An Unforgettable Story
It happened six years ago.On a summer vacation,my father took me to Beijing.In the morning,we went to the Great Wall and the Summer Palace.I was very happy.And then in the afternoon,we went shopping.But the shops were too crowded.After I had fun seeing the toys,I couldn't find my father!I was very sad and cried loudly.A policeman saw me and asked me what happened.I told him.Then he took me to the police station.Half an hour later,my father came.I was so happy that I cried again.From then on,I always followed my father or mother when we went shopping,because I was afraid of being lost again.
