【答案解析】[听力原文]
Do It Yourself Magazine organizes a competition every summer to elect the "Handyman of the year". The winner of this year is Mr. Roy Miller, a Sheffield postman. A journalist and a photographer have come to his house. The journalist is interviewing Mr. Miller for an article in the magazine.
W: Well, I'm very impressed by all the work you've done on your house, Mr. Miller. How long have you been working on it?
M: I first became interested in Do-it-Yourself several years ago. You see, my son Paul is disabled. He's in a wheel-chair and I just had to make alterations to the house. I couldn't afford to pay workmen to do it. I had to learn to do it myself.
W: Had you had any experience in this kind of work? Did you have any practical skills?
M: No. I got a few books from the library but they didn't help very much. So I decided to go to evening classes so that I could learn basic carpentry and electrical wiring.
W: What sort of changes did you make to the house?
M: First of all, practical things to help Paul. You never really realize the problems handicapped people have until it attacks your own family. Most government buildings, for example, have steps up to the door. They don't plan buildings so that disabled people can get in and out. We used to live in a flat, and of course, it was totally unsuitable. Just imagine the problems a disabled person would have in your house. We needed a larger house with wide corridors so that Paul could get from one room to another. We didn't have much money and we had to buy this one. It's over ninety years old and it was in a very bad state of repair.
W: Where did you begin?
M: The electrical. I completely rewired the house so that Paul could reach all the switches. I had to lower the light switches and raise the powerpoints. I went on to do the whole house so that Paul could reach things and go where he needed.
W: What else did you do?
M: By the time I'd altered everything for Paul, do-it-yourself had become a hobby. I really enjoyed doing things with my hands. Look, I even installed smoke-alarms.
W: What was the purpose of that?
M: I was very worded about fire. You see, Paul can't move very fast. I fitted them so that we would have plenty of warning if there were a fire. I put in a complete burglar-alarm system. It took weeks. The front door opens automatically, and I'm going to put a device on Paul's wheelchair so that he'll be able to open and close it when he wants.
W: What are you working on now?
M: I've just finished the kitchen. I've designed it so that he can reach everything. Now I'm building an extension so that Paul will have a large room on the ground floor where he can work.
W: There's a $10,000 prize. How are you going to spend it?
M: I am going to start my own business so that I can convert ordinary houses for disabled people. I think I've become an expert on the subject.
