中考真题学英语丨three-year-old为什么不能加s?(文末附练习题)

湖南郴州中考真题：

-Look at the girl in a square! 

-Oh, I'm surprised that a _______ girl can dance so well 

A.three-years-old

B.three-year-old

C.three years old

重点来了：

✅ three-year-old 是复合形容词，作为定语修饰后面的名词。

中间有连字符 -，名词 year 必须用单数 year，比如：

athree-year-oldboy.一个三岁的男孩。

✅ three years old  短语作表语，放 be 动词后，后面不加名词，
