Deeply moved by the story,the girl couldn't help crying

Deeply moved by the story,the girl couldn't help crying.此句中是过分短语作原因状语.因为the girl 是受到感动,表示被动,故要用过分(表被动).Having been refused,the boy felt disappointed.此句中的原状仍然是...为什么第一句不能是having been done?因为moved这个动作几乎与谓动的动作同时发生，故不能用having been done。 如用having been done，则说明女孩感动的一会儿之后才忍不住哭出来，这有点不合情理。
