初中英语代词知识点：人称代词句法作用

A)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)?

B) 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 havent 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 cant 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)
