Last Sunday afternoon, I went to the zoo with Lily. There was lots of people there. I found a girl cry in the zoo. She was lost and she can't find her mother. We decided to help him. I tried my best find the broadcasting station in the zoo. On the same time Lily played with her and looked after her careful there. The little girl stopped crying and played with Lily. At last her mother came, that made me feel very happily. I thought I really did a good thing. If everyone helps with each other, the world will become more beautiful.
