While-class先行词作主语作宾语作定语人who/thatwhom/thatwhose物which/thatwhich/thatwhose定语从句一、定义1.在主从复合句中，对某一名词或代词起修饰作用的从句叫定语从句。被修饰的名词或代词叫先行词，引导定语从句的词叫关系词。2.关系词分为关系代词(that，which，who，whom，whose，as等)和关系副词(when，where，why等)两类。二、关系代词引导的定语从句1.who引导的定语从句[合作探究]

Thechildrenwhowereinjuredinthecaraccidentarebeingtreatedinthehospitalnow.目前，在车祸中受伤的孩子们正在医院接受治疗。Dannywasthemanwhowerescuedfromtheruins.丹尼是我们从废墟中救出来的那个人。[自主发现1]

who指人，在定语从句中可以充当主语、宾语。2.whom引导的定语从句[合作探究]

Roseistheperson(who/whom)youshouldcareabout.罗丝是你应该关心的人。Theboy(whom)theteacheroftenpraisesistheirmonitor.老师经常表扬的那个男孩是他们的班长。[自主发现2]

whom指人，在定语从句中作宾语，可省略，也可用who代替。3.whose引导的定语从句[合作探究]

Iknowthepersonwhosehousewasdestroyedintheearthquake.我认识那个人，他的房子在地震中被摧毁了。Helivesinaroomwhosewindowfacesnorth.他住在一个窗子朝北的房间里。[自主发现3]

whose既可以指人，也可以指物，表示“所属”关系，whose在定语从句中作定语。4.which引导的定语从句[合作探究]

Theyoungmanwasveryhappytogetbackthegoldring(which)hehadlostonthetrain.那个年轻人领回了在火车上丢失的金戒指，非常高兴。Thelittlegirlishavinganapplewhichisbigandred.小女孩正在吃一个又大又红的苹果。[自主发现4]

5.that引导的定语从句[合作探究]

Thenumberofpeoplethat/whocometovisitthiscityeachyearreachesonemillion.每年来参观这座城市的人数达100万。(that指人，作主语)Thesuitcasethat/whichliesonthegroundishers.地上放的那个手提箱是她的。(that指物，作主语)[自主发现5]

that既可指人，也可指物，在定语从句中作主语、宾语或表语，作宾语时可以省略。习惯上指人多用who/whom替代，指物多用which替代。[名师提醒]

(1)关系代词指代先行词在定语从句中充当主语、宾语、定语或表语，因此定语从句中不能再出现关系代词所替代的名词或代词。(2)关系代词在从句中作主语时不能省略，作宾语时可以省略。Part.3After-classAfter-classTranslatetheshortpassageintoEnglishusingrestrictiverelativeclauses.台风是发生在西太平洋上的一种极其强烈的风。台风过后,救援人员必须小心地在被碎片覆盖的地上行走。志愿者给被困在村子里的人送去了食物和其他补给品。这些村民将会记得一起度过灾难的救援人员和志愿者。没有找到父母的孩子会被邻居照看。一名央视记者正在采访一位家人从台风中幸存的女孩儿。After-class参考答案：Atyphoonisanextremelystrongwindthat/whichhappensinthewesternPacificOcean.Afterthetyphoon,therescueworkershadtowalkslowlyonthegroundwhichwascoveredwiththedebris.Thevolunteersdeliveredfoodsandothersuppliestothosewhoweretrappedinthevillage.Thevillagerswillremembertherescueworkersandvolunteerswithwhomtheywentthroughthedisaster.Thechildren
