Dialoge A
Mr. Smith: At first glance, a metro is just like a train that runs through a tunnel, is it right? Lily: Yes, you are right. Actually it consists of many parts. Mr. Smith: I see. There are some seats, poles and straps inside a metro train, and some information boards and signs, entrances and exits in a metro station. Lily: Do you see Platform Screen Door (PSD), escalators, elevators, Automatic Gate Machine (AGM) and the Ticket Vending Machine (TVM) on this station? Mr. Smith: Yes, I see them. Can you tell me what‟s the function of a Automatic Gate Machine? Lily: Well, Just put your ticket here and then the gate will open after a „beep‟ sound. Go through it and you can get in to take the train. Mr. Smith: It‟s an amazing machine, isn‟t it? Lily: Yes, absolutely.
