2018高中定语从句专项讲解练习 1 / 4 第四章 定语从句 【概念】定语从句,也称为关系从句或形容词性从句,由关系代词或关系副词引导,用来限制,描绘或说明主句中

的某一个名词或代词(有时也可以说明整个主句或主句中的一部分),即句子作定语.定语从句所修饰的对象被称为先行词.定语从句按其作用可分为限制性定语从句和非限制性定语从句. 关系代词和关系副词的作用有: ①连接作用:引导从句并同时连接主句和从句 ②替代作用:在从句中替代它前面的先行词 ③作成分:在从句中充当句子成分.如:主语(who,that,which);宾语(who,whom,which,that);表语(that,as);定语(whose,...of whom/which);时间状语(when),地点状语(where)和原因状语(why). 说明:关系代词在从句中宾语时可省略,作其他成分时一般不可省略. (一) 关系代词的用法 1.关系词用法分类 关系词 例词 所修饰的先行词 在从句中所作的成分 省略情况

关系代词 who 人 主语,宾语,表语 作宾语时可省略

whom 人 宾语 可省略

which 物 主语,宾语,表语 作宾语时可省略

that 人或物 主语,宾语,表语 作宾语时可省略

whose 人或物 定语 不可省略

关系副词 when 时间名词 时间状语 不可省略 where 地点名词 地点状语 不可省略

why 原因名词 原因状语 不可省略

2.关系代词that和which的用法 ⑴限制性定语从句中,必须用关系代词that的情况: ①当先行词是不定代词all,much,little,something,everything,anything,nothing,none等时. Do you have anything that you want to say for yourself? You should hand in all that you have. ②当先行词被the only,the very,any,few,little,no,all等词修饰时. This is the very person that I'm waiting for. The only thing that we can do is to give you some advice. ③当先行词是形容词最高级或先行词的前面有形容词最高级修饰时. This is the best way that has been used against pollution. This is the most interesting film that I've ever seen. ④当先行词是序数词或它前面有序数词修饰时. This train is the last that will go to Suzhou. What is the first American film that you have seen? ⑤当先行词既有人又有物时. Do you know the things and persons that they are talking about? ⑵当先行词指物时,定语从句中关系代词必须用which的情况: ①在非限制性定语从句中,只用which,不用that. Helen was much kinder to her youngest son than to the others,which,of course,made the others envy him. ②当定语从句中的介词提前时,只用which,不用that. This is the school in which I once studied. 3.关系代词who/that,whom和whose的用法. 当先行词指人: ①在定语从句中作主语时,用who/that,不可省略 ②在定语从句中作宾语时,用whom/who/that,可以省略 ③在定语从句中作定语时,用whose,不可省略 She is the girl who/that lives next door.(先行词在定语从句中作主语) That's the girl(whom/who/that)I teach.(先行词在定语从句中作宾语) This is the scientist whose achievements are well known.(先行词在定语从句中作定语) This is the house whose window broke last night. =This is the house,the window of which broke last night. =This is the house,of which the window broke last night. 4."介词+关系代词"引导的定语从句 ⑴当介词放在关系代词的前面时,关系代词常用which或whom,关系代词不能省略. Is this the house in which Shakespeare was born? He paid the boy $10 for washing ten windows,most of which hadn't been cleaned for at least a year. In the dark street,there wasn't a single person to whom she could turn for help. ⑵在限制性定语从句中,当介词位于定语从句的末尾时,可用that/which(指物),that/whom/who(指人)作介词的宾语,而且作介词宾语的关系代词可以省略. that This is the hero who we are proud of. whom(可省略)

that This is the pen which I wrote the letter with. (可省略)

⑶"介词+which/whom+不定式"结构 The beggar has no money with which to buy food. =The beggar has no money to buy food with. =The beggar has no money that he can buy food with. 5.关系代词as引导的定语从句 关系代词as既可以引导限制性定语从句,也可以引导非限制性定语从句,as在从句中作主语,宾语或表语. as引导限制性定语从句时常用于下列句式: such+名词+as...像....一样的,像....之类的 ⑴ the same+名词+as...和....一样的

其中关系代词as在从句中担当主语,宾语或表语. We have found such materials as are used in their factory.(as作主语) These houses were sold at such a low price as people expected.(as作宾语) He is not the same man as he was.(as作表语) ⑵...such as.. such为代词,意为"这样的人或物",as引导定语从句并在从句中担当成分,定语从句修饰先行词such. This book is not such as I expect.(as作宾语) 6.关系代词as与which引导非限制性定语从句时的区别 as引导的非限制性定语从句,既可在主句前,又可在主句后,有时还可插入主句中,而which引导的非限制性定语从句只能置于主句之后.相同的是两者都可替代整个主句的内容. The weather turned out to be very good,which was more than we could expert. As is known to everybody,the moon travels round the earth once every month. =The moon travels round the earth once every month,as/which is known to everybody. (二) 关系副词的用法 1.当关系词在定语从句中作状语时,要用关系副词.其中when=表时间的介词(in,at,on,during)+which;where=表地点的介词(in,at,on,under)+which;why=表原因的介词(for)+which. I still remember the day when I first came to Beijing.(when=on which) Can you tell me the office where he works?(where=in which) Do you know the reason why he is absent?(why=for which) 2.有时先行词为抽象名词situation,stage,point等,表示模糊化的地点,可用where引导定语从句. The accident has reached a point where both their parents are to be called in. (三) 定语从句用法的其他要点 1.定语从句中的谓语动词与先行词保持一致 当引导定语从句的关系代词在从句中作主语时,定语从句中的谓语动词在人称,数方面应该与先行词保持一致. ⑴one of+复数名词+关系代词+动词复数形式. Titanic is one of the most wonderful movies that have been produced in Hollywood. ⑵the only one of+复数名词+关系代词+动词单数形式 Titanic is the only one of these wonderful movies that has been produced in Hollywood. ⑶当关系代词as与which引导非限制性定语从句,修饰主句内容时,若as与which作主语,则从句的谓语动词用单
