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 。
