first period,we’ll begin with how the students come to school.Then problems such as flat tyre will come up.In order to solve the problem,we’ll see a new type of bicycle and other new inventions.While talking about them,the students’ speaking ability will be improved.Listening is about two men,who want patents.After listening to it,the students will improve their listening ability.And students will practise how to express and support an opinion in the speaking part.In the second period,the tex t will be dealt with.The students’ interest of creation will be greatly aroused.Students will improve their reading ability as well as master the useful words and expressions.In the third period,some useful words and expressions will be mastered by the students after they finish the exercises.Also,the Attributive clause is reviewed in this period.In the last period,students will learn some useful words and expressions from the reading passage.And the students are asked to write an article describing a computer to improve their writing ability.After Ss study the whole unit,their abilities to listen,speak,read and write will be improved.Ⅱ.Teaching Goals1.Talk about inventions.2.Practise

the FutureWhere is television going from here?T elevision,the box itself and what it does,is changing greatly.While nobody is really surewhat it’s going to look like,TV and the Internet are coming silently together.In the old days of broadcasting,people used to say that the real miracle(奇迹)of television was turning air into money.The television miracle of the future is interactive(相互影响的).“The Internet is the most significant change in creating what becomes the next mass media that I think any of us will experience in our lifetime,”says Tom Frank,a network ing unused lines in the TV spectrum(范围),broadcasters are learning how to put brand-new interactivity into TV programs.There will be a little instrument that will indicate that interactivity is present and possible.Then,just will a standard remote control like this you would be able to press one button and say,start that interactivity.A menu would appear,similar to the one on a web site,that would let you interact with the program as it was being broadcast.If you are watching a cooking show,for example,you can print the recipe(烹饪法)or even pause the show and buy the ingredients.Many web sites do exist now where you can actually get your food shopping done for yourself and delivered to your house.So you can order the very ingredients for the dish you are watching the chef make on TV.And it will bring the right quantity of things directly to your house.You could also interact with TV commercials.While you’re watching a commercial,you have the choice to buy the clothes the actors are wearing.Of course,the more you interact with this new sort of TV,the more you leave a digital record,and the more advertisers learn about your shopping habits.In fact,TV ads might be targeted at this special group of people who share a common interest.In the future,almost anything might be possible.Even news programs like World News Tonight could be improved.Youcould have the choice of changing camera angles.If you wanted,you could pause what a reporter is saying and go back to World News Tonight to watch the next story,or skip to the last story in the show,or perhaps go deeper into a topic and view an interview prepared for Nightline later on.In the near future,you’re expected to see television develop to become more like the Internet,meaning more choice,the ability to do the sorts of things you want to do at the moment you wish to do them.Ⅳ.Teaching Time:Five periodsThe First PeriodTeaching Aims:1.Improve the students’ listening ability.2.Talk about some topics about inventions and practise supporting an opinion.3.Learn and master some useful words and expressions.Teaching Important Point:Train the students’ listening and speaking abilities by talking about and listening to some materials.Teaching Difficult Points:1.How to help students to improve their listening ability.2.How to help the students to learn to express and support an opinion.Teaching Methods:1.Discussion to make students talk about inventions.2.Individual or pair work to make students practise their speaking ability.3.Listening practice to improve the students’ listening ability.Teaching Aids:1.the multimedia2.the blackboard3.some cardsTeaching Procedures:Step Ⅰ GreetingsGreet the whole class as usual.Step Ⅱ Warmin g-up and DiscussionT:(Walk to one student.)How do you come to school every day,Wang Jing?S:I come to school on foot every day.My home is quite near.It only takes me about ten minutes.T:That’s quite convenient.You’re lucky.And,Li Fang,how about you?S:I come to school by bike.It takes me about 15 minutes to get to our school.T:You must be careful on your way to and from school.There must be many people on the road.Do you think it convenient?S:Most of the time it is,but sometimes my bike has a flat tyre.I have to get it repaired and therefore I’ll be late for school.OnceI even lost my bike.When I went to get it,it was gone.I had to takea taxi to go home and buy another bike.T:I’m sorry to hear that.But suppose a new type of bike has been invented,what do you want it to be like?S:I think the new type of bike can be folded up and carried about so that it will not be stolen.T:Good idea.But this is not very convenient.It’s not easy for you to carry a bike around,is it?S:No,it isn’t.What should it look li ke then?Please tell us.T:OK.Let’s watch the short video.