-----in her music,the young girl knocked over a pile of book

因为 分词短语作状语的时候,逻辑主语就是句子的主语 这里absorb 的逻辑主语就是 the young girl某人全神贯注地干什么 是 sb be absorbed in（ doing) sth这样一看就该知道应该是过去分词Deeply absorbed in her music = As she was deeply absorbed in music (原因状语从句）请及时采纳,不懂继续问( 天天在线 ）(*^__^*) 祝学习进步! 谢谢! 再问： 如果句子这样，Having been deeply absorbed in her music,the young girl knocked over a pile of book, 还原就是the young girl having been deeply absorbed in her music，····，这里有主谓宾，不缺成分，但是用逗号，这样可以？ 再答： 不可以！！这不是还原，你这有点象独立主格结构了，分词的逻辑主语和句子的主语一致的话，不要这样 可以用原因从句 As she was deeply absorbed in her music, the young girl。。。。
