However,thiswritingprocessconstitutesanirksomeandproblematicactivityinstudents’learningEnglish.DuringtheprocessofEnglishteaching,wefindoutthecausesoflearners’writingproblems.Amongthem,twomajoronesarepresentedasfollows:thediscontinuityofcohesionandthediscontinuityofcoherence.Itissuggestedthattwofactorsaremainlyresponsibleforthesetwodiscontinuities.Oneis“alternativeusesofdifferentregisters”andtheotherisan“indirectapproach”usedbylearnerstodeveloptheirtopics.Bothofthemcausetheflowofdiscoursetostopanddeviatefromtopics,whichresultsintheforementioneddiscontinuitiesofcohesionandcoherence.ThemainpurposeofwritingthispaperishowtoapplythetheoryofcoherenceandhowtodirectourstudentsinEnglishwriting.
2.Cohesionandcoherenceinwritingatext
Cohesionandcoherenceinwritingatextprovidethemeansforbothwriterandreadertocommunicate.So,writingatextwellhastobebothcohesiveandcoherent.
(1)Cohesioninwritingatext
Toachievetheobjectiveofconveyingthewriters’meaning,thewriterhastoavoiddistractingthereaderfromhismessagebymakingitunderstood,whichistoensurecontinuitybetweenonepartofthetextandanother.Thebestwayofachievingthisistousecohesionappropriatelysothatitholdssegmentsofatexttogether,makingitasemanticedifice,justasmortardoesbricksorstoneinabuilding.Seethefollowingpassage.
AlittleboycalledMikewentintothewoodsfarawayfromhisvillageoneday.MikewasverypleasedtoseelovelysmallanimalsApplicationEnglishwritingandbirds.Hewassobusywatchingthiswonderfulworldthathedidn’tnoticeanuglywolfapproachinghim.Theboywastoolatetobeawareofthedangerandthewolfswallowedhim.
Fromtheabovepassage,wecanseethatastypicalchainoflexisandreference——“AboycalledMike.Mike.He.Theboy.him.”——runsthroughthewholepassage,andholdsinpidualclausestogetherandmakesthewholestoryreadable.Thechainoflexisandreferenceisoneoffourmainchainsthatservethesamefunctionofholdingthetexttogether.Theotherthreearethechainsofellipsis,ofsubstitution,andofconjunction[2].
Theaboveexampleshows,cohesionpavesthewayforcoherenceandbothworktogethertofacilitateinterpretationofthetexti.e.,itis“cohesivechains”thatmainlyprovidecoherenceinwritingatext.
(2)Coherenceinwritingatext
“Alllanguageneedsameanoflinkingoneparttoanotherinatext”[3],orinotherwords,writersneedtokeepthemessagesequenceclear.Thisisoftenreferredtoascoherence.Coherenceisachievedthroughtwoaspects:Semanticandcohesivechains.e.g.
AlfredNobel,theSwedishinventorandindustrialist,wasamanofcontrasts.Hewasthesonofabankrupt,butbecameamillionaire;ascientistwithasloveofliterature,anindustrialistwhomanagedtoremainanidealist.Hemadeafortunebutlivedasimplelife,andalthoughcheerfulincompanyhewasoftensadinprivate.Hewasagreatfigurewithaconflictingcharacter[4].
Therearetwocohesivechainsinthispassage.Thefirstoneis:“AlfredNobel.He.He.He.”Thesecondoneis:“amanofcontrasts.thesonofabankruptbutbecameamillionaire.madeafortunebutlivedasimplelife.cheerfulincompanybutsadinprivate.”
3.Howtoapplythetheoryofcoherenceinwritingacoherenttext
Therearetwomainmethodsofachievingcoherenceintextwriting:touselogicalorderproperlyandtouselinkingdevicescorrectly.
(1)Logicalorderinformingatext
Thelogicalorderofpassagesorevenawholetextisusuallyarrangedinthefollowingmodes.

(2)Linkingdevices
Besidesthelogicalordermentionedabove,touselinkingdevicescorrectlyisaneffectivewaytoachievingcoherenceinwritingatext.Linkingdevicesincludeusingpronoun,transitionalwordsandexpressions,usingkeywordandrelatedsentencepatternrepeatedly.
