下面句子中的as做什么成分?
(1)It was such a loud noise as to wake everybody in the house.(2)Her illness was not such as to cause anxiety
(3) Would you be so kind as to do me a favour?
as to do 引导的是某种结果.想知道为什么要在to do 前加个as,as 在这里是关系代词吗?
难道as在这里就没有什么作用吗?只是以固定的短语来看待.
答
so\such as to 是固定词组,意为如此...以至于...
so\such修饰一种状态,as to接这种状态引起的结果..
