One day, when l was walking down the street. I happened to find a small wallet 1 there. I 2 and opened it to see if I could find out the owner's name. There was 3 inside except a little money and an old photo--a picture of a woman and a girl about sixteen years old. The young one 4 the woman's daughter. l put the photo back and 5 the wallet to the police station. I handed the wallet to a policeman.
That evening I went to 6 with my aunt and uncle. They also invited a young woman. So there were 7 people at table. Her face was familiar. I was quite sure that we had met before, but I couldn't remember where I had seen her. 8 the talk, the young woman happened to mention(提及) that she had lost her wallet that afternoon. Suddenly I knew where I had seen her. She was the mother of the young girl 9. She was very 10, of course, when l was able to tell her about her wallet.
