a story

Last  Saturday ,I  went  to  visit  the  Great  Wall  along  with  our  foreign  teacher ,Mr. Brown.The  Great  Wall  is  grand  with  a  long  history ,we  absorbed  in  enjoying  the scenery .Mr.Brown  had a desire to  take  some  photos  in  order to record  the tour  and  he put  his  bag  on the ground  putting  an interesting  pose.After for  a  while,we  came to another  place  where  an  activity  about   protecting environment  was  being  held.Mr.Brown  was  excited  about  it and  was eager  to  join  it ,completely  not  knowing  his  bag  lost.However,as  the  old saying  goes,Good-heartedness often meets with recompense.A young  girl  appearing  to  be a student  picked up  the bag  and  return  it without  saying  anything. We all  very  thanked  the  kind  girl .If  everybody can  like the girl  ,our  society  will  become better and better.
