八岁男孩用英语怎么说

八岁男孩用英语怎么说

都对

You say the boy is eight years old. And you say he is a eight-year-old boy. This pattern goes all the way back to Old English (alias Anglo-Saxon). It's the same reason many of us say that someone is "5 foot 2" rather than "5 feet 2".

都对,但有时要看情景.

一个八岁的男孩： an eight-year-old boy a boy of eight (years old)

1.对。用2 应是 The boy is eight years old
