高中英语必修二Unit 3 Computers阅读课的教学设计方案
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，以学生现实生活为出发点和归宿点，旨在发展学生的语言实际运用能力。
本设计以学生中心，运用了图示理论，采用了pair work, group work, class work等活动形式，串联成环，前后环环相扣，帮助学生理解课文，用自己的英语重新诠释课文，并初步具备知识迁移能力。
二、学习任务分析本单元的中心话题是“计算机”，内容涉及计算机的发展历史、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、智能计算机的发明等等。
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，抽象的专业知识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发展演变的历史以及计算机在当今世界各个领域的运用。
表达了计算机的发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有趣，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，对于高一学生来说有一定的难度。
目前，学生上课以interpersonal的交流为主，而interpretat ive和presentational形式比重不够。
由于文化教学不够重视，学生的跨文化意识不高。
此外，学生跨学科学习的意识不够，语言和信息的双向促进关系的认识不够。
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。
学生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.（activ ity 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 comp uters.(activity 1)2. Find and retell the grammar structure of the Present Perfe ct Passive Voice. (activity 5)(3) Emotions and Attitudes1. 通过讨论，能归纳和陈述网络给学校带来的影响；2. 通过辩论，能对外来网络充满好奇，激发自己的创造力的同时形成健康的网络使用态度和习惯。

Unit 3 Computer 教学设计Period 1: Warming up and readingTeaching AimsTo talk about computerTo read about computerProceduresI. Warming upWarming up by talking about computerLook at the pictures on page 17. What are they? What dothey have in common? Yes, they are computers. Then whatis a computer?A computer is a machine which stores knowledge in its memory and does calculations on thatknowledge. This knowledge is stored in symbols; it is called data. A computer usually has a monitor to show results. However, some computers can speak; these computers can be used for voice mail.计算机室A computer frequently requires a boot device. The boot device contains the computer’s operating system and data. Computer programs can be installed onto a computer. Some people think that computers are less useful if they do not have access to the Internet. They think this because the Internet allows the computers to send and receive data and email across the world.曙光3000巨型计算机A computer is now almost always an electronic device. It usually contains materials which are toxic; these materials will become toxic waste when disposed of. When a new computer ispurchased in some places, laws require that the cost of its waste management must also be paid for. This is called product stewardship.In some countries old computers are recycled (melted down) to get gold and other metals. This is dangerous, because this procedure releases the toxic waste into the water and soil.Computers become obsolete quickly. Very often they are given away and new ones replace them within two or three years. This makes the problem worse. Computer recycling is thus common. Many projects try to send working computers to developing nations so they can be re-used and will not become waste as quickly.II. Pre-reading1. Questioning and answering---What do you know about computer?●Electronic machine capable of performing calculations and other manipulations of varioustypes of data, under the control of a stored set of instructions. The machine itself is the hardware; the instructions are the program or software. Depending upon size, computers are called mainframes, minicomputers, and microcomputers. Microcomputers include desk-top and portable personal computers.●A multi-function electronic device that can execute instructions to perform a task.●A device that accepts information, processes it, and supplies an output. A computer usually contains memory, a control unit, arithmetic and logical units, and a means for input and output.●a programmable hardware component that is controlled by internally stored programs and that can perform substantial computations (including arithmetic and logic operations) without human intervention. A computer typically consists of one or more processing units, memory units, and associated peripheral input and output devices.●Related to automation and electronic data processing. The Library of Congress commonly classes most computer-related books in HF5548, QA75-76, Z52, T385, and some TK ranges.