求助：请分析：what is it that makes her different from the other students?

是什么使她不同于其他的学生
that 引导的定语从句

简单明了主干就是
what is it ? 没了就这么简单,翻译为究竟是什么?
that makes her different from the other students是定语从句限定前面的it

究竟是什么使她变得与其他学生不一样

疑问句，对主语提问，主语从句
that指代被提问的主语，something makes her different form the other students对something提问，如果不用从句，就是what makes her.....
