One possible version:
My name is Tian Tian. I’m in Class 4, Grade 9. I’m very brave, outgoing and easygoing. And I am helpful. I like traveling and making friends a lot. My favorite sport is basketball and I am very good at it. I enjoy reading English novels well. In 2012 I won the first price in the school English competition. Xuzhou is my hometown. It is a beautiful and clean city. There are many places of interest. I love it and I know it very well.
I really want to be a student guide for the American friends. I’d like to show them around our school and visit Xuzhou.
