Do you know Harry Potter？It's my favorite spare time reading and it's written by J.K.Rowling.
Harry Potter is a magical school student who wears glasses and has no parents, and now he is 16 years old. He is very brave and known by everyone because it is said that he is the only person that will not be killed by the evil.
When I read the book for the first time, I thought it was very exciting and interesting. So I read it again and again. Each time范文:I have different feelings. Books about Harry Potter have been sold millions of copies all over the world. Do you like Harry Potter？If you haven't read the book yet, read it now and you'll find a wonderful world.
