假定你是初三(1)班的李霞，你五月十四日晚上在阅览室里丢失了一个绿色书包，内有两本英语书，一个铅笔盒，一个MP3及自行车钥匙。你非常着急。你根据以上提示，用英语写一则5 O词左右的寻物启事。
Found
I left a green school bag in the reading-room on the evening of May 14. There are two English books, a pencil-box, an MP3 player and the key to the bike in it. Now I'm very worried about it. Will the finder return it to Li Xia of Class 1, Grade 3? Thanks a lot!
