这个同位语是做什么成分的
请英语高手们给我分析翻译一下这句话的成分和意思?我不清楚has been后面的that是具体做什么成分,它修饰的那部分?
A basic tenet that has guided the manegement of soil organic matter for decades has been that equilibrium levels of carbon and nitrogen are controlled by their net input and that qualitative differences in these inputs are relatively unimportant. laroo1982 1年前他留下的回答 已收到1个回答

首先应该找到句子的主谓宾,主语：A basic tenet ,谓语：has been,宾语是两个从句,用that引导的,that has guided the manegement of soil organic matter for decades 做A basic tenet 的定语从句,that equilibrium levels of carbon and nitrogen are controlled by their net input 和 that qualitative differences in these inputs are relatively unimportant.为两个句子,做整个句子的宾语,一般宾语只能是名词,这里是句子,所以要用that引导下
