新课标高中英语必修2 Unit 3 Computer 全单元教案M2 Unit 3 ComputerPeriod 1:Warmin/g up(WHO AM I?)Warming upThis section is an introduction to the topic．It is to get the students thinking about the different ways computers can be made．Do this part of the lesson in pairs and as a speaking activity．Warming 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.Draw on the blackboard a diagram to illustrate the influence of the computer and the Internet over the school education．Below is a diagram you may like to use．Ask students to look at the diagram and consider, ”What changes have computers and the Internet brought to schools? What changes will they bring to schools in the future?”Ask the Ss to work in groups and to make a list of the possible changes they can think of．When most of the groups have their lists ready, the teacher can hold a class discussion．Write down the major changes the students think of under / beside the diagram．The teacher can add one or two changes that may affect their own teaching．For example, “Computers and the Internet can help busy parents contact teachers by email．”The teacher can end the task with a brief s ummary, or hold a further discussion to find out students' personal opinions about the changes．For example, ask them, “Do you like all these changes? Why and why not? What changes do you like / dislike?”Some information: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 InternetPeriod2-3 Pre-reading & ReadingPre-readingThis can be a continuation of the Warming Up．Let the students discuss the questions set out in the Student's Book．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. A computer usually contains memory, a control unit, arithmetic and logical units, and a means for input and output.●a programmable har dware 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 performi ng 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 ubiquitous as the telephone itself. They’re a much more use ful 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.II. ReadingThis is the purpose of the reading and so it is important that the students learn to use all the clues in the text to help them understand the gist of what they are reading．So encourage them to look at the pictures and the heading and guess what the text might be about．Then ask the class to read the passage silently．Make sure the students have the chronology of the development of computers in their minds．Ask them:1. 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…, follow instructions from…, sound simple, at the time, a technological revolution, write a book, make…work, solve problems, become huge, had artificial intelligence, go back t o…, 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 room or messaging service like AOL(American On-Line) Instant Messenger (AIM), Yahoo Messenger, or MSN Messenger.IV. Closing down by doing comprehending exercisesTurn to page 18 and in pairs do the comprehending exercises No. 1 and 2.

人教版高中英语必修2 Unit 3 Computers第一课时教案

人教版高中英语必修2 Unit 3 Computers第一课时教案Period One Intensive ReadingTeaching Goals：1. Target Languagea. The Key Words and Phrasessimplify logically technological revolution solve from…on personalas a result totally so…that network Web application explore anyhow human raceb. T he Key SentencesOver time my memory has developed so much that, like an elephant, I never forget anything I have been told!And my memory became so large that even I couldn’t believe it!2. Ability Goals：Enable students to learn about the development and history of computers.Teaching Important & Difficult Points：Understand how details are used to support topic sentences.Teaching Methods:Prediction, scanning and discussion.Teaching Procedures & WaysStep I Warming-upT: How many of you have computers in your home? Please put up your hands.Ss :respond accordingly.T: What do you usually do on your computers?Ss:Type documents/homework, listen to music, watch videos, play games, search on the Internet, send mails …T: When I were at your age, I knew nothing about computers. Most Chinese families never heard about it. However, in recent years, computers have become more and more popular, and most families in cities have one or more than one computer in their home. And some families in villages also have their own computers. Computers make life more convenient and colorful. However, it took a long time for humans to have computers that we see today. Now look at the pictures on page 17 and discuss what they have in common. Then think about Questions 2 & 3.Suggested answers:1.These pictures are all technological inventions.2.From these pictures, we know computers have experienced a long development process,and the development will never stop.3.(There may be various answers.)Step II Pre-readingPrediction: Let students predict the content of the passage according to the pictures and the title. This will involve students in active thinking and exploring.Then let them make a list of the ways computers are used today.Sample list: date processing; industrial design; learning and teaching aids; TV program editing; entertainment (watch TV/video, listen to music, play games, online chat…) communication (e-mail, e-card, instant message) …T: Now look at the inventions in activity 3. First check their meanings in your dictionaries. Then put them in the order according to the time when they appeared.Help students understand the meanings of the words: analytical, calculate and universal. Note:Universal machine is also known as Alan Turing's “universal computing machine”, is capable of computing any algorithm.Students may have different answers. They will check it after reading the passage.T: Have you put them in the right order? You will find it after reading the passage. Now turn to page 18 please.Step III ReadingSkimmingGet students read the whole passage and try to get the main idea of it.After readingT: What does “I” in the title refer to?Ss: Computer.T: What is the main idea of the passage?Ss: The passage is mainly about the history and development of computers.ScanningT: Correct! Now read the passage and finish the timeline. With this timeline, you will have a clear idea of the development of computer.Check the answers.T: The passage has three paragraphs. Find out the topic sentence of each paragraph, and the details that are used to support the topic sentences. Then complete the chart in activity 2.the topic sentences are not standing there alone, they are supported with details and date, which make the topic sentences more convincing. Now I will play the tape of this passage. Listen and find out/underline the difficult words and expressions.Teacher gives some explanations.T: What can be “over time” replaced by?Ss: As time goes by.T: How do you understand the word “simplify”? Look! (on the board: simple+-ify). -ify is a suffix which means to turn into, make or become. For example, beautify. So if you know the meaning of “simple”, you can easily get the meaning of “simplify”. Who can tell me its meaning?S: To make something easier or less complicated.T: What does “it” in line 9 refer to?Ss: It refers to the fact that computer was programmed by an operator who used cards with holes.T: Why was Alan Turing called computer’s real father?S: I guess that’s because Alan made computer more powerful, which could solve any difficult mathematical problem.T: What does “this reality” in line 15 refer to?S: It refers to the reality that computer had grown as large as a room.T: In paragraph two, there are two sentences which contain the use of “so…that…” structure.

