一、名词:名词是所有事物的名称,包括人、物及抽象概念。名词分为普通名词和专有名词两大类。名词在句子中作主语,宾语或表语等。
1.普通名词 普通名词是某类人、事件、物体和抽象概念的名称。根据所指代物体的特征,普通名词又可分为以下四类:
A.个体名词: 表示人或物体中可以数清的单个体。如:student(学生)、pen(钢笔)、bird(鸟)等。
B.集体名词: (即集合名词)表示由个体组成的集合体。如:people(人民)、police(警察)、family(家庭)等
C.物质名词: 表示构成物体物质的不可数名词,或表示无法分为个体的物质的名词。如:water(水)、air(空气)、wood(木头)等。
D.抽象名词 : 表示动作、状态、品质、情感等非具体化的抽象概念。如:work(工作)、peace(和平)、love(爱)等。
2. 专有名词 : 专有名词是某些人、事物、机构、组织等特有的名称。主要包括:人名、地名、国名、党派名称等。如:Churchill(丘吉尔)、Tokyo(东京)、China(中国)等。
二、可数名词和不可数名词。
1) 可数名词: 一般来说个体名词和集体名词可以用数目来计算,称为可数名词。可数名词有单数和复数两种形式。
例如: a book, two books, a student, three students, a family, many families。
名词单数变复数变化如下:
1.词尾直接加 S 如:cat--cats bag--bags day--days
2.以 S, SH, CH, X 结尾的词加 ES 如:class--classes match--matches box----- boxes dish ---- dishes
3.以辅音加 Y 结尾的词变 Y 为 I, 加 ES. 元音加 Y 结尾的词直接加 S,
如: party----parties city----cities story----stories
boy---- toys monkey----- monkeys key---- keys 等.
4.以 F 或 FE 结尾的词, 变 F 或 FE 为 V, 加 ES,
如: wife ---- wives half---- halves 注意特殊情况直接加“S”,要逐个记 chiefs,handkerchiefs, roofs.
5.以辅音加 O 结尾的词常加 ES, 如: tomatoes, potatoes, heroes. 元音加 O 结尾直接加 S. 如:radios, zoos, pianos.特殊情况: photos
6.名词单数变复数特殊变化也要逐个记得如: man-men, woman-women, tooth---teeth, goose---geese, foot---feet, child--children, mouse-mice
2) 不可数名词
不可数名词不能用数字计算包括物质名词( air, water等)及抽象名词(advice, hate)等。所以它通常只有单数形式。如:English, air, water, cotton, work...
不可数名词表示数量时,可以用量词来表达(量词有复数形式)其结构是数词+量词+OF+名词。如:a bottle of water,two cups of tea,three pieces of paper
注意事项:
1.不可数名词没有复数变化,不能用A,AN,但可用THE,或不用冠词,如:bread is the usual breakfast.
2.虽然不可数名词没有复数变化,但量词超过一时要加复数。
如:three cups of coffee, five bottles of water
3.有量词修饰时注意名词是否可数,不可数时用单数,可数时用复数,如:ten bags of rice---- ten baskets of eggs
