听力原文：W: How are you doing? You look tired. M: I'm a little burnt out. I've been surfing the Net for the last few hours. W: Were you doing schoolwork, or was it just for pleasure? M: Well, I wanted to get some information on South America for a project I have, but I found a really interesting chat site with people from there and started chatting. W: Well, did you get the information you needed? M: Yes, but then we spent lots of time chatting about other interests. W: I see. The Internet is a wonderful place. There is so much information available. I completely understand how you can get distracted. Sometimes I find myself looking for one piece of information, but by the time I am finished I have a lot more than I started off looking for. M: I know. One thing I really don't like about it, though, is it takes so much longer to find things, because many sites are useless. W: Yes, there's that, and also, I often find the same site over and over again in a search. That definitely wastes lots of my time. M: Of course, there are sites that offer little to no relevant information on the topic you are searching for. With all the time I spend on it, I still find it to be the best source of information available. And speaking of information, I really should read through what I got on the Internet and start working on my project. W: Okay. Good luck. It's funny we had this chat, as I was just on my way ho: he to surf the Net myself. M: Well, it was nice talking to you, and maybe I'll meet you in a chat room later tonight. (20)
