降重成了刚需,但很多人不会改、改不准、改不学术

这篇文章就来送上:英文学术论文降重公式大全👇

✍️3、扩写重构(Reinforce)

加入限定条件、时间、文献支持,拉开距离

🎯改写案例 3

❌ 原句:AI improves learning efficiency.
✅ 改写:Recent empirical studies (e.g., Smith, 2020) have demonstrated that AI-driven technologies contribute to enhanced learning efficiency, particularly in online learning contexts.

✅ 增加:

四、全段降重实战案例(50% → 6%)

原段落(重复率高)
“The development of artificial intelligence has changed the way people learn. It has become a significant part of modern education, improving learning outcomes and making education more personalized.”

降重后版本(改写+扩写+换词)

  • 领域术语增强(educational methodologies, academic performance

五、英文论文写法小贴士(防止AI痕迹)
