A、Workers. B、Students. C、Engineers. D、Businessmen. B身份题，对话所讨论的是校园网络。很明显双方都是学生。

M: What do you think of the campus Network?
W: I think it still needs further improvements; it was only set up a few months ago.
M: I think it’s a fantastic idea to have every department’s computers connected. But it’s a pity you can only access the China Education and Research Network within the campus Network. You can’t visit some domestic websites, not to mention the international ones.
W: You are right. But with your own desktop and a modem, you won’t have this problem.
M: Then you will have another problem. The connection speed sometimes slows to a trickle and it really puts users in a pickle.
W: Come on, you have to face it, the number of netizens, I mean, the Internet surfers, is growing so fast in China. There is good news, though. Some telecom departments have started increasing the bandwidth of Internet connection, so the transmission is expected to speed up at the end of this year.
M: Wow, I think it’s not only good news for the average Internet surfer, but also wonderful for online education in China.
W: Yeah, with online education, the long-distance education in China will expand a lot. Students, used to studying radio or television programs, now can have another alternative.
M: For many people who can not study on a fixed schedule, online education should suit them best.
W: Oh, sure. Online education gives students enough flexibility, and what’s more important, their studies are entirely interactive. You turn in your homework and then get the teacher’s comments in no time.
M: I hope China can set up more net colleges; anyone who can not study in a traditional college can thus have access to higher education.
W: It’s not a hope but already reality now. That’s why some people say the Internet is an equalizer. It allows people access information more readily, thus narrowing the gap between the haves and the have nots.
