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(gè)與氣候變化有關(guān)的令人擔(dān)憂的趨勢。同時(shí)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(xì)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(xì)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(shí)，它會在更冷、更咸的海水上形成一層水。這個(gè)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?yàn)樗械难鯕舛歼M(jìn)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)域的其他人發(fā)現(xiàn)，無論大小，海洋動物對氧氣的微小變化都有反應(yīng)，它們在較高的含氧區(qū)尋求庇護(hù)，或是調(diào)整行為。這些調(diào)整可能使動物暴露在新的掠食者面前，或迫使它們進(jìn)入食物匱乏的地區(qū)。所以海洋中氧含量減少迫使動物離開自己的棲息地，去氧氣含量較高的地區(qū)尋求庇護(hù)。故判斷出海洋脫氧改變了一些動物的自然領(lǐng)地。故選A。（4）考查主旨大意。通讀全文可知，短文說明了海洋氧含量下降是一個(gè)與氣候變化有關(guān)的令人擔(dān)憂的趨勢，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。所以短文主要是圍繞著海洋氧含量下降而展開的。故短文的最佳標(biāo)題為"海洋快喘不過氣來了"符合題意。故選D?！军c(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇環(huán)保類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。5．閱讀理解
