bound的相关用法：
adj.(形容词)
1）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。
2）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。
3）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??”。
bound的英式读法是[baʊnd]；美式读法是[baʊnd]。作形容词意思是必定的；有义务的；受约束的；装订的。作不及物动词意思是跳；跳跃前进；猛涨。作名词意思是跳跃；范围；界限。
bound up in意思就是忙于某事的，热衷于某事物的，和very busy with sth是同义词。
相关例句：
1、He is bound up in his work these days.
这些天他在忙于自己的工作。
2、Polly came bounding into the room holding a letter.

词义辨析：
n.(名词)
1）bound, frontier
这两个词都指“分界线”。frontier指一个国家邻近另一个国家边境的领土或未开发的地区、领域; bound可指国家、地区等的“边界”,也可指思想领域、法律、科学界等的“界线”“限制”“限制范围”。
2）bounds, border, boundary, limit
这组词都有“疆界”“边境”“界限”的意思。
与boundary和border相比, limit是最普通用词，含意较广，可用于任何最外面的限度、范围、分界等:bounds通常表示的不是看得见的边界(线),而是用于比喻意义,指人的行为。
boundary主要用来指领土，尤其是地图上表示的边界、分界线，也可用来比喻知识、欲望等抽象事物的界限：border通常强调两个地区之间的边境,指沿分界线一带的土地。
