一、可数名词在它之前可以加上冠词a/an (以元音字母a,e,i,o,u开头的字母前冠词用an)。
而不可数名词前面是不可以直接加冠词的。
可数名词复数变化规律如下:a. 一般情况下,直接力卩-s,女口:book-books, bag-bags, cat-cats, bed-beds ;读音:清辅音后读[s],浊辅音和元音后读[z]。

二.不可数名词:
⒈不可数名词概念:不可以数的名词叫做不可数名词。
包括物质名词(表示无法分为个体的物质)和抽象名词(表示抽象概念的词)。
⒉不可数名词特点:
⑴不可数名词没有复数形式,也不能与a, an及数词连用,常作单数看待。
例:water There’s some water in the bottle.
food My favourite food is noodles.
⑵不可数名词如表数量,常和a bottle of, a glass of等名词词组连用。
如表示复数,只把量词改为复数。
例:a bottle of pop一瓶汽水, two glasses of orange juice 两杯桔子汁,
three cups of tea 三杯茶,a piece of paper一张纸
⑶有些物质名词有时可数,有时不可数,要根据上下文决定,其意义也有所不同。
A glass is made of glass.玻璃杯是玻璃制成的。
(玻璃杯可数,玻璃不可数。
)
I bought a melon yesterday. I want to eat some melon.
特殊名词的讲解:
⑴people 作“人们,人民”解时,只有复数形式,谓语动词作复数。
作“民族”解时,单复数不同,复数要在词尾加s。
There are five people in my family. 我家有五口人。
There are fifty-six peoples in our country.我们国家有56个民族。
⑵clothes,pyjamas等属于无单数形式的复数名词,谓语作复数。
例:My favourite clothes are pants. These pyjamas are too small.
⑶pants , shoes , glasses ,shorts,scissors等名词,由两部分构成,常以复数形式出现,谓语动词要用复数。
要表示单数常用a pair of表示,此时如作主语,谓语要作单数看待。
例:Your pants are blue. This pair of pants is mine.
⑷集体名词看作整体时,谓语用单数; 指成员时,谓语用复数。
His family is a large family. His family like animals.
指整体指成员
⑸有的名词单复数意思不同:
例:hair 和fruit 通常作单数,表示总体。
My hair is black. 我的头发是黑色的。
I like fruit .It’s good for you.我喜欢水果,水果对你的身体有好处。
但如果表示若干根头发或各种水果,则需用复数形式.
Danny has three hairs.丹尼有三根头发。
She likes pears, peaches and other fruits. 他喜欢梨,桃和其它水果。