●a machine for performing calculations automaticallycalculator: an expert at calculation (or at operating calculating machines)●A computer is a device or machine for making calculations or controlling operations that are expressible in numerical or logical terms. Computers are constructed from components that perform simple well-defined functions. The complex interactions of these components endow computers with the ability to process information. If correctly configured (usually by, programming) a computer can be made to represent some aspect of a problem or part of a system. If a computer configured in this way is give2. Discussing and sharing---How have computers changed our lives?Someday soon, if you haven’t already, you’re likely to plug into the computer network nation growing in our midst. Computer terminals, or small computers connected via modem (a modulator/demodulator circuit for encoding/decoding computer chatter) to ordinary telephone lines, should be as ubiqu itous as the telephone itself. They’re a much more useful and humane tool than the phone, and with corporate America behind them the networks will be everywhere----changing our lives more than any technology since the automobile. Joining a computer network is the same as joining a community. Small systems are like villages, where new members are formally welcomed. The larger networks, the Source and CompuServe, for example, are cities-anonymous, full of life and events, but difficult to fit into.III. Reading1. Listening and reading to the recording of the text WHO AM I?Turn to page 18 and listen and read to the recording of the text. Pay attention to the pauses, pronunciation and intonation of the native reader.2. Reading aloud and underlining expressionsNow we are to read the text once again and underline all the expressions in the text. Put them down into your notebook after class as homework.Collocations from WHO AM I?begin as…, a calculating machine, be built as…, at that time, a technological revolution, the start of artificial intelligence, write a book, be made to work, solve problems, from then on , grow any large r, As time went by, go back to…,be made smaller, memory became so large, stand there by oneself, be connected by…, share knowledge with others through…, be put into…, provide humans with…, deal with…, truly filled with…3. Reading, identifying and settlingAttention, please! It is time to skim the text one more time and identify the difficult sentences. Try analyzing the structures of the difficult sentences and discuss them among your group members.You may also put your questions to me for help.IV. Comprehending1.Scan the text for information to complete the table below, describing the development of computer.2.Read the text again and complete the chart below.Period 2: Learning about Language Teaching Aims:To learn to use The Present Perfect Passive V oiceTo discover useful words and expressionTo discover useful structuresProceduresI. Warming up by reading to the tapeTo begin with, turn to page 18, listening to and reading to the recording of the text WHO AM I? Attention goes to the pauses and intonation, as well as the pronunciation of the reader.II. Discovering useful words and expressionsIn pairs do the exercises 1, 2 and 3 on pages 20. You must finish them in 10 minutes.III. Learning about grammar1. Passive Voice—Overview2. The Present Perfect Passive VoiceThe structure of The Present Perfect Passive Voice is: have/ has ＋been＋~edIV. Reading aloud and discoveringNow go back to page 18 to read aloud and discover in the text examples of The Present Perfect Passive V oice.V. Discovering useful structureWe shall do grammar exercises 1, 2 and 3 on page 21.VI. Closing down by doing a quizCorrect the mistakes in these passive voice sentencesExample: The house was build in 1880. (correct = The house was built in 1880.)1. 3000 employees were laying off.2. A story will made up.3. An idea was putted forward for discussion.4. Has the book been give back to you yet?5. My bank loan will be payed off in five years time.6. Nothing can be hold against me.7. Our allies will be lend support.8. She has never heard of.9. She was being knocked down by a bus.10. She was letted off with a fine.11. The candle was blow out by the draught.12. The criminal were locked up.13. The flood water was be kept back by barriers.14. The inconvenience will made up for by this money.15. The keys must have been being left behind.16. The old cinema is being pull down.17. The protesters being held back by the police.18. The road was blocking off.19. Thirty more people were laid off last week.20. Your jacket can be hanged up over there.Period 3: Using Language Teaching Aims:To discuss about ITTo write a report about ITTo read about androids or robotsProceduresI. Warming up by talking about ITWhat is Information technology?Information technology (IT) or information and communication technology (ICT) is the technology requiredfor information processing. In particular the use of electroniccomputers