I wandered around the library, fascinating to find one treasure after another.
这句话中， fascinating 为何要改为facinated？
I wandered around the library, fascinating to find one treasure after another.
改为正确：I wandered around the library,fascinatedto find one treasure after another.
分析：填“fascinating”为错误，由于分词的逻辑主语为句子主语I，是被动逻辑主谓关系，不是主动逻辑主谓关系。所以要填“过去分词fascinated”
fascinate vt. 使着迷; 使神魂颠倒; 蛊惑;
A fascinate B 意思为“A使B着迷”（A是动作实行者，B是动作承受者）

假如把第2种结构变为非谓语动词，就是去掉主语A和助动词be直接保留过去分词。
备注：假如分词被形容词化之后，失去原有动作含义，相当1个形容词。
