Michael和李华正在尽情享受这星期才开始的假期。今天他们去参加了一个音乐会。

L: Michael，这音乐会真不错，就是太长了。我啊快要饿死了！快去找个地方吃东西吧！

M: Alright. There's a cafe on the corner over there, I think it's open 24-7.

L: 对，前面就有家咖啡馆。你说那个cafe 24-7, 24-7是什么意思呀？

M: I said it's open 24-7. You know the number 24, and seven, right? 24-7 means it is open all the time.

L: 我知道了！就是说一天二十四小时，一个星期七天它都开门。对不对？

M: You've got it! In the U.S. a lot of small diners, convenience stores and gas stations are open 24-7.

L: 对，我看到一些小饭馆，还有一些杂货店还有加油站，他们都是二十四小时营业的。Michael, 那24-7是不是只能用在商店哪？

M: Not at all! It can be used for anything. For instance, Li Hua, if you ever have an emergency, you can call me any time, 24-7.

L: 噢，24-7可以用在任何场合。你说要是我遇到紧急情况，可以在任何时候打电话给你。Michael, 你真是太好了。不过，我想我可能会先打911。

M: Yeah, that's probably a better idea. 911 operates 24-7. Li Hua, can you use this phrase now?

L: 让我想想。有了。期终考试前，我肯定很多人为了准备考试，交报告晚上开夜车，所以可以说：Many students worked 24-7 before the finals. 对不对？更多信息请访问：http://www.engbus.cn/

M: You're right. I was also up 24-7 studying and writing before the finals.

L: 那最后一个礼拜真够呛。现在总算轻松了。

M: That's right! Woo Hoo! Hey, after we eat, let's go dancing somewhere.

L: Michael，你还没有玩够呀！

M: Now that we are on vacation, I'm ready to party 24-7!
