一道选择题
－－－children are too young to go to school
A four－year－old
B four－years－old
C four years old
D four year old
答案是A．为什么A是对的？为什么C不对？麻烦分析一下

four-year-old 和four years old都可以指“四岁”，但用法上有不同。
前者只能用在名词和人名前，作定语。后者只能用在名词、系动词之后，作表语。

A为形容词，在这里可以修饰名词
而C则作为表语
类似于face-to-face，face to face

因为four－year－old 是定语,可修饰名词
而four years old是表语,不可修饰名词

因为句中要的是一个形容词啊
