英语中宾语从句的 whichwherethatwhom who 怎么区分

我可以详细回答下whom 与 who
1. whom 与 who 都是 代词
2. 都可以作为疑问代词和关系代词
3. who 必须用作一个 动词的主语whom必须用作动词的宾语（这个请看例句）
例句之前以下是我学习 Sentence Structure(句子结构) 的笔记 对who/whom的定义:
How to using the pronouns who and whom? Remember!Who is in the subjective case and must be used as the subject of a verb.Whom is in the objective case and must be used as the direct object of a verb or as the object of a preposition.
TIP!Find the verb and ask,“who or what is the subject of the Verb?”
技巧!先找到动词,然后问谁或什么是这个动词的主语?
以上定义
who/whom 作为 疑问代词的例句
(Who,Whom) did you invite to the party?咱寻找一下 这句动词是"invite", 然后主语是you有了主语you 及物动词invite 就需要宾whom, 所以这句应该是 whom did you invite to the party?
(Who,Whom) is your favorite athlete?首先先找动词 is 然后找主语 这你就可以看到主语其实是咱正询问的... 所以. 句子就是 who is your favorite athlete?
以下是作为 疑问代词的例句
She is the one (who,whom) hates me.她就是那个#恨我#的人who
She is the one (who,whom) I love.她就是那个#我爱#的人whom
