非限定性定语从句区别
编辑
1、as引导的定语从句可以放在句首、句中和句尾，which引导的定语从句可置于句中或句尾。
2、关系代词as在限定性定语从句中后跟“be动词+过去分词”的被动语态时，be动词可省略。
3、 as有时也可用作关系代词 。若as在从句中作主语，其引导的句子可以放在句首或句中。但which引导的非限制性定语从句只能放句中。
4、as有正如…一样、按照、正像、因为的意思，所以常用于肯定句，而which则用于肯定，否定都可以。
5、在固定结构中使用as 例如：the same … as 、as … as。
例句：
1 Dorothy was always speaking highly of her role in the play, which , of course, made the others unhappy.（从句部分的意思为：这当然使别人不高兴；而不能译为正如使别人不高兴。故用which。）
2 Chongqing is not the same city as we have seen in other places.
重庆和我们在其它地方看过的城市不一样。
