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 . That’s an amazing achievement for a project that ___23 started in 2001.Traditional institutions, such as London’s Tate Museum, have also 24__ Crowdsourcing for projects.

Part One: Teaching Design (第一部分：教学设计)Period 1: A sample lesson plan for reading(WHO AM I?)AimsTo talk about puterTo read about puterProceduresI. Warming upWarming up by talking about puterLook at the pictures on page 17. What are they? What do they have in mon? Yes, they are puters. Then what is a puter?A puter 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 puter usually has a monitor to show results. However, some puters can speak; these puters can be used for voice mail.计算机室A puter frequently requires a boot device. The boot device contains the puter’s operating system and data. puter programs can be installed onto a puter. Some people think that puters are less useful if they do not have access to the Internet. They think this because the Internet allows the puters to send and receive data and email across the world.曙光3000巨型计算机A puter is now almost always an electronic device. It usually contains materials which are toxic; these materials will bee toxic waste when disposed of. When a new puter 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 puters 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.puters bee obsolete quickly. Very often they are given away and new ones replace them within two or three years. This makes the problem worse. puter recycling is thus mon. Many projects try to send working puters to developing nations so they can be re-used and will not bee waste as quickly.II. Pre-reading1. Questioning and answering---What do you know about puter?●Electronic machine capable of performing calculations and othermanipulations 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, puters are called mainframes, miniputers, and microputers. Microputers include desk-top and portable personal puters.●A multi-function electronic device that can execute instructions to performa task.●A device that accepts information, processes it, and supplies an output. Aputer usually contains memory, a control unit, arithmetic and logical units, and a means for input and output.●a programmable hardware ponent that is controlled by internally stored programs and that can perform substantial putations (including arithmetic and logic operations) without human intervention. A puter 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 monly classes most puter-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 puter is a device or machine for making calculations or controlling operations that are expressible in numerical or logical terms. puters are constructed from ponents that perform simple well-defined functions. The plex interactions of these ponents endow puters with the ability to process information. If correctly configured (usually by, programming) a puter can be made to represent some aspect of a problem or part of a system. If a puter configured in this way is give2. Discussing and sharing---How have puters changed our lives?Someday soon, if you haven’t already, you’re likely to plug into the puter network nation growing in our midst. puter terminals, or small puters connected via modem (a modulator/demodulator circuit for encoding/decoding puter 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 puter network is the same as joining a munity. Small systems are like villages, where new members are formally weled. The larger networks, the Source and puServe, for example, are cities-anonymous, full of life and events, but difficult to fit into.III. Reading1. 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 allthe expressions in the text. Put them down into your notebookafter class as homework.size, bee smalland thin, get quick, stand there by oneself, be connected by…, share information3. 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 andScan the text for information to plete the table below, describing the developmentof puter.Turn to page 18 and in pairs do the prehending exercises No. 1 and 2.Period 2: A sample lesson plan for Learning about Language(The Present Perfect Passive Voice)AimsTo learn to useThe Present Perfect Passive VoiceTo discover useful words and expressionTo discover useful structuresProceduresI. Warming up by reading to the tapeTo begin with, turn to page 18, listening to and reading to the recording of the text WHO AM I?

Reading aloud and discoveringNow go back to page 18 to read aloud and discover in the text examples of The Present Perfect Passive Voice.V. Discovering useful structureWe shall do grammar exercises 1, 2 and 3 on page 20.VI. Closing down by doing a quizCorrect the mistakes in these passive voice sentencesExample: The house was build in 1880. (correct = The house was built in 1880.)1. 3000 employees were laying off.2. A story will made up.3. An idea was putted forward for discussion.4. Has the book been give back to you yet?5. My bank loan will be payed off in five years time.6. Nothing can be hold against me.7.

The old cinema is being pull down.17. The protesters being held back by the police.18. The road was blocking off.19. Thirty more people were laid off last week.20. Your jacket can be hanged up over there.Period 3: A sample lesson plan for Using Language(ANDY— THE ANDROID)AimsTo discuss about ITTo write a report about ITTo read about androids or robotsProceduresI. Warming up by talking about ITWhat is Information technology?Information technology (IT) or information and munication technology (ICT) is the technology required for information processing. In particular the use of electronic puters and puter 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 writingSuppose you and your partner are going to help choose puters for your school. Now talk about the special things each of the puter can do and write a report to your headmaster.IV. Reading, underlining and speakingIt is said that puters 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!Suppose you are an android. 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 puterIII. A retold version of the text WHO AM I?I, the puter, 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 puters 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 putersI. How Do puters Work?puter BasicsTo acplish a task using a puter, you need a bination of hardware, software, and input.Hardware consists of devices, like the puter itself, the monitor, keyboard, printer, mouse and speakers. Insideyour puter there are morebits of hardware, includingthe motherboard, where youwould find the mainprocessing chips that make upthe central processing unit(CPU). The hardwareprocesses the mands itreceives from the software,and performs tasks or calculations.Software is the name given to the programs that you install on the puter to perform certain types of activities. There is operating system software,such as the Apple OS for a Macintosh, or Windows 95 or Windows 98for a PC. There is also application software, like the games we playor the tools we use to pose letters or do math problems.You provide the input. When you type a mand or click on an icon, you are telling the puter what to do. That is called input.How They Work TogetherFirst, you provide input when you turn on the puter. Then the system software tells the CPU to start up certain programs and to turn on some hardware devices so that theyare ready for more input from you. This whole process is calledbooting up.The next step happens when you choose a program you wantto use. You click on the icon or enter a mand 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 puter 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 puter to send the information from the web page over the phone wire or cable to your puter. 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 the puterwhat to do. The browser software determines whether you havea printer attached to your puter, and whether it is turned on.It may remind you to turn on the printer, then send theinformation about the web page from your puter over the cableto 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” es 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 inyour 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 canbe mounted on the wall. Many TVs are now made in wide screen shapelike 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 puters 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 puter network exists - such as Wikipedia on CD. In this case no real physical site exists other than the place where the puter is. Blog and Wiki capabilities will also not be available because these require a munication with other puters.IV. RadioRadio is a munications invention. Though originally used to municate between two people, it is now used to listen to music, news,and people talking. Radio shows were the predecessor to TV programs.V. DVDDVD most mon ly 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 mentaries.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 puter 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.( or fr or org or uk or other).Some panies 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 mon 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 putersmonn. 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 mon.

