初一英语知识点梳理

人称及人称代词的不同形式

1、三种人称:第一人称(I,we),第二人称(you,you),第三人称(he,she,it,Maria)。

2、人称代词的宾格,即人称代词位于句子宾语位置时的形态:me,us,you,you,him,her,it。

3、形容词性物主代词:my,our,your,your,his,her,its,their。

4、名词性物主代词:mine,ours,yours,yours,his,hers,its,theirs。

this,that和it用法

(1)this和that是指示代词,it是人称代词。

(2)距离说话人近的人或物用this,距离说话人远的人或物用that。如:

This is a flower. 这是一朵花。(近处)

That is a tree. 那是一棵树。(远处)

(3)放在一起的两样东西,先说this, 后说that。如:

This is a pen. That is a pencil. 这是一支钢笔。那是一支铅笔。

(4)向别人介绍某人时说This is…, 不说That is…。如:

This is Helen. Helen, this is Tom. 这是海伦。海伦,这是汤姆。

(5)This is 不能缩写, 而That is可以缩写。如:

This is a bike. That’s a car. 这是一辆自行车。那是一辆轿车。

(6)打电话时,介绍自己用this, 询问对方用that。如:

—Hello! Is that Miss Green? 喂,是格林小姐吗?

—Yes, this is. Who’s that? 是的,我是,你是谁?

注意:虽然汉语中使用“我”和“你”,但英语中打电话时绝不可以说:

I am…, Are you…?/Whoare you?

(7)在回答this或that作主语的疑问句时, 要用it代替this或that。如:

①—Is this a notebook? 这是笔记本吗?

—Yes, it is. 是的,它是。

②—What’s that? 那是什么?

—It’s a kite. 是只风筝。

句子单数变复数

(1)主格人称代词要变成相应的复数主格人称代词,即I→we,you→you,she,he,it→they。如:

She is a girl. →They are girls.

(2)am,is要变为are。如:

I’m a student. →Weare students.

(3)不定冠词a,an要去掉。如:

He is a boy. →They are boys.

(4)普通单数名词要变为复数形式。如:

It is an apple. →They are apples.

(5)指示代词this,that要变为these,those。如:

This is a box. →These are boxes.
