(1)引导限定性定语从句
在限定性定语从句中,as多与such, so/as或the same连用,构成“such…as”“so/as…as”或“the same…as”结构。
如:Such people as were recommended by him were reliable.(他所推荐的人是可靠的。)In the city, I saw so grand a National Day celebration as I ever dreamt of.(在这个城市,我看到了梦想中盛大的国庆盛典。)She told me the same story as she had told you.(她给我讲的这个故事和给你讲过的一样。)
(2)引导非限定性定语从句
在非限定性定语从句中,as作为关系代词代替整个主句。as引导的从句位置较灵活,可以位于主句前面、中间或后面,一般用逗号与主句隔开,通常译为“正如/像……一样”。
as后若为“is/was +过去分词”构成的被动语态,is或was可省掉。但若as后接“is/was+现在分词”, is或was不可省。
如:The material is elastic, as (is) shown in the figure.(如图所示,这种材料富有弹性。)Another recession is setting in, as is already occuring, for instance, with the car industry.(又一次衰退正在到来,比如,在汽车工业中已经出现了这种情况。)
As (was) expected, he was admitted to the university.(正如所预料的那样,他被大学录取了。)