Unit 3Computers(时间：100分钟分值：120分)第一部分阅读理解(共两节，满分35分)第一节(共10小题；每小题2.5分，满分25分)AWhen third and fourth graders in Cheryl Barber's class at Helena Flats Montessori School write stories about plants, they're not using pencils and paper, but rather iPads to take photos and type text.Nine-year-old Jenna Oilar held an iPad up to a bamboo plant.At the touch of the screen she took a photo.With her index finger and thumb she then changed it to fit a page in her group's book.Under the photo she typed in text.Students can use many free apps(应用程序), uploaded by their teacher, to help learning.The apps offer a wide educational games suitable for learning.To teach fluently, Barber plans to have students record themselves' reading.There are also advantages in using tablets with students who have disabilities or are learning a second language.Students can enlarge text, change fonts(字体), translate text to a different language or use audio to read text.Using mobile technology isn't new to Barber's classroom.Before the iPads, her students used laptops and the iPod touch.The apps don't work to students who are learning to count money, tell time, solve maths problems and spell as they will get immediate feedback if they are doing a problem incorrectly.Rather than traditional flashcards, Alex Puhl, 8, enjoys playing the game “Math Ninja” where he fights a robotic army by solving maths problems that pop up on the screen.Students can only use games loaded by their teachers.The iPads also show a user's history—when a student starts or stops a program.Student scores are e-mailed directly to Barber.Is third grade too early to introduce so much technology? Barber doesn't think so.“By 2015, third grade is expected to type a story all in one setting，” Barber s aid.What hasn't changed is that teachers still teach required curriculum(课程)．There still are pencils at desks, notebook paper, and yes, teachers' lectures and worksheets to fill out by hand.1．What can we conclude from the passage?A．The iPad is a real game changer in class.B．The iPad has side effects on students.C．The iPad brings convenience to teachers.D．The iPad is the cause of students' failure.2．What did Jenna Oilar do with an iPad?A．She was texting a message for her teacher.B．She was playing a computer game attentively.C．She was taking a picture of a bamboo plant.D．She was typing a letter to her parents.3．The benefits of iPads for students are that ________．A．they are free and programmed with funny gamesB．they are also suitable for children with disabilitiesC．they are timely uploaded by the school teachersD．they are only intended for learning languagesBComputer technology is still developing rapidly.The computer of the future will increase in value and performance while decrease in cost.It will become smaller, but faster and more powerful.It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now.A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years.Two of the most interesting areas of computing that are currently being developed are quantum computing(量子计算) and nanotechnology(纳米技术)．Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today.Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many statistics at the same time.Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size.These computers could be incorporated(并入) into everyday objects, including electrical appliances(电器), clothes and even the human body.We will beable to use computers in new and unimaginable ways.They will become a part of our lives rather than simply being a box that is used only for specific purposes such as work.Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy better health and happier lives.4．According to the text, quantum computing ________．A．has been put in use so farB．can make computers run by themselvesC．can reduce the cost of computersD．will work by using transistors5．The text is mainly about ________．A．what nanotechnology isB．what quantum computing isC．what the computer of the future is likeD．what future computers can bring us6．Which of the following best shows the structure of the text?(①＝Paragraph 1, ②＝Paragraph 2，…⑤＝Paragraph 5)A. B.D.CAlmost every day, we discuss the topic of health, especially for kids.But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight.Let's read the following rules.They can help you stay healthy.①Eat a__variety__of foods, especially fruit and vegetables.We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favourite foods.Remember that we can only get the nutrition(营养) we need by eating different kinds of food, especially fruit andvegetables.② Drink water and milk most often.Everyone knows that water is important.Besides that, kids need plenty of calcium(钙) to grow strong bones, and milk has a lot of it.Every day, you should drink at least three cups of milk (1300 milligrams of calcium), when you are 9 years old or older.You should also try to have less sugary drinks, like soda and coca.They include a lot of sugar.Sugar just includes calories, not important nutrition.③Listen to your body.When you are eating, notice how your body feels.When your stomach feels comfortably full, stop eating.Eating too much makes you feel uncomfortable.If you do it too often, it can make you unhealthy and fat.④ Limit(限制) screen time.What's screen time? It's the amount of time you spend watching TV, movies, and playing computer games.The more time you spend on these sitting-down activities, the less time you spend playing sports, like basketball, and doing other activities like bike riding and swimming.Try to spend no more than 2 hours a day on screen time.7．In this passage, “health” includes all of the following EXCEPT ________．A．eating wellB．doing more exerciseC．having a healthy weightD．wearing comfortably8．The underlined phrase “a variety of ” means “________”．A．a few ofB．a lot ofC．the rest ofD．all kinds of9．As kids, we should drink at least ________a day to grow strong bones.A．three cups of milkB．four cups of milkC．two cups of milkD．one cup of milk10．What's the main idea of the passage?A．How to eat healthily.B．Eating and playing are both important.C．Advice on staying healthy.D．Health is very important.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
