Today, like most days, her task is to fly as many as three miles from home, stick her long, strawlike tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her coworkers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the b. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only onetwelfth of a tea spoon of me.

The new research, published in Science Advances, adds bees to that list.”此前的研究表明，一些靈長(zhǎng)類動(dòng)物、鳥(niǎo)類、嬰兒甚至蜘蛛都可以加減法。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。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(lái)包括長(zhǎng)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(wèn)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(lái)發(fā)展可能有影響。研究人員發(fā)現(xiàn)了蜜蜂能做基本的數(shù)學(xué)。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。New Findings About Bees Having Numerical CogintionC.Arithmetic operations exist in human and bees.C.has a possible effect on the future development of AIC.Bees can perform plex arithmetic operations.D.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 arithmetic problems, as they learned to recognize plus or minus as abstract concepts.” Solving math problems requires a plex level of involving the mental management of numbers, longterm rules and shortterm working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence, particularly in improving rapid learning.故選D。 （5）考查細(xì)節(jié)理解。）可知，大學(xué)畢業(yè)生對(duì)回家的態(tài)度是積極的，很高興能夠回家，故選B。故選A。 （2）考查詞義猜測(cè)。 （1）考查推理判斷。Not only parents but also children want to be independent.D.It is harder for the children to secure a satisfying job.D.They are doubtful about whether they should return.D.D.causes return.C. Parents on the whole were more uncertain, expressing concern about the likely duration of the arrangement and how to manage it. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities. The young adults taking part in the study were more positive than might have been expected about moving back home—the shame is reduced as so many of their peers are in the same position, and they acknowledged the benefits of their parents39。 The findings contradict research published earlier this year showing that returning adult children trigger a significant decline in their parents39。 【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，是一篇科研類閱讀，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，概括歸納，從而選出正確答案。故選B。 （3）考查推理判斷。 （2）考查推理判斷。The Function of the Brain【答案】 （1）A（2）B（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了為什么老年人會(huì)覺(jué)得時(shí)間過(guò)得較快，主要原因是隨著年齡的增長(zhǎng)，大腦中神經(jīng)元的變化讓老年人的大腦需要更多的時(shí)間來(lái)處理接收到的信息，這樣就會(huì)讓他們覺(jué)得時(shí)間過(guò)得較快。Little babies move their eyes much more often.（4）What is the best title of the text?
