关系代词 as与which的用法区别是什么

关系代词 aswhich的用法区别是什么
 
1. 引导限制性定语从句时,在such, as, the same后只能用as,其他情况用which。如:
I never heard such stories as he tells. 我从未听过他讲那样的故事。(不可用which)
It’s the same story as I heard from her yesterday. 这故事跟我昨天从她那儿听到的一样。(不可用which) 
2. 引导非限制性定语从句时,有时两者可互换。如:
I live a long way from work, as [which] you know. 我住得离工作单位很远,这你是知道的。
但在,在以下情况引导非限制性定语从句时,两者不可换用:
①当从句位于主句前面时,只用as。如:
As you will find out, I will never let you down. 你将会发现,我决不会让你失望。
As is known to everybody, the moon travels round the earth once every month. 月球每月绕地球转一周,这是每个人都清楚的。
as引导的非限制性定语从句应与主句在意义上和谐一致,而which则无此限制。如:
She married him, as [which] was natural. 她嫁给了他,那是自然的事。
She married him, which was disgraceful. 她嫁给了他,那是很丢人的。(不用as)
as引导非限制性定语从句时,先行词通常不能是主句中某个具体的词,而应是整个句子、整个短语或某个短语推断出来的概念,而which则无此限制。如:
I once lived in Guangzhou, which is the largest city in south China. 我曾住在广州,那是中国南方最大的城市。(不用as)
④当as引导非限制性定语从句作主语时,其谓语通常应是连系动词,而不宜是其他动词,而which则无此限制。如( www.52yufa.com)
She has married again, as [which] seemed natural. 她又结婚了,这似乎很正常。
She has married again, which delighted us. 她又结婚了,这使我们很高兴。(不用as)
