significantly higher（顯著更高）、significantly better（好得多）。significantly improve（顯著改善）、significantly reduce（大幅減少）。significantly 本身是副詞，後面不接 to do 或 doing 的形式。它修飾的是緊隨其後的詞性。significantly 是強調「狀態/程度」還是「動作/變化」。

翻譯: 新模型的運算速度比舊型號快得多。EN:The new policy will significantly change our daily operations.

significantly vs greatly
「significantly」強調變化或差異的顯著性與重要性，常帶有統計或客觀證據的意味；「greatly」則更通用，主要表示程度高，情感色彩較強。
significantly vs considerably
兩者皆可表示「相當地、顯著地」，但「significantly」更強調變化或差異具有重要意義或影響；「considerably」則側重於數量或程度上的「相當大」，語意稍弱。
significantly vs markedly
「significantly」與「markedly」都表示明顯的變化，但「markedly」更強調變化清晰可見、易於察覺，常用於描述狀態的對比；「significantly」則更常與重要性或影響力連結。

×The results showed a significant increase. (using adjective when adverb is needed)
✓The results increased significantly.
"Significant" 是形容詞，修飾名詞；"significantly" 是副詞，修飾動詞、形容詞或其他副詞。當要描述動作或變化的程度時，應使用副詞形式。
×He significantly contributed to the project success.
✓He contributed significantly to the project's success.
副詞 "significantly" 通常不直接放在主要動詞之前，除非是助動詞結構（如 "has significantly improved"）。在簡單動詞時，常置於動詞後或句尾以聽起來更自然。
×The test scores improved very significantly.
✓The test scores improved significantly.
"Significantly" 本身已表示「顯著地、相當大地」，通常不需要再用 "very" 來加強。使用 "very significantly" 雖然文法正確，但在多數正式寫作中被視為冗餘。
×This model is significantly better than that one. (缺少比較對象或語境不清)
✓This model performs significantly better than the old one in speed tests.
使用 "significantly" 進行比較時，必須清楚說明比較的對象和方面，否則語意會不夠完整。
×The room was significantly empty.
✓The room was almost completely empty.
"Significantly" 通常與可分級的形容詞或動詞（如 increase, improve, different, higher）連用，表示程度上的顯著差異。它不與非分級形容詞（如 empty, dead, unique）連用，因為這些詞本身已是絕對狀態。
