Question

We hope the measures to control prices,_____taken by government,will succeed.
1.as 2.when3.since4after

Answer 1

填as,作代词,引导定语从句,先行词是the measures
as taken by government,由政府实施的政策
as单独引导定语从句
as单独引导定语从句时,先行词可以是一个词,也可以是一个句子或短语.例如：
(1) She is late,as is often the case.她迟到了,这是经常的事.(先行词是整个主句)
(2) To shut your eyes to facts,as many of you do,is foolish.对事实视而不见--你们好多人都是如此的愚蠢.(先行词是不定式短语)
