【正文】 。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。其他地區(qū)的降幅較小，全球平均降幅為2%。故選A。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，它會在更冷、更咸的海水上形成一層水。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。故選C。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。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)。故選A。通讀全文可知，短文說明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，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。故短文的最佳標(biāo)題為海洋快喘不過氣來了符合題意。 【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。 In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards39。 The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks—provided the task is in one field with a lot of data—it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the plex, strategic jobs—executives, diplomats, economists — go well beyond the AI limitation of singlefield and Big Data. Then there are the asyetunknown jobs that will be created by AI.t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require passion, trust and sympathy—which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.To introduce the topic.B.s feat.C.To suggest humans go beyond AI in memory.（2）Which of the following best explains outperform underlined in paragraph 2?

The key then must be retraining the workforce so people can do them.” 可知作者認(rèn)為在AI時代仍然會有工作,關(guān)鍵必須是對勞動力進(jìn)行再培訓(xùn),這樣人們才能從事這些工作。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科技類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。 Over the past five years researchers in artificial intelligence have bee the rock stars of the technology world. A branch of AI known as deep learning, which uses neural(神經(jīng)的) networks to scan through large volumes of data looking for patterns, has proven so useful that skilled practitioners can mand high sixfigure salaries to build software for Amazon, Apple, Facebook and Google.s top universities. Earning one takes years and requires a personality suited to academia, which is rare among more normal folk. Last month , a nonprofit education organization based in San Francisco, kicked off the third year of its course in deep learning. Since its foundation it has attracted more than 100, 000 students around the globe from India to Nigeria. The course and others like it, e with a simple idea: there is no need to spend years obtaining a PhD in order to practise deep learning. Creating software that learns can be taught as a craft, not as a high intellectual pursuit to be undertaken only in an ivory tower. Fast. ai39。 To make it accessible to anyone who wants to learn how to build AI software is the aim of Jeremy Howard, who founded with Rachel Thomas, a mathematician. He says school mathematics is sufficient. No. Greek.
