这是个好问题!这两个词看起来很相似。 Does表示药物的单剂量, dosage表示药物的推荐剂量。示例: I'll take my next dose of medicine at lunchtime. (下一粒药将在午餐时服用。) 示例: The recommended dosage is two tablets every four hours. (推荐剂量为每 4 小时 2 片。) 例: The doctor recommended the dosage of a tablet in the morning and a tablet at night. I just took the first dose in the morning. (医生建议早上1片,晚上1片。我早上刚吃1片。)
