伊索寓言 The Lion and the Boar

On a summer day, when the great heat induced a general thirst, a Lion and a Boar came at the same moment to a small well to drink. They fiercely disputed which of them should drink first, and were soon engaged in the agonies of a mortal combat. On their stopping on a sudden to take breath for the fiercer renewal of the strife, they saw some Vultures waiting in the distance to feast on the one which should fall first. They at once made up their quarrel, saying: "It is better for us to make friends, than to become the food of Crows or Vultures, as will certainly happen if we are disabled."
