听力原文：M: I was just reading this article about the wonders of the ancient world. A lot of them were buildings. I was thinking, what would your wonders of the modern would be？ Not necessarily buildings, but things that have changed our way of life.
W: For me, well, I was thinking the cell phone is the most wonderful thing.
M: Really？
W: Yeah, (19) I even couldn't live without mine. It's so convenient! I can call my friends anytime and they can always call me. Or if I'm in trouble I can call for help...
M: You mean like calling your parents？

M: (20) But the problem with cell phones is that people use them too much for every little thing. It's practically glued to their ears.
W: Yeah, and I hate it when people shout into them in a public place and everyone else has to listen to the conversation, especially in restaurants.
M: Well, good manners aren't a wonder of our world! You know, I think the most amazing wonder is e-mail. It has changed the world, and it has totally transformed my business. Everybody at work is always on the computer, responding to e-mails, sending e-mails... That's where most of our business is done now, through e-mail. You are sending reports, getting information. But the bad part is that you are glued to the computer and people expect things to be done right away.
W: Yeah, people are shocked if you go through a day without checking your e-mail. And when you go on vacation and then you come back, maybe there are 200 e-mails waiting for you — all of them urgent.
M: I guess it is like any other tool or device. (21) If it's used correctly, it's very useful.
