考官的英文是"examiner"。这个词来源于拉丁语"examinare"，意思是"to test"或"to inquire into". 例如：

The examiner asked the candidate to solve the math problem on the board. (考官让考生解决黑板上的数学题。)

The examiner will grade your performance on the driving test. (考官会对你的驾照考试表现进行评分。)

另外，考官也可以用"proctor"表示，它来源于拉丁语"procurare"，意思是"to take care of"或"to manage". 例如：

The proctor will distribute the exam papers. (监考员会发放考卷。)

The proctor will ensure that the test is conducted fairly. (监考员会确保考试公平进行。)
