常見錯誤
What are common mistakes with "Careful"?Which "Careful" sentences look correct but are wrong?
×Be careful to not fall.
✓Be careful not to fall.
在 'careful' 後，正確的否定形式是 'not to + 動詞'，而不是 'to not + 動詞'。
×You should be careful for your health.
✓You should be careful about/of your health.
表達「對...小心/注意」時，常用介系詞 'about' 或 'of'，而不是 'for'。'For' 通常表示目的或原因。
×He is a careful driver, isn't it?
✓He is a careful driver, isn't he?
附加問句的主詞和動詞必須與主要子句一致。主要子句主詞是 'He'，所以附加問句應使用 'isn't he?'，而不是 'isn't it?'。
×Please drive careful.
✓Please drive carefully.
動詞 'drive' 需要副詞來修飾其方式。'Careful' 是形容詞，應用副詞形式 'carefully'。
×I am careful to do my homework.
✓I am careful when doing my homework. / I am careful to do my homework correctly.
'Be careful to do something' 通常暗示「確保去做某事」或「小心地以正確方式做某事」，而非單純描述在做某事的狀態。若要描述在做某事的當下很小心，更自然的說法是 'be careful when doing...' 或使用副詞。原句語意不清。
×He is more careful than her.
✓He is more careful than she (is).
在正式文法中，比較級後方若省略動詞，應使用主格代名詞（如 she, he, I）。口語中 'than her' 雖常見，但在書寫或正式場合，'than she (is)' 被認為更正確。
