我去监考了英文怎么说

你可以说 "I invigilated an Engpsh exam." 或 "I was an invigilator for an Engpsh exam."

"Invigilate" 是一个英文动词，意思是监考或监督考试。这个词来自拉丁文 "vigilare"，意思是保持警惕或注意力集中。

例句：

I invigilated the final exams for the Engpsh course last week. (我上周监考了英语课的期末考试。)
As an invigilator, it's my job to make sure the students follow the rules during the exam. (作为监考人员，我的工作就是确保学生在考试期间遵守规则。)
The invigilator will be checking IDs at the door before the exam. (监考人员会在考试前在门口检查身份证。)
