The purpose of my writing this letter is to recommend a book to you.That is Harry Potter,which is one of my favorite books。

　　It is written by J.K.Rollins,who is a famous writer.In fact,Harry Potter contains seven books,and mainly tells the seven years of adventure life story about Harry Potter,who studies at Hogwarts school of witchcraft.To begin with,the life story is very interesting,and I can experience lots of things that I have no chance to experience by reading it What is more,I can learn the spirit of perseverance from him and be strong in face of difficulties.In short,I can benefit greatly from it。

　　I hope you can find my recommendations useful.And I am ready to discuss it further with you。

　　Yours sincerely,

　　Li Ming
