第一章名词

●名词的数

一、可数名词和不可数名词的区别

1.定义:

可数名词:普通名词中的个体名词和集体名词可以用数目来计算,有单复数之分

不可数名词:没有单复数之分,物质名词和抽象名词属于不可数名词

2.可数名词和不可数名词的主要区别:

1)可数名词可以被a/an修饰,且有复数形式,而不可数名词不可以被a/an修饰,且没有复数形

2)有些限定词只能修饰可数名词,某些则只能修饰不可数名词,而某些则既能修饰可数名词又能

修饰不可数名词

✓只能修饰可数名词的有:few, many= a number of, a great/good many, a great many of等

✓只能修饰不可数名词的有:much, little, a large amount of, a great deal of

✓即可修饰可数名词又可修饰不可数名词的有:some, any, plenty of, a lot of, a large quantity of

✓只能修饰可数名词单数的有:many a, more than one

3)有些不可数名词有相应的名词表其个体:

二、可数名词复数的构成规则如下:

1.大部分名词构成复数时,在词尾加s,如:

2.以因素[s] [z][ tʃ][dʒ] [ʒ] ,结尾的名词构成复数时,在词尾加- es,如,

3.以辅音字母加y结尾的名词构成复数时,直接加s,如:

City- cities, party- parties, body- bodies

4.以元音字母加y结尾的名词构成复数时,直接加s,如:

Boy- boys, play- plays, day- days, key- keys

5.以辅音字母加o结尾的名词构成复数时,通常在词尾加es,也有特殊情况,如:

1)Hero- heroes, potato- potatoes, tomato- tomatoes, negro- negroes, mango- mangoes, buffalo-

buffaloes, echo(回声)-echoes, tornado(龙卷风)- tornadoes, torpedo(鱼雷)- torpedoes, domino(多米诺

铭)-mottos, cello(大提琴)- cellos

3)一些缩写词和专有名词,在词尾加s,如:

7.一些以f, fe结尾的名词构成复数时,把f, fe变成v, 再加es,如:

Half- halves, leaf- leaves, knife- knives, thief- thieves,self-selves, life- lives, wife- wives, shelf- shelves, loaf- loaves, wolf- wolves

口诀:为了自己活命,小偷和他的妻子手里拿着刀子和一片树叶站在架子上,把狼劈成了两半

9.名词变复数不规则变化大体有以下变化

1)单复数形不同,如

Man –men, woman- women, foot- feet, tooth- teeth, mouse- mice, child- children, emphasis( 强调)- emphases

注:以man构成的合成词,是man变成men如:

Englishman- Englishmen, Frenchman- Frenchmen, dustman- dustmen

但German- Gemans, human- humans因为他们不是合成词

2)单复数词形相同,如

Deer, sheep, fish, works,(工厂) means( 方式、途径), Chinese, Japanese, Swiss, bellows( 风箱), series, crossroad, horsepower及由汉语拼音拼出的计量单位,如: yuan, li, jin,英语中原有的计量单位不在此

列,如:dollar- dollars, pound- pounds, metre-metres

除上述情况外,关于名词数的问题还应注意以下几个方面

有些名词只有复数形式,一般不直接受数词或a(an)修饰,如果要表示数量用相应的起量词作用的名词。Clothes, glasses, trousers, compasses, scissors( 剪刀)等

A pair of glasses, two suits of clothes

注意:此时谓语动词和前面的量词保持一致。如

A pair of glasses is on the table

Two pairs of glasses are on the table

3)有些名词只有复数,没有单数

Police, people, cattle

4)有些集合名词即可做单数,指整体;又可作复数,指该集体的成员,指整体时,谓语用单数;指成

员时,谓语用复数。常用的名词有:

Family, class, group, team, party, public等。

比较下列句子

The team is made up of 12 members

The team are having a bath now

My family is going to move to Paris

My family usually watch TV after supper

5)合成名词的复数形式,通常将其中所包含的中心词变为复数,如

passer-by变成passers-by, grown-up变成growns-up, father –in –law 变成fathers -in –law, boy student- boy students

6)以s 结尾的专用名词,如: the New York Times, the United Nations, the United States等,表示事物的

整体,谓语用单数,但有些表示群岛,山脉的专有名词,谓语常用复数。如:

The United States is a highly developed country

The Alps are in Europe

7)字母、数字、引语或缩略(词)语的复数形式是在其后加‘s或s,如

There are two f‘s in the word ”office”

Many VIPs are coming to our city

8)名词作定语,通常用单数形式,即使在意义上是复数的(如shoes)或总用作复数的名词(如trousers)

也是如此如:

There are twenty boy students in our class

They are his girl friends

Trouser pockets

注意:

a)当sports, customs, arms, clothes, sales 和accounts做定语时,不能变成单数修饰名词,如
