英美年龄的说法比较多。大致归纳如下:英美人把人的一生的年龄分为三个时期:1.三十岁前叫做 youth(青少年时期);三十岁至五十岁叫做 theprime of life(壮年时期)。五十岁之后叫做 old age(老年时期)。英美人表示年龄,说一个人多少岁,可只用数量,也可只在数词后加years(year)old 或 year(years)of age 来表示,如:He is forty. The British and American ages have more arguments. It can be roughly summed up as follows: Anglo-American people divide the age of a person’s life into three periods: 1. Before thirty years old, he was called youth (adolescent period); from thirty to fifty years old, he was called the prime of life. After 50 years old, it is called old age. The British and American people express the age, and say how old a person is. They can use only the quantity, or they can only add the years (year) old or year (years) of age after the number, for example: He is forty.
