Hello, everyone! My name is xxx, I'm xx years old. I'm （a）sunny girl. I like to help people (who are) in need of help. I'm very happy that I can study in xxx experimental school, also can (meet) everybody and study together here in xx class. My hobby is painting and photography. (I hope to be one of your friends. Also, I want to study well and to gain good grades in the middle school period. I hope that you will help me. Thank you!)
