fthoughtfulnessinchoosingagiftC、thatone’sloveforotherscanbestbedemonstratedbygiftsD、thatofferingagiftbenefitsboththegiverandthereceiver標準答案：D知識點解析：本文在首段首句、第2段首句、第3段末句，以及末段第2句不斷強調“贈送禮物時對贈送者和接受者而言都是一種快樂”這個主題，由此可見，本題應選D。DuringthenextseveralweeksIwentcompletelytothewolves.Itookatinytentandsetitupontheshoreofbay.ThebigtelescopewassetupinthemouthofthetentinsuchawaythatIcouldobservethewolvesbydayornight.QuitebyaccidentIhadpitchedmytentwithintenyardsofoneofthemajorpathsusedbythewolves.ShortlyafterIhadtakenupresidence,oneofthewolvescamebackanddiscoveredmeandmytent,buthedidnotstoporhesitateinhispace.Later,oneormorewolvesusedthetrackpastmytentandneverdidtheyshowtheslightestinterestinme.Ifeltuncomfortableatbeingsototallyignored.ThenextdayInoticedamalewolfmakeboundarymarkersbypassingwaterontheroundsofhisfamilylands.OnceIhadbecomeawareofthestrongfeelingofpropertyrightswhichexistedamongthewolves,Idecidedtousethisknowledgetomakethematleastrecognizemyexistence.Oneevening,aftertheyhadgoneofffortheirregularnightlyhunt,Istakedoutapropertyclaimofmyown,includingalongsectionofthewolves'path.Inordertoensurethatmyclaimwouldnotbeoverlooked,Imadeapropertymarkonstones,dumpsofmoss,andpatchesofvegetationwithalotoftea.Beforethehunterscameback,taskwasdone,andIretired,somewhatexhausted,toobserveresults.Afewminuteslatertheleadingmaleappeared.Asusualhedidnotbothertoglanceatthetent,butwhenhereachedthepointwheremypropertylineintersectedthetrail,hestoppedasabruptlyasifhehadrunintoaninvisiblewall.Cautiouslyheextendedhisnoseandsniffedatoneofmymarkedbushes.Afteraminuteofhesitationhebackedawayafewyardsandsatdown.Then,helookeddirectlyatthetentandatme.HisglareseemedtobecomefiercerasIattemptedtostarehimdown.Thesituationwasbecomingintolerable.TobreaktheimpasseIturnedmybackonthewolf.Thenbriskly,andwithanairofdecision,heturnedhisattentionawayfrommeandbeganasystematictourofthearea.Ihadstakedoutasmyown.Ashecametoeachboundarymarkerhesniffeditonceortwice,thencarefullyplacedhismarkontheoutsideofmine.26、Theauthorismostprobablya______.A、hunterB、biologistC、journalistD、traveler標準答案：B知識點解析：文章第1段中作者指出用望遠鏡來觀察狼群，而從文章可以看出作者對狼的生活習性很了解，在倒數(shù)第2段作者還敢盯著狼想要把它嚇退，從這些信息都可以推斷作者很可能是一個生物學家，具有較多的專業(yè)知識，因此本題選B。27、Whydidthewolvesignoretheauthor’spresence?A、Becausehistentwasoutofthewolves’estateboundaries.B、Becausetheauthorhasjustarrivedatthespot.C、Becausethewolvesweretoobusytonoticehim.D、Becausethewolveswereafraidofstrangers.標準答案：A知識點解析：在第2段狼群對作者的存在并不在意，但到了第4段末句，狼盯著作者的帳篷，這其中的變化就在于第3段描寫的作者在狼群的領土范圍內留下了自己的記號，由此可推斷，在此之前狼群之所以忽視他的存在就是因為他不在狼群的領土范圍之內，即選項A為本題答案。28、WhichofthefollowingisTRUEaboutthewolvesaccordingtothepassage?A、Thewolvesdonotstartattackinghumansunlessirritatedbyhumans.B、Thewolvesgohuntingatnightandgobacktothedensatdawn.C、Thewolvesdonotrelyontheirsighttorecognizeboundaries.D、Thewolvesmarktheirfamilyboundariesbymeansofwater.標準答案：C知識點解析：第4段首句和末段末句中的sniff一詞都表明狼主要以嗅的方法確認領地，因此選項C是正確的說法。29、Thephrase"breaktheimpasse"(Line2,Para.5)isclosesttothemeaningof"______".A、avoidbeingattackedB、breaktheiceC、triggerhostilityD、defeattheenemy標準答案：B知識點解析：從倒數(shù)第2段第2句中的intolerable一詞可以知道作者和狼當時處在一個僵持的局面，作者對此已經覺得難以忍受，因此主動先采取行動，且的是為了試探狼的舉動，由此可見，選項B是最貼切的理解。30、Whichofthefollowingbestexplainsthereasonwhytheauthorstakesoutanareaofhisown?A、Hethoughtitbettertobestaredatthantobeignored.B、Hedidn’twantthewolvestousethetrackpasthistent.C、Hewantedthewolvestotakenoticeofhisexistence.D、Hewantedtofindouthowfiercethewolf’sglarewas.標準答案：C知識點解析：從第3段第2句開始，作者描述了如何劃定自己的領土，所有這些描述都是圍繞該段首句展開的，選項C就是本題答案。大學英語六級改革適用（閱讀）模擬試卷第2套一、長篇閱讀(本題共30題，每題1.0分，共30分。)TheHealthBenefitsofDrinkingWater—Isbottleddrinkingwaterhealthierthanfilteredtapwater?[A]Waterisakeyingredientinahealthydietandlifestyle.Therearemanyhealthbenefitsofdrinkingwater.Ithelpsflushimpuritiesandtoxinsoutofoursystems.Itaidsinthedeliveryofoxygenandnutrients.Infact,nearlyeverysysteminourbodiesreliesonwaterforproperfunctioning.Butwhatwillhappenifthewateryoudrinkeverydayisunhealthy?[B]Inpastdecades,concernsabouttapwateranditsimpactonoverallhealthledsomepeopletoturntobottleddrinkingwaterinsteadHowever,inthosedays,therewerefewchoicesofbottledwaters.Youcouldpaytohaveacompanydeliverlargebulkyplasticbottlesofwaterforthewatercooler.Oryoucouldpurchasegallonjugsofdistilledor"drinkingwater"atthegrocerystore.[C]Inrecentyears,therehasbeenanexplosioninthenumberofdifferentbottledwatersavailable,withbigdistributorssuchasCokeandPepsijumpingonthebandwagon.ButarebottleddrinkingwaterslikeCoke'sDasanibrand,Pepsi'sAquafina,orWal-Mart'sstorebrandreallyanyhealthierthanyourtapwater?Orwouldyoubebetteroffwithadrinkingwaterfiltrationsystem?[D]Aswehavelearnedmoreaboutthewaterwedrink,thetechnologybehinddrinkingwaterfiltersandpurificationsystemshasimproveddramatically.Therearefilterstoremoveimpurities,chemicals,heavymetals,bacteriaandmosteverycontaminantyoucanthinkof.Withtherightsizeandfiltercombinationforyourspecifichome,yourtapwatercanbeexceptionallypureandhealthy.[E]Drinkingwaterfiltrationsystemshavealsobecomemoreaffordableandeasytouse.Althoughtheinitialcostofawholehousesystemusuallyamountstosever
