What is true friendship? I think it is a great shareable emotion between you and your friends. You share his happiness when your friend gets good marks in the exam. You share his sadness when he is unhappy.

Of course the most important thing for true friends is that you can help each other. When you meet troubles, he or she will try their best to help you at once. When your friend is in danger, you will be happy because of your friend's sadness. I think this is true friendship.

【参考译文】

什么是真正的友谊呢?我认为友谊是朋友之间最伟大的一种感情共鸣。当你的朋友考试取得了好成绩，你能够分享他的快乐;当他伤心时，你能够分担他的痛苦。

当然真正的朋友之间最重要的是能够互相帮助。当你遇到困难时，他或她立刻竭尽全力帮助你;当你的朋友遇到危险时，你会立刻去救他或她。

总之，你会因朋友的快乐而快乐，因朋友的悲伤而悲伤。我想这才是真正的友谊。
