My friend Lilly and I were on the way back to home from school when we saw a boy fall off his bicycles. The boy lay on the ground， screamed in pain. We rushed to help and found if the boy's left leg was bleeding. It happened that we have learned some knowledge about first aid before， so we knew how we should do. We dialed "120" and called an ambulance. While waiting it， I took out my handkerchief and pressed them onto the bleeding point. Then we rolled the boy onto one side but put him in the recovery position. We stayed with him until the ambulance arrived 5 minutes late.

I have recently been told that listen to loud music is gradually making people hard of hearing. I'm sure it has already been happened to my neighbor. For years she had turned a deaf ear to my requests to turn her radio down. When she gives a party she doesn’t have to invite a rest of the street. Everyone can dance in her music in his own room. Now a scientist has discovered certain electronic sounds have strangely effects on rats. He declares break down, almost paralyze(瘫) with their legs trembled. Then it is simply a matter of throwing them out by their tail. I wonder that the same thing will happen to my neighbor someday.

When I was little, Friday’s night was our family game night. After supper, we would play card games of all sorts in the sitting room. As the kid, I loved to watch the cartoons, but no matter how many times I asked to watch them, my parents would not to let me. They would say to me that playing card games would help my brain. Still I unwilling to play the games with them sometimes. I don’t realize how right my parents were until I entered high school. The games my parents taught me when I was a child turned out to be very useful later in my life.
