同时，本单元的语言技能和语言知识都是围绕“发明”这一中心话题设计的。
Pre-reading，Reading and Comprehending整体设计教学内容分析This is the first teaching period of this unit.The central part of this period is the reading passage with the name of The Problem of the Snakes showing the students an invention so that students can identify its stages.Warming Up gives three pictures for students to discuss.The point of this exercise is to emphasis the difference between a discovery and an invention，letting students get some more knowledge about discoveries and inventions.Pre-reading aims to help students focus on the topic of the reading passage and make the students aware of the connection between inventing and the scientific process.Get students to put the stages into a suitable order.Reading mainly introduces the problem of the snakes that needed to be solved.There are some stages of dealing with snakes in making an invention correctly.The way the inventor goes about it and particularly her efforts to improve the solution are very important to the inventing process.There are three pictures in the passage and each of them is used to present a stage of catching the snakes.After a glance at the title of the text and the three pictures we know that it is to describe a thing about catching snakes，in which there are many stage expressions.Then we can understand the topic of the text and how the information is organized.Comprehending consists of three written or oral exercises for the students to do so as to help the students to get a better understanding of the text，that is to say，to help the teacher check how much the students have understood the text.三维目标设计Knowledge and skills1．To know the meanings of the following new words and phrases in this period：patent（专利），courtyard（院子），walnut（胡桃），distinguish（区别；辨别），merciful（宽大的；仁慈的；慈悲的），product（产品），powder（粉末），perfume（香味），stainless（无锈的；不锈的），cube（立方体），abruptly（突然地），convenient（就近的；方便的），caution（小心；谨慎），expectation（预料），passive（被动的；消极的），merrily（愉快地；高兴地），seize （抓住），criterion（标准），valid（有效的；确凿的），file（提交），call up（给……打电话），now and then（偶尔，有时），set about（开始，着手）．2．To learn about some inventions，make clear the difference between a discovery and an invention and introduce students to the role of the patent office in deciding what an invention is and what is not.3．To learn how the information is organized.4．To develop the students' reading ability by skimming and scanning the passage.5．To develop the students' speaking ability by talking about inventors and inventions.Process and methods1．While doing Warming Up the teacher can lead in the topic of this unit by showing students some pictures of inventors and inventions，introduce some technical terms concerning inventors and inventions and develop students' understanding of what an invention is.2．During Pre-reading the teacher can go around the classroom and discuss the questions with several students.This discussion should be student-centered and arouse students' interest in inventors and inventions.The teacher should also ask the students some questions and try to let them have a general knowledge of inventors and inventions.3．While doing Reading and Comprehending，the teacher may first ask the students to read the text quickly to get the general idea of each paragraph.After detailed reading of the passage，students are encouraged to answer some questions and discuss the text structure.4．To consolidate the contents of the reading passage，the students should be required to retell the text in their own words at the end of the class.Emotion，attitude and value1．To stimulate students to love science.2．To develop students' sense of cooperative learning.教学重点、难点1．To enable the students to learn about inventors and inventions and to develop their reading ability.2．To enable

reported.According to Zhou Zhaolong，deputy director-general of southern China's Guangdong Association of Invention，one of the co-sponsors of the selection，China's “New Four Great Inventions” were voted for by both the public and experts in line with the requirements that they be creative and original，have worldwide significance and have a big social impact.60 percent of the votes were cast online，while 40 percent were taken from experts.On top of the list is hybrid rice，which was first developed in 1973 by Chinese scientist Yuan Longping，thereafter called the “Father of Hybrid Rice”．The new breed has enabled China，with its immense population but comparatively limited area of arable land，to solve its long standing food problem and contribute a great deal to the world food industry.Another major breakthrough，the techniques for Chinese character laser printing，was developed by late scientist Wang Xuan，known as “Bi Sheng，Father of Printing in Modern Times ”．