英语as与which引导非限制性定语从句之区别

英语as与which引导非限制性定语从句之区别：练习题。

两者之间的区别在于：1. which引导的定语从句只能位于主句后，但as引导的从句可位于主句前、中、后。

如：David, as you know, is a photograopher. (不可用which)Li Ming is late, as is often the case. (不可用which)2. as在定语从句中作主语时，从句谓语通常要有be或别的系动词，但which不受此限制。

如：Li Ming was late, which (=and this) made Mr. Zhang very angry. (不可用as)3. as引导的定语从句只表示一个众所周知或意料之中的事，但which不受此限制。

如：He married her, which was unexpected. 他和她结婚了，这是出乎意料的。

(不可用as)4. as有“正如”之意，而which则意为“这(件事，一点)”，可用and this/that/it来代替。

5. as多用于固定搭配中：as is often the case(这是常有的事)，as was expected(不出所料)，as often happens(正如经常发生的那样)，as is known to all(众所周知)，as has been said before(如上所述)，as is mentioned above(正如上面所提到的)等。

as和which在非限制性定语从句中的区别

as和which在非限制性定语从句中的区别作者：王艳霞来源：《新课程·教师》2010年第10期在非限制性定语从句中as和which是经常使用的关系代词,他们都可以指代整个主句,相当于and this或and that,但它们还是有各自的使用规则,有所区别。

一、从意义上看,as一般指代人们日常生活中都知道的常识性的东西,因而常被译成“正如”;而which代指前面主句的内容,意为“这一点”。

二、从位置上看,as引导的非限制性定语从句,既可放在主句前又可置于主句后,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。

例如:The weather turned out to be very good,which was more than we could expect.结果天气非常好,这一点我们没有料到。

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.众所周知,月亮每月绕地球转一次。

三、当定语从句放在主句后面时,一般用as和which都可以,但也不总是这样,例如:1.当非限制性定语从句是否定句或表示否定意思时只能用which。

如:He came here very late,which was unexpected(not expected).他迟到了,这是意料之外的。

2.当as在从句中作主语时,后面常接动词的被动语态,如be known、be said、be reported、be announced等。

如果从句是主动语态,一般用which作主语,如:She has been absent again,as is expected.她又缺席了,这在意料之中。

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。

二、只能用which引导的定语从句1. 在限定性定语从句中。

2. “介词+关系代词”引导定语从句时，只能用which。

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。

三、只能用as引导的非限定性定语从句1. 置于句首时，非限定性定语从句只能用as引导。

2. 在the same...as 结构中，意思是“像……那样的”。

3. 在as...as结构中，意思是“像……那样的”。

as作从属连词用时，可以引导五种状语从句。

现归纳如下：1. as表示“当……的时候”，引导时间状语从句，多强调主句和从句中的动作或状态同时发生，从句可放在主句前，也可放在主句后。

例如：As I waited at the stop，I heard a big noise.She rose up as he entered.2. as表示“因为”、“由于”，引导原因状语从句，其语气不如because强，通常为附加说明的理由，且是已知晓的原因，主句与从句没有逻辑上的因果关系。

例如：As she was not well, I went there alone.As he is a tailor, he knows what to do with this material.3. as表示“虽然……但是……”，引导让步状语从句，从句通常用倒装语序，把从句的表语、状语或动词原形放在as前面，可以用though替代。

例如：Child as he is, he knows a lot. Hard as it was raining，they went on working in the field.4. as表示“按照”、“依照”、“像”，引导方式状语从句，从句置于主句之后。

例如：You should do as the teacher tells you.The absence of air also explains why the stars do not seem to twinkle in space as they do from the earth.5. as表示“像……一样”，引导比较状语从句，对主句和从句的动作或状态加以比较，说明它们之间有相似之处，在从句中常省略与主句相同的部分。

as_和which的区别

which与as引导非限制性定语从句的异同which与as一样，都可以引导非限制性定语从句，它们既有相同之处，也有差别。

因此在实际运用中容易混淆。

它们的某些用法在高考中也会考查。

一．相同点。

两者引导非限制性定语从句时，可指代主句中的部分或整个句子的内容，在从句中做主语，宾语或表语，位于主句之后有时可互换。

The meeting was put off, as /which was exactly what we wanted.He was a doctor, as/which I knew from his manner.二．不同点1. as可指其前后主句提到的事实或情况，因此引导的非限制性从句位置比较灵活，as可以放在主句前后，也可插入主句之中；而which引导的非限制性从句只能位于主句之后。

As is known to all, fish can’t live without water.Air, as we know, is gas.2.在非限制性从句中，which后的be动词不可省；as而后的be动词可以省略。

