Unit 3 The Earth Grammar名词的数
1.关于可数名词。
可数名词有单数和复数两种形式。指一个人或一件事物时，用单数形式指两个或多个人或事物时用复数形式。名词由单数形式变成复数形式的规则如下:
可数名词复数形式的构成：
规则变化：
__________________________ 如：cap— cake—
_____________________________如：glass— watch—
_____________________________如：shelf— knife—
______________________________如：story— baby—
_________________________如：potato— hero—
②不规则变化：
改变元音字母，发音也随之变化：
man(人；男人)— woman(女人)—
postman(邮递员)— fireman(消防员)—
foot(脚)— tooth(牙齿)—t
goose(鹅)—
a man teacher(一名男老师)— a woman nurse(一名女护士)—
b. 单复数同形的词：
a sheep(一只羊) — a fish（一条鱼）— a deer（一头鹿）—
c. 通常以复数形式出现的名词：
scissors(剪刀) — trousers(裤子) — clothes(衣服) —
glasses(眼镜) — shorts(短裤) —
d. 表示“某国人”的单复数：
单数和复数相同， 如：a Japanese— a Chinese—
变man为men, 如：an Englishman— a Frenchwoman—
词尾加-s, 如：a German— an American—
【总结】中日不变，英法变，其他“s”加后面 e.
其他形式：a child—two children an ox—three oxen(三头牛) a mouse—four mice（四只老鼠）
不可数名词的数:
不可数名词通常只有单数形式，前面无需加不定冠词a/an。
如：water, milk, oil, soil, ink, bread, juice等。
但如果需要表示具体的数量时，要使用以下短语：
a glass of juice a piece of paper a slice of bread
注意：people单数形式表示复数意义，要求谓语动词用复数people的复数形式peoples通常指“多个民族”。
