【辨异】forbid和prohibit 都表示禁止做某事。forbid 是常用词，通常指直接的或个人的禁止，如：I forbid you to go. (我不许你去。) 再如：It was useless to forbid children to play in the park. (不许孩子们在公园里玩是没有益处的。) 而prohibit (禁止)是正式用语或法律用语，通常是官方的禁止，如：prohibit the sale of liquor (禁止销售烈性酒)。

【惯用法】forbid 作“禁止”讲时，常用的句型是forbid sb to do sth (禁止某人去做某事)而不说forbid sb from doing it。
