人类在咒骂同类时常用的最为刻薄的一句话就是"禽兽不如"。表面看，我们对飞禽走兽时多么鄙视，实际上却说明我们对它们是那么的不了解，解释我们一直不耻与之为伍，但人类、兽类、鸟类以及地球上的所有生物终归都是地球村的成员。有时候，飞禽走兽的生活方式和行为规范很值得人们学习和借鉴。(The worst curse that one human can swear at another is "worse than animals ". Outwardly, this shows how much we despise the animals. However, this actually shows how much we do not understand them. We consider it as a shame to associate with animals, but after all, humans, mammals, birds and all lives on the earth are inhabitants of this planet. Sometimes, the lifestyles and behavioral norms of animals are worth learning.)
