《亡羊补牢》故事全文
从前，有个人养了一圈羊。一天早上他准备出去放羊，发现少了一只。原来羊圈破了个窟窿。夜间狼从窟窿里钻进来，把羊叼走了。
邻居劝告他说：“赶快把羊圈修一修，堵上那个窟窿吧！”
他说：“羊已经丢了，还修羊圈干什么呢？”没有接受邻居的劝告。
第二天早上，他准备出去放羊，到羊圈里一看，发现又少了一只羊。原来狼又从窟窿里钻进来，把羊叼走了。
他很后悔，不该不接受邻居的劝告，就赶快堵上那个窟窿，把羊圈修补得结结实实。从此，他的羊再也没有被狼叼走的了。
小故事大道理：羊因为羊圈的空缺被狼叼走了再去修补羊圈，还不算晚。比喻出了问题以后想办法补救，可以防止继续受损失。

The full story of “Mending the Sheep”
Once upon a time, someone raised a flock of sheep. One morning he was about to go out to herd sheep and found one was missing. It turned out that there was a hole in the sheepfold. At night the wolf got in from the hole and took the sheep away.
The neighbor advised him: “Hurry up and repair the sheepfold to plug the hole!”
He said, “The sheep has been lost. What are you doing to repair the sheep pen?” He didn’t accept neighbors’ advice.
The next morning, he was going to go out to herd the sheep. He went to the sheep pen and found that another sheep was missing. It turned out that the wolf came in through the hole again and took the sheep away.
He regretted that he shouldn’t accept the advice of his neighbors, so he quickly plugged the hole and repaired the sheepfold. Since then, his sheep has never been taken away by the wolf.
The story goes: The sheep is taken away by the wolf because of the vacancy in the sheepfold, and it is not too late to repair the sheepfold. Metaphorically, finding a way to remedy the problem can prevent continued losses.
