seven-year-olds 是什么意思

seven-year-old 的汉语意思:7岁大或7岁了...... 恕我直言。。楼主打出来的句子是病句。。。 (old后面不应该+s) seven years old 与seven-year-old 的区别 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
