WangFang asked:"When did you finish reading it,Lily?"改为间接引语

WangFang asked Lily when I finished reading it.
when 可以用于一般过去时,但不能和完成时搭配
不明白的再问哟,请及时采纳,多谢!
再问： 谢谢你的回答 I应该要改为she吧？还有，那些疑问副词都不和完成时连用吗？
再答： 对 WangFang asked Lily when she finished reading it.
再问： 好的 我明白了 那再帮忙解析：She asked me:"What's wrong with you?"为什么要改成She asked me what was wrong with me.
再答： 主句 asked 用的是一般过去时，从句也用过去时，所以将 is 改为 was
再问： 但改完的结构不是应为特殊疑问词+陈述句语序吗？
再答： what 相当于主语的位置 如： He asked who was on duty