and computer software to convert, store, protect,process, transmit, and retrieve information from anywhere,anytime.II. Listening and writingTurn to page 22. Discuss in pairs what IT consists of and then make a list. Listen to the text about different kinds of information technology or IT, discuss and write down in groups the advantages and disadvantages of each kind.III. Reading, speaking and writingIt is said that computers could be put into androids or robots. Read the text Andy—The Android, underlining all the expressions and think of the fun you could have!Speaking and writingSuppose you and your partner are going to help choose computers for your school. Now talk about the special things each of the computer can do and write a report to your headmaster.IV. Writing a letterSuppose you are an android. What would say to a spoiled child who would not do his homework? Write a letter to the boy.AndroidAn android is an artificially created being that resembles a human being. Theword derives from Greek Andr- ‘man, human’ and the suffix -eides used tomean ‘of the species, kind, alike’ (from eidos ‘species’).The word droid, a robot in the Star Wars universe, is derived from this meaning. Some people maintain that, etymologically, the word android means resembling a male human and that a robot resembling a woman should logically be called a gynoid for sexist language to be avoided; however, this word is not commonly used.Unlike the terms robot (a mechanical being) and cyborg (a being that is partly organic and partly mechanical), the word android has been used in literature and other media to denote several different kinds of man-made, autonomous creations:a robot that closely resembles a humana cyborg that closely resembles a humanan artificially created, yet primarily organic, being that closely resembles a humanAlthough essentially human morphology is not the ideal form for working robots, the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra (devices that exhibit likeness) and automata (devices that have independence). The term android was first used by the French author Mathias Villiers de l'Isle-Adam (1838-1889) in his work Tomorrow’s Eve, featuring a man-made human-like robot named Hadaly. As said by the officer in the story, “In this age of Realien advancement, who knows what goes on in the mind of those responsible for these mechanical dolls.”附：备课参考资料Computer BasicsTo accomplish a task using acomputer, you need acombination of hardware,software, and input.Hardware consists of devices,like the computer itself, the monitor, keyboard, printer, mouse and speakers. Inside your computer there are more bits of hardware, including the motherboard, where you would find the main processing chips that make up the central processing unit (CPU). The hardware processes the commands it receives from the software, and performs tasks or calculations.Software is the name given to the programs that you install on the computer to perform certain types of activities. There is operating system software, such as the AppleOS for a Macintosh, or Windows 95 or Windows 98 for a PC. There is alsoapplication software, like the games we play or the tools we use tocompose letters or do math problems.You provide the input. When you type a command or click on an icon, you are telling the computer what to do. That is called input.How They Work TogetherFirst, you provide input when you turn on the computer. Then the system software tells the CPU to start up certain programs and to turn on some hardware devices so thatthey are ready for more input from you. This whole process is calledbooting up.The next step happens when you choose a program you want to use. Youclick on the icon or enter a command to start the program. Let’s use theexample of an Internet browser. Once the program has started, it is ready for your instructions. You either enter an address (called a URL, which stands for Uniform Resource Locator), or click on an address you’ve saved already. In either case, the computer now knows what you want it to do. The browser software then goes out to find that address, starting up other hardware devices, such as a modem, when it needs them. If it is able to find the correct address, the browser will then tell your computer to send the information from the web page over the phone wire or cable to your computer. Eventually, you see the web site you were looking for.If you decide you want to print the page, you click on the printer icon. Again, you have providedinput to tell the computer what to do. The browser