I turned around to find a frail, elderly woman dressed in flowing white robes.

我转身发现一位身穿飘逸白袍的年迈体弱的妇女。

A few frail elderly people sat in long chairs on the porches with rugs tucked around them.

几个虚弱的老人坐在门廊的长椅上， 周围盖着地毯。

For example, groups that can’t work, like children, the severely disabled, and the frail elderly, are particularly vulnerable to poverty.

例如，无法工作的群体，如儿童、重度残疾人和体弱的老人，特别容易陷入贫困。
