They found ( ) that the goddess turned out to be...

其实没什么理由,只是surprisingly,with surprise和to one's surprise用在不同的句式结构中.我举几个例子,1.This question is surprisingly easy.2.He looked at me with surprise.3.To my surprise,this question is...第三句例句to my surprise是放在句首的呀这里为什么是They found to their surprise ... 呢？to my surprise的位置可以很灵活，比如：This question, to my surprise, is so easy.This question is so easy, to my surprise.希望对你有所帮助。
