用英语介绍一本书
《哈利波特》：
My favourite book and I enjoy reading different kinds of books, but "Harry Porter" is my favorite one. The story is very long but I am interested in it. Harry was such a brave and clever boy that he dared to fight against powerful enemies.
His Z-shaped scar and magic stick brought me into a magical world. In fact, the fiction story is so meaningful that I can learn a lot from it. I think it's the best book I've ever read.
