(3) 但在,在以下情况引导非限制性定语从句时,两者不可换用:

当从句位于主句前面时,只用 as

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,which无此限制:

He went abroad, as [which] was expected. 他出国了,这是大家预料到的。

He went abroad, which was unexpected. 他出国了,这让大家感到很意外。(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:

The river, which flows through London, is called the Thames. 这条流经伦敦的河叫泰晤士河。(不用as)
