代詞是代替名詞及起名詞作用的短語或句子的詞。代詞一直是高考英語的重點(diǎn)。今天，小編為同學(xué)們帶來了相當(dāng)豐富的與英語代詞相關(guān)的語法，一起來看看吧！

?

代詞根據(jù)其意思和用法可分為人稱代詞、物主代詞、反身代詞、指示代詞、相互代詞、疑問代詞、連接代詞、關(guān)系代詞、不定代詞九類。

人稱代詞的用法

1) 定義：人稱代詞是用來指代人、動(dòng)物或事物的代詞。它必須在人稱(第一人稱、第二人稱、及第三人稱)、數(shù)（單數(shù)、復(fù)數(shù)）以及性（陰性、陽性、中性）三方面與被指代的名詞一致。

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)人稱代詞的句法功能

A) 人稱代詞有主格和賓語之分：主格用作主語，賓格用作賓語。

B) 人稱代詞的主格形式在在句中作主語和表語。

如: I like music(主語). ??????????She is a teacher.(主語)

She and I are good friends(主語).

Neither she nor I am student.

——I saw the boys this morning.

——Are you sure it was they(表語)?

C) 人稱代詞的賓格在句子作動(dòng)詞的賓語，或者介詞的賓語。

如：I saw him at the party(賓語).

I haven't seen them recently.(賓語)

I bought a book for them.(作介詞賓語)

=I bought them a book.(間接賓語)

☆注意：

a.在口語中，人稱代詞的主格形式作表語時(shí)，常?？梢杂觅e格替換。

如：It can't be he/him.

——Is this Mr. Green?

——Yes, this is he/him.

b. 在口語中，當(dāng)人稱代詞用于than, as 之后或用于強(qiáng)調(diào)句中被強(qiáng)調(diào)時(shí)，用主格(較正式)和賓格(較口語化)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(I am).

c. 單獨(dú)使用的人稱代詞通常用賓格，即使它充當(dāng)?shù)氖侵髡Z也是如此。如：

“I like English.” “Me too=I like English too.” “我喜歡英語。”“我也喜歡?！?/p>

——Who did it?

——Them.(=They did it)
