age的用法说明 1.

表示年龄，注意以下几组同义句 (后者比前者正式)：How old ishe?＝What’s his age? 他多大年纪? He is ten (years old). ＝Heis ten years of age. 他10岁。He joined the army at (the ageof) 18. ＝ He joined the army when he was 18 (years old). 他18岁参军。2. 英语中表示年老和年轻的习惯与汉语不完全相同： 正：He is very old (young). 　他年纪很大 (小)。误：His age is very old (young). 正：He died at the early age of forty. 他年仅40岁就死了。误：He died at the young age of forty. (虽偶见此用法，但 学生不宜模仿)值得注意的是，old age 和 middle age 却是合符习惯的表达：Who is going to look after them in their old age? 他们年老的时候谁来照顾他们呢? A person of 40 has reached middle age. 一个40岁的人就算已经进入了中年。3. 按英国习惯：(1) 人到了21岁就算成年，并因此引出有下列短语：come of age 达到成年 be over age 过了成年be under age 未到成年be under age (2) 另外，人到了65岁就算步入“老年” (old age)，并因此有相应短语 in (old) age 年老 / with age 因为年老。4. 表示“时期”、“时代”，多用单数形式；表示“很长时间”，可用复数形式也可用单数形式：The 18th century was the goldenage of tt-family: 宋体">世纪是小说的黄金时代。It’s ages [an age] since we last met. 好久不见了。(I) Haven’t seen you for ages[an age]. 好久不见了。
