as is well known = as is known to all 众所周知
as we had expected 正如我们所预料的那样
as often happens 正如经常发生的那样
as has been said before 如上所述
as is mentioned above 正如上面提到的
4. “介词+关系代词”结构引导非限制性定语从句，一般有以下几种结构：(1)名词+介词+关系代词：
They live in a house, the door of which faces south.4. “介词+关系代词”引导非限制性定语从句的几种结构(2)代词+介词+关系代词：
There are four students in the classroom, all of whom are working hard.
(3)数词+介词+关系代词：
Last Sunday I bought a book from the bookstore, three of which were English novels.(4)形容词比较级/最高级+介词+关系代词：
