Using LanguageGOOD DESIGN IS PRACTICALZhou Rui (ZR) made a phone call to Dr Smith (S), an engineer who works for James Dyson, a famous British inventor. Now Dr Smith is ringing him back.Listen again and fill in the blanks.S: Hello, can I speak to Zhou Rui please? This is Dr Smith.ZR: Good morning, Dr Smith. How kind of you to ring me back! Would you mind if I asked you a few questions about James Dysons inventions.S: Not at all. Id be happy to talk about our company and our founder, James Dyson. Hes an inventor who takes everyday products, like washing machines, and makes them work better.ZR: I see. Why did he improve the washing machine?S: He found that clothes were not as clean from a washing machine as those washed by hand.ZR: Really? Is that true?S: Yes, because most machines have one large drum and the clothes go round and round in it.ZR: So what did he do to improve that?S: This is the clever part. James Dyson invented a system with two drums in the same machine. Together they are the same size as the old drum, but they work differently. One drum goes in one direction and the other goes in the other. So its more like hand-washing and the clothes come out cleaner.ZR: Was it easy to design?S: No. It took many working models before Mr Dyson was satisfied.ZR: How long did it take him?S: Im not sure. But I do know that inventing a new carpet cleaner took five years before he was happy with it.ZR: Wow! I didnt realize that it took that long! S: And of course he had to apply for patents for all of the new parts hed designed. You must do that to protect your ideas.ZR: Has that been a problem?S: Well, in the early years, James Dyson found that a large company making carpet cleaners in America was copying his ideas. He had to go to court to protect his invention.ZR: Did he win?S: Yes, in the end the company had to pay us a lot of money.ZR: What new ideas does James Dyson have?S: Im sorry but youll just have to wait and see! ZR: Thank you very much and Im afraid I shall have to ring off now. Goodbye.S: Goodbye.Workbook-ListeningWHICH ONE SHOULD I CHOOSE?Ruth Bacon (RB) is asking her friend, Zhang Jie (ZJ), for advice.Listen again and fill in the blanks.RB: Hello, is that Zhang Jie? This is Ruth. Im thinking of buying a new mobile phone. What do you suggest?ZJ: Hello Ruth. Im happy to help. Its lucky you could get through. Ive been having some trouble with the line and I keep getting cut off. If the line goes dead, ring me back immediately on my mobile and it should be OK. Now what do you want your mobile to do?RB: Well, Ive heard about mobiles that are computers and can videotape as well. Do you think theyre a good idea?ZJ: Mmm. Yes, theyre useful. I can use the Internet even when Im on the train.RB: So you suggest one like that then?ZJ: Not necessarily. It seems therell be some new mobile phones coming on the market next year. Theyre going to be even more powerful.RB: What are they going to do?ZJ: Oh, youve no idea what theyre planning! These new phones will be able to organize your life. Theyre called 3G phones because theyre the third generation of mobile phones. They “think” for you.RB: How can they do that?ZJ: Well, theyll be able to help you plan a holiday. The phone will book air tickets and the hotel. Then itll pay for you.MB: Wow! Im not sure Id be happy with that! I dont like the idea of a machine spending my money.ZJ: Well, many businesses already use mobile phones to buy goods. They leave them to order goods when they are at their cheapest.RB: Do they really? Well, I never! What I need is a mobile to stop me missing important calls. I missed three yesterday because my mobile was switched off. ZJ: You can have that too. Theres a new mobile coming out soon that will turn itself on when important calls come through.RB: Are you sure? If thats the case, thats the one for me! Thank you, Zhang Jie, I think Ill wait for that one. Goodbye.ZJ: Goodbye.Workbook-Listening TaskWHAT CAN IT BE?Ellie Smith (ES) is discussing with one of her friends Tang Ling (TL), what this invention by Leonardo might be. Listen again and fill in the blanks.ES: Look at this drawing! What do you think this is supposed to be?TL: I dont know! It doesnt say, but lets see if we can work out what it is.ES: OK. Now lets see. It looks a bit like a tent but has four wheels underneath.TL: Youre right, but when you look at the second picture with the wheels, you can see that it had a floor to stand on and wheels below that. Do you think it was a roundabout for children? ES: Good thinking. But the way that he placed the wheels shows that it must have been for going forwards and backwards, not round and round. No, I dont think it was a roundabout.TL: Lets look at it again. Do you think its made of metal? The wheels seem to have handles to move them.ES: In that case it must have been large enough for more than one person. You would have needed four people one to move each wheel. So it cannot be a tent as that is made of cloth.TL: Yes, I think youre right.ES: It also seems to have something like sticks coming out of the body. Do you think they are for decoration?TL: Perhaps. That is possible as we know Leonardo was an artist.ES: Yes and if that were the case, perhaps it was for fun for the family. It could carry four people to move the wheels and then another one or two children to help. Maybe six altogether.TL: Wow! So it must have been made of metal. Nothing else could carry all that weight.ES: True! The wheels must be made of wood or metal.TL: Do you think its a caravan?ES: Yes, that makes sense. It would be big enough but th
