AIRPORT BUS

laurance--What time doesd the bus leave for the airport?
soony--I don't know.It used to leave every half hour,but
       I think the schedule's been changed.
laurance--Do you know the telephone number to call?
soony--It's Enterprise 7--4700.At least that's what it
       used to be.
laurance--Yeah,I'll try it.(PAUSE)They don't seem to
          answer.
soony--I expect that it's a little too-early.I don't
       think they open until nine o'clock.

every half hour:是每隔半小时,类似的短语还有:every other day/
                every three weeks/every twenty days
Enterprise 7-4700:是较旧的电话系统.电话机上除标有数码外还有英语字母.
                  所以拨EN7-4700即可.
