用法說明
How is "Brain" different from similar structures?What usage mistakes are common with "Brain"?
brain doing vs brain to do
- brain doing 通常用於描述一個正在進行的、具體的思考或分析過程，強調「大腦正在運作」的狀態。
- brain to do 則常用於表示目的、意圖或需要動腦解決的特定任務，結構上常與
need、use、have等動詞連用。 - 在非正式口語中，有時可互換，但細微差別在於：
brain doing更像描述一種持續的腦力活動；brain to do則更像指一個需要動腦的「待辦事項」。 EN: I could see him braining the problem, his brow furrowed in concentration. 翻譯: 我看見他正絞盡腦汁思考那個問題，眉頭緊鎖，全神貫注。
EN:You'll need to brain to solve this final puzzle.
翻譯:你需要動動腦筋才能解開這最後一道謎題。
總結建議

常見錯誤
What are common mistakes with "Brain"?Which "Brain" sentences look correct but are wrong?
×I need to brain the answer.
✓I need to use my brain to find the answer.
"brain" 作為動詞時，意思是「猛擊頭部」或「仔細思考」，並非「用大腦思考」的一般表達。在表示「動腦思考」時，應使用 "use my brain"、"think hard" 或 "rack my brain" 等片語。
×The news was so shocking that it brained me.
✓The news was so shocking that it made my brain freeze.
動詞 "brain" 是及物動詞，需要一個明確的「頭部」作為受詞，且通常指物理上的擊打。它不用來比喻心理或情緒上的衝擊。表達「震驚到無法思考」應使用 "made my brain freeze"、"stunned me" 或 "left me speechless"。
×I was brained by a brilliant idea.
✓A brilliant idea struck me.
動詞 "brain" 的被動式 "be brained" 幾乎只用於字面意義的「頭部被擊中」，不用於比喻「靈光一現」或「想到點子」。表達「突然想到」應使用 "strike"、"occur to" 或 "come up with"。
×This puzzle brains me.
✓This puzzle makes me think hard. / This puzzle is brain-teasing.
動詞 "brain" 沒有「使某人思考」的使役用法。想表達「某事物讓人絞盡腦汁」，應使用 "make someone think"、"puzzle someone"，或使用形容詞 "brain-teasing"、"mind-boggling"。
×I need to brain all these formulas for the test.
✓I need to memorize all these formulas for the test.
"brain" 作為動詞沒有「記憶、背誦」的意思。正確的動詞是 "memorize"、"learn by heart" 或 "commit to memory"。
