常見錯誤
What are common mistakes with "Clueless"?Which "Clueless" sentences look correct but are wrong?
×He is clueless about how to solve the problem.
✓He has no clue how to solve the problem.
雖然 'clueless' 和 'have no clue' 意思相近，但 'clueless' 通常描述一個人整體的無知或無能狀態，語氣較強且帶有負面評價。'Have no clue' 則較常用於描述對特定事情不知道，語氣較中性。在正式或中性語境中，'have no clue' 更為常見且自然。
×I am clueless to answer this question.
✓I have no clue how to answer this question. / I am clueless about how to answer this question.
'Clueless' 是形容詞，後面不能直接接不定詞 'to answer'。正確用法是接 'about + 名詞/動名詞' 或 'as to + 疑問詞'，或者改用動詞片語 'have no clue' 後接疑問詞引導的子句。
×This manual is clueless.
✓This manual is useless / confusing. / This manual provides no clues.
'Clueless' 主要用於形容「人」無知、一頭霧水的狀態，不用於形容「事物」。形容事物沒有幫助或令人困惑，應使用 'useless', 'unhelpful', 'confusing' 等詞，或使用動詞片語 'provide no clues'。
×She looks cluelessly at the complex diagram.
✓She looks at the complex diagram, completely clueless. / She stares cluelessly at the complex diagram.
'Cluelessly' 是副詞，修飾動詞時，通常描述「以一種茫然、不知所措的方式做某事」，常用動詞如 'stare', 'wander', 'shrug'。'Look' 作為連綴動詞時，後面應接形容詞 'clueless' 描述狀態。原句想表達的是「她看著圖表，一臉茫然」，因此用形容詞更自然。
×I'm sorry, I'm a bit clueless on this topic.
✓I'm sorry, I don't know much about this topic. / I'm not very familiar with this topic.
'Clueless' 語氣非常強烈，意味著「完全無知、一竅不通」，帶有負面評價。在禮貌或謙虛的場合（如會議、課堂），直接說自己 'clueless' 可能顯得不恰當或過於自貶。使用 'I don't know much about...' 或 'I'm not familiar with...' 更為得體且常見。
