<p>问题：【跪求以下这句话的语法分析,Theybelievethedatasupportanideacurrentamongmarinebiologists,thatofthequot;shiftingcaselinequot;.】<p>答案：↓↓↓<p class="nav-title mt10" style="border-top:1px solid #ccc;padding-top: 10px;">程洪波的回答：<div class="content-b">网友采纳 DrMyersandDrWormarguethattheirworkgivesacorrectbaseline,whichfuturemanagementeffortsmusttakeintoaccount.Theybelievethedatasupportanideacurrentamongmarinebiologists,thatofthe"shiftingbaseline".Thenotionisthatpeoplehavefailedtodetectthemassivechangeswhichhavehappenedintheoceanbecausetheyhavebeenlookingbackonlyarelativelyshorttimeintothepast.Thatmattersbecausetheorysuggeststhatthemaximumsustainableyieldthatcanbecroppedfromafisherycomeswhenthebiomassofatargetspeciesisabout50%ofitsoriginallevels.Mostfisheriesarewellbelowthat,whichisabadwaytodobusiness. 答：本题句疑问点在currunt的词性、作用及thatof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： thedatasupportanideacurrentamongmarinebiologists,thatofthe"shiftingcaseline". 从句句法分析： 主语：thedata 谓语：support 宾语：anidea 定语：amongmarinebiologists 插入语：thatofthe"shiftingcaseline". 其中that是替代词=theidea,而that(theidea)与the"shiftingcaseline"是又是同位关系,类似于：thecityofBeijing. 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,currentamong.比currentlyamong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.
