Cash is inefficient. When payments dematerialise, people and shops are less open to theft. It also creates a credit history, helping consumers borrow. Countries are removing cash at varying speeds. In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years. America is perhaps a decade behind. Outside the rich world, cash is still king. But even there its leading role is being challenged. In China digital payments rose from 4% of all payments in 2012 to 34% in 2017. Rich countries are racing to dematerialise payments. They need to do more to prepare for the sideeffects. 【點(diǎn)評(píng)】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，是一篇科教類閱讀，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。s First Digital Teacher Appears in Classroom最符合本文的標(biāo)題。s first kids to be “taught” by a digital teacher”可知，從新學(xué)年開始，新西蘭奧克蘭的小學(xué)生將成為世界上第一批被機(jī)器人老師教的孩子。 （4）考查主旨大意。根據(jù)最后一段中的“However, regardless of how popular it bees, Will is unlikely to replace human educators any time soon.”可知，Ravishankar認(rèn)為它不會(huì)在短期內(nèi)代替人類教育工作者。故選D。 attention, but also allows the program39。 （2）考查細(xì)節(jié)理解。由此可知，特殊之處在于機(jī)器人老師教他們。根據(jù)第一段中的“They became the world39。New Zealand Will Replace Teachers in Classrooms【答案】 （1）A（2）D（3）D（4）B 【解析】【分析】本文是一篇說明文，介紹了一款智能機(jī)器人走進(jìn)小學(xué)課堂，為孩子們講授能源可持續(xù)發(fā)展。The World39。The World39。Disapproving.（4）What might be the best title for the passage?

The digital teacher is assigned to teach Vector39。s first kids to be taught by a digital teacher. Before you start imagining a humanlike robot walking around the classroom, Will is just an avatar that appears on the student39。6．犇犇閱讀理解 ”故選B。根據(jù)最后一段中的“Previous studies have shown some primates (靈長目動(dòng)物), birds, babies and even spiders can add and/or subtract. The new research, published in Science Advances, adds bees to that list.”此前的研究表明，一些靈長類動(dòng)物、鳥類、嬰兒甚至蜘蛛都可以加減法。故選C。但是數(shù)字認(rèn)知，比如精確的數(shù)字和算術(shù)運(yùn)算，需要更復(fù)雜的處理。 （3）考查細(xì)節(jié)理解。t require a massive brain, there might also be new ways for us to include interactions of both longterm rules and working memory in designs to improve rapid AI learning of new problems,”如果數(shù)學(xué)不需要一個(gè)巨大的大腦，那么在設(shè)計(jì)中，我們也可能有新的方法來包括長期規(guī)則和工作記憶的互動(dòng)，從而提高人工智能對(duì)新問題的快速學(xué)習(xí)，可知，Adrian Dyer認(rèn)為，蜜蜂的數(shù)字認(rèn)知對(duì)人工智能的未來發(fā)展可能有影響。 （2）考查推理判斷。研究人員發(fā)現(xiàn)了蜜蜂能做基本的數(shù)學(xué)。根據(jù)第一段中的“Australia showed that bees could perform arithmetic operations like addition and subtraction (減法).”澳大利亞證明蜜蜂可以做加法和減法等算術(shù)運(yùn)算。發(fā)表在《科學(xué)進(jìn)展》(Science Advances)雜志上的這項(xiàng)新研究將蜜蜂也列入了這一名單。The Relationship Between Brain Size and Brain Power【答案】 （1）D（2）B（3）C（4）B 【解析】【分析】本文是一篇說明文，RMIT大學(xué)的研究人員發(fā)現(xiàn)了蜜蜂能做基本的數(shù)學(xué)。New Findings About Bees Having Numerical CogintionC.Some primates, birds and even spiders can add and substract.（4）What can be the best title for the text?

A.has a possible effect on the future development of AIC. numerical cognition ________. A.Bees can perform plex arithmetic operations.D.The relationship between brain size and brain power.B. Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more plex level of processing. “If math doesn39。s Professor Adrian Dyer said numerical (數(shù)字的) operations like addition and subtraction are plex because they require two levels of processing. “You need to be able to hold the rules around adding and subtracting in your longterm memory, while mentally using skillfully a set of given numbers in your shortterm memory,” Dyer said. “On top of this, our bees also used their shortterm memories to solve a
