，符合语境。故选G。12．根据上文“Maybeyoualreadylovetowalk,butyou’regettingtiredofgoingyoursameoldroutedayafterday.Ormaybeyou’renewtowalkingandaren’tsurehowtogetstarted.(也许你已经喜欢散步了，但是你厌倦了日复一日走同样的路线。或者也许你是步行的新手，不知道如何开始)”可知，F选项“Eitherway,it’stimetohugtheideaofwalkingwithapurpose.(不管怎样，是时候拥抱带着目的散步的想法了)”能够承接上文，其中的“Eitherway”和前面的“Maybe...Ormaybe”一致，且引出了下文的“带着目的散步的做法”，符合语境。故选F。13．根据上文“Doyouwanttomeetotherpeople?(你想认识其他人吗？)”及下文“Getoutintothewildernessorexploreacity?(去野外还是探索城市？)”可知，这都是说的想从散步中得到的好处，空格处应该也是一个问题。由此可知，A选项“Seenewplaces?(看看新地方？)”能够承上启下，也是一个从散步中可以获得的好处，且是一个问题，符合语境。故选A。14．根据上文“Ifmakingfriendsandsocializingisyourgoal,callupyourfriendsandschedulewalkswiththem.(如果交朋友和社交是你的目标，打电话给你的朋友，安排和他们一起散步)”及下文“Goonlineandlookupyourlocalmallorshoppingcenter.(上网查查当地的商场或购物中心)”可知，C选项“Askyourfriendswheretheyliketowalkandgo.(问问你的朋友他们喜欢去哪里散步)”能够承上启下，其中的“Askyourfriends”和前面的“callupyourfriends”相一致，“wheretheyliketowalk”和后文的“localmallorshoppingcenter”相一致，且说明了要问朋友想去散步的地方，符合语境。故选C。15．根据下文“Nearlyanycityyoucanthinkofoffersawalkingtourwithmapsprovidedbythetouristbureau.(你能想到的几乎所有城市都有由旅游局提供的步行旅游地图)”可知，E选项“Manycitiesofferdetailedandwell-plannedwalkingtours.(许多城市都提供详细而精心规划的徒步旅行)”能够引起下文，其中的“Manycities”和后文的“Nearlyanycity”相一致，“walkingtours”和后文的“walkingtour”一致，说明许多城市都提供徒步旅行，符合语境。故选E。16．C17．D18．B19．G20．F【导语】本文是一篇说明文。文章主要介绍了如何找到一个一起锻炼的伙伴。16．根据前文“FitnessMagazinerecentlyrananarticletitled“FiveReasonstoThankYourWorkoutPartner.”Onereasonwas:“You’llactuallyshowupifyouknowsomeoneiswaitingforyouatthegym,”(《健身杂志》最近刊登了一篇题为《感谢健身伙伴的五个理由》的文章。一个理由是：“如果你知道有人在健身房等你，你就会去锻炼。”)”以及后文“Withaworkoutpartner,youwillincreaseyourtrainingeffortasthereisasubtle(微妙)competition.(有一个锻炼伙伴，你将会努力训练，因为你们之间有一个微妙的竞争)”可知，空处陈述另一个和别人一起锻炼的理由，故选项应与后文是顺承关系，选项C中的“trainwithsomeoneelse”与后文的“Withaworkoutpartner”相对应，选项C“You’llworkharderifyoutrainwithsomeoneelse.(如果你和别人一起训练，你会更努力)”符合语意。故选C项。17．根据前文“Firstofall,decidewhatyouwantfromthatperson.(首先，决定你想从那个人身上得到什么)”和后文“Ordoyoujustwanttobephysicallyfit,abletomovewithstrengthandflexibility?(或者你只是想要身体健康，能够移动的力量和灵活性?)”可知，这里是一个问句，反问自己结伴锻炼的目的，故空处与后文是选择关系，你要知道你锻炼是为了什么。所以选项D“Doyouwanttobeabetterathleteinyourfavoritesport?(你想在你最喜欢的运动项目上成为更好的运动员吗?)”与后文在语意上构成选择关系。故选D项。18．根据前文“Youmightthinkaboutpostingwhatyouarelookingforonsocialmedia,butitprobablywon'tresultinausefulresponse.(你可能会考虑在社交媒体上发布你想要的东西，但可能不会得到有用的回应)”和后文“Ifyouplanonworkingoutinagym,thatpersonmustbelongtothesamegym.(如果你打算在健身房锻炼，那个人一定是同一个健身房的)”可知，寻找的锻炼伙伴要具有便利性的特点。选项B中的“livecloseby”与后文的“belongtothesamegym”相对应，选项B“Aworkoutpartnerusuallyneedstolivecloseby.(锻炼伙伴通常需要住在附近)”与下文是顺承关系。故选B项。19．根据前文“Mypartnerpostedherrequestonthenoticeboardofalocalpark.Hernoticeincludedwhatkindoftrainingshewantedtodo,howmanydaysaweekandhowmanyhoursshewantedtospendoneachsession,andherage.Italsolistedherfavoritesportsandactivities,andprovidedherphonenumber.(我的搭档把她的要求贴在了当地公园的布告栏上。她的注意事项包括她想要做什么样的锻炼，每周多少天，每次培训要花多少小时，以及她的年龄。它还列出了她最喜欢的运动和活动，并提供了她的电话号码)”可知，本段作者以自己的锻炼伙伴为例，说明寻找锻炼伙伴布告所要包括的信息。