托福口语问题,TASK1,请帮我写一段关于 many students do volunteer work,问what kind of volunteer do?

Among the various volunteer work students do,I perfer helping children in the orphange house the most.
there are several reasons.
1.the children in the orphange house are teenagers just like me.we understand each other,so we can share our favorit books,talk about the NBA players and listen to pop music.they are just my friends and i am quite happy hanging out with my friends.
2.While I care about them,they care about me.They made me little gifts for me at my birthday.No matter how busy I am,I always want to visit them to see if they are living well; nevertheless,they miss me very much if I don't come to see them for a period of time.
3.we always say that to give is to bring happiness to yourself as well as others.Seeing the children in the orphange house happy,I feel that this volunteer work is so rewarding that I am happy with these children I help.
