2019-2020年高中英语人教版必修2 Unit 3 Computers period 1 教案

2019-2020年高中英语人教版必修2 Unit 3 Computers period1 教案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 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 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 othermetals. 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 hardware component that is controlled b y internally stored programs and that can perform substantial computations (including arithmetic andlogic 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 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 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?be gin as…, a calculating machine, be built as…, follow instructions from…, sound simple, at the time, a technological revolution, write a book, make…work, solveproblems, 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 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.

2019-2020学年高一上学期训练卷必修二 Unit3 Computers英语（二）（本卷满分100分）一、阅读理解（每小题2分，共16分）AWho is smarter? A human being or artificial intelligence(人工智能)?The question swept the world when a Google-developed program called AlphaGo defeated the world top player, South Korean Lee Se-del, 4-1.So, what comes next?Some people have been arguing that artificial intelligence, or AI in short, will be a bad thing for humans. In an interview with the BBC in 2014, UK scientist Stephen Hawking warned that “the development o f full artificial intelligence could mean the end of the human race.”So are we really about to live in the world shown in the Terminator movies? “Not quite ,” answered The Economist . After all, it’s not hard to get a computer program to remember and produce facts. What is hard is getting computers to use their knowledge in everyday situations.“We think that , for the human being, things like sight and balance(视觉平衡), are natural and ordinary in our life.” Thomas Edison ，founder of Motion Figures, a company that is bringing AI to boys, told the newspaper. “But for a robot , to walk up and down just like human beings requires various decisions to be made every second, and it’s really difficult to do.”As The Economist put it, “We have a long way to go before AI c an truly begin to be similar to the human brain, even though the technology can be great.” Meanwhile, John Markoff of The New York Times said that researchers should build artificial intelligence to make people more effective.“Our fate is in our own hands,” he wrote. “Since technology depends on the values of its creators, we can make human choices that use technology to improve the world.”1. What was the result of the match?A. Lee Se-del won AlphaGo 4-1.B. Lee Se-del was defeated.C. Google program beat AlphaGo.D. Neither side won the match.2. What does Thomas Edison possibly mean in his remarks? A. It’s very hard for AI to beat the human brain. B. AI would take the place of human beings. C. AI can make various decisions quickly. D. AI does better than humans in sight and balance.3. Who believes much has to be done to improve AI? A. Stephen Hawking. B. John Markoff. C. The New York Times .D. The Economist .4. What does the underlined part in the last paragraph imply? A. AI will improve the world completely. B. AI is in the control of human beings. C. AI may bring disasters to human beings. D. AI will make our future out of control. 【答案】1-4 BADB【解析】本文是一篇说明文，介绍了人工智能阿尔法狗击败了韩国棋手李世石，这引发了人们对于人工智能是否会超越人类的讨论。

What would say to a spoiled child who would not do his homework? Write a letter to the boy.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?II. A chain of events showing the development of computerIII. A retold version of the text WHO AM I?I, the computer, was a calculating machine in 1642 in France. ThenI was built as an Analytical Machine in 1822, which was a technologicalrevolution. I became a “universal machine” in 1936 to solve anymathematical 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 taskusing a computer, you need acombination of hardware,software, and input.Hardware consists ofdevices, like the computeritself, the monitor,keyboard, printer, mouse andspeakers. Inside your computer there are more bits of hardware, including the motherboard, where you would find the main processing chips that make up the central processing unit (CPU). The hardware processes the commands it receives from the software, and performs tasks or calculations.Software is the name given to the programs that you install on the computer to perform certain types of activities. There is operating systemsoftware, such as the Apple OS for a Macintosh, or Windows 95 orWindows 98 for a PC. There is also application software, like thegames we play or the tools we use to compose letters or do mathproblems.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 devices so thatthey are ready for more input from you. This whole process iscalled booting up.The next step happens when you choose a program you wantto use. You click on the icon or enter a command to start theprogram. Let’s use the example of an Internet browser. Oncethe program has started, it is ready for your instructions.You either enter an address (called a URL, which stands forUniform 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 theprinter icon. Again, you have provided input to tell thecomputer what to do. The browser software determines whetheryou have a printer attached to your computer, and whether itis turned on. It may remind you to turn on the printer, thensend the information about the web page from your computer overthe 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 woodenframes and sat on the floor like furniture. Newer TVs becamesmaller so they could fit on shelves, or even portable so you couldtake it with you wherever you went. The smallest TVs can fit in your hand. The largest TVs can take up a whole 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 to communicate between two people, it is now used to listen to music,news, and people talking. Radio shows were the predecessor to TVprograms.V. DVDDVD most commonly stands for “digital versatile disk”.It can play video that is of a higher quality than a VHS tape.VI. Two kinds of DVDThey can also hold 4.7 GB of information as opposedto the 700 MB that a CD can hold. A plus of using a DVDfor a video is the ability to have interactive menus andbonus features such as deleted scenes and commentaries.VII. EmailEmail (electronic mail) is a message, usually text, sentfrom one Internet user to another. Email is quicker than snail mail(mail) when sending over long distances and is usually free. To send or receive an email, a computer with a modem and telephone line connected to the Internet, and an email program 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。

