so much that结构剖析

I found it changed so much that I couldnt hardly recognized it.

it 是宾语，changed 是宾补，so much that 是引导一个状语从句，修饰这个宾补 changed，是如此吗？

I found it changed so muchthat I couldnt hardly recognized it.

1. 原句有两处错误，见红色部分。应改为：

I found it changed so muchthat I could hardly recognize it.

2. changed 是过去分词，作宾补，不是谓语动词。

3. 主句含有程度副词so，表示changed 达到了某种程度，因此，that 从句是“结果状语从句”。
