eight-year-old 表示8岁的。。when i eight-year-old ，这句话对么？是我8岁的时候

Question

如题所述

Answer 1

不对，eight-year-old 是形容词 只能说 when I was an eight-year-old boy.
eight years old 是名词 I am eight years old
eight-year-olds 是名词 表示8岁的一些人，是复数。
the eight-year-old 是名词 表示8岁的一个人，是单数。追问

eight-year-old 不是表示8岁的么？

追答

eight-year-old 不是表示8岁的么？
它是加了连字号的形容词，形容词的话，要修饰个名词，所以要说 I am an eight-year-old boy.那个boy必须要。
eg:I am a thirty-year-old doctor =I am thirty years old .因为year 可数 当名词是要加上s.
而 eight-year-olds 和the eight-year-old 是特殊用法

追问

那可以说eight-year-old when 8岁的时候

追答

那可以说eight-year-old when 8岁的时候

不能，应该说when I was eight years old .or when I was an eight-year-old boy.你那是典型的中式英文。缺主语，缺动词。英语句子最不能少的就是主语和动词。而你的那句话从文法上的结构讲就不正确。
