怎样区别forty-years-old 和forty years old

来源：百度知道编辑：UC知道时间：2024/05/29 20:29:36

有哪位朋友可以告诉我,forty-years-old 和forty years old的区别,用法.顺便举几个列子

前者一般做定语，后面要跟上名词，比如a forty-year-old man.（你打错了，这里的year后面不能加s），当然，老外有时候也会把这结构直接当名词用，后面那个名词省略，比如 a forty-year-old，就是指一个四十岁的人，性别不详。（这种形式一般中学考试里不会见到）

forty years old只能做表语了，不能做定语。比如He is forty years old.

为什么会在上面的答案里看到50岁～明明是40
forty-years-old 应该是forty-year-old ，它是做定语来用,相当于形容词40岁的。
例如，He is a forty-years-old man.

forty years old是做表语，一般前面加be动词。
例如，He is forty years old.

forty-year-old吧？不是forty-years-old

forty-year-old是个形容词，50岁的……a forty-year-old man.
forty years old是说50岁了，he is forty years old

希望可以帮到你- -

其实就是50岁的意思

只是两中不同的格式

对了那个因该是FORTY-YEAR-OLD

forty-years-old是形容词，forty years old是句子的一部分。
she is a forty-years-old lady.
she is forty years old.
