     Harry Potter is a set of popular books created by J.K.Rowling in Britain. The books tell us some

unhappy life. However, a strange letter changed everything. It said he was accepted by Hogwart's a
magic school which was closed to the common people. All kinds of adventures (冒险) happened to
Harry from then on. He met Ron Weasley and Hermione Granger on his way to school. They became
good friends later. Harry did well in his lessons and worked hard to play magic. Harry always had a
