as引导的非限制性定语从句是什么?

Answer 1

在as引导的非限制性定语从句中，连接代词as在句子中可以作主语，宾语或表语等，可以指人或物。

其在定语从句中的位置比较灵活，即可以在句子前面，也可以在句子中间或句子末尾。

常用的结构有：

As we all known

As is well known to

As is often the case

As is said/mentioned above

As has been said before

As I told you before

As is evident

As often happens

As can be seen

As is/was expected

As we expect

As I can remember

注意：

As通常只指整个句子的内容，不表示部分内容。

As引导的非限制性定语从句通常指“事先可以预料的，料想到的”，表示“好”的方面。

As引导限制性定语从句时，常构成the same…as…；such…as…；so/as…as…等结构。在从句中既可以指人，物，也可以指整个句子。
