(完整版)as和which引导非限制性定语从句的区别
As与which引导非限定性定语从句辨析
1.as引导非限制性定语从句，只代表主语或主句的一部分所表达的意思(不能指代某个名词或代词)，可以放在主句前，后或中间，在从句中作主语或宾语、例如：
As is known to all, he is the best student in our class. (as指代整个句子，作主语，置于句首)
He opposed the idea, as could be expected. (as 指代整个句子，作主语，置于句末)
As we all know, he studies very hard. (as 指代整个句子，作宾语，置于句首) Taiwan is, as you know, an inseparable part of China. (as指代整个句子，作宾语，置于句中)
2.在非限制性定语从句中，which和as引导定语从句时的区别：
a. which引导的从句不能放在主句前，而as引导的从句则既可以放在主句前，也可以放在主句后。例如：
As (正确) is often the case, he is absent.
Which (错误)
He saw the girl, as (正确) He had hoped.
Which （正确）
b.用能做关系代词，as和which都可以指代一个句子，但as有“正如”、“就像”之意，which则没有此含义。
He is a foreigner, as I know from his accent. (as指代一个句子，意为“正如”、“就像”)
He has to work on Sunday, which he doesn’t like. (which指代一个句子，没有“正如”、“就像”)
c.当从句的谓语动词是be或相当于联系动词的seem, become等时，可用as或which作主语。但当从句的谓语是行为动词时，只能用which作主语。例如：
He married her, as (正确) was / seemed natural.
Which （正确）
He saw the girl, as (错误) delighted him.
Which （正确
as引导的非限制性定语从句
as引导的非限制性定语从句： 1： as引导限定性定语从句，常用于以下句式，其中关系代词在从句中担当主，宾，表语： ①so/as/such+名词+as…像……一样的，像……之类 : We have found such materials as are used in their factory. These houses are sold at such a low price as people expected. This book is not such as I expect. Such things as you described are rare now. He isn’t such a man as you described. He is such a lazy man as nobody wants to work with =he is such a lazy man that nobody wants to work with him. I want to have such a dictionary as he has. I have bought such a watch as was advertised on TV. Mount Wuyi is such an attractive place of interest as everyone likes to visit. Such money as he earned was spent on spirits and tobacco.

I like the same book as you do . I shall do it in the same way as you did. This is the same pen as I lost yesterday. Is this the same mosquito as bit you just now? 2: as引导的非限定性定语从句，指代整个主句的内容，但不同于which的是，它引导的定语从句既可以位于主句的前面，也可以位于主句的后面。它的意思是“正如”，在这些从句中as作主语或宾语。经常使用的短语又： as(it) seems likely, as (it) often happens, as (it) was printed out, as (it) was said earlier, as I remember (it), as I unde rstand (it), as (it) appears, as is known, as is said, as is reported, as announced, as we had expected, as everybody c an see, as is mentioned above. 如： As we all know, china is a developing country..

As is known to everybody, the moon travels round the earth once everyone =the moon travels round the earth once every month, as/which is known to everyone.
as与which引导定语从句的用法辨析
as与which引导定语从句的用法辨析 一、as和which都能引导的定语从句 当非限定性定语从句置于句末时，as和which都可用来引导这个定语从句。但含义有区别。 1、 Dorothy was always speaking highly of her role in the play, _______ , of course, made the others unhappy. A. who B. which C. this D. what 2、The number of senior high school students is increasing, _______ is mentioned above. A. that B. it C. such D. as 二、只能用which引导的定语从句 1. 在限定性定语从句中。例如： The project _______ a British businessman has invested in is under construction at present. A. which B. as C. what D. why 2. “介词+关系代词”引导定语从句时，只能用which。例如： Recently I bought an ancient Chinese vase, _______ was very reasonable. A. which price B. the price of which C. its price D. the price of whose 3. 当后置的非限定性定语从句是否定结构时，只能用which引导。例如： The result of the experiment was very good, _______ we hadn't expected.

