A RAVEN saw a Swan and desired to secure for himself the same beautiful plumage.

Supposing that the Swan's splendid white color arose from his washing in the water in which he swam, the Raven left the altars in the neighborhood where he picked up his living, and took up residence in the lakes and pools.

But cleansing his feathers as often as he would, he could not change their color, while through want of food he perished.

Change of habit cannot alter Nature.

乌鸦非常羡慕天鹅洁白的羽毛。

他猜想天鹅一定是经常洗澡，羽毛才变得如此洁白无瑕。

于是，他毅然离开了他赖以生存的祭坛，来到江湖边。

他天天洗刷自己的羽毛，不但一点都没洗白，反而因缺少食物饥饿而死。

这故事是说，人的本性不会随着生活方式的改变而改变。
