1 . While teenagers who are at risk of depression with risky behaviors — drinking alcohol, smoking cigarettes and cutting classes often alert parents and teachers that serious problems are brewing, a new study finds that there’s another group of adolescents who are in nearly as much danger of experiencing the same mental symptoms.
These teens use tons of media, get insufficient sleep and have a sedentary (不爱活动的) lifestyle. Of course, that may sound like a description of every teenager on the planet. But the study warns that it is teenagers who engage in all three of these practices in the extreme that are truly in a dangerous position. Because their behaviors are not usually seen as a red flag, these young people have been called the “invisible risk” group by the study’s authors.
The study’s authors surveyed 15,395 students and analyzed nine risk behaviors, including excessive alcohol use, illegal drug use, heavy smoking and high media use. Their aim was to determine the relationship between these risk behaviors and mental health issues in teenagers. The group that scored high on all nine of the risk behaviors was most likely to show symptoms of depression; in all, nearly 15% of this group reported being depressed, compared with just 4% of the low-risk group. But the invisible group wasn’t far behind the high-risk set, with more than 13% of them exhibiting depression.
The findings caught Carli off guard. “We didn’t expect that,” he says. “The high-risk group and low-risk group are obvious, but this third group was not only unexpected. It was so distinct and so large—nearly one third of our sample—that it became a key finding of the study.”
Carli says that one of the most significant things about his study is that it provides new early warning signs for parents, teachers and mental health-care providers. And early identification, support and treatment for mental health issues, he says, are the best ways to keep them from turning into full-blown disorders.

4 . That artificial food dyes (染料) are unhealthy is not news. Some are known to cause hyperactivity (多动症) in some children, affecting their ability to learn. But regulatory agencies (监管机构) around the world don’t necessarily agree on which food dyes are a problem, or why. That may soon change. A 2021 peer-reviewed report by California’s Office of Environmental Health Hazard Assessment concluded that artificial food dyes “cause or worsen neurobehavioral (神经行为的) problems in some children” and that the current levels that are regarded safe for consumption by the federal government are too high.
California is now considering requiring warning labels on food products and dietary supplements containing the seven most commonly used artificial dyes. The warning label requirement would put California on par with the European Union, which since 2010 has required food products containing certain artificial food dyes to carry warning labels about their negative effect on activity and attention in children.
Artificial dyes are used in foods for one reason: to make products look prettier. Bright colors make candies appealing, especially to kids. But dyes are also in chocolate cake mixes, salad dressings and other products that don’t seem to cry out for a color boost.
In Europe, it was the 2010 label lawmaking that triggered (引发) companies’ decisions to reformulate. “If you’re a company, you do not want to put a warning label on your product.” says Lefferts, an environmental health consultant. Warning labels are why European Starburst Fruit Chews are now colored with natural products, not the artificial dyes that brighten their North American counterparts (同类商品).
Given that artificial food dyes are used far more than needed, we need to be more cautious. After all, we don’t dye fresh fruits and vegetables, but we do dye candy and sprinkles, points out Joe Schwarcz, a chemistry professor at McGill University in Montreal. “The foods in which you find food dyes are foods that are poor in nutrition,” he says. “If you limit foods that contain food dyes, you automatically make your diet better.”

7 . 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.

9 . The Stanford marshmallow (棉花糖) test was originally conducted by psychologist Walter Mischel in the late 1960s. Children aged four to six at a nursery school were placed in a room. A single sugary treat, selected by the child, was placed on a table. Each child was told if they waited for 15 minutes before eating the treat, they would be given a second treat. Then they were left alone in the room. Follow-up studies with the children later in life showed a connection between an ability to wait long enough to obtain a second treat and various forms of success.
As adults we face a version of the marshmallow test every day. We’re not tempted by sugary treats, but by our computers, phones, and tablets — all the devices that connect us to the global delivery system for various types of information that do to us what marshmallows do to preschoolers.
We are tempted by sugary treats because our ancestors lived in a calorie-poor world, and our brains developed a response mechanism to these treats that reflected their value — a feeling of reward and satisfaction. But as we’ve reshaped the world around us, dramatically reducing the cost and effort involved in obtaining calories, we still have the same brains we had thousands of years ago, and this mismatch is at the heart of why so many of us struggle to resist tempting foods that we know we shouldn’t eat.
A similar process is at work in our response to information. Our formative environment as a species was information-poor, so our brains developed a mechanism that prized new information. But global connectivity has greatly changed our information environment. We are now ceaselessly bombarded (轰炸) with new information. Therefore, just as we need to be more thoughtful about our caloric consumption, we also need to be more thoughtful about our information consumption, resisting the temptation of the mental “junk food” in order to manage our time most effectively.
1. What did the children need to do to get a second treat in Mischel’s test?A.Take an examination alone. | B.Share their treats with others. |
C.Delay eating for fifteen minutes. | D.Show respect for the researchers. |
A.the calorie-poor world and our good appetites | B.the shortage of sugar and our nutritional needs |
C.the tempting foods and our efforts to keep fit | D.the rich food supply and our unchanged brains |
A.Be selective information consumers. | B.Absorb new information readily. |
C.Use diverse information sources. | D.Protect the information environment. |
