名词复数变化
规则变化
1) 一般情况加s
例如:map-maps boy-boys girl-girls pen-pens bag-bags car-cars
(清辅音后读/s/,浊辅音和元音后读/z/,/s/、/z/、/dʒ/等音后发/iz/) 2) 以s, sh, ch, x结尾加es,读/iz/。
例如:bus-buses watch-watches box-boxes brush-brushes 3) 以辅音字母+y结尾,变y为i再加es,读/iz/。 例如:baby---babies city-cities country-countries
4) 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,读/z/ monkey---monkeys holiday---holidays Mary---Marys(专有名词) 5)以辅音字母+o结尾的,加es,读/iz/。
例如:potato- potatoes tomato-tomatoes hero-heroes Negro-Negroes 7) 有些以辅音+o结尾的名词,直接加s,读/z/.
例如:piano-pianos photo-photos alto-altos soprano-sopranos quarto-quartos(四开本)
8)有些以f或fe结尾的,把f或fe变ve加s,例如:leaf-leaves shelf-shelves
不规则变化
1) child---children foot---feet tooth---teeth mouse---mice man---men woman---women
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. 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。
The United Nations was organized in 1945. 联合国是1945年组建起来的。 d. 以复数形式出现的书名,剧名,报纸,杂志名,也可视为单数。例如: \"The Arabian Nights\" is a very interesting story-book. 《一千零一夜》是一本非常有趣的故事书。
5) 表示由两部分构成的东西,如:glasses (眼镜) trousers, clothes等,若表达具体数目,要借助数量词 pair(对,双); suit(套); 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。
7) 有些表示生物的名词,其复数形式与单数相同。如:fish-fish, sheep-sheep, deer-deer。这类名词还有aircraft, means等
不可数名词
1) 物质名词
2) a. 当物质名词转化为个体名词时为可数。
3) 比较:Cake is a kind of food. 蛋糕是一种食物。 (不可数) 4) These cakes are sweet. 这些蛋糕很好吃。 (可数) 5) b. 当物质名词表示该物质的种类时,可数。例如: 6) This factory produces steel. (不可数) 7) We need various steels. (可数)
8) c. 当物质名词表示份数时,可数。例如:
9) Our country is famous for tea. 我国因茶叶而闻名。 10) Two teas, please. 请来两杯茶。
11) 2) 抽象名词表示具体的事例时也可数。例如:
12) four freedoms四大自由the four modernizations四个现代化
13) 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 a piece of advice
14) a pile of caol a flash of lightening a burst of laughter
