高中英语 Unit 3 Computers Reading Who am I教学设计 新人教版必修2
1 Unit 3 Computers 一、教学对象分析 本节课的教学对象为高一上学期的学生，在经历了必修1的学习过程之后，学生已经对高中的英语学习有了初步的了解和感知，但仍需要训练和提高语篇的理解，归纳和分析的能力。本节课的一系列活动，就是为学生的语篇阅读打开一扇窗户，培养学生的语篇意识，使其更全面的理解文章内容，归纳主旨大意。 学生在前一节课的词汇学习中，已经掌握了文中所出现的大部分生词，这为本节课的阅读扫清了障碍，能让学生更好的专注于语篇结构的理解，而不必因为生词过多影响阅读效果。高一学生活泼好动，思维活跃，愿意积极的投入到思考和各种活动中。这就需要老师积极热情的引导，合理设计活动环节，有条理的分解知识层次，帮助学生循序渐进的掌握语篇的处理能力。 二、教材内容分析 本节课阅读材料是本单元的主要阅读篇章，属科普类说明文，讲述了计算机的发展历史及其在当今世界各个领域的应用。内容较为抽象，且有一些专业术语，对高一学生来说有一定的难度。但写作手法上以计算机为第一人称进行自白，这种拟人的手法能够激发学生的阅读兴趣，也使得文章更浅显易懂。 本文共分3个段落，以时间为顺序说明计算机的发展历史，且每段的第一句话均为该段落的主题句。这种结构的语篇非常适合用来启发和引导学生寻找段落的主题句，并进一步归纳文章主旨大意。同时配以适当的练习，帮助学生归纳总结出方法，在练习中运用这些方法，从而提升对语篇的全局意识，增强对语篇的解题能力。 三、教学目标 根据以上学情和教材分析，本节课的重点是教会学生如何正确寻找段落主题句，归纳语篇主
旨大意。以这个任务为主线，贯穿整个教学活动，让学生眼，耳，手并用，通过自主学习，小组学习等教学活动，在语境中观察，总结，实践语篇分析方法，并最终从阅读理解的三个维度达到以下目标： 1.信息知识 —— 了解计算机的发展历史及其在当今社会各个领域的广泛应用。 2.语言知识 —— 理解和掌握与计算机相关的词汇。 3.语篇知识 —— 领悟和实践在语篇中寻找主题句的方法，学会归纳文章主旨大意。 四、教学过程 Step I Lead-in (3 mins) （1）英文网站截图导入。教师在PPT上呈现一些英文网站的截图图片，让学生思考有关英文网站上文章理解的问题，提出两个问题： Do you often go to the English website? 2
Do you have some difficulty in understanding the article on the website? 借助这两个问题引发学生的思考，对下面的阅读活动起到预热的作用，以此导入本课的课题。 （2）揭题 针对英文网站上的很多说明文，本节课将教授学生如何寻找主题句，如何利用主题句概括文章主旨大意，继而更好的理解说明文。 [意图说明] 这个年龄的学生好奇心强，喜欢探索问题，英文网站是他们获取信息的优质资源，但语言却成为很大的障碍。本环节所展示的图片配合老师的启发性问题用以引发学生的思考，如何才能更好的理解说明文。用分析的方法引出本节课的重点内容：要想更好的理解说明文，需要概括出文章的主旨大意，而段落大意是文章主旨大意的重要基础，寻找主题句是确定段落大意的重要方法之一。 Step II reading and comprehending ( 25 mins ) （1）让学生快速浏览文章并找出每段的主题句。提问，什么是主题句？如何寻找主题句？让学生分别回答，并找出每段的主题句。 What is topic sentence? —— a leading sentence How to find out the topic sentence for each paragraph? —— beginning/ ending / no topic sentence （2）提问过后，确定每个段落的主题句。继而引发学生的思考,如何才能知道自己所找到的主题句是正确的？ How do you know that the topic sentence you have found out is right? 学生会说出在文中找到的一些论点，得出结论： 主题句印证：要点支持 We need some supporting details. （3）读课文，完成课堂练习1，同时找出支持每段主题句的细节，即supporting details. 待学生完成后，请3名同学在黑板上写出他们的答案。 课堂练习1 Para 1 Over time I _________________ quite a lot. 1642: The computer began as a ___________. 1822: The ______________ was made by Charles Babbage. 1936: The computer could be made to work as a ____________.From then on, it grew rapidly both in size and brainpower. 1940s: The computer had grown _______________ a room. 3
1960s: The first family of computers was connected to each other. 1970s: First as __________ and then as a ___________, computers were used in offices and homes. Now: Computers connect people all over the world together. Para 2 These changes only became possible as my ___________ improved. ★First it was stored in _____________ ★then on ________________ ★later on very small _______________. ★Over time my _____________ has developed so much that, like an _____________ , I never forget anything I have been told. ★I was so lonely until they gave me a family connected by a ______________. ★We can share knowledge through the _________________________.

