初中英语语法大全——名词

初中英语语法大全——名词 一、名词概述 1.名词的定义 名词是表示人、事物、地点、现象及其他抽象概念等名称的词。英语中的名词有可数名词和不可数名词之分;有其所有格形式;在句子中通常做主语、宾语、宾语补足语、表语、定语等。 2.名词的分类 名词分为专有名词和普通名词两类。普通名词又分为个体名词、集体名词、物质名词和抽象名词。个体名词与集体名词多数是可数名词,而物质名词与抽象名词多数是不可数名词。

二、名词的数 名词按照其可数性可以分为可数名词和不可数名词。可数名词是指可以直接计算数目的名词。个体名词和集体名词多数是可数名词;不可数名词是指无法直接用数目计算的词。物质名词和抽象名词多数是不可数名词。 1.可数名词的数 在英语中,可以直接用数字进行计算的名词是可数名词,不能直接用数字进行计算的名词是不可数名词。通常个体名词和集体名词可以用数目来计算,视为可数名词;物质名词和抽象名词往往指泛指的物质或者抽象的概念,不能用具体的数字来表示,视为不可数名词。专有名词往往只指一个人或物,因此没有必要再用具体的数字来修饰,一般也视为不可数名词。

eg: I was having dinner at a restaurant. eg: The two children are playing table tennis in the school. eg: Mr.Black gave us some advice on how to learn English well. eg: Paris is the capital of France. ①规则复数变化形式 可数名词在表示两个或两个以上的概念时需要用复数形式。可数名词单数形式变成复数形式的一般规则如下表:
