读短文，判断下列句子正误Wolf does not keep promises
    Here is a bad wolf in the forest. One day he is eating a lamb. Suddenly a bone sticks in his throat. "Oh, a bone is in my throat." He goes to see a doctor, "Please help me." The doctor, Mr. Panda says, "Sorry, I can't help you. The bone is inside." "What can I do?" The wolf is sad. Then he meets a crane (鹤)."Oh, dear Crane. Please help me. A bone is in my throat. I will pay for your help." "OK. Let me have a try," the crane says. She pulls out the bone with her hairpin (发卡)."Now I will go. Remember your words. You should pay me," she says. "Well. Pay you. I remember," the wolf says. With the words, the wolf bites off (咬断) the crane's neck and eats her up.
