1 . Twelve-year-old Catherine has a lot of friends—632, actually, if you count up her online friends. And she spends a lot of time with them.

But is it possible that Catherine’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.

Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not words with friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.

Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platform.

In fact, in many ways, online communication can make friendships stronger. “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.

Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual world, we will have little time for our real-world friendships,” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need anyone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

2 . Are you happy with your appearance?     1    

“Almost all the girls with single-fold eyelids (单眼皮) in our class have had double eyelid operations,” Zeng, a Senior 2 student from Chengdu, told Xinhua. Zeng had the same surgery done this summer.     2    

From popular photo-editing apps to plastic surgery (整形手术), it seems that large eyes, pale skin and a skinny body are the only standard for beauty these days. But can following this standard really make us feel good about ourselves?

    3     . According to Huxiu News, over six in ten girls choose not to take part in certain daily activities, such as attending school, because they feel bad about their looks. As much as 31 percent of teenagers avoid speaking up in class because they worry that others will notice their looks.

“Many teenagers are upset about their appearance because they believe in unrealistic standards of beauty,” experts say.       4     Seeing all these things can make anyone believe that they’re too dark, too fat, too short, or too tall.

However, trying to live up to strict standards can make us feel anxious. What troubles us is not just our “imperfect” looks, but the fact that we criticize ourselves too much.

    5     Plus-size models are being featured in some fashion shows. All of us should be just as confident as they are.

4 . A shocking 53.6 million metric tons of electronic waste was discarded last year, a new UN-backed report has revealed. The report shows that e-waste is up by 21% from five years ago. This isn’t surprising, considering how many more people are adopting new technology and updating devices regularly to have the latest versions, but the report also shows that national collection and recycling strategies are nowhere close to matching consumption rates.

E-waste contains materials including copper (铜), iron, gold and silver, which the report gives a conservative value of $ 57 billion. But most are thrown away or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $ 14 billion, but only $ 4 billion-worth is recovered at the moment.

While the number of countries with national e-waste policies has grown from 61 to 78 since 2014, there is little encouragement to obey and a mere 17% of collected items are recycled. If recycling does occur, it’s often under dangerous conditions, such as burning circuit boards to recover copper, which “releases highly poisonous metals” and harms the health of workers.

The report found that Asia has the highest amounts of waste overall, producing 24.9 million metric tons (MMT), followed by Europe at 12 MMT, Africa at 2.9 MMT, and Oceania at 0.7 MMT.

But whose responsibility is it? Are governments in charge of setting up collection and recycling points, or should companies be responsible for recycling the goods they produce? It goes both ways. Companies do need to be held accountable by government regulations and have incentives to design products that are easily repaired. At the same time, governments need to make it easy for citizens to access collection points and deal with their broken electronics in a convenient way. Otherwise, they may turn to the easiest option — the landfill.

5 . Sometime in the early 1960s, a significant thing happened in Sydney, Australia. The city discovered its harbor. Then, one after another, Sydney discovered lots of things that were just sort of there — broad parks, superb beaches, and a culturally diverse population. But it is the harbor that makes the city.

Andrew Reynolds, a cheerful fellow in his early 30s, pilots Sydney ferryboats for a living. I spent the whole morning shuttling back and forth across the harbor. After our third run Andrew shut down the engine, and we went our separate ways — he for a lunch break, I to explore the city.

“I’ll miss these old boats,” he said as we parted.       

“How do you mean?” I asked.

“Oh, they’re replacing them with catamarans. Catamarans are faster, but they’re not so elegant, and they’re not fun to pilot. But that’s progress, I guess.”

Everywhere in Sydney these days, change and progress are the watchwords (口号), and traditions are increasingly rare. Shirley Fitzgerald, the city’s official historian, told me that in its rush to modernity in the 1970s, Sydney swept aside much of its past, including many of its finest buildings. “Sydney is confused about itself,” she said. “We can’t seem to make up our minds whether we want a modern city or a traditional one. It’s a conflict that we aren’t getting any better at resolving.”

On the other hand, being young and old at the same time has its attractions. I considered this when I met a thoughtful young businessman named Anthony. “Many people say that we lack culture in this country,” he told me. “What people forget is that the Italians, when they came to Australia, brought 2000 years of their culture, the Greeks some 3000 years, and the Chinese more still. We’ve got a foundation built on ancient cultures but with a drive and dynamism of a young country. It’s a pretty hard combination to beat.”

He is right, but I can’t help wishing they would keep those old ferries.

8 . In the last 50 years the media influence has grown increasingly with the advance of technology. First there was the telegraph, then the radio, the newspaper, magazines, the television and now the Internet.

We live in a society that depends on information and communication to keep moving in the right direction and do our daily activities like work, entertainment, health care, education, personal relationships, traveling and anything else that we have to do.

In our daily life, we rely on the media to get the current news and facts about what is important and what we should be aware of. We have put our trust on the media as an authority to give us news, entertainment and education. However, the influence of mass media on our kids, teenagers and society is so big that we should know how it really works.

Of all the media distribution channels the most influential has been the television. We are constantly exposed to thousands of images of violence, advertising, sex, celebrities and much more, in fact a child may be exposed to about 40,000 ads a year.

But who owns the media, which are the companies or people that shape our values, beliefs and decisions? In America, the media is basically dominated by five major companies. Those five companies own 95% of all the media that we get every day. They own the major entertainment theme parks, entertainment movie studios, television and radio broadcast networks and programming, video news and sports entertainment. They also own integrated telecommunications, wireless phones, video games softwares, electronic media, the music industry and more.

Years ago there was more diversity in companies, but they have been combined so now they are just a few and they have the power to shape our opinions and beliefs and those of our kids. So it’s important to be aware of what your kids are exposed to every day and you should also try to look at things from different perspectives and not just from the one the media gives you.

9 . Feeling controlled by your to-do list can certainly make you unhappy, but new research suggests that more free time might not be the magic elixir (灵丹妙药) many of us dream it could be.

In a new study shown last week, researchers analyzed data from two major surveys about how Americans spend their time. Together, the surveys included more than 35,000 respondents (受访者). The researchers found that people with more free time generally had higher levels of subjective well-being—but only up to a point.

People who had up to two hours of free time a day generally reported they felt better than those who’d had less time. But people who had five or more hours of free time a day generally said they felt worse.

So finally the free-time “sweet spot” might be two to three hours per day, the findings suggest. “While too little time is bad, having more time is not always better,” said Marissa Sharif, lead author of the paper.

Of course, most people know that being too busy can cause stress. But the new study is not the first to question whether more free time will actually make people as happy as they believe it will. Part of “sweet spot” has to do with how people spend the free time. Researchers conducted several smaller online experiments. In one they asked participants to imagine having 3.5 to 7 free hours per day. They were asked to imagine spending that time doing “productive” things (like exercising) or to imagine doing “unproductive” activities (like watching TV).

Study participants believed their well-being would suffer if they had a lot of free time during the day—but only if they used it unproductively. Though that experiment was hypothetical (假设的), which is one limitation of the new research, it’s certainly in line with other research showing that being in a state of “flow” can be good for people’s mental health.

In other words, how people use their free time matters, Sharif said. Of course, what feels “productive” is up to you.
