which引导的定语从句
关于which引导从句的小结： 关系代词which 一般指物，在定语从句中作主语、宾语或定语，既可引导限制性定语从句，又可引导非限制性定语从句。 1. 引导限制性定语从句 A shop should keep a stock of those goods which sell best. [ stock存货] 商店应存有最畅销的货物。 This is the family which is planning to move to the city 这是要搬进城里的一家。 2. 引导非限制性定语从句。 （1 ）用来指代一个句子。 Internet is so interesting, which makes all possible happen. 因特网是如此有趣，它使任何事都有可能发生。 （2 ）用来指代句子的一部分。 When deep in thought, which he often was, he would forget all around him. 他常常陷入沉思，这时他就会忘掉周围的一切。 （3 ）如果要引导两个非限制性定语从句，第二个which 前要加and. He bought a book, which was written by LuXun, and which he decided to give to his friend. 他买了本鲁迅写的书，他决定送给朋友。

(英语)英语定语从句练习题及解析
（英语）英语定语从句练习题及解析 一、定语从句 1．I hate people talk much but do little. A．whose B．whom C．who 【答案】C 【解析】 试题分析：句意：我讨厌那些说的多却做的少的人。句中所缺的是定语从句的关系词，先行词是people，指人，而且关系词在从句中做主语，故选C。whose既指人也指物，在从句中做定语；whom指人，在从句中做宾语；which指物，可做主语和宾语。 考点：考查定语从句 2．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】 句意：当我们说起文化的时候，我们指的是一群人共同拥有的生活方式。考查定语从句的引导词。根据句意：当我们说起文化的时候，我们指的是一群人共同拥有的生活方式。逗号后面的句中是含有定语从句的复合句，先行词是 life，表示“物”，用引导词 that，在从句中做宾语。what 不能引导定语从句。先行词是“人”，引导词常用 who。where 在定语从句中做地点状语。故选D。 【点睛】 引导定语从句的关联词包括关系代词和关系副词。关系代词有that, which, whose, who, whom, as；关系副词有when, where, why。关系代词和关系副词在定语从句中都充当一定的句法成份。关系代词在从句中充当动词的宾语时一般可以省略。 3．Linda will never forget the words her father told her. A．that B．who C．where D．what 【答案】A 【解析】 【详解】 句意：Linda将永远不会忘记她父亲告诉她的这些话。that关系代词，引导定语从句，先行词可以为人或物；who关系代词，引导定语从句，先行词为人；where是关系副词，引导定语从句，在从句中作地点状语；what什么，常引导名词性从句，不能引导定语从句。根据句子结构可知，这里是一个定语从句，修饰空前的the words，指物，且在从句中作宾语，故应选A。
where引导定语从句的用法
Where引导定语从句,先行词不一定都表 示地点 1、We will discuss a number of cases __ beginners of English fail to use the language preperly、A、which B、as C、why D、where 2、He was driving so fast as to get himself into a dangerous situation ___he is likely to lose the control over his car、 A、which B、as C、why D、where 两道题都选where ,但就是case, situation都不就是地点,如何理解？ 在“先行词不就是表示地点的名词”的前提下,如何判断就是否使用关系副词where来引导定语从句的问题就是一个高频考点。就就是说,关系副词where 所指代的先行词不只就是表示地点的名词。
用Where引导定语从句,先行词不一定都表示地点按照通常的理解,当where 引导定语从句时,它的先行词就就是表示地点的名词,但事实并不就是我们想象的那么简单。很多情况下,where所指代的先行词并不表示地点。请瞧以下几个例句: Other research, where siblings have been asked to say who their mother and father favor, suggests that mothers do tend to show a preference for their first-born son, but fathers often show great affection for their youngest daughters、 1、Remember that the best relationship is one where your love for each other is greater than your need for each other、请记住,最深的感情关系表现为彼此间的爱超过彼此间的需要。

