小学英语语法
一、名词
名词是表示人或事物名称的词。它既可以表示具体的东西,也可以是表示抽象的东西。
(一)、可数名词和不可数名词
所表示的人或事物是可以按个数计算的,这类名词叫可数名词。可数名词如果名词所表示的事物是不能按个数来计算的,这类名词就叫不可数名词。
1、可数名词与不定冠词a(an)连用有数数形式,。以元音开头的单词用an 表示一个如an arm,以辅音开头的单词
用a表示一个如:a triangle
2、不可数名词不能与a(an)连用,没有复数形式如meat, rice, water, milk,不能说 a milk,但是可以与some 连用
如some milk,some water
3、名词复数规则
