Tom is a son of a farm owner. One New Year’s Day, when he was 15,his father asked him on the farm for one year when he was free. Tom was with his father’s idea. “ That isn’t my job. I have school work to do.” Hearing this , his father said,” I promise to give you the best present if you finish one year’s work.” Tom thought for a while and . Starting one Saturday, the boy got up early and worked hard until evening ,just like famers.Time passed quickly. Tom’s crops(庄稼)grew well. the last day of the year, the father called his son to him.“I’m happy to see that you have worked very hard year,”said his father.” Now tell me you want.” The boy smiled and showed his father a big piece of bread made from his wheat. “I’ve already got the best present: No pains, No gains. I think this is what you wanted me to know.” His father was to hear that.