(Play the video for explaining how an inflatable bicycle works.)T:That’s the new type of bike.It’s a kind of inflatable bicycle.Who can tell us the advantages of it?S:Let me have a try.We’ll not h ave to worry about having our bikes stolen again.Because we can let the air out and put the bike in bag.It’s very convenient to be carried around since it is not heavy.T:Very good.I think I’ll buy one when it is on sale.We know that inventions can make ou r life easier and better.Today we’ll talk about some inventions.(Stick the pictures of electric shoes,inflatable bicycle,edible chopsticks and nose-top computer on the blackboard and then mark one,two,three and four.)① ②③ ④T:Look at these pictures,please.Do you know what they are?Li Jie,will you have a try?S:I think the second invention is the inflatable bike that we’ve just talked about.In the third picture,the man is eating the chopsticks after his meal.I guess these chopsticks are edible ones.I’m no t sure about the others.T:Good.You’re right.The second one is the inflatable bicycle.(Bb:inflatable bicycle)and the third are edible chopsticks.(Bb:edible chopsticks)They’re delicious and environmentally friendly. We can save some trees and have a snack at the same time.They come in five different flavours. You will never need to wash chopsticks again.Isn’t this wonderful?S:Yes,it’s great.But,Miss Guo,maybe we could invent edible plates,bowls,cups and so on.T:Oh,you’re great!I’m sure you have got a wonde rful idea.Maybe one day you can invent such things.Study hard andyou’ll be an inventor in the future.Now,let’s look at the first picture.Who knows what it is?S:I think it is a special kind of shoe which can make electricity.If we wear such shoes,we can see the road in dark places.We needn’t take a flashlight with us any more.S:I don’t quite agree with you.Maybe this shoe can make you feel warm using the electricity it makes.T:You both are very clever.This is called the electric shoe.(Bb:electric shoe)The heel of this shoe is a machine that makes electricity with every step you take.You will never need batteries again.But maybe you have better ideas about how to make use of the electricity it makes.If you like,you could have a try to make your own inventi on in your spare time.Now,let’s look at the fourth picture.Does anybody have an idea?S:It looks like a computer which is fixed onto the man’s nose.And the keyboard is on his vest.I can’t believe it.T:Yes,you’re quite right.This is called the nose-top computer.(Bb:nose-top computer)This new nose-top computer weighs less than a pair of glasses.It fits comfortably on your nose.When you want to type something you can use the keyboard vest.You will never have to carry a heavy laptop computer.These inventions are all wonderful.But which of them do you think would be useful?Please have a discussion in groups of four and tell us why you think so.(Ss have their discussions in groups of four for about five minutes.Teacher may ask one group to act out their discussion or report their results.)Sample dialogue:A:I think the inflatable bicycle would be useful.Because it’s convenient to carry and we needn’t worry about having ourbikes stolen.B:That’s quite true,but I think the edible chopsticks are useful.Because it not only saves trees but also saves water.It is very important to save our natural resources and protect our earth.C:You’re quite right,but I have a different opinion.I think the nose-top computer is useful.Because the computer is used more and more widel y.It’s convenient to carry such a computer around when doing business.…Step Ⅲ Preparation for ListeningT:We know that when someone has invented something,usually he will go to a patent officer to apply for a patent.Now,let’s listen to two dialogues.In these two dialogues,Mr Dean and Mr Scoles both have invented something.They’re trying to get the patent for their inventions from the patent officer.Before we listen to the tape,go through the questions on Page 15 by yourselves,and see what we should do after listening.Step Ⅳ ListeningT:(A few minutes later.)Are you ready?Ss:Yes.T:OK.Listen carefully and answer the questions first on your own and then check your answers with your partner.(Play the tape twice for students to listen to and then answer the questions.Play it a third time for students to check their answers.Allow the students a few minutes to check their answers in pairs.At last,check the answers with the whole class.) Step ⅤSpeakingT:Well done.Now,you’ve known how to apply for apatent.Let’s play a game.Each of you will be given a role card.Work in groups of five:four inventors and one patent officer.Each inventor should explain how the invention works and why it is useful.The patent officers should ask questions and decide if each inventio n is a good idea or not.And I’ll show you some useful expressions to help you.