高考语法填空(定语从句专项练习)
定语从句讲与练 一、定语的概念： 定语是用来修饰名词或代词的。比如： (先试试用横线划出下面短语中的定语，然后在后面的括号里注明是什么在作定语) a beautiful girl （ ） three boys （ ） a shoe factory （ ） Jim ’s father ( ) our teacher ( ) the man in the car （ ） the man standing at the door （ ） the man who is talking with Sam （ ） 二、定语从句的概念及主要特征： 1．定语从句：修饰某一名词或代词的从句叫定语从句。被定语从句修饰的词叫先行词；定语从句 一般紧跟在它所修饰的先行词之后；引导定语从句的词叫关系词。 请划出下列句子中的定语从句、先行词及关系代词： The man who is shaking hands with my father is a policeman. 2. 定语从句的主要特征： （1）先行词要在从句中充当一定的成分； （2）what 永远不能引导定语从句； （3）翻译时先译从句，翻译成“…….的” 三、定语从句的基本用法： 定语从句 的引导词 关系代词 关系 副词 where (地点状语) when (时间状语)why (原因状语) （一）关系代词引导的定语从句 1．who 指人，在定语从句中作主语，有时也作宾语。 The boys who are playing football are from Class One. 分析：关系词who 在从句中作主语。 Those who want to go to the museum must be at the school gate at 7 tomorrow morning. 分析：关系词__________ 在从句中作________。 Yesterday I helped an old man who had lost his way. 分析：关系词_________在从句中作________。 That is the teacher who teaches us physics. 分析：关系词__________ 在从句中作________。 You needn ’t talk to the people who you don ’t like talking to. 分析：关系词______在从句中作________。 2．whom 指人，在定语从句中做宾语，常可省略。 Mr Liu is the person ( whom ) you talked about on the bus. 分析：关系词_____ 在从句中作________。 Li Ming is just the boy ( whom ) I want to see. 分析：关系词__________ 在从句中作________。 The professor ( whom ) you are waiting for has come. 你正在等的教授已经来了。 分析：关系词__________ 在从句中作________。 注意：关系代词whom 在口语或非正式文体中常可用who 来代替，也可省略。 The man ( whom / who )you met just now is my old friend. 3. whose 通常指人，也可指物，在定语从句中做定语。 I visited a scientist whose name is known all over the country. 分析：关系词____在从句中作________ He has a friend whose father is a doctor. 译成汉语：_________________________________ 分析：关系词_________ 在从句中作________。 I lost the book whose cover was blue. 分析：关系词_________ 在从句中作________。 We live in a house whose windows face the south. 译成汉语:_________________________ 注意：指物时，常用下列结构来代替： The classroom whose door is broken will soon be repaired.＝The classroom the door of which is broken will soon be repaired. Do you like the book whose cover is yellow?＝Do you like the book the cover of which is yellow? 自己总结一下：在定语从句中，whose + 名词＝ ___________________________ 4．which 指物，在定语从句中做主语或宾语，做宾语时常可省略。 Football is a game which is liked by most boys. 分析：关系词__________ 在从句中作________。 The factory which makes computers is far away from here. 分析：关系词______在从句中作________。 He likes to read books which are written by foreign writers. 译成汉语:____________________ 分析：关系词__________ 在从句中作________。 The house which is by the lake looks nice. 分析：关系词__________ 在从句中作________。 This is the pen ( which ) he bought yesterday. 译成汉语：___________________________ 分析：关系词__________ 在从句中作________。 The film ( which ) they went to see last night was not interesting at all. 他们昨晚看的电影一点意思也没有。分析：关系词__________ 在从句中作________。 5．that 引导定语从句时，既可以指人，也可以指物。指人时，相当于who 或whom ；指物时，相当于which.。在定语从句中作主语或宾语，作宾语时常可省略。
英语定语从句专项训练100(附答案)含解析
