英语语法里面，感觉最难，最复杂的就是从句了。我们在使用从句的时候，经常能看见Who,偶尔能看见Whom，Whose。那它们到底有什么区别呢！一起来看看吧

1.I met a man who knows you.

我遇到了一个男人，这个男人认识你

2.I met man whose sister knows you.

我遇到了一个男人，这个男人的妹妹认识你

所以Whose表示‘谁的’意思哦

Note:

We use whose mostly for people:

大部分时候 我们用whose来形容人

举个栗子，先看看Whom怎么用：

Example: The woman whom I wanted to see was away on holiday.

拆出这个从句就是 I wanted to see whom，这里的Whom在这里是宾语，指The woman.

而Who与Whom的区别是：

WHO 可以做主语,又可以做宾语

Whom只能做宾语

所以：

I wanted to see whom，做宾语的时候Whom Who可以互相替换，变成I wanted to see who

但：你没有听过Whom are you吧，因为这是错的。Whom不能做主语哦~

结论：Whom is possible instead of who when it is the object of the verb in the relative clause

当Whom指代宾语的时候，Who可以替代Whom

反过来，Whom 不可以替代Who（当Who 是主语的时候），你没有听过Whom are you吧，因为这是错的。

所以一般用Who就足够了，至于Whom,加分项

BTW:

You can also use whom with a preposition

你也可以用whom加一个介词

Example:The woman with whom he fell in love left him a few weeks

拆成两个句子:

He fell in love with the woman.The woman left him a few weeks.

But we do not often use whom. In spoken English we usually prefer who or that,or nothing

在口语里面，我们不经常使用whom，我们会用who/that。有时候也会直接省略who/that。

例如：

1. The man I saw went away. (The man后面已省略who/that)

2.The man who/that I saw went away. (用who/that)
