Dear editor，
I am writing to tell you a piece of original information. I picked up a passport last Sunday in the subway station when I was taking a ride home. There was nobody around when I found it on a waiting bench. The owner of it is Stephen who comes from England. I think he must be feeling anxious about the passport, but I have no idea how to return it to him.
So I need your help. I wish you could post a notice on your newspaper to tell him about missing passport, so that he can get it back. I would appreciate it if you could do me the favor.
I am looking forward to your reply.
Yours,
