字面直译是“升至某人的脚（的位置）”，实际表示“站起来；起身”，强调从坐姿、蹲姿或躺姿等状态中“直立起身”的动作。
相比更口语化的"stand up"，"rise to one's feet"更正式、文学化，常用于庄重场合（如仪式、演讲、致敬）或强调动作的过程感（比如缓慢/艰难地站起）。
该短语是动词短语，结构为：
主语是人，"one's"需与主语的人称一致（避免“语法不一致”）；
时态变化：
一般现在时：rise to one's feet（主语为第三人称单数时用rises）；
一般过去时：rose to one's feet；
现在分词：rising to one's feet；
不定式：to rise to one's feet。
通过不同语境的例子，理解其具体用法：

（国歌响起时，所有人起身致敬。）

可通过副词修饰，细化动作的状态：
slowly/gradually rise to one's feet（慢慢/逐渐站起来）；
quickly/suddenly rise to one's feet（迅速/突然站起来）；
struggle to rise to one's feet（挣扎着站起来）；
refuse to rise to one's feet（拒绝站起来）。
"rise to one's feet"是正式的“站起来”表达，适合庄重、文学或需要强调动作过程的场景。记住“主语与人称代词一致”的规则，就能准确使用啦！
