Most financial firms are keen to abandon it, or discourage oldfashioned customers with heavy fees.”可知現(xiàn)金消失的一個(gè)重要原因就是諸如銀行和科技公司（在發(fā)達(dá)市場(chǎng)）和電信公司（在新興市場(chǎng)）之類的供應(yīng)商正在開發(fā)快速,易于使用的支付技術(shù),他們可以從中提取數(shù)據(jù)和小費(fèi)。故選C。根據(jù)第三段中的“In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years.”可知在過(guò)去的十年中,瑞典的人均零售現(xiàn)金交易數(shù)量下降了80％；再根據(jù)“In China digital payments rose from 4% of all payments in 2012 to 34% in 2017.”可知在中國(guó),數(shù)字支付從2012年占所有支付的4％上升到2017年的34％。故選D。根據(jù)第一段中的“Rich countries are racing to dematerialise payments.”可知, 富裕國(guó)家正競(jìng)相將支付非物質(zhì)化；再根據(jù)第三段中的“In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years.”在過(guò)去的十年中,瑞典的人均零售現(xiàn)金交易數(shù)量下降了80％?？偟膩?lái)說(shuō),無(wú)現(xiàn)金經(jīng)濟(jì)的未來(lái)是個(gè)好消息,但是對(duì)于電子支付人們也有一些擔(dān)憂。D.C.B..

A.promote payment without paper money or coins（2）In paragraph 3, several countries are mentioned to show get rid of the sideeffects of cashC.. A. Yet set against these benefits are a couple of worries. Electronic payment systems may risk technical failures, power failure and cyberattacks. In a cashless economy the poor, the elderly and country folk may be left behind. And a digital system could let governments watch over people39。 Cash is dying out because of two forces. One is demand— younger consumers want payment systems that plug easily into their digital lives. But equally important is that suppliers such as banks and tech firms (in developed markets) and teles panies (in emerging ones) are developing fast, easytouse payment technologies from which they can pull data and pocket fees. There is a high cost to running the infrastructure behind the cash economy—ATMs, vans carrying notes, tellers who accept coins. Most financial firms are keen to abandon it, or discourage oldfashioned customers with heavy fees. For the past 3,000 years, when people thought of money they thought of cash. Over the past decade, however, digital payments have taken off— tapping your plastic on a terminal or swiping a smartphone has bee normal. Now this revolution is about to turn cash into an endangered species in some rich economies. That will make the economy more efficient—but it also causes new problems that could hold back the transition(轉(zhuǎn)型).6．閱讀理解 故選D。所以短文主要是圍繞著海洋氧含量下降而展開的。 （4）考查主旨大意。故判斷出海洋脫氧改變了一些動(dòng)物的自然領(lǐng)地。這些調(diào)整可能使動(dòng)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)。 （3）考查推理判斷。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。這個(gè)過(guò)程會(huì)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。 （2）考查細(xì)節(jié)理解。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。一些最近的研究表明，在過(guò)去的50年里，一些熱帶地區(qū)的氧氣含量下降了驚人的40%。 （1）考查細(xì)節(jié)理解。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(shuō)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(shì)。Ocean Warming Affects Food WebC.The Oxygen Levels of Marine LifeNot all ocean animals are bothered by the decreasing oxygen levels.D. natural territories.B.Salty water holds less gas in the increasingly warmer ocean.（3）What can be inferred from the passage? A.Global warming reduces the amount of oxygen in the air.C.The lack of attention to the warming of tropical oceans.（2）Which of the following is a reason for the oxygen loss in the ocean? A.The survival of predators and various marine animals.C. Aside from food web problems, animals face various other physiological challenges as their bodies adjust to lower oxygen levels. Chinese shrimp (蝦) move their tails less vigorously to preserve energy in lower oxygen environments. Some creatures, such as jellyfishes, are more tolerant of low oxygen than others are. But all animals will feel the impact of deoxygenation because they all have evolved their oxygen capacity for a reason, says Oschlies. Any drop in oxygen is going to damage survivability and performance, he says.（1）According to the first two paragraphs, what worries scientists the most? A. A warming ocean loses oxygen for two reasons: First, the warmer a liquid bees, the less gas it can hold. That is why carbonated drinks go flat faster when left in the sun. Second, 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. Escaping predators (食肉動(dòng)物), digestion and other animal activities—including those of humans—require oxygen. But that essential ingredient is no longer so easy for marine life to obtain, several new studies reveal. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和句義猜測(cè)三個(gè)題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯，推理，歸納，從而選出正確答案。根據(jù)字面意思，不難看出其隱藏的意思為：機(jī)器人保姆占據(jù)很大的優(yōu)勢(shì)，他們可以在未來(lái)作更好的工作。 （4）考查句義理解。根據(jù)最后一段中的A huge number of jobs will be produced as autonomous vehicles are released into the environment可知，隨著自動(dòng)化車輛被投放到市場(chǎng)，將產(chǎn)生大量的就業(yè)機(jī)會(huì)。根據(jù)第二段中的which include maintenance, engineering and programming列舉了照看機(jī)器人的
