Put your foot down 表示态度坚决：明确禁止某件事，或坚持要求。常用来描述父母、上司或邻居忍耐很久后终于表示“够了”。在英式英语中，它还有另一个意思：踩下油门，加快车速。这个习语对正式作文来说过于口语化，可以改用 take a firm stand。

修改原因
修改前When my flatmate started inviting friends over every night, I put my leg down.
修改后When my flatmate started inviting friends over every night, I put my foot down.
有些语言用同一个词表示 leg 和 foot，所以容易误写成 put my leg down。但这个习语使用 foot，即能稳稳踩在地上的脚。换成 leg，就失去了比喻义，听起来像在描述一个身体动作。修正把 leg 换成了 foot。
开车时，put your foot down 可以表示加速：We're late, put your foot down! 具体意思由上下文决定：谈的是汽车和速度，指踩油门；谈的是规则和禁止，指态度坚决。
