一个11岁的男孩用英语说后为什么year不加s?

Question

如题所述

Answer 1

短语an eleven-year-old boy 是数名结构，用来作定语，要求eleven，year，old后都不能加s并且要用连字符连接。加s只能在old后加——eleven-year-olds,就变成数名结构是名次的性质，意为“十一岁的孩子们”望采纳！

Answer 2

a 11-year-old boy 中11-year-old用连字符连接，year应当用原形，不加s，
相当于形容词，作定语修饰名词。

Answer 3

a 11-year-old boy不加s 11-year-old整体作为形容词
the boy is 11 years old要加s的追问
