As 和 Which 引导的非限制性定语从句的区别
As 和Which 引导的非限制性定语从句的区别山西省夏县中学外语组翟运学先让我们看一道高考试题：2004 年江苏英语高考题第33 小题＿＿＿＿＿＿is often the case, we have worked out the production plan.Ａ．Which Ｂ．When Ｃ．What Ｄ．As我们知道，as 可单独引导非限制性定语从句，作用相当于which ，那么在非限性定语从句中究竟用as 引导还是用which 引导呢？现归纳如下：１．从as ／which 在句子中位置来区分as 和which 都可以指代主句中的一部分或整个句子的内容，有时可以互换，但as 引导的非限制性定语从句位置比较灵活，可以位于主句前面，中间或后面，一般用逗号与主句隔开，而which 所引导的非限制性定语从句只能放在主句之后。
例如：（１）As is expected, our school team won the football match.（２）Our team lost the game, as/ which was reported in the newspaper.（３）Mother was terrified, as/which I could see from her eyes.２．从as ／which 在句子中特定含义来区分as 在引导非限性定语从句中有时有“正如”、“正像”之意，而which 则无此意。
常用句型有：As we all know, as is known to all, as everybody can see, as is expected 等。
如：（１）As we all know, paper was first made in China.（２）The earth runs around the sun, as is known by everyone.（３）As anybody can see, the elephant is like a snake. 或：The elephant, as anybody can see, is like a snake. 或：The elephant is like a snake, as anybody can see.３．从主从句意义匹配要求来区分as 引导的从句在意义上不能与主句相抵触，而which 则不受此限制。

as_which引导定语从句的区别
众所周知，which与as都可以引导定语从句，但它们有许多用法上的区别，现就此简要分析如下：一、which与as引导非限制性定语从句的区别：1．Which只能放在主句后面，而as引导的从句位置相对较灵活，可在前，可在中，也可在后。
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。
而as主要起与上下文连接的作用，表达说话人的看法、观点，并指出主句内容的出处或根据等，例如：C）Einstein, as we know, is a famous scientist.爱因斯坦，众所周知，是位伟大的科学家。
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。
as which 的区别
1、as与which的用法区别：(1)引导限制性定语从句时，在such,as,thesame后只能用as，其他情况用which：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)引导非限制性定语从句时，有时两者可互换：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。
(3)但在，在以下情况引导非限制性定语从句时，两者不可换用：①当从句位于主句前面时，只用as：如：As is known to everybody, the moon travels round the earth once every month. 月球每月绕地球转一周，这是每个人都清楚的。
②as引导的非限制性定语从句应与主句在意义上和谐一致，which无此限制：如：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)③as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：如：The river, which flows through London, is called the Thames. 这条流经伦敦的河叫泰晤士河。
(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。
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。

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。