Unit 3 Computers language points课时作业（本卷满分100分）一、阅读理解（每小题2分，共16分）AWho is smarter? A human being or artificial intelligence(人工智能)?The question swept the world when a Google-developed program called AlphaGo defeated the world top player, South Korean Lee Se-del, 4-1.So, what comes next?Some people have been arguing that artificial intelligence, or AI in short, will be a bad thing for humans. In an interview with the BBC in 2014, UK scientist Stephen Hawking warned that “the development of full artificia l intelligence could mean the end of the human race.”So are we really about to live in the world shown in the Terminator movies?“Not quite,” answered The Economist. After all, it’s not hard to get a computer program to remember and produce facts. What is hard is getting computers to use their knowledge in everyday situations.“We think that, for the human being, things like sight and balance(视觉平衡), are natural and ordinary in our life.” Thomas Edison，founder of Motion Figures, a company that is bringing AI to boys, told the newspaper. “But for a robot, to walk up and down just like human beings requires various decisions to be made every second, and it’s really difficult to do.”As The Economist put it, “We have a long way to go before AI can truly begin t o be similar to the human brain, even though the technology can be great.”Meanwhile, John Markoff of The New York Times said that researchers should build artificial intelligence to make people more effective.“Our fate is in our own hands,” he wrote. “Si nce technology depends on the values of its creators, we can make human choices that use technology to improve the world.”1. What was the result of the match?A. Lee Se-del won AlphaGo 4-1.B. Lee Se-del was defeated.C. Google program beat AlphaGo.D. Neither side won the match.2. What does Thomas Edison possibly mean in his remarks?A. It’s very hard for AI to beat the human brain.B. AI would take the place of human beings.C. AI can make various decisions quickly.D. AI does better than humans in sight and balance.3. Who believes much has to be done to improve AI?A. Stephen Hawking.B. John Markoff.C. The New York Times.D. The Economist.4. What does the underlined part in the last paragraph imply?A. AI will improve the world completely.B. AI is in the control of human beings.C. AI may bring disasters to human beings.D. AI will make our future out of control.BAs life in cities worldwide becomes more expensive, urban designers are using modern technology to help citizens avoid traffic jams, and shorten the time needed for bus waiting and other things. Technology is also used to cut costly waste.In Santander, a Spanish port city, parking is easy to find. As one car drives away, an underground sensor shows that a parking space is now free. 400 sensors send messages to signs on streets, and GPS devices direct drivers to the nearest available parking spaces, reducing traffic jams. Trash is collected only when the bins are full and bus stop signs show exactly when the next bus is coming. The public parks are watered only the soil gets dry. All this is made possible by 20,000 sensors installed on buildings, street posts andeven buses. They are part of the “smart city” project, launched by the University of Cantabria seven years ago.University researchers like Luis Munoz regularly meet with locals to discuss how to make their city even smarter. “They propose when they have ideas and sometimes even develop by themselves. Here, we give them the opportunity to see these ideas happen in real life,” said Mu noz. For example, the university helped a woman create an app that outlines the easiest route for walking with a baby stroller. Another provides information to residents about their water consumption and sends an alarm to their phone if there is a leak.The Santander smart project is attracting the attention of larger cities in Europe and elsewhere that are looking for smart solutions to urban problems.5. What is the life like in Santander?A. It is meaningful.B. It is full of freedom.C. It is likely to change fast.D. It is effective and convenient.6. How can residents help Munoz’s job?A. By offering some original or fresh ideas.B. By showing him around the city.C. By installing sensors themselves.D. By using as little water as possible.7. What doe s the underlined word “Another” in Paragraph 3 refer to?A. A university.B. A phone.C. An easy route.D. An app.8. What can be the best title for the text?A. A Worldwide ProblemB. A Smart City ProjectC. A Creative ResearcherD. A Trend in Urban Design二、七选五（每小题2分，共10分）There have been a lot of comments recently surrounding 5G, the next generation of wireless technology. 9. ? How might it change our lives?5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity (容量). 10. . It is expected to permit more users to do more things at a faster rate.However, technology experts say there is a major way that 5G is different from the earlier systems. 11. . It will affect many more devices and industries than other “G” versions.5G will help fuel future “smart cities” by connecting sensor networks. 5G is also expected to connect self-driving cars and support new technologies involving virtual reality(虚拟现实). Higher 5G speeds could also permit doctors to commonly perform remote medical operations. Factories and businesses could use 5G technology to increase automation and improve the collection of information.12. . The increased data flow across 5G networks would give Internet attackersa lot more possibilities to steal and misuse data. In addition, the wider use of a 5G wireless network means any breakdown of the system would have more widespread and severe results. Such difficulties could affect public safety. 13. , or a network breakdown could cause self-driving vehicles to crash.A. Why is 5G so popularB. What is this technologyC. Every coin has two sidesD. The new 5G system promises more of the sameE. It will move beyond mobile network technologyF. A breakdown of 5G networks may cause economic lossesG. A failure during a doctor’s remote operation could lead to death三、完形填空（每小题1.5分，共30分）Crowdsourcing is an interesting new application of the saying “Many hands make light work”. In the sa me way that classmates might work 14 on a task, now dozens, hundreds or thousands of people can collaborate(合作) on projects that would be too ___15 or complex for a small group of co-workers. At the same time, crowdsourcing follows the old 16 that two heads are better than one. When many people collaborate, they not only work faster, but they also work better, by 17 their intelligence and experience.Perhaps one of the most 18 examples of crowdsourcing is Wikipedia —an online encyclopedia(百科全书) that is 19 , edited and managed by people all over the world. The writers are volunteers who 20 their work for free. And 21__ them, Wikipedia now offers more than 4 million free articles in English, and millions more in almost 300 other 22 .

