My name is Li Hua. I'm thirteen. I'm a middle school student. I'm in Class Five, Grade Seven. My English teacher is Mr. Lin. He is an old teacher. I have(有) a pen, a ruler and two pencils. I have a bike, too. Liu Ping is in my class. She is a girl. We are good friends. She is not at school today. I think she is at home(在家). Look! Here is a book. But it's not my book. I think it's Liu Ping's book.
