Leaders, Members:
My name is Liyuanyuan. Im a boy and I am 12 yeas old, there are 4 people in my family. My father is a Chemistry teacher. He teaches chemistry in Zhengxin senior high school.
My mother is a Chinese teacher. She teaches Chinese in the university. I have an elder brother; he is a junior middle school student and is preparing for the entrance exam.
Im tall and I have a pair of big eyes. Now, I am in Grade 5, my study is not very good, but I like English, so my English is better than others.
I like singing, drawing, playing basketball. I like to read English story books in my free time. Sometimes I surf the Internet and download the English study materials. Because it also enlarges my vocabulary words. I think one day I can master English. Thank you.
