In an entrance examination of a conservatory of music, a teacher asked one of the boys, "What is the most important physiological quality of a musician?" "To be deaf," replied the boy. "Nonsense!" said the teacher angrily. "Why, sir! Don't you know that the famous musician Beethoven was deaf?" the boy asked in reply disdainfully. 在一次音乐学院的入学考试中，老师问其中一个男孩："音乐家最重要的生理素质是什么？" "耳聋，"男孩答道。 "胡说！"老师气愤地说。 "怎么了，先生！难道您不知道大名鼎鼎的音乐家贝多芬是个聋子吗？"男孩轻蔑地反问道。
