【公开课教案Unit 3 Reading and writing 人教版(2019)选择性必修第二册
O2U3 Food and Culture 教学设计（一）教学背景概要性写作是高考写作题型的一种。
概要性写作在高考中出现的频率不如读后续写高，因此受到教师和学生的重视不足，学生在概要性写作时的表现往往不如读后续写，对于概要性写作的结构、功能句式以及句子转写技巧不熟悉。
部分教师在教学时，不能引导学生对文本进行分析从而梳理写作思路，只依照答案范文为学生进行分析，灌输应试技巧，造成了学生语言输入不足，写作框架缺失，写作思维匮乏的现象。
如何通过对文本的分析和梳理习得概要性写作中的结构框架、功能句型和写作技巧，从而实现写作产出与原文之间的语句通顺、逻辑相通，成为不少教师的困惑。
鉴于此，本课例使用高中英语“三段七步”读思写整合教学模式，以教材文本为例，探讨新教材背景下，高中英语概要性写作如何实现写前结构、语言、技巧等支架的搭建，从而如何实现阅读与写作的目标一致。
（二）教学分析1、教学内容分析本课教学内容选自2020人教版普通高中英语教材选修二第三单元Food and Culture的Using Language板块。
本单元阅读文本的主题是饮食和文化，主题语境为人与社会。
该语篇是一篇议论文，以健康饮食为主题，解读了什么是健康饮食、怎样进行健康饮食，旨在让学生了解健康的饮食方式。
正文内容遵循“总-分-总”的结构。
第一段为总起段。
第二段至第四段，作者列举了三种健康饮食的方法，并通过引用、列数据等方法使自己的论证更加具有信服力。
在上述列举的基础上，作者在最后一段进一步对健康饮食的核心进行了解读，对文章进行了总结。
就文体特征来看，该文本论述主题和论述过程准确、鲜明、严密、有针对性，按照总-分-总的方式开展议论，段落与段落之间有着较清楚的逻辑关系，每个段落内也存在清晰的结构关系。
该文本中的第二段到第四段按照逻辑顺序，围绕文章的中心，列举了三种健康饮食的方式，是一篇适宜进行概要性写作的文本；就语言来看，该文本使用了起过渡性作用的语句或关联词，如“however” “beyond this” “finally” “in other words”等，为学生在写前环节进行衔接手段的学习提供了语言支撑；就内容来看，文章话题为健康饮食，属于常见的话题，在内容上贴近学生生活，方便学生阅读和理解。

新人教必修2 Unit 3 THE INTERNETReading and Thinking: Stronger Together: How We Have BeenChanged by the Internet文本简析本单元阅读文本的话题是互联网对人们的积极影响：互联网不但给人们的生活带来便利，而且能促进人与人之间的相互帮助，使人们变得更加强大。
该文本是叙事性文本，讲述了英国一位名叫简的英语教师辞职后，借助互联网得到了帮助，并主动帮助他人的事例。
从表层意义讲，文本讲述了互联网是如何改变人们的生活方式的；从深层意义来看，本文进一步表达互联网带给人与人之间的“连锁反应”：互联网作为媒介，连接着人与人之间的互助，激发着人们积极向上的正能量，传递着人们之间的互相关爱。
全文共五段，文本结构清晰。
第一段阐明了互联网带给人们的积极影响；第二、三、四段讲述了简失业在家及接触互联网后心理和行为上的变化；第五段通过简自己的话语，解释了她愿意帮助别人的原因，体现了相互帮助带来的积极效应。
本文可以围绕标题中的关键词“change, stronger, together”展开教学，主要通过静默阅读提取文本信息、提问处理相关语言、人物鉴赏学习优秀品质、写作迁移训练语言能力等几个教学策略达到本文的阅读课教学目标。
第1课时一、教学内容提取标题中“stronger, together, change”和“Internet”四个关键词。
梳理关于互联网、人物和描述变化的语言。
抓住“变化”主线，梳理文本，系统化地处理信息。
二、课时目标1. 通过分析标题关键词，理清标题与文本的内在联系，掌握文本主要内容。
2. 理解表示变化、互联网等的话题语言，能够在关键词的帮助下，复述主人公简的故事。

Read through three topics on page 33 and choose one topic to write about.
Introduction
Tell the reader about yourself and what you know about the topic.
Version 2 Hello, everyone. I’m a senior high school student. Today I want to blog about something that I think is very important. Unfortunately, I know about the topic well because I made a silly mistake. That was to make my email password “password123”! About six months ago, someone hacked my email account. That means they found out my password, then tried to use my account to take money from me and sent viruses to all my contacts! Luckily my friend told me when she got a strange email from me, so I changed my password immediately. I read about how to make a good password. A good one should have a mixture of both upper case (large capital) letters and lower case (small) letters, numbers and other characters. It also should not be a name or date or anything someone can guess. It should be completely random, that is, it shouldn’t make sense! Although it can be hard to remember lots of complicated passwords, it is worth it! These days you can also use a password manager. This is a special program that helps you manage passwords for all your different accounts. Although I hope nothing similar has happened to my readers, please comment if you have had a similar experience or if you have any more good ideas about making your passwords super safe! Catch your later!
