问题 By the end of 2018, more than______of the global population will be using a smart phone.
  
Nearly 2. 4 billion people around the world used a smart phone in 2017. By the end of 2018, more than a third of the global population will be using a smart phone.
   On the one hand, it sends us unlimited amounts of information. We don’t have to wait. Our devices ring, ping, vibrate and light up with the latest news from family, friends and around the world.
   On the other hand, this immediate access to information may become an addiction. And it may make some people feel lonely, anxious and depressed. These findings are from a 2018 study from San Francisco State University and have been published in Neuro Regulation.
   Erik Peper and Richard Harvey are both health education professors at the university. They led the study. In a statement to the press, the two professors claim that "overuse of smart phones is just like any other type of substance abuse. " Also, addiction to social media may affect our emotional state.
   The two professors asked 135 university students about their smart phone use and their feelings. They found that "students who used their phones the most reported higher levels of feeling . . . lonely, depressed and anxious. "
   But the researchers also suggest ways to fight back. They say that we can train our brains to be less addicted to our phones and computers. Erik Peper suggests turning off push notifications and other such alerts on our phones. More often than not, our devices share unimportant information as if our lives depended on it. Our brains see the notices the same way. And that is a problem. So, just turn them off.
   The researchers also suggest taking control of when and where you answer a text or email. You do not need to answer them all. And you certainly don’t need to answer them as soon as you get them.
   They also suggest setting limits on the time you spend on social media. If you want to catch up with friends on Facebook, set aside a small amount of time to it. Schedule periods of the day to focus on important tasks and do not allow technology to interfere.

选项 A、Positive.
B、Objective.
C、Negative.
D、Uncertain.

答案B

解析 观点态度的推理与判断。本题干的问题是“文章中研究人员对使用智能手机持什么态度”,虽然问的是观点态度,但实际上是要求学生把握文章的主旨大意,在这基础上合理推断选择。我们可以将原文的关键信息整合为“越来越多的人使用智能手机。一方面,它提供给我们无限数量的信息。另一方面,这种即时获取信息的方式可能会让人上瘾。旧金山州立大学(San Francisco State University)的健康教育教授埃里克-佩珀(Erik Peper)和理查德-哈维(Richard Harvey)领导了一项研究,他们发现过度使用智能手机就像滥用其他类型的药物一样。但研究人员也提出了反击的方法。他们建议关闭手机上的推送通知和其他类似的提醒,控制何时何地回复短信或电子邮件,限制在社交媒体上花费的时间”。通过对这些主要信息的理解和判断,我们可以发现现实生活中存在过度使用智能手机这一现象,所以不能选择A选项“对智能手机的使用持积极态度”;同时研究者针对过度使用手机这一现象提出了三点建议,以此来帮助人们克服过度依赖智能手机的问题,由此排除C选项“对智能手机的使用持消极态度”;研究者虽然没有明确说明自己的态度,但是可以从文中信息进行合理的推断,所以D选项“对智能手机的使用态度不确定”可以排除;结合以上分析,可以发现选项B“对智能手机的使用持客观态度”是基于原文的合理判断,研究者既说明了现状,又提出了应对策略,建议人们正确合理使用智能手机,所以正确选项为B。
