翻译的最好就是要看整个语境,并且意译才最适合mettle本来就有 勇气 气质 耐力的意思eg:His first important chance to show his mettle came when he opened the new session of the legislature.　这里就要翻译成显...十分感谢！！！是讲企业家在事业失败后如何重新获得成功的，其中有一个小标题是“prove your mettle"里面的有句话是”when you show that you can still perform at a credible or superior level, others will begin to think of you as having the mettle to triumph over your career calamity.在这个语境中该如何翻译呢？这里我觉得翻译成为‘证明你的魄力’比较适当因为句子里说 要展现你是一个可靠的人，或上级；有勇气和谋略能够应付职场上的不幸事件
