It was of too fine a quality.中too fine a quality是什么英语语法点啊？

它的质地太细了。
It's of too fine a quality相当于倒装the quality is too fine.
too 表示“太。。。了”，有点过头了，所以一般有too都带一点点贬义。
of表示物体的属性，“有着。。。”
She is of too fine a girl=The girl is too fine.
这女孩太好了（too表示好得有点过头了，后面接不好的事情。。。如：容易被人利用。。。等等）
例句：
" But the arson took a look and shook his head;he wouldn't take it for it was of too fine a quality.
石匠看了看，摇着头，嫌它石质太细，也不采用。
