Yesterday when my son and I were eating dinner, I saw a policewoman walking past our house. A woman with a   36   look was following her.
I opened the 37 , went out and asked if everything was OK. The policewoman said that the woman's 38  had gone missing(失踪) an hour earlier. I said that we hadn't seen the girl, but wecould 39 .1 explained to my son that we couldn't finish our 40 right then. He said,” Be a kind person, Dad. "We got in our car and 41 the girl all over the town. Along the way,a group of children were playing. 42 they heard what had happened, they said they would help 43 . They rode their bikes and joined us.
44the little girl was found safe a few miles away. I was so 45  to see many people help a stranger. It is a nice world.
