非限制性定语从句中which与as的用法
学法新探在非限制性定语从句中，which 与as 两者既有相通之处，又有相异之点。
如果把握不到位，区别不恰当，极易出错。
对此，笔者就非限制性定语从句中which 与as 的用法差异进行了剖析，以期同学们能够准确辨析和运用。
辨析之一：观“位置”在非限制性定语从句中，which 与as 的位置有所不同。
一般地，which 引导的非限制性定语从句不能置于句首，多位于主句之后；而as 引导的非限制性定语从句的位置则十分灵活，不仅可以置于主句之中和主句之后，而且可以置于句首，即置于主句之前。
比如，①Jake passed the driving test ，which sur-prised everybody in the office.杰克通过了驾驶考试，这使办公室里的每个人都感到惊讶。
（which 引导的非限制性定语从句置于主句之后）②Paper ，as we know ，was first made in China.众所周知，纸是中国人发明的。
（as 引导的非限制性定语从句置于主句之中）③She comes from South ，as I know from his ac-cent.我从他的口音中知道她来自南方。
（as 引导的非限制性定语从句置于主句之后）④As is known to all ，China has developed quickly these years and it has become one of the most important countries in the world.众所周知，近年来，中国的发展十分迅猛，目前已成为世界上最重要的国家之一.（as 引导的非限制性定语从句置于句首）从上述几个例子可以看出，which 与as 引导的非限制性定语从句都可以置于主句之后，两者有时可以互换。
但需要注意的是，当在主句之后的非限制性定语从句为否定句或带有否定意味时，只能用which 引导，不能用as 。

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.
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,T aiwan 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。
