An old bike.  It's black with a plastic(塑料的)basket.  Its seat is yellow.  If you find it, please return it to me.  I live in the fifth floor in Building 2.

    Miller   Lost

Yesterday, I lost a novel written by Mo Yan.  Its name is Frog.  I’m eager(渴望的)to find it.  If you find it somewhere, can you return it to me? I’m from Class 6, Grade 7.
