当 ChatGPT 被要求“总结一段文字”时，它根本没在“总结”。

No really: ChatGPT doesn’t summarise. When I asked ChatGPT to summarise this text, it instead shortened the text. And there is a fundamental difference between the two. To summarise, you need to understand what the paper is saying. To shorten text, not so much. To truly summarise, you need to be able to detect that from 40 sentences, 35 are leading up to the 36th, 4 follow it with some additional remarks, but it is that 36th that is essential for the summary and that without that 36th, the content is lost.
作者要求 ChatGPT “总结”一篇文献时， ChatGPT 看起来是生成了一段总结，但它其实只是缩短了句子。
要“总计一段文献”，你需要对这段文献在讲什么有充分的了解，你需要发现这40句话里，最重要的是第36句，前35句是引语，后四句跟进了一些额外的评论，但最重要的是第36句所说的内容必须被包含在你的总结里。没有这些内容，文献的主干就丢了。

ChatGPT就完全没有把主干内容加进去。
