昨天我们听了伊索寓言里乌鸦喝水的故事。在这个故事里，乌鸦用了老方法，可是为什么没有喝到水呢？老经验是有用的，但如果情况变了，还照搬老经验，就很可笑了。

Yesterday we listened to Aesop's fable about the crow drinking water. In this story, the crow used the old method, but why wasn't it able to drink the water? Old experience is useful, but if the situation changes, it is ridiculous to copy the old experience.
