Question

    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 smart phones. Those numbers sound great, don't they? More people will have more information at their fingertips. However, smart phone technology can be a double-edged sword（双刃剑）.

On one hand, it sends us endless information. We don't have to wait. Our devices ring, vibrate（振动）and light up with the latest news from family, friends and around the world. On the other hand, this immediate way to information may become an addiction（瘾）. And it may make some people feel lonely, worried and stressed.

These findings are from a 2018 study from Erik Peper and Richard Harvey who are both health education teachers at San Francisco State University. They led the study.

The two teachers 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, stressed and worried."

But Erik Peper suggests turning off push notifications（推送提醒）and other such alerts on our phones. The researchers also suggest taking control of when and where you answer a text, a message or an 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 smart phones. If you want to catch up with friends, set aside a small amount of time to it. Focus on important tasks and do not allow technology to take up your time.

【解析】

在2017年全世界范围内使用智能手机人数达到了24亿，截止2018年，将会有超过三分之一的全世界人口使用智能手机。智能手机在我们生活中非常重要，但是它也是一把双刃剑。根据调查，使用智能手机的学生更容易出现孤单、压力大和焦虑。所以作者建议，用手机一定要有限度，不要让现代科技占用你太多时间。

1.细节理解题。根据“By the end of 2018, more than a third of the global population will be using smart phones.”可知截止2018年，将会有超过三分之一的全世界人口使用智能手机。故选D。

2.细节理解题。根据“On the other hand, this immediate way to information may become an addiction（瘾）. And it may make some people feel lonely, worried and stressed. ”可知直接、立刻回短信的方式会让人感觉孤单、压力大和焦虑。故选D。

3.细节理解题。根据“These findings are from a 2018 study from Erik Peper and Richard Harvey who are both health education teachers at San Francisco State University.”可知Erik Peper和Richard Harvey是旧金山州立大学的健康教育老师。故选B。

4.推理判断题。文章最后一段是Erik Peter提出的建议，其中有“But Erik Peper suggests turning off push notifications（推送提醒）and other such alerts on our phones.”“The researchers also suggest taking control of when and where you answer a text, a message or an email.”“They also suggest setting limits on the time you spend on smart phones.”，以suggests、also suggest和also suggest引出，包括：一、关闭推送提醒；二、控制回信息时间和地点；三、限制应用智能手机时间。故选C。

5.主旨大意题。本文第一段介绍智能手机的使用情况以及优点，第二段介绍智能手机的缺点，第三段介绍两位老师的研究，最后是老师们给出的建议。本文通过对手机优点、缺点的叙述，最后提出希望大家能够合理使用手机的意见。A和B选项只是优点、缺点，过于片面，C选项文章并未提出不应该使用手机的结论，因此D选项符合主旨大意。故选D。
