用法筆記

Only used with third-person singular subjects: he, she, it, or a singular noun (e.g. 'the teacher', 'my sister', 'the computer'). For first-person (I, we), second-person (you), third-person plural (they), and plural nouns, use the base form 'do' instead. In questions and negatives, 'does' carries the third-person -s and the main verb remains in its base form: 'Does she walk to school?' — not 'Does she walks to school?'

常見錯誤

❌He do his homework every day.
✅He does his homework every day.
💡Third-person singular subjects require 'does', not 'do'.
❌She does not likes coffee.
✅She does not like coffee.
💡After 'does not', the main verb stays in its base form without -s.
❌Does she walks to school?
✅Does she walk to school?
💡In questions, 'does' already carries the third-person -s, so the main verb uses the base form.
