In a hospital for mentally disturbed people, when the doctor walked into the room of a patient, he saw him dangling¹ from the ceiling. Being frightened, he called the nurse to come and pull him down for fear that the man might fall to his death. The nurse said; "Doctor, every day this patient thinks that he is a lamp, therefore, he often hangs from the ceiling!" The doctor said;“No,you have to pull him down at once; otherwise, he'll die if he falls down."

一家精神病院里，医生走进一个病人的房间，发现病人正吊在天花板上晃来晃去。医生吓坏了，担心病人摔下来一命呜呼，赶紧叫护士把病人拉下来。护士说：¨医生，这个病人每天都认为自己是一盏灯，所以常常把自己吊在天花板上。“医生说：¨不行，你 还是得马上把他拉下来，免得他摔死。

After a pause,the nurse answered: "But the light will go out after I pull him down!"

护士停顿了一下，说：¨可是，如果我把他拉下来，灯不就熄了吗？
