先听一遍
听听小组为什么没有直接采用 AI 给出的车站开通年份。

For a local history project, I asked an AI tool when our old station opened. It gave me a clear year and a long explanation. I was ready to put the answer in my slides, but my friend asked, “Where did that date come from?”
The tool had not shown a source. We checked the town library's digital archive and found a photograph with a different date. Then we looked at a page from the station's own history book. It explained that the building had opened in one year and the train service had begun in another.
The AI's answer had sounded certain, but it had mixed two events. Our final slide included both dates and named the sources we used.

读懂了什么？
读完后，试着用一句话说出本文的主要意思，并从原文找出支持它的一句话。
查看中文译文
做地方史项目时，我问一个 AI 工具，我们的老车站是哪一年开通的。它给出了明确的年份，还附上一大段解释。我正准备把答案放进幻灯片，朋友却问：‘这个日期是从哪里来的？’
工具没有列出来源。我们查阅镇图书馆的数字档案，找到一张标着不同日期的照片。接着，我们又看了车站自身的历史资料。其中解释说，车站建筑是在一年落成的，列车服务则是在另一年开始的。
AI 的回答听起来很肯定，却把两件事混在了一起。最后一页幻灯片写明了两个日期，也注明了我们用到的资料来源。
