用英语表示年龄的常用方法:
(1)一般直接用基数词表示,如:
Her daughter is eighteen. 她的女儿18岁。
(2)用“基数词+years old”表示,有时可将years old 换成years of age.如:
Her daughter is eighteen years old. / Her daughter iseighteen years of age. 她的女儿18岁。
(3)用“at the age of +基数词”表示。如:
Her daughter got married at the age of eighteen. 她的女儿18岁就结了婚。
(4)用“基数词-year-old”表示,此结构常做(前置)定语。如:
Her 18-year-old daughter is now in the university. 他18岁的女儿现在上大学。
(5)用“of + 基数词”表示,此结构常做后置定语。如:
Her daughter is now a pretty girl of 18. 她女儿现在一个18岁的美少女了。
(6)用“aged +基数词”表示,此结构常做后置定语。如:
Lying on the floor was a boy aged about seventeen. 躺在地板上的是一个约莫十七岁的男孩。
(7)用“be in one's +几十的复数形式”表示某人大概的年龄。如:
