Step Ⅱ Warming-up and Discussion

T:(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.Once I even lost my bike.When I went to get it,it was gone.I had to take a 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 like 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 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’ll buy one when it is on sale.We know that inventions can make our 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 ②

③ ④

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.I’m not 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 wonderful idea.Maybe one day you can invent such things.Study hard and you’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 invention 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 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 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 widely.It’s convenient to carry such a computer around when doing business.

Step Ⅲ Preparation for Listening

T: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 Dea …… 此处隐藏：7961字，全部文档内容请下载后查看。喜欢就下载吧 ……
