advanced age指“高龄”，old age指“老年”。表达方式at an extremely old age和at a good old age是正确的； He died at an advanced age.（NOT He died at an old age.）He died in his old age.（NOT He died in his advanced age.)
age所在的表达方式when I was of your age，a man of twice my age，of what age he is等中，可省略of；
middle age指“中年”，大概是四十到六十岁，而指“少年”时，常用youth，而不是young age；
不能说My age is young，而是说I am young；
Middle Ages（或the middle ages）指“中世纪”，不可与middle age混用，而old age也不可指“古代”，应用ancient times表示；

n.(名词)age的基本意思是“年龄”“年纪”,引申还可指“长时间”, age还可指具有某种显著特征,或以杰出人物命名的历史时代,也指地质学、考古学中的“时代”。
age表示“年龄”,可用作可数名词或不可数名词,表示“时代”,是可数名词,多用作单数形式,且以大写字母开头。
age笼统指个人或多人的年龄时常用单数。但如果分别指各人的年龄,或age后面跟各个具体的年龄,这时常用复数。
age表示“年龄”“年纪”时,与介词at连用,当表示“时代”“时期”时,与介词in连用,表示“长时间”时,要用介词for,表示“同龄”时,要用介词of, of可省略。
当复数物主代词修饰“年龄”时,可用ages,也可用age。后者着眼于个体。例如:
Array
“他18岁。”的说法:可说He is eighteen.He is eighteen years.He is eighteen years old.He is eighteen years of age.He is aged eighteen.His age is eighteen.不宜说He is eighteen of age.He is of eighteen years old.He is at the age of eighteen.His age is eighteen years old.近年来美国报刊上常有用“age+数词”表示年龄。例如:John Smith, age 17, was arrested for drug-pushing.约翰·史密斯,17岁,因贩毒而被捕。
一般问“你多大年纪?”是How old are you?但也可说What is your age?只是后者是相当正式的语体。
v.(动词)age的基本意思是在不长的时间内“长大,老化,变老” “使苍老”。
age还可指“(酒等)变陈”或“存一段时间再用”,往往表示因历时长久而变好,尤其指味道变醇厚。
age可用作及物动词,也可用作不及物动词。用作及物动词时,接名词或代词作宾语。
age的现在分词有两种形式：ageing和aging,前者更常见些。
age的过去分词可用作前置形容词,表示“…岁的”“年老的”。
