散步的猫撒
ages 3 to 17是后置定语，修饰前面的名词people，但是语法是错误的，应该是aged，过去分词做定语，不可能是ages三单形式，因为这个句子的主语是Sinopharm's COVID-19 vaccine（国药控股COVID-19疫苗），谓语是has been approved。一个句子不会出现俩个谓语，何况for young people是介宾短语，也不是句子。说说age的用法。age， /eɪdʒ/ 。单音节单词n. 年龄；时代；寿命，使用年限；阶段; vi. 成熟；变老; vt. 使成熟；使变老，上年纪。aged，adj. 年老的；…岁的；老年人特有的; v. 老化（age的过去式）She's long past retirement age. （名词）她早已超过了退休年龄。The group is of all ages. （名词的复数）这个小组各种年龄的人都有。The camp is for youngsters aged 8 to 14. （动词的过去分词做后置定语）这次夏令营是为8至14岁的少年儿童安排的。They have two children aged six and nine. （动词的过去分词做后置定语）他们有两个小孩，一个六岁，一个九岁。

有关年龄的英文表达方式有：1、直接表达：主语+be动词+具体数字. 例：He is thirty．他30岁。2、主语+be动词+具体数字+years old. He is thirty years old．他30岁。
(1) 一般直接用基数词表示：
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：
Her daughter is eighteen years old. / Her daughter is eighteen years of age. 她的女儿18岁。

估计题主提供的这段英文来自China Daily或其它国内英文报刊，它们出错是常有的事。前面网友“唐娜杨”说的对，其中的ages错了，应该是aged.这里young people aged 3 to 17的意思是“年龄在3到17岁的青少年”，其中的aged 3 to 17作young people的后置定语。
