Y: Hello. I'd like to change my reservation for March 19. My name is Mary Chang.
X: Ah, yes, Miss Chang. What seems to be the problem?
Y: Well, I'd like to change the date to March 20, and make that for two singles, not one.
X: Very well. That can be arranged.
Y:哈啰,我想更改预订在三月十九日来住的房间。我叫张玛莉。
X:哦,张小姐。有什么问题吗?
Y:我想把三月十九日改为三月二十日,并且要二间单人房,而不是一间。
X:没问题,这件事就交给我办好了。
