉链、茶叶等。

内容上包括谈论它们的发明时间、被什么人发明、它们的作用和发展等；从语言结构上，学习被动语态的过去时，单元主题图由四副小图组成，呈现的是现代生活中的常见用品：

电视、电话、电脑和小汽车。

从运用Ithinkitwasinventedbefore/after…讨论图片中物品发明的先后顺序开始，到听说训练本单元的重点语言结构：

Whenwasitinvented？

Itwasinventedin…，Whowasitinventedby？

Itwasinventedby…，Whatwas/isitusedfor？

Itwas/isusedfor…不断深入学习，再进入阅读训练，训练学生的阅读技巧，学习拓展词汇和语言结构。

SectionA的重点是培养学生运用被动语态的意识，掌握更多的动词过去分词形式。

SectionB依然围绕发明创造这个话题，要求学生继续学习巩固相关的内容和语言知识。

在语言技能方面，对听说读写的专项训练和综合训练在本部分里都有体现。

在语言策略上，提出让学生学习使用思维导图，以加深对文章的理解和对知识的记忆。

在听力训练过程中，需要学生运用反义词、信息综合判断等，训练捕捉信息、处理信息的能力。

在阅读训练中，需要学生学习和掌握如何利用思维导图帮助理清、记忆阅读语篇中的相关信息，把获取的信息转换成图形来帮助记忆。

积极运用阅读策略有助于学生更好地掌握文章要点和细节等信息，降低语篇的学习难度，也有助于培养学生主动学习的习惯。
