听力原文：W: Well, Charles, I must say that your shop is pretty remarkable. [7]Urn, it's basically a sweetshop, but you also do stationery, greeting cards, tobacco and fireworks...
M: And newspapers.
W: And newspapers. Ah. And apart from all that, you've got photocopiers...
M: That's right.
W: And a fax machine.
M: Indeed.
W: Yes. How did... I mean, why the photocopiers？
M: Everything that's happened in my shop has almost happened by accident. [9]But when I got into Clifton, I needed a photocopy one day and no one could tell me where to go. So it struck me that if I didn't know where to go, other people were in the same situation, so that's why I started it. And then I added on a facsimile machine because it seemed like a natural progression at the time. And all sorts of people use it.
W: Yes, who, what sort of people do use it？
M: [10] Um, a lot of professional people—surveyors, engineers—particularly people who need to send, plans. [8] Because in the past you could send messages via telex, but a telex can't express a plan, whereas facsimile has that dimension, the added dimension.
W: Right. And do people send these fax messages abroad, or is it just to this country？
M: Well, it's surprising because when I started, I thought I'd be sending things to London and maybe Birmingham, [9] but in fact, a high percentage of it is sent abroad, because it's immediate, it's very speedy.
