听力原文：M: Did you watch television last night? W: No, I didn't. I seldom watch it anymore. M: Why is that? W: There are only a few programs that I find interesting enough to watch. M: Well, there are some shows that I never miss. Don't you ever watch star trek? W: Yes, I watch it now and then but it isn't something I can't live without. M: I' m a big fan of star trek. I love the characters and the idea of traveling through the universe at speeds faster than light is fascinating to me. I really like all the different life forms that they create, too. W: I know all about fans like you. I think they call you 'trekkies'. Is that right? M: Yeah, that's what they call us. W: I know there are some good shows on TV, but there is so much violence on so many of the shows. A person could witness more killings in one night that a soldier would encounter in months of warfare! M: I agree with you there. However, there are some shows that I never miss. (20)
