as引导的定语从句

Question

Here is so easy a question as everybody can answer.书上说，as在从句中做结果状语，应该是原因状语吧

Answer 1

as 在定语从句中是关系代词，可做句子成分。但在上述两个句子中，as只是在引导定语从句而已，不作句子成分。

as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思
(1) As is known to all, China is a developing country.
(2) He is from the south, as we can see from his accent.
(3) John, as you know, is a famous writer.
(4) He has been to Paris more than several times, which I don’t believe.

As 的用法例
1. the same… as；such…as 中的as 是一种固定结构, 和……一样……。
I have got into the same trouble as he (has).
例2. as可引导非限制性从句，常带有'正如'。
As we know, smoking is harmful to one's health.
As is known, smoking is harmful to one's health.
As是关系代词。例1中的as作know的宾语；
例2中，它充当从句的主语，谓语动词know要用被动式。

Answer 2

as是关系代词，指代先行词question 在从句中作 answer 的宾语。
定义：先行词受到 so, such .the same 修饰时，关系代词用as.
