常見錯誤
What are common mistakes with "Crude"?Which "Crude" sentences look correct but are wrong?
×The crude oil price is very high.
✓The price of crude oil is very high.
在英文中，'crude oil' 是一個固定複合名詞，修飾價格時，通常使用 'the price of crude oil' 或 'crude oil prices'（複數）。直接說 'crude oil price' 聽起來不自然。
×His joke was very crude and made everyone laugh.
✓His joke was very crude and made everyone uncomfortable.
'Crude' 形容事物粗糙、未加工，或指言行粗俗、下流、不文雅，帶有負面含義。它通常不會導致歡笑，而是可能引起尷尬或不適。使用時需注意語境與後果的邏輯一致性。
×This is a very crude device, it's very advanced.
✓This is a very crude device, it's very basic.
'Crude' 形容事物簡陋、粗糙、未經精煉，與 'advanced'（先進的）意思完全相反。正確的搭配應是 'basic', 'simple', 'primitive' 等同義或語義連貫的詞。
×She has a crude personality.
✓She has a blunt/rude personality. OR Her manners are crude.
描述人的性格或本質時，較少直接用 'crude'。'Crude' 更常用於描述人的具體行為、言談、舉止或品味（如 crude manners, crude language）。形容性格直率可能用 'blunt' 或 'forthright'；形容粗魯則用 'rude'。
×The data is too crude, we need to make it more detailed.
✓The data is too crude/rough, we need to refine it.
雖然 'make it more detailed' 語意上可通，但與 'crude'（粗糙、未加工）更地道的對應動詞是 'refine'（提煉、精煉）或 'process'。這是一個更精準的搭配。
