weigh in (on sth.)困难

A federal appeals court weighed in again Tuesday, but instead of providing a badly needed resolution, it only prolonged the fight.

周二，一家联邦上诉法院再次介入，但它非但没有给出急需的解决方案，反而只是延长了这场争斗。

Leading doctors today weigh in on the debate over the government's role in promoting public health by demanding that ministers impose “fat taxes” on unhealthy food and introduce cigarette-style warnings to children about the dangers of a poor diet.

今天，一些顶尖医生加入了关于政府在促进公众健康中应扮演何种角色的辩论，他们要求部长们对不健康食品征收“脂肪税”，并像对香烟那样向儿童发出警示，告诫他们不良饮食的危害。
