Unit 3 Computer 教学案Part One: Teaching Design (第一部分：教学设计)Period 1: A sample lesson plan for reading(WHO AM I？)AimsTo talk about computerTo read about computerProceduresI. 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 NibbleCPU –Central Processing Unit，Another name for processorData - Information stored on a computerDisk - 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.Load - Get data from a diskNibble - Half a ByteSave - Put data on a diskRAM – 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 InternetII. Pre-reading1. Questioning and answering---What do you know about computer？●Elect ronic 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 devi ce 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 programm able 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 au tomation 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 i s 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，i f 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.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 theexpressions in the text. Put them down into your notebook after class ashomework.Collocations from WHO AM I？begin as…，a calculating machine，be built as…，follow instructionsfrom…，sound simple，at the time，a technological revolution，write a book，make…work，solve problems，become huge，had artificial intelligence，go back to…，the size of…，go by，change size，become small and thin，get quick，stand there by oneself，be connected by…，share information by…，talk to…，bring…into…，deal with…，communicate with…，serve the human race3. 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.Chat (online)(在线)聊天To chat is to talk about ordinary things that are not very important. You can chat to one person or to many people. People also use this word now for parts of the Internet where we can talk with many different people at the same time. Usually，you chat on the internet in a chat roomor messaging service like AOL(American On-Line) Instant Messenger (AIM)，Yahoo Messenger，or MSN Messenger.4. Reading and transferringScan the text for information to complete the table below，describing the development of computer.In 1642In 1822In 1936In 1960sIn 1970sIV.

Reading aloud and discoveringNow go back to page 18 to read aloud and discover in the text examples of The Present Perfect Passive Voice.As the years have gone by，I have been made smaller and smaller.Since then，my family and I have been used by billions of people to deal with information with each other around the world by the Internet.V. Discovering useful structureWe shall do grammar exercises 1，2 and 3 on page 20.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.

Read the text Andy—The Android，underlining all the expressions and think of the fun you could have！Expressions from Andy—The Androidpart of a football team，once a year，get together，play a football game，be as…as…，in fat，look like...，on the football team，run fast，think like a human，shout to (i)computer language，have a good shot for a goal，get second place，win the first place，have a new kind of program，improve one’s intelligence，create a better system，play against a human team，in a way，program…with…，make up…，after all，with the help of…V. 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. The word derives from Greek Andr- ‘man，human’ and the suffix-eides used to mean ‘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.”Part Two: Teaching Resources (第二部分：教学资源)Section 1: A text structure analysis of WHO AM I？I. Type of writing and summary of WHO AM I？Type of writingThis is a piece of narrative writing.Main idea of the passage Beginning as just a calculating machine in 1642 inFrance，the computer has been experiencingimprovement again and over again over 300years ormore，which has not only made it more beautiful andintelligent but also changed man’s life a great deal！Topic sentence of 1stparagraphI began as a calculating machine in 1642 in France.Topic sentence of 2nd paragraphNo one could recognize me after I got my new transistors in the 1960s.II. A chain of events showing the development of computera calculatin g machine in 1642 in France → an Analytical Machine in 1822 → a “universal machine.” in 1936 → the size of a large room → made smaller and smaller → getting new transistors in 1960s→ clever and quicker → a network in the early 1960s → talking to humans using BASIC in the early 1960s → brought into people’s homes in 1970s → Internet III. A retold version of the text WHO AM I？I，the computer，was a calculating machine in 1642 in France. Then Iwas built as an Analytical Machine in 1822，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.Getting new transistors in 1960s I became clever and quicker. I was connected with other computers and turned out to part of a network in the early 1960s. Then I began talking to humans using BASIC in the early 1960s. In 1970s I was brought into people’s homes，and came the Internet.Section 2: Background information computersI. How Do Computers Work？Computer BasicsTo accomplish a task using a computer，you need a combination of hardware，software，and input.Hardware consists of devices，like the computer itself，the monitor，keyboard，printer，mouse and speakers. Inside yourcomputer there are more bits ofhardware，including themotherboard，where you wouldfind the main processing chipsthat make up the centralprocessing unit (CPU). Thehardware processes thecommands it receives from thesoftware，and performs tasks or calculations.Software is the name given to the programs that you install on the computer to performcertain types of activities. There is operating system software，such as theApple 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 weuse 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 devicesso that they are ready for more input from you. This whole process iscalled 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 usethe 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 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 haveprovided input to tell the computer what to do. The browsersoftware determines whether you have a printer attached to yourcomputer，and whether it is turned on. It may remind you to turnon 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 andsat on the floor like furniture. Newer TVs became smaller so they could fiton shelves，or even portable so you could take it with you wherever youwent. The smallest TVs can fit in your hand. The largest TVs can take up awhole 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 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 stan ds 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 distancesand is usually free. To send or receive an email，a computer with amodem and telephone line connected to the Internet，and an emailprogram are required. 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.Section 3: Words and expressions from Unit 3 Computerscommonn. 1. an area of grassland with no fences which all people are free to use or a piece of open land for recreational use in an urban area (常用于专有名词中): Every Saturday Jean went riding on the village common. Harlow Common is very beautiful in winter.哈洛公园在冬天时风景很美。

2019-2020年高中英语一轮复习 Unit 3 puters精品学案新人教版必修2 导读：我们已进入到了一个数码时代,高科技产品给我们的视听带来了震撼，也给当今的英语教学带来了革命性的改变，面对新形势，新问题，我们英语教师该如何面对呢？So what is the function of an English teacher in the digital age？The function of a English teacher in general is to municate to students the concepts and skills necessary to function well in situations which involve reading, writing, speaking, listening, and social skills. More and more English students worldwide will be able to interact with language teaching videos and virtual worlds which will bring them to a relatively high level of proficiency, especially since other people will be running around through these virtual worlds as well, talking to each other, getting help from each other, and practicing language functions in contextualsituations. This means that high quality puter language instruction will be free for anyone who has a fast enough Internet connection.My point in this article is that if you are an English teacher, you need to get more and more involved with puters in order to continue to improve your teaching skills. The following are my suggestions for English teachers in order to prepare themselves for the digital age (ranked in order of importance)：1. Get access to a puter with an Internet connection.2. Learn how to search for information on the World Wide Web.3. Learn how to send and receive E－mail.4. Learn how to join and participate in new groups, and find colleagues with similar interests.5. Learn how to attach documents and other files to E－mail.6. Learn how to create, publish, and update a home page.7. Learn how to type with both hands without looking at the keyboard.—From: english－teachers. htm请根据语义及提示写出单词1. I'm afraid we can't e, but thanks for the invitation ______ (无论如何)．2.

For example, puters have bee our good friends: with the help of puters, people all over the world are able to share whatever information on the net, which shortens the distance between them. With the invention of radio and TV, people now can stay at home to get themselves informed about both domestic and international news.But as a coin has two sides, technology can also have an negative influence upon people’s life. Now technology crimes are very mon. What’s more, the nuclear bomb threatens our human existence. So I think we must pay enough attention to the misuse of technology.In spite of its disadvantages, we should admit that technology is very useful. Without science and technology, man’s life would not be as convenient as today.Ⅱ. 按要求完成任务1. 写出文章中表示“任何事情都有两面性”的句子。
