| Is the art of conversation dying? The other day, my wife 1 two teenage children did something we haven't 2 for ages. It didn't require the Internet, a TV screen, batteries… or anything else for that  matter. But we all 3 it so much we're thinking of doing it again sometime.We had a conversation. The kind of real, live conversation that was 4 when I was growing up, but which seems all too rare these days. Today we have chat rooms, text messages, e-mails but we seem to be losing the 5 of communicating face-to-face. We all know 6 young people are out on a date(约会)these days, they spend most of that time 7 their mobile phones. And teenagers nowadays seem to 8 communicating with their friends by sending text messages rather than actually 9 to them. If we carry on like this,in the future, we'll lose the use of our 10 . What do you think? E-mail me, and who knows? Maybe we could even have a real conversation about it! | ||||
