D．Atravel1．B解析：推理判断题。根据第二段第四句“Oneoftheoaktreesalwaysstartstosheditsleavestwoweeksearlierthantheothers.”可知，三棵橡树中，有一棵总比其他两棵先落叶；结合第三段第一句“Notonlydotreesmaketheirowndecisions,theyalsolearnfromtheirmistakes.”可知，树木能自己做决定。据此可推知，作者提B项正确。2．D解析：推理判断题。根据第三段第一句“Notonlydotreesmaketheirowndecisions,theyalsolearnfromtheirmistakes.”，并结合第三段内容可知，树木不仅能自己做决定，还能从自己的错误中吸取教训。据此可推知，树木适应能力强。根据第四段第一、二句“Buttreesaren’tonlycleverwhenitcomestocaringforthemselvesTheyalsosupporteachotherwheneverthere’stroublebygivingwarningsandeventakingcareofsickandweakconspecificswithnutrients.”可知，树木不仅照顾自己，当遇到时，它们会发出警告，相互支持，甚至照顾生病、虚弱的同类；据此可推知，树木之间互帮互助，故D项正确。3．C解析：词义猜测题。根据第四段尾句“Well，thestumpwasnourishedbyitsneighborswithnutrientsfromtherootsystemandhadbeenforatleast400years！”可知，树桩是由它的邻居从根处给予营养来滋养的；结合第五段第一句“Whydotreesdosuchathing？”和其后的内容可知，该处表示“为什么树木要互相帮助？”C项正确。4．B解析：文章出处题。通读全文可知，本文是一篇说明文，主要介绍了树的智慧：每棵树都有它不B项正确。BWhileelephantsbornwithouttusks(长牙)arenotunheardof,theynormallyformjust2to6percentofthepopulation.HoweverthatisnotthecaseatMozambique’sGorongosaNationalPark,whereanastonishing33percentoffemaleelephantsbornafterthecountry’sendedin1992aretuskless.Whilethatmayappeartobejustacoincidence,JoycePoole,anelephantbehaviorexpert,hasanothertheory.Theresearcherthinkswemaybewitnessingunnaturalevolutionofthespeciesduetotheconstanthuntingofelephantsforvaluableivories.Poolesaysbeforethecountry’s15-year-long,theparkwashometoover4，000elephants.However,bythetimetheendedin1992,about90percentofthemhadbeenkilledforivoriestogetmoney.Ofthelessthan200survivors,over50percentofadultfemaleshadnotusks.Therefore,itisnotsurprisingthatthepark’stusklesselephantpopulationhasgrowngreatly.Thisisnotthefirsttimeresearchershaveobservedagreatchangeinthepopulationofelephants.AtZambia’sSouthLuangwaNationalParkandLupandeGameManagementArea,areaswhichwereheavilyhuntedinthe1970sand1980s,35%ofelephantsof25yearsoldorolderand13%ofthoseyoungerthan25arenowwithouttusks.A2008studypublishedintheAfricanJournalofEcologyfoundthatthenumberoftusklessfemalesattheRuahaNationalParkinTanzaniawentfrom10.5percentin1969toalmost40percentin1989,largelyduetoillegalhuntingforivories.TherecentbanonivoriesinboththeUSandshouldhelpgetridof,oratleastreduce,elephanthunting.However,scientistsarenotsurehowlongitwilltakeforelephantswithahigherrateoftusklessfemalestochangeWhatistheprobablecauseofthephenomenonmentionedinParagraphIllegal

endedin1992,about90percentofthemhadbeenkilledforivoriestogetmoney.”可知，然而在1992年内战结束时，有大约90%的大象因象牙被猎杀，从而获得钱。据此可知，人们猎杀大象是为了通过销售象牙来获得钱，故A项正确。7．C解析：细节理解题。根据第一段的第二句可知，在1992年内战结束时，的Gorongosa33%的雌象生来无长牙；根据第三段尾句“A2008studypublishedintheAfricanJournalofEcologyfoundthatthenumberoftusklessfemalesattheRuahaNationalParkinTanzaniawentfrom10.5percentin1969toalmost40percentin1989,largelyduetoillegalhuntingforivories.”可知，Ruaha196910.5%的C项正确。8．D解析：推理判断题。根据尾段第一句“TherecentbanonivoriesinboththeUSand getridof,oratleastreduce,elephanthunting.”可知，最近和中国都颁布了象牙禁令，这应该有助于消除或至少减少对大象的猎杀；结合该段第二句“However,scientistsarenotsurehowlongitwilltakeforelephantswithahigherrateoftusklessfemalestochangethetrend．”可知，科学家们并不确定对拥有较高比例无长牙雌象的Therewasasurveyofthepeoplewhowerebornfrom1980to2000,askingthemwhattheirmostimportantlifegoalswere.Over80percentsaiditwastogetrich.1We'reconstantlytoldtodevotemoretoourwork,topushharderandtoachievemore.We'regiventheimpressionthatthesearethethingsthatweneedtogoaftertohaveagoodlife.Butisthatthetruth?2Butwhatifwecouldstudypeoplefromthetimewhentheywereteenagersallthewayintooldagetoseewhatreallykeepspeoplehappyandhealthy?TheHarvardStudyofAdultDevelopmentdidit.For75years,they'vetrackedthelivesof724men.Studieslikethisareextremelyrare.Almostallprojectsofthiskindfallapartwithinadecadebecausetoomanypeopledropoutofthestudy.3Ortheresearcherscan'tgettogether.Butthroughacombinationofluckandthepersistenceofseveralgenerationsofresearchers,thisstudyhasSowhathavetheylearned?Theconclusionisthatit'snotwealthorfamethat4They'velearnedthreebiglessonsaboutrelationships.Firstly,peoplewhoaremoresociallyconnectedtofamily,tofriendsandtocommunityarehappierandphysicallyhealthier.Thesecondisthatit'snotjustthenumberoffriendsyouhavebutthequalityofyourcloserelationshipsthatmatters.Andthethirdisthatgoodrelationshipsdon'tjustprotectourbodies.Theycanevenprotectour

解析：根据前文“Therewasasurveyofthepeoplewhowerebornfrom1980to2000themwhattheirmostimportantlifegoalswere.Over80percentsaiditwastogetrich.”可知有一项针对1980年到2000年出生的人的，询问他们最重要的生活目标是什么，超过80%的人说是发家致富。结合选项可知B项“To efamouscamesecond.”符合文意］ 解析：前文说这是事实吗？”G项“Tobefrank,sometimeswealthandfamecanmakepeoplehappy.”说到了名和利，故选G. “Almostallprojectsofthiskindfallapartwithinadecadebecausetoopeopledropoutofthestudy.”可知几乎所有类似的项目在十年内都会分崩离析，因为有太多人退出了这项研C项“或是研究经费枯竭”符合文意。 解析：根据下文“They'velearnedthreebiglessonsaboutrelationships."F项“Itisgoodrelationshipsthatkeepushappierandhealthier.(良好的人际关系让我们更快乐、更健康）”符合文意。 解析：根据前文“Andthethirdisthatgoodrelationshipsdon'tjustprotectourbodies.”A项“Theycanevenprotectourbrains.(它们甚至可以保护我们的大脑）”符They'dbeenon1 (we)netformillionsofyears,but2018wastheyearwhenseveralspecies