Use the mind map below to help you. Then prepare for a class discussion. Put forward your ideas and give reasons for your choices.T: Why do many countries want to host the Olympic Games?S: Hosting the games has a major effect on the economy and brings international prestige to the country. Thousands and thousands of visitors come to the game s and the host cities are permanently improved. By planting trees and creating parks, the city becomes more attractive for tourists.S: It helps to strengthen the spirit of patriotism and also can create more job opportunities and improve the quality of employment.S: The Olympic Games is the world's largest and highest level, and most widely influential sports event. The people of all countries enhance mutual understanding and friendship and safeguarding peace in the world event. Besides, the hosting of the Olympic Games is not only a country's comprehensive strength of the comprehensive test, but also to expand a country’ influence around the world, and at the same time promote their own development as a good opportunity.T: Well done! Why do many countries don’t want to host the Olympic Games?S: Preparing for the Olympics Games is a huge undertaking. Just like the athletes, the host city spends years getting ready for the event. Before deciding which city will host the Olympic Games, the International Olympic Committee (IOC) has to examine bids from allover the world. Bidding for the games begins about ten years in advance. Without preparing a very strong bid1, a city will not win the competition to host the games.S: Hosting the Olympic Games take so long time and so much money to prepare. Building the infrastructure costs huge amounts of money. Holding the World Cup in 2002 in Japan and South Korea, for example, meant that ten new stadiums had to be built, as well as many hotels and an improved transport system. In Beijing, after winning the bid, the government began major construction projects — the extension of the underground, the improvement of the airport and the building of new motorways. Each host city must also build an Olympic village for the athletes.S: Too many visitors may do harm to the environment of the city, in addition, the venues and buildings may be wasted after the Olympic Games.T: Well done! As every coin has two sides, hosting the Olympic Games has its advantages and disadvantages. For our powerful China, it is a good opportunity to host the Olympic Games which can benefit us a lot.Step V Homework (retelling)T: Suppose you work for an information technology magazine. Write a short passage which briefly introduces the history and development of computers. Don’t write in the first person.。

Period 3: Using Language(ANDY— THE ANDROID)AimsTo discuss about ITTo write a report about ITTo read about androids or robotsThe purpose of this exercise is to encourage students to listen and then use what they have heard to help them fill in a chart about computers．It is an important exercise because it links skills together and uses them to produce a useful piece of writing．Make sure the students look at the chart before they listen to the tape．This is to sharpen their attention and listen for the answers．This will also help them get the gist of the text．When filling in the chart, the students will have to use their own experience as well as information from the listening text．ProceduresI. Warming up by talking about ITWhat is Information technology?Information technology (IT) or information and communication technology (ICT) is the technology required for information processing. In particular the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information from anywhere, anytime.II. Listening and writingTurn to page 21. Look at the pictures and listen to a conversation about different kinds of information technology or IT, discuss and write down in groups the advantages and disadvantages of each kind.III. Speaking and writingThe purpose of this exercise is to discuss together and then decide which kind of computer you would like to buy for your school．Think about what the school needs as well as what you like．Let the students do the exercise in pairs and share theirideas with others．Finally they should write the report．Remember to say which computer you have chosen and give a reason．You should also say why you did not choose the other computers．Suppose 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. Reading, underlining and speakingThis is a speaking activity about designing an android．The purpose of the activity is not the design but the quality of the discussion．So try to make sure each pair makes a contribution to the finished design．Then let them discuss their ideas with another pair．Perhaps that will give each pair some more ideas for their android．Finally let students share their ideas with the class．It 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!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…, in 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 letterThe purpose of this piece of writing is to develop empathy in the students．They have to imagine they are androids looking after a family with one child．They need to imagine what problems and delights this android might have to deal with．Putting yourself in someone else's shoes is a very important way of understanding how other people feel．This is a very useful exercise．T: Suppose 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 ganoid 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 human Although 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 wo rk 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.” Sample writing:Hello everybody, my name is Liu Yan．I am a 321 model android．I work for the Li family and I look after their library．My job is to store all the books that they borrow from their school or friends in my brain．Of course my brain is as large as a mountain so work like that is no trouble to me．I really eat books just like people eat food．The Lis have a child who needs me to remember all his school textbooks so I can do his homework for him．He just gives me the information on the subject, what has to be done and the page numbers and I get on with it while he enjoys himself with his friends．Sometimes I don't think it is right to do his homework for him — it's somewhat cheating. However, his parents are very concerned at the pressure of work in school these days．The child has too much homework to do. They like him to go to the key school but they also want him to be able to have hobbies, learn to swim and keep fit! Poor child!Mr. and Mrs Li work very hard too．Mr. Li is an architect and designs great tall apartment blocks．Mrs Li is a doctor and has to look after many patients．I remember all the plans for Mr. Li's projects and can tell Mrs Li which drugs are the best to give any particular patient．Mrs Li no longer has to read all those medical journals because I can do it for her．She and Mr. Li can have some time together to enjoy life too．So they consider me the most important person in the family after themselves．I am always introduced to their friends and play with visiting children．I am the perfect family academic aid and, although I was not cheap to buy, Mr. Li says I was worth every yuan!品味人生1、不管鸟的翅膀多么完美，如果不凭借空气，鸟就永远飞不到高空。
