Yesterday afternoon I was walking home by the river from school and there were few people in the street for it's late in the ecening.Suddenly,a woman walked forward a young man and begged him to save her son who fell into the river just now.The young man run to the edge of the river and jumped into the river and got hold of the boy and then successfully saved the boy.Following,the woman and her son were thankful to the young man.希望能帮助你!!!
