Question

跪求以下这句话的语法分析，要详细的。

They believe the data support an idea current among marine biologists, that of the"shifting caseline".

Answer 1

Dr Myers and Dr Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the "shifting baseline". The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
答：本题句疑问点在currunt的词性、作用及that of 上。搜索发现没有打错，没有漏打。
句法分析：
主语：They
谓语：believe
宾语：省略了that的一个从句：
the data support an idea current among marine biologists, that of the"shifting caseline".
从句句法分析：
主语：the data
谓语：support
宾语：an idea
定语： among marine biologists
插入语：that of the"shifting caseline".
其中that是替代词=the idea, 而that (the idea)与the "shifting caseline"是又是同位关系，类似于：the city of Beijing.
其中current 疑为currently 之笔误，是副词修饰后面的介词短语among...的，目前海洋生物学家所持有的（观点）
但网上搜索，current among。。。比currently among用得更普遍！看来current象straight一样，也可以当副词用，修饰介词短语了。
