Some of them are sick, underfed.

他们有的生病, 有的营养不良.

At the earthquake-striken area, people are underfed.

在地震受灾区，人们过着半饥半饱的生活。

In the old days they were underfed and lacking in clothes.

在旧社会他们都缺吃少穿。

His men were idle and dishonest, the fields were full of weeds, the buildings wanted roofing, the hedges were neglected, and the animals were underfed.

他的伙计们也无所事事，这不守职。田地里长满了野草，窝棚顶棚也漏了，树篱无人照管，动物们饥肠辘辘。
