who在定语从句中作主语，正确吗？

Question

如题所述

Answer 1

回答如下：
本句完全正确。关系代词who指代先行词one (指人)，who在定语从句中作主语。
先行词被only修饰时，如果先行词指人，则可以用关系代词who / whom / that; 若先行词指物，则不能用关系代词which, 要用that。例如：
He is the only person that / who has won the prize.
You are the only man that / who / whom I want to see.
This is the only car that I bought.
She is the only one (指人)that / who knows French.
