What's All the Screaming About?

Once a music teacher took her class to their first grand
opera. The lights began to dim, the conductor began
waving his baton, and the soprano started singing.
After a while, one of the students asked the teacher,
"Why does the conductor keep waving his stick at the
woman? What has she done? So the teacher said, "Oh,
don't worry. It's just the way it is. He won't hit her!
Don't worry. And so the student asked, "Then why
is she screaming like that?"

为何尖叫

　　
一位音乐老师带学生去欣赏一流的大型歌剧。当灯光暗下来之
后，歌剧指挥开始挥动他的指挥棒，女高音的歌声随之响起。
过了一会儿，一位学生问老师：「为什么指挥先生一直朝那位
女士挥棒子呢？她做错了什么事吗？」老师回答：「噢！不要
担心，歌剧的演唱方式就是这样，他不会打她的，你不要担心。
」学生又问：「那为什么她要这样大声尖叫呢？」
