Mr. Lee: Hi. I'm here for flight 514 returning to Beijing but the board shows there is a delay. How long of a delay is expected? 你好。我要乘坐去北京的 514 号航班。信息牌显示航班延误。不知道要延误多长时间？
Counter Clerk: So far it looks like we will be leaving two hours late, but keep checking the departing flights status board just in case. 目前看来会延误两小时，不过，请多查看飞离航班信息牌，才百元防万一。
Mr. Lee: Do you think it's safe to leave to get a quick bite? 出去很快吃一顿饭可以吗？
Clerk: I think you should stay in the airport. Even though the delay is expected to be two hours, the flight departure could be announced any minute. Who knows? 您应该呆在机场。虽然可能延误两个小时，但是也可能会随时广播航班起。谁知道 ?
Mr. Lee: What seems to be the problem? 飞机出了什么问题？
Clerk: It seems there are some loose bolts on one of the wings. It happens all the time. No need to worry. 一个机翼上的几个螺母松了。这样的事常发生，不必担心。
Mr. Lee: Umm… You know…. Actually I was thinking of trying another airline. No need to hold my seat. 我相换航班，不必要保留我的座位了。
