　　DADA 　　29．D细节题．根据Theresearchershopedtofindcluestoexplaintheforceofthemeltingiceanditseffectonsealevelrise，可知研究人员希望找到线索来解释融化冰对海平面的影响，故选D．　　30．A细节题．在文章里Thisisthefarthestsouthwherefishhaveeverbeenseen．Howdidthecreaturesgethere？Whatdotheyfeedon？Andwhateffectwilltheretreatingicehaveonthem？得知，这是最南边发现鱼的地方，通过后面四个问句得知科学家对此发现很惊讶，故选A．　　31．D细节题．根据短语Howdidthecreaturesgethere？Whatdotheyfeedon？Andwhateffectwilltheretreatingicehaveonthem？RossPowellsaystheiceandsedimentcorestakenfromthegroundingzonecanofferclues．推出，这些东西使研究人员得到一点，关于冰层低下生物信息，故选D．　　32．A推理题．在最后一段wehopetobeabletounderstandwhattheicewasdoinginthepast以及ButRossPowellsaystheworkraisesmorequestionsthanitanswers推出，针对此发现，研究人员说还有很多问题是暂时解决不了的，言下之意，科学家将会继续做一些研究．