(Hand out the role cards and show the useful expressions on the multimedia.)Useful Expressions:This invention can help people…What does it look like?What’s it made of?This is a new way of…How does it work?How would people use it?This new invention will make it possible for people to…(Students work in groups of five and have a discussion for about five minutes.Then the teacher may ask some groups to act out their discussion.)Sample dialogue:(A-Inventor A;B-Inventor B;C-Inventor C;D-Inventor D;P-Patent officer)P:Now,please explain how your inventions work and why they are useful.Your invention is a car that uses water instead of petrol,isn’t it?A:Yes,that’s right.P:What does it look like?A:It looks like an ordinary car.Here’s the picture.Please have a look.P:Oh,it looks beautiful.What’s it made of?A:It’s made of a new kind of alloy,which is much lighter.P:Does it cost more?A:A little bit.But it can save much more energy,so lots of money is saved.Besides,there is something even more important.It is good for our environment.It doesn’t pollute the air.P:Sounds great.Thank you.And what’s your invention,sir?B:My invention is a flying bicycle.P:A flying bicycle?How would people use it?B:People can ride it on the road and when there are too many bicycles,people can fly it.Just push one button on the handle,the bicycle will fly.P:How does it work?B:It works like a small plane.It has a special engine.P:This is a new way to improve our traffic condition.Thank you.(To C)Would you please explain your new invention to me?C:My invention is a machine that makes it possible for people to know the future.P:How would people use it?C:People just input their date of birth,hobbies,dislikes and anything about themselves,and then press the button,wait for a moment,and they will see the result on the screen.P:That’s interesting.Thank you.(To D)What’s your invention,please?D:It’s a pen that can automatically translate what you wri te into a foreign language.P:Good.It can help people communicate freely with foreign friends.People needn’t study foreign languages hard any more.But,maybe it will make it more difficult for people to communicate orally.They will have to write down what they wantto say.This is not convenient. For the flying bicycle,what if there was something wrong with it when it was flying in the air?I think it would be rather dangerous for the people walking on the ground.Maybe the bike would fall onto them and cause an accident.Of course the rider would be in danger,too.For the machine that makes people know the future,I don’t think it’s a good idea for us to know our future too early.I think the most useful invention is the car that uses water instead of petrol.So I will give the inventor of this new car a patent.A:Thank you,sir.Step Ⅵ Summary and HomeworkT:Today we’ve learnt how to express and support an opinion.And we’ve learnt how to apply for a patent when you have made an invention.Many of you have wonderful ideas about new inventions.Study hard now and I believe you’ll make your own inventions in the future.In the next period,we’ll read about how to be creative and how to be an inventor.It’ll be very useful for you.Preview the reading part carefully after class,please.OK.That’s all for today.See you tomorrow!Ss:See you tomorrow!Step Ⅶ The Design of the Writing on the BlackboardUnit 18 InventionsThe First Period① ②electric shoe inflatable bicycle③ ④edible chopsticks nose-top computerThe second periodⅠ Teaching Aims:Learn and master some new and important language points;Improve the Ss’ reading ability by reading and comprehending the text;Get the Ss to learn how to be creative.Ⅱ Teaching Focuses:The main idea of the text.Finish all the reading comprehension exercises.The four thinking strategies.Ⅲ Teaching Methods:Question-and-answer activity. Some games.Group work, pair work or individual work to make every student work in class.Ⅳ Teaching Aids:1．A multi-media computer 2．A tape recorder and a tape.Ⅴ Teaching Procedures:Step 1 Lead - inShow a picture of a bulb to the students. Ask: Who invented it?Then show the portrait of Edison to the students. Ask: Do you know anything about his childhood? If they don’t, tell them sth. about his schooling, and then say: People are not born creative, and you don’t have to be very intelligent to be an inventor. We can learn to be creative. Today we’ll learn how to be creative.Step 2 Pre-readingScan the title and the four sub-titles, and guess what’s the text about?A. how to become a great thinkerB. how to improve your IQC. how to become more creativeStep 3 Fast-reading1.What’s creative thinking?It is one of skills and habits.2.How do people come up with ideas for new inventions? In how many ways?By good thinking strategies.Step 4 Careful-readingT: well, now let’s read the text carefully by listening to and reading after the tape one paragragh after another. You are required to finish off all the comprehension tasks for each part.Part 1: general idea.Part 2: What is to “think outside the box”?To