an ass and a cock were in a straw-yard together when a lion, desperate from hunger, approached the spot. he was about to spring upon the ass, when the cock (to the sound of whose voice the lion, it is said, has a singular aversion) crowed loudly, and the lion fled away as fast as he could. the ass, observing his trepidation at the mere crowing of a cock summoned courage to attack him, and galloped after him for that purpose. he had run no long distance, when the lion, turning about, seized him and tore him to pieces.

牲口棚里住着一头驴子和一只公鸡。【爱好文学】一天，有一头饥肠辘辘的狮子悄悄地靠近这里，想把驴子吃掉。在这危急时刻，公鸡大声啼叫起来，狮子（据说狮子非常害怕公鸡的啼鸣声）顿时吓得趴在地上，随后拔腿就跑。驴子以为狮子是怕了自己才逃跑的，就毫不犹豫地追赶狮子。当他们跑了很远的时候，狮子转过身把自以为是的驴子吃掉了。
