高一英语 M2 Unit3 ComputerPeriod 1:Warming 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 showresults. 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 sc hools 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 taskwith a brief summary, 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 d evice 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 electronicdevice. 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 isclear 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 & Reading Pre-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 performingcalculations 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 hardware component that is controlled by internally stored programs and that can perform substantial computations (including arithmetic and logic operations) without humanintervention. 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 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.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 expressions Now 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 to…, the size of…, go by, chan ge 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.

高中英语_Module2Unit3 computers教学设计学情分析教材分析课后反思
本单元为科技类说明文，为高考阅读理解重要题材。
在高考中占有重要地位。
本堂课是阅读课，为了训练和提高学生的阅读技能，在教学过程中采用任务型语言教学法。
采取的任务由浅入深，由易到难，步步推进从而实现学生阅读的目的。
本节课以任务推动学习，以任务贯穿学习。
课堂活动由听、说、读、写4种语言展现形式组成一个个小任务，形成任务串，前后环环相扣，达到理解课文、用自己的语言重新诠释课文的目的。
学生对电脑并不陌生，日常中也经常接触电脑，因此此话题为学生熟悉话题，阅读上不会有太大障碍。
学生整体英语水平不是太高，因此会导致阅读中出现卡壳现象，阅读设计的难度不要太大，同时再设计中要考虑给学生帮助。
如小组合作可以帮助学生解决大部分困难。
文本中出现的专业术语较多，因此需要学生提前预习充分。
小组内差异较大，需要在教学中予以指导。
1. Put them in an order according to the time.( ) analytical machine ( ) laptop ( ) calculating machine( ) robot ( ) PC ( ) universal machine 2. Fill in the cloze:今天听了当老师的一节课，必修二unit3 computers。
上课环节流畅，内容衔接得当。
导入采用生活中的事物和常见的缩略语，如WWW,PC,IT，telephone，washing machine等，一下子调动了学生的积极性和兴趣。
虽然当今电脑很常见，但是这些词的完整形式却并非人人都会。
此意调动了学生的积极性，一下子拉近了课堂的距离。
接下来的阅读采用渐进式阅读教学策略，通过快速阅读，获取文章的基本信息点，让学生有一个大概的了解，为下一步细节阅读中的迅速定位打下了基础。
通过讨论的方式让学生交换思想，既避免了阅读课的枯燥，又能锻炼学生的交流能力，同时对于基础较弱的学生来说也是一个促进。

【人教版】高中英语必修二：Unit 3 Computers 教案
Unit 3 Computers I. 单元教学目标II. 目标语言III. 教材分析与教材重组1. 教材分析本单元以computers为话题，旨在通过单元教学，综合听、说、读、写等多种形式，使学生了解计算机和信息技术的产生和发展过程及其在我们的学习、工作、娱乐等生活中所起的重要作用，激发学生对信息技术的兴趣。
1.1 Warming up提供几幅与计算机有关的图片，形象地说明了计算机的发展历程，并用三个问题引发学生对这一话题的思考，从而起到热身的作用。
1.2 Pre-reading根据文章内容预设问题，检查学生对computers相关知识及应用的了解。
学生对computers的了解可能参差不齐，这更能激发学生想获取更多知识的欲望，从而引出下面的阅读文章——WHO AM I?。
1.3 Reading中以别致的标题WHO AM I?引起学生的好奇心，使学生迫不急待地阅读这篇文章，并判断出“I”是computer，从而对文章的内容印象更深刻。
文章以第一人称的形式按时间先后顺序讲述了computers的产生、发展和现状，并用拟人化的口吻表达了computers乐于为人类服务的精神。
1.4 Comprehending 1 通过scanning的方式完成反映计算机发展历程的时间进程；2 通过填表的形式帮助学生宏观梳理文章结构，找出每个段落的主题句（论点）及具体的支持性论据；3 是读后讨论，要求学生结合自己的生活实际讨论计算机如何改变了我们的生活。
1.5 Learning about language分词汇（Discovering useful words and expressions）和语法（Discovering useful structures）两大部分。
Discovering useful words and expressions 1 根据单词释义写出相对应的词汇，考查学生对WHO AM I? 文章中的重要词汇及短语的理解。
