It's known to us that还是it's known tous

Question

如题所述

Answer 1

It Is known to us 和as is known to us 区别:
1、It Is known to us that /to do是独立句，其中it 是形式主语，真正主语是后面that 从句或to do动词不定式，举例如下；
It Is known to us that the earth revolves around the sun.
众所周知，地球围绕太阳公转。
2、as is known to us 是从句，非限定定语从句前置形成，举例如下；
the earth revolves around the sun，which Is known to us.
地球围绕太阳公转，这个我们都知道。
当非限定定语从句which Is known to us前置到句首，which必须换成as，转换成as is known to us，所以形成；
as is known to us， the earth revolves around the sun.
3、as is known to us不能作为独立句，后面必须接主句；
As is known to us, the chinese are a industrious and gallant nation.
众所周知，中国人民是勤劳勇敢的民族。