First introduced to newspaper printing in December 1987，his techniques brought about a revolution in the printing and publishing industries.Allowing China's printing industry to bid farewell to its age of clay and lead printing，since being adopted Chinese laser printing has increased the efficiency of domestic printing，promoted the spread of Chinese culture，and had a far-reaching impact on the printing industries of other countries，including South Korea and Japan.Also，synthetic bovine insulin，which was fully developed in 1965 following 6 years of hard work by a group of Chinese scientists，was the first case of human beings synthesizing live proteins.The success made it possible for Chinese scientists to deflate the traditional concept that said synthetic live proteins were by definition impossible as life stems from nature.Synthetic bovine insulin marked a significant breakthrough in the field of life science and has substantially influenced human endeavors in finding out the secrets of life.Finally，artemether compound tablets，which were first developed in the mid-1980s by Chinese scientists，have proved to be the most effective anti-malaria medicine worldwide.With their brand-new chemical structure first discovered by Chinese，they are often compared to “Atom Bombs”，a milestone in the history of man's fight against malaria.Step 2Pre-readingAsk students if they know the stages every inventor must go through before they can have their invention approved.Encourage them to talk about it and look at the list on Page 19 to work out a suitable order.Suggested answers：1．Finding a problem2．Doing research3．Thinking of a creative solution4．Testing solution5．Deciding on the invention6．Applying for a patent Step 3Reading and comprehending1．Fast-reading：Ask students to skim the passage so as to get the key words and general idea of each paragraph and answer the question：What's the main idea of the text?________________________________________________________________________ Suggested answer：This text is mainly to introduce the writer's new idea of trapping the snakes and her application for a patent.2．Read the passage carefully，divide the passage into 4 parts and match

The criteria are so strict that it is difficult to get new ideas accepted unless they are truly novel.4. Nor will you receive a patent until a search has been made to find out that your product r eally is different from everybody else’s.2. Ability goalsEnable the students to describe the problem of the snakes and what has been done by the writer to solve the problem. Make them realize it takes steps to catch the snakes and it’s not easy to get a patent.3. Learning ability goalsHelp the students to learn how to retell the story and how to meet the requirements of getting a patent.Teaching important pointsHow to describe the problem of the snakes and what has been done by the writer to solve the problem.Teaching difficult pointsLearn how to meet the requirements of getting a patent.Teaching methodsTask-based activities.Teaching aidsA recorder, a projector and some slides.Teaching procedures & waysStep Ⅰ Revision1. Greetings2. Check the answers to the multiple choices in USING WORDS AND EXPRESSIONS.3. Ask some students to show the answers to the preview questions.T: Last period, you were asked to preview the text and answer the two questions. Did you get ready?Sample answers:1. The problem talked about in the text is how to catch snakes in the courtyard.2. The writer solved the problem in different steps. For example placing the frozen bowl and the ice-cubes on top of the bowl to keep it cool, freezing the bowl and ice-cubes again in the evening as the temperature was starting to cool and using a net used for catching fish.Step Ⅱ Pre-readingT: Problems can arise anywhere at any time. Now here is a problem of snakes. Look at the title of the reading passage. What can you guess about the content of the passage from the title? To answer the question you should try to predict the content of the reading material by reading the title and looking at the pictures in the text. The title of the text is THE PROBLEM OF THE SNAKES. Next, I’d like you to discussthis question with your partner. Then I’ll ask some students to report your work. Are you clear?After a few minutesT: Now who’d like to answer the question? V olunteer!S1: Let me try. Someone was once frightened at the sight of snakes, the brave and clever writer helped solve the problem of the snakes, as we can see from the picture that she finally caught them with a net.S2: Judging from the title, I think the passage is mainly about the serious problem of the snakes around the house and how the girl made efforts to catch the snakes in the end.S3: The title tells us that the content of the text will be about different ways of catching snakes tried by the girl and her success in doing it.T: Very good! Now, let’s go on with Exercise 1 in the pre-reading. Inventing is a scientific activity. Every inventor must go through certain stages before they can have their inventions approved. Look at the list of the stages and work out a suitable order. S: The suitable order of the steps every inventor must go through before they can have their inventions approved:1. Finding a problem2. Doing research3. Thinking of a creative solution4. Testing the solution5. Applying for a patent6. Deciding on the inventionT: Well done! You’ve worked the order out. Now read the text and check the order you wrote above to see whether it follows the correct stages in producing an invention. First, you should skim the passage by reading the introduction, the topic of each paragraph and the conclusion.After a few minutes.T: How about your arrangement of the stages? Are they all right?S: I find the above steps are correctly arranged according to the text. At first the writer found the problem of the snakes, and then she made a study of the methods ofcatching them and thought of a creative and practical way to solve the problem. She then tested and improved the method before applying for a patent and whether there will be a decision on her invention remains to be seen.T: Quite right. Since you have got the general idea of the text, let’s go through the text again.Step Ⅲ While-readingGet the students to comprehend the passage carefully and accurately, and then divide the text into several parts and work out the main idea for each paragraph.T: Now, please read the passage carefully, divide the whole passage into several parts and find out the main idea of each part.Part I (Para.1): the discovery of the problem of the snakesPart II (Paras.2-3): the research on the approaches to solve the problemPart III (Paras.4-6): the attempts to catch the snakesPart IV (Paras.7-8): the requirements of getting a patentT: Now, please go through the whole text again and I’d like you to analyze the text in details. Discuss these questions on the slides.Show the following.1. What are the writing techniques of this text?2. What’s the main idea of the text?3. What should we learn from this text?4. What’s the writing purpose of the writer?Sample answers:1. In this text the writer puts forward the problem of the snakes, makes research and analyzes the problem, lists the steps of solving the problem according to the arrangement of ideas, and finally illustrates what is needed for getting a patent. By listing the creative steps she takes to catch the snakes without hurting them, the writer has efficiently recorded and narrated to the readers the beginning, the development and the final result of the incident clearly.2. The text narrates the problem of the snakes and presents the procedures of catchingthem and applying for a patent, from which we have got a better understanding of how to do scientific researches and how to apply for a patent. After learning, we know that it usually costs some time and continuous efforts in order to solve some practical problems in a scientific way.3. We can learn from the text the way of doing scientific researches and how to apply for a patent. We can also learn that it takes an inventor great determination and persistence to achieve his or her ambition in life.4. The writer wants to inform us of the scientific methods to solve present problems so that we students can not only broaden the horizons but become more skilled in discovering and considering carefully the problems in daily life. We are also encouraged by the writer to be creative and hardworking as well as thinking independently.Help the students deal with the difficult language points in the text.T: Now, everyone, I wonder if you have any difficulties in understanding the text.S1: I have one question. I can’t understand the structure of the sentence in Para. 2 on page 20: The first thing I did was to see if there were any products that might help me, but there only seemed to be powders designed to kill snakes. Would you please explain it and put it into Chinese for us?T: Sure. This sentence tells us the first step of the writer’s research on the problem of the snakes. The words the first thing is modified by an attributive clauses I tried to do and the words powders is modified by an attributive past participle phrase designed to kill snakes. The clause if there were products that might help me serves as an objective clause. 全句汉语意思：我设法做的第一件事是看看是否有能帮我忙的产品，但是好像只有一些用来捕杀蛇的粉末。

________________________________________________________________________ ________________________________________________________________________教学参考Ten inventions that changed the worldTo mark its centenary，in June the Science Museum in London had its curators select the 10 objects in its collection that had made the biggest mark on history.These then went to a public vote to find the most important invention of the past centuries.Visitors to the museum and online voters cast nearly 50 000 votes.Find out the winners below.1．WinnerWith 9581 votes，the medical X-ray radiograph was deemed the most important invention in the Science Museum.In 1895 the physicist Wilhelm Röntgen discovered X-rays，the “X” signifying their then-unknown origin.He later found that the rays could pass through flesh and by using photographic plates could make images of bones inside the body.This X-ray of Röntgen's wife's hand was taken in December 1895 and is the oldest surviving X-ray image of a part of the human body.Andy Adam，president of the British Royal College of Radiologists，said，“Radiology is the most exciting and fast-developing speciality in modern medicine.The discovery of X-rays brought this discipline into existence and has benefited countless patients.”X-ray brochure,1930sThis cover of an advertising trade leaflet was produced by the equipment manufacturers Watson & Sons.By the 1930s，X-ray equipment was in widespread use for the diagnosis of a broad range of ailments，from broken bones to tumors and tuberculosis.X-ray machineThis X-ray set was made by Russell Reynolds just months after Röntgen's breakthrough.It is one of the oldest in the world and provided some of the first glimpses inside the human body that didn't need a scalpel.2．PenicillinSecond place—6825 votesFungal spores that drifted through these windows in central London led Alexander Fleming to discover the first antibiotic in 1928.By the mid-1940s，work in the UK and US led to the first penicillin reaching patients.That development marked the start of a wave of new drugs that have made a diagnosis of a bacterial infection far less threatening than it once was.3．