請詳細解釋who, whom 既分別和應用~ thanks

例子：Tom loves Mary.（湯愛上瑪莉）

- Who 用來代表誰人的主詞（subject）：
例子：Who loves Mary?（誰愛上瑪莉?)

- Whom 用來代表誰人的受詞（subject）：
例子：Whom does Tom love? (誰被湯愛上?)

打錯了，受詞應該係object不是subject

其實who同whom都係relative clause中代表人既，分別就係who係主動，whom係被動
我舉兩個例子
The lady won the lottery. She lives next door.
咁這句就係用who，係個婦人羸左獎券，無提起其他人
The lady who lives next door won the lottery
第２句
The lady won the lottery. I met her last Sunday.
這句入而，因為個婦中係被你遇到，咁就係被動，就要用whom
The lady whom I met last Sunday won the lottery.


當你要講到有第２個人出視，而你係要代替第１個既就用whom,其實而家既人分唔到who同whom,就全部用哂who。我再舉多兩個例子：
The young couple come from Shanghai. Ada took them to Ocean Park last Sunday.
這句就要用whom去代替The young couple,千祈唔好搞錯這句既主角係Ada
The young couple whom Ada took them to Ocean Park last Sunday come from Shanghai.
第２個例子:
The young couple come from Shanghai.They went to Ocean Park last Sunday.
這句好明顯只有一個主角The young couple,冇其他人，咁就直接用who
The young couple who went to Ocean Park last Sunday come from Shanghai

who....係解誰(用作疑問代名詞)，通常都係喺句子嘅開頭！

例﹕Who is calling??

whom...同樣解誰(用作疑問代名詞)，但係多數出現喺句子嘅中段或結尾！

pron.(who的受格,用在正式的講話及書面語中)

例﹕Calling from whom??

希望幫到你！

who 　係　誰
whom　係　被誰

ex.
Who:
Who is mary.

Whom
She was hurted by someone whom she is not familiar with.
