As has been announced , we shall have our final exams next month.
As在句子中有什么语法，为什么不能用That或 IT 代替？？

Answer 1

正如 怎么怎么样吧 具体不是很清楚 我老师就是直接当固定来叫的 as is known to us all 正如我们知道的

As（正如） has been announced，we shall have our exams next week. (插入语结构)
==It has been announced that we shall have our exams next week. （主语从句）
===That we shall have our exams next week has been announced (by the school).（主语从句）
===we shall have our exams next week,which has been announced (by the school).（定语从句）
=== What has been announced (by the school) is that we shall have our exams next week. （表语从句） 前人的回答 ，貌似 也没讲清楚 倒装不是的 倒装as 表虽然的

Answer 2

as在这里是当的意思，不能用it 和that 代替，他们都没那个意思

追问

As 在这里不是正如的意思么？

追答

正如就是当的意思撒， it 和that 没这个意思

Answer 3

as引导非限定性定语从句，代替后面的句子。可翻译成：正如......的
