Goose that lays the golden eggs

A man and his wife had a good fortune to possess a goose which lays a golden egg every day. Lucky though they were, they soon began to think that they were not getting rich fast enough, and imaging that the bird must be made of gold inside. They decided to kill it in order to secure the whole store of precious metal at once. When they cut it open, they found it was just like other goose. Thus they neither got rich all at once as they had hoped nor enjoyed any longer the daily addition to their wealth.

下金蛋的鹅

The mice in council

Once upon a time, all the mice met together in council and discussed the best means of securing themselves against the attacks of the cat. After several suggestions have been debated, a mouse of some standing and experience got up and said,
“I think I had hit upon a plan which will ensure our safety in the future, provided you approve and carry it out. It is that we should fasten a bell around the neck of our enemy the cat, which will, by its tinkling, warn us of her approach.”
This proposal was warmly applauded and they had already decided to adopt it. When an old mouse got upon his feet and said,
“I agree with you all that the plan before us is an admirable one. But may I ask who is going to bell the cat.” The mice looked at each other, but nobody spoke.

开会的老鼠们

一群老鼠在鼠洞里举行会议，讨论如何对付凶狠的猫。一只有名望和经验的老鼠站起来提出：“我有个方法，在猫的脖子上挂一个铃。这样，猫一走动铃就响，我们就可以闻铃声而逃避了”，群鼠一致同意这个建议并鼓掌欢呼。大家已经一致决定使用这个办法。就在这时，一只年长的老鼠站起来，说，“这的确是个绝妙的注意，但是问一下，谁去给猫挂铃铛呢？” 老鼠们面面相觑，谁也没有说话。
