5 . Happiness is not a warm phone, according to a new study exploring the link between young life satisfaction and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).

To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.

On average found that teens who spent more time in front of screen devices — playing computer games, using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions.

"The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising — two activities reliably linked to greater happiness."

Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness in U. S. teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.

1. Which method did Twenge's team use for the study?

A．Calculating students' happiness.

B．Asking students certain questions.

C．Analyzing data from a survey.

D．Doing experiments on screen time.

2. How does the author develop the finding of the study in paragraph 3?

A．By making a comparison.

B．By giving an example.

C．By making an argument.

D．By introducing a concept.

3. What is the purpose of the last paragraph?

A．To draw a conclusion from the study.

B．To offer some advice to the readers.

C．To prove social activities' importance.

D．To support the researchers' finding.

4. Which of the following can be the best title for the text?

A．Quitting Phones Equals Happiness

B．Screen Time Should Be Banned

C．Teens' Lives Have Changed Sharply

D．Screen-addicted Teens Are Unhappier