DNA double helixThird place—6725 votesThis reconstruction of the first ever model of the DNA molecule contains some of theoriginal parts used by Francis Crick and James Watson in 1953.Their breakthrough made it possible to understand both how organisms pass on their genes and how the workings of cells are governed.And with genome sequencing becoming ever cheaper，we're only going to become more familiar with it.4．Apollo 10 capsuleFourth place—4649 votesForty years ago，three men travelled around the moon in this capsule as a rehearsal for the first moon landing，which took place two months later.5．V2 rocket engineFifth place—3985 votesIt powered a weapon used by the losing side in the Second World War，but the V2，invented in 1942，shaped the world for decades afterwards.The rocket's creator，Wernher von Braun，moved to the US after the war，where he worked on the nascent intercontinental ballistic missile program.He then worked for NASA，where he masterminded the Saturn V rocket that launched Apollo 11 to the moon.6．Stephenson's RocketSixth place—3533 votesBy achieving record-breaking speeds en route to winning the 1829 Rainhill trials in Lancashire，UK，Rocket steered the world towards mobile power instead of fixed engines pulling on ropes.Its designers，Robert Stephenson and Company，built it according to basic principles that became a standard for steam locomotives，carrying people and goods around the globe for well over a century.History could easily have been different.Another locomotive named Lucky proved capable of outperforming Rocket in the trials，but was less reliable.7．Pilot ACE ComputerSeventh place—3472 votesOne of the earliest general-purpose electronic computers，Pilot ACE ran its first program on 10 May 1950.At the time，it was the fastest computer in the world.The computer's design was a smaller version of a design by computing pioneer Alan Turing.Pilot ACE was selected because of its place in the first generation of computers that spawned the machines which surround us today.8．The atmospheric engineEighth place—3457 votesThe atmospheric engine was invented by Thomas Newcomen in 1712.This model was built to his design by Francis Thompson at a colliery in Derbyshire，UK，in 1791 and is the oldest Newcomen-type engine to survive complete and largely unaltered.The atmospheric engine solved the energy crisis of its day and heralded the start of the industrial revolution.It unlocked previously unreachable coal reserves by pumping water out of deep mines.Although this triumph of engineering arguably marks the start of the industrial age we still inhabit，it also marks the point that our dependence on fossil fuels really began.9．Model T FordNinth place—3231 votesThrough pioneering new ideas about mass production，the Ford Motor Company brought motoring within the reach of a huge new market.“Fordism” became a familiar metaphor for production of anything in large quantities，a philosophy that is now standard business practice.10．The electric telegraph10th place—2694 votesCharles Wheatstone and William Cooke patented the world's first successful electrictelecommunications device in 1837.Their telegraph was the first practical use of electricity for long-distance communication and led to the first public communications network.Those networks have been growing in strength，capacity and importance ever since.（From：/aw/archives/2279）。

人教版高中英语选修8Unit3《Inventorsandinventions》word教案【美文阅读】Wireless charging for mobile phones by 2020近日，日本的富士通公司宣布，他们开发出了一套能为手机等便携式电子设备无线充电的系统。
Fujitsu，a Japanese technology company，has created a system capable of simultaneously(同时地) charging many portable electronic devices such as mobile phones，digital cameras and laptops without the need for cable(电缆)connections.Electric car users may also eventually be able to charge their vehicles wirelessly using the same technology according to Fujitsu，which displayed a model system at an Institute of Electronics，Information and Communication Engineers conference.Claiming to be the world's first of its kind，the technology works on the basis of the transmission of electricity using magnetic(磁的)fields between the charger and the electronic device.The system makes it possible to charge wirelessly at distances of up to several meters，and Fujitsu aims to provide public “charging spots” on the streets in order to provide easy charging day and night.Scientists at Fujitsu Laboratories are planning to commercially sell products combining the new wireless charging system as early as 2020.Mobile phone users in Japan can currently charge their batteries using portable battery devicesavailable at most train stations and convenience stores－although phone companies warn this can damage the phones.The new system invented by Fujitsu，however，is much more advanced and represents the next generation of portable recharging systems using flexible wireless technology.The company added，“We are also looking at applying the results of thiswork to fields other than portable electronics，including power transmission between circuit boards(电路板) or computer chips，and providing mobile charging systems for electric cars.”【诱思导学】1．How does the wireless charging technology work?____________________________________________________________________________________________【答案】It works on the basis of the transmission of electricity using magnetic fields between the charger and the electronic device.2．When can consumers probably buy products using the new wireless charging system?______________________________________________【答案】As early as 2020.Period ⅠPreviewing(教师用书独具)●教学目标本课时要紧是通过学生对学案所给出的内容的学习，了解本课文中所显现的词汇，初步了解课文以及相关的背景知识，为下一堂课对课文的全面明白得起到一个铺垫作用。

