参考答案
正确答案：D
【D】【定位】根据各选项可分别定位到第7、8、9段。【解析】关于非洲居民迁徙的原因，第8、9段并没有给出确切肯定的说法，维奥拉使用的是wouldhavebeen和wouldn'thavebeen这类猜测的语气，因此选项D中inconclusive（不确定的）与之吻合。【点睛】段落细节题。最后一段指出古非洲居民应该不缺少食物和资源，故A项错误；B项与第8段末句的内容相反；C项不符合第7段末句的内容。【难句分析】●Duringthepastfewyears,aseriesoftoolswerediscoveredattheJebelFayasiteintheU.A.E.,someofwhich-suchashandaxes-hadatwo-sidedappearancepreviouslyseenonlyinearlyAfrica.[分析]someofwhich引导定语从句修饰前面的tools，从句中包含了一个插入语suchas…进行举例说明，previouslyseen...属于分词短语结构充当后置定语，修饰appearance。●DuringthisperiodthesouthernRedSea'slevelsdropped,offeringa“briefwindowoftime”forhumanstoeasilycrossthesea-whichwasthenaslittleas2.5mileswide,accordingtoAdrianParker,aphysicalgeographerfromOxfordBrookesUniversityintheUnitedKingdom.【分析】offering.．，属现在分词短语，充当结果状语，对主句进行补充说明，which引导的定语从句修饰thesea,aphysical…是AdrianParker的同位语。【难词突破】
