用法筆記

Only the past-tense form of 'know'. The base form 'know' is used for present and general truths; 'knew' refers exclusively to a past time. Unlike regular past-tense verbs, 'knew' does not take an -ed ending.

❌Yesterday I know the answer.
✅Yesterday I knew the answer.
💡Use 'knew' for past time, not the present-tense 'know'.
❌She has knew him since 2010.
✅She has known him since 2010.
💡After 'has' or 'have', use the past participle 'known', not the past simple 'knew'.
