代词是代替名词及取名字词用途的短语或句子的词。代词一直是高考考试英语的重点。今天，我们为同学们带来了相当丰富的与英语代词有关的语法，一块儿看看吧！
代词依据其意思和使用方法可分为人称代词、物主代词、反身代词、指示代词、相互代词、疑问代词、连接代词、关系代词、不定代词九类。
人称代词的使用方法
1) 概念：人称代词是用来指代人、动物或事物的代词。它需要在人称、数（单数、复数）与性（阴性、阳性、中性）三方面与被指代的名词一致。
如：I am a student. Tom is a boy, and he is a student.
Mary is very pretty, and she likes singing.
The boys are students, and they are in the room.
The doy is small. It is Tom's.
2)人称代词的句法功能
A) 人称代词有主格和宾语之分：主格用作主语，宾格用作宾语。
B) 人称代词的主格形式在在句中作主语和表语。
如: I like music. She is a teacher.
She and I are good friends.
Neither she nor I am student.
——I saw the boys this morning.
——Are you sure it was they?
C) 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.
I haven't seen them recently.
I bought a book for them.
=I bought them a book.
☆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，用主格和宾格均可以。
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.
c. 单独用的人称代词一般用宾格，即便它充当的是主语也是这样。如：
“I like English.” “Me too=I like English too.” “我喜欢英语。”“我也喜欢。”
——Who did it?
——Them.
