1 . Screen time includes all those hours you spend in front of your computer at work, and the time you spend playing with your cell phone or watching TV.     1     According to some research, there are some convincing reasons to make the effort to look at something else other than a screen.

It's bad for your health. Being in front of a screen is almost always sedentary (久坐的) behavior, which relates to things like lower fitness levels. Turn this around by choosing something active. You do not have to do exercise at the gym.     2     They can help you keep healthy.

It messes up your sleep. When teenagers have more than four hours of screen time per day, and especially when they use their screens before going to bed, they have trouble falling asleep. If you're not sleeping well, it will not only make you feel tired the next day, but it can also affect your performance at work or in school.     3    

It hinders (妨碍) your brain’s performance.     4     Researchers aren't yet sure why this is true, but it probably has to do with the ways that technology teaches the brain to function. If kids want to perform well in situations that involve memorization or problem solving, limit their screen time.

    5     People who spend more time online, especially young people, are more likely to struggle with communication. If interpersonal communication is important to you or part of your job, you will likely get benefits if you spend less time in front of your screen.

A．It all adds up.

B．Here comes a solution.

C．If you should use a screen, try to do just that.

D．It’s not good for developing communication skills.

E．You can take a walk, or work on a project at home.

F．Kids do better in school when they have less screen time.

G．So it’s worth the effort to use your screen less and get more rest.

2 . I realized this spring that I have spent far too much time on the internet this past year, for obvious reasons, I suspect I'm not alone. And just like magic, Suzanne park's Sunny Song will never Be Famous came across my desk, a story about a 17-year old Korean American influencer who ends up in a digital detox (脱瘾) camp. My first reaction was to shrink (退缩), worried about how much of my social media self I would see in this book, and how much relative cure I would undoubtedly require as a result. But Sunny Song is such an amazing character that I was laughing out loud by page 10.

Sunny was literally born an influencer. Thanks to a video of Sunny dancing as a child, “Goggle Girl” became internet famous. She kept up the character as she grew older, obtaining almost 10,000 subscribers to her You Tube channel alone. But disaster strikes when she forgets to turn off the camera one afternoon during a live stream and a brownie ( a cake ) cooking video turns into an unprepared show with Sunny in underwear. The widely spread “Brownie Gate” will result in Sunny's being kicked out from her L A. private school-unless her parents send her to a digital detox camp, under the principal's request.

The customers in the camp are internet addicts ranging from fantasy sports and gaming players to mean girl internet celebrities. Sunny is forced to spend a month in the cornfields of Iowa on this historic family farm among these celebrities with no digital devices whatsoever, except the burner phone she brought secretly in because she's in the running for an influencer competition, and she actually has a shot!

Sunny Song Will never Be Famous was a total joy to read. I appreciate that Park does not approach social media as the enemy in this book, and for that reason I can enthusiastically recommend it to any young folks who are particularly skillful at web. Sunny reminds readers of the power of internet fare, and the consequences if that power isn't used widely.
