Organisms Techniques Produced Evolutionary Information Molecular Sequence Rna

意群训练： New techniques for determining the molecular sequence of the RNA of organisms have produced evolutionary information about the degree to which organisms are related ，the time since they diverged from a common ancestor ，and the reconstruction o f ancestral versions of genes .

标志： New techniques {for determin ing the molecular sequence ［of the RNA (of organisms)］} have produced evolutionary information ［about the degree (to which organisms are related）, about the time (since they diverged from a common ancestor）, and about the reconstruction (of ancestral versions of genes)］.

译文： {确定 ［（生物体的）RNA的］分子序列 的}新技术 产生了有关进化的信息， ［这些信息是 关于（生物体的相关的）程度 、关于 （它们从一个共同祖先那里分化出来的）时间 、并且 关于 （对于祖先的基因版本的）重建 的］。

解释： 要是单看主、谓、宾，句子倒是简单：New techniques have produced evolutionary information 。然而问题在于主语和宾语都被长长的定语所修饰。主语的修饰成分是标准的层层修饰，而宾语的修饰成分则是三个并列的介词结构，而且后两个当中省略了介词about。
