studies have yet to answer the question of how well they are teaching it.

问题描述:

studies have yet to answer the question of how well they are teaching it.
怎么翻译,yet怎么翻译,为什么不放在have前,yet是副词啊,还有how well是一起做的成分吗,做的什么成分,怎么翻译呢?

研究已经回答了他们教它教的有多好的问题
study作名词,是研究的意思
yet表示“已经”是副词,但此处是现在完成时,have为助动词,所以要将yet放在have后面
how well是"多好“的意思,一起作they are teaching it的状语