think outside the box is to try new ways to solve a problem.To rephrase a problem to allow for creative solutions and also try “impossible” or “crazy”solutions.To make a conscious effort to break away from old thought patterns.Game 1: How do you connect all the dots with only four straight lines?Game 2:Mike’s father is a policeman. Why did Mike recognize him among his workmates though they were all in uniform?Who never goes to see a doctor,even when he is ill ?It is leaking( 漏水 ) everywhere in the office on a rainy day, why nobody has got wet?The plane crashed, but there were nobody injured. Why?Why a river richer than a bank?Part 3: Take another look at ita change in perceptionto look at a problem in as many way as possibleEach new way of looking at a situation improves ourunderstanding and makes it easier to discover new possibilities.Game 3:Can you only see a pot? Pay attention to the dark!Two faces!Part 4: Make connectionstry to combine new and old ideas in as many different ways as possibletry to make connections that may seem strange at firstthink of new applications and solutionsPart 5: Keep tryingdevelop new ideas even when they were tired or did not feel inspiredFor each new invention that works, there are at least ten that do not.Step 5 Post-reading1. Match the examples with the right titles:Example 1: think outside the box.Examples 2&3: keep tryingExample 4: take another look at it.Example5: make connections.2. T or F exercises.1) Most inventors have high IQs.2) The things we know can sometimes make it more difficult for us to understand.3) It’s impossible to learn how to be creative.4) The best way to find a good solution is to look for one good answer.5) Inventors try to avoid failure.6) The more ways we have of looking at a problem, the more likely it is that we can find a solution.7) Most good ideas are the result of a long process of trial and error.3.Reading comprehension.1) We can get the conclusion from the fifth paragraph that ____ A. to be clever can lead to success B. he who laughs last laughs bestC. failure is the mother of successD. never too old to learn2). The sentence “ good ideas are no accident” means the following except that ____A. Good ideas never come by chance.B. The accident is not caused by good ideas.C. To be successful needs many trials and errors.D. Failures can also help us move towards a better solution.3). Another proper title for the text is probably ____A.CreativityB.Great thinkersC. How to solve problemsD. ConnectionStep 6 Discussion (Groupwork):1. How do you understand the title of the passage?If we want to be creative, we should follow these rules---think outside the box, take another look at it, make connections and keep trying. These rules also work when we solve a problem .2. What other rules should you have if we want to be creative?3. Of all the rules discussed above, which one do you think is the most important? Why?Step 7: HomeworkP 61 Exx 1 & 2.P 131 Exx 1, 2&3.Ⅵ Bb writingOn slides. No writing on the BbThe Third PeriodTeaching Aims:1.Review the useful expressions learnt in this unit.2.Learn the derivatives of some words.3.Review the Attributive Clause.Teaching Important Points:1.The useful expressions learnt in this unit.2.Review the Attributive Clause.Teaching Difficult Point:How to help students master the Attributive Clause.Teaching Methods:1.Review method to consolidate the useful expressions learnt in the last two periods.2.Practise to help students master the derivatives of some words.3.Different kinds of practice to help students master the Attributive Clause.4.Pair work and individual work to make every student work in class.Teaching Aids:1.the multimedia2.the blackboard3.some pictures and cardsTeaching Procedures:Step Ⅰ GreetingsGreet the whole class as usual.Step Ⅱ GrammarT:Today we’ll play a game first.(Stick some pictures of famous people on the blackboard.Cf:The Design of the Writing on the Blackboard.)Look at the blackboard,please.These are pictures of some famous people.Do you know them?Maybe you’re familiar with some of them,but maybe others are strangeto you.Don’t worry.I’ll give you some cards.There’s one sentence on each card.The sentence describes a famous person.Guess the name of the person first and then match the card with the picture.Do you understand?Ss:Yes.(Teacher hands out some cards on which are the sentences in Word puzzle.)T:Now,please have a short discussion to find out who the person is and then match the card with the picture.When you find out the answer,please come to the blackboard,stick the card and write the name below the picture.(Students prepare for a moment and then they begin to match the cards with the pictures.)T:Have they matched the cards with the pictures correctly and got the correct names?Ss:Yes.(If there’re any mistakes,teacher may ask some students to correct them.)T:OK.Now,fill in the word puzzle using the names of the people that you’ve just found out.(Stick on the blackboard a piece of paper with the word puzzle on it.)(A moment later,ask several students to write down their answers.Cf:The Design of the Writing on the Blackboard.)

