someone后面接定语从句用who还是that

someone后面接定语从句用who，具体内容如下。

关系从句的句法功能主要是充当定语。在英语中，关系从句通常位于它所修饰的词（组）之后。被关系从句修饰的词（组）叫做先行词（英语：antecedent），引导关系从句的词称为关系词，关系词指代先行词并在关系从句中充当一定的成分。例如：

This is the book which interests me.（“which interests me”是关系从句，修饰先行词“book”，而关系词“which”指代先行词“book”并在关系子句中充当主语。这句话可以拆分为两个句子来理解：“This is the book.”和“The book interests me.”）

后面用that，例如：

1、I just need to tell someone that I love them.我得去告诉别人我爱他们。

2、I think there's someone that wants to see you.我想你会非常想见某人

3、I don't think I could fall for someone that quickly.我想我不会那么快就喜欢上一个人。

someone是后面引导的从句先行词不一定只用that，也可用who。

定语从句的先行词为指人的all， one，ones，someone，anyone，everyone，no one等代词时，引导词只能用who。

One who doesn’t work hard will never get happiness.

不努力工作的人，永远得不到幸福。

Do you know anyone who can mend locks?

你认识会修锁的人吗

但是如果定语从句缺主语 that就不能用了 因为that不充当成分 只能用who。

there is someone who loves you.

有爱你的人。

there is something that you dont know.

有你不知道的事情。
