高中英语语法学习 普通名词
普通名词指一类人或事物的名称。英语中普通名词分为可数名词和不可数名词。
可数名词一般有单、复数两种形式。如a/one child,ten children。而不可数名词一般只有一种形式。如cash(现金)。不可数名词之前不可直接用泛指限定词和数词。不可数名词可与some一起用。如:some money,some water。也可与the一起用:the information(这信息)。

a. 加s,如: photo---photos piano---pianos

(二)可数名词和不可数名词
英语中的绝大多数名词既可以用作可数名词也可以用作不可数名词。
1.可数名词
可数名词一般可以分成以下二类:
第一类:如bike,desk, factory等,这类名词占可数名词的多数。以bike为例:
There are fifty bikes at this shop.这家商店有50辆自行车。
第二类:如clothes等,本身表示复数形式。以clothes为例:
She cares for nice clothes.她爱好穿着。
2.不可数名词
不可数名词的用法特征主要有以下几种:
(1)不带冠词的单数形式需用动词单数作谓语。例如:
Knowledge is power.知识就是力量。
(2)由much,little等词修饰。例如:
They have saved much money for future use.他们存了很多钱以备未来使用。
(3)与表示单位的量词如a piece of等连用。例如:
Go and fetch me a piece of chalk.给我去拿一支粉笔。
要十分注意的是:不可数名词不能与不定冠词或数词直接用在一起。如不能说a good news, an advice, a hard work等。
不可数名词可以与量词使用构成不同的词组:
如: a piec e of paper 一张纸 a drop of water 一滴水
a 1oaf of bread 一条面包 a bag of money 一袋钱
a bottle of milk 一瓶牛奶 a pair of shoes 一双鞋 高中英语语法学习 普通名词
