英语短语rest on是一个多义的及物动词短语,核心含义围绕“依托、放置或聚焦”,具体意思需结合语境判断。以下是其最常见的释义、用法及例句:
指某物“放置在…表面上”,主语通常是具体物品,宾语是放置的位置。
The book rests on the desk.(书放在桌子上。)
The vase rested on the shelf for years without being touched.(花瓶在架子上放了好几年没动过。)
表示“依赖某人的支持、帮助或某事物的作用”,相当于depend on/rely on,但更正式。
She rests on her best friend for emotional support during tough times.(她在困难时期依赖闺蜜的情感支持。)

指某观点、理论或决定“基于…(事实/原则)”,相当于be based on,强调“支撑关系”。

His argument rests on the assumption that people act rationally.(他的论点基于“人是理性的”这一假设。)
表示“结果、成败等由…决定”,主语通常是抽象名词(如outcome、success等),宾语是关键因素。

指目光、注意力“集中并停留在某事物上”,强调“聚焦的状态”。

1、 及物属性:后接名词/代词作宾语(不能接从句,若需接从句需用“rest on the fact that…”结构)。
错误:The decision rests on what you say.(需调整为:The decision rests on the fact that you said…)
正确:The decision rests on your words.(决定取决于你的话。)
2、 语态与时态:
通常用主动语态(表示状态或动作),无被动(因“依托”是主动的状态);
时态随语境变化:一般现在时表常态,一般过去时表过去的状态。
3、 同义词替换:
依赖/取决于:depend on、rely on;
以…为基础:be based on、be grounded in;
目光停留:fix on、focus on(但rest on更强调“自然停留”,而非“刻意聚焦”)。
rest on one’s laurels:吃老本(依赖过去的成就,不再努力);
He used to be a top student, but now he’s resting on his laurels.(他以前是优等生,但现在在吃老本。)
rest on one’s shoulders:责任在某人肩上;

综上,rest on的核心是“依托或聚焦于某对象”,从具体的“放置”到抽象的“依赖/基于”,需根据语境灵活理解。