功能项目为描述发明的用语及问题。
教材的内容相对容易，功能用语简单，活动单一，笔者认为如果单纯地教教材内容会显得苍白，学生无话可说，不利于他们的参与和培养创新精神，因此，增加了一个大任务，就是让学生学习发明的常见步骤的同时，学习、巩固、自由运用功能项目中要求的语言和训练科学思维。

昨天傍晚，村干部已经派来抓泥机，将厕所后面的三个作为化粪池的坑塘挖完，并将三个大水泥管丢进了坑塘。小来宝来到这里，只要将坐便器安放妥当，接上三连通，再用水泥砂浆封闭一下，就 算大功告成。
原来我家厕所的蹲位有点偏高，小来宝挥动电镐，用去一支烟的功夫，下挖一些，深度刚刚好。待到清理完刚被打起来的碎砖渣，他拿来一个坐便器，准备安装。
我说：“你继续把另一个蹲位打完，再一起安装吧！”
“村里每一户只批准安装一个。”小来宝说，“假如你家男女厕所都装，请你份外再拿出七十元钱，才能给你安装。绝不准搞特殊。”
喔，却原来还有这样的规定，男女两个坐便器，只能够安装一个。我拿起手机，与去虚沟女儿家的妻子通了电话，说明道理与原委，我转告小来宝说：“你在这儿干着吧，我去街上，买一个更好些 的坐便器来，给你帮助装上。”

本单元的中心话题是发明，其中涉及科学技术发展、人的思维、思维的品质和对发明的新认识等。
就speaking 部分而言，教材中提供的内容是四个虚构的发明者向专利局官员描述各自发明而希望获得专利的情景。
功能项目为描述发明的用语及问题。
教材的内容相对容易，功能用语简单，活动单一，笔者认为如果单纯地教教材内容会显得苍白，学生无话可说，不利于他们的参与和培养创新精神，因此，增加了一个大任务，就是让学生学习发明的常见步骤的同时，学习、巩固、自由运用功能项目中要求的语言和训练科学思维。
另外，在本节课前让学生去了解一些著名发明家的信息为上课做准备。
3. 教学目标1) 学习教材中要求的关于描述发明的常用语言；2) 增加语言输入量，提高语言表达能力；3) 培养学生对发明创造的兴趣、提高科学意识；4) 让学生在小组互动中提高自主、合作和探究的意识。
4. 教学重点与难点1) 熟练掌握要求的描述发明的语言；2) 鼓励学生综合、活化新旧知识和语言阐述对象；3) 学生能通过讨论和合作提出一个发明想法并介绍给他人。
5. 教学辅助材料本次采用多媒体辅助教学，适当利用板书，在课堂上分发给学生的有：（1）每四人小组一张写有一项发明的纸条（各组不同）；（2）每四人一张专利申请表（各组相同）。
三．教学设计1．总体思路：高二学生已经有了一定的英语知识和科学知识，所以选择适当难度的相关材料和设计多样的活动是学生积极参与课堂的保证。
除教材本身的内容稍加改动纳入课堂教学以外，笔者设计了一个大任务即发明步骤和若干小任务来活化教材并加入了较多的有关发明和发明家的信息。
整堂课的总体程序为：猜发明家—发明的定义—发明的步骤—小组尝试小发明—发明介绍—总结。
各个环节相对独立又层层递进环环相扣，而每一步骤的重点稍有不同。
语言操练由简单地、机械地半控制性的句型表达到半开放性一直到自由组织。
在设计教学活动时，贯穿任务型教学原则，而任务源于教材，又不拘泥于教材，根据学生实际设计出一系列教学任务，课堂上输入尽可能真实的语言材料，提供给学生明确的指示，让他们通过真实或是模拟的情境中用英语做事，不仅学到了语言知识和开展各式合作学习，还了解了一项发明从无到有涉及到的方方面面。
2．教学过程Step 1 Lead-inActivity 1: Flash some pictures of famous inventors like Edison, Cai Lun on the screen twice for Ss to guess who they are and ask:What do they have in common?What do inventors have in common?［设计说明］教师快速闪现一些发明家的图片除了为本课话题做准备以外，更重要的是在第一时间抓住学生的注意力，以便开展接下来的活动。
学生回答科学家的共性时肯定是不全面的，在这一阶段，教师无需强求，因为在本课最后总结时还会重新提到。
Step 2 DefinitionActivity 2: Ask Ss to tell the definition of invention.［设计说明］本单元的话题是发明，简单地解释它很有必要，而一直以来人们对发明的定义莫衷一是，学生可以通过自查字典或其他方式了解它的不同定义，而教师只提供众多定义中的一种而已：An invention is something produced for the first time through the use of imagination or ingenious thinking and experimentation.Step 3 General TaskDiscussion: Ask Ss to discuss in pairs about what steps should be followed when making a new invention and then share their opinions with the whole class.［设计说明］从这一步开始就进入了整堂课的大任务阶段。
