首先需注意：完整的常用形式是 "raise sb./oneself to one's feet"（易被省略为"raise to one's feet"，但需结合上下文补充逻辑宾语）。
核心含义：
表示“使某人站起来；扶某人起身；（自己）艰难/主动站起来”，强调从“坐、躺、摔倒”等状态到“站立”的动作过程（区别于"stand up"更侧重“状态转换的结果”）。
根据主语与宾语的关系，分两种场景：
结构：主语 + raise + 宾语（sb.） + to + one's feet（"one's"与宾语一致，即“某人的脚”）
例1：The kind stranger raised the elderly woman to her feet after she slipped on the ice.（那位好心的陌生人在老太太冰上滑倒后，把她扶了起来。）
例2：The nurse gently raised the patient to his feet to help him walk.（护士轻轻扶病人起身，帮他走路。）
结构：主语 + raise + oneself + to + one's feet（"oneself"与主语一致，强调“主动/艰难完成动作”）
例1：He raised himself to his feet with great effort after the marathon.（马拉松赛后，他费了很大劲才自己站起来。）
例2：She raised herself to her feet and brushed off her clothes after falling.（摔倒后，她自己站起来，拍了拍衣服。）
结构：sb. + be raised + to + one's feet + by sb.
The injured player was raised to his feet by his teammates.（受伤的球员被队友扶了起来。）
raise to one's feet：更强调动作的“实施过程”（如需要帮助、努力或外力）；
stand up：更侧重“状态转换的结果”（日常口语中更常用，如"Stand up, please."请站起来）；
get to one's feet：与"raise to one's feet"接近，但更口语化，强调“起身”的动作（如"He got to his feet and left."他站起来走了）。
修饰动作难度：with difficulty（艰难地）→ He raised himself to his feet with difficulty.（他艰难地站起来。）
说明动作执行者：by sb.（被某人）→ She was raised to her feet by her friend.（她被朋友扶起来。）
总结："raise to one's feet"是一个强调动作过程的短语，核心是“使（自己/他人）从非站立状态转为站立”，需结合宾语（他人/反身代词）使用，适用于需要外力、努力或描述具体动作的场景。
