形容詞可以修飾形容詞嗎(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.

這個句子有點奇怪，如何會用形容詞修飾形容詞呢？

這里的 the young 已用作名詞（意思是“青年”），與 the old, the rich, thepoor 等用作名詞的使用方法一樣。同時注意后面的 the old 也用作名詞。本句涉及 with 復合結構（with+名詞+形容詞），表緣由。句子大意為：

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

因為青年負擔不起離家分居的成本，同時老人又有承受孤獨的風險，所以更多的家庭選擇住在一塊。
