幾時用year-old? 幾時用years old?

' year-old' is an adjective, describing people
It is used before a noun
year 一定唔可以有 "s" !!!!

For example: The two-year-old boy is very cute!
兩歲的男孩

' years old' is used after is/am/are

For example: The little boy is two years old.

005似乎是最簡單清楚

year-old is a adj,years old is two words,
e.g
He is an eighty year-old man.
He is eighty years old.
選我吧，我答得最好！

year-old後面有noun, e.g., Sally is a 14-year-old girl.
years old 後面無noun, e.g., Isabella has been a model since she was 12 years old.

how old are you?
你幾多歲?
i am ten years old.
我十歲
問人幾多歲或答人幾多歲的時候就years old

year-old之後一定要係noun.
e.g. I am a 15 year-old girl.

years old 之後可以唔洗跟野
e.g. I am a 15 years old's girl.

希望你明喇!

當你1year~old的時候用year
2~無限years~old的時候用years
