分析句子
First of all,students are very young and,compared with their teachers,are less knowledgeable both in theory and practice on a suject.
谁能分析下第二句students are very young and中的and是什么用法,后面什么也不接,这么突兀的在这里.这个句子本身应该是没有错的,是书上的.

Answer 1

这句话是对的.compared with their teachers做插入语
标点也没有错.
这样看就清楚了吧 Compared with their teachers,students are very young and are less knowledgeable both in theory and practice on a suject.
