kcountry，andhikerswouldespeciallyenjoyavacationthere．4使用连接副词连接。根据作者的意图和句子的需要。接排的句子可以使用连接副词来连接。这时，句子之间要用分号。在连接副词的后面还要加逗号，但是一般在单音节的连词后不加逗号。如so，yet。thus等.RevisedSentencesThegirlsscoredhigherinmath；however，theboysscoredhigherinverbalskills．Gesturesareameansofcommunicationforeveryone;neverthe1ess，theyareessentialforthehearing-impaired．Educationisanelusiveword;indeed,itoftenmeansdifferentthingstodifferentpeople．YellowstoneNationalParkconsistsoftwomillionacresofbackcountry;therefore,hikerswouldespeciallyenjoyavacationthere．5.使用从属连词、关系副词或关系代词连接.当可以判断出一个句子从逻辑上或意义上从属于另一个句子时,可以将此接排句改写成复合句。RevisedSentencesThegirlsscoredhigherinmath，whiletheboysscoredhigherinverbalskills．Althoughgesturesareameansofcommunicationforeveryone，theyareessentialforthehearing-impaired．Thepowerfailurecausedablackoutwhichcreatedalotofproblems．HikerswouldespeciallyenjoyavacationatYellowstoneNationalPark，whichconsistsoftwomillionacresofbackcountryDirections:Revisethefollowingrun-onsentencesWomennolongerneedtomoveintothetraditionallymaleprofessionstheyhavealreadyopenedmostofthedoorstodesirablecareerpaths．2．Icalledforareservationatafamousrestaurantintown，allthetablesweretakenbeforetheDragonBoatFestival．3．Ericwaslatetoworkheranalltheway．Revisedsentences1．Womennolongerneedtomoveintothetraditionallymaleprofessions，fortheyhavealreadyopenedmostofthedoorstodesirablecareerpaths．OR：Womennolongerneedtomoveintothetraditionallymaleprofessions；theyhavealreadyopenedmostofthedoorstodesirablecareerpaths．OR：Womennolongerneedtomoveintothetraditionallymaleprofessions．Theyhavealreadyopenedmostofthedoorstodesirablecareerpaths．OR：Becausewomenhavealreadyopenedmostofthedoorstodesirablecareerpaths，theynolongerneedtomoveintothetraditionallymaleprofessions．2．Icalledforareservationatafamousrestaurantintown．AllthetablesweretakenbeforetheDragonBoatFestival．OR：Icalledforareservationatafamousrestaurantintown，butallthetablesweretakenbeforetheDragonBoatFestival．OR：Icalledforareservationatafamousrestaurantintown；however，allthetablesweretakenbeforetheDragonBoatFestival．OR：Icalledforareservationatafamousrestaurantintown；allthetablesweretakenbeforetheDragonBoatFestival．OR：AlthoughIcalledforareservationatafamousrestaurantintown，allthetablesweretakenbeforetheDragonBoatFestival．3．Ericwaslatetowork，soheranalltheway．or：Ericranalltheway；otherwise，hecouldhavebeenlatetowork．or：BecauseEricwaslatetowork，heranalltheway．or：Ericranallthewaybecausehewaslatetowork．or：Ericwaslatetoworkalthoughheranalltheway．Directions:Identifyandcorrectseriouserrors(suchasfragments·fusedsentencesandcommasplices)ineachofthefollowing．1．Withouttellinganyone，evenhersister，Mary，goingtothepark，meetingherfriends．2．Thephysicsproblemswerejustimpossible，theytookalldaytodo·3．Thatthecoursewassohardweallstudieddayandnight,withnoonegettinganAoraB．4．Iknockedon／atthedoorwhentheladycameIgavehermostin-gratiatingsmile．5．Whydoyouaskwhatconcernisitofyours?6．Gettingmarriediseasy，stayingmarriedisadifferentmatter.7．Michelletriedeachoftheappetizersonthetable．Andthenfoundthat，whenthedinnerarrived，herappetitehadgone·8．Shedidn’tknowwhattosaytohisannouncement，shewasnotatacompletelossforwords，either．Revisedsentences1．Withouttellinganyone，notevenhersister，Marywenttotheparktomeetherfriends．2．Thephysicsproblemswerejustimpossible；therefore，theytookalldaytodo．3．Thecoursewassohardthatweallstudieddayandnight，withnoonegettinganAoraB．