4.Howtodirectstudentsinwritingatext
“Textisasemanticunit:aunitnotofformbutofmeaning”[1].
Sinceitisasemanticunit,atexthassemanticstructure.Thissemanticunit,atexthassemanticstructure.Thissemanticstructureissupportedbymeansofcohesion.Withoutcohesion,therewouldbenocoherencewithinatextandthenthetextwouldnotbeatext.Inordertodirectstudentsinwritingatext,weshouldfindoutwheretheproblemsareinstudents’passagewriting.Thefollowingaretwoexamples.
Example1:Hereisacartoonconcerningpraise.Thepictureshowsahusbandwhoisquiteindifferenttoherwife’swinningmedalandhowdisappointedhiswifeis.Itreflectspeopleareoftenreluctanttogivepraisewhileweareeagertogetit.Inthepicture,thehusbandevendidnotraisehiseyesfromanewspaper.
Example2:Honestyisaveryimportantpartofone’scharacter.Thischaracterwillaffectyouwhenyougrowup.Ifyouareanhonestman,peoplecanbelieveinyou.Whenyouareindifficulty,theywillhelpyou.Andwhenyoumeetsomethingwhichyoucan’tdo,peoplearegladtohelpyou,Ifyouarehonest,peoplewilltrustyouandtheywillmakefriendswithyou.Inaword,honestisagoodcharacter.Itcanbringyouhappiness.
FromExample1,wecanseethatthepassageseemslikeatextbuthasnosemanticconnectionsbetweenonepartofthetextandanother——thefirstsentenceisadescriptionofthepicture.Thencomesasentenceofinterpretation.Anothersentenceofdescriptionfollows,andsoonandon.
Example2showsthatoncethetopicsentence.“Honestyisanimportantpartofone’scharacter”isfont,thetheme“Honesty”,shouldgovernthediscoursethatfollows.Itisamajortarget,presupposedbythewholetext.Unfortunately,thelearnerdidn’tchoosetheproperthemefromthetopicsentenceasthethemeforthenextclauseandsocontinuethedecidedtopic.Insteadheevadedthetopicandusedawrongtheme,“you”,whichwasirrelevant.Thus,theprocessofformingcohesivechainswasbroken,thesemanticmovementstoppedandnosemanticrelationshipbetweenclauseswasestablished.
Asforcoherence,semanticconnectionswerenon-existentasthetopic,honesty,hadthepartfollowingtalkingaboutwhatyoushouldbelikeasaperson.Byindirectapproach,thelearnerintroducedotherthemesbyusingsuppositions,examplesandremindersthatwereirrelevantagain.Itwasthesethatbrokethecohesivechainsofthetextandbroughtaboutthediscontinuityofbothcohesionandcoherence.
Fromtheaboveexamples,wecanseethatourstudentsusuallydeveloptheirtopicsbyalternativeusesofdifferentregisters(example1)andanindirectapproach(example2),whichresultinthediscontinuityofbothcohesionandcoherence.Hence,Gameofcohesionandcoherenceforbothwriterandreadertoabidebyhasbeenviolated.Towriteacoherenttext,thisviolationhastobecorrected.IthasbeensuggestedthatmanywaysareprovedvaluabletoachievingcoherenceinEnglishwriting.Theyare:①enrichthestudents’backgroundknowledge.②analyzethestructureofthetextforthestudents.③raisethestudents’awarenessoflearningtowrite.④comparevariousstylesofwriting.Byusingthesemethods,learnersarecompelledtoconsciouslyrecognizetheproblemsinvolvedindiscoursewriting,which,inturn,mayhelpthembecomeawareofwhatisneededtowritegoodcompositions.
5.Conclusion
The“alternativeusesofdifferentregisters”and“indirectapproach”arenotEnglishwaysofwriting.Englishlearnersshouldestablishpropercohesivechainsonwhichthecoherenceisbased.TherearemanywaystoachievingcoherenceinEnglishwriting.Besidesthemethodsmentionedabove,touselogicalorderandlinkingdevicesproperlyarealsogoodwaystowriteacoherenttext.
