【题目】Dr. Ellis regards “scales that focus on the notion of technology ‘addiction’ as
[A] unreliable.
[B]insufficient.
[C] distorted.
[D] unreasonable.
【试题】
①Most studies into the impact of technology use on psychological wellbeing rely on flawed measures. ②Surveys are often used to understand how people use their smartphone, but these are poorly related to actual smartphone use when measured with an app. ③This means that existing evidence suggesting that screen time is “addictive” cannot be used to justify any change of policy.④High smartphone usage has been previously linked to anxiety and depression but Dr Ellis said there is insufficient evidence to support these conclusions: “Scales that focus on the notion of technology ‘addiction’ performed very poorly and were unable to classify people into different groups (e.g, high vs low use) based on their behaviour.”
【参考译文】
①Most studies into the impact of technology use on psychological wellbeing rely on flawed measures. 大多数关于科技使用对心理健康影响的研究都依赖于有缺陷的测量方法。
②Surveys are often used to understand how people use their smartphone, but these are poorly related to actual smartphone use when measured with an app. 通常使用调查的目的是了解人们使用智能手机的方式，但是，当使用app测量时调查与实际智能机使用的相关性很差。
③This means that existing evidence suggesting that screen time is “addictive” cannot be used to justify any change of policy. 这意味着，表明屏幕时间“会让人‘上瘾’”的现有证据不能作为政策改变的理由。
④High smartphone usage has been previously linked to anxiety and depression but Dr Ellis said there is insufficient evidence to support these conclusions: “Scales that focus on the notion of technology ‘addiction’ performed very poorly and were unable to classify people into different groups (e.g, high vs low use) based on their behaviour.”沉溺智能手机以前被认为与焦虑和抑郁有关，但是，Ellis博士说，支持这些结论的证据并不充分：“专注于科技‘上瘾’概念的量表表现非常差，不能把人们根据行为方式分为不同的类别（比如，高使用对低使用）”。
