1 . Parents express their sadness that their teenagers always have their noses in their phones. But they might need to rethink their own screen time.

A study came out from the Pew Research Center. It found that two-thirds of parents are concerned about the amount of time their teenage children spend in front of screens. But more than a third of parents expressed concern about their own screen time. Meanwhile, more than half of teens had an observation. They often or sometimes find their parents or caregivers distracted when the teens are trying to have a conversation with them. The study calls teens’ relationship with their phones at times “hyperconnected”. It notes that nearly three-fourths check messages or notifications as soon as they wake up. Parents do the same. But parents do it at a lower rate—57%. This is still substantial.

Big tech companies face a growing strong opposition. There are complaints against the addictive nature of their apps. People complain about the endless notifications and other features. They say they are created to keep people tethered(拴) to their screens.

Many teens are trying to do something about it. 52% of teens have cut back on the time they spend on their phones and 57% have done the same with social media.

Experts say parents have a big role in their kids’ screen habits and setting a good example is a big part of it. “Kids don’t always do what we say but they do as we do,” said Donald Shifrin. He is a professor of pediatrics. He teaches at the University of Washington School of Medicine. He was not involved in the Pew study. “Parents are the door that kids will walk through on their way to the world.” The study surveyed 743 U. S. teens and 1,058 U. S. parents of teens. It was conducted from March 7 to April 10.

2 . In simpler times, we never had to consider a loved one’s privacy when gift-buying. But as technology has continued its high-speed advance and growth at all costs, many companies and the products they create have long been skirting (回避) adequate data and privacy protection, leaving users at risk. For example, the audiobook reader you give to your children to send them to sleep at night now captures data on what they like.

As we continue to integrate (整合) the Internet into more of our devices and cover our homes and lives with cameras, microphones and trackers, the lack of data protection and privacy is becoming dangerous. Very few companies are being honest about how they collect, store and use data, and the only loser is the very individuals who use these products.

But that, right there, is the one chance consumers have to turn the tide (扭转局势).

The change starts with us. Buying a small device isn’t simply buying a product any more; it’s a conscious decision about whether you trust the company behind it to work in your best interests and keep you safe. It’s your responsibility as a consumer to be aware of this choice and act on it. In an ideal future, it won’t require hours of research — whether done by the buyer or by organizations — to buy safe, responsible products. But for now, it’s the best option available as these companies continue to get a free pass.

We can demand more. We must demand more. We can demand that privacy and security be taken seriously by the companies who build the products we buy. Yes, technology has vastly improved our lives, but that shouldn’t come at the cost of our safety. So if you want to give someone a gift, give them the gift of privacy. It’s the only way to make the Internet — and our lives — a little safer in this digital world.

3 . 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.
