可数名词的单数如何才能变为复数呢?
可数名词单数变复数规则变化
类别 规则 示例

以s、x、ch、sh结尾 词尾加-es glass→ glasses box→ boxes
watch→ watches brush→ brushes
以f或fe结尾 变f 或fe为v,再加-es shelf→ shelves knife→ knives
直接加-s roof→ roofs 屋顶
以辅音字母加y结尾 变y为i,再加-es country→ countries baby→ babies

hero → heroes 英雄
potato→potatoes tomato→ tomatoes
表示无生命的词尾加-s photo→ photos piano → pianos
radio→ radios 收音机
zoo→ zoos 动物园
可数名词单数变复数的不规则变化
规则 示例

deer→ deer 鹿
sheep→ sheep 绵羊
改变单数名词中的元音字母 foot→ feet 脚
tooth→ teeth 牙齿

可数名词的用法:
冠词 可用不定冠词a/an修饰。例如:

修饰词 可用some/any、many修饰或“数词+(量词)+of”结构来修饰。如:
three apples 三个苹果 three boxes of apples 三箱苹果
主谓一致 如果是单数名词作主语,则谓语动词用单数,如果是复数名词作主语,谓语动词用复数。例如:
The student is/comes from America. 这个学生来自美国。
These students are/come from America.这些学生来自美国。
提问数量 用“How many+可数名词复数.”。例如:
—How many bananas are there 有多少香蕉?
