_____in her music,the young girl knocked over a pile of book,
问题描述：
_____in her music,the young girl knocked over a pile of book,
A.Deeply absorbed B.Having deeply absorbed.
为什么是A.我们老师说B要换成Having been deeply absorbed,有逗号
前面不是非谓语吗,为什么还要be呢
答
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）

(*^__^*) 祝学习进步! 谢谢!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 girlhaving 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？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....
