用法小结
- commit yourself on + 议题：侧重“就某问题表态”（如commit on a policy），
- commit yourself to + 行为/目标：侧重“致力于实现某事”（如commit to reducing pollution）。
例：
He committed himself on the budget plan（就预算计划表态） vs. He committed himself to passing the budget plan（致力于通过预算计划）。
“Commit yourself on”的深层逻辑是“将自身与某议题绑定”，其核心不在于行动的持续性，而在于“立场的公开宣示”。综上所述，该短语常出现在需要“明确责任边界”或“宣示立场”的语境中——无论是政治人物就政策表态，还是伴侣就关系走向承诺，本质上都是通过语言将自身与特定议题的“责任”或“态度”锚定，形成具有社会或情感约束力的声明。
