LZM上面的一道题 看不明白结构呢

 Rembrandt so treasured his collection of Islamic portraits that when forced to sell them in order to raise money,he first made copies of more than twenty.

A he first made copies of more than twenty

B first he made copies of more than twenty

C more than twenty were copied

D copies of more than twenty were made

E he copies more than twenty of them first

看不明白结构。请教！除了LZM的解释方法还有别的方法解释吗？

R ｓｏ．．．　ｔｈａｔ...的结构啊

那谓语在哪里啊?

不知道怎么回事看不出来啊  Rembrandt 是个人名把？so that 没有系动词啊

so...that结构并不一定是 sth is so adj that...

R so+v that he +v

就是so+句子,that+句子
