答：當定語從句所修飾的先行詞是指人的名詞或代詞時，我們一般都可以用關係代詞who/ that來引導定語從句。who/ that可以用作主語或者賓語（注：口語中作賓語時常用who, 但是在正式語體中作賓語的多用whom). 下面主要是列舉who/ that用作主語，引導定語從句的例項：

He who/ that has never been to the Great Wall isn"t a true man. John is the very man that is right for the job. The man who/ that is speaking to our teacher is a famous scientist. Is this professor the one who/ that often helps you with your maths? The nurse who/that looks after my baby is my younger aunt. Is this the boy who/that plays soccerball best in your class? He is not the man that/who he used to be. She is the only person who/ that serves as our guide. The lady that/ who helped you just now is a friend of mine. I was the only person in my office who/that was invited to the party.
