she often help the students ______ she thinks are not good at English

问题描述:

she often help the students ______ she thinks are not good at English
应该用when,为什么,做什么成分的?

我认为应该使用“who” 做定语从句,修饰students可是答案用WHEN。我还觉得用WHOM呢。。因为他不少主语啊答案也可能错这里须有主语的网上所有神马提问这个问题的,其回答老师都是WHEN,就是i不说为什么,所以答案一定是WHEN那不好意思,我帮不了你!我还是相信你~
