运用逻辑的力量征服新托福口语逻辑的力量是指在进行口语回答的过程中，通过用一些路标词或特定句型，使口语录音在内容上体现出清晰的逻辑层次感。根据新托福口语官方评分细则，话题发展（Topicdevelopment）作为四大评分标准之一，具体考察的就是考生清楚陈述或组织语言的能力。一、概念解释从交流角度出发，说话者在发言的过程中使用的“信号弹”被证明能大大提高听者对所听内容的理解或把握度。新托福口语六个问题的后四个都属于综合题（IntegratedSpeakingTasks），能否对阅读和听力材料的重要信息进行合理转述是评分的一项重要指标。其中的Task4，是要求用听力中的具体例子来解释阅读中所涉及的某一抽象概念。考官在评分时，会以此为要求，着重关注考生是否在录音中按要求完成了“解释”这一任务。作为考生，当然就要故意去释放一些“信号弹”，引导考官快速理解自己的答案，识别出答案中符合要求的部分，进而给出相应得分，这才算是力气用在了刀刃上。那么如何做到这一点，到底什么是信号弹？读到这里，相信大家都已经有了答案，那就是逻辑词的使用，包括表示句与句之间让步转折、因果、递进、举例、解释、条件、比较和对比等关系的词。由此就产生出相应的几大状语从句。需要提出的是，由于Task4话题会有不同，那么答题过程中用到各种状语从句的概率也就不同，切不可一概而论。下面，通过两个不同类型的Task4考题实例，讲解以上从句的用法，以此体现以状语从句在新托福口语答题中的重要作用。Forthousandsofyears,humanshavebeenabletodomesticate,ortame,manylargemammalsthatinthewildlivetogetherinherds.Oncetamed,thesemammalsareusedforagriculturalworkandtransportation.Yetsomeherdmammalsarenoteasilydomesticated.Agoodindicatorofananimal’ssuitabilityfordomesticationishowprotectivetheanimalisofitsterritory.Non-territorialanimalsaremoreeasilydomesticatedthanterritorialanimalsbecausetheycanliveclosetogetherwithanimalsfromotherherds.Asecondindicatoristhatanimalswithahierarchicalsocialstructure,inwhichherdmembersfollowaleader,areeasytodomesticate,sinceahumancanfunctionasthe“leader.”听力材料：Sowe’vebeendiscussingthesuitabilityofanimalsfordomestication...particularlyanimalsthatlivetogetherinherds.Now,ifwetakehorses,forexample...inthewild,horsesliveinherdsthatconsistofonemaleandseveralfemalesandtheiryoung.Whenaherdmoves,thedominantmaleleads,withthedominantfemaleandheryoungimmediatelybehindhim.Thedominantfemaleandheryoungarethenfollowedimmediatelybythesecondmostimportantfemaleandheryoung,andsoon.ThisiswhydomesticatedhorsescanbeharnessedoneaftertheotherinaroThey’re“programmed”tofollowtheleadofanotherhorse.Ontopofthat,youoftenfinddifferentherdsofhorsesinthewildoccupyingoverlappingareas—theydon’tfightoffotherherdsthatenterthesameterritory.Butit’sexactlytheoppositewithananimalliketheuh,theantelope...which...well,antelopesareherdanimalstoo.Butunlikehorses,amaleantelopewillfightfiercelytopreventanothermalefromenteringitsterritoryduringthebreedingseason,OK—verydifferentfromthebehaviorofhorses.Trykeepingacoupleofmaleantelopestogetherinasmallspaceandseewhathappens.Also,antelopesdon’thaveasocialhierarchy—theydon’tinstinctivelyfollowanyleader.Thatmakesitharderforhumanstocontroltheirbehavior.问题：Theprofessordescribesthebehaviorofhorsesandantelopeinherds.Explainhowtheirbehaviorisrelatedtotheirsuitabilityfordomestication.参考答案：Accordingtothelecture,herdanimalscanbeeasilydomesticatediftheyhaveahierarchicalsocialstructureandarenotterritorial,andthatthisiswhyitiseasiertodomesticatehorsesthanantelopes.Asintheexampleofhorses,theirhierarchicalsocialstructuremakesthemwillingtofollowoneanother...
