He is the only one of the students that have been there.

题目

He is the only one of the students that have been there.
首先,引导词填that,但是我在搜索的过程中看到填who也对,为什么?
还有,为什么用的是have而不是has?
帮忙解答一下啊,明天月考啦

答案

应该是 has
当one of + 复数名词 被 the only 修饰时,先行词为 one ,此时that （指人,用who也对）代 one 所以接单数谓语 has
意为：他是那些学生中唯一的一个去过那里的人
如果没有the only,先行词就是 students
He is one of the students that have(复数） been there.
他是那些去过那儿的学生之一.