4．Iknockedon／atthedoor．Whentheladycame，Igavehermostingratiatingsmile．5．Whydoyouask?Whatconcernisitofyours?6．Gettingmarriediseasy；stayingmarriedisadifferentmatter．OR：Gettingmarriediseasy，butstayingmarriedisadifferentmatter．OR：Althoughgettingmarriediseasy，stayingmarriedisadifferentmatter．7．Michelletriedeachoftheappetizersonthetable．Shethenfoundthat，whenthedinnerarrived，herappetitehadgone．8．Shedidn’tknowwhattosaytohisannouncement，norwassheatacompletelossforwords，either.OR：Shewasneitherreadywitharesponsenoratacompletelossforwords．3.误置修饰语（MisplacedModifiers）在写作中，为了使句子生动和更具有吸引力，常常需要添加修饰语。按照英语构句规则，充当定语或状语的词、短语或从句必须尽可能地靠近所修饰的成分。如果忽视了这个规则，在修饰语和其所修饰的中心词之间不恰当地夹进了其他成分，就可能造成句子意思混淆，产生歧义。请看下面句子：MisplacedModifiersHesoldtheoldcartothemanwithleatherseats．Pleasegivethebooktotheboywiththebluecover．Thatcatbelongstomyneighborwithfivekittens．RevisedSentencesHesoldtheoldcarwithleatherseatstotheman．Pleasegivethebookwiththebluecovertotheboy．Thatcatwithfivekittensbelongstomyneighbor．如果一个修饰语既可以修饰其前面的词也可修饰其后面的词，这样的修饰语称为歧义修饰语(squintingmodifier)。歧义修饰语会使读者对其修饰目的感到困惑不解。所以，应该把易产生歧义的修饰语放在它所惟一修饰的词的前面。例如：Theequipmentwithouttheaccessoriessoldthebest．(Differ-enttypesofequipmentwereavailable，somewithandsomewithouttheaccessories．)Theequipmentsoldthebestwithouttheaccessories．(Onetypeofequipmentwasavailable，andtheaccessorieswereoptional．)SquintingModifiersWeagreedonthenextdaytomaketheadjustments·Studentswhopracticewritingoftenwillbenefit．RevisedSentencesWeagreedtomaketheadjustmentsonthenextday·(Weagreedthatonthenextdaywewouldmaketheadjustments)-OrOnthenextday，weagreedtomaketheadjustments．(Onthenextday，weagreedthatwewouldmaketheadjust-ments．)Studentswhooftenpracticewritingwillbenefit．Studentswhopracticewritingwilloftenbenefit．所以，在写作中我们要特别注意副词的位置，要把它们放在使读者对句子的意义更清楚的地方。请分析下面这个句子：Heonlysuggestedthreerulesforustofollow．除非我们在这里确实是指“Heonlysuggestedthem；hedidn’tinsistonthem．”，否则only这个词就应放在它所修饰的词前面：HesuggestedonlythreerulesforUStofollow．要注意句子会随着only位置的改变而改变其意义。Directions：Identifythemisplacedwordorwordsineachsentence．Thenrewritethesentencesandmakethemeaningclear．1．Ourteamdidn’tevenscoreonce．2.SheisteachingaseminarthistermonmarketeconomyattheOsakaInternationalUniversity.3．Thecityalmostspenttwentymilliondollarsonthenewstadium4．Tonyboughtanoldcarfromacrookeddealerwithafaultytransmission．5．Thesuburbsnearlyhadfiveinchesofrain．6．Wecouldseethefootballstadiumdrivingacrossthebridge．7．IalmosthadadozenjobinterviewsafterIsentoutmyresume8．TherewerestrongcallsforanimmediateceasefireintheUNSecurityCouncil9.Theexchangestudentswemetforcoffeeoccasionallyquestionedusaboutourlatestslang.10.IputthechairinthemiddleoftheroomthatIhadrecentlypurchased.Revisedsentences1．Ourteamdidn’tscoreevenonce.2．ThistermsheisteachingaseminaronmarketeconomyattheOsakaInternationalUniversity．3．Thecityspentalmosttwentymilliondollarsonthenewstadium．4．Tonyboughtanoldcarwithafaultytransmissionfromacrookeddealer．5．Thesuburbshadnearlyfiveinchesofrain.6．Drivingacrossthebridge，wecouldseethefootballstadium.7．IhadalmostadozenjobinterviewsafterIsentoutmyresume.8．TherewerestrongcallsintheUNSecurityCouncilforanimmediateceasefire．9．Theexchangestudentsweoccasionallymetforcoffeequestionedusaboutourlatestslang．OR：Theexchangestudentswemetforcoffeequestionedusoccasionallyaboutourlatestslang.1O．IputthechairthatIhadrecentlypurchasedinthemiddleoftheroom．4．