Unit3Computers

I.教学内容分析本单元以computers为话题，旨在通过单元教学，使学生了解计算机和信息技术的产生和发展过程及其在我们的学习、工作、娱乐等生活中所起的重要作用，激发学生对信息技术的兴趣。

1.1Warmingup提供几幅与计算机有关的图片，形象地说明了计算机的发展历程，并用三个问题引发学生对这一话题的思考，从而起到热身的作用。

1.2Pre-reading根据文章内容预设问题，检查学生对computers相关知识及应用的了解,这更能激发学生想获取更多知识的欲望，从而引出下面的阅读文章——WHOAMI?

。

1.3Reading中以别致的标题WHOAMI?

引起学生的好奇心，使学生迫不急待地阅读这篇文章，并判断出“I”是computer，从而对文章的内容印象更深刻。

文章以第一人称的形式按时间先后顺序讲述了computers的产生、发展和现状，并用拟人化的口吻表达了computers乐于为人类服务的精神。

1.4Comprehending1通过scanning的方式完成反映计算机发展历程的时间进程；2通过填表的形式帮助学生宏观梳理文章结构，找出每个段落的主题句（论点）及具体的支持性论据；3是读后讨论，要求学生结合自己的生活实际讨论计算机如何改变了我们的生活。

1.5Learningaboutlanguage分词汇（Discoveringusefulwordsandexpressions）通过各种形式练习本单元的重点词汇和短语,语法（Discoveringusefulstructures）两大部分。

USINGSTRUCTURES设计了各种活动练习巩固本单元的语法项目。

1.6USINGWORDSANDEXPRESSIONS1.8WRITINGTASK是写作任务，学生根据所给范文和2中的notes写篇文章，介绍自己设计的机器人。

或根据采访活动内容和范文结构提示写篇采访稿。
