【正文】 。Ocean acidification is more serious a problem than deoxygenation.C.Not all ocean animals are bothered by the decreasing oxygen levels.D.Some animals reduce their movements in order to absorb more oxygen.（4）Which of the following is the best title of the passage? A.The Oxygen Levels of Marine LifeB.Ocean Warming Affects Food WebC.The Survivability of Ocean AnimalsD.The Ocean Is Running Out of Breath【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It is no surprise to scientists that warming oceans are losing oxygen, but the scale of the drop calls for urgent attention. Oxygen levels in some tropical (熱帶的) regions have dropped by an astonishing 40 percent in the last 50 years, some recent studies reveal. Levels have dropped less significantly elsewhere, with an average loss of 2 percent globally.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 as polar sea ice melts, it forms a layer of water above colder, more salty sea waters. This process creates a sort of lid that can keep currents from mixing surface water down to deeper depths. And because all oxygen enters the surface, less mixing means less of it at depth.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Ocean animals large and small, however, respond to even slight changes in oxygen by seeking refuge in higher oxygen zones or by adjusting behavior, Oschlies and others in his field have found. These adjustments can expose animals to new predators or force them into foodscarce regions. 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。 【點(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。7．閱讀理解 It is the ideal way for traveler to ensure they wake up with the perfect view — a portable Ecocapsule that can be set up anywhere in the world. The eggshaped pod (獨(dú)立艙) ensures travelers can camp in the most extreme corners with all the luxury of a hotel room. Looking like something in a scifi movie, the pod is equipped with solar panels, which guarantee solar energy as its power. In this way the tiny home can let you live fortably wherever you travel. It even has its own shower and toilet, sleeping area for two, and a small kitchen. The 3,306 ib pods can be transported in a seacontainer, meaning the possibilities are endless. Bratislavabased Nice Architects are behind the extraordinary Ecocapsules and said they initially designed them for people who stay in the nature for a long time. However, it quickly became apparent that they could be opened up to the wider public and even used in urban areas to fight against high rent and placed on roofs for studio space or living quarters. The Ecocapsule can serve as a cottage, a popup hotel or even as a charging station for electric cars.The Ecocapsules could even be quickly imported for housing for emergency teams who have been quickly arranged to help with natural disasters. Described by the website as a Swiss Army knife — it packs everything you need, the selfcontained unit can sustain long periods of time without external resources. The 86 sqft pods are able to sleep two people for up to year and for those worried about a cold night39。s sleep, the Ecocapsule has a thick layer which significantly reduce heat loss. The pod is designed to cope with extreme weather conditions due to its innovative (創(chuàng)新的) design and materials used. No wonder the Nice Architects are so confident about its future and the producers are receiving heavy orders.（1）Where does the Ecocapsule get power? A.From a charging station.B.From a portable battery.C.From solar panels.D.From electric cars.（2）Whom may be the Ecocapsule initially designed for? A.Astronauts.B.Office ladies.C.Homeless people.D.Field biologists.（3）The Ecocapsule39。s users don39。t worry about coldness because _______. A.it is a selfcontained unitB.it is equipped with a thick layerC.it has a solar panelD.it has an air conditioner（4）How do the designers view the Ecocapsule39。s future market? A.Optimistic.B.Negative.C.Worried.D.Doubtful.【答案】 （1）C（2）D（3）B（4）A 【解析】【分析】本文是一篇說明文，介紹了一款便攜式產(chǎn)品——Ecocapsule的功能、設(shè)計(jì)原理、大小、技術(shù)構(gòu)造等情況。該產(chǎn)品配有太陽能電池板和可伸縮的風(fēng)力發(fā)電渦輪機(jī)為其提供太陽能和風(fēng)能，可以讓兩個(gè)人同時(shí)入住，有良好的保暖效果。 （1）考查細(xì)節(jié)理解。根據(jù)第二段中的”Looking like something in a scifi movie, the pod is equipped with solar panels, which guarantee solar energy as its power.“看起來就像科幻電影里的某種東西，該產(chǎn)品里面裝有太陽能電池板，保證太陽能作為它的動力?？芍摦a(chǎn)品從太陽能板獲得能量。故選C。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的”Bratislavabased Nice Architects are behind the extraordinary Ecocapsules and said they initially designed them for people who stay in the nature for a long time
