THE CROW AND THE PITCHER

A thirsty Crow found a Pitcher with some water in it, but so little was there that, try as she might, she could not reach it with her beak, and it seemed as though she would die of thirst within sight of the remedy. At last she hit upon a clever plan. She began dropping pebbles into the Pitcher, and with each pebble the water rose a little higher until at last it reached the brim, and the knowing bird was enabled to quench her thirst.

乌鸦和水罐

一只乌鸦口渴了，找到了一只装着水的水罐，不过水罐中的水很少，她试了半天，嘴巴总是够不到水。唉，尽管水就在眼前，她也可能会被活活渴死的。最后，她灵光一闪，想到了一个主意。她捡起小石子丢到水罐中，每丢进去一颗石子，水面就上升一点，到了最后，乌鸦的嘴巴终于碰到水面了。这只聪明的乌鸦解了渴。