英语定语从句专项训练100(附答案)含解析 一、定语从句 1．Lily doesn’t know ________ she and her friends can do to help the little boy ________ parents have left their hometown for making money. A．that; whose B．how; who C．what; who D．what; whose 【答案】D 【解析】 that引导宾语从句一般不充当句子成分，只起连接作用；how引导宾语从句，一般做方式状语；what引导宾语从句，做从句的逻辑主语或者宾语。句意：莉莉不知道她和她的朋友们能做什么来帮助这个小男孩，他的父母离开家乡去挣钱了。结合语境可知前文是宾语从句，what，什么，充当宾语从句谓语动词do的逻辑宾语。下文为定语从句，the little 宾语boy和parents是逻辑上的所有关系，故引导词用whose，选D。 考点：英语从句 2．The last place _______ we visited was Chaoshan Custom Museum. A．where B．that C．when D．why 【答案】B 【解析】 句意：我们参观的最后一个地方是潮汕风俗博物馆。根据句子结构可知，这里考查的是定语从句，where关系副词，指地点；that关系代词，先行词为物；when关系副词，指时间；why关系副词，指原因。定语从句中visited后缺少宾语，故应填关系代词，选B。 3．The leaders from eight countries attended the Shanghai cooperation organization summit in Qingdao got the welcome of the Chinese people. A．whom B．what C．who D．which 【答案】C 【解析】 【详解】 句意：出席上海合作组织青岛峰会的8国领导人受到中国人民的欢迎。考查关系代词辨析。what不是关系词，可排除。whom和who都用于先行词是人时，但whom用作宾语，who用作主语或宾语；which用于先行词是物时。本句先行词The leaders是人，可排除which；关系词在从句中做主语，可排除whom。根据句意结构和语境，可知选C。 4．When we speak of culture, we mean a way of life_________ a group of people have in common. A．what B．who C．where D．that 【答案】D 【解析】 【详解】

定语从句语法与练习
定语从句 一、有关定语从句的概念 (1)定语从句：就是在复合句里充当定语的从句，它通常紧靠在所修饰的名词或代词后面。 (2)先行词：就是被定语从句修饰的名词或代词。 (3)关系词：引导定语从句的词叫关系词。 关系词有关系代词who, whom, whose, which和that等； 关系副词有when, where, why等。 关系词不仅起连接作用，而且还代表先行词并在定语从句中担任某一句子成分，关系代词作主语、宾语、定语、表语等，关系副词作状语。如： This is the book that my father bought me yesterday. 这就是我父亲昨天帮我买的那本书。 说明：句中修饰the book的that my father bought me yesterday就是定语从句；被定语从句所修饰的the book这是先行词；代表the book的关系代词that在定语从句中作bought的直接宾语。 The time when he arrives is not known. 他到达的时间还不知道。 说明：句中when he arrives是定语从句，被定语从句修饰的the time是先行词，关系副词when 作时间状语。 二、关系代词的一般用法 先行词是人，在从句中作主语用who，作宾语用whom或who，作定语用whose；先行词是物，在定语从句中作主语或宾语都用which，作定语用of which或whose均可。在限制性定语从句中which, who, whom都可用that代替。关系代词作宾语时常被省略。 This is the man who helped me yesterday. 这就是昨天帮助我的那个人。(作主语) The teacher (who/whom/that) you want to see is coming. 你要见的老师来了。(作see的宾语，可以省略) I met a boy whose father was an astronaut. 我认识一位男孩，他的父亲是宇航员。(作定语) Here is the coat which/that will be bought for you. 这是一件买给你的衣服。（作主语） This is the factory (which/that) we visited last year.这就是我们去年参观的那家工厂。(作visited 的宾语，可以省略) He has a book whose cover (=the cover of which) is very beautiful. 他有一本封面非常漂亮的书。 三、关系副词的一般用法 关系副词有when, where, why，在定语从句中作状语，分别表示时间、地点和原因。 when的先行词通常是time, day, season, age, occasion等时间名词； where的先行词通常是place, city, town, village, house, case, situation, scenes等地点或情形名词； why的先行词只能是reason。 关系副词when和where有时可用“介词＋which”代替，why可用for which代替。 如：There are occasions when (=on which) one must yield. 任何人都有不得不屈服的时候。Beijing is the place where (=in which) I was born.北京是我的出生地。 Is this the reason why (=for which) he refused our offer?这就是他拒绝我们帮助他的理由吗？ 注意：先行词虽然是时间或地点，但若在定语从句中作主语或宾语时，要用关系代词。(1)The factory where his father worked has closed. 他父亲曾工作的那家工厂关闭了。(作状语) 比较：The factory which/that was built in 1978 has closed. 1978年建的那家工厂关闭了。(作主
