Sarah’sexperiment?A．Bybreakingthetube.B．Bydroppinginerasers.C．Bystandingonthewood.D．Byremovingthewood.B解析：

细节理解题。根据第三段最后一句“Thecrowsfoundoutthattheycoulddroptheerasersintothetubesinordertoraisethewaterlevelandgettheirsnack.”可知，乌鸦能够把橡皮擦扔到管里，使水

位升高，然后吃到零食。所以选B项。2．Whatdoestheauthormeanby“thebirdshandledawkwardly”inParagraph4?A．Theywereunabletotelldifferentshapes.B．Theydro

ppedobjectsonlyintonarrowtubes.C．Theywerenotawareofthesnackatfirstsight.D．Theymostlyavoidedtheeasierwaytogetthesnack.D解析：推理判断题。从第四段可知，实验中

的乌鸦在面对粗细不同的管子时，虽然只需往细管里投两次物体就可以够到零食，而需往粗管里投大约七次物体才能够到零食，但是乌鸦往往先去粗管那边，而没有选择更容易获得零食的细管。由此可推知，画线部分是说它们通常没有选择更容易的方式得到零食。3．Whatdoesthetextm

ainlyfocuson?A．StoriesofAesop’sFables.B．Thedevelopmentofcrows.C．Crows’intelligence.D．Human­animalcommunication.C解析：主旨大意题

。根据第二段最后一句“Theresultssuggestthatthebirdsare,atleastinsomeaspects,assmartasfirst­graders.”以及下文中的实验可知，整篇文章都是围绕乌鸦的智商问题

来展开的。4．Whatdoweknowaboutcrowsinthepassage?A．Crowsarealmostascleverasfirst­gradersinsomerespects.B．Crowsunderstand

evidence.A解析：推理判断题。根据第二段最后一句“Theresultssuggestthatthebirdsare,atleastinsomeaspects,assmartasfirst­graders.”可

知，乌鸦在一些方面几乎跟一年级学生一样聪明。B(2020·潍坊统一考试)Plantscannotrunorhide,sotheyneedotherstrategiestoavoidbeingeaten.Somecurlupthei

作出反应进行自我保护。5．JohnOrrocksprayedaliquidontosoilneartomatoplantsto________．A．makethemgrowbetterB．givethemawarningC．keepplant­eatinganimalsawayD．informpl

ant­eatinganimalsofdangerB解析：推理判断题。根据第二段最后一句“Wejustgavethemcuesthatsuggestedanattackwascoming,andthatwasenoughtoca

usebigchangesintheirchemistry.”可推知，JohnOrrock在西红柿植株附近的泥土上喷洒液体的目的是给予植物一种警告，让它们能够产生自我保护性反应，且其与第三段第一句中的“histeammeasuredtheslimywarning’simp

actonanotherpotentialthreat”呼应，故选B。6．WhyistheexampleofcaterpillarsmentionedinParagraph3?A．Tointroduceanoth

eranimal.B．Toconfirmtheresultofthestudy.C．Toappealtopeopletoprotectanimals.D．Toanalyzedifferentresistancechemicals.B解析：推理判断题。根据第三段第一句“InitiallyOr

rockfoundthisdefenseworkedagainstsnails；inthelateststudy,histeammeasuredtheslimywarning’simpactonanotherpotentialthreat.”可推知，文

章中提到毛虫的例子是为了验证研究的结果，故选B。7．WhatdoesRichardKarbanreallywanttoknow?A．Howtomatoplantsbecomeawareofdanger

.B．Whatthechemicalsinthesnailslimeare.C．Whethertheresearchisofpracticalvalue.D．Whatthefindingoftheresearchis.A解析：推理判断题。根据第四段最后一句

“‘Theresearchwascomprehensive，’headds，‘buthewondershowthetomatoplantsfeltchemicalsinsnailslimethatneveractuallytouchedthem.’”，并结合对最后一段的整体理解

可推知，RichardKarban实际上想了解的是西红柿植株是如何意识到危险的，故选A。8．Whatcanbeasuitabletitleforthetext?A．WatchfulPlantsB．GreedyAnimalsC．ASnai

l’sApproachD．ADefenseAttackA解析：标题归纳题。根据文章中的关键词plant，并结合对全文的整体理解可推知，本文主要讲述的是有关植物的科学研究，研究发现植物有对外在威胁或攻击的自我保护性反应，故选A。Ⅱ.完形填空(2020

agree“同意”。2．A.gentlyB．gratefullyC．humorouslyD．eagerlyD解析：根据上文“I______itwassomethingtodowithanaccidentIhadre
