1The Internet may be changing merely what we remember, not our capacity to do so, suggests Columbia University psychology professor Betsy Sparrow.
主干主语：Columbia University psychology professor Betsy Sparrow；谓语：suggests；宾语：The Internet may be changing merely what we remember, not our capacity to do so
结构报道动词 suggests 后置，前面整句是其宾语从句。宾语从句中 The Internet 为主语，may be changing 为谓语，what we remember 为宾语从句作 changing 的宾语；not our capacity to do so 与 what we remember 并列，表对照。merely 限定改变的对象而非能力。专有名词头衔作主语后置，属新闻体倒装。

结构she suggests 为插入语。主句 from...to... 标明 approach 转变的两端。破折号后 something 是对 more conceptual thinking 的补充同位语，其后 that is not available on the Internet 为限制性定语从句。approach to learning 中 to 为介词。
译文她认为，这一趋势或许会改变我们的学习方式：从关注孤立事实与死记硬背，转向更侧重概念性思考——而这恰恰是互联网所无法提供的。

考点wrote 后置的新闻体：先读结论再认作者 · showing that 分词定语 + 宾语从句，evidence 后常接此类结构
