常見錯誤

❌I am confident to pass the exam.
✅I am confident that I will pass the exam.' or 'I am confident about passing the exam.
💡confident is not followed by a to-infinitive.
❌She is very confident of herself.
✅She is very confident.' or 'She is very self-confident.
💡confident of is used with outcomes or situations, not people; for self-belief use confident alone or self-confident.
