That's wonderful! M: I became interested in DIY several years ago. You see, my son Thomas is disabled. He's in a wheel chair and I just had to make alternations to the house. I couldn't afford to pay workmen to do it. I have to learn to do it myself. W: Had you had any experience of 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. Then I decided to go to evening classes so that I could learn basic carpentry and electrics. W: What sort of changes did you make to the house? M: First of all, practical things to help Thomas. You never really realize the problems handicapped people have until it affects your own family. We used to live in a flat and it was totally unsuitable. Just imagine the problems a disabled person would have in your house. We needed a large house with wide corridors so that Thomas could get from one room to another. We didn't have much money and we had to buy this one. It's over 90 years old and it was in a very bad state of repair. W: Where did you begin? M: The electrics. I completely rewired the house so that Thomas could reach all the switches. I had to lower the light switches. W: What else did you do? M: By the time I altered everything for Thomas, DIY 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 worried about the fire. You see, Thomas cannot move very quickly. I fitted them so that we could have plenty of warning if there were a fire. I put in a completer burglar alarm system. It took weeks. The front door opens automatically, and I'm going to put a device on Thomas'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 he will have a large room on the ground floor where he can work. W: Here's a 10,000-pound prize. How are you going to spend it? M: I'm 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. Questions： 1.
