该短语的主语通常是医生、外科医生(surgeon)或医疗团队,宾语可以是人或身体部位,强调“对目标对象进行手术操作”。
The surgeon will operate on the patient tomorrow.
外科医生明天会给这个病人做手术。
They had to operate on his broken arm to set the bones.
他们不得不给他骨折的手臂做手术来固定骨头。
用介词 for 引出“做手术的病因或目的”:
The doctor operated on her for appendicitis (阑尾炎).
医生因为阑尾炎给她做了手术。
He was operated on for a brain tumor last month.
他上个月因为脑瘤做了手术。
当强调“病人被手术”时,用被动结构(注意不要漏掉 on):
The old man was operated on successfully yesterday.
这位老人昨天手术很成功。
She has already been operated on twice for her knee problem.
她因膝盖问题已经做过两次手术了。
不能省略介词 on:“operate”作“手术”讲时是不及物动词,必须加 on 才能接宾语(人/部位)。
✖ 错误:The doctor will operate the patient.
✔ 正确:The doctor will operate on the patient.
在非医疗场景中,operate on 偶尔可表示“对……起作用/影响”(类似“work on”),但这种用法不常用:
The new policy operates on small businesses in a positive way.
新政策对小企业产生了积极影响。
