as与 which非限制性定语从句辨析跟踪练习题
as与which引导非限定性定语从句
as与which引导非限定性定语从句用法首先，as和which都可以表示主句在意义上的连贯，在从句中作主语，或用作及物动词的宾语，如：He married her，which was natural．I was very useful to him，as he realized．1．as既可以指前面提到过的事实或情况，因此as可以放在句首、句末，也可以插入主句中，而which指前面提到的事实或情况，一般放在主句之后（有时也可用as），如：As our teacher points out，that book is of benefit to everyone．Heat is a form of energy，as is known to all of us．This machine，as might be expected，has stopped operating．2．as含有正如、按照、正像之意，as一般用在肯定句中，而which则多用于含否定意义的句子中，如：He failed in the exam again，as was expected．He failed in the exam again，which was unexpected．3．当定语从句所修饰的主句内容是谓语动词的对象时，常用as，如：Jack was admitted into the university，as we had expected．4．下列固定结构，一般不能用which，如：as has been said before 如前所述as often happens 正像经常发生的那样as is well known 众所周知as will be shown in Fig 3 将如图3所示as we know 正如我们知道的那样＂as may be imagined 这可以想象得出来as we all can see 正如我们大家看到的那样5．当关系代词代表主句引起的结果，又做主谓宾补（svoc）结构中的主语时，多用which，如：He saw the girl，which delighted him．He didn＇t pass the exam，which made his mother angry．6．在从句中作介词宾语时，用which，如：We didn＇t go to the film，instead of which we went to the theatre．7．在从句中作定语时，常用which，如：I told her to see a doctor，which advice she took．8．在从句中代表主句中的谓语的整个概念时，常用which，如：He can write a letter in English，which I can not．9．指代主句中一个名词时，多用which，如：I gave him an interesting book，which he started to read at once．10．代替主句中的形容词时，常用which，如：He thought me impatient，which he himself was．练习（判断正误）1．Her performance was wonderful，which we had expected．2．He told us a joke，which made all of us laugh．3．As is well known to us all that the earth is round．4．Metal will bear beating with a hammer，as a stone will not．5．He was emigrated（移居）in 1948，at which time there was much hardship and unrest．6．Mum always treats me just like a baby，as I can＇t bear．7．Lincoln was shot in a theatre，which was described in this book．8．His children asked him to go for a row with them in the afternoon，which he promised．9．This book，as is imagined，is very good．10．Dorothy was always speaking highly of her role in the play，which，of course，made the others unhappy．定语从句练习1.The place _______interested me most was the Children's Palace.A.

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 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. thatB. whichC. itD. 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。

初中英语 非限制性定语从句练习题(含答案)
限制性定语从句作用：限制性定语从句是先行词在意义上不可缺少的定语，若去掉，所修饰主句的内容就不完整或失去意义。
这种从句和主句的关系十分密切，写时不可用逗号分开。
例：She has found the nacklace（that）she lost two weeks ago, 她找到她那条丢失两周的项链。
非限制性定语从句作用：非限定性定语从句的作用是对所修饰的成分作进一步说明注（：通常和主句间用逗号隔开，不受主句句子结构的影响，将从句拿掉后其他部分仍可成立）语法：1. that不能用于引导非限制性定语从句2. 有时as也可用作关系代词3. 在非限定性定语从句中，用who, whom代表人，用which代表事物。
4.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。
例1：Charles Smith, who was my former teacher, retired last year.查理·史密斯去年退休了，他曾经是我的老师。
例2：My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。
例3：This novel, which I have read three times, is very touching.这本小说很动人，我已经读了三遍。
5.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。

