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

We have both subject and object pronouns:
人称代词在句中可以用作主语（用主格）和宾语（用宾格）。

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.
当提到男的时，我们用he和him；提到女的时用she和her。当我们不确定讨论的是男还是女时，我们用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:
人称代词主格作动词的主语。

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:
谨记：英语句子都是有主语的。

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.
如果没有其他主语，我们用it或there代替。称之为“形式主语”。

Object pronouns

We use object pronouns：

• as the object of the verb:

人称代词宾格做动词的宾语。

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:
人称代词宾格在介词之后。

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.
