特殊的so/such...that...结果状语从句的理解？

1）The book is so written that it gives a quite wrong idea of the facts.

2）His diligence was such that he made great progress.

以上2句：

1)句中so后直接是written,不像一般都带有形容词或副词，

2)句such后也没名词。

麻烦老师解析一下这种句型该怎么样理解和用？

1）The book is so written that it gives a quite wrong idea of the facts.

2）His diligence was such that he made great progress.

1)句中so后直接是written,不像一般都带有形容词或副词

——这里，written 是形容词，一般目前时即可说明问题。so written 可能是 so well written ，也会是so badly written，需依据语境判断。本句是后者：写得太不靠谱了/非常差劲。

2)句such后也没名词。

—— such 单独用，后面没被限定语，说明是代词。
