This is likely due largely to the physical changes of our nerves and neurons (神經(jīng)元). New research suggests 39。rapid fire39。 abilities of the young brain allow us to process more information during youth, causing the days to seem longer earlier in life. However, as we get old, researchers say the older brain takes more time to process information. The new finding put forward by a Duke University researcher was published in a paper in the journal European Review this week According to Adrian Bejan, the J. A Jones Professor of Mechanical Engineering 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覺得時間過得較快，主要原因是隨著年齡的增長，大腦中神經(jīng)元的變化讓老年人的大腦需要更多的時間來處理接收到的信息，這樣就會讓他們覺得時間過得較快。 （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，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，年輕時之所以覺得日子似乎更長是因為大腦能夠以“快速射擊”的方式處理更多信息。當(dāng)我們變老的時候，大腦需要更多的時間來處理信息。所以說，相較于老年人，年輕人的大腦花費更少的時間來處理信息。故選B。 （4）考查主旨大意。文章首句點明了文章談?wù)撝行模簽槭裁措S著我們變老，我們會覺得時間過得更快？后面文章主要解釋了原因：老年人因為大腦退化，神經(jīng)元的變化導(dǎo)致他們覺得時間過得較快。C項正好與主旨句呼應(yīng)，故選C。 【點評】本題考點涉及細(xì)節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。2．犇犇閱讀理解 News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world39。s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession. Unlike previous news robots though, Xin does not read news like a cold machine。 she reads it almost like a human being. The muscles on her face stretch and relaxand her reactions changeas she continues reading. That39。s why many news anchors were worried: Will AI replace us in the near future? To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro electric motors behind her face move to make her expressions seem more human. Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person39。s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs Both the technologies used to make Xin39。s performance impressive are mature. The real difficulty lies in the third the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don39。t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.（1）What does the underlined word reluctant in the first paragraph mean? A.Delighted.B.Unwilling.C.Confused.D.Optimistic.（2）What can we infer about previous news robots? A.They read news without expressions.B.They looked like a human beingC.They could interview sports starsD.They could interact with audience.（3）What do we know about the third technology? A.This technology is very perfect so farB.This technology is quite popular nowC.This technology remains at the theoretical stageD.This technology is far from mature.（4）From the last paragraph, we can draw a conclusion that____. A.human news anchors should learn from AT anchors to save their jobsB.Al anchors perform much better than human news anchors at presentC.Al news anchors won39。t replace human news anchors in the near futureD.Xin Xiaomeng s expressions vary so naturally that they are true to life【答案】 （1）B（2）A（3）D（4）C 【解析】【分析】本文是一篇說明文，上周日，新華社新聞主播辛?xí)悦瘸蔀槭澜缟系谝晃慌匀斯ぶ悄苄侣勚鞑?，作者介紹了人工智能背后的技術(shù)，并指出在不久的將來，人工智能新聞主播不會取代人類新聞主播。 （1）考查詞義猜測。根據(jù)第一段中的Xin Xiaomeng began working as the world39。s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on S
