Book 2 Unit 3Computers Learning about languages----Revision 教学背景分析单元结构分析与处理

单元结构分析与处理

【主题】人与社会——计算机

【语篇类型】科普说明文“Computers（Who am I）” 【授课时长】两课时（每课时45分钟）

【语篇分析】

【What】本单元阅读文章是以主要讲述计算机发展史及其应用的科普说明文，文章内容抽象、知识性强，特别是其中一些专业术语对高一学生而言确有难度。

【How】文章内容特点，每段句首是该段主题句。第一、二段以时间为线索，着重介绍计算机的发展历史；第三段介绍了计算机在当今社会各领域中的运用。在阅读过程中，学生通过寻读（scanning）按照时间顺序，理清计算机发展的历史脉络，进而理解计算机在不同发展阶段社会各领域中的应用。重点词汇主要涉到计算机的专业词汇。

【Why】本篇文章是讲述计算机发展历史及其应用的科普说明文，其主旨是表达计算机发展变化之快以及在生活中的用途之广。通过本节课所学，能够流畅用英语表达各自想象中的未来机器人，进而升华本堂阅读课的内涵和外延。

【语言知识】

语音：听的录音，让学生模仿标准地道的语音语调，掌握正确的语音、语调和朗读技巧，在口语表达中做到语音、语调自然和流畅。

词汇：涉及到计算机的专业词汇(calculate, network, analytical, universal)、表明态度（totally, anyway )、核心动词短语(deal with ,go by..)等

语法：现在完成被动语态（present perfect passive voice）

语篇：计算机（第一人称，时间顺序，条理性，真实性，准确性）

语用：理清计算机发展的历史脉络，进而理解计算机在不同发展阶段社会各领域中的应用。能够流畅用英语表达各自想象中的未来机器人。

【文化知识】：了解计算机发展的历史脉络，进而理解计算机在不同发展阶段社会各领域中的应用。了解这种以计算机为核心，集网络文化、信息文化、多媒体文化于一体并对社会生活和人类行文产生广泛、深远影响的新型文化。

【语言技能】：理解性技能（读、看）；表达性技能（写、说）

【学习策略】：1）利用互联网，查找背景资料，了解计算机的发展历程 2）通过设置与教学相关的“数博会”教学情境，大大激发学生的学习积极性和主动性。

联系学生实际，为学生学习层层搭建“脚手架”并构建思维导图：以时间为线索，获取计算机发展史知识脉络和计算机应用的细节信息。

3）采用色扮演这一活动来充分调动学生们的学习的兴趣,首先缩写了带有重要知识点的reading, 然后就不断的要求学生重复, 在这段文字中挖掘宝贝, 以重复的方式不断以最新的考试题型出现,通过学生自主学习及合作探究等学习方式让学生真正学会并能够运用这些知识点于实际的英语学习中去。

4）根据主题内容，采用了自主学习, 合作探究, 启发引领, 再现语境学习是贯穿整节课的一条脉络建构词汇网

5）通短文翻译练习，让学生们能够在具体的语境下，尽可能多的地串联起本单元的重点词汇，充分调动了学生学习积极性和主动性，使其能够正确熟练的运用课堂所学内容来表达各自的想法，进而升华到本堂词汇课的内涵和外延，真正落实高中英语学科核心素养。

二、学情分析：

1）计算机这一话题对于高一学生而言并不陌生，但本篇文章属于科普说明文，内容抽象，多数学生在理解和整合知识、逻辑推理和分析论证观点以及批判评价方面的能力还比较欠缺。

2）害怕犯错，不愿意积极主动的发言，所以教师要运用积极词汇，多鼓励学生发言；

3）对“计算机”这一话题非常熟悉、能够激发学生的学习兴趣；

授课时长：两课时+课外学习 三、教学目标与教学重难点：

从事英语的教学工作多年, 我深知一轮复习的重要性, 也深知复习课对于教师和学生来说都是一个难题,如何高效而有趣的复习,既能突出重难点,又能减少学生学习压力, 帮助他们最快最准达到复习的目标一直都是我研究的地方. 这节课, 我做了一个词汇复习课的探究, 采用角色扮演的方式，调动孩子们复习的兴趣, 我首先缩写了带有重要知识点的reading, 然后就不断的要求学生重复, 在这段文字中挖掘重点, 不断以最新的考试题型复现文章, 并采用自主学习、合作探究等放松的学习方式让学生真正学会运用这些知识点于实际的英语学习中去。
