Over 70 percent of American teens and adults are on Facebook with the average person spending over 90 minutes a day on all social media platforms. 【小题1】 Many of us use social media to get a sense of belonging, self-expression, or a wish to connect. Apps like Facebook and Twitter allow us to stay in touch with family members and friends and communicate with people with common interests.

But researchers have found the negative sides of social media. Facebook “addiction” is similar to drug addictions. Facebook can also make people more jealous (嫉妒的). 【小题2】 People tend to negatively compare themselves with others when they see others’ carefully designed images. A study shows that the more time young adults spent on Facebook, the worse off they felt.

【小题3】 One idea is to stay away from Facebook completely and take that “hard break.” Researchers found that after taking a one-week break from Facebook, people had higher life satisfaction and positive emotions compared to people who used Facebook regularly.

We should ask ourselves how social media makes us feel and behave, and decide whether we need to improve our social media environment. We’d better limit the number of people that we keep in close touch with. 【小题4】 It’s also a good choice to “like” only reputable (有信誉的) news, information, and entertainment sources.

We each have to make wise decisions about social media use, weighing the good and bad. As researchers put it, “online social interactions can’t completely take the place of the real thing,” and that in-person, healthy real relationships are truly important to our happiness. 【小题5】

Everywhere you go, it seems like people are using something to reduce the noise in their lives. They wear over-ear headphones on public transportation, during long flights, or in open-plan offices, or use colored earplugs (耳塞) at concerts. Silence is now big business, with the global market for noise-cancelling headphones bringing $13.1 billion in 2021. Experts predict that this figure will triple by 2031. While these market-based solutions are becoming popular, they raise a question: Are there physical and social effects to shutting out the world around us?

Noise-cancelling technology was first developed in the 1950s to reduce cockpit noise for pilots. The headphones today use technology known as active noise control. However, too much of a good thing also has its downsides. Many studies have shown that constant earplug wearing, day and night, over just one week can lead to a condition known as tinnitus (耳鸣). “When you stop listening to outside sounds, your brain starts to turn up its ‘internal volume’ so that it can still pick up on things.” McAlpine says. “If you stop the sound going into your ears, it’s like messing with how your brain is supposed to work naturally.”

When it comes to distraction (干扰), the type of noise may matter as much as volume. Moderate (适中的) background noise, around 70dB, has been found to advance performance on creative tasks, for example. “Some people can work really effectively in buzzy cafes and even airports, and yet they can’t focus in the same way in an office. Even if it isn’t as noisy,” McAlpine says. “Your brain in the office is automatically paying attention to all those other conversations — because they might be about something you need to know.”

How, then, can we deal with all the loud distractions in our modern lives? An over-dependence on noise-cancelling technology is not necessarily the solution, says McAlpine. “We have given more control to outside sources over our sound environment compared to our visual environment,” he says. If people started wearing AR/VR goggles and living in their own virtual worlds instead of focusing on improving the physical environment, “And that’s problematic.”

Forget about the “post-1995 generation”. Young people born in 1995 or later have another name in English — Generation Z. They are entering adulthood and will soon shape our future, which is why policy makers, as well as employers and marketers, are trying their best to understand these young people. So, how should we pin down the Gen Z-ers?

Most people will agree that the single biggest difference between Gen-Z and other generations is how connected they are. This is a group of people who had access to social media as soon as they were born. Social media has changed the way Gen Z-ers interact with each other and how they get and process information. They read news from Twitter, watch videos from Vine, share experiences in Instagram and post recipes in Pinterest.

“We are the first true digital natives. I can almost simultaneously create a document, edit it, post a photo on Instagram and talk on the phone, all from the user-friendly iPhone,” said Hannah Payne, an 18-year-old UCLA student.

It is noted that young people in the UK are becoming more active in Politics. Young people regard voting as one option among many to show their political engagement that can potentially influence policies. Instead of party politics, they focus more on single-topic issues such as feminism or climate change. And “much of the engagement and organizing they do takes place on social media rather than through traditional political structures,” according to the Guardians.

Gen Z-ers are also culture creators. Growing up with the Internet has freed this generation from traditional cultural expression. They are no longer willing to let their creativity be limited by their parents or traditional rules. “We decide what kind of content we want to experience and choose how we experience it,” wrote Masback, a Huffington Post blogger and a Gen Z-er herself.
