牛津英语5A英语语法(二)名词复数的规则变化
情况 | 构成方法 | 读音 | 例词 |
一般情况 | 加s | 清辅音后读/s/ | map-maps |
以s,sh,ch,x 等结尾 | 加es | 读/iz/ | box-boxes |
以ce,se,ze 等结尾 | 加s | 读/iz/ | license-licenses |
以辅音字母+y 结尾 | 变y 为i 再加es | 读/iz/ | baby-babies |
二.其他复数的规则变化
1) 以y结尾的专有名词或元音字母+y 结尾的名词变复数时,直接加s变复数。例如: the Henrys’ monkey---monkeys
2) 以o 结尾的名词,变复数时:
a. 加s,如: photo---photos piano---pianos
b. 加es,如:potato--potatoes tomato--tomatoes
c. 上述a和b两种方法均可,如zero---zeros / zeroes.

a. 加s,如: belief---beliefs roof---roofs

三.名词复数的不规则变化
1)child---children foot---feet tooth---teeth注意::由一个词加 man 或 woman构成的合成词,其复数形式也是 -men 和-women,如an Englishman,two Englishmen.但German不是合成词,故复数形式为Germans;Bowman是姓,其复数是the Bowmans.
2)单复同形,如deer,sheep,fish,Chinese,Japanese ,li,jin,yuan,two li,three mu,four jin等。但除人民币的元、角、分外,美元、英镑、法郎等都有复数形式。如:a dollar, two dollars; a meter, two meters。
3)集体名词,以单数形式出现,但实为复数。例如:people police cattle 等本身就是复数,不能说 a people,a police,a cattle,但可以说a person,a policeman,a head of cattle, the English,the British,the French,the Chinese,the Japanese,the Swiss 等名词,表示国民总称时,作复数用。
4) 以s结尾,仍为单数的名词,如:a. maths,politics,physics等学科名词,一般是不可数名词,为单数。b. news 为不可数名词。c. the United States,the United Nations 应视为单数。d. 以复数形式出现的书名,剧名,报纸,杂志名,也可视为单数。
5) 表示由两部分构成的东西,如:glasses trousers,clothes等,若表达具体数目,要借助数量词 pair;suit; a pair of glasses; two pairs of trousers等。
6) 另外还有一些名词,其复数形式有时可表示特别意思,如:goods货物,waters水域,fishes(各种)鱼.
四.不可数名词对量的表示
1)物质名词
a. 当物质名词转化为个体名词时为可数。
比较:Cake is a kind of food. 蛋糕是一种食物。 (不可数)
These cakes are sweet. 这些蛋糕很好吃。 (可数)
b. 当物质名词表示该物质的种类时,可数。例如:
This factory produces steel. (不可数)
We need various steels. (可数)
c. 当物质名词表示份数时,可数。例如:
Our country is famous for tea. 我国因茶叶而闻名。
Two teas, please. 请来两杯茶。
2) 抽象名词表示具体的事例时也可数。例如:
four freedoms 四大自由 the four modernizations四个现代化
物质名词和抽象名词可以借助单位词表一定的数量,如a glass of water 一杯水/ a piece of advice 一则建议。
