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。

人教版高中英语必修二Unit3Computer语法探究

高中英语学习材料（灿若寒星*制作整理）Unit 3 Computer语法探究The Present Perfect Passive Voice现在完成时被动语态由”has/have + been + 及物动词的过去分词”构成。

使用现在完成时被动语态要注意以下几点：1. 只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被动语态的主语。

例如：We have built many houses in the past ten years.→Many houses have been built in the past ten years.2. 带有双宾语的动词，如give, send, bring, take, teach, show, tell, make, sing, write, read, sell, buy, tell, pay, lend, pass, promise等，变为被动语态时，可将其中一个宾语变为主语，另一个保留不动。

例如：We have given him the book.→He has been given the book.→The book has been given to him.3. 带有复合宾语的动词变为被动语态时，只能将宾语变为主语，原来的宾补改为主语补足语。

原来省略to的不定式作宾补的，被动语态中要用带to的不定式。

例如：I have told them to help you.→They have been told to help you.I have made her work hard.→She has been made to work hard.4. 短语动词变为被动语态时，要注意保持短语的完整性，动词后原有的介词或副词不可遗漏。

How much do you know about it? What is the Internet? The Internet is a large, worldwide collection of computer networks. A network is small group of computers put together. The Internet is many different networks from all over the world. These networks are called the Internet. Once you have learned to use the Internet, you can do a lot of interesting things on the World Wide Web. What is the World Wide Web? The World Wide Web has been the most popular development of the Internet. The Web is like a big electronic book with millions of pages. These pages are called homepages (主页). You can find information about almost anything in the world on these pages. For example, you can use the Internet instead of a library to find information for your homework. You can also find information about your favorite sport or film star, talk to your friends or even do some shopping on the pages. Most pages have words, pictures and even sound or music. What is e-mail? Electronic mail (e-mail) is a way of sending messages to other people. It’s much quicker and cheaper than sending a letter. If you want to use e-mail, you must have an e-mail address. This address must have letters and dots and an “@” (meaning “at”). Thisiswhatanaddresslookslike:**************.Write a message, type in the person’s e-mail address, then send themessage across the Internet. People don’t need to use stamps, envelopes or go to the post office since the invention of the Internet. Quick, easy and interesting—tha t’s the Internet! () 1. What is the Internet? A. It’s a big computer.B. It’s a small group of computers. C. It’s lots of computer networks.D. It’s the World Wide Web ()2. What does “ talk to your friends on the pages” mean? It means_____ A．you can talk to your friends face to face B．you can type your words in the computer and then send them to your friends across the Internet C. you talk to your friends through the same computer D. you go to your friends’ houses to talk to them () 3. Why do people like to use e-mail to send message to their friends andfamilies?Because_______ A. they don’t have to pay any moneyB.it’s faster and cheaper C. they don’t need to have stamps, envelopes or addressD. sending e-mail is interesting () 4. What does the “e” mean in e-mail? It means______ A. easyB. electricalC. electronicD.enjoyable B How toprotectchildren Webfans fromunsuitable material on-line while encouraging them to use the Internet has long been discussed in US. For some parents the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as hazards and, with good guides, some education and a few precautions (预防措施) the wilds of the Internet can be safely navigated (航行). Kids have to be on-line. If we tell our kids they cant have access (进入) to the Internet were cutting them off from their future, said an expert. Most kids have started to learn to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. But themost popular that was to limit access would be to use what is known as a content screener (过滤). But this cant be wholly reliable, and the best thing parents can do is to talk to their kids and let them know whats OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing (扫瞄) the Internet. A few other tips: ●Dont put the PC in a childs room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity. ●Ask your child what he文档内容到此结束，欢迎大家下载、修改、丰富并分享给更多有需要的人。
