ygives“notonly”连接两个相等的成份，用第三人称单数。,Iamhappywithanyprogrambuttheothersspentalotoftimearguingwas此句描述的是过去的事情，且下句也是用的过去时，故要改为was。Irememberedherwordsandcalmdown.calmed连词and连接两个相等的成份。,c.指代一致,1)TheSmithsdidhisbesttomakemefeelTheirtheSmiths指代一家人或夫妇俩。2)Andtheymustnotbreaktherulestoooftenifwewanttowinthegames.谈论都是“我们”的事，此处也应一致。,3)Somewantedtoseetheprogramwhileotherspreferredanother.Theone表示三者以上的代词搭配oneanother,d.修辞一致：平行结构,平行结构中并列、对等部分应在形式上或意义上保持一致而实际上却未能如此。BlackSmithmoppedthefloor，cleanedthewindows，andotheroddjobsAnd(did)other该句谓语应由三个不同并列动作构成。,ThevalueofacoursedependsasmuchonitsinherentinterestonitspracticaluseInterest(as)on本句中asmuchas结构表示并列比较。,13逻辑关系,连词或连接性副词,连词或连接性副词常用来明示句子间的逻辑关系，错误使用往往造成逻辑关系的混乱。在改错中，这类错误比较隐蔽，难度较大，因为它涉及的上下文往往不仅仅是一个句子，而是前后几个句子甚至是全篇解题时，首先要掌握连词的意义和用法，二是要弄清上下文意思，理顺文章的逻辑，三是要注意连词的搭配使用。,In1860,becausesomeofthefarmpopulationhadmovedtothecity,yeteightypercentoftheAmericanpopulationwasstillinthecountry.Becausethough/althoughMusicisplayedineverysupermarket,itappearsthatweallfindcompanyinsound,ifwealldemandalittlequietfromtimetotime.Ifbut/though/although,Underthispressuretheirwholewayoflife,eveniftheirbodies,becameradicallychanged.Theybecamechasers,runners,jumpers,aimers,throwersandpreykillers.evenifeven,反义词,通过反义词来瞒天过海，也是这类题的一个惯用伎俩。Shewassmilingbutnoddingatme.and微笑和点头意义一致Myroommateisgenerous，inconsiderate，andeasytogetalongwithinconsiderate为considerate根据上下文的意思应为“体谅人的”之意。,Getsomeonetocheckforspellingandgrammaticalerrors,becauseaspell-checker（拼写检查程序）willpickupeverymistake.willwillnot,Thereisenoughaudienceandalsoitisalargeroom，youwillprobablynothavetouseamicrophone去掉notScienceitselfisharmless，butassoonasitcanprovidetechnology，itisnotnecessarilyharmfulharmfulharmless本句说明科学有时具有危害性,TheDepartmentofEnvironmentthatwascreatedshowshowunimportantthisissueisconsideredtobeUnimportantimportant上下文所要说明的是该问题的重要性。His(thefootballers)killingweaponhasturnedintoaharmlessfootballandhispreyintoagoalmouth.Ifhisaimisinaccurateandhescoresagoal,heenjoysthehunterstriumphofkillingprey（猎物）.Inaccurateaccurate,介词或动词短语,Earlyaudits（审查）showedthatminoritieswerepicturedfartooinfrequentlyandwerepicturedwithadisproportionatenumberofnegativearticles.Theauditresultfromimprovementinthefrequencyofminoritiesrepresentationandtheirportrayalinneutralorpositivesituations.And,witharesult,theSeattleTimeshasimprovedasanewspaper.ResultfromresultinWitharesultasaresult,Practice1,Thismayseemanoddquestionafterseveralsuccessiveyearsinwhichthedollarsspentonlineadvertisinghaveshownextraordinaryleaps.Buttherearetworeasonsforaskingit.Oneisthatbusinessesdepend_1ononlineadvertisinghasbeendisproportionatelyhurtby_2thedownturninthepublicmarkets.,Theotheristhatalittleauthoritativecommentatorsbelievetheonlineadvertisingmodelis_3fundamentalybrokenandadvisingcompaniesare_4de
