上古汉语与现代汉语发音迥异,可为什么用现代汉语朗读上古的诗歌依旧会合辙押韵呢?

这么说吧,是完全不同的.
虽然二者都有语气词的词性,但表达的意义不一样.
也,表示的是肯定判断、疑问、句中表停顿、另外一种是副词
矣,表感叹、请求命令.另外一种之相当于现在的“了”的作用

语法学家王力先生认为上古汉语只有并列式的复合动词（及物动词+及物动词、不及物动词+不及物动词）,这一语法制约是不允许动补式（及物动词+不及物动词）这样的组合的.而太田成夫（1958）和梅祖麟（1991）则认为,由于中古时期起词施受关系的中立化,汉语动补式始于中古.

上古汉语里的疑问词分为疑问代词和疑问语气词,
疑问代词有谁、孰、何等,疑问语气词有乎、诸等.
