Listening and speaking
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.
1. Listen to the tape and tick the words you hear. √ washing machine □ □ √ drum √ □ refrigerator □ court □ □ bicycle √ carpet cleaner
2. Listen again and make notes on James Dyson’s invention.
Object The Problem James Dyson’s improvement

clean the clothes as well as by hand.
which move in opposite directions.
GOOD DESIGN IS PRACTICAL
Zhou Rui is making a telephone
call to an engineer who works for
Janes Dyson, a famous British inventor.
DS: Hello. Can I speak to Zhou Rui, please? This is Dr Smith. ZR: Gook morning, Dr Smith. How kind of you to ring me back? Do you think you can accept my phone interview now? I’m very interested in James Dyson’s inventions and ideas.
DS: Sure. I’m happy to speak about
our company and its founder,
James Dyson. He is not an
inventor who makes something
entirely new. He takes
everyday products, like
washing machines, and makes
them work better.
ZR: I see. How did he improve the washing machine? DS: He found that clothes were not as clean from a washing machine as those washed by
ZR: Really? Is that true?
DS: Yes, because most machines had one large drum and the clothes went round and round in it. ZR: So what can you do to improve that? DS: 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 work differently. One drum goes in one direction and the other goes in the other. So it’s more like hand-washing and the clothes come out cleaner. ZR: Was it easy to design?
DS: No. It took many working models before Mr Dyson was content with the result. ZR: How long did it take him? DS: I’m not sure. But I know that when he invented a new carpet cleaner it took five years to design and over 5,000 tests before he was satisfied.
ZR: Wow! I didn’t realize it took so long. DS: Oh, there are more problems even after you get the patent. For example, during the early years James Dyson found that a large company making carpet cleaners in America was
copying his ideas. He had to go to the court to protect his invention. ZR: I hope he won. DS: Yes, in the end that company had to pay us a lot of money because they had used our ideas illegally. It was an important day for us.
ZR: What new ideas does James
Dyson have? DS: I’m sorry but you’ll just have to wait and see! ZR: Thank you and I’m afraid I shall have to ring off now. Goodbye.
3. You want to apply for a job in James Dyson’s company. So you ring up one of his engineers to ask what kind of person he needs. Remember to ask for as much information as you can. Here some phrases that may be useful for you to make a telephone call:
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. Sorry. He / She isn’t here right now. Can I ring back later? I’ll ring him / her up again. I must ring off now because…
(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 take 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
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,
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 new-comers 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. l must ring off now
because I have to go back home for
lunch. Thanks a lot. Bye! E: Goodbye and good luck!
Now write a letter to James Dyson asking him for a job in his company. Here is the beginning and ending:
Dear Mr Dyson, I would like to apply to become an assistant in your company. … I would be grateful if you would consider employing me in your company. Yours sincerely, (your name)
Use the list of skills to make new paragraphs in your letter. ● For each skill set down any experience you have had, which shows that you are a suitable person. You may be creative in this part of the letter. ● Finish the letter by mentioning again the skills that you have.
Dear Mr Dyson, I would like to apply to become an assistant in your company. I expect to get a degree in mechanical engineering from Beijing University at the end of this year. I have always been a good student and last year I finished
third in my year and my professor expects me to do even better in this year’s exams. I have worked (in my holidays) for a company that makes toys for the Western market. I helped in the design department and designed a range of new
panda playing cards and board games. It was fun and made me think that I would like to work in a real inventor’s
I understand that my qualifications and
experience are what you look for in a
