As is shown in the picture ,there is a cobweb-like structure with separate compartments packed in it.（as=后面的句子？还有什么词或词组像它这样的用法？）

Taiwan is, as you know, an inseparable part of China.(as＝Taiwan is an inseparable part of China.)是吗？as you know是插入语吗？

【答】红色部分的两个从句，都是as 引导的非限制性定语从句。

as 引导非限制性定语从句，其先行词是整个主句，as 在从句中作成分（主语或宾语）。而引导状语从句时，as 是不作成分的。

as 可以引导非限制性定语从句，先行词就是整个主句，它在定语从句中作主语、宾语。它引导的从句可以位于主句前，也可以位于主句后，还可以位于主句中间。

As everybody knows, Shakespeare was a great English writer.众所周知，莎士比亚是伟大的英国作家。（从句在主句之前，as作从句的宾语）

Tom is a brave boy, as is described in the report.汤姆是一个勇敢的男孩，这正如在报道中描述的那样。（从句在主句之后，as作从句的主语）

The project, as we had expected, got along well.正如我们所预料的那样，工程进展顺利。（从句在主句中间，as作从句的宾语）

as I can remember 正如我所记得的
