用法辨析

v. (动词)

• bound用作动词作“跳跃”解时,指水平向前地、快速连续地跳跃,强调由此获得的冲力,暗含精神上的轻松与活力之意。

adj. (形容词)

• bound用作形容词时与bind的过去分词同形,基本意思是“被捆绑的,被束缚的”,常引申表示“受约束的”“有义务的”,指有法律责任或有义务做某事
• bound还可作“一定的,必定的”“去,准备去”解,只用作表语。作“一定的,必定的”解时,其后常接动词不定式，不跟to短语；作“去；准备去”解时常跟for短语表示目的地。
• bound后可接不定式，原在英国表示“将不得不……”，在美国表示“决意……”解。如今，两国人都将其解释为“一定将……”。It is bound to rain. 一定将会下雨。
• 表示开往某地，仅有目的地时，用be bound for,后接目的地。表示从某地开往某地，出发地和目的地都有时，用be bound from...to...。The ship is bound from Qingdao to Shanghai. 这艘船是从青岛开往上海。
• 在表示“范围”，作名词时，bound要用其复数形式bounds。
