题目解答

答案

我们来一步一步地分析这个题目，找出正确答案。

题目内容回顾：

这是一段关于智能手机使用与抑郁症之间关系的研究报告。主要内容包括：

  1. 研究背景：
    研究人员通过跟踪智能手机使用情况（如使用时长、地理位置）发现，高频率的手机使用和静止的地理位置可能与抑郁症有关。

  2. 研究发现：

    • 抑郁症患者平均比非抑郁症患者花更多时间在手机上。
    • 手机使用可能是逃避现实的一种方式，这在抑郁症中常见。
    • 使用手机的地理和使用数据可以以87%的准确率识别抑郁症患者。
    • 相比传统的抑郁症状自评问卷，智能手机数据可能更可靠。

  3. 研究目的：
    探索智能手机是否能作为识别抑郁症的工具。

题目：

What can be learned from the study conducted by researchers at Northwestern University?

选项如下：

  • A. Too much time spent on phones leads to depression
    （花太多时间在手机上会导致抑郁）

  • B. Depressed people tend to spend more time on phones than others
    （抑郁的人比其他人花更多时间在手机上）

  • C. Spending more time on phones can help cure depression
    （花更多时间在手机上有助于治疗抑郁）

  • D. Non-depressed people spend link time on their phones
    （非抑郁的人花链接时间在手机上）——这个选项语义不清，可能是“less time”的笔误。

分析选项：

A. Too much time spent on phones leads to depression

这个选项说的是“手机使用导致抑郁”。但原文并没有明确表示因果关系，而是说“手机使用可能与抑郁有关联”，属于相关性而非因果关系。因此，A 不准确。

B. Depressed people tend to spend more time on phones than others

这个选项说的是“抑郁的人比其他人花更多时间在手机上”。原文中明确提到：“depressed people, on average, spend more time on the phone than non-depressed people.”（抑郁的人平均比非抑郁的人花更多时间在手机上）

这个选项与原文内容完全一致，B 是正确的。

C. Spending more time on phones can help cure depression

这个选项说的是“花更多时间在手机上有助于治疗抑郁”。原文中没有提到手机使用有治疗作用，反而指出它可能是逃避现实的表现。因此，C 是错误的。

D. Non-depressed people spend link time on their phones

这个选项语义不清，可能是“less time”的拼写错误。即使理解为“非抑郁的人花更少时间在手机上”，虽然这在逻辑上可以成立（因为抑郁的人花更多时间），但原文并没有明确说明非抑郁人群的具体使用时间，因此D 不如 B 准确。

结论：

根据研究内容，最准确的选项是：

$\boxed{B}$

解析

考查要点：本题主要考查学生对学术类英文阅读材料的主旨理解和细节辨析能力，需要结合上下文准确提取关键信息，并排除干扰选项。

解题核心思路：

  1. 锁定研究结论：明确文章中 Northwestern University 研究的核心发现（即“抑郁者平均手机使用时间更长”）。
  2. 区分因果与相关性：注意原文仅说明手机使用与抑郁的相关性，而非“手机导致抑郁”的因果关系。
  3. 排除干扰项：选项 C 和 D 均与原文内容无关或表述错误，需通过逻辑分析排除。

关键信息提取：

  • 原文核心结论：
    “Depressed people, on average, spend more time on the phone than non-depressed people.”
    （抑郁者平均手机使用时间更长）
  • 研究目的：通过手机使用数据（如时间、位置）识别抑郁者，准确率高达 87%。

选项分析：

  1. 选项 A（手机使用导致抑郁）：

    • 错误原因：原文仅指出手机使用与抑郁相关，未明确因果关系。
    • 关键句：文中用“linked to depression”而非“causes depression”。

  2. 选项 B（抑郁者手机使用时间更长）：

    • 正确原因：直接对应原文数据，表述完全一致。

  3. 选项 C（手机使用治疗抑郁）：

    • 错误原因：文中未提及治疗作用，反而指出手机使用是“avoidance behavior”（逃避行为）。

  4. 选项 D（非抑郁者使用时间少）：

    • 错误原因：表述混乱（“link time”应为“less time”），且原文未直接比较非抑郁者使用时间。
