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

1.一般情况下,直接加-s,如:book-books, bag-bags, cat-cats, bed-beds

2.以s. x. sh. ch结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches

3.以“辅音字母y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries
