正式寫作注意：在正式或學術寫作中，應避免使用口語中常見的填充停頓（如「uh」、「well」引導的句子），並使用更精確的詞彙（如「enhancement」、「advancement」、「refinement」）來替代重複出現的「improvement」，以使文體更嚴謹。

常見錯誤
What are common mistakes with "Improvement"?Which "Improvement" sentences look correct but are wrong?
×There is an improvement of the situation.
✓There is an improvement in the situation.
使用 'improvement' 時，表示在某個領域或方面有進步，通常搭配介系詞 'in'，而不是 'of'。'of' 多用於表示所屬關係或內容。
×He made an improvement on his English skills.
✓He made an improvement in his English skills.
表示在技能、能力或某個抽象領域有進步時，應使用 'improvement in'。'Improvement on' 通常用於比較兩個具體事物，表示後者比前者更好，例如 'This design is an improvement on the previous one.'。
×We need to do an improvement to the system.
✓We need to make an improvement to the system.
與 'improvement' 搭配的動詞通常是 'make' 或 'see/show'，而不是 'do'。'Make an improvement' 表示主動進行改善，'see/show improvement' 表示觀察到或展現出進步。
×There is still room of improvement.
✓There is still room for improvement.
固定片語 'room for improvement' 表示「有改進的空間」，必須使用介系詞 'for'，不可用 'of'。
×I hope a quick improvement.
✓I hope for a quick improvement. / I hope to see a quick improvement.
'Hope' 作為動詞時，若後面接名詞（如 improvement），通常需要搭配介系詞 'for'（hope for something），或使用不定詞片語（hope to see/achieve something）。直接接名詞是錯誤的。
×It's a big improvement than before.
✓It's a big improvement over before. / It's a big improvement compared to before.
表示「與...相比有所改善」時，'improvement' 後應接 'over' 或 'compared to'，而不是 'than'。'Than' 主要用於形容詞或副詞的比較級（如 better than）。