定语从句(完整版)
定语从句 定语从句及相关术语 1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。 2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。关系代词有that, whi ch, who, whom, whose, as等；关系副词有where, when, why等。关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。 注：关系代词有主语.宾语之分。一般whom作为宾语。 4.定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用‘……的’表示。主要由形容词担任。此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任．单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。 先行词：被定语从句修饰的名词、代词称为先行词。 （一）限定性定语从句 一、关系代词（在句中作主语、宾语或定语） 1. that既可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语也可以省略。[eg：this is the book （which）you want。]而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置 2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢 3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括当先行词是anyt hing, everything, nothing , none等不定代词时，或者是由every, any, all, some, no, little, few, muc h等修饰时等，这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that 4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与of which 调换,表达的意思一样。 二、关系副词（在句中作状语） 关系副词=介词+关系代词 why=for which where=in/ at/ on/ ... which (介词同先行词搭配) when=during/ on/ in/ ... which (介词同先行词搭配) 1. where是关系副词，用来表示地点的定语从句。 2. when引导定语从句表示时间［注］值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。 By the time you arrive in London, we will have stayed there for two weeks. I still remembe r the first time I met her. Each time he goes to business trip, he brings a lot of living necessiti es, such as towels, soap, toothbrush etc。
定语从句练习题含答案
定语从句练习题含答案 一、定语从句 1．--Only You is a TV program is popular with most young people. --Yes, it is definitely true. A．that B．whose C．what D．who 【答案】A 【解析】 句意：——《只有你》是一个深受大多数年轻人喜爱的电视节目。——是的，这是千真万确的。本题考查定语从句的关联词，what不能引导定语从句，首先排除C；that的先行词是人或物，在定语从句中作主语或宾语；whose先行词指人或物，在定语从句中作定语；who的先行词是人，在定语从句中作主语。本句的先行词TV program指物，在定语从句中作主语，故答案为A。 点睛：在定语从句中，关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1） who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下： Is he the man who/that wants to see you? 他就是想见你的人吗?（who/that在从句中作主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 2） whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换），例如：They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。 3） which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如： Beijing is the place where （in which） I was born. 北京是我的出生地。 2．Norman Bethune was a great man _____ gave his life to help the Chinese people. A．which B．who C．whose D．what 【答案】B 【解析】 【详解】 句意：诺尔曼白求恩是一位伟大的人，他毕生致力于帮助中国人民。空格前名词man意为“人”，是先行词，后面是用来修饰这个名词，是定语从句部分，先行词指人，在定语从句中做主语，可以使用关系代词who/that，不能使用which（指物）/whose（指所属关系），what不能用来引导定语从句，故选B。
when 和 where 引导定语从句的用法
when 和 where 引导定语从句的用法 定语从句既是英语语法的一个重点，同时又是一个难点。说它是难点，主要难在两点上：一点是如何正确判断什么样的汉语句子要译为英语的带定语从句的复合句；另一点是定语从句的引导词较多(包括关系代词who, that, which, as 和关系副词when, where, why)，而且其用法也较复杂。那么到底什么情况下用when和where来引导定语从句呢？它们又该怎么用呢？下面就举例说明： 一、when：当主句中的先行词(即主句中被后面定语从句修饰的词)是表示时间意义的名词时，它只能作定语从句的时间状语，放在定语从句句首。如果定语从句的引导词是作该定语从句的主语或宾语，则要改用关系代词that或which来引导。例如： The days when we used foreign oil are gone. 我们用洋油的日子一去不复返了。 I'll never forget the day when I was born. (=I'll never forget my birthday.) 我永远不会忘记我出生的日子。 It happened in November when the weather was wet and cold. 这事发生在天气又湿又冷的十一月。 In the years that (which) followed, Marx kept on studying English and using it. 在这之后的几年中，马克思继续学习和使用英语。(that作定语从句"that followed"的主语) The day (that) I always remember in all my life is my birthday. 我一生中最难忘的日子是我的生日。(that作定语从句"that I always remember in all my life"的宾语，that可以省略)

as引导定语从句的用法
as引导定语从句的用法 as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which 引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思 (1) As is known to all, China is a developing country. (2) He is from the south, as we can see from his accent. (3) John, as you know, is a famous writer. (4) He has been to Paris more than several times, which I don’t believe. ================================ As 的用法例 1. the same…as；such…as 中的as 是一种固定结构, 和……一样……。 I have got into the same trouble as he (has). 例2. as可引导非限制性从句，常带有'正如'。 As we know, smoking is harmful to one's health. As is known, smoking is harmful to one's health. As是关系代词。例1中的as作know的宾语； 例2中，它充当从句的主语，谓语动词know要用被动式。 一、“as / which”特殊定语从句的先行成分 1. 形容词或形容词短语作先行成分, 具有形容词意义的介词短语也可以充当先行成分，如： My grandmother’s house was a lways of great importance to me, as my own is. 在一定的语言环境里，有些名词可以具有形容词的性质。这些名词主要是那些表示人的身份、职业、状态的名词。值得一提的是，在这些具有形容词性质的名词之后，引导定语从句的关系代词不能用who / whom. 2. 动词短语先行成分。 这种动词短语既可是限定形式也可是非限定形式。如果是动态动词短语，它们在从句中就一般有限定或非限定形式的替代动词do和as / which一起代替。do可以出现，也可以不出现，但不能用其它动词代替。 3. 句子作先行成分。 这句子可以是整个主句也可以只是主句中的一个从句。有时是连续几个句子，有时甚至可以是一个完整的故事。 二、“as/which”特殊定语从句在句中的位置 由于先行成分的构成成分不同，“as/which”特殊定语从句在句中的位置有以下几种情况：1. 形容词做先行成分时：形容词或形容词短语（含具有形容词性质的名词）作先行成分，“as / which”特殊定语从句置于先行成分之后。 2. 动词短语作先行成分时：动词短语作先行成分时，“as / which”特殊定语从句置于先行成分之后。但是，当从句中含有表示主观意志的插入成分时，“as”特殊定语从句可以移至句子之首。 3. 句子作先行成分时：“as”特殊定语从句的位置较灵活，可以置于先行成分之前、之中或之后。但如果先行成分是直接引语，“as”特殊定语从句多在先行成分之前。如果先行成分是否定句，“as”特殊定语从句与否定词的相对位置不同可以使它产生不同的意义。由于“as”特殊定语从句具有这一特点，所以有时它的位置不能随便移动。在非正式的文体里，“which”特殊定语从句可以出现在先行成分之中。
