Dear All:
I lost a book at 5 pm on December 29th in room 210 of Wenxin Building. The title of the book is 《Advanced English Grammar》. This book is very important and helpful to me, for I am bad at grammar. The final examination is getting nearer and nearer and I am worried about my English exam very much. Anyone who finds the book please contact Li Ming on 13774336899. I will be very grateful to you and your kindness. I am looking forward to your calls.
