THE CROW AND THE PITCHER 乌鸦和水罐（中英）

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.

Necessity is the mother of invention.

一只口渴的乌鸦发现了一个大水罐，虽然里面没有多少水，但毕竟也能解解渴，于是她想尽办法用自己的长喙去接触水面，然而，尽管救命之水就在跟前，可她却无能为力。最后，她想出一条妙计。乌鸦开始用嘴叼着石子投到水罐里，每丢进去一粒石子，水面就会上升一点。终于，水面上升到了乌鸦的嘴边，她高兴地喝到了水，解了口渴。

需求是发明之母。
