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 around the world don't necessarily agree on which food dyes are a problem, or why. That may soon change. An 2021 peer-reviewed report by California's Office of Environmental Health Hazard Assessment concluded that artificial food dyes "cause or worsen neurobehavioral problems in some children" and that the current levels 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, sala 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 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 excessively used, 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."

Falling birth rates are a major concern for some of Asia's biggest economies. Government s in the region are spending hundreds of billions of dollars trying to reverse the trend. Will it work?

Japan began introducing policies to encourage couples to have more children in the 1990s. South Korea started doing the same in the 2000s, while Singapore's first fertility（生育） policy dates back to 1987. China, which has seen its population fall for the first time in 60 years, recently joined the growing club.

While it is difficult to quantify exactly how much these policies have cost, South Korean President YoonSuk-yeol recently said his country had spent more than $200bn（£160bn） over the past 16 years on trying to boost the population. Yet last year South Korea broke its own record for the world's lowest fertility rate, with the average number of babies expected per woman falling to 0.78. In neighbouring Japan, which had record low births of fewer than 800,000 last year, Prime Minister Fumio Kishida has promised to double the budget for child-related policies from 10tn yen（$74.7bn; £59.2bn）.

Having a bigger population who can work and produce more goods and services leads to higher economic growth. And while a larger population can mean higher costs for governments, it can also result in bigger tax revenues（税收）. Also, many Asian countries are ageing rapidly. Japan leads the pack with nearly 30% of its population now over the age of 65 and some other nations in the region are not far behind. Compare that with India, which has just overtaken China as the world's most populous nation. More than a quarter of its people are between the age of 10 and 20, which gives its economy huge potential for growth. And when the share of the working age population gets smaller, the cost and burden of looking after the non-working population grow. "Negative population growth has an impact on the economy, and together with an ageing population, they won't be able to afford to support the elderly," said Xiujian Peng of Victoria University.

When Mark Anthony Gonzales saw a police officer in need of assistance, every element of the moral code installed in him through his Brazilian jiu-jitsu（巴西柔术） training morality, courage, benevolence（仁爱）—told him to stop his car and lend a hand, even though his wife, Rachel Ortiz, and his four kids were in the car.

The suspect, a balding man of medium build, was running from a police officer in San Antonio, Texas. Gonzales slowed down. So did the man being chased —to avoid running into Gonzales's minivan. That hesitation allowed the officer to catch up and take the suspect to the ground. But Gonzales quickly realized that the officer did not have control of the situation with the suspect struggling fiercely.

Gonzales put his vehicle in park and jumped out, as did Ortiz. The first thing Gonzales did was identify himself and spell out his intention to make it two-on-one in the officer's favor and not the other way around.

Then, with the man on his back and the officer struggling to control the man's upper body, Gonzales put his weight on the man's legs. Seconds later, when the suspect rolled onto his stomach, Gonzales used techniques he'd learned in the gym: digging his knee into the suspect's el bow and pulling the suspect's head toward him to maintain control from the side. He then applied an underhook a jiu-jitsu move where the hands are placed under the opponent's arm to control the shoulder and upper body—and tugged until, after a few seconds, the suspect's shoulder gave out. The officer clicked on the handcuffs and the threat was over.

Gonzales had asked his wife to record everything to protect him just in case anything was called into question. But Ortiz posted the video on Facebook, where it attracted over 56 million views.

Among those awed by the video was Brazilian jiu-jitsu instructor Rener Gracie, a fourth-degree black belt, who stated: "The combination of Gonzales's technique and his calm communication with both the officer and suspect is the stuff of legends!"

Andy's finger traced the lines on a blank United States map, each state represented by a number. He whispered to himself, "New Jersey is eating Pennsylvania, and Ohio is a chicken nugget." Beside him lay another paper with numbers 1—50 written down. Despite 20 minutes of intense concentration, all Andy had to show for his efforts were those numbers.

"OK, and Utah is the washing machine. No, Montana is the washing machine. Or North Dakota? Gah! They're all washing machines!" Andy was caught in his confusion.

This wasn't the first time his memory had failed him during a test. No matter how hard he studied, nothing seemed to stay in his brain for long. He had tried memory tricks, even spending nights examining an old paper map in his bedroom. It had given him a glimmer of hope, but now that hope felt distant.

The time was up, and Mr. Crane began collecting the answer sheets. Andy quickly stuffed his blank test into the pile, wanting to forget about it. Unfortunately, his brain seemed to remember only the things it should forget. During lunch, Andy stared at a map, frustrated that he had handed in a blank sheet of paper.

Andy's friend Aaron shrugged. "You only need a 70 to pass."

"Yeah, well it's hard to get a 70 when you hand in a blank sheet of paper," Andy mumbled, frowning.

Aaron popped a grape into his mouth. "Well, Mr. Crane will let you retake (补考) it tomorrow."

Andy was the only one standing at Mr. Crane's desk after school. He apologized quickly, head drooping. But instead of scolding him, Mr. Crane patted his shoulder, saying, "I think you are trying, but you might learn better by being active. Just practice more!"

Andy looked into Mr. Crane's eyes, finding comfort in the teacher's understanding gaze. Mr. Crane invited Andy to help him organize a pile of magnets (磁铁), each with the name of a state on it. On the wall hung a large magnetic map — part of a review game the class had been playing.

注意：1. 续写词数应为150左右；2. 请按如下格式在相应位置作答。

As Andy arranged the magnets, an idea suddenly came into his mind.

