用法筆記

Unlike most English verbs, 'see' has an irregular past participle: 'seen' (not 'seed' or 'sawed'). Do not confuse 'seen' with the simple past form 'saw' — you must use a helping verb (have/has/had/be) with 'seen'.

常見錯誤

❌I seen that movie yesterday.
✅I saw that movie yesterday.
💡'seen' must be paired with a form of 'have' or 'be'; use 'saw' alone for simple past.
❌She has saw the results already.
✅She has seen the results already.
💡'saw' is the simple past form; 'seen' is the past participle and must follow 'have/has/had'.