所以选项G“Anynoticeforatrainingpartnershouldincludesuchinformation.(任何锻炼伙伴的布告都应包括这些信息)”是对上文内容的总结，符合语意。故选G项。20．根据前文“Youandyourpartnerwillprobablyhavedifferentskills.(你和你的伴侣可能有不同的技能)”和后文“Overtime,bothofyouwillbenefit—yourpartnerwillbeabletoliftmoreweightsandyouwillbecomemorephysicallyfit.Thecore(核心)ofyourrelationshipisthatyouwillalwaysbetheretohelpeachother.(久而久之，你们双方都会受益—你的伴侣会举起更多的重量，你也会变得更健康。你们关系的核心是你们永远在一起互相帮助)”可知，要学会求同存异，一起合作，共同提高。选项F中的“differences”对应前文的“differentskills”，选项中的“workwitheachother”对应后文的“betheretohelpeachother”，故选项F“Justacceptyourdifferencesandlearntoworkwitheachother.(接受你们的不同，学会彼此合作)”起到承上启下的作用，符合语意。故选F项。【点睛】21．B22．F23．A24．D25．E【导语】这是一篇说明文。文章主要说明了如果我们不经常运动，我们会变得更胖，我们会有心脏问题，我们可能会得糖尿病，但新的研究表明，它也会损害我们的心理健康，导致抑郁。但好消息是运动可以解决这一问题。21．根据上文“SincethestartoftheCOVID-19pandemic,manypeoplehavebeenstuckindoors.Onlineclassesandworkingfromhomemeanalotofsittingaroundonyourbutt.Wealreadyknowthatifwedon’tmovemuch,wegetfatter,wegetheartproblemsandwemaygetdiabetes.(自2019冠状病毒疾病大流行以来，许多人一直被困在室内。在线课程和在家工作意味着你要坐在那里无所事事。我们已经知道，如果我们不经常运动，我们会变得更胖，我们会有心脏问题，我们可能会得糖尿病)”可知，本句为本段最后一句，应承接上文继续说明不运动给身体带来的危害。故B选项“但新的研究表明，它也会损害我们的心理健康”符合语境，故选B。22．根据后文“Itfoundthateachextrahourofsittingtimeatages8,10and12ledtohigherdepressionscoresbyage18.Eighteen-year-oldswhosatmostoftenhaddepressionscores28percenthigherthanthosewhoweremoreactive.(研究发现，在8岁、10岁和12岁时，每多坐一小时，18岁时的抑郁得分就会更高。经常坐着的18岁青少年的抑郁得分比那些经常运动的青少年高出28%)”可知，后文提到了关于青少年的研究发现，可见本段是在说明针对儿童的研究发现，F选项中Anotherstudy对应后文中it。故F选项“另一项针对儿童的研究”符合语境，故选F。23．根据后文“ButaccordingtoMatsHallgrenfromtheKarolinskaInstituteinSweden,“sittingfortoolongcanslowbloodflowinthebody,includingbloodflowtothebrain.”Itmightalsoaffectthegrowthofneuronsinthebrain.Andcouchpotatoesmightdootherunhealthythingswhilesitting,suchassnackingonjunkfood.Allthesemayleadtodepression.(但瑞典卡罗林斯卡学院的MatsHallgren表示：“久坐会减缓体内血液流动，包括大脑的血液流动。”它还可能影响大脑神经元的生长。坐在沙发上看电视的人可能会做其他不健康的事情，比如吃垃圾食品。所有这些都可能导致抑郁)”可知，后文主要说明了久坐会导致抑郁症的原因，且提到了各种导致抑郁的可能因素，可见久坐与抑郁症之间的联系还不能确定。故A选项“科学家们还不确定久坐与抑郁症之间的联系”符合语境，故选A。24．根据上文“Thegoodnews?(好消息是什么呢？)”以及后文“AaronKandolafromUniversityCollegeLondon,UK,said“alltypes”ofmovementmighthelp,evenlightactivity.“Itisgreattoexerciseandplaysports,”saidKandola.“Butanythingyoucandotoavoidsittingfortoolongwillhelpwithmood,stressandthinkingclearly.”(英国伦敦大学学院的亚伦·坎多拉说，“所有类型”的运动都可能有帮助，即使是轻微的活动。坎多拉说：“这里非常适合锻炼和运动。但任何避免久坐的方法都有助于缓解情绪、缓解压力、清晰思考。”)”可知，后文提到了解决方法，可见好消息就是这种情况可以得到克服。故D选项“很容易克服”符合语境，故选D。25．根据上文“AaronKandolafromUniversityCollegeLondon,UK,said“alltypes”ofmovementmighthelp,evenlightactivity.“Itisgreattoexerciseandplaysports,”saidKandola.“Butanythingyoucandotoavoidsittingfortoolongwillhelpwithmood,stressandthinkingclearly.”(英国伦敦大学学院的亚伦·坎多拉说，“所有类型”的运动都可能有帮助，即使是轻微的活动。坎多拉说：“这里非常适合锻炼和运动。但任何避免久坐的方法都有助于缓解情绪、缓解压力、清晰思考。”)”可知，本句为本段最后一句，且上文提到了任何避免久坐的方法都有帮助，可见关键在于多动。故E选项“关键信息就是多动”符合语境，故选E。26．G27．F28．A29．B30．D【导语】这是一篇说明文。介绍了一些防止人们在体育运动中受伤的策略。26．上文“Playingsportsisalotoffun.Gettinghurtisnot.(运动是有趣的，但是受伤是不好的)”提出了运动中受伤的问题，选项G“采取以下策略来
