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。
练习1. [1. board董事会 2. data资料,数据 3. shareholder 【英】股东 4. on behalf of代表 5. guard保护] The ability to guard customer data is the key to market value, which the board is responsible for on behalf of shareholders. which的先行词是谁？ 译文：保护客户资料的能力是市场价值的关键，董事会代表股东对市场价值负有责任。 【难点小结：1.介词短语 2.which 的先行词 3. 非限制性定语从句有时要翻译成一句话】 例2. 【1.semiconductor半导体 2. casualty伤亡，灭亡，覆灭 3.< A sit at the heart of B> A是B的核心】
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。
限制性定语从句与非限制性定语从句
限制性定语从句与非限制性定语从句 2．关系代词which与as引导非限制性定语从句的区别。 （1）which与as都可以引导非限制性定语从句，which引导定语从句要置于先行词后面，而as引导的定语从句位置相对灵活，可放在句首，也可以放在句后 eg.正像他所意识到的那样，我对他非常有用 As he realized, I was very useful to him. 空气，众所周知，是一种气体 Air, as we know, is a gas. 他是个外国人，正像我从他口音判断的那样。 He was a foreigner, as I know form his accent. 他又来晚了，这一点使老板很生气 He came late again, which made his boss angry. (2)当定语从句位于主句后面，纯粹表示主句所述的内容，往往用which；当定语从句中有“如同……那样”的含义时，用as比用which更常见。 Eg.妈妈老把我当成小孩对待，让我无法忍受 Mummy always treats me just like a baby, which I can’t bear. 事与愿违，这是常有的事 Things will turn out contrary to on e’s wishes, as is often the case. (3)“介词+关系代词”结构的定语从句，必须用which,不能用as. Eg.我们周围有很多氧气，没有他们我们无法生存 There is a great deal of oxygen around us, without which we could not live. 3．引导限制性定语从句时which与as的区别 定语从句前面有such, as, the same 时，引导定语从句的关系代词用as,不用which. Eg 所需要的字典有许多都有了
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。
as 引导定语从句, 在定语从句中作主语、宾语、表语
as的用法: (as引导定语从句,在定语从句中作主语、宾语、表语) (1)如为限制性的，多用于the same …as ; the same as；such …as …; as many/muchas；so …as等结构中。如： 1. I have the same book as you (have).我有一本和你的一样的书。 Her attitude to him was quite the same as it had always been. (关系代词as和指示代词same连用,在从句中用作表语,先行词是same.) 2.---Why didn't you mention that in face of the police just now? --- I thought it was such a minor detail as was hardly worth mentioning. We will only discuss such problems as have something to do with our own interests.Don't do such things as you are not sure about. There is no such place as you dream of in all this world. 比较： I live in the same house that he used to live in. I'm wearing the same shirt as you wore yesterday. 比较： Here is so big a stone as no one can lift.（定语从句） Here is so big a stone that no one can lift it.（结果状语从句） (2)如为非限制性的，多单独引导一个定语从句，这种定语从句可置于句首，句中或句尾，译为"正如，这一点"。（动词常为know, see, expect, point out, etc.） 1. As we all know, smoking is harmful to one's health . (as作宾语) =As is known to all, smoking is harmful to one's health .（as作主语）
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。
(完整版)限制性定语从句与非限制性定语从句的六点区别
限制性定语从句与非限制性定语从句的六点区别 区别一：形式不同 限定性定语从句主句和从句之间不用逗号隔开，口语中使用时也不停顿；而非限定性定语从句与主句之间通常有逗号隔开，口语中使用时有停顿。 区别二：功能不同 限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意不完整或概念不清；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意仍然清楚、完整。如： People who take physical exercise live longer. 进行体育锻炼的人活得长些。(若把从句去掉句子就失去意义) His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。(若把从句去句子意义仍然完整) 区别三：翻译不同 在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。如： He is the man whose car was stolen. 他就是汽车被窃的那个人。 I’ve invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。 区别四：含义不同 比较下面的两个句子： I have a sister who is a doctor. 我有一个医生的姐姐。(姐姐不止一个) I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。(只有一个姐姐) 区别五：先行词不同 限定性定语从句的先行词只能是名词或代词，而非限定性定语从句的先行词则可以是名词或代词，也可以是短语或句子；另外，当先行词为专有名词或其他具有独一无二性的普通名词时，通常要用非限制性定语从句，而不用限制性定语从句。如： Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(which指drive too fast) He changed his mind, which made me very angry. 他改变了主意，这使我很生气。(which 指整个主句)
which在非限制性定语从句的用法
非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，将非限定性定语从句放在句子中间，其前后都需要用逗号隔开。 which引导的非限制性定语从句。 关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句，在从句中作主语、动词宾语、介词宾语或表语。 ① which指代主句中的名词，被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及表示职业、品格等的名词。 如：These apple trees，which I planted three years ago，have not borne any fruit. 这些苹果树是我三年前栽的，还没有结过果实。 She is an artist，which I am not. 她是一位艺术家，而我不是。 Water，which is a clear liquid，has many uses. 水是一种清澈的液体，有许多用途。 The two policemen were completely trusted，which in fact they were. 那两个警察完全受到信任，事实上，也真是如此。 ② which指代主句中的形容词。 如：She was very patient towards the children，which her husband seldom was. 她对孩子们很耐心，她丈夫却很少这样。 She is always careless，which we should not be. 她总是马虎大意，我们可不应该这样。
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)

非限制性定语从句中的关系代词which和as用法辨析
龙源期刊网 https://www.360docs.net/doc/f218611727.html, 非限制性定语从句中的关系代词which和as用法辨析 作者：邵玉金 来源：《新高考·高三英语》2013年第03期 请看下面两道题： ① He has won the game， was expected. ② He has won the game， was unexpected. A. that B. which C. it D. as 以上两题选项中均含有关系代词which和as，该选哪一个呢？现就以下几个方面来谈一谈它们的区别（本文所谈的which和as是指引导非限制性定语从句中的关系代词which和as）。 一、位置关系：关系代词which不能放在句首；关系代词as 既可以放在句首也可以放在 句末，甚至还可以放在句中。 1. As is known to all， he studies very hard.（不可用which） 2. New concept English is intended for foreign students， which is known to all of us.（which 不可放在句首，这里也可以用as） 3. He， as you know， is clever. 二、内涵关系：as有“正如”、“就像”之意，即主从句意义一致；which 则没有此意。 He is a foreigner from North America， as I know from his accent. （as表示“正如”之意） Tom is so busy that he has to work at weekends，which he doesn’t like. 三、先后关系：as引导的多为经常性行为，或先于主句发生的动作；which引导的多表示发生在主句之后的行为。
