问题描述：
Each of the students,working hard at his or her lessons,hopes to go to college 在这句话中为什么要
Each of the students,working hard at his or her lessons,hopes to go to college在这句话中为什么要使用两个逗号呀?把两个逗号去掉就这样:Each of the students working hard at his or her lessons hopes to go to college行不?
答
中间的是插入语 补充说明的 主语是student谓语是hopes to最好变成同位于从句加that那句working不是明显的伴随状语到底是插入语还是伴随状语呀？？把那句话的两个逗号去掉行不？？谢了，，如果把逗号去 用ing修饰就是伴随状语的用法意思是不去掉是插入语了？？这可以用的 但用同位于从句常见是啊
