Research shows that isolation (隔绝) is bad for us and connected with certain diseases including depression, high blood pressure and heart disease. Yet teenagers look for isolation by using the device of our times — a screen, screens of all kinds. However, in whatever form, screens are addictive, and addictive from an early age. Research has shown that given the chance, six-month old babies prefer screens to real human faces.

Psychologist Jean Twenge, a professor at San Diego State University, believes today’s teenagers are “on the edge” of a major mental health crisis and requests, “do anything that doesn’t connect with a screen”. The number of teenagers who really see their friends very often has dropped by more than 40% since 2000. In 2015, only 56% of 17-year-old went on a date, down from 85%. Modern teenagers are slower to learn to drive, or earn money and spend more time at home. They’re “on their phone, in their room, alone and often depressed”, she says.

Some critics (评论家), however, say we should encourage our children to spend more time online. Robert Hannigan, former director of GCHQ, said in August that Britain is badly short of engineers and computer scientists, and encouraged children to develop cyber skills to compete in the digital industry.

I’m not the first to say that social media is worse than real human communication, and harms mental health. Studies show teens who spend three hours a day online are 35% more likely to suicide (自杀). The suicide rate among girls aged 12 to 14 has more than doubled in a decade.

1．Why does Jean Twenge call on teens to surf online less?

A．Social media is inclusive and keeps them connected.

B．Social media has changed every aspect of their lives.

C．Social media does great harm to their eyesight.

D．Social media is addictive and leads to mental problems.

2．What may Robert Hannigan agree that we should do?

A．Allow teens to isolate themselves from real social contact.

B．Call on teens to do anything that doesn’t involve a screen.

C．Urge children to contact people face to face instead of online.

D．Encourage children to spend more time on the Internet.

3．What is the author’s attitude towards social media?

A．Objective. B．Disapproving. C．Doubtful. D．Supportive.

4．What may be the best title for the text?

A．Teenagers looking for isolation using screens

C．Teenagers’ heavy addiction to social media

D．Different opinions on social media use

In today’s world, it can feel difficult to concentrate when your smartphone buzzes (嗡嗡响) every minute or two with reminders about updates, messages and much more. How can anyone get through a 500-page book when our brain is addicted to bite-sized content?

Gloria Mark, professor at the University of California, has spent much of her career analysing how this affects us. She has used sensors to track attention duration on screens. When the studies started, in 2004, screen attention duration was about two-and-a-half minutes, but recently, has dropped to 47 seconds.

According to Prof Mark, there were “a lot of things” that had made people more distracted. “When you switch your attention duration so rapidly, there are more errors. It takes longer to do any task and people get more stressed.” Aside from making us perform tasks less effectively, the ease with which we get distracted by one thing or another on the internet also means that we can waste time that could be spent on activities considered more worthwhile.

People who have attention disorder tend to have less grey matter in brain’s parietal cortex (顶叶皮层), highlighted Nilli Lavie, professor of psychology and brain sciences at University College London. “We see greater grey matter volume in certain regions of the brain for people with a better attentional capacity,” Prof Lavie said.

The good news is that while research has indicated that in today’s world we switch our attention more often than in the past, this change is not thought to have become hard-wired in our brains. “The solution is simple: first, decide to focus, then use strategies to remove distractions,” Prof Lavie said.

Related to this, one strategy is to set an alarm that will go off after, for example, 20 minutes. And Prof Mark advises people to look ahead to the end of the day and to consider how they might spend time then, such as relaxing on the sofa after completing their work. “I want to feel accomplished because I’ve done my work,” she said. “That can help people stay on track.”

5．What is the main problem described in paragraph 1?

A．People find it a struggle to focus. B．Bite-sized contents are addictive.

C．Long passages are outdated. D．Smartphones often disturb people.

6．What can we know about the online distractions?

A．They cause permanent changes to human brain.

B．They have similar influences on different people.

C．They increase the possibility for people to make errors.

D．They offer people convenience to deal with various affairs.

7．What does Prof. Mark advise in the last paragraph?

A．Set frequent alarms to take short breaks.

B．Create a flexible timetable to work efficiently.

C．Visualize after-work leisure time to keep daily focus.

D．Seek a relaxing environment to minimize distractions.

8．What can be a suitable title for the text?

A．Save Your Brain to Stay Relaxed B．Can We Reclaim Our Lost Focus?

C．Why Are We Losing Concentration?  D．Bite-sized Reading Ruined Our Brain
