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 。
as与which引导定语从句的用法辨析
as与which引导定语从句的用法辨析一、as和which都能引导的定语从句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。
二、只能用which引导的定语从句1. 在限定性定语从句中。
2. “介词+关系代词”引导定语从句时，只能用which。
3. 当后置的非限定性定语从句是否定结构时，只能用which引导。
三、只能用as引导的非限定性定语从句1. 置于句首时，非限定性定语从句只能用as引导。
2. 在the same...as 结构中，意思是“像……那样的”。
3. 在as...as结构中，意思是“像……那样的”。
as作从属连词用时，可以引导五种状语从句。
现归纳如下：1. as表示“当……的时候”，引导时间状语从句，多强调主句和从句中的动作或状态同时发生，从句可放在主句前，也可放在主句后。
例如：As I waited at the stop，I heard a big noise.She rose up as he entered.2. as表示“因为”、“由于”，引导原因状语从句，其语气不如because强，通常为附加说明的理由，且是已知晓的原因，主句与从句没有逻辑上的因果关系。
例如：As she was not well, I went there alone.As he is a tailor, he knows what to do with this material.3. as表示“虽然……但是……”，引导让步状语从句，从句通常用倒装语序，把从句的表语、状语或动词原形放在as前面，可以用though替代。
例如：Child as he is, he knows a lot. Hard as it was raining，they went on working in the field.4. as表示“按照”、“依照”、“像”，引导方式状语从句，从句置于主句之后。
例如：You should do as the teacher tells you.The absence of air also explains why the stars do not seem to twinkle in space as they do from the earth.5. as表示“像……一样”，引导比较状语从句，对主句和从句的动作或状态加以比较，说明它们之间有相似之处，在从句中常省略与主句相同的部分。
