B.Advancement.C.Expansion. D.Revival.答案:D解析:詞義猜測題。根據(jù)畫線詞上文中的“Bynaturallyfeastingoncrabs,theottershavehelpedasignificantregrowthofplantlife.”可知,因為海獺以濱蟹為食,從而有助于植物的再生。畫線詞resurgence意為“復(fù)蘇”,D項與畫線詞意相近。故選D。3.Whatistheauthor'spurposeinquotingLekeliaJenkins?A.Tohighlighttheimportanceofcoastalmarshes.B.Tointroduceanewresearchstudyonseaotters.C.Todemonstratethepracticalbenefitsofseaotters.D.Toemphasizetheneedforincreasedconservationefforts.答案:C解析:推理判斷題。根據(jù)文章第四段中的“Sherevealsmarshrestorationalsohelpspeoplebyreducingflooding.‘Suddenly,seaottersgofromjustcutethingsweliketosomethingthatcanprotectourlivelihoodsandourproperties.’”可推知,作者引用科學(xué)家LekeliaJenkins的話是為了展示海獺(對人類)的實際益處(比如減少洪水災(zāi)害)。故選C。4.Whatmessageisconveyedfromseaotters'impact?A.Thenecessityforcontrolledhunting.B.Theinterconnectednessoftheecosystem.C.Thedrawbacksofwildlifereintroduction.D.Theneedforhumaninterventioninnature.答案:B解析:推理判斷題。通讀全文可知,文章通過說明海獺對沿海生態(tài)系統(tǒng)的影響,傳遞出“生態(tài)系統(tǒng)的相互關(guān)聯(lián)性”這一信息。故選B。B(2025·青島高三檢測)AnancientLatinproverbsays“Aquilanoncapitmuscas”—eaglesdon'thuntflies—meaningthatimportantonesshouldn'tconcernthemselveswithsmall,insignificantmatters.ButthelionsinEastAfricashouldconcernthemselveswiththeseeminglyinsignificantants,becausetheseantsarechangingtheirlifestyles.Thestorystartswiththeacaciatrees(金合歡樹)inanAfricanwildlifeareaincentralKenya.Someoftheseacaciatreesprovidefoodandshelterforspecificantspecies,whichinturndefendthetreesagainstherbivores(食草動物).Theantsareactivelyattackinganddrivingawayherbivoresthatattempttofeedonthetrees'leaves.Thisishighlyeffective;theantsnotonlyphysicallyharmtheherbivoresbutalsoreleasechemicalsthatcandeterotherpotentialattackers.Buttheseantsareintrouble.Anotherspeciescalledthe“big-headed”antisdestroyingentiregroupsoftree-protectingants.This,inturn,setsoffanentirechainofeventsthatendsupinfluencingwhenandhowlionscanhunt.Thisantinvasionaffectsonethingaftertheother.Itleavestheacaciatreesdefenselessagainstherbivores,especiallyelephants.Theelephantscomeinandeattheacaciasatfivetoseventimestherateobservedinuninvadedareas.Thelions,whilehuntingforfood,havenomoretreestouseforhiding.Thisreducedtreecovermakeslionslesssuccessfulathuntingandpushesthemtofinddifferentareastohuntin.“ThesetinyinvadersarepullingonthetiesthatputanAfricanecosystemtogether,determiningwhoiseatenandwhere,”saidToddPalmer,anecologistfromFlorida.Thelions,whicharealreadyendangered,aremanagingtocopewiththisbynolongerfocusingtheirattentiononzebras.Thezebras,ofcourse,canseethemmuchbetterontheapproachgiventhelackofcover.Instead,theyaretargetingwaterbuffalo.Butthisalsoisn'ttheendofthestory.Whoknowswhatthelions'changingstrategywillmeanfortheecosystemdowntheline?