听力原文：M: I just put a brand new battery in your camera, but it's not working. I think it may be broken. W: Yeah, it's about time. That camera is over 20 years old. My father gave it to me when I got into college. Oh well, it's just as well because I have been thinking about getting a digital camera for some time now. M: Really? My brother works at a camera shop. If you'd like, I can call him up and see if he can give you a deal. Roughly how much are you thinking of spending? W: I was looking at around 300 dollars. I can't afford to get anything too fancy but just something that takes reasonable pictures so that I can take shots when I travel. Why is the camera not working?
