NSEFC2B Unit 18全单元教案（人教版高二英语下册教案教学设计）I .Brief Statements Based on the UnitThis unit provides the students good English language materials. Their interest in creating something useful will be aroused. In the first period, we' 11 begin with how the students come to school. Then problems such as flat tyre will come up. In order to solve the problem, we' 11 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 text 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 Goals 1. Talk about inventions.S:No, it isn' t. What should it look like then?Please tell us.T:0K.Let' s watch the short video.(Play the video for explaining how an inflatable bicycle works.)T:Thats 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' 11 not have 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' 11 buy one when it is on sale. We know that inventions can make our life easier and better. Today we 11 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.)T: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.Im not sure about the others.T:GoodYou' 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!P m sure you have got a wonderful idea. Maybe one day you can invent such things. Study hard and you' 11 be an inventor in the future. Now, lets 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 invention in your spare time. Now, let' s look at the fourth picture.Does anybody have an idea?T: 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 our bikes 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 ourearth.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 widely. 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 ListeningU: (A few minutes later. )Are you ready?Ss: Yes.T:0K. 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 V SpeakingT:Well done. Now, you' ve known how to apply for a patent. Lets 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 invention is a good idea or not. And I 11 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 ofHow 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, thats 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. Whats 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)Whats your invention, please?D:It' s a pen that can automatically translate what you write 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 want to 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' 11 make your own inventions in the future. In the next period, we' 11 read about how to be creative and how to be an inventor. It' 11 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 VH The Design of the Writing on the BlackboardUnit 18 InventionsThe First Periodelectric shoe inflatable bicycleedible chopsticks nose-top computer cStep VUI Record after TeachingThe Third PeriodTeaching Aims:1.

(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 strange to yotuDon' t worry. I' 11 give you some cards. Theres 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.

We know that it is a very important grammar item, so let' s do some more exercises to consolidate it. Turn to Page 61, and finish Exercise 2 in Grammar part.(Allow the students a few minutes to finish it and then check the answers.)Suggested answers:1. The wires with which the machines were connected were very old.2. Leonardo da Vinci, who was interested in both literature and science,painted the famous “Smiling Mona Lisa”.3. The pilot with whom we had dinner told us stories about his travels.4. The four ancient Chinese inventions, which we are proud of,have remained important in human history for thousands of years.5.
