形容词可以修饰形容词吗(With the young unable to afford to leave home...)

With the youngunable to afford to leave home and the old at risk of isolation, more familiesare choosing to live together.

这个句子有点奇怪，如何会用形容词修饰形容词呢？

这里的 the young 已用作名词（意思是“青年”），与 the old, the rich, thepoor 等用作名词的使用方法一样。同时注意后面的 the old 也用作名词。本句涉及 with 复合结构（with+名词+形容词），表缘由。句子大意为：

With the young unable to afford to leave home and the old at risk of isolation, morefamilies are choosing to live together.

因为青年负担不起离家分居的成本，同时老人又有承受孤独的风险，所以更多的家庭选择住在一块。
