Period5GrammarTheAttributiveClause（non-restrictive)1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。2．先行词：被定语从句修饰的词叫先行词。3．关系词：引导定语从句的词叫关系词。关系词有关系代词和关系副词。关系代词有thatwhichwhowhomwhoseas等；关系副词有whenwherewhy等。关系词通常有下列三个作用：A、引导定语从句；B、代替先行词；C、在定语从句中担当一个成分。限制性定语从句(restrictive)非限制性定语从句(non-restrictive）TheteachertoldmethatTomwastheonlypersonthatIcoulddependon.老师告诉我说汤姆是我唯一的可以依靠的人。Hismotherwholoveshimverymuchisstrictwithhim.他妈妈十分地爱他对他要求很严格。1.限制性定语从句和非限制性定语从句:限制性定语从句:所谓限制性定语从句就是先行词在意义上不可缺少的定语如果去掉主句就会失去意义或意义不完整。这种从句和先行词的关系十分密切写时不用逗号和主句分开。非限制性定语从句:非限制性定语从句和主句的关系并不十分密切只是对先行词做些附加说明如果去掉主句的意思仍然清楚。这种从句和主句之间往往用逗号隔开。在讲话时语调上须停顿。一般不用that引导。2)YesterdayImetLiLeiwhoseemedtobeverybusy.昨天我碰上李雷了他好象很忙。(去掉从句意义仍然完整:昨天我碰上李雷了。)b.指人时主格用who宾格用whom物主格用whose(也可指物)。MissHowewhomyoumetinthelibraryisournewteacher.2)TheArabswhoarefamousfortheirhorsesandcamelsusetheseanimalsforworkandinsports.3)LiMingwhosemotherhasbeenillfortwodaysisabsentfromschooltoday.c.另外关系副词when(指时间)where(指地点)也可以引导非限制性定语从句(注意关系副词why不能引导非限制性定语从句);why不引导定语从句。d.介词加关系代词也可以引导非限定性定语从句。3.aswhich非限定性定语从句由aswhich引导的非限定性定语从句as和which可代整个主句相当于andthis或andthat。As一般放在句首which在句中。限制性定语从句和非限制性定语从句的区别Testhowwellyoumasterit?YesterdayMr.Lifinallyboughthisownhouse_______isahospital.A.inwhereB.totheeastofwhichC.totheeastofitD.intheeastofthat2.Mybrother'spurse_______heput￥1000wasmissingonthebus.A.thereB.whichC.inwhichD.that3.Thefootballmatch_______thestudentscompetedyesterdaywasverywonderful.A.inwhichB.whichC.inthatD.that4.Thereason_______hewaslateagainwasthathewascaughtinatrafficjamintherushhour.A.whichB.inwhichC.forwhichD.ofwhich5.Hisglasses_______hecouldseenothingwastakenawaybyanau
