问题描述：
Tom is the first person____ arrived at school today
可以填那些关系代词啊,讲下理由,
the first person 不是应该用that
答
这是一个定语从句，先行词是the first person 。先行词是序数词或他前面有序数词修饰时，如
This trian is the last that will go to SuZhou.
What is first American film that you have seen?
所以应该用that . 这答案应该真确 。多看看语法书。
答
who
答
答案：who/that.
定语从句在此修饰前面的名词person,由于先行词是人,所以关系代词用who或者that,关系代词在定语从句中充当句子的主语.
