听力原文：W: Hi, Mark, I didn't know you could paint. M: Well, I'm just learning. It's for my studio art one of one class. W: It's pretty good for a beginner. M: Oh thanks, Judy. The instructor really liked my schedules, but she hasn't seen my painting yet. W: En, there seems to be something wrong with it though. M: Yeah, I know what you mean. It doesn't look like to me either. W: I think I know, look here at the sky, it just seems to filled in with other colors of paining. M: What do you mean? Everyone knows the sky is blue. W: Well, that depends. Sometime it is and sometime it isn't, as sunset can be full of reds and purples. Well, even now, look at now Mark, what do you see? M: It looks blue to me. W: Look again. Do you see a kind of tallish color? M: Oh yeah, I see what you mean. W: By adding some tan to your sky, I think you'll get more actual picture, and the color will look more natural. M: I think I'll try that. Gee, how do you get to know so much about paining? Have you taken a lot of courses? W: No, actually. But my father is an artist. M: A professional artist? W: Oh yeah. He shows his staff in lots of exhibits, everything is when we were kids he always talks to us about his work. M: I wish we could talk some more Judy. How about going for a cup of coffee? I'm ready for a break. W: I'd love to, but I have to study for a history exam. In fact, I was just on my way to the study group, and I think I am already late. Maybe tomorrow? M: Great, I'll meet you at the students' center after my class. A little after three, OK? W: Sounds good. Get around now. M: Bye, Judy. What is the man doing?
