Question

英语语法分析
A student of music needs as long and as arduous a training to become a performer as a medical student needs to become a doctor.
请对该句话进行语法句型分析,尤其是as在此的用法

Answer 1

一个音乐专业的学生要成为一个演奏家,和一个医学专业的学生要成为一个医生要付出同样多的时间和努力去训练
主干：a student of music needs a training to become a preformer
什么样的学生呢：of music 音乐专业的
什么样的训练呢：as long (a training)and as arduous a training 长时间又辛勤的
这是两个as...as 连用,和后边的as a medical student needs (a training)to become a doctor 连起来,表示音乐专业的学生付出的努力和医学专业的学生付出的努力一样多.
