一只乌鸦非常妒忌白天鹅那美丽的羽翼，以为那一身漂亮的白色羽毛是由于经常在水中游泳和洗浴而得来的。于是，乌鸦便离开了靠着肉类祭祀品而赖以谋生的祭坛，前往池塘和溪流中居住。可是，旱管他日日勤于在水中梳洗自己的羽毛，却总也不能使其变成白色，反而因忍饥挨饿而死去。

【乌鸦和天鹅的英文版】
THE CROW AND THE SWAN
A Crow was filled with envy on seeing the beautiful white plumage of a Swan，and thought it was due to the water in which the Swan constantly bathed and swam.So he left the neighbourhood of the altars，where he got his living by picking up bits of the meat offered in sacrifice，and went and lived among the pools and streams.But though he bathed and washed his feathers many times a day,he didn’t make them any whiter,and at last died of hunger into the bargain.
You may change your habits，but not your nature.
