　　Dear Bob，

　　I'm sorry to tell you that I cannot go to the bookstore with you on this Sunday，because something unlucky occurred to me in the PE class yesterday．

　　I was playing basketball with my friends while I jumped highly to catch the ball．Another student struck me on a leg accidentally，that made me break my leg．The situation made everyone nervous．However，I was sent to the nearest hospital as soon as possible．The doctor suggested that I rested until next Friday．I hope the change will not cause you too much troubles．

　　Shall I go on next Saturday morning？We can set out early so that we'll have more time read and select books．

　　Yours，

　　Li Hua
