初一到初三的英语语法知识点有哪些？

参考如下：

一、名词的可数与不可数

可数名词指表示的人或事物可以用数来计量，它有单数与复数两种形式。不可数名词指所表示的事物不能用数来计量。物质名词与抽象名词一般无法用数目，来统计，都成为不可数名词。

不可数名词前一般不能用冠词a、an来表示数量，没有复数形式。要表示“一个……”这一概念，就须加a piece of这一类短语。要注意许多名词在汉语里看来是可数名词，在英语里却不可数。如：chalk，paper，bread，rice，grass，news等。

二、名词复数的规则变化

A.一般情况下加-s。

B.以s, x, ch, sh, 结尾的加-es

C.以辅音字母加y结尾的改y为i再加-es

D.以f，fe结尾的，去掉f或fe，变成v再加-es
