【解题导语】 本文主要介绍了科学家通过实验对乌鸦智商进行的研究。
1.HowdidthecrowsgetthesnackinSarah’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.Theydroppedobjectsonlyintonarrowtubes.
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.Whatdoesthetextmainlyfocuson?
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.Crowsunderstandwaterdisplacementcompletely.
C.Chimpsandchildrenaremuchsmarterthancrows.
D.ThestoryofTheCrowandthePitcherlacksevidence.
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。

【解题导语】 本文主要介绍了一项新的科学研究。
研究表明植物会对外在威胁相当警觉,会自动作出反应进行自我保护。
5.JohnOrrocksprayedaliquidontosoilneartomatoplantsto________.
A.makethemgrowbetter
B.givethemawarning
C.keepplanteatinganimalsaway
D.informplanteatinganimalsofdanger
B 解析:
推理判断题。
根据第二段最后一句“Wejustgavethemcuesthatsuggestedanattackwascoming,andthatwasenoughtocausebigchangesintheirchemistry.”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’simpactonanotherpotentialthreat”呼应,故选B。
6.WhyistheexampleofcaterpillarsmentionedinParagraph3?
A.Tointroduceanotheranimal.
B.Toconfirmtheresultofthestudy.
C.Toappealtopeopletoprotectanimals.
D.Toanalyzedifferentresistancechemicals.
B 解析:
推理判断题。
根据第三段第一句“InitiallyOrrockfoundthisdefenseworkedagainstsnails;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.GreedyAnimals
C.ASnail’sApproachD.ADefenseAttack
A 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。
