非限制性定语从句which 篇1
which引导的非限制性定语从句既可以指整个句子内容,也可以指句子的部分内容(如单词或词组等),在句子中可以作主语、宾语(动词或介词的)、定语等。注意它在句子中的位置:只能放在主句后,不能放在主句前。表达的内容是"不好的"、"事先没有预料到的"等时,常用which,只指物。

非限制性定语从句which 篇2
我们知道,as和which作为关系代词都可以用来引导非限制性定语从句,指代整个主句所表
达的内容,在从句中作主语或宾语,但它们在用法上有区别,这一点许多学生往往搞不清楚。现就它们引导非限制性定语从句的用法简述如下:
一、相同之处
当从句位于主句之后,引导词指代整个主句所表达的全部意义时,as和which可以互换。如:
The elephant is like a snake,as/which everybody can see.
大家都看得出,这头大象像条蛇。
A big earthquake occurred there last night,as/which was reported on TV.
据电视报道,昨夜那里发生了大地震。
She is from Shanghai,as/which I know from her accent.
她来自上海,那是我从她的口音知道的。
二、不同之处
1、as引导非限制性定语从句时,位置比较灵活,可位于主句之前,也可位于主句之中或之后;而which引导非限制定语从句只能位于主句之后,不能位于主句之前。如:
_______ is known to everybody,the moon travels round the earth.
A.It B.As C.That D.Which
答案:B
_______ is mentioned above,the number of the students in senior high schools is increasing.
A.Which B.As C.That D.It
答案:B
Air,as we know,is a gas.众所周知,空气是一种气体。
He is very careful,as his work shows.
他的工作表现表明他非常谨慎。
as引导非限制性定语从句常有“如同......那样”的含义,因此在一些固定结构中,如:
as we know;as is known to all(众所周知)
as we all can see(正如我们大家都能看到的那样)
as has been said before/above(正如前面所述)
as has been pointed out(正如所指出的那样)
as might be imagined(可以想象得到)
as might be expected(正如所预料的那样)
as is often the case(情况通常是这样)
以上种种固定搭配,一般不能用which代替as。
2、搭配上,在由the same或such所修饰的名词后通常用as作关系代词引出非限制性定语从句。如:
I have got into the same trouble as he (has).
我遇到了与他一样的麻烦。
I've never heard of such a moving story as he is telling.
限制性从句我从未听过像他讲得那么有趣的故事。
3、which引导的从句在意义上相当于一个并列句,可以用and this代替,意思是“这件事”;as引导的'从句主要起连接上下文的作用,表达说话人的观点、看法,并指出主句内容的根据或出处等。如:
He sold his new car,which surprised me.
=He sold his new car,and this serprised me.
Einstein,as we know,is a famous scientist.
我们都知道,爱因斯坦是一位著名的科学家。
As is known to all,Taiwan is part of China.
众所周知,台湾是中国的一部分。
4、当which在从句中指代的是先行词本身而不是主句时,不可用as代替which。如:
The peach tree,which I planted last year,has not borne any fruit.
这棵桃树是我去年种下的,还没有结出任何果实。
The book,which I bought yesterday,is very instructive.
我昨天买的这本书很有教育意义。
5、在从句中作主语时,which既可作系动词be的主语,也可作实义动词的主语,而as只可作系动词be的主语。如:
He married her,which was nature.(可用as代替which)
他和她结婚了,这是很自然的事。
She met the boy,which delighted her.(不可用as代替which)
她见到了那个男孩,这使得她很高兴。
He failed in the exam again,which made his parents very angry.
他考试有不及格了,这是他父母很生气。
6、as引导的从句在意义上不可与主语相悖,而which引导的从句则不受此限制。
Mum treats me like a baby,which I can't bear.
妈妈把我当小孩看待,这是我不能忍受的。
