老师如何一眼看出论文的AI痕迹？

AI改出的论文真的很让老师抓狂！一眼就被识破分数低又不安全。

老师如何一眼看出论文AI痕迹？

今日为大家科普:

1、含糊或重复的表述

AI 往往依赖一些听起来还行、但并不增添实质内容的通用表述。它可能过度使用某些术语和观点，却没有新的洞见。

Student Writing:“In my school, we’ve started using technology to enhance learning. I’ve noticed that students are more engaged when they use tablets to work on assignments, especially in science class.”

AI Writing:

“Technology is changing the world. It is having an impact on people’s lives. Many industries are using technology to change how they work.”

学生版本更具体、与个人经验相关；而 AI 版本只是重复模糊的概念。反复使用含糊的短语，例如“社会在变化”“科技很重要”等，但不提供新的信息。

2、缺乏个人洞见或原创观点

AI 能总结、报告事实，但很难像学生一样提供个人洞见或独特视角。AI 生成的文章往往千篇一律，缺少与主题的个人联结。

Student Writing:“I attended a local climate change rally last month, and seeing so many people passionate about making a difference really opened my eyes. It made me want to do more for the environment.”AI Writing:

“Climate change is a pressing global issue. Many people have joined movements to combat it. These movements are helping to raise awareness.”

学生版扎根于个人经验；AI 版只停留在事实层面，缺乏个性或批判性思考, 没有个人性或独特性。

3、信息古怪或不正确

AI写作速度快，但并不总是事实正确。它从各处抓取信息而缺乏理解，细节可能错误甚至臆造。For example:“Albert Einstein invented the telephone.”显然错误，电话是亚历山大·格拉汉姆·贝尔发明的。若有历史混淆或技术性错误，可能源于 AI 对语境理解不足。

4、行文生硬或缺乏连贯性

Student Writing: “Technology has completely transformed how I communicate. Smartphones, in particular, have become an essential part of my daily life. They help me stay connected with my family and keep up with work, no matter where I am. For instance, I use my smartphone to manage my calendar, chat with friends, and even shop for groceries”

AI Writing:

“The evolution of technology has changed communication. The impact of smartphones is clear. They have become an essential part of our daily lives. People use them to stay connected, work, and shop. It is changing the world.”

学生版逻辑更连贯；AI 版显得松散。观点或话题突然转折、缺少解释。句与段之间过渡不自然。

5、过度使用复杂或正式的语言

AI常依赖大词和复杂句来显得更专业。即使用更简单的语言就能表达清楚，AI也可能偏好“华丽说法”。

Student Writing: “Technology has had a big impact on society, and it changes how we communicate with each other.”AI Writing: “Theproliferationof technological innovations has had aprofoundeffect on society,fundamentallyaltering the way individuals interact with one another.”

学生版更清晰易读；AI版显得过于正式, “好听但不贴切”的词语，像是从别处生搬硬套。

6、句式重复

AI容易反复使用同一种句式，不善于像人类那样自然地变化结构。如果句子结构一成不变或过度依赖连接词，可能是 AI生成。

Student Writing:“Climate change is one of the most pressing issues we face today. It’s having an impact on everything from the environment to our daily lives. If we don’t take action, the consequences will be even more severe.”AI Writing:“Climate change is a global issue. It affects the environment. It has serious consequences. It impacts people’s lives.”AI版像“复读机”, 句子彼此之间缺乏变化，读来单调。学生版句式更丰富、信息更充实。

7、分析流于表面

AI能提供大量信息，但常缺乏深入分析或原创见解。它擅长总结，却容易停留在表面。AI版：Globalisation has reshaped education by broadening perspectives.评论：Example? Which uni? Which course?学生版："In XX university, globalization is obvious because many courses now include case studies from other countries."In XX university, the policy added case studiesfrom Asia in EDU101 since 2023; survey (n=124) shows 68% report broader perspectives.AI空泛的概述，没有深挖, 缺少对不同观点的评估或批判性思考。

8、捏造reference

AI writing:While AI tools can be valuable resources, they shouldn’t replace genuine learning or original thought (Alberth, 2023). By looking for signs like vague phrasing, lack of personal insight, and incorrect details, you can spot when AI might have been used (Lee, 2025)全网根本找不到(Lee, 2025) ，甚至混合真实的reference（比如Alberth, 2023）和虚假的reference (比如Lee, 2025) 。
