问题：帮忙通顺的翻译一段话，谢谢Professionalsingers 
 fessional singers and players have great responsibilities, for the composer is utterly dependent on them. A student of music needs as long and as arduous a training to become a performer as a medical student needs to become a doctor. 
回答：试译：
专业演唱者和演奏者责任重大，因为作曲家完全依赖他们。音乐学生要成为表演者，就如医学学生要成为医生，需要漫长而艰苦的训练。
