D Once upon a time a pair of crows (乌鸦) were continually upset by a cobra．Every year the snake crawled into their nest to eat the young crows before they learned to fly．They asked their clever friend, the jackal (豺) for help, what to do．
“Do not despair (绝望),” he told them．“ We cannot stop the cobra by force, as we are not strong enough．We will have to use craft (计谋) to destroy that greedy (贪婪的) beast, just do what I tell you and you will be safe．”
The male crow flew obediently (驯从) off to the river where a princess (公主) was bathing, guarded by all her servants．He snatched up the most beautiful necklace left on the shore and flew away just out of reach of the angry servants．Once they were running straight for the cobra’s home, he dashed a head and settled at the window pretending to be lost．
The cobra attacked at once．“Stupid crow,” he thought．“He only just manage to escape, but dropped this valuable necklace in his haste．What will his wife say Now I will be the most magnificent cobra in the world．” However, no sooner had he put it on than the servants appeared and killed him to take the precious thing back．
That year, the crow’s family grew up healthy and safe．
