什么是单数和复数名词？
单数名词指的是一个人、地点、事物或想法。复数名词则指的是多于一个人、地点、事物或想法。
构成
大多数复数名词通过在单数名词后加 '-s' 构成。例如：
单数名词 | 复数名词 |
|---|---|
cat (猫) | cats (很多猫) |
boy (男孩) | boys (很多男孩) |
cup (杯子) | cups (很多杯子) |
pencil (铅笔) | pencils (很多铅笔) |
desk (桌子) | desks (很多桌子) |
apple (苹果) | apples (很多苹果) |
拼写
如果单数名词以 s, x, z, ch 或 sh 结尾，复数形式通过加 '-es' 构成。
单数名词 | 复数名词 |
|---|---|
church (教堂) | churches (很多教堂) |
boss (老板) | bosses (很多老板) |
dish (盘子) | dishes (很多盘子) |
box (盒子) | boxes (很多盒子) |
quiz (小测验) | quizzes (很多小测验) |
如果单数名词以辅音加 '-y' 结尾，复数形式通过将 '-y' 替换为 '-ies' 构成。例如：
单数名词 | 复数名词 |
|---|---|
city (城市) | cities (很多城市) |
baby (婴儿) | babies (很多婴儿) |
不规则名词
一些名词有不规则的复数形式。例如：
单数名词 | 复数名词 |
|---|---|
man (男人) | men (很多男人) |
woman (女人) | women (很多女人) |
child (孩子) | children (很多孩子) |
tooth (牙齿) | teeth (很多牙齿) |
foot (脚) | feet (很多脚) |
fish (鱼) | fish (很多条鱼) |
sheep (羊) | sheep (很多只羊) |
动词一致
当名词作为主语时，单数名词应与单数动词搭配，复数名词应与复数动词搭配。请注意以下例子：
Your eyes are blue.
你的眼睛是蓝色的。
A glass is on the table.
