Sentencepattern•英语句式可分为三类：简单句(Simplesentence)，并列句(Compoundsentence)和复合句(Complexsentence)•当一个句子只包含一个主谓结构时称为简单句。•含有两个或两个以上独立分句的句子叫并列句，这些独立分句处于平等的、互不依从的并列地位。•复合句是一个主句和一个或一个以上的从句构成。主句是全句的主体，通常可以独立存在；从句则是一个句子成分，不能独立存在。但是从句也有主语和谓语部分。所不同在于，从句须由一个关联词引导，起到联系从句和主句的作用。Whichsentencepatternisit?•Shewasanauthorandshewrotethisgreatbook.•Shewasanauthor.Shewrotethisgreatbook.•Shewastheauthorwhowrotethisgreatbook.并列句简单句复合句Howtodistinguishanattributiveclause?Shewasthepersonwhowrotethisgreatbook.先行词关系词主句定语从句在主从复合句中起定语作用，修饰句中的名词或代词的从句称为定语从句，被修饰的名词或代词称为先行词(theantecedent)。引导定语从句的词叫关系词(theguideword)。Step1：找谓语动词•Myambitionistoworkforafirmthatdevelopscomputersoftware.Step2:判断句式•判断句子是简单句(只有一个主谓结构)，并列句(由并列连词and,but,or等连接)还是复合句(由从属连词引导)•Myambitionistoworkforafirmthatdevelopscomputersoftware.复合句thatStep3：找从句及主句•从句也有主语和谓语部分，从句须由一个关联词引导，起到联系从句和主句的作用。•关联词之后的主谓结构与关联词构成从句。•Myambitionistoworkforafirmthatdevelopscomputersoftware.从句thatdevelopscomputersoftwareStep4：判断从句类型•根据从句在句子中充当的成分来判断从句类型。•Myambitionistoworkforafirmthatdevelopscomputersoftware.名词充当先行词thatdevelopscomputersoftware定语从句•ProfessorSmithwhohasreturnedfromHarvardUniversitywillgivealectureonBritishliteratureinthelecturehalltomorrow.•ThisisthebiggestchangethatIhaveexperiencedsofar.•Thenovelthatyoulentmelastweekisreallyinterestingandtouching.whofromHarvardUniversitywhohasreturnedthatthatIhaveexperiencedsofarthatthatyoulentmelastweek1.Thebreakthroughcameafter40yearsofresearchbyProfessorGeoffRaisman,whofoundthatcellshadthepossibilitytorepairdamagetonasal(鼻腔的)nerves,theonlypartofthenervoussystemthatconstantlyre-grows.2.“Theideawastotakesomethingfromanareawherethenervoussystemcanrepairitself,anddoessothroughoutlife,andputitintoanareathatdoesn’trepairitself,”,ProfessorRaismansaid.•Thebreakthroughcameafter40yearsofresearchbyProfessorGeoffRaisman,whofoundthatcellshadthepossibilitytorepairdamagetonasal(鼻腔的)nerves,theonlypartofthenervoussystemthatconstantlyre-grows.whofoundthatcellshadthepossibilitytorepairdamagetonasal(鼻腔的)nervesthatconstantlyre-grows非限定性定语从句，关系词在从句中作主语限定性定语从句，关系词在从句中作主语•“Theideawastotakesomethingfromanareawherethenervoussystemcanrepairitself,anddoessothroughoutlife,andputitintoanareathatdoesn’trepairitself,”,ProfessorRaismansaid.wherethenervoussystemcanrepairitselfthatdoesn’trepairitself限定性定语从句，关系词在从句中作状语限定性定语从句，关系词在从句中作主语定语从句的考察考察形式•阅读中长难句分析•语法填空•短文改错•书面表达考点•从句判断•关系词•主谓一致判断方法关系词关系词只用which关系词只用who关系词只用that关系副词在从句中作状语判断方法关系词关系代词关系副词关系词只用which关系词只用who关系词只用that关系副词在从句中作状语找从句(缺成分)，前有名词或代词which,that,who,whom,as,whosewhen,where,whywhywherewhen先行词为时间名词，表时间先行词为reason，表原因先行词为(抽象化)地点名词，表地点theonly,thevery;thesame,no,any;两项并列人与物;不定、序数、最高级在非限定性定语从句中先行词“非人”;当从句中谓语动词短语中的介词提前时先行词是one,ones,anyone,those等时;在非限定性定语从句中，先行词指人时IjustreadabookcalledTechnoStress,1.___waswrittenbyDr.MichelleM.Weil.Herco-authorwasDr.LarryD.Rosen,2.___isherhusbandandalsoapsychologist.Accordingtotheauthors,everybodyfeelsstressedabouttechnology.Ourcellphones,3.___webuyforemergencies,sooninvadeourprivacy.Justbecausetheycan,peoplecontactusatplaceswherewearerelaxing.Anotherproblem4.___wearefacingis5.___wehavetolearntoomuchtoofast.Technologicalchanges,6.___usedtocomeoneatatime,nowoverwhelm(淹没)us.Dr.Weilsuggests7.__wereadherlatestbook,8.___wecanturnindealingwithtechnostress.Itcanbepurchasedfromherwebsite.Groupwork•统一答案•找出定语从句（从句类型，先行词，关系词所充当的句子成分）•IjustreadabookcalledTechnoStress,1._______waswrittenbyDr.MichelleM.Weil.Herco-authorwasDr.LarryD.Rosen,2.______isherhusbandandalsoapsychologist.Accordingtotheauthors,everybodyfeelsstressedabouttechnology.Ourcellphones,3._______webuyforemergencies,sooninvadeourprivacy.whowhichwhich•Justbecausetheycan,peoplecontactusatplaceswherewearerelaxing.Anotherproblem4.____________wearefacingis5.______wehavetolearntoomuchtoofast.Technologicalchanges,6.________usedtocomeoneatatime,nowoverwhelm(淹没)us.Dr.Weilsuggests7._____wereadherlatestbook,8._________wecanturnindealingwithtechnostress.Itcanbepurchasedfromherwebsite.that/whichthatwhichthattowhichTakeacardfromtheteacher.Workingroupsanddescribetheobjectorthepersononyourcardbyusingattributiveclausewithin2minutes.Shareyourworkwithyourclassmatesandguesswhoorwhatitis.1.Thisisthefactorywherewevisitedlastweek.2.ThepersontowhoyouspokeisastudentofGradeTwo.3.Thesungivesofflightandwarmth,thatmakesitpossibleforplantstogrow.4.I’vereadallthebookswhichIborrowedfromthelibrary.which/that或者删掉where先行词作宾语whom,关系词前有介词which,非限制性定语从句that，先行词有不定代词all修饰5.ThisisthebestfilmwhichIhaveeverseen.6.MyfatherandMr.Smithtalkedaboutthingsandpersonswhotheyrememberedinthecountry.7.Everythingwhichwesawwasofgreatinterest.8.Theyworkinafactorythatmakeradioparts.that,先行词由最高级修饰that,先行词有人也有物that,先行词是不定代词makes,先行词(第三人称单数)在从句中作主语Tellwhetherthefollowingsentencesincludeattributiveclauseornot.Ifyes,markit.1.Laterthatafternoon,anotherbigquakewhichwasalmostasstrongasthefirstoneshookTangshan.2.Thearmyorganizedteamstodigoutthosewhoweretrappedandtoburythedead.whichwasalmostasstrongasthefirstoneshookwhoweretrapped3.Iknowyouaredyingtoknowmylifehere,soI’veincludedsomephotoswhichwillhelpyoupicturetheplaces