2019-2020学年度人教版必修二Unit3 Computers-Period1 Reading教案(WHO AM I?)IntroductionIn this period, after the warming up,students will first be guided tounderstand how computer works. Thenthey will be helped to read a narrationabout computer and its development.Three examples of “Warming up” designs are presented for the teachers’ reference. Computer and overhead projector may be used to aid the teaching and learning.Objectives■To help students learn to make decisions and to reason in English■To help students learn to read an introduction about computer■To help students better understand “the computer science”■To help students learn to use some important words and expressions■To help students identify examples of “the present perfect passive voice” in the textFocusAidsMultimedia facilities, tape-recorder, photos, diagramsProcedures1. Warming up⑴ 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?⑵ Warming up by learning some computer jargonsJargons are terms used by some special people. These are some of the computer jargons.⑶ Warming up by getting to know what a computer virus is. Computer viruses (病毒)are small software programs that are planned to spread from one computer to another and to do harm to computer operation.A virus might harm or wipe out data on your computer, using your e-mail program to spread itself to other computers.Viruses are most easily spread by e-mail messages. That is why it is important that you never open e-mail unless you know who it's from and you are expecting it.Viruses can be made to look like funny images, greeting cards, or audio and video files.Viruses also spread through downloads on the Internet. They can be hidden in software or other files or programs you might download.To help avoid viruses, it's essential that you have the latest updates and antivirus tools, stay informed about recent threats, and that you follow a few basic rules when you surf the Internet, download files, andopen attachments.2. Pre-reading by talking about how computer worksHow does a computer work?A computer has four main parts: the arithmetic and logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by groups of wires.The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were comprised of many separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.3. 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.4. Reading aloud and underlining expressionsNow we are to read the text once again and underline the expressions in the text. Jot them down into your notebook after class as homework.5. Reading and transferringScan the text for information to complete the flow chart below, describingthe development of computer. →→→→→→→→→ 6. Reading to get the general idea of theType of writing and summary of WHO AM I?7. Retelling the textTry to retell the text in your own words with the help of the flow chart or “the Type of writing and summary of WHO AM I?” above.8. Closing down by doing a quiz。
