2.因果关系错误:
不是由于结婚才导致他取得科技进步。
时序因果类错误。
3.由个体推整体。
广告练习:
喝了哇哈哈,吃饭就是香。
条件不充分
要想皮肤好,早晚用大宝。
条件不充分。
牙好胃口就好:
样本小,条件不充分。
二.Argument整体结构
第一段:
开头段。
主要是归纳论点,说明论点有问题,存在逻辑漏洞,准备发起进攻。
第二段和第三段甚至第四段:
分类别去攻击各个逻辑错误。
第五段:
结尾段。
作者的结论似乎是合理的,但是通过论证,不是这样的。
因此作者在做出决定之前,应该还要考虑其他情况。
三.如何写开头段?
例.重复结论+扼要重述论据+转折(总论)
InthismemothevicepresidentofNature'
sWayCNW),achainofstoressellinghealthfoodandhealth-relatedproducts,recommendsopeningastoreinPlamesville.TosupportthisrecommendationthevicepresidentcitesthefollowingfactsaboutPlainesville:

四.开头段的写法
Merelybasedonunfoundedassumptionanddubious(suspicious)evidence,thestatementdrawsaconclusionthat_____.Tosubstantiate(support)theconclusion,thearguerpointsoutevidencethat_____.Inaddition,heindicatesthat_____.Furthermore,hecitestheresultofarecentsurveyinsupportofthisrecommendation.Atfirstglance,theauthor’sargumentappearstobesomewhatconvincing,butfurtherreflectionrevealsthatitomitssomesubstantialconcernsthatshouldbeaddressedtosubstantiatetheargument.Inmypointofview,thisargumentsuffersfromNlogicalflaws.
1.先在开头段指出原文的conclusion
2.指出作者引用哪些evidenceorassumption
3.指出存在几个flaw
Inthisargument,theauthorconcludesthat,tosupporthisconclusion,hepointsoutthat____.Inaddition,heinfersthat____.Furthermore,thearguersitesasatypicalexampleinsupportofhisrecommendation.However,thisalone/onlythisdonotconstitutealogicalargumentinfavorofitsconclusion,andfailstoprovideconvincingsupport,makingthisargumentsoundandinvulnerable.
五.如何写正文段
逻辑错误的攻击顺序
1.按照逻辑错误出现的顺序,分段顺序攻击。
(不特别推荐)
2.按照逻辑错误主次进行分段攻击
3.让步式攻击法(重点)
1)sevenyearsago外推类错误
2)sincethen时序性因果错误
3)weshouldadoptourownsetof…错误类比
六.如何写结尾段
1.不要概括作者的某种结论
2.对于无根据的调查和比较是不能说明任何问题。
七.结尾段的具体写法
Tosumup,thisarguerfailstosubstantiateitsclaimthat_____,becausetheevidencescitedintheanalysisdoesnotlendstrongsupporttowhatthearguermaintains.Tomaketheargumentmoreconvincing,thearguerwouldhavetoprovidemoreinformationwithregardto_____.Additionally,hewouldhavetodemonstratethat_____.Therefore,iftheargumenthadincludedthegivenfactorsdiscussedabove,itwouldhavebeenmorethoroughandlogicallyacceptable.
八.各个逻辑错误的攻击方法和语言重点。
调查类错误包含子类多,存在题目量大。
所以重要。
标志词:
1.Survey/Study:
核心攻击两大问题:
a.样本质量b.样本数量
(1)Procedure
A.Selectivesample选择性、片面性样本(片面的、特定人群的,最后缺得到了普遍性结论。
)
Eg.题库8

Discusshowwellreasoned...etc.
无法判断1200人调查能否代表全部工人看法。

调查类错误攻击思路:
反过来攻击。
逆向说:
样本选择随机是具有代表性的。
B.Quantityofthesample
样本数量少,要受到质疑;
数据多也要质疑,比如1万人,看似多,但只占0.1%。
a.样本数量要大b.样本要随机。
题库25题。
重点。

“Twoyearsago,CityLwaslisted14thinanannualsurveythatrankscitiesaccordingtothequalityoflifethatcanbeenjoyedbythoselivinginthem.ThisinformationwillenablepeoplewhoaremovingtothestateinwhichCityLislocatedtoconfidentlyidentifyoneplace,atleast,whereschoolsaregood,housingisaffordable,peoplearefriendly,theenvironmentissafe,andtheartsflourish.”Discusshowwellreasoned...etc.
作者没有说调查了多少城市,调查的城市越多,论证越有力,反之也成立。
模板:

(2)Resultofthesurvey
A.Dothestatisticsmakeanymeaningfulness?
数据是否有意义?
数据即使准确,但是有没有意义?
题库17题
Thefollowingappearedinanarticleinaconsumer-productsmagazine:
“Twooftoday’sbest-sellingbrandsoffull-strengthprescriptionmedicationforthereliefofexcessstomachacid,Acid-EaseandPepticaid,arenowavailableinmildernonprescriptionforms.Doctorshavewritten76millionmoreprescriptionsforfull-strengthAcid-Easethanforfull-strengthPepticaid.SopeoplewhoneedaneffectivebutmildernonprescriptionmedicationforthereliefofexcessstomachacidshouldchooseAcid-Ease.”
Full-strengthmilder错误类比
作者说:
强力的AE比强力的P多卖出,AE效果比P要好。
驳斥:
即使强力的AE比强力的P要好,但是仍然不能得出温和的AE比温和的P要好。
虽然AE比P多卖,但并不一定就是AE比P要好。
有可能AE上市早等等原因。
医生可能因为疗效以外的其他原因偏好AE,如生产商、价位等。
题库43题:
Thefollowingappearedinanarticleinthehealthsectionofanewspaper:
“Thereisacommonmisconceptionthatuniversityhospitalsarebetterthancommunityorprivatehospitals.Thisnotionisunfounded,however:

医生人数少不一定医术差;
治愈率与所接触病人情况联系大。
B.Arethestatisticsmisleadinglyvague?
只要出现数据,绝对有问题。
①攻击“无相对比值”(虽然数量大,但是只占很小部分)
Theargumenttellsusthat“many”(anumberof)_____.However,thespeakerfailstoindicatethepercentageof_____,sothisevidenceisfartoovaguetobemeaningful.
②攻击“无绝对数值”(虽然比例大,但是总量小。
比如只有10个人投票。
Theauthorfailstoprovideinformationregardingtheabsolutenumberof____.
题库39题

“Onaverage,9outofevery1,000passengerswhotraveledonAviaAirlineslastyearfiledacomplaintaboutourbaggage-handlingprocedures.Thismeansthatalthoughsome1percentofourpassengerswereunhappywiththoseprocedures,theoverwhelmingmajoritywerequitesatisfiedwiththem;
thusitwouldappearthatareviewoftheproceduresisnotimportanttoourgoalofmaintainingorincreasingthenumberofAvia’spassengers.”
攻击:
缺乏绝对数值。
如果乘客量大,那么不满意的乘客数量很多。
仍然能反映出航空公司的服务质量差。
C.Respondents
Therespondentsmustbestatisticallysignificantinnumberandrepresentativeoftheoverall_____.
回应者问题。
所有的回应者都无法代表被调查人,更无法代表整体被调查对象。

2.SufficientEvidenceandNecessaryCondition
(1)SufficientEvidence攻击对方条件不充分。
A足以导致B发生,但A不是B发生的完备条件。
B的发生还依赖于其他因素CEF等才能发生。
攻击时:
指出A是一个因素但是不充分,并指出B发生的其他因素。
