常見錯誤
What are common mistakes with "Important"?Which "Important" sentences look correct but are wrong?
×It is important to me.
✓It is important for me.
使用 'important to' 時，主詞通常是事物或概念，表示對某人來說很重要。使用 'important for' 時，後面常接動詞不定詞（to do something），表示對某人做某事很重要。例如：'This book is important to me.'（這本書對我來說很重要。） vs. 'It is important for me to study.'（對我來說，學習很重要。）
×He is an important person for the company.
✓He is an important person in the company.
描述某人在某個組織、團體或地方內具有重要性時，應使用介系詞 'in'，而不是 'for'。'For' 通常表示目的或對象。
×This is a very important.
✓This is very important. / This is a very important thing.
'Important' 是形容詞，不能直接當作可數名詞使用。它必須修飾一個名詞（如 thing, point, factor），或者單獨作為主詞補語。
×It's important that he comes on time.
✓It's important that he come on time. (美式) / It's important that he should come on time. (英式)
在 'It is important that...' 的句型中，後面的子句通常使用虛擬語氣（美式英語用動詞原形，英式英語常用 'should + 動詞原形'），表示建議或必要性，而非直述事實。
×The most important is health.
✓The most important thing is health.
使用最高級 'the most important' 時，它是一個形容詞片語，後面必須接名詞，或使用 'What is most important is...' 的句型。不能單獨將 'the most important' 當作主詞。
×This meeting is extreme important.
✓This meeting is extremely important.
修飾形容詞 'important' 時，必須使用副詞（如 extremely, very, really），而不是形容詞（如 extreme）。這是常見的詞性混淆錯誤。
