归纳推理题，是对文章内容进行进一步的总结归纳或是深层推理。在把握文章信息的基础上，通过排除法，排除无关项，选出正确答案。例.Increaseinthelevelofhigh-densitylipoprotein(HDL)inthehumanbloodstreamlowerbloodstream-cholesterollevelsbyincreasingthebody’scapacitytoriditselfofexcesscholesterol.LevelsofHDLinthebloodstreamofsomeindividualsaresignificantlyincreasedbyaprogramofregularexerciseandweightreduction.Whichofthefollowingcanbecorrectlyinferredfromthestatementsabove?A.Individualswhoareunderweightdonotrunanyriskofdevelopinghighlevelsofcholesterolinthebloodstream.B.Individualswhodonotexerciseregularlyhaveahighriskofdevelopinghighlevelsofcholesterolinthebloodstreamlateinlife.C.Exerciseandweightreductionarethemosteffectivemethodsofloweringbloodstreamcholesterollevelsinhumans.D.Aprogramofregularexerciseandweightreductionlowerscholesterollevelsinthebloodstreamofsomeindividuals.E.Onlyregularexerciseisnecessarytodecreasecholesterollevelsinthebloodstreamofindividualsofaverageweight.文章翻译：增加人体血液当中HDL的含量可以通过提高人体排出胆固醇的能力而讲题人体内胆固醇的含量。血液当中HDL的含量可以通过运动和减重得到提高文章解析：对文章叙述进行总结就是运动&减肥>>HDL升高>>胆固醇下降选项分析：A.不足重的人没有得高胆固醇的风险。Weightreduction不等于underweight。无关项。B.不经常锻炼的人有得高胆固醇的风险。锻炼会降低胆固醇，不代表不锻炼的人胆固醇一定会高。无关项。C.运动和减肥是最有效降低胆固醇的方法。Most意味着文章中应该会有多于三者的比较，但是文章中并没有出现三者以上的比较，所以无关项。D.经常锻炼和减肥会降低人体血液当中胆固醇的含量。正好是我们总结出来的关系。正确答案。E.经常锻炼是唯一可以降低人体胆固醇的方法。文中没有提到唯一性，无关项。例1.所有的人都去了。我是人。公共信息：人直接推结论：我去了。例2.被南非的蚊子叮咬之后，有可能换上疟疾。如果不用WDSCJ来治疗疟疾的话，就会引起严重的病发症。WDSCJ的价格很高，绝大多数的人都不用这样的药物来治疗。下列的哪一项一定为真？A.绝大多数人会得严重的病发症；B.WDSCJ能够加快并发症消失的过程；C.有些人被南非蚊子叮咬之后，有可能换上疟疾；D.绝大多数被南非蚊子叮咬之后，不可能有严重的病发症状；E.WDSCJ是十年来最有效的药物；例3.Tobementallyhealthy,peoplemusthaveself-respect.Peoplecanmaintainself-respectonlybycontinuallyearningtherespectofotherstheyesteem.Theycanearnthisrespectonlybytreatingtheseothersmorally.Whichofthefollowingconclusionscanbeproperlydrawnfromthestatementsabove?A.Peoplewhoarementallyhealthywillbetreatedmorallybyothers.B.Peoplewhoarementallyhealthywillhavetreatedmorallythosetheyesteem.C.Peoplewhoarementallyhealthymusthaveself-respectinordertobetreatedmorallybyothers.D.Peoplecanexpecttobetreatedmor
