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.
