1 . Before uploading a photo of ourselves to social media, the chances are that we’ll use an app to smooth our skin, enlarge our eyes, and sharpen our jawlines. With a couple of ta ps on our mobile phones, we can get a quick fix and present the “best” version of ourselves to the world. However, the problem is that when we simply edit out our imperfections, we’re also changing the way we look at ourselves.

Last month, researchers published the article Selfies — Living in the Era of Filtered Photographs. The article analyzed photo editing apps’ bad influences on people’s self-respect and their possibility of causing anxiety about appearance. The researchers also warned that such apps might make the young generation misjudge themselves. “These apps allow one to change his or her appearance in minutes and follow an unrealistic standard of beauty,” the article read.

In the past, people may have compared their looks to those of famous persons. But for today’s young people, beauty standards are most likely set by what they see on social media. “From birth, they are born into an age of social platforms where their feelings of self-worth can be based purely on the number of likes and followers that they have, which is linked to how good they look,” British cosmetic doctor Tiji on Esho told The Independent. This is why many young people suffer an identity trouble when it comes to appearance.

“Now you’ve got this daily comparison of your real self to the fake self that you present on social media,” Renee Engeln, professor of psychology, told the HuffPost website. Engeln further pointed out that when people spend too much time making such comparisons, they might become “beauty sick” and find it difficult to accept what they actually look like. “Because between you and the world is a mirror, and it’s a mirror that travels with you everywhere. You can’t seem to put it down,” she told The Washington Post. So when we look at ourselves in a real mirror, we shouldn’t think, “Do I look as good as myself in the filtered photos?” Instead, we should think, “I feel good; I have my health.”

6 . It was a comfortable sunny Sunday. I was going to meet an old university friend I hadn’t seen for years, and was really excited.

My train was running a little late, but that was no big problem—I could text him to say I would be delayed. He would understand. But … where was my mobile phone? I had that familiar sinking feeling. Yes, I’d left it at home.

No mobile phone. I’m sure I’m not alone in feeling anxious, on edge and worried when I don’t have my phone with me. In fact, I know I’m not alone: two－thirds of us experience “nomophobia (无手机恐惧症)”， the fear of being out of mobile phone contact.

That’s according to a study from 2012 which surveyed 1，000 people in the UK about their relationship with mobile phones.

It says we check our mobile phones 34 times a day, and that 18—24－year－olds, especially girls, are the most likely to suffer fear of being without their mobiles: 77% of them say they are unable to be apart from their phones for more than a few minutes.

Do you have nomophobia?

● You never turn your phone off.

● You frequently check for texts, missed calls and emails.

● You always take your phone to the bathroom with you.

● You never let the battery run out.

It’s funny to think that around 20 years ago the only people with mobile phones would be businessmen carrying their large, plastic “bricks”. Of course, these days, mobile phones are everywhere. A UN study from this year said there would be more mobile phones than people across the world by the end of 2020.

And when there are more phones than people in the world, maybe it’s time to ask who really is in charge? Are you in control of your phone, or does your phone control you?

So, what happened with my university friend? When I arrived a few minutes late he just laughed and said: “You haven’t changed at all—still always late!” And we had a great afternoon catching up, full of jokes and stories, with no desire to check my phone.

Not having it with me felt strangely free. Maybe I’ll leave it at home on purpose next time.

7 . In the days before the Internet, critical thinking was the most important skill of informed citizens. But in the digital age, according to Anastasia Kozyreva, a psychologist at the Max Planck Institute of Human Development, and her colleagues, an even more important skill is critical ignoring.

As the researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with a lot of emotional and eye-catching stories while providing little useful information, so they can expose us to profit-generating advertisements. Therefore,we are no longer customers but products, and each link we click is a sale of our time and attention. Toprotect ourselves from this, Kozyreva advocates for learning the skill of critical ignoring, in which readers intentionally control their information environment to reduce exposure to false and low-quality information.

