Pronouns（代詞）?are words we use in the place of a full noun.

We have both?subject?and?object?pronouns:
人稱代詞在句中可以用作主語(yǔ)（用主格）和賓語(yǔ)（用賓格）。

We use he/him to refer to men, and she/her to refer to women. When we are not sure if we are talking about a man or a woman we use they/them.
當(dāng)提到男的時(shí)，我們用he和him；提到女的時(shí)用she和her。當(dāng)我們不確定討論的是男還是女時(shí)，我們用they和them。

例句：

This is Jack. He’s my brother. I don’t think you have met him.

This is Angela. She’s my sister. Have you met her before?

Talk to a friend. Ask them to help you.

You could go to a doctor. They might help you.

Subject pronouns

We use subject pronouns as subject of the verb:
人稱代詞主格作動(dòng)詞的主語(yǔ)。

例句：

I like your dress.

You are late.

He is my friend

It is raining

She is on holiday

We live in England.

They come from London.

Remember: English clauses always have a subject:
謹(jǐn)記：英語(yǔ)句子都是有主語(yǔ)的。

His father has just retired. Was a teacher. > He was a teacher.

I’m waiting for my wife. Is late. > She is late.

If there is no other subject we use it or there. We call this a dummy subject.
如果沒(méi)有其他主語(yǔ)，我們用it或there代替。稱之為“形式主語(yǔ)”。

Object pronouns

We use object pronouns：

??as the object of the verb:

人稱代詞賓格做動(dòng)詞的賓語(yǔ)。

Can you help me please?

I can see you.

She doesn’t like him.

I?saw her in town today.

We saw them in town yesterday, but they didn’t see us.

? after prepositions:
人稱代詞賓格在介詞之后。

She is waiting for me.

I’ll get it for you.

Give it to him.

Why are you looking at her?

Don’t take it from us.

I’ll speak to them.?