softwaredetermines whether you have a printer attached to your computer, and whether it is turned on. It may remind you to turn on the printer, then send the information about the web page from your computer over the cable to the printer, where it is printed out.II. TelevisionOld portable televisionA television (also TV or telly) is a device (tool) with a screen that receives broadcast signals and turns them into pictures and sound. The word “television” comes from the words tele (Greek for far away) and vision (seeing).Usually a TV looks like a box. Older TVs had large wooden frames and saton the floor like furniture. Newer TVs became smaller so they could fit onshelves, or even portable so you could take it with you wherever you went.The smallest TVs can fit in your hand. The largest TVs can take up a wholewall in your house, and may sit on the floor, or be just a large flat screen thatcan be mounted on the wall. Many TVs are now made in wide screen shape like movie theatre screens, rather than old, more square TVs.A television has an antenna (or aerial), or it has a cable. This gets the signal from the air, or cable provider. TVs can also show movies from DVD players or VCRs. TVs can be connected to computers and game consoles, usually through a kind of socket called “SCART”.III. Web or World Wide WebThe World Wide Web is the part of the Internet that contains web sites and web pages.It is not used to describe WebPages that are used offline where net services are not available, or no computer network exists - such as Wikipedia on CD. In this case no real physical site exists other than the place where the computer is. Blog and Wiki capabilities will also not be available because these require a communication with other computers.IV. RadioRadio is a communications invention. Though originally used tocommunicate between two people, it is now used to listen to music, news,and people talking. Radio shows were the predecessor to TV programs.V. DVDDVD most commonly stands for “digital versatile disk”. It can playvideo that is of a higher quality than a VHS tape.VI. Two kinds of DVDThey can also hold 4.7 GB of information as opposed to the 700 MB that a CD can hold. A plus of using a DVD for a video is the ability to have interactive menus and bonus features such as deleted scenes and commentaries.VII. EmailEmail (electronic mail) is a message, usually text, sent from one Internet user to another. Email is quicker than snail mail(mail) when sending over long distances and isusually free. To send or receive an email, a computer with a modem andtelephone line connected to the Internet, and an email program arerequired. Email addresses are generally formated like this: login@server.(com or fr or org or uk or other).Some companies let you send and receive email for free from a website. Gmail, Hotmail and Yahoo! do this.VIII. HumanHere are two humans.A man is on the left and a woman is on the right. A human or human being is a person, like you. A male human is a man, a female human is a woman. If you think about all humans in the whole world, they are called humanity. In the past, people have also used man and mankind to mean all humans.Humans are called Homo sapiens by scientists. Humans are an animal species that belongs to the group called primates. Monkeys are primates too, but the primates most like people are gorillas and chimpanzees. Most scientists think that chimpanzees and humans came from a common ancestor by what is called evolution. Other animals even more like humans than chimpanzees once lived too, but they are now extinct.Human rights are those things that everyone deserves and the way they should be treated by other people.。

听的部分是通过强调听力技巧，通过“听前”“听中”“听后”让学生提高听力效率，了解三则广告中三种不同机器人的信息。
说的部分是在一定的情境下，通过学生小组合作编对话的形式为自己的家庭选择一款适合的机器人并表明原因。
三、学生情况分析作为高一的学生，对电脑和机器人方面的知识应该已经有所了解和熟悉，也具备些相关的词汇和表达，而且这个话题也是学生所较感兴趣的话题之一。
但是，很多同学对于听说是存在畏惧感的，特别是高考对于英语综合能力的考察日益增强。
语音是否准确，语速是否流畅，是否能听懂信息进行问答，能否及时记录关键信息点进行语言输出等等这些情况都是我们老师在听说课活动中要考虑到的实际问题。
同时，还有些学生缺乏自信，不愿开口，担心出错等等，那么教师所设计的活动要求就要由浅入深，层层递进，逐步培养和提高学生运用英语进行表达的言语能力。

Learning about language
知识课
Learning about languageLearning about language和课本一样，也分两部分：词法和句法。第一部分是词法训练，强化学生对本单元重点词汇、短语的掌握和使用；第二部分是句法训练，学习和使用英语“将来被动式”。
Period 1
Reading
阅读课
Warming Up以“谈论”、“学习”和“了解”的活动形式提供计算机背景知识，为其后的阅读作好词语、结构和心理的准备。教师还可补充“计算机的历史进程”：中国古代最早采用的一种计算工具叫筹策，又被叫做算筹。直到今天仍在使用的珠算盘，是中国古代计算工具领域中的另一项。明代时的珠算盘已经与现代的珠算盘几乎相同。
实际教学过程课时划分建议
Period 1
将Warming Up、Pre-reading、Reading和Comprehending整合在一起上一节“阅读课”。
Period 2
将Learning about language和Workbook中的USING WORDS AND EXPRESSIONS、USING STRUCTURES整合在一起上一节“语言知识课”。
