你好！请高手分析一下这个句子结构，new concept English 3册35课，Reward or punishment are meted out quite independent of human interference .请问一下quite independent of human interference在此作什么句子成份，若作定语修饰reward or punishment能用being independent of human interference(课文解释be independent of是;不受...的意思。但在此并没有be动词。是省落了吗?)吗，作状语应该解释不通吧？请您分析一下这个句子结构。谢谢！
