which与as在定语从句中的不同用法

which与as在定语从句中的不同用法

which与as在定语从句中的不同用法下面是小编整理的一些关于which与as在定语从句中的用法,希望帮助大家区分这两个单词。

提高英语水平。

which与as在定语从句中的不同用法一、which与as用法相同点1. as和which都能引导定语从句,并都可以在定语从句中做主语或宾语,代表前面整个句子。

例 1 He married her, as / which was natural. 他跟她结婚了,这是很自然的事。

例 2 He is honest, as we can see. 他很诚实,这一点我们看得出来。

(表示人们从日常主观常识, 经验对某一事情的看法、评价,用as为妥。

)2. 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。

例 3 The number of senior high school students is increasing, as is mentioned above. (as引导非限定性定语从句,意思是“正如”。

此时也可以换用which引导,但意思有别,意思是:“这一点上面提到了”。

)二、which与as用法不同点(一)语义上的区别as作为关系代词仍多少保留“理由”“比较” “方式” “等同”等意义,而which没有这些意义。

因此,由as引导的定语从句通常在意义上不可与主句相悖,而且一般是肯定的,对主句意义起相辅作用,表示“正如”等意义;而which引导从句则不受此限制。

例 4 Mother treats me just like a baby,which I can’t bear. 妈妈对我就像小孩,我真受不了。

例 5 She has married again,which was unexpected. 她又结婚了,这是大家没有预料到的。

上面两句中的which都不宜用as。

但当否定的定语从句作正面理解,对主句起相辅作用而不是与其相悖时,仍可用as。

【初中英语】定语从句as和which的用法(1)

定语从句1.非限定性定语从句——用逗号隔开作用:提供附加而非必要的信息,只是对先行词作进一步的解释、补充或者说明。

若去掉此定语从句,整个主句的意义一样很明确,不会引起误解和歧义。

eg.Beijing,which is the capital of China,has developed into a international city.如果定语从句修饰一个专有名词,我们一般要用逗号,也就是说要用非限制性定语从句。

因为专有名词本身的含义就很完整,不需要限制,用定语从句知识对它进行补充说明。

2.As的用法(1)as在引导限定性定语从句时,只是在一些固定的结构中,即只能用在such,the same, as ,so 的后面。

eg.he is not the same as we knew.(2)as引导非限定性定语从句可位于句首,而which不能这么用。

eg.As is known, the whale is not fish but a mammal.(as指的是 the whale is not a fish but a mammal.)总所周知,鲸不是鱼类,而是哺乳类动物。

(3)as和which都可以引导非限定性定语从句,代替前面的整个句子。

eg.he married her, as/which was natural.但因为as引导的定语从句有“正好...”,“就像...”,“由...而知”的含义。

所以,当主句和从句内容上一致时,或者说从句内容是顺着主句意思说下来时,用as。

若主句和从句内容上下不一致时,或从句内容对主句的内容起反对、排斥、否定等消极作用时,多用which。

eg. She has married again, as was expected.She has married again, which was unexpected.。

as与which的区别


注意区别:
the same...as 相同物体 the same...that 同一物体 She wore the same dress as her younger sister wore. She wore the same dress that she wore at Mary's wedding.
Kate was late for school , as语义与主句一致, which无此限制
She has married again, which/as was expected. She has married again, which was unexpected.
一、as和which引导非限定性定语从句的区别
1、从句位置不同 as : 句首、中、后 which :主句或先行词之后,不位于句首
1) She told me she won the match , which was a lie. 2)As is known to all, fish can’t live without water. 3)Air, as we know, is gas. 4)He was a doctor, as I knew from his manner.
as 有正如….那样的意思。
