高中英语必修二Unit_3_Computers阅读课的教学设计及反思
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，采用了pair work, gr oup 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。
此外，学生的跨文化意识不高,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 opin ion, 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.(act ivity 1)2. Find and retell the grammar structure of the Present Perfect 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。

人教版高中英语必修2教案Unit3Computerunit 3 computerpart one: teaching design (第一部分：教学设计) period 1: a sample lesson plan for reading (who am i?) aims to talk about computer to read about computer procedures i. warming upwarming up by talking about computerlook at the pictures on page 17. what are they? what do they have in common? yes, they are computers. then what is a computer? a computer is a machine which stores knowledge in its memory and does calculations on that knowledge. 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 is purchased 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.computer jargon 计算机行话computer jargon means words to do with computers and surrounding topics. knowing what these words mean can help you know more about computers. some people use these words to impress other people (also known as buzzwords). examples of jargon: bit - the smallest data unit, can either be a “0.”or a “1.”. byte - unit of data. see also kilobyte, megabyte, gigabyte and nibble cpu –centralprocessing unit, another name for processor data - information stored on a computer disk -a place to store data. email -electronic mail. ghz -gigahertz. used often incorrectly to describe the speed of a processor. but with some 2.4 ghz processors faster than 3.6 ghz ones, it is clear that it is just a salesman trick. 共12页，当前第1页123456789101112load - get data from a disk nibble - half a byte save - put data on a disk ram –random-access memory(随机存取存储器), the more the better. usb -universal serial bus（通用串行总线，一种简化了插接多种附件的薄型插座）www - world wide web, part of the internet ii. pre-reading 1. questioning and answering‑‑‑what do you know about computer? ●electronic machine capable of performing calculations and other manipulations of various types 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. acomputer 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 automatically calculator: 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 computerconfigured in this way is give 2. 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 ubiquitous 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. 共12页，当前第2页123456789101112joining 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. reading 1. listening and reading to the recording of the text who am i?

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: 共12页，当前第5页123456789101112a robot that closely resembles a human a cyborg that closely resembles a human an artificially created, yet

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 authormathias 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

combination 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 processingchips 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 apple os for a macintosh, or windows 95 or windows 98 for a pc. there is also application software, like the games we play or the tools we use to compose 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 that they are ready for more input from you. this whole process is called booting up. the next step happens when you choose a program you want to use. you click on the icon or enter a command to start the program. let’s use the example 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 savedalready. 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 provided input to tell the computer what to do. the browser software determines 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. television 共12页，当前第7页123456789101112old portable television a 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 sat on the floor like furniture. newer tvs became smaller sothey could fit on shelves, 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 whole wall in your house, and may sit on the floor, or be just a large flat screen that can 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 web the 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. radio radio is a communications invention. though originally used to communicate between two people, it is now used to listen to music, news, and peopletalking. radio shows were the predecessor to tv programs. v. dvd dvd most commonly stands for

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. email email (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 is usually free. to send or receive an email, a computer with a modem and telephone line connected to the internet, and an email program are required. email addresses are generally formated like this: login@server.(com or fr or org or uk or other). 共12页，当前第8页123456789101112some companies

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 alsoused 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. section 3: words and expressions from unit 3 computers common n.

It is of the most effective ways of using words figuratively.Chronology means to describe things in order of time which is often used in recounting an event or describing the life of someone. It is an effective way to make a mass of things clear.An version:I, the computer, was a calculating machine in 1642 in France. Then I was built as an Analytical Machine, which was a technological revolution. I became a “universal machine” in 1936 to solve any mathematical problem. I was not very big at first then I became huge, the size of a large room before I was made smaller and smaller.I became clever and quicker and was connected with other computers and turned out to be part of a network in the early 1960s. I was brought into people`s, and many new applications have been found for me.Step 5 Closing down by spoken practiceTalk about the development of computers by answering the questions:1). Do you have your own computer at home?2). How familiar with computers do you think you are?3). How many times do you access the Internet newspaper in a week?4). How many times do you access the World Wide Web in a week?5). How many times do you send the e-mails in a week?6). How many hours do you spend in internet “chat” group in a week?7).

In general, what effects do you think the computer technology has on human societies and cultures?Step 6 Homework1. Go over the text, and try to learn all the useful words and expressions by heart2. Finish the exercises in comprehending on page 19.Artificial intelligence means man-made intelligence while “real intelligence”is the intelligence that human that human beings are born with. The term “artificial” includes all the calculations that a computer can do. It is different from human intelligence because it only works with electricity and can be turned off when the machine is unplugged fro the wall.Transistors are a way of sending and storing information that only take up a small space. They meant that computer could be made smaller and they led to computers becoming small and personal.A network is a number of computers that are joined together so that they all show the same program. So a number of students can work in the same room on the same program but at different computers.The Internet (WWW) is a worldwide information resource where people can do research, go shopping or sending messages to friends. When they send messages they do it by “e-mail” or “electronic mail”. The messages are sent by satellite to special place on the ground that can receive them. Them they are sent to the address where the person can open them and read them like a letter.The 1970s was when computers became small enough to come into people`s homes. These computers are called “personal computers”.The second period: Learning about important language pointsKnowledge aims:1.
