But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (觸發(fā))by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process.Solar energy is only available about half the time we need it — during daylight. For the sun to bee a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun39。 s energy and then releases it as heat to make the ice on the windshield disappear. 7．閱讀理解 故選D。根據(jù)最后一段中的”If Mr Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind. “如果霍華德和其他人如愿以償，那么讓AI軟件開發(fā)變得更容易將會(huì)催生出一批新的不同的果實(shí)。故選A。僅需要中學(xué)數(shù)學(xué)知識(shí)。讓任何想學(xué)習(xí)編寫AI軟件的人都能學(xué)習(xí)這門技術(shù)。根據(jù)五段中的”To make it accessible to anyone who wants to learn …He says school mathematics is sufficient.“可知讓深度學(xué)習(xí)不再神秘是杰里米也就是說fast. ai是一個(gè)提供深度學(xué)習(xí)課程的組織，故選C。根據(jù)第四段中的”Last month fast. ai, a nonprofit education organization based in San Francisco, kicked off the third year of its course in deep learning.“可知。這說明深度學(xué)習(xí)能幫助編寫軟件，故選D。 （1）考查細(xì)節(jié)理解。opening up to all leads to instant global search and online shoppingD.it is quite reliable for anyone to grasp artificial intelligenceB.D.interestingB.easyrequires weeks to apply（3）The underlined words No. Greek.

Some experts worry that this will serve only to create a flood of unreliable AI systems which will be useless at best and dangerous at worst. In the earliest days of the Internet, only a select few nerds, namely puter holies with specific skills, could build applications. Not many people used them. Then the invention of the World Wide Web led to an explosion of web pages, both good and bad. But it was only by opening up to all that the Internet gave birth to online shopping, instant global munications and search. If Mr. Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind.（1）What can we learn about deep learning? A.s course can be pleted in just seven weeks. That is changing. The standard route into these jobs has been a PhD in puter science from one of America39。6．閱讀理解 Learning, Fast and Deep縱觀全文可知，,作者提到無現(xiàn)金支付即電子支付的好處,也提到電子支付引起的擔(dān)憂,對(duì)待電子支付是客觀的,故選C。故選B。大多數(shù)金融公司都渴望放棄它,或者以高昂的費(fèi)用勸阻老式客戶。根據(jù)第四段中的 “But equally important is that suppliers such as banks and tech firms (in developed markets)... 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％?？偟膩碚f,無現(xiàn)金經(jīng)濟(jì)的未來是個(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.s attitude towards digitalized payment is the infrastructure is developing at a high speed in developed marketsD.younger consumers are short of money to live their digital livesB.China is developing faster that those developed countries in digital payment（3）Cash is disappearing largely because that cash is still king across the worldC.. 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
