Anewstudyfrombrainresearchershelpsexplainhowthehumanbrainevolvedorchangedovertime,topermitpeopletospeakandwrite.

"Thisstudyexaminesthetheoreticalframework(準(zhǔn)則)thatlanguageislearned,storedand'processedintwoancientlearningandmemorysystemsinthebrain."

Ullman,Hamrickandtherestoftheteamlookedatdatafrom16otherstudiesonlanguage.Theyfoundthatpeoplelearnlanguageusingtwomemorysystems:declarativeandprocedural.Memorizingvocabulary,forexample,isadeclarativememoryprocess.Butlearninggrammaris,mostly,aproceduralmemoryprocess.

TheOceanIsRunningOutofBreath【答案】（1）A（2）C（3）A（4）D【解析】【分析】本文是一篇說明文，介紹了海洋氧含量下降是一個與氣候變化有關(guān)的令人擔(dān)憂的趨勢。同時介紹了海洋氧含量下降的原因以及對海洋生物的影響和對其生存的威脅。（1）考查細節(jié)理解。根據(jù)第二段中的"Itisnosurprisetoscientiststhatwarmingoceansarelosingoxygen,butthescaleofthedropcallsforurgentattention.Oxygenlevelsinsometropical(熱帶的)regionshavedroppedbyanastonishing40percentinthelast50years,somerecentstudiesreveal.Levelshavedroppedlesssignificantlyelsewhere,withanaveragelossof2percentglobally."可知，對于科學(xué)家來說，變暖的海洋正在失去氧氣并不奇怪，但這種下降的規(guī)模需要緊急關(guān)注。一些最近的研究表明，在過去的50年里，一些熱帶地區(qū)的氧氣含量下降了驚人的40%。其他地區(qū)的降幅較小，全球平均降幅為2%。所以根據(jù)前兩段，科學(xué)家最擔(dān)心的是變暖的海洋中日益惡化的脫氧現(xiàn)象。故選A。（2）考查細節(jié)理解。根據(jù)第三段中的"aspolarseaicemelts,itformsalayerofwaterabovecolder,moresaltyseawaters.Thisprocesscreatesasortoflidthatcankeepcurrentsfrommixingsurfacewaterdowntodeeperdepths.Andbecausealloxygenentersthesurface,lessmixingmeanslessofitatdepth."可知，當(dāng)極地海冰融化時，它會在更冷、更咸的海水上形成一層水。這個過程會形成一種冰蓋，它可以防止水流將地表水混合到海洋更深的深度。因為所有的氧氣都進入了表面，所以較少的與海洋水的混合意味著更深的海洋含氧量更少。所以表面的極地冰水阻止氧氣下沉是海洋缺氧的原因之一。故選C。（3）考查推理判斷。根據(jù)倒數(shù)第二段中的"Oceananimalslargeandsmall,however,respondtoevenslightchangesinoxygenbyseekingrefugeinhigheroxygenzonesorbyadjustingbehavior,Oschliesandothersinhisfieldhavefound.Theseadjustmentscanexposeanimalstonewpredatorsorforcethemintofood-scarceregions."可知，然而，Oschlies和他所在領(lǐng)域的