【語篇解讀】本文是一篇說明文。文章主要介紹了小螞蟻如何影響?yīng){子的捕獵方式。5.Whatdoestheunderlinedword“deter”inParagraph2mean?A.Direct. B.Discourage.C.Identify. D.Seek.答案:B解析:詞義猜測題。根據(jù)畫線詞上文中的“whichinturndefendthetreesagainstherbivores(食草動物).Theantsareactivelyattackinganddrivingawayherbivoresthatattempttofeedonthetrees'leaves.Thisishighlyeffective;theantsnotonlyphysicallyharmtheherbivores”可知,螞蟻對金合歡樹具有保護作用。由此可知,螞蟻還釋放出可以阻止其他潛在攻擊者的化學(xué)物質(zhì)來保護金合歡樹。deter意為“阻止”,B項與畫線單詞意思相近。故選B。6.Whatroledotheelephantsplayinthechainreaction?A.Cooperatingwiththe“big-headed”ants.B.Damagingthehidingplaceforlions.C.Protectingtheacaciasfromherbivores.D.Startingoffthedisturbanceofthechain.答案:B解析:細節(jié)理解題。根據(jù)第四段中的“Theelephantscomeinandeattheacaciasatfivetoseventimestherateobservedinuninvadedareas.Thelions,whilehuntingforfood,havenomoretreestouseforhiding.”可知,大象吃金合歡樹的速度是未被入侵地區(qū)的五到七倍。在尋找食物的時候,獅子沒有更多的樹可以用來躲藏。由此可知,在食物鏈中,大象破壞了獅子的藏身之處。故選B。7.Theauthormentionslions,zebrasandwaterbuffalotoshowthat.A.a(chǎn)nimalsfallvictimtobiggeronesB.theecologyisontheroadtorecoveryC.a(chǎn)nimalsarecorrelatedintheecosystemD.speciesarefirmlypositionedinthefoodchain答案:C解析:推理判斷題。根據(jù)倒數(shù)第二段“‘ThesetinyinvadersarepullingonthetiesthatputanAfricanecosystemtogether,determiningwhoiseatenandwhere,’...”和最后一段中的“Thelions...aremanagingtocopewiththisbynolongerfocusingtheirattentiononzebras.Thezebras,ofcourse,canseethemmuchbetterontheapproachgiventhelackofcover.Instead,theyaretargetingwaterbuffalo.”可知,這些螞蟻的入侵導(dǎo)致金合歡樹被大量吃掉——這使得獅子在狩獵時失去遮蔽,并導(dǎo)致以斑馬為食的獅子轉(zhuǎn)而獵殺水牛。由此可推知,作者提到獅子、斑馬和水牛是為了說明動物在生態(tài)系統(tǒng)中是相互關(guān)聯(lián)的。故選C。8.Whatisthetextmainlyabout?A.Whatecologistsfindaboutanimals.B.WhyAfricanlionsareendangered.C.Howtinyantsaffectthewaylionshunt.D.HowthelawofthejungleworksinAfrica.答案:C解析:主旨大意題。通讀全文,尤其根據(jù)文章第一段中的“ButthelionsinEastAfricashouldconcernthemselveswiththeseeminglyinsignificantants,becausetheseantsarechangingtheirlifestyles.”可知,文章主要介紹了小螞蟻是如何影響?yīng){子的捕獵方式的。故選C。Ⅱ.閱讀七選五(本題共5個小題,每小題2.5分,共12.5分)(2024·河北高三下適應(yīng)測試)Tiredoftraditionalchlorinated(含氯的)pools?Considerasaltwaterpool,apopulartrendinrecentyears.Asaltwaterpoolisatypeofswimmingpoolthatusesasaltchlorinegeneratortoproduceitsownsupplyofchlorine.Thismeansinsteadofmanuallyaddingharsh(刺激性的)chemicalstoapool,thegeneratorchangessaltintochlorineandreleasesitintothewaterasneeded.1Theystillcontainlevelsofchlorineandotherminerals,buttheamountissignif
