什么是非限定性定语从句？

Answer 1

能够引导非限制性定语从句的连接词有：which，who，whom，where，when，as等，其中最常见的就是which和as。

as, which 引导的非限定性定语从句由as,which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。

扩展资料：

as引出非限定性定语从句时，代替整个主句，对其进行说明但通常用于像as we all know, as it is known, as is known to all, as it is, as is said above, as always mentioned above, as is usual, as is often the case, as is reported in the newspaper等句式中。

as在非限定性定语从句中作主语、宾语，且引出的从句位置比较灵活，可位于句首或句末，也可置于主句中间。通常均由逗号将其与主句隔开。as有“正如……， 就像……”之意。
