如何获得叫醒服务

Clerk: What can I do for you, sir?
Tom: I'm Tom in Room 528, and I want a wake-up call tomorrow morning.
Clerk: At what time?
Tom: 6:15am please.
Clerk: We have a computer wake-up service. Please dial 2 first and then the time. That is to     say, dial 2 and the 0615 for the time. There must be five digits in the final number.
Tom: I see. Then it is 20615. Thank you. By the way, if I want to change my wake-up time, what    should I do?
Clerk: Just dial your new wake-up time. The computer will automatically cancel the old time      and record the new one.
Tom: If I dial 20700, I will be waked up at 7:00 am?
Clerk: Yes, that's right.
Tom: Thanks a lot.
Clerk: You are welcome. Good night!

服务员:有什么为您效劳的吗,先生?
汤姆:我是528房间的汤姆,请明早叫醒我。
服务员:什么时间?
汤姆:6:15
服务员:我们有电脑叫醒服务。请先拨2,再拨时间。也就是说,先拨2,再拨0615。最后必须有5位数字。
汤姆:我明白了。也就是20615。谢谢。顺便问一下,我想改变叫醒时间该怎么办呢?
服务员:拨上新时间即可。电脑将自动取消原先的叫醒时间并记录下新时间。
汤姆:如果我拨20700,就会在早上7:00叫醒我,是吗?
服务员:是的。
汤姆:非常感谢。
服务员:不客气。晚安!