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
定语从句中where和which的区别
定语从句中where和which的区别
定语从句中where和which的区别 1.This is the factory_________we visited yesterday. 2.This is the stable__________Jesus Chirst was born. 1,which 2.where 分析：关键是看从句中的动词。如果是及物动词（顾名思义，就是必须要接物做宾语的动词，或能用做被动的动词），则表明从句缺宾语，修饰人用who/whom/that。修饰物用that/which. 如动词是不及物（顾名思义就是不需要接物做宾语的或要接宾语时前面必须要加介词的，即用介宾的动词），则说明从句不缺宾语，可能是状语(或介宾）。表地点用where.时间用when. 如题1：从句的动词是visit，我们说参观某个地方说：visit some place。而不说visit in the place所以visit是及物动词。所以缺宾语，修饰物故用which. 如题2，我们说出生于某地用be born in，如：i was born in beijing 而不说i was born
beijing.故说明born 后不直接跟宾语，应用介宾，或关系副词（where/when)所以此处填in which 也是正确的。 所以在平时的练习中应注意动词的及物于不及物性1这是解决这类题的关键之一。扩展练习： 1.These are the days ____ I spent with my mom. (when） 2.These are the times _____ I experienced .（which） 英语定语从句that ,where ,which 的区别 例如：(1) I love places ____ the people are really fridendy A.that B.which C.where D.who (2) This is the place ____ I have ever visited there B.whom C.he D.which (3).This is the house ____ I want to buy A.In which B.that C.what D.that (4)this is the museum ____ we visited last year A.where B. in which C.which D.in that
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）
as和which的用法区别
非限制性定语从句中的as和which ■as 和which的相同点 (1) as 和which都可引导非限制性定语从句，放在主句之后；在非限制性定语从句中充当从句的主语、宾语或表语。如： Tom has found a good job, as / which we all hope. 汤姆找到了一件好工作，这正是我们大家所希望的。 (2) as 和which都可代表整个句子的内容或主句中的某一成分。如： His mother is ill, which makes him very sad. 他母亲病了，这件事情使他很难过。 He has made great progress, as / which makes us very happy. 他进步了，这使得我们很高兴。 以上两句中的as / which都指前面整个句子的内容。 Though he has lots of money, he still rides his old bike, which was bought ten years ago. 尽管他很有钱，但是他还骑着他的旧单车，这单车是十年前买的。 There you can meet many writers as you have ever read in books. 在那里，你可见到你在书中所读过的很多作家。 ■as与which的区别 (1) 当先行词前面有so + adj. + a / such + (a) + adj. , the same等词修饰时，引导词只能用as，而不用which。如： She is so nice a girl as we all like. 她是个我们大家都喜欢的如此好的女孩。 It is such an interesting book as we all want to read. 它是本我们大家都想读的有趣的书。上面两句中的as就不能用which替换。 (2) as 在从句中常作宾语；作主语时，从句的谓语动词常为系动词，即：系表结构或被动结构。如： As is said above, he has conquered the difficulty. 正如上面所说，他征服了困难。
(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。

关系代词as和which 引导的定语从句 as和which引导非限制性定语从句，有相同之处也有不同之处。具体情况是：1. As和which都可以在定语从句中做主语或者宾语，代表前面整个句子。 He was honest, as/which we can see. 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 which 指代整个句子不可置于句首只能位于主句后。 1. They d idn’t come to school on time, which made the teacher angry. 2. The sports meeting was put off, which astonished (吃惊）us greatly. 3. His father died last year, which made it impossible for him to go to school. 4.

China is a great country with a long history, a s is known to all. 注意:当主句和从句存在逻辑上的因果关系时,主句与从句有因果或并列，从句谓语动词是“系动词+adj" 使用which Our class has won the volleyball match, which is inspiring. Tom suddenly fell ill, which made us sad. Tom突然病倒，这使得我们很伤心。Which引导的非限制性定语从句在从句中做主语，其代指整个主句，主从句的关系是因果关系，因为他的病，所以我们伤心。 The road was too slippery, which caused lots of accidents. 路太滑了，以至于引起了很多事故。which引导的非限制性定语从句在从句中做主语，其代指整个主句，主从句的关系是因果关系，因为路滑，所以出事。 (1) As is known to all, China is a developing country.

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。
