B.AppalachianTrail.C.TigerLeapingGorge. D.TourduMontBlanc.【答案】21.B22.D23.C【语篇解读】本文是一篇应用文。文章主要介绍了全球四条适合不同技能水平徒步者的著名步道。【21题详析】细节理解题。根据AppalachianTrail(USA)部分中“Springandautumnareidealseasonstoavoidextremeweather.(春季和秋季是避开极端天气的理想季节)”可知，徒步者计划完成阿巴拉契亚步道时要考虑准备应对极端温度变化。故选B。【22题详析】细节理解题。根据IncaTrail(Peru)部分中“Suitableforexperiencedhikersduetohighaltitudes(upto4,200m),itcombineshistoryandbreathtakingviews.(由于海拔较高（高达4200米），这条路线适合有经验的徒步旅行者，它将历史和令人惊叹的景色结合在一起。)”以及TourduMontBlanc(Europe)部分中“CirclingWesternEurope’shighestpeak,this170kmtrailcrossesFrance,Italy,andSwitzerlandin10-12days.Thoughphysicallydemandingduetoaltitudechanges,itsclearsignageandmountainhutsmakeitaccessibletointermediatehikers.(这条170公里的路线环绕着西欧最高峰，在10到12天内穿越法国、意大利和瑞士。虽然由于海拔变化对体力要求很高，但它清晰的路标和山间小屋使中级徒步旅行者也可以到达。)”可知，印加古道和环勃朗峰徒步路线的共同之处在于它们都有高海拔带来的挑战。故选D。【23题详析】细节理解题。根据TigerLeapingGorge(China)部分中“Whilethepathhassteepsectionsrequiringenoughfitness,itremainspopularwithbothChineseandinternationalhikers.Thehighlight‘28Bends’sectionrewardshikerswithbreathtakingviewsbutrequires3hoursofcontinuousascent.LocalguesthousesalongtherouteprovideculturalimmersionintoNaximinoritytraditions.(虽然这条路线有一些陡峭的路段，需要徒步者具备足够的体能，但它仍然深受中国和外国徒步旅行者的喜爱。其中最精彩的“二十八道拐”路段会让徒步者欣赏到令人叹为观止的美景，但需要持续攀登三个小时。沿途的当地民宿能让人们深入体验纳西族的传统习俗。)”可知，TigerLeapingGorge这条步道最适合想要将体力挑战与文化体验相结合的徒步者。故选C。BDr.SarahtightlyheldthestrapofhermedicalbagasthejeepbouncedalongthecrackedroadinnorthernZambia.Thedry-seasonwindcarriedreddustthatcoveredeverything—hernotes,thetemporaryclinic’swindows,eventhebandages.For18months,she’dservedherewithDoctorsWithoutBorders,yetthesightofchildrenliningupbarefootatdawnstillpiercedherheart.Lastmonth,tribalconflictsbrokeoutneartheclinic.Sarahwassewingupafarmer’sknifewoundwhenshoutingeruptedoutside.Shepushedtwonursesintothestorageroomjustasastonesmashedthroughthewindow.Glasspiecescutherforearm,butshekeptpressureonthefarmer’sbleedingarteryuntilthechaosbecamecalm.Thatevening,shetextedherparents:“Don’tworry—scratchesfade.Hopedoesn’t.”Thecruelestmomentscamequietly.Twoweeksago,ateenagemotherhadwalked12milescarryingafeverishbaby.Sarahdiagnosedcerebralmalaria,butthemedicineshadrunout.Sheheldthetinybodyasiflifeslippedaway,tearsmixingwiththemother’ssilentsorrow.Yet,whenaformerpatient—aboyshe’dtreatedforsnakebite—broughtheracarvedwoodenbird,Sarahwhispered,“ThisiswhyIstay.”Rainyseasontransformedchallenges.Floodsblockedsupplytrucks,forcingSarahtorationpainkillers.Shecaughttyphoidherself,vomitingbetweenpatientvisits.Onemidnight,villagerscarriedinagirlwithabrokenlegfromafallentree.Paleandshaking,Sarahsetthebonebyflashlight.“Mypainisn’timportant,”shetoldherassistant,watchingraindropstracepathsonthegirl’srelievedface.Now,asSarahsterilized(消毒)toolsinboilingwater,shenoticedadesertrosebloomingbytheclinic’srubblewall.Itspinkpetalsmirroredthesunrise—afragileyetpersistentbeauty,muchlikethelivesshefoughttoprotect.24.HowlonghadDr.SarahworkedinZambiawhenthetribalclasheshappened?A.1year B.1.5years C.2years D.3years25.WhatcausedSarah’sinjuryduringthetribalclashes?A.Directhitbyathrownstone B.FlyingglassfrombrokenwindowsC.Gunfirewhileseekingshelter D.Collapseofthestorageroom26.WhydidSarahcontinueworkingwhilesickwithtyphoid?A.Shewantedtoavoidcriticism.
