原文：
冬日的一天，农夫发现一条冻僵了的蛇。他很可怜它，就把它放在怀里。当他身上的热气把蛇温暖以后，蛇很快苏醒了,露出了残忍的本性，给了农夫致命的伤害。农夫临死之前说：“我竟然去可怜毒蛇，就应该受到这种报应啊。”
英文译文：
The Farmer and the Snake
ONE winter a farmer found a snake stiff and frozen with cold. He had compassion on it, and taking it up, placed it in his bosom. The snake was quickly revived by the warmth, and resuming its natural instincts, bit its benefactor, inflicting on him a mortal wound. "Oh," cried the farmer with his last breath, "I am rightly served for pitying a scoundrel,
" The greatest kindness will not bind the ungrateful.
中心
这个故事是说，做人一定要分清善恶，只能把援助之手伸向善良的人。对那些恶人即使仁至义尽，他们的本性也是不会改变。
编辑本段寓意
鞭挞了那些恩将仇报的恶人和帮助恶人的伪善的人。告诫我们要学会辨认是非，不要与坏人打交道，因为狐狸也会哭泣、蛇也有落难的时候，所以这则寓言告诫我们要明辨是非。
