This is the photo which shows my house. 这张照片拍的是我的住宅。
(2) 引导非限制性定语从句时,有时两者可互换:
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。
(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:
① 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。
② 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)
③ 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)
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:
She has married again, as [which] seemed natural. 她又结婚了,这似乎很自常。
She has married again, which delighted us. 她又结婚了,这使我们很高兴。(不用as)
5. who与whom的用法区别。两者均只用于人,从理论上说,who 为主格,whom为宾格:
Where's the girl who sells the tickets? 卖票的女孩在哪里?
The author whom you criticized in your view has written a letter in reply. 你在评论中批评的那个作者已写了一封回信。
但实际上,除非在正式文体中,宾格关系代词 whom 往往省略不用,或用who或that代之:
The man (that, who, whom) you met just now is called Jim. 你刚遇见的那个人叫吉姆。
不过,在以下几种情况值得注意:
(1) 直接跟在介词后面作宾语时,只能用 whom,而且不能省略:
She brought with her three friends, none of whom I had ever met before. 她带了3个朋友来,我以前都没见过。
(2) 引导非限制性定语从句且作宾语时,who 和 whom均可用,但以用 whom 为佳,此时也不能省略:
This is Jack, who [whom] you haven't met before. 这是杰克,你以前没见过。
