tie up(短语动词)常见含义:
/taɪ ʌp/
Please tie up the bag so nothing falls out.
请把袋子系紧,别让东西掉出来。
Before we leave, we need to tie up a few loose ends and confirm the schedule with everyone involved.
出发前,我们得把一些未了事项收尾,并与所有相关人员确认日程。
tie 源自古英语 tīegan,有“系、绑、捆”的意思;加上副词 up(表示“向上/封住/完成”),构成短语动词 tie up,最初侧重“系牢、固定”,后来语义引申到“把事情收尾”“忙得脱不开身”等更抽象的用法。
