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. Underline them and study carefully.Show the following on the screen/board:●Over time my memory has developed so much that, like an elephant, I never forgetanything I have been told!●And my memory became so large that even I couldn’t believe it!Help students sum up the form and function of this structure:Form:so + adj./adv. + that + clauseFunction:This structure is used when emphasizing the degree or amount of something by saying what the result is.Step IV DiscussionT: Discuss this question in groups: Why do many countries want to host the Olympic Games while others do not? 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.。

人教版英语高中必修二Unit 3 Computers part1 教案Unit 3 Computers 教案1（WHO AM I?<PART 1>)IntroductionIn this period, after the warming up, students will first be guided to imagine and share their views about the technology. They will then be helped to read a narration entitled WHO AM I. Examples of “Warming Up” designs are presented in this book for teachers’ reference. Computer and overhead projector may be used to aid the teaching and learning.ObjectivesTo talk about computerTo read about computerFocusWords simplify, sum, operator, logically, solve, reality, personal, network,finance, applications, exploreExpress ions technological revolution, artificial intelligence, as a result, anyhowThe boot device contain s 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 themwithin 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 Internet II. Pre-reading1. Questioning and answering---What do you know about computer?(1) 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. (2) A multi-function electronic device that can execute instructions to perform a task.(3) A device that accepts information, processesit, and supplies an output. A computer usually contains memory, a control unit, arithmetic and logical units, and a means for input and output.(4) 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.(5) 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. (6) A machine for performing calculations automatically calculator: an expert at calculation (or at operating calculating machines)(7) A computer is a device or machine for making calculations or controlling operations that are expressible in numerical or logicalterms. 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 ourlives 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.

Suppose one is a journalist and the other is a computer, the journalist is interviewing the computer.Step 5 Learning personification and chronologyPersonification means to treat something as if it were human or had human qualities. 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). Do you think the commercial services on the net are reliable?8). In general, how positive or negative an experience is it for you to work with computers?9). In general, what effects do you think the computer technology has had on your study?10). 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 itonly 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. Get students to learn and grasp the important useful new words and expressions: calculating, calculator, PC, laptop, common, simplify, simple-minded, artificial intelligence, anyhow, totally, network, truly, race, birth, go by, deal with, human race2. Important useful sentence patterns:1) I began as a calculating machine in France in 1642.2) As time went by, I was made smaller and smaller.3)And my memory became so large that even I couldn`t believe it.3.
