【答案解析】[参考范文] One day a famous writer was on the way home when he found a crowd of people standing by the river. He wondered what had happened there. So he went over. He was told that just a moment before a rich man had fallen into the river, a poor peasant jumped into it without de lay. The rich man was saved but he didn't thank the poor peasant for his help. Finally as the rich man was afraid of being scolded (责骂) by the people around, he rewarded the person with only a coin for having saved him in time. Once hearing the story, the famous writer said to the crowd, "Let him be. Only he himself understands that his life is worthy of nothing but a coin."