任务的主要目标在于让学生了解一项发明从无到有的过程和其基本的步骤，以便在平时能够自觉或无意地加以运用。
课堂上的各种活动也都是围绕着这一任务展开的。
具体的又分成五个小任务，也就是发明的五个步骤，每个步骤里面又包含着若干小任务。
2. Learning About Inventors and InventionsActivity 1: Show Ss six big numbers on the screen and each number is linked with somestatements which describe an inventor or invention with four sentences. Ss are divided into four groups to have a competition to guess what/who it is.［设计说明］要想做出一项发明，应该有一定的知识积累，有效的方法之一是学习发明家和他们的发明。
为了让学生了解这一点，本人设计了两个任务。
第一，看信息，猜发明。
把一种发明或一个发明家对象的信息分四部分给学生呈现，让学生猜测，信息的提供方式有文字、图片和录音，每一种对象的猜测难度不同，由学生自由选择。
每一个对象描述中都包含有本节课的功能项目－－描述发明的表达用语。
这样的语言输入方式自然，学生注意力集中，积极性很高。
教师在活动结束时总结一下语言点，为下一个任务做准备。
以下就是用来猜测的六个对象，难度从小到大，每行结尾处的数字是猜出时的分值。
根据现场学生的需要做全部或部分。
1）（难度最低，猜中得分最低）•It’s made of metal. （呈现这句话让学生猜，猜出答案可得相应分数）50•This invention looks like a bird. 40•It makes it possible for people to fly to different places in the world. 30•It is powered by an engine and is flown by a pilot. 20•Airplane2）•This invention can help people in the street. 60•It looks like a tree standing beside the street. 50•It directs cars and trucks (40)•…by using colored lights. Red means stop, green means go. 30•Traffic light 本题通过听力形式给出信息3）•He was a world-famous inventor. 70•Here is one of his photo. 60•He was a Swedish. 50•He invented dynamite (炸药) 40•Alfred Nobel4）•The invention looks like a chair. 80•It has a pipe through which the waste can go. 70•People use it to eliminate their bodies waste material. 60•It is usually made of china these years. 50•Toilet5）•No one knows the exact inventor of it. 90•The invention can help people open and close things by locking•little hinges together. 80•It’s made of met al or plastic. 70•It’s usually on coats and backpacks, sometimes sweaters. 60•Zipper6）（难度最高，猜中分数最高）•This is a new way of keeping money. 100•You press a button to open the drawer in which you can put the money. 90•It makes it possible for people to record the amount of money received. 80•It is mostly used in stores or supermarket. 70•Cash RegisterActivity 2: Ask each group to describe an inventor or invention in the similar way and letothers guess according to the information given.［设计说明］学生的语言输入以后，设计的输出活动是：一部分学生描述，其他猜测。
