Unit3Lookinggood,feelinggood,Non-restrictiveattributiveclauses,Grammarandusage,1.定语从句(attributiveclauses)通常由关系代词或关系副词引出。常见的关系代词有：which(指物)，that(既可指人又可指物)，who(指人，在定语从句中作主语或宾语)，whom(指人，在定语从句中作宾语)，whose(指人或物，作定语)等。关系副词有:when(指时间)，where(指地点)，why(指原因)等。,2.定语从句分为限制性定语从句(restrictive)和非限制性定语从句(non-restrictive)两种。限制性定语从句紧跟先行词，与先行词之间一般不加逗号；非限制性定语从句与主句之间通常用逗号分开。,FindoutsomesentenceswithNon-restrictiveattributiveclausesinourtextDyingtobethin,1.Mymother,whoyoumetlastyear,keepstellingmenottotakethembecausetheyaredangerous.2.Imtakingweight-losspillscalledFat-Less,whicharequitepopularamongyoungwomenhere.,Non-restrictiveattributiveclauses:,3.Mymotherinsistedonsendingmetothehospital,whereIreceivedgoodmedicaltreatment.4.ItsthesameinChinamanypeople,someofwhomarenotoverweightatall,arealwaysgoingondietortakingweight-losspills,whichareoftendangerous.,Differencesbetweentherestrictiveandnon-restrictiveattributiveclauses.,Discussion,Lookatthefollowingexamplesandtellthedifferencesbetweenthesentences.,1.Ihaveasisterwho/thatworksinahospital.我有一位在医院工作的姐姐。2.Ihaveasister,whoworksinahospital.我有一位姐姐，她在医院工作。,Example2,不只一位姐姐,只有一位姐姐,Conclusion2,1.限制性定语从句与先行词关系密切，是先行词不可缺少的部分，如果去掉它，主句意思往往不明确。2.非限制性定语从句是对先行词的补充或说明，去掉它也不会影响主句的意思。,1.Hisfather,whoworksinBeijing,camebackyesterday.2.Shanghai,whichisinEastChina,isdevelopingrapidly.,Example1,Conclusion1,当先行词是地名、人名、世界上独一无二的事物或家庭唯一成员时，通常只用非限制性定语从句修饰。,Thisisthehouse(which/that)weboughtlastmonth.这是我们上个月买的那幢房子。2.Thehouse,whichweboughtlastmonth,isverynice.这房子很漂亮，是我们上个月买的。,Example3,限制性定语从句,非限制性定语从句,3.HeseemsnottohavegraspedwhatImeant,whichgreatlyupsetsme.他似乎没领会我的意思，这使我心烦。,非限制性定语从句,Conclusion3,1.限制性定语从句可以由关系代词，关系副词来引导，关系代词作宾语时可以省略。2.非限制性定语从句既可修饰先行词，又可修饰整个主句，不可用that引导且关系代词不可以省略。,1.Thefamousbasketballstar,_comesfromAmerica,willvisitourschoolsoon.2.Inthosedays,sheusedtogotoMrblack,with_shehadawonderfultime.3.Iboughtacaryesterday,_costmealot.,which,whom,who,4.Xian,_Ivisitedlastyear,isaniceoldcity.5.HewillcometoseemenextJuly,_hewontbesobusy.6.Theschool,_Ioncestudied,wasbuiltthirtyyearsago.,which,where,when,7.Johnsaidhedbeenworkingintheofficeforanhour,_wastrue.8._weallknow,heisgoodatEnglish.,As,which,II.all/some/of+whom/which引导非限制性定语从句,Example:,Hehastoldusmanystories,allofwhichareaboutthefamousLongMatch.2.ThestudentsofClass1,someofwhomcamefromJapan,wentcampingyesterday.,Conclusion,在非限制性定语从句中，一些表达数量或定位的数词或代词如all/some/one/both/neither/none/any/either/any等可与of构成介词词组修饰限制先行词，此时先行词在其后的定语从句中作介词的宾语，关系代词不可用that。如先行词指人则用whom，如先行词指物则用which引导从句。,1.Manystudentsinthisschool,someofwhicharenotoverweight,aregoingondiets.2.Thereare54studentsinmyclassandtenofwhomcomefromUS.,whom,Correction:,them,3.Halfamillionpairsofshoesareproducedbytheworkershereeveryyear,80%ofwhomaresoldabroad.4.Ihavemanyfriendsinthistown,someofwhicharebusinessman.5.Iamdoingdifferenttypesofexercises,allofthemarequitehelpfultomyhealth.,which,which或all前加and,whom,非限制性定语从句考点归纳：,as和which引导非限制性定语从句，代替整个主句。,1.Aseveryoneknows,Chinaisacountrywithalonghistory.众所周知，中国是一个历史悠久的国家。,Example:,2.Sheisateacher,asisclearfromhermanner.她是个教师，这一点从她的举止可以清楚地看出。3.Hemissedtheshow,whichwasreallyagreatpity.他错过了演出，这真是很大的遗憾。,Conclusion,1.as和which在引导非限制性定语从句时，as和which可代替整个主句，相当于andthis或andthat。这两个关系代词都可指代主句所表达的整个意思,且在定语从句中都可以作主语和宾语。,2.as和which引导非限制性定语从句的不同之处在于：(1)as引导的定语从句可置于句首，而which引导的定语从句不可放在句首。(2)as代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若从句中的谓语为行为动词，则从句中的关系代词只能用which。另外，as引导非限制性从句，常带有“正如”的意思。,Alicereceivedaninvitationfromherboss,_cameasasurprise.2.Theweatherturnedouttobeverygood,_wasmorethanwecouldexpect.3._isexpected,theEnglandteamwonthefootballmatch.,As,which,which,4.Itrainedhardyesterday,_preventedmefromgoingtothepark.5._wecansee,thesmokecamefromthelittledustbin.,which,As,Helenwasmuchkindertoheryoungestsonthantotheothers,_,ofcourse,madetheothersenvyhim.A.whoB.thatC.whatD.which,Practicetime,2.TheEnglishplay,_mystudentsactedattheNewYearsparty,wasagreatsuccess.A.forwhichB.atwhichC.inwhichD.onwhich,3.Thereweredirtymarksonhertrousers_shehadwipedherhands.A.whereB.whichC.whenD.that4.Greatchangeshavetakenplaceinthatschool.Itisnolongerwhatitwas20yearsago,_itwassopoorlyequipped.A.whenB.whichC.whatD.that,5.TheBritisharenotsofamiliarwithdifferentculturesandotherwaysofdoingthings,_isoftenthecaseinothercountries.A.itB.thatC.asD.so,Joineachpairofsentencestofromonesentence,usingoneofthemasanon-restrictiveattributiveclausewithwho,whom,whose,which,whereorwhen.Amyisanactress.SheisZhouLingsfriend._,Amy,whoisZhouLingsfriend,isanactress.,2.ThedoctorsatthehospitaltriedtheirbesttosaveAmy.Amyspendabouttwomonthsinthathospital._3.Amyeatslotsoffruitandvegetables.Allofthemaregoodforherhealth.,Thedoctorsatthehospital,whereAmyspentabouttwomonths,triedtheirbesttosaveAmy.,_4.Amysometimesgoesforawalkintheafternoon.Itisfineandwarmintheafternoon._,Amyeatslotsoffruitandvegetables,allofwhicharegoodforherhealth.,Amysometimesgoesforawalkintheafternoon,whenitisfineandwarm.,5.MyuncleisanengineerandisworkinginBeijing.Itoldyouabouthimyesterday._6.MikehasdecidedtovisittheG