With it, we can talk with friends, families or others far away from us. Suppose you want to apply for a job in James Dyson’s company in England. The quickest and cheapest way may be a telephone conversation. So you ring up one of his engineers to ask what kind of person he needs. Now work in pairs and make a telephone conversation with your partner. Remember to ask for as much information as you can. Of course, we have learned about how to make telephone calls in English-speaking countries. Who cangive me some examples?S: I’ll try. When making a telephone call, we often say: Hello! Is that... speaking? Yes, this is... Can I take a message? Wait a minute, please, and so on.T: But the following expressions may be of great help. Before listening, please read and learn them by heart.Show the following.Hold the line, please.Hang on, please.Just a moment, please.I’m sorry, but this phone is out of order.I can’t get through.I’ll ring him / her up again.I must ring off now because...T: Now, you may work with your partner and discuss about the questions and answers.A sample dialogue:(S-student; E-engineer)S: Hello! Is that James Dyson’s company?E: Yes, Who’s that?S: This is Li Ping. Is that the personnel manager?E: Just a moment, please. Sorry. He isn’t here right now. Can I t ake a message?S: No, thanks. Maybe I’ll ring him again some other time. By the way, May I ask you some questions?E: Sure, go ahead.S: I want to apply for a job in your company and I want to ask what kind of person you need.E: Well, as far as I know, we need some skilled workers who are good at machinery and have a good knowledge of repairing some electrical equipment used at home, for example washing machine, refrigerator, electric fan and so on.S: Are we graduates needed in some departments in your company?E: It’s hard to say now. Maybe you will have some chance to work and learn in some department, but you have to wait and see. If you are free, you may call the personnel manager at three o’clock this afternoon.S: OK, I will. By the way, how much will I get if I can work as your colleague?E: Usually the average salary for newcomers is $2,000 per month. And you may get a rise if you progress well or have some invention in your work.S: Well, I know. I must ring off now because I have to go back home for lunch. Thanks a lot. Bye!E: Goodbye and good luck!T: Next please swap roles and answer your partner’s questions. Remember you must behave as if you are a member of Dyson’s company and answer the questions honestly.Step Ⅱ Listening and speakingT: Zhou Rui has decided to do a project on a living British inventor called James Dyson. So he telephoned Dyson’s company in England to interview one of its engineers about the great man’s ideas. Now listen to the conversation betw een them and finish the exercises on page 26. Before that, please look through the introductions first.Ask the students to finish the exercises after listening and then check the answers with them.T: While listening, you’d better make notes of the list ening points like this:Show the following.The object of his invention:The problem of his invention:The improvement of his invention:Step Ⅲ LISTENING (Workbook)T: Millions of people in China and around the world use cellular phones. They are such great inventions —with a cell phone, you can talk to anyone on the planet from just about anywhere! These days, cell phones provide an unbelievable array of functions, and new ones are being added at a breakneck pace. Now look at the pictures and questions on page 62. Work in pairs and have a discussion about the three questions.Sample answers:S1: A mobile phone can now be used to receive phone calls, send and receive messages, listen to music, watch videos, surf the internet and so on. I find it very useful to use the mobile phones to make telephone calls and send and receive messages because we should always be informed and it’s important and ne cessary to communicate with each other in modern society. I also expect a mobile phone to show pictures of the person I call so that we can see clearly whether we are calling the right person and I hope one day we can use it to have meetings with people in the distance, and see films and show DVD in public.S2: Nowadays mobile phones can be used to do calculations, record pictures in life, play games, chat online, set time limit, wake up people, find out various information online and so on. I find they are very useful because we can enjoy ourselves when we use them to play games and chat online and talk with friends about different subjects.I expect mobile phones can be used one day to watch TV, cook meals, pick up foreign languages, do homework and take e xams for me. Then I’ll be free from different kinds of worries and complaints and live a more comfortable and convenient life in the future.T: Good! You have known much about mobile phones and we’ll listen to some other functions of them, which you might feel more interested in. Now, listen and do Part 2 and then answer the questions in Part 3. While listening, please make notes as follows. OK?Show the following.The mobile Mary will buy:The extra applications of mobiles:The extra application of the 3-G mobiles:The reason why Mary is worried:The advantages of the 3-G mobiles:What might go wrong?Then check the answers with the students.Step Ⅳ LISTENING TASK (Workbook)Deal with the LISTENING TASK on page 67.T: First look at the three pictures on page 67 and discuss what inventions they might be.
