高中英语作文 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.
