1、人称代词有主格和宾语之分：主格用作主语和表语，宾格用作宾语。
如： I like music（主语）.
She is a teacher. （主语）
She and I are good friends（主语）.
Neither she nor I am student.
I saw the boys this morning.
Are you sure it was they（表语）？
2、人称代词的宾格在句子作动词的宾语，或者介词的宾语。
如：I saw him at the party（动词see的宾语）。
I haven't seen them recently. （动词see的宾语）
I bought a book for them.（作介词for的宾语）
=I bought them a book.（作介词buy的间接宾语）
注意：
a.在口语中，人称代词的主格形式作表语时，常常可以用宾格替换。
如：It can't be he/him.
Is this Mr. Green?
Yes, this is he/him.
b. 在口语中，当人称代词用于than, as 之后或用于强调句中被强调时，用主格（较正式）和宾格（较口语化）均可以。
如：He sings better than I/me. 他比我唱得好。
You know more than she/her.
She is as tall as me （me=I am）。
c. 单独使用的人称代词通常用宾格，即使它充当的是主语也是如此。如：
"I like English." "Me too=I like English too." "我喜欢英语。""我也喜欢。"
Who did it?
Them.（=They did it）
