“变成粉末的”可以用英语表达为 “powdered” 或 “reduced to powder”(后者更强调变成粉末这一动作或结果的状态)。具体使用可根据语境选择:
Powdered:作为形容词,直接描述物体已变成粉末的状态,例如:
The medication came in powdered form.(这种药是粉末状的。)
We use powdered sugar for decorating cakes.(我们用糖粉装饰蛋糕。)
Reduced to powder:作为短语动词,强调“被粉碎成粉末”的动作或结果,例如:
The rock was reduced to powder by the explosion.(爆炸将岩石炸成了粉末。)
The ancient ruins were slowly eroded until they were reduced to powder.(古迹逐渐风化,最终变成了粉末。)
根据语境,若需简洁描述状态,用 powdered;若需强调动作或结果,用 reduced to powder。
