who是人称代词吗？为什么who有宾格形式whom呢？

who是人称代词吗？为什么who有宾格形式whom呢？如题

Answer 1

英语中人称代词（Personal Pronoun）意为用于指代人的词汇，属于代词范畴，就像汉语中的“你”、“我”、“他”。常用的英语人称代词有：I、you、he、she、it（主格）。
who 与whom 都可用作疑问代词,who 是主格,whom是宾格。
例如: Who saw the thief? 谁看见了那个 ?
Whom are you trying to fool? 你想愚弄谁啊?
在日常口语中,常用who 代替whom作宾语。
我们可以说Who are you trying to fool?
但是who 不能直接用在介词后面。若直接用在介词后面,就必须用whom。
例如: To whom is she writing? 她在给谁写信?
如果用who一般是在不正式的场合用.
另外to whom和把to放在后面都是可以的,比如:
Whom do you wait for?
= For whom do you wait?

Answer 2

who 不是人称代词，它兼疑问代词和关系代词两职。
在特殊疑问句中，作疑问代词；在定语从句中作关系代词；此外在名词从句中还作引导词，下面给出一些例句：
疑问句
Who asks you?
Whose house is this ?
Whom do you depend on
定语从句
This is the man who tells me the news.
Do you recognize the man whose hat is black.
The man whom you want to see is in the office.
名词从句
Please tell me who he is.
Have you determined to whom you will give this prize.
He inquires whose house this is.
可以看到 who 有主格、所有格和宾格。有些时候，宾格 whom 可以被 主格who代替。在此不作讨论。
这三种句子有时会混，要花点功夫。

Answer 3

who 可以做主语,又可以做宾语
whom 只能做宾语
例子：1,who are you?不能是whom are you?
2,This book belongs to whom/who?两者都可以
1.who指人,在从句中做主语
(1) The boys who are playing football are from Class One.
(2) Yesterday I helped an old man who lost his way.
2.whom指人,在定语从句中充当宾语,常可省略.
(1) Mr.Liu is the person (whom) you talked about on the bus.
(2) Mr.Ling is just the boy whom I want to see.
注意：关系代词whom在口语和非正式语体中常用who代替,可省略
简单点说就是：
Whom 只能出现在从句里面或是介词（如 to,from,at,of..）后面.
1． Whom 出现在从句里面时,所有用whom的地方都可以用who代替.Whom 这个词只出现在很正式的书面语.口语不用.
2． Whom 在介词（如 to,from,at,of..）后面时,不可替换.
