as it is well known 和 as is well known的句子结构区别?

as it is well known 因为它很知名,as 引导原因状语从句
as is well known, 众所周知,/正像大家都知道的那样,as 引导非限制性定语从句,在从句总做主语,代替逗号后的整个句子。 意思是“正如;正像”
希望能帮到你!

都作非限制性定语从句,只是as 在第一句中作表语;在第二句作主语。

缺乏上下文,不好断定.
as it is well known,应当是引导原因状语从句,且正常语序:因为/由于众所周知的.
as is well known,as 是关系代词,指代后面的一个句子或事实.
e.g.As is well known,the Earth goes around the Sun.
= The Earth goes around the Sun,as/ which is well known.
