Hi, I'm Bill. I'm twelve years old. I'm tall and strong. I like playing basketball. I like blue. I like spring best because there are beautiful flowers everywhere. I like to read storybooks. But three years ago, I was short and thin. I couldn't ride my bike or play basketball. I wasn't good at English. Then I changed a lot. Now I can ride my bike well. I play basketball every day. And now I can play basketball well. I often play basketball with my friends after class. I also do well in English. This makes me very happy. I think I can do many things. I'm a big boy now. What about you?Tell me your changes.
