|Have you gone wi-fi?|
Jo: This is Real English from BBC Learning English. I’m Jo.
Jean: And I’m Jean. (来源：EnglishCN.com)
Jo: Today we’re going to look at words and phrases that have recently become part of the English language.
Jo: It’s very important to stay up-to-date with English because new words and expressions enter the language all the time.
Jo: Today’s expression is 'wi-fi' – W.I. and F.I. Wi-fi.
Jean: Wi-fi. Wi-fi 是什么东西呢？
Jo: Well, Wi-fi is short for wireless fidelity. It means that instead of using wires, your computer is connected to the internet or other computers by radio.
Jean: 原来 wi-fi 就是一种不需要把电脑连在传统的线路上，就能直接快速上网的无线技术。
Jo: That’s right. You could say 'I work in a very modern office. Everything’s wi-fi.'
Jean: I see.
A: Where do I put this wire to connect to the internet?
B: Don’t be silly! This computer is wi-fi! You don’t need any wires!
Jo: Is your office wi-fi, Jean?
Jean: No, it isn’t.
Jo: Neither is mine. We have wires going everywhere.
Jo: Yes. However, the boss says we may go wi-fi next year.
Jean: Is it expensive?
Jo: Of course wi-fi is more expensive, but it’s getting more common now.
Jean: Is it in the UK?
Jo: Yes, all new computers are wi-fi these days.
Jean: 好，今天我们学到的新词汇就是 wi-fi，就是一种不需要把电脑连在传统的线路上，就能直接快速上网的无线技术。And we have to go now.
Jo: Yes, that’s all for today. You’ve been listening to Real English and this is BBC Learning English. Join us again soon for more up-to-the-minute Real English. Bye.
Jean: See you next time.
