在一个宁静的小村庄里，住着一位善良的老奶奶和她的小孙子汤姆。一天，汤姆问奶奶：“奶奶，为什么我们总是要帮助别人呢？”

奶奶微笑着回答说：“因为这个世界就像一棵大树，每个人都是树上的叶子。如果一片叶子枯萎了，整棵树都会受到影响。”

汤姆似懂非懂地点点头。不久后，他看到邻居家的小狗受伤了，便主动把小狗抱回家照顾。几天后，小狗恢复了健康，邻居非常感激。

这个小故事告诉我们，帮助他人不仅能让他们感到温暖，也能让我们自己变得更加善良和快乐。

A Simple English Story with Translation

In a quiet village, there lived an old grandmother and her little grandson Tom. One day, Tom asked his grandmother, "Grandma, why do we always have to help others?"

The grandmother smiled and replied, "Because the world is like a big tree, and everyone is a leaf on it. If one leaf withers, the whole tree will be affected."

Tom nodded, not fully understanding. Not long after, he saw a neighbor's dog injured and took the dog home to take care of it. A few days later, the dog recovered, and the neighbor was very grateful.

This short story tells us that helping others not only makes them feel warm but also allows us to become kinder and happier ourselves.
