听力原文:M: Did you take these pictures? They are very good.
W: Yes, I think they turned out very well too. I like to bring my camera with me wherever I go. That's way if I see something attractive I can take a picture of it.
M: Carrying a big camera around is too much trouble for me.
W: My camera is really small enough. Here let me show you.
M: That is a compact camera. But you must know a lot about photography to get such professional looking results.
W: Not necessarily. This camera is simple to work. It has an automatic focus. I don't even have to worry about focusing.
