DOver the last decades,we have witnessed an ever-increasing use of electronic devices,leading in turn toelectronic waste (e-waste)becoming the world's fastest growing waste stream.In 2019,a total of 53.6 Mt of e-waste was generated globally,only 17 percent of which is documented as having been managed in anenvironmentally sound manner,which has been pushing researchers to address the e-waste problem.Now researchers at the Cellulose Wood Materials Laboratory have crafted a water-activated disposablebattery made of paper and other environmentally friendly materials.The new paper battery has the same key components as traditional standard batteries.Like a traditionalchemical battery,it has a positively charged side called a cathode,a negatively charged side called an anode and aconductive material called an electrolyte between the two.Instead,in the new battery,the anode and cathode areinks printed onto the front and back of a piece of paper.That paper is filled with salt.It will dissolve when you addjust a couple of drops of water to the paper.The resulting saltwater solution acts as the electrolyte,which allowselectrons to flow.About 20 seconds later,the battery will produce a stable 1.2 volts of electricity until the paperdries out.(For comparison,a standard AA battery provides 1.5 volts.)The researchers demonstrated that their battery could present a sustainable alternative to the more harmfulbatteries that are common in low-power devices,such as an alarm clock.Nystrom,head of the research,evenpictures a bright future where these batteries are applied to diagnostic tests in hospitals and environmental sensors,ideally with other sustainable components such as screens and packaging."That future may not be so far off."Nystrom said hopefully.It is hard to predict a time line for producing such items on a large scale,but Nystrom says he is in contactwith potential industry partners and believes these batteries could make their way into products within the next twoto five years.12.What can we learn from paragraph 1?A.Electronic devices are overly used.B.Electronic devices are the main source of waste.C.Electronic waste has become a global problem.D.Electronic waste is mostly managed in a sound way.13.What does the underlined word "It"in paragraph 3 mean?A.The salt.B.The paper.C.The battery.D.The ink.14.What do we know about the new paper battery?A.It has come into the market.B.It can power common electrical equipment.C.It has the same anode and cathode as the traditional battery.D.It stops producing electricity when the saltwater solution dries out.15.How does Nystrom feel about the future of the paper battery?when you add just a couple of drops of water to the paper'”可知，纸上注入了盐，当你往纸上滴几滴水时，盐就会溶解。故t指的是“盐”。故选A。【14题详解】细节理解题。根据第三段中“The resulting saltwater solution acts as the electrolyte,which allows electrons toflow.About 20 seconds later,the battery will produce a stable 1.2 volts of electricity until the paper dries out.(产生的盐水溶液充当电解质，使电子流动。大约20秒后，电池会产生稳定的1.2伏特电流，直到纸张干涸)”可知，当盐水溶液干涸时，它就停止发电。故选D。【15题详解】推理判断题。根据最后一段“It is hard to predict a time line for producing such items on a large scale,butNystrom says he is in contact with potential industry partners and believes these batteries could make their way intoproducts within the next two to five years.(很难预测大规模生产这类产品的时间线，但Nystrom表示，他正在与潜在的行业合作伙伴接触，并相信这些电池可以在未来两到五年内投入生产)”可推知，Nystro心m对于新型纸电池的未来持乐观态度。故选B。A.Indifferent.B.Positive.C.Negative.D.Doubtful.【答案】12.C13.A14.D15.B【解析】【导语】本文是一篇说明文。在过去的几十年中，电子垃圾已经成为全球增长速度最快的废物。为了解决当前电子垃圾泛滥问题，科学家提出了一种可以用水激活的纸电池。【12题详解】细节理解题。根据第一段“Over the last decades,.we have witnessed an ever-.increasing use of electronicdevices,leading in turn to electronic waste (e-waste)becoming the world's fastest growing waste stream.In 2019,atotal of 53.6 Mt of e-waste was generated globally,only 17 percent of which is documented as having beenmanaged in an environmentally sound manner,which has been pushing researchers to address the e-wasteproblem.(在过去的几十年里，我们目睹了越来越多的电子设备的使用，导致电子垃圾成为世界上增长最快的废物流。2019年，全球共产生了5360万吨电子垃圾，其中只有17%被记录为以无害环境的方式进行管理，这一直在推动研究人员解决电子垃圾问题)”可知，电子垃圾已经成为全球性问题。故选C。【13题详解】词句猜测题。根据画线词上文“That paper is filled with salt(那张纸里装满了盐)”以及后文“will dissolvewhen you add just a couple of drops of water to the paper'”可知，纸上注入了盐，当你往纸上滴几滴水时，盐就会溶解。故t指的是“盐”。故选A。【14题详解】细节理解题。根据第三段中“The resulting saltwater solution acts as the electrolyte,which allows electrons toflow.About 20 seconds later,the battery will produce a stable 1.2 volts of electricity until the paper dries out.(产生的盐水溶液充当电解质，使电子流动。大约20秒后，电池会产生稳定的1.2伏特电流，直到纸张干涸)”可知，当盐水溶液干涸时，它就停止发电。故选D。【15题详解】推理判断题。根据最后一段“It is hard to predict a time line for producing such items on a large scale,butNystrom says he is in contact with potential industry partners and believes these batteries could make their way intoproducts within the next two to five years.(很难预测大规模生产这类产品的时间线，但Nystrom表示，他正在与潜在的行业合作伙伴接触，并相信这些电池可以在未来两到五年内投入生产)”可推知，Nystro心m对于新型纸电池的未来持乐观态度。故选B。