……

When doing homework, Andy was told he scored an 88 on the retake.

My Favorite Spring Festival Eve Dish

Long Chenchen, the mascot for China's upcoming Dragon Spring Festival Gala, (release) recently, with a lot of design details showing the aesthetics of Chinese cultural elements.

(celebrate) the year 2024, "Long Chenchen" has been designed as a cute yet lively dragon, colored orange and red and with a pair of doll eyes. The (seem) cute-looking dragon takes inspiration from Chinese archaeological discoveries. The design of its nose was inspired by a dragon-shaped jade item that was discovered in the Erlitou Ruins, major site in Luoyang, Central China's Henan province that witnessed the rise and fall of the Xia and Shang dynasties. The fire shape pattern on its shoulder was inspired by a bronze piece with cloud patterns dating back to the Spring and Autumn Period, multiple materials appeared and social changes were underway.

receiving many likes, the mascot has also sparked criticism. Some netizen doubt the dragon character might have been synthesized (合成) by artificial intelligence. (admit) that it has some "imperfections", CMG, a design studio said it was created by designers "one stroke after another" and that "all the details about the dragon, including its patterns, colors and face, have been revised by designers through a lot of versions."

Along with such verbal (explain), a short video showing the design team working on the mascot has been posted on Sina Weibo by CMG. The media group's response to the character's design has become a (trend) topic on Sina Weibo and has been viewed by more than 200 million netizen. " it was created by AI or human beings, I think the mascot has successfully delivered the spirit of the dragon." one netizen posted on Sina Weibo.

One day, I was standing on the boat when a very large female leopard seal swam by. I put on my diving gear and got my camera. I was 1 . My mouth was dry. At first, I couldn't even move. But I knew it was time to2 this mysterious creature.

I jumped into the freezing water. Immediately, the seal swam toward me. Then she put my entire camera—and much of my3 — into her mouth. Although the seal was putting me at risk, I tried not to4 any fear. After a few seconds, she let go of my head. She5 me a few more times and swam away. Then she6 with a live penguin. She even tried to show me how to7 it. She tried to push the penguin into my camera — she thought the camera was my8 ! The seal thought I was just another large animal, and she was trying to9 me, I realized.

By now, she didn't seem very10 . She stayed by me for four days. One time, she noticed another leopard seal11 behind me. She made a deep, threatening sound and12 the other seal away.

Those four days were the most incredible experience I ever had as a wildlife13 . I got some amazing pictures. I also learned that animals do not always behave the way we14 . My relationship with this powerful and15 animal will stay with me forever.

Benefits of Personality Tests

Can identifying one's personality type using the MBTI and other personality assessments really help? They may.

Better understand others

After taking a personality test and seeing our results, we can gain a better understanding of all the different perceptions and reactions that others might have to the same situation. . No personality type is "better" than any other — just different. Each perspective brings something new and interesting to the table.

Identify our likes and dislikes

Maybe we've always hated talking on the phone but never really understood why. . By using personality tests like the MBTI, we can learn more about where we lie on the extroversion/introversion and thinking/feeling continuum (连续性). This helps us better understand why we prefer certain things and dislike others.

.

Learning more about our personality type can also help us discover new ways to approach challenges. Knowing what might work best for our personality type can give us new ideas on how to solve problems, deal with stress, cope with conflict, and manage our work habits.

Recognize our strengths and weaknesses

Knowing what we are good at can be important in a wide variety of situations, whether we are picking a college major or thinking about running for a seat on our local school board. For example, if we know that we are an ISTJ (introverted, sensing, thinking, and judging) on the MBTI, we might recognize that certain aspects of our personality might qualify as strengths in some situations and weaknesses in others. , it can sometimes trip us up in situations where we need to let other people take control.

A. Know which situations are ideal for us

B. Hold on to ideas about who we are

C. While they reveal truth that showcases different aspects of personality

D. Here's an overview of the many benefits of personality tests

E. This is important because we all have different ways of seeing and interacting with the world

F. While our organizational skills and carefulness can be a major strength in our work

G. Or perhaps we've always needed much time to think about a problem before making a decision

One of the biggest challenges that traditional educators face is how to unlock students' love of learning. Once students overcome their fear or unwillingness, they will be on the track of becoming motivated learners.

In order to help students discover the joy in learning, some teachers are turning to a simple but effective strategy called gamification-using game-related elements such as activities and rewards to promote students' engagement in class. With an origin in educational psychology, this approach is designed to reach students by making the learning process funny and interesting.

What's more, researches show that gamification can also make assignments less stressful. Without too much pressure, students will associate learning with curiosity and joy. Accordingly, they feel like continuing the journey because positive feelings have boosted their confidence.

But like any other strategies, gamification has its drawbacks when used incorrectly. It is very likely that some students only focus on winning rewards but have no interest in understanding concepts or learning new skills--exactly the opposite of the desired outcome. To avoid this, teachers can help prevent students from becoming wrongly motivated by choosing suitable rewards. Instead of class parties or snacks, try rewards that help students develop a passion for academic subjects. 

For example, have students earn points towards a class field trip by behaving and doing their assignments, or pair subjects that a student dislikes with fun books or activities to encourage motivation. That way, they associate fun with reading, math, or other skills. More examples include competing on a leader-board, holding a talent show, or playing other team-building games. All activities and rewards need to be carefully selected and well arranged. 

If you're having a hard time getting your class interested in learning, talk with them together or individually about what motivates them and include it into your student engagement strategies.
