先听一遍
听听‘睡前读书保证提高成绩’如何从较谨慎的研究结果层层演变。
展开英文短文，再悬停查词
Three websites said that reading for ten minutes before bed guaranteed better exam scores. Each linked to another article, and the chain eventually led to a small study about reading habits. The study had not measured exam scores. It had asked participants how they felt about sleep after several evenings.
Our class traced the claim backward and wrote down each change. “May help some people relax” became “improves sleep,” then “raises grades,” and finally “guarantees success.” Every step sounded plausible when read alone. Together, they showed how a cautious result could turn into a promise.
We presented the chain without mocking anyone who had shared the advice. Reading before bed might be pleasant or useful for a particular person. The original study simply could not support the claim about exam scores.
The most valuable word we found was not a technical term. It was “measured.” Once we asked what the researchers had actually measured, the distance between evidence and headline became visible.

三个网站都说，睡前读十分钟书保证考试成绩更好。它们彼此引用，沿链接查到最后，却是一项关于阅读习惯的小研究。研究根本没有测考试分数，只问了参与者几个晚上后对睡眠的感受。
我们班倒着追溯说法，记下每一步的变化：‘可能让部分人放松’变成‘改善睡眠’，再变成‘提高成绩’，最后成了‘保证成功’。单看每一步似乎都说得通，合起来却显示谨慎的结果怎样变成肯定的承诺。
展示这条传播链时，我们没有嘲笑分享建议的人。对某些人而言，睡前阅读确实可能愉快、有用；只是原始研究不能支持提高考试分数的说法。
我们找到最有价值的词，不是什么专业术语，而是‘测量’。一问研究者究竟测了什么，证据与标题之间的距离就清楚了。

背景知识
连续转载会使原本有限的研究发现逐步被夸大。核对原始研究实际测量的指标，是判断标题是否有依据的关键。
