train,that was going to Shanghai,was late,.(,that,指代物,the train,，在从句中作主语，不能省略,),去往上海的那趟列车晚点了。,15,The man(,that,),you saw just now,is our teacher.,（,that,指代人,the man,，在从句中作宾语，可省略）,你刚刚看到的那个人是我们的老师。,16,2.which,指物，在从句中作主语或宾语，作宾语时可省略，可和,that,换用,。如：The train,which/that was going to Shanghai,was late.(which,指代物,the train,，在从句中作主语，不能省略,),The book,(which/that)you want,is on the desk.,（,which,指代物,the book,在从句中作宾语，可省略）,你想要的那本书在桌子上。,17,下面几种情况不能用,which,，而要用,that,引导定语从句：,（,1,）先行词为,all,much,little,few,something,anything,everything,nothing,等时。如：,All,that,can be done has been done.,能做的都做了。,18,（,2,）先行词被,all,any,every,few,little,no,some,等修饰时。如：,I have read all the books(,that,)you gave me.,我已读完了你给我的所有的书。,19,（,3,）先行词被序数词或形容词的,最高级,修饰时。如：,This is one of the best films(,that,)I have ever seen.,这是我看过的最好的电影之一。,20,（,4,）先行词被,the only,the very,the last,修饰时。如This is the very book(,that,)I am after.,这正是我要找的书。,21,（,5,）先行词既有人又有物时。如：,He spoke of the men and the things(,that,)he had seen abroad.,他谈到他在国外见到的人和事。,22,3.who,whom,指人，在从句中分别作主语和宾语，可和,that,换用。,whom,作宾语时也可用,who,替代，也可省略。,如：,The boy,who/that helped you,is my classmate.,（,who,指,the boy,在从句中作主语，不能省略）,帮助你的男孩是我的同学。,23,The man(,whom/who/that,),you saw just now,is our teacher.,你刚才见到的那个人是我们的老师。,24,4.whose,指人或物，在从句中作定语。当修饰物时，相当于“名词,+of which”,。,如：,Here is the girl,whose mother works in this shop,.,就是那个母亲在这家商店工作的女孩。,25,He lives in a room,whose window,(=the window of which),faces south,.,他住在窗户朝南的那个房间里。,261.,关系代词,which,whom,在定语从句中作介词的宾语时，可以跟介词一起放在主句和从句之间，这时不用,that,；也可以把介词放在从句中有关动词的后面，这时也可用,that,代替,which,或,whom,，也可省略。如：,“,介词关系代词,”,引导的定语从句,27,This is the room,in which we lived last year,.,或,This is the room(,which/that,),we lives in last year,.,这是我们去年住的房间。,Whos the man,to whom you talked just now,?,或,Whos the man(,whom/that,),you talked to just now,?,刚才和你谈话的那个人是谁？,28,2.“,介词关系代词”中介词的选择,根据从句中谓语动词的搭配习惯。如：,This is the book,about,which I often,talk,.,=This is the book,of,which I often,speak,.,这是我经常谈到的那本书。,29,根据先行词的搭配习惯。如：,I remember the day,on,which I first met him.,我还记得我第一次见到他的那天。,I remember the days,during,which I lived there.,我还记得我住在那儿的那些日子。,30,同时考虑动词和介词的搭配关系及介词和名词的搭配关系。如：,He made a hole in the wall,through,which he could see what was happening inside the house.,他在墙上弄了个洞，通过这个洞他能看到房子里正发生的一切。,31,关系副词,when,where,why,引导的定语从句,1.when,指时间，在从句中作时间状语,，可用,“,介词,（,on,in,at,during,等）关系代词,”,代替。如：,Ill never forget the day,when,(=on which,)I joined the League,.,我永远都忘不了我入团的那一天。,32,2.where,指地点，在从句中作地点状语,，可用“介词（,in,at,等）关系代词”代替。如：,This is the factory,where,(=in which),we stayed last year,.,这就是我们去年待的工厂。,33,3.why,指原因，在从句中作原因状语,，可用“介词,for,关系代词”代替。如：,I dont know the reason,why,(=for which),he came late,.,我不知道他迟到的原因。,34,注意：,当先行词为表时间、地点的词时，有时不用,when,where,，而用,which,或,that,。试比较：,（,1,）,This is the factory(which/that)we visited last year.,这是我们去年参观的工厂。,（,2,）,This is the school,where,we studied last year.,这是我们去年上过学的学校。,35,要正确把握关系代词和关系副词的区别，关键是看引导词在定语从句中所起的作用，特别是要注意定语从句中谓语动词的特点。如,（,1,）中动词,visit,是及物动词，由此判断引导词作宾语；,（,2,）中,stay,为不及物动词，由此判断引导词作状语。,36,the way,后的定语从句,以,the way,为先行词的限制性定语从句一般由,that,或,in which,引导，通常还可以省略。如：,I dont like the way(that/in which)you laugh at her.,我不喜欢你笑话她的那种方式。,37,1.,限制性定语从句和主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。如：,I was the only person in our office,who was invited,.,（去掉定语从句，主句意思不完整）,我是办公室里唯一被邀请的人。,限制性定语从句和非限制性定语从句,38,2.,非限制性定语从句与先行词关系不密切，去掉定语从句，句子意思仍然完整。形式上用逗号把从句和主句隔开。非限制性定语从句不能用,that,引导。如：,Toms father,who is over sixty,still works hard day and night.,汤姆的父亲，,60,多岁了，现在仍然夜以继日地工作。,39,Tom studies hard and is ready to help others,which his parents expected,.,汤姆努力学习而且总是乐于助人，这点是他父母所希望的。,