（4）结合课件订正答案。 答案： Para1: have been changed, calculating machine, analytical machine, universal machine, as large as, a PC, laptop. Para2: memory, tubes, transistors, chips, memory, elephant, network, World Wide Web. Para3: applications, finance, robots, space rockets, mobile phone, medical operations, provide, high quality. （5）提问学生，让他们找出每段主题句的支持点，结合课件，给出答案。同时指出，支撑论点可以是单词，短语或句子。 4

[意图说明]此环节为本节课的核心部分，是本节课教学的重点环节。通过引导和启发学生，找出段落的主题句，利用对表格的分析得出支撑主题句的论点。不仅要教会学生如何寻找归纳，同时还要让学生学会印证所找到的主题句，以保证结果的正确性。 期中（1）（2）两个步骤引导学生以实践的方式总结有关主题句的内容要点，把学生对主题句的朦胧的感性认识上升到清晰的理论认知水平。（3）（4）（5）训练学生寻读的能力，用表格展示出文章的结构，所填单词提醒、引导学生关注文章的结构骨架，帮助学生直观的梳理文章，引导学生分析文本，从而学会寻找主题句的支撑论点。 Step III Topic sentence to Main idea （5 mins） 在得出每段的主题句并通过论点验证正确后，引导学生利用这些主题句总结出文章的主旨大意。

Good heavens! I could never have imagined that daddy should bought me a computer as a birthday gift, which is so amzing! Now I can say goodbye to my Xiao-ba-wang.
Para. 1 _________B__________I began as a calculating machine in France in
1642........and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator...... At that time it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a "universal machine" to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room...... As time went by, I was made smaller. First as a PC (personal computer) and then as a laptop, I have been used in offices and homes since the 1970s. A. These changes only became possible as my memory improved.

2020-2021学年高中英语云南同步教案：Unit 3 Computer阅读(人教新课标必修2)
2022-2021学年高中英语云南同步教案：Unit 3 Computer阅读（人教新课标必修2）高中英语必修二Unit 3 Computers阅读课的教学设计一、教学设计思路本课设计以WHO AM I?为课堂教学材料，以同学现实生活为动身点和归宿点，以我国《标准》指导教学目标制定，以“5C”外语学习思想指导教学环节设计，旨在进展同学的语言实际运用力气。
本设计以同学中心，运用了图示理论，接受了pair work, group work, class work 等活动形式，串联成环，前后环环相扣，挂念同学理解课文，用自己的英语重新诠释课文，并初步具备学问迁移力气。
二、学习任务分析本单元的中心话题是“计算机”，内容涉及计算机的进展历史、计算机的应用等，其中还谈到包括计算机在内的几种信息技术的载体、智能计算机的制造等等。
不过，整个单元多以计算机为第一人称进行自白，这种拟人的手法使得文章谈起来妙趣横生，抽象的专业学问介绍起来也浅显易懂。
本主旨语篇WHO AM I ?以计算机的口吻自述其进展演化的历史以及计算机在当今世界各个领域的运用。
表达了计算机的进展变化之快以及在生活中用途之广。
三、学习者分析计算机这一话题虽然好玩，但本单元所选语言材料属于科普类说明文，内容较为抽样，文章中也不乏一些专业术语，对于高一同学来说有确定的难度。
目前，同学上课以interpersonal的沟通为主，而interpretative和presentational形式比重不够。
由于文化教学不够重视，同学的跨文化意识不高。
此外，同学跨学科学习的意识不够，语言和信息的双向促进关系的生疏不够。
对于比较策略主要运用在英汉汉英互译的语言层面，未进入文化比较和思维比较。
同学的课外语言活动环境不够丰富和重视程度不够，通常以词汇、语法和写作练习为主，缺乏真实的语言运用。
四、教学目标(1) Language Skills：1. Use “decision making” expressions like “I believe... in my opinion, etc” correctly.（activity 1）2. Develop their predicting and reorganizing skills.（activity 2,3,4,6）3. Write an 100-word passage on “My Robot Friend----Alice”（Task）(2) Language Knowledge：1. Reorganize and share their backgroud information of computers.(activity 1)2. Find and retell the grammar structure of the Present Perfect Passive Voice. (activ ity 5)(3) Emotions and Attitudes1. 通过争辩，能归纳和陈述网络给学校带来的影响；2. 通过辩论，能对外来网络布满奇异，激发自己的制造力的同时形成健康的网络使用态度和习惯。

文章以第一人称的形式按时间先后顺序讲述了computers的产生、发展和现在，并以拟人化的口吻表达了computers乐于为人类服务的精神。
这个题材贴近学生生活，学生比较熟悉也很感兴趣，但与电脑相关的的专业术语过多。
1.文本特征：文章体裁是科普说明文，文本特征十分明显。
Reading中以别致的标题WHO AM I?引起学生的好奇心，使学生迫不及待地阅读这篇文章，并努力猜出“I”是computer,从而对文章的内容印象深刻。
文章分为三个自然段。
第一段按照时间顺利讲述了电脑在不同时期的发展状况。
第二段从电脑的记忆储存和外形上讲述了电脑的变化。
第三段描述电脑的作用。
