伊索寓言:猫和生病的鸡 The Cat and the Birds

The Cat and the Birds
A CAT, hearing that the Birds in a certain aviary were ailing dressed himself up as a physician, and, taking his cane and a bag of instruments becoming his profession, went to call on them.  He knocked at the door and inquired of the inmates how they all did, saying that if they were ill, he would be happy to prescribe for them and cure them.  They replied, "We are all very well, and shall continue so, if you will only be good enough to go away, and leave us as we are."

猫和生病的鸡
猫听说有只鸡生病了，便装扮成医生，带着医疗用品前去看望。他站在鸡窝前面，耐心
地询问鸡哪里不舒服。鸡回答说：“很好，只要你离开这儿，我就不会死。”
这故事说明，坏人即使装出十分善良的样子，聪明的人也会知道他们是口蜜腹剑的人。
