who 同 whom 的分別 ......

who 同 whom 的分別 ......
在講代名詞who, whom兩字分別之前，先要說：
whom 字古舊，已不常見於日常對話和較 informal 的文體，所以寫作時不必勉強用它（但 for whom，with whom，all of whom 等關係子句句式則作別論）。例子:
1. By whom it was founded?
2. For whom did respondent vote in presidential election?
3. He wants to marry a girl with whom he had a relationship.



who 和 whom 的分別，跟 he 和 him 的分別沒有兩樣。也就是說：
who 和 he 都是作subject時用；whom 和 him 都是作 object 時用。
舉個最簡單的例子。
I love him.
我們用 him，是因為「他」是句子中的 object(受詞)；
相反，如果「他」是句中 subject(主詞)，則要用 he：例子
He loves me. 疑問代名詞who, whom疑問代名詞問句的形成，是將疑問代名詞取代肯定句的主詞或受詞，主詞補語。以形成疑問句。所以疑問代名詞的問句句型可以分為疑問詞當主詞、受詞或名詞補語這三種。」 肯定句Yes/ No問句疑問代名詞Information 問句 主詞He is your brother.Is he your brother?who代替heWho is your brother?主詞補語He is Ken.Is he Ken?Who
代替KenWho is he?受詞You like Ken.Do you like Ken?who（whom）
代替KenWho do you like?= Whom do you like?

1. who is SUBJECT
e.g.: Who is your best friend?

e.g.: Who met you yesterday?
May met me yesterday. [May is the subject]

2. whom is OBJECT
e.g.: Whom do you play with everyday?

e.g.: You sat by whom all night?
I sat by my daddy all night. [Daddy is the object]
e.g.: Clarie saw whom yesterday?

3. Always use whom after PREPOSITION
(e.g. to,with,on,by,in,near,etc.)
e.g.: With whom did you see Janice?
I saw Janice with Kiki. [Kiki is the object]
e.g.: This is the lady whom I made the promise to.
I made the promise to this lady. [This lady is the object]
e.g.: With whom did you go to the cinema?
I went to the cinema with my mum. [Mum is the object]

subject: who do sth/actions
e.g.: She did her homework yesterday.
object: who is related to the actions
e.g.: She did the homework with her sister yesterday.

p.s. words in blue colour are verb/action :D
