二 词性讲解

(一)名词

1可数名词[Countable nouns]:本身可以用来计数的,表示具体概念的名词

可数名词单数:表示 “一个”的概念,单数名词前使用不定冠词a或an

 

可数名词复数:表示“两个或多个”的概念,属于复数

可数名词复数变化规律:
(1)一般直接在名词后加s,
eg: a biscuit  three biscuits
a watermelon  three watermelons.
(2)以字母-s,-x,-sh,-ch结尾单词后加es
eg: dish-dishes, bus-buses, fox-foxes, fish-fishes.
(3)特殊的几个以o结尾词加es,
骑着水牛(buffaloes)的黑人(negroes)英雄们(heroes)爱吃西红柿(tomatoes)和马铃薯(potatoes)
其余以o结尾词加s eg: photo- photos  piano-pianos  video - videos
(4)辅音字母+y结尾的,改y--ies eg: city-cities butterfly-butterflies
元音字母+y结尾的,词尾加-s  eg: key-keys  soy - soys
(5)以-f或-fe结尾的,少数直接加s,大部分改-f/-fe为-v再加es
eg: leaf-leaves  life-lives  wife-wives
(6)复合词:改中心词为复数 eg: girl student-girl students
三个特例(改复数)
man teacher- men teachers
woman nurse- women nurses

tips: 可数名词单数,谓语动词一般用单数;可数名词复数,谓语动词一般用复数。
