【文章內(nèi)容簡介】 anical 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，考生需要準確捕捉細節(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。5．犇犇閱讀理解 Environmental experts warn that our planet is drowning in plastic. The world39。s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic. Now, that may be changing. A new environmentallyfriendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland. This shopping model, called Loop, aims to replace throwaway containers with reusable ones. Loop is the idea of Terra Cycle, an Americanbased recycling pany. Its chief, Tom Szaky told the Associated Press (AP) that removing plastics from the ocean is not enough. He said the point is to get away from singleuse packages. Szaky said that Loop is the future of shopping. But it es from an idea of the past. He pared it to the milkman model of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste. Jennifer Morgan from the environmental nonprofit organization Greenpeace also joined in the discussion about Loop at Davos. She said that Greenpeace weles the aim of the Loop Alliance to move away from throwaway culture and disposability. But Morgan questioned whether panies worldwide are ready to change their business models. Loop is set to launch later this year in three eastern . states, and also in Paris, France and some of the surrounding area. Then Loop plans to expand to the . West Coast, Toronto, Canada and Britain by the end of this year or 2020.（1）What does the author intend to do in Paragraph 2? A.Provide background information.B.Advocate zerowaste lifestyle.C.Explain the reason for trash.D.Introduce a new topic.（2）Where does the idea Loop e from? A.The World Economic Forum.B.Demand of some panies.C.Zerowaste model.D.The milkman model.（3）Which countries is Loop expected to expand to by 2020? A.United States and Switzerland.B.Switzerland and Britain.C.Canada and Britain.D.France and Canada.（4）What is the text mainly about? A.A new shopping model.B.The development of future city.C.The world39。s environmental issue.D.The concerns of future shopping.【答案】 （1）A（2）C（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹美國一家公司推出一種新的零浪費購物模式。 （1）考查推理判斷。根據(jù)第二段“The world39。s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic.”可知，世界上的城市每年產(chǎn)生大量的垃圾，并且其中最大的垃圾量是塑料，結(jié)合下文可知，作者寫本段目的是為下文提出新的購物模式提供背景信息。故選A。 （2）考查細節(jié)理解。根據(jù)第四段中的“Szaky said that Loop is the future of shopping. But it es from an idea of the past.”和第五段“He pared it to the milkman model of the 1950s in the United States.
