七选五解题技巧在做七选五时，应该注意以下四点：1.把握文章主题句和结尾句2.特别注意句句之间、段段之间的连接词3.答案模糊时，联系上下文，排除干扰项4.检查时，代入选项看是否通顺有逻辑性的解题步骤：1.先读题目要求的第一句,初步了解主题2.利用语法知识确定句子缺失成分3.重点阅读空格前后的句子利用各种衔接手段选择正确的选项填入空格4.认真阅读选项,并找出关键词与空格进行搭配常见的六种指代方法：人们讲话或写文章时，常常要把前后讲的或写的内容加以联系。联系的方式有几类，它们为语言的应用提供粘合(cohesion)。1.返指(referringback)已经提及的事项。2.预指(referringforward)将要说及的事项。返指方法一：使用名词词组返指前文中的具体名词，避免重复，并从意思上进行具体解释。返指方法二：在名词（或名词词组）前使用the这一特指限定词，返指前文中提到的名词或词组。返指方法三：使用副词来指代前文中提到或讨论到的时间。返指方法四：用this；that和他们的复数形式these和those清楚地返指前文中提到的事物和事实；用such作为限定词或形容词返指刚刚提及的事物。返指方法五：所谈的行为或情况在前面已经提及时，可用so来替代。返指方法六：使用人称代词和物主代词。在A－F备选句中一旦出现代词，就应该在前文中找到对应。否则该句就不能成为答案。常见的几种句型关系1.并列关系:空格前后的句子基本属于同一主题,没有发生转折Allbankspayinterestonsavingsaccounts.____1____Banksalsopayinterestatdifferenttimes.____2____Suppose,forexample,thatonJanuary1,youdeposited$1,000inabankthatpaid41/2percentinterestsemiannually.ByJuly1,youwouldhaveearned$22.50interest.Thisinterestwouldautomaticallybecreditedtoyouraccount;andofyouleftitinthebank,alongwithyouroriginaldeposit,youwouldreceiveintereston$1,022.50forthenextsix-monthperiod.Thatis,yourinterestwouldbecompounded.A.Themajorityofthempaysemiannually,thatis,everysixmonths.B.Theinterestratevariesfrombanktobank,butthegeneralrangeisfrom41/2to6percent.C.Thismeansthatpassbookcontainsanactualrecordofalltransactionsmadeandthatyouknowtheexactamountofsavingsyouhaveatanyonetime.D.Oneoftheseischeckingaccounts.E.Firstyouwouldbeaskedtofilloutasignaturecard.F.Butmostbankspayinterestattheendofayear.2.总分关系(举例关系)Amodernbankprovidesmanyservicesotherthancheckingaccounts.____1____Ifyouwenttoabanktoopenasavingsaccount,youwouldgothroughalmostthesameproceduresfollowedinapplyingforacheckingaccount.A.Butthemajorityofthempaysemiannually,thatis,everysixmonths.B.Theinterestratevariesfrombanktobank,butthegeneralrangeisfrom41/2to6percent.C.Thismeansthatpassbookcontainsanactualrecordofalltransactionsmadeandthatyouknowtheexactamountofsavingsyouhaveatanyonetime.D.Oneoftheseischeckingaccounts.E.Firstyouwouldbeaskedtofilloutasignaturecard.F.Oneofthemostimportantoftheseisregularpassbooksavings.3.转折关系:空格前后的句子在含义上发生转折ElectricityisasignificantsourceofexportincomeforCanada.____1____Butinthe1970s,CanadianexportsrosesharplytoaddresstheU.S.demandforcheaperandmorereliable.A.Besides,electricityfromcoalandnuclearis50%to75%cheaperthanmanyotherindustrialnations.B.Generatedprimarilybywater,ourpowersupplieshaveattractedandsupportedenergyintensiveindustriessuchasmining.C.Italsoranksamongthetopthreeelectricityproducersintheworld,behindtheU.S.andRussia.D.Nexttoelectricity,Canadianpaperexportscameto900millionUSdollarseveryyearinthe1960s.E.Twolargenuclearpowerplantsbegantogenerateelectricity.F.CanadaandtheU.S.importedandexportedpowerinalmostequalmeasuresafter1901.4.因果关系:如果空格前后出现表示因果关系的词或词组,空格与前后句子是因果关系Supposeyouhadanassistantwhoscreenedandselectedonlythequalitybooksforyou.____(1)____.Soyoucouldobtainaworkingknowledgeofthebook’scontentsinafractionofthetime.NowyoucanhavethatassistantwithExecutiveBookSummaries.A)Theseintroductorytextsarethemostimportantbooksandusingthemcanpaybigdividends.B)Discoverpracticaltipsandtechniquesyoucanapplywithoutdelay.C)Inordertoavoidthisproblem,weselectforyouonlythetrulyworthwhiletitlesandrejecttherest.D)Accordingtostudiespublishedinpsychologyjournals,youretainthecontentofasummarybetterthanabook.E)Heorshewouldtakethemostimportantideasfromeachone,andcompilethemintoaneatexecutivesummary.1.细节理解句出现在段落内部,考查的是段落内部句子之间,特别是前后句之间的逻辑关系。表示逻辑关系的标志词、连接词或插入语等。2.过渡句包括段落内部的过渡句和段落之间的过渡句。同义词、代词、上下义词、同一范畴词等。转折关系、并列关系、因果关系、递进关系。3.主题概括句以考查段落标题为主,设题位置一般在段首或段尾,考查文章的段落大意。有时也会考查整篇文章的标题句,即文章主旨句。文章主旨句往往以文章标题的形式出现。Passage1[2016·(全国Ⅰ)]Secretcodes(密码)keepmessagesprivate.Banks,companies,andgovernmentagenciesusesecretcodesindoingbusiness,especiallywheninformationissentbycomputer.Peoplehaveusedsecretcodesforthousandsofyears.36Codebreakingneverlags(落后)farbehindcodemaking.Thescienceofcreatingandreadingcodedmessagesiscalledcryptography.▶词汇详解①cryptographyn.密码学,为不可数名词。②spellout用字母拼,拼写;解释明白,讲清楚Couldyouspellthatnameoutagain?你能不能把那个名字再拼一次?YouknowwhatImean—I‘msureIdon‘tneedtospellitout.你明白我的意思,肯定不需要我解释了。Therearethreemaintypesofcryptography.37Forexample,thefirstlettersofMyelephanteatstoomanyeels“spelloutthehiddenmessageMeetme.38Youmightrepresenteachletterwithanumber,forexample.Let‘snumberthelettersofthealphabet,inorder,from1to26.Ifwesubstituteanumberforeachletter,themessageMeetmewouldread135520135.▶38空位于段首,所以可以根据设空位置选择答案。设空处在段首,通常为段落主题句,再阅读本段内容可得出答案。③substitutev.代替,取代。常见搭配:substituteAforB用A代替BsubstituteBwith/byA用A代替BAcodeusessymbolstoreplacewords,phrases,orsentences.Toreadthemessageofarealcode,youmusthaveacodebook.39Forexample,bridgemightstandformeetandoutmightstandforme.ThemessageBridgeoutwouldactuallymeanMeetme.40However,itisalsohardtokeepacodebooksecretforlong.Socodesmustbechangedfrequently.A.Itisveryhardtobreakacodewithoutthecodebook.B.Inanylanguage,somelettersareusedmorethanothers.C.Onlypeoplewhoknowthekeywordcanreadthemessage.D.Aslongastherehavebeencodes,peoplehavetriedtobreakthem.E.Youcanhideamessagebyhavingthefirstlettersofeachwordspellit
