Long long ago，there was an old lion who was ill in his den（兽穴）.All the animals came to visit him，but none of them could do anything for him and every day he grew weaker and weaker.
"Have you noticed，my lord lion，"said the wolf one day，"that the fox has not been here to see you？You can tell he doesn’t care at all for you.However he flatters（阿谀，奉承）you when you are well and strong."
The fox happened to pass by at that moment and overheard what the wolf said.He came back at once and said，"I’m afraid，sir，that the wolf does not understand things well.I care more about you than anyone else.While he has been chattering（喋喋不休）at your side，I’ve been rushing many places trying to find a cure（疗法）for you，I’m quite tired out.
"Have you found anything？"asked the lion eagerly.
"Yes，indeed I found a good old doctor.He says you must wrap（裏）yourself in a newly killed wolf skin.That’s the only thing that will make you better."，Before the wolf knew what was happening，the lion had sprung up and killed him for his warm skin.
Aha！"laughed the fox."You won’t stir up（搅起）trouble again，Mr Wolf."
Troublemakers make trouble for themselves.
