At the aquarium, I saw a small fish swimming close to a much larger one. The larger fish stayed almost still while the small fish picked tiny things from its skin. For a moment, I thought the small fish was attacking it.
The sign explained that it was a cleaner fish. It can eat parasites from other fish. The small fish gets food, and the larger fish may lose unwanted guests from its body.
I watched again. The larger fish did not swim away. That did not mean every meeting between fish was friendly, but this one made more sense after I read the sign. The same movement had looked like an attack before I knew what both animals might gain.

读懂了什么？
读完后，试着用一句话说出本文的主要意思，并从原文找出支持它的一句话。
查看中文译文
在水族馆，我看到一条小鱼游到一条大鱼身旁。大鱼几乎一动不动，小鱼从它的皮肤上啄下一些细小的东西。一开始，我以为小鱼在攻击它。
说明牌告诉我，这是一种清洁鱼。它可以吃掉其他鱼身上的寄生虫。小鱼得到了食物，大鱼则可能摆脱身上的不速之客。
我又看了一会儿。大鱼没有游开。当然，这不代表鱼儿每一次靠近都是友好的；但读过说明牌后，眼前这一次互动就更容易理解了。原来，知道双方可能得到什么，会改变我对同一个动作的看法。
