初一英语的知识点很细，一个单词、一个词组或许就包含着一个知识点，更何况还有那么多的句式和语法。下面小编整理了初一英语知识点，希望能对大家的初一英语学习有所帮助。
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.
