听力原文：W: Welcome to visit our city, Mr. Lewis -- but, of course, you have been here before, haven't you? M: Yes, I have, what a good memory you have! I was here for the Arts Festival last year. W: And what will you be doing on this visit? M: Oh, I came here primarily for a holiday and to see some friends. But I will also be giving some private cello lessons as well. W: I believe that your cello is rather special. Is that true? M: Oh, yes. It was made for my uncle by a very expert German cello maker called Schuster. When I began, cello lessons at the age of eight, he said that when I grew big enough to handle a full-sized cello, he would give it to me. W: So when a child begins to play the cello, he or she starts on a smaller instrument? M: Of course, or he would be very uncomfortable. Many children begin with a half-sized cello, but as I was big for my age, I began with a two-thirds-sized cello. W: Are you going to other places on this trip and will you take your cello with you? M: Yes, very definitely. W: But, isn't it difficult taking a cello around with you? M: Not really. I just reserve two seats when I'm traveling anywhere, one for me and one for my cello. It's such a precious instrument to me that it hardly ever leaves my side. (20)
