区别在定语从句中，as与that在用法上有什么区别

Question

如题所述

Answer 1

As可以担当句子成分，As you know(as作 know宾语), 而that只是一个连词，

As还有正如……（及前面所提到的事情）的意思，

如:

as you know.一般用于非限定性定语从句,'正如大家知道", 可以放在句首.

that作连接代词，起引导作用,代替先行词在从句中作成分，

You haven't payed me back the money that you borrowed from me.

that 代替MONEY,作borrow 的宾语

而As可以表示前面整个句子的意思。

As  is known to all , the Dragon Boat Day falls on lunar clendar on May , the 5th.

as 代替后边整个句子
