Often their impact on students stays all through their lives
impact 是动词还是名词?为啥stay还要加s啊?
Often their impact on students stays all through their lives
那么on是什么词性呢?为啥跟在impact后面呢?

impact是名词,影响的意思.这句话的主干是影响持续.impact是主语,stay是谓语,因为impact是不可数名词,谓语动词当然要用单数,所以要加第三人称单数的S.
这里的on是跟后面的students联系在一起的.是个介词.指对于学生.
整句话的意思是:通常来说,他们对于学生的影响会在学生们的生命中持续很长时间.
