unwearying

1. Women, their arms folded over their coarse aprons, standing gossiping at the end of their block, stared after the Brangwen sisters with that long, unwearying stare of aborigines;
   女人们戴着围裙，双臂交叉着抱在胸前，站在远处窃窃私语，她们用一种不开化人的目光目不转睛地盯着布朗温姐妹；
2. But since in reality Big Brother is not omnipotent and the party is not infallible, there is need for an unwearying, moment-to-moment flexibility in the treatment of facts.
   这就需要在处理事实时要始终不懈地、时时刻刻地保持灵活性。

adj

1. showing sustained enthusiastic action with unflagging vitality