【高中英语】英语语法：as, which非限定性定语从句
【高中英语】英语语法：as, which非限定性定语从句【高中英语】英语语法：as,which非限定性定语从句由as和which引导的非限制性定语从句。
As和which可以代替整个主语句，相当于and this and that。
通常放在句首，也就是在句子中。
asweknow,smokingisharmfultoone'shealth.地球对我们来说非常重要。
典型例题1）艾丽丝收到了来自赫伯斯的激励，这让她感到惊讶。
a.itb.thatc.whichd.he答案C.这是一个非限制性条款。
你不能用它来修改它，但它和他都把后一句话变成了一个句子。
两个独立的句子不能单独用逗号连接。
此外，选择这个句子是没有意义的。
2)theweatherturnedouttobeverygood,___wasmorethanwecouldexpect.a、什么b、哪个c、那d、它答案b。
which可代替句子，用于非限定性定语从句，而what不可。
that不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。
3）昨天我受到了严厉的惩罚，防止了我去公园。
a.thatb.whichc.asd.it答案Bas和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。
但不同之处主要有两点：（1） as引导的定语从句可以放在句首，但不能放在句首。
(2)as代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词;若为行为动词，则从句中的关系代词只能用which.。
在这个问题中，因为prevent是一个动作动词，正确的选择应该是B。
as的用法例1与……相同；就这样。
这是一个固定的结构，就像。
ihavegotintothesametroubleashe(has).例2 As可能导致非限制性条款，通常带有“As”。
asweknow,smokingisharmfultoone'shealth.asisknow，烟雾缭绕。
非限制性定语从句讲解及练习
非限制性定语从句\作用：非限制性定语从句只是先行词的附加说明，如果去掉从句，意义仍然完整。
先行词：关系代词：as，which，who，whom，whose等，作定语从句的主语、宾语、表语及定语。
关系副词有when，where等，作定语从句的状语。
关系代词和关系副词在定语从句中一般不能省。
最大的特点：用逗号“，”与主句隔开。
非限制性定语从句举例：His mother, who loves him very much, is strict with him. China, which was founded in 1949, is becoming more and more powerful.什么时候用非限制性定语从句？.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
非限制性定语从句中的五个不能一、非限制性定语从句通常不能用that引导。
如：1. I like the book, which was bought yesterday. 我喜欢这本书，这是昨天买的。
2. I like the book which / that was bought yesterday. 我喜欢昨天买的那本书。
二、非限制性定语从句不能用why引导。
要用for which代替why。
如：1. I had told them the reason, for which I didn't attend the meeting. 我已经把理由告诉了他们，为此我没有去开会。

同样，例4和例5中的“which”也是关系代词，引导非限制性定语从句，“which” 的先行项也是整个主句（划线部分）。
例6中的“which”所指代的先行项是“that”引导的整个宾语从句（划线部分）。
因此，一些学生常问此时的“as”和“which” 是否可以互换使用，在实际使用中应如何选择。
as和which在引导非限制性定语从句中时，其用法有三点相同和四点不同之处。
一、相同点：1. “Which”和“as” 都可在SVC（主语+系动词+表语）或SV（主语+谓语）结构的非限制性定语从句中作主语，此时两者可互换使用。
例如：He said he had lost the book, which/as was true.He failed in the examination, which/as seemed natural.The ships were frozen in, which/as often happens in this region.2. 在SVC结构的非限制性定语从句中，which和as 作表语时可互换使用。
限制性非限制性定语从句详解练习(附标准答案).doc
定语从句用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫作定语从句。
一．词引导的定语从句1. 关系代词用来指代先行词是人或物的名词或代词句子成分用于限制从句或非限制性从句只用于限制性从句代替人代替物代替人或物主语Who which that主语Whom which that宾语Whose(=of whom) whose(=of which)例1：This is the detective who came from London.例2：The book which I am reading is written by Tomas Hardy.例3：The desk whose leg is broken is very old.例4：This is the room that Shakespeare was born in.2．关系代词的用法(1) 如果先行词是all, much, anything, something, nothing, everything,little, none 等不定代词，关系代词一般只用that ，不用which。
例如：All the people that are present burst into tears.(2) 如果先等词被形容词最高级以及first, last, any, only, few, much, no, some, very 等词修饰，关系代词常用that, 不用which, who ，或whom。
例如：(3) 非限制性定语从句中，不能用关系代词that, 作宾语用的关系代词也不能省略。
例如：There are about seven million people taking part in the election, mostof whom、are well educated.(4) which 还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。

2.Creating an atmosphere ________ employees feel part of a team is a big challenge.A. asB. whoseC. in whichD. at which【答案】C【解析】句意：创造一种雇员感觉是其中一员的氛围是一个大的挑战。
这是一个定语从句，in the atmosphere “在氛围中”是一个固定搭配。
此处也可以是where. 分析句子结构和结合四个选项，知道在这里面所需要填的是连词。
然后空格之前是一个名词，这种情况首先考虑的是定语从句。
然后分析之后的句子是具备完整的结构（有了主语employees和宾语part of a team）所以这应该是需要一个充当状语的连词，如where, when , why. 由于when用于时间，Why用于原因，剩下的使用where，所以这里填where。
但是答案没有这个选项，根据搭配介词+which="where" 及in atmosphere 是固定搭配，故选C。
【点睛】考查定语从句，本题涉及”in+关系代词which“引导的限制性定语从句。
