W：Officer, officer, I have something important to report. I have just had my money stolen! M：Before you begin , why not take a seat and calm down a little? Don't be too excited. It won' t help us catch the thief. W：Yes, you are completely right. Where should I start? M：At the beginning. When did it take place? W：About ten minutes ago. M：And where exactly was this? W：It was probably on the moving stair coming up from the underground at Xi' an. I think somebody had been following me from the time I left the bank. M：The bank? W：Well, you see, I went to a bank to exchange some traveler's cheques for money, so I can buy my airline ticket back home. M：Yes, yes. How much did you exchange? W：About 4,500 dollars worth. M：And how much was stolen? W：All of it. M：I see.