She told me she won the match , which was a lie. The material is elastic, as (was) shown in the figure.3. which在非限制性定语从句做主语时可用各类动词做谓语；而as/which在非限制性定语从句做主语时，谓语常用连系动词，如be, seem, become等，一般不用其他行为动词。

He saw the girl, which delighted him.He didn’t say anything at the meeting , as/which seemed very strange.4. 如果主句中叙述的事情与从句所涉及的意向一致，多用as，用以对主句的意义进行补充；如果不一致，就用which She has married again, as was expected.He broke the rules again, which was unexpected.5.如表示“如同。

例如：A）As he realized, I was very useful to him.（在前）B）Air, as we know, is a gas.（在中）C）He was a foreigner, as I know from his accent.（在后）2.在which引导的定语从句中，谓语动词若是am, is, are则这些系动词不能省略；而as 后面若是这种情况，则可以省略。

例如：A）He is a teacher, as （is）clear from his manner.（is可以省略）B）He said he had never seen her before, which was not true.（was不可省略）3.当which引导的从句在意义上近乎并列关系时，可以用and this，and that代替，意思是“这件事”例如：A）He changed his mind, which（and this, and that）made me very angry.他改变了主意，这使我很生气。

B）She has married again, which（=and this, and that）was unexpected.出乎意料的是，她又结婚了。

定语从句as和which的用法

定语从句as和which的用法定语从句是我们中学时期开始就一直陪伴我们度过各种考试一种长难句。

不知道小伙伴们有没有这样的感受，那就是虽然学了这么多年的定语从句，但是在做题的过程中，碰上了定语从句依然是一筹莫展，下面先和小编一起来看一下定语从句中关系代词as和which 的区别。

1. 互换的情况：两者有时可互换。

如：I live a long way from work, as [which] you know.我住得离工作单位很远，这你是知道的。

2. 只有as的情况：以下两种情况，习惯只用as，不用which。

①在such, as, the same后引导定语从句时只能用ash。

如：I never heard such stories as he tells. 我从未听过他讲那样的故事。

It’s the same story as I heard yesterday. 这故事跟我昨天听到的一样。

This is the photo which shows my house. 这张照片拍的是我的住宅。

②当从句位于主句前面时，只用as。

如：As is known to everybody, the moon travels round t he earth once every month. 月球每月绕地球转一周，这是每个人都清楚的。

3. 值得注意的情况：以下三种情况值得注意。

①as 引导的非限制性定语从句应与主句在意义上和谐一致，但which无此限制。

比较：He went abroad, as [which] was expected. 他出国了，这是大家预料到的。

He went abroad, which was unexpected. 他出国了，这让大家感到很意外。

(不用as)②as 引导非限制性定语从句时，先行词通常不能是主句中某个具体的词，而应是整个句子、整个短语或某个短语推断出来的概念，而which 则无此限制。

as和which的异同

3）as和which的异同相同点：在非限制性定语从句中，均可替代整个主句或句中某个部分，在从句中作主语、宾语、表语。

如从句在主句之后，两者皆可用。

They failed in the exam,as /which is natural.She seems a scientist, as/which in fact she is .不同点：a 从句在主句之前用asAs we all know, his parents were killed in this war .b 表示顺从关系用as 表示转折、因果关系用whichHe has passed the exam, as we expect .He has passed the exam,which we don’t expect .Bamboo is hollow , which makes it light .c as后面多加系动词，which后面多加实义动词The earth travels around the sun , as is known to all .d Such…as/as…as /the s ame…asI have never heard such stories as he tells .The village is the same as it was four years ago .定语从句（2）二、关系副词Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace?The factory where his father works is in the west of the city.This is the reason why he was late for class.1定语从句中的关系词的选择原则：判断是用关系代词或是用关系副词，要看先行词在从句中所起的作用，当先行词是表时间、地点和原因的词时，一定要分析从句的结构，如果缺少主语和宾语时，关系词应该用which或that ，缺少时间、地点或原因状语时，才能用when、where 或why.A. This is the factory ____we worked.B. This is the factory ____we visited last year .A. I won’t forget the year ____ he studied in our school .B .I won’t forget the year ____ he spent in our school .A. The reason ____ he can’t come is that he is ill .B. The reason ____ he put forth is very important .三、介词加关系代词结构的用法1）名词+of which/whom结构，常常可以转化为whose+名词结构。

D）As is announced in today’s newspaper, we must improve our style of work.今天的报纸上说，我们必须改进工作作风。

(不用as)④当as引导非限制性定语从句作主语时，其谓语通常应是连系动词，而不宜是其他动词，而which则无此限制：如：She has married again, as[which] seemed natural. 她又结婚了，这似乎很自常。
