问职业用 What does he/she do?（他/她是做什么的？）；问工作地点用 Where does he/she work?（他/她在哪工作？）。 注意第三人称单数：does 后面动词用原形（do, work），回答时动词要加 s：He works in a hospital. driver 是 drive 去 e 加 r；farmer、worker 直接加 -er。
问"在哪工作"用 Where does she work? → 回答：She works in a hospital.
第 3 步 · 注意单三
does 后动词用原形（do, work）；回答主语是 she，动词要加 s：works。
✅ 结论：What does she do? — She is a nurse. Where does she work? — She works in a hospital. 口诀：问职业 What does ... do，问地点 Where does ... work；does 后用原形，回答动词加 s。
