代词及It用法

代词及It用法

代词是代替名词的词，英语中代词有人称代词、物主代词、反身代词、相互代词、指示代词、不定代词、疑问代词、连接代词和关系代词等九种。

一、人称代词：

(一)概述

表示“我(们)”、“你(们)”、“他/她/它(们)”等的词叫人称代词，它有人称、数和格的变化，其形式列

(二)人称代词的句法功能：

人称代词在句中的功能是通过“格”表现出来的，不同的格表明人称代词在句中有不同的句法功能。如：

1、主格形式作主语和表语。

He was late yesterday.昨天他迟到了。

They went to the cinema together.他们一起去看电影去了。

She and I are very good friends.我和她是很要好的朋友。

---Is that Mr. Smith? 是史密斯先生吗？ ---Yes, this is he.(电话用语) 是的。

It might have been she.那或许是她。

【注】①在非正式英语，尤其是口语中，人称代词作be的表语时，通常可用其宾格形式代替主格。如：---Who is it? 谁呀？ ---It’s me.是我。

②to be + 人称代词作主语的补足语时，人称代词用主格，作宾语的补足语时用宾格。如：

I was thought to be she.人们认为我是她。= They thought me to be her.

2、宾格形式作宾语(动词的宾语或介词的宾语)。

I bought a present for them. = I bought them a present.我给他们买了件礼物。

Mind you, this is just you and me.听着，这事只能你知我知，绝不可外传。

3、在比较状语从句中，在不引起误解的前提下，有时用宾格代替主格(尤其其后有同位语“all”时)。

He is taller than I (或me).他比我高。

He is taller than us all.他比我们都高。

【注】若可能引起误解，就不能用宾格代替主格。如：

He loves you more than I.他爱你胜过我爱你。

He loves you mare than me.他爱你胜过爱我。

4、用来表示感叹时，常用宾格形式。

Dear me! 哎呀/天哪! = Goodness me!

(三)代词排列次序(1—每一人称；2—第二人称；3—第三人称)

1、单数：通常按2,3,1或是3,2,1人称排列。如：

Mary and I are classmates. You, he and I are good friends.

2、复数：通常按1,2,3人称排列。如：

We, you and they have been invited to the party.

Both we and they happened to be there.

3、第三人称男女两性并用时，男先女后。如：

He and she still don’t quite agree to this plan.

4、承认过失，表示不吉祥的事，或有不好的意思时，单数按1,3,2人称排列，复数按3,2,1的人称排列。

It was I and Tom that broke the window.

I, he and you will be punished for being late.

They, you and we should leave there at once.

(四)he和she的特殊用法：

he(他)和she(她)除了用来指代男人和女人外，还可用来指代动词或无生命的东西：he可指代雄性动物

或庞大而又威猛之物。如：

Is the kitty a he or she? 这只小猫是公的还是母的？

The cat is playing with his own tail.那只猫在玩自己的尾巴。

The moon loses her brilliance when the sun makes his appearance.

太阳升起时，月亮失去了它的光辉。

【注】人们常用she/her来指代如船只、汽车、飞机、国家、城市等无生命的东西，以表达其喜爱或亲

切之情。如：

---How’s your new car? 你的新车怎么样？

---Terrific. She’s going like a bomb.好极了，劲儿象炸弹一样足。

(五)it的用法：It主要有两种用法：作代词和引导词用。

1、作代词：

(1)、作人称代词，代替前面提到的事物或身份不明的人。在性别不详或性别无关紧要时，也可指动物或

小孩（或婴儿）。如：

---Is it a boy or a girl? 是男孩还是女孩？

【注】①it与one, that的区别：one表示同类的但不是同一个，且只能代替前面的可数名词，相当于

“a/an + 名词”；that表示同类的能够是同一个，且常接后置定语；it表示的是前面同一事物，目的是为了

避免重复，可换为“the + 名词”。如：

我是怎么理解他的呢? 嗯，事情是这样的。（it指上句中提到的某件事）

如贵方速寄样品来，我方将不胜感激。（it指if从句中提到的将来的某件事）
