【文章內(nèi)容簡(jiǎn)介】 at Duke, the physical changes of our nerves and neurons play, a major role in our perception (知覺) of time as we get old. Over the years these structures bee more plex and eventually begin to degrade. Little babies, for example, move their eyes much more often than adults because they39。re processing images at a faster rate, Beian says, For older people, this means fewer images are being processed in the same amount of time, causing experiences to seem as though they39。re happening more quickly.（1）What causes time to fly faster as we get old? A.Changes of our nerves and neurons.B.Information in our brain.C.The electrical signals.D.Rapid fire abilities.（2）What is unavoidable in the process of getting old? A.Longer days.B.Aging brains.C.More images.D.Less experience.（3）Why do the days seem longer earlier in life? A.Young people are more energetic in their life.B.The younger brain takes less time to process information.C.Old people have fewer things to do than young people.D.Little babies move their eyes much more often.（4）What is the best title of the text? A.Nerves and NeuronsB.Time Flies FastC.The Older, the FasterD.The Function of the Brain【答案】 （1）A（2）B（3）B（4）C 【解析】【分析】本文是一篇說明文，介紹了為什么老年人會(huì)覺得時(shí)間過得較快，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)間來處理接收到的信息，這樣就會(huì)讓他們覺得時(shí)間過得較快。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的 This is likely due largely to the physical changes of our nerves and neurons (神經(jīng)元).可知，老年人覺得時(shí)間過得過快的原因是神經(jīng)和神經(jīng)元的變化。故選A。 （2）考查推理判斷。根據(jù)第一段中的You39。ve got your aging brain to blame.和第二段中的Over the years, these structures bee more plex and eventually begin to degrade.可知，隨著年齡的增長(zhǎng)，不可避免的就是大腦結(jié)構(gòu)的老化。故選B。 （3）考查推理判斷。根據(jù)第一段中的最后兩句可知，年輕時(shí)之所以覺得日子似乎更長(zhǎng)是因?yàn)榇竽X能夠以“快速射擊”的方式處理更多信息。當(dāng)我們變老的時(shí)候，大腦需要更多的時(shí)間來處理信息。所以說，相較于老年人，年輕人的大腦花費(fèi)更少的時(shí)間來處理信息。故選B。 （4）考查主旨大意。文章首句點(diǎn)明了文章談?wù)撝行模簽槭裁措S著我們變老，我們會(huì)覺得時(shí)間過得更快？后面文章主要解釋了原因：老年人因?yàn)榇竽X退化，神經(jīng)元的變化導(dǎo)致他們覺得時(shí)間過得較快。C項(xiàng)正好與主旨句呼應(yīng)，故選C。 【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。5．犇犇閱讀理解 Researchers have found bees can do basic mathematics, in a discovery that deepens our understanding of the relationship between brain size and brain power. Recently, A study conducted by researchers from RMIT University in Melbourne, Australia showed that bees could perform arithmetic operations like addition and subtraction (減法). 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. RMIT39。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.” The findings suggest that advanced numerical cognition (認(rèn)知) may be found much more widely in nature among nonhuman animals than previously suspected. “If math doesn39。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,” said Dyer. 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. Previous studies have shown some primates (靈長(zhǎng)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.（1）What have the researchers from RMIT University discovered?
