seven years old和even-year-old的区别

Answer 1

1.seven years old 可做谓语,不可以做冠词 就是不可以用来修饰名词代词等 但even-year-old可以 。比如:she is a seven-year-old girl 此处的even-year-old不可用seven years old代替
2.seven-year-old 简单来说是一个形容词性词组,可用于修饰名词代词等词语,但不可单独做谓语 就是说不可以在 其后没有名词代词等词语的时候 单用 而seven years old可以 比如 she is seven years old.而不可以说she is seven-year-old
