A man got a new car and he was very proud 　26　 it. One day, when he 　27　 back home, he saw his three-year-old son 　28　 hitting the new car with a toy hammer. The man was 　29　 angry that he ran to his son, grabbed the hammer from 　30　, and used the hammer to hit the little boy’s hands too hard. The 　31　 boy cried out but his father didn’t care.
When the father 　32　, he took his son to the 　33　 as fast as he could. Although the doctor tried his best to save the 　34　 bones（骨头）, he had to cut the fingers from both of the boy’s hands in the end.
When the boy 　35　 in the hospital and saw his hands, he innocently(天真) said, “Dady, I’m sorry about your car.” Then he asked, “but 　36　 are my fingers going to grow back?” The father 　37　 very sad.
Think about the story when 　38　 steps on your feet or when you wish to take revenge(报复). Think first before you lose your patience with someone. Cars can 　39　, but broken bones and hurt feelings often can’t.
　　People often make mistakes. But we should remember that forgiveness is greater than revenge. 　40　 before act!