悬垂修饰语(DanglingModifiers)悬垂修饰语是与句子的主语不能构成逻辑关系的修饰语。悬垂修饰语可以出现在句中的任意位置，但大多位于句首。请看下面例句：DanglingModifiersBygoingtothevarioussororityhousesoncampusandmeetinghundredsofnewgirls，myconversation，manners，andpoisebecamemorepolished．Towritetheproposal，researchmustbedone．两句中斜体的修饰语与句子的主语不存在逻辑关系。在第一句中，当作者想当然地认为“I”是句子的主语，并打算对自己做个描述。但是由于用了“myconversation…”做句子的主语就破坏了句子中的逻辑关系而引起荒谬可笑的解释：Itwasherconversationthatvisitedthesororityhouses．动词的非限定性短语作状语时，其逻辑主语必须与句子主语保持一致，否则就会形成悬垂性修饰语。如果把句子的主语改成“I”，就可改成一个令人满意的句子了。同样，在第二句中，动词不定式在逻辑上不能修饰句子的主语，theresearch．RevisedSentencesBygoingtothevarioussororityhousesoncampusandmeetinghundredsofnewgirls，Ipolishedmyconversation，manners，andpoise．Towritetheproposal,theprofessormustfirstdosomere-search．2．悬垂动名词(DanglingGerund)DanglingModifiersByinstallingabirdbath．thebirdsweregivenasourceofwater．Afterfinishingtheresearch，thepaperwaseasytowrite．RevisedSentencesByinstallingabirdbath，wegavethebirdsasourceofwater．Afterfinishingtheresearch，Ifoundthatthepaperwaseasytowrite．3．悬垂动词不定式(DanglingInfinitive)DanglingModifiersToskiproperly，acourseofinstructionisnecessary．Towritewell，goodbooksmustberead．RevisedSentencesToskiproperly，abeginnershouldtakeacourseofinstruction.Towritewell,Imustreadgoodbooks.．4．悬垂省略从句(DanglingEllipticalClause)DanglingModifierWhileclimbingthehill，therainbegantofall·Whenonlyasmallboy，myfathertookmewithhimtoChicago·RevisedSentencesWhileclimbingthehill，shefelttherainbeginningtofall·WhenIwasonlyasmallboy，myfathertookmewithhimtoChicago．常用的修改悬垂性修饰语的方法有：1.找出句子中隐含的主语，对所修饰的短语提供行为者(actor)(承担动作行为的人或物).DanglingModifiersAttheageofsixmyuncleboughtmyfirstpet，agoldfish.Whileleavingthehouse，thephonerang·Usingthisdrug，manyundesirablesideeffectsareexperienced．RevisedSentencesAttheageofsix,Ireceivedmyfirstpet,agoldfishfrommyuncle．Whileleavingthehouse,Iheardthephonering·Usingthisdrug，patientsexperiencemanyundesirablesideeffects．2.补足悬垂短语或省略从句必要的成分，扩展其成为一个完整的从句，由行为者做主语.RevisedSentencesWhenIwassix，myuncleboughtmemyfirstpet，agoldfish·AsIwasleavingthehouse，thephonerang.Manyundesirablesideeffectsareexperiencedwhenthisdrugisused.Directions：Pleaserevisethefollowingsentenceswithdanglingmodifiers．1．Thumbingthroughthemagazine，hereyesautomaticallynoticedthecosmeticads．2．Topleasethevisitors，acrosstalkwasperformed．3．Onenteringtheteacher’soffice，aterrestrialglobecaughthisattention．；4．Thoughonlyseventeen，thearmyacceptedhisapplication．5．Fromattendingprofessionalmeetings，importantlessonscanbelearned．6．Withfiftypageslefttoread，WarandPeacewasabsorbing．7．Onthenewsstandsonlyanhour,itssalessurprisedeveryone．8．Whileeatinglunchinthecafeteria，thecomputermalfunctionedRevisedsentences1．Hereyesautomaticallynoticedthecosmeticadsasshewasthumbingthroughthemagazine．2．Topleasethevisitors，theyperformedacrosstalk。3.Onenteringtheteacher’soffice，henoticedaterrestrialglobe．4.Thoughhewasonlyseventeen，thearmyacceptedhisapplication.5.Fromattendingprofessionalmeetings，welearnedsomeimportantlessons．6.Withfiftypageslefttoread,TinafoundWarandPeacewasabsorbing.7.Becausethemagazinehadbeenonthenewsstandsonlyanhour,itssalessurprisedeveryone．8.Whiletheprogrammerwaseatinglunchinthecafeteria，thecomputermalfunctioned．Directions：Herearesentenceswithdanglingmodifiers．Correctthemintwoways．Eitherplacethesubjectwithintheopeningwordgroup，orplaceitrightaftertheopeningwordgroup．1.Swimmingatthelake，arockcutMaria’sfoot．2.Whileeatingmysandwich，fivemosquitoesbitme．3.G
