试译下这段吧
She(Lise Davidsen) is adamant, however, that she is not ready for the emotional and physical challenge of singing Brunnhilde in Wagner’s “Ring” cycle, the pinnacle of the dramatic soprano repertory and a role that administrators are eager to hire her for. (It lasts 15 hours and is performed over four evenings.) Ms Davidsen compares preparing for such roles to training for a marathon: when developing delicate vocal muscles, she says, it’s important to build stamina.
然而，她（莉丝·戴维森(Lise Davidsen)）坚持认为，她还没有准备好表演瓦格纳《指环》中布伦希尔德(Brunnhilde)的情感和身体挑战，这是戏剧女高音剧目的巅峰之作，也是管理人员急于雇用她的角色。（该剧目持续15个小时，分四个晚上表演。）戴维森女士将准备此类角色比作马拉松训练：她说，锻炼精致的声带肌肉过程中，培养耐力也非常重要。
