注意：词数80左右。
I am Li Hua，a sixteen-year-old boy. My friends think that I am outgoing
and they like to hang out with me in their spare time. Playing basketball and
swimming are my hobbies. At school,I always study hard and like discussing
problems with my classmates. My favorite subject is physics because I find
physical experiments very interesting and some problems in physics develop my
thinking. I wish to become a scientist in the future.
谢谢
