he is [ ] 8 years old boy 他是一个8 岁男孩。一个是用an 还是a？

He is an 8-year-old boy.
an,8-year-old boy，这里连字符连起来的就是一个单词，相当于一个形容词，一个八岁的男孩
这句话有问题。eight-year-old是一个复合形容词，复合形容词在使用时，由数词加名词构成，名词要用单数形式，中间要加一个连字符，可以放在名词前面作定语使用。因为8在英语里读作eight，是元音音素开头，所以前面的不定冠词“一个”要用an，也就是写成：He is an 8-year-old boy.
句子有错 数词与名词组成的复合形容词，用连接符号连接，名词不能加s 。eight/8是元音开头，用 an
正确的是
He is ［an］8-year-old boy.
解答:应为:He is an eight-year-old
boy.他是一个8岁男孩。
