常見錯誤
What are common mistakes with "Blue"?Which "Blue" sentences look correct but are wrong?

✓He blued the wall yesterday.
動詞 "blue" 的過去式是規則變化，應在詞尾加 "-d" 或 "-ed"，而非直接使用原形。
×The sky blues.
✓The sky turns blue.
"blue" 作為動詞時，意思是「使變藍」或「染藍」，通常需要一個施動者（人或化學過程）來執行這個動作。描述天空自然變藍，應使用 "turn blue" 或 "become blue"。
×I want to blue my room.
✓I want to paint my room blue.
雖然 "blue" 可作動詞，但在口語中更常使用 "paint something blue" 來表達「將某物漆成藍色」。直接使用 "blue" 作動詞聽起來較為技術性或古老。
×The artist is blueing the painting now.
✓The artist is adding blue to the painting now.
"blue" 作為動詞（染色）通常不用於進行式來描述正在進行的著色動作，聽起來不自然。應使用更具體的動詞，如 "adding blue", "applying blue", 或 "coloring blue"。
×He blued all his money on gambling. (intending to mean 'spent')
✓He blew all his money on gambling.
這是常見的同音字混淆。"Blue"（使變藍）和 "blew"（blow 的過去式，意為「吹」或俚語「揮霍」）發音相同。表達「花光、揮霍」金錢時，應使用 "blow - blew - blown"。
