the problem with students in Grade 9 is that if we should keep our hobby.

问题描述:

the problem with students in Grade 9 is that if we should keep our hobby.

这句话总体上是没有语法问题的.
但应该写为The problem of sutents in Grade 9 is that whether we should keep our hoppy or not比较地道一些problem后面为什么要用of而不是with固定搭配,更加地道一些。stress for Grade 9 is so large 有问题么你是想表达什么意思?初三有很大压力