According to Kozyreva, critical ignoring comprises three strategies. The first is to design ourenvironments, which involves the removal of low-quality yet hard-to-resist information from around. Successful dieters need to keep unhealthy food out of their homes. Likewise, we need to set up a digital environment where attention-grabbing items are kept out of sight. As with dieting, if one tries to bank onwillpower not to click eye-catching “news”, he’ll surely fail. So, it’s better to just keep them out of sightto begin with.

The next is to evaluate the reliability of information, whose purpose is to protect you from false and misleading information. It can be realized by checking the source in the mainstream news agencies which have their reputations for being trustworthy.

The last goes by the phrase “do not feed the trolls.” Trolls are actors who internationally spread false and hurtful information online to cause harm. It may be appealing to respond to them to set the facts straight, but trolls just care about annoying others rather than facts. So, it’s best not to reward their bad behaviour with our attention.

By sharpening our critical ignoring skills in these ways, we can make the most of the Internet while avoiding falling victim to those who try to control our attention, time, and minds.

9 . Every festival has its own meaning. Labor Day, for example, celebrates the value of hard work. Thanksgiving is about showing thanks to people around you. And Valentines’ Day is a time when you express love to your loved ones. But somehow it now seems that all festivals we just care about one thing — shopping. And that can be a big problem.

“In a way, over-consumption (过度消费) is the mother of all our environmental problems,” Kalle Lasn once told CNN. Lasn is the organizer of Buy Nothing Day, a day set up in Canada in 1992 to fight against unhealthy spending habits, and has now become an international event. It’s held on the day, which is known as Black Friday — a famous shopping day in the US and Canada.

You can see the irony (讽刺) here.

Even though the idea of Buy Nothing Day was brought up 26 years ago, we seem to need it now more than ever. It’s just as Lasn said, all the different kinds of pollution in our lives today — bad air quality, the reduction of forest area, endangered animal species, and plastic bags found in the ocean — seem to be the same cause: over-consumption.

The latest example is the Singles’ Day shopping craze of Nov 11, which saw a new sales record. But as Nie Li, a campaigner at Greenpeace, told Reuters, “Record-setting over-consumption means record-setting waste.” And it was reported that last year the Singles’ Day packages left more than 160,000 tons of waste, including plastic and cardboard. The Collins Dictionary has also just named “single-use” its Word of the Year, pointing out the problem that there’re too many things we tow out after only using them once.

So, Buy Nothing Day might only be here for one day a year, but it’s not just to remind us to the a break from shopping on that day, but to change our lifestyle completely, focusing on fun “with people we care about” rather than wasting money on useless things.

10 . While English is getting more important in our schools, Chinese has become popular among foreign kids. But Chinese can be more difficult to learn. At least 16-year-old Piao Chenglong thinks so. “English is easier for me. Chinese characters (汉字) have too many strokes (笔画),” said Piao. “But I want to learn it. I want to study at Beijing University when I grow up.” Piao is from Korea. He came to China in 2008.

In Korea, there are more than 300, 000 Chinese learners like Piao. Some Korean students begin to learn to write the language on their first day at school. To help students learn Chinese, Korea holds speaking competitions for high school students every year.

Chinese isn’t just popular in Korea. People from all the world want to learn it. The Ministry of Education of China says that nearly 130 million people from 85 countries are learning Chinese. This number will be increasing to 800 million in the coming years.

In America, Chinese is the second most popular foreign language after Spanish. Some American middle schools have Chinese classes. Students learn to make jiaozi and tie Chinese knots (中国结). Some even try to write and draw in the Chinese way!

People want to learn Chinese because China is becoming such an important country. Foreign countries want to understand China better to help them with business. The Chinese government is also helping the world learn Chinese. It has sent more than 200 Chinese teachers to more than 60 countries in the world. Many more Confucius Institutes (孔子学院) will be set up in the world. These institutes will teach Chinese to foreign students.
