Scientists say we are all born with a knack for mathematics. Every time we scan the cafeteria for a table that will fit all of our friends, we're exercising the ancient estimation center in our brain.

    Stanislas Dehaene was the first researcher to show that this part of the brain exists. In 1989, he met Mr. N who had suffered a serious brain injury. Mr. N couldn't recognize the number 5, or add 2 and 2. But he still knew that there are “about 50 minutes” in an hour. Dehaene drew an important conclusion from his case: there must be two separate mathematical areas in our brains. One area is responsible for the math we learn in school, and the other judges approximate amounts.

    So what does the brain's estimation center do for us? Harvard University researcher Elizabeth Spelke has spent a lot of time posing math problems to preschoolers. When he asks 5-year-olds to solve a problem like 21+30, they can't do it. But he has also asked them questions such as, “Sarah has 21 candles and gets 30 more. John has 34 candles. Who has more candles?” It turns out preschoolers are great at solving questions like that. Before they've learned how to do math with numerals and symbols, their brains' approximation centers are already hard at work.

    After we learn symbolic math, do we still have any use for our inborn math sense? Justin Halberda at Johns Hopkins University gave us an answer in his study. He challenged a group of 14-year-olds with an approximation test: The kids stared at a computer screen and saw groups of yellow and blue dots flash by, too quickly to count. Then they had to say whether there had been more blue dots or yellow dots. The researchers found that most were able to answer correctly when there were 25 yellow dots and 10 blue ones. When the groups were closer in size, 11 yellow dots and 10 blue ones, fewer kids answered correctly.

    The big surprise in this study came when the researcher compared the kids' approximation test scores to their scores on standardized math tests. He found that kids who did better on the flashing dot test had better standardized test scores, and vice versa (反之亦然). It seems that, far from being irrelevant, your math sense might predict your ability at formal math.

    In Europe, there is no escape for those who do not appreciate art and architecture(建筑). It is a heaven for people who want to feel like they have been transported to famous historical time periods from America. For me, Europe was a complete contrast from America. London and France had a more royal feel than New York, and Rome felt more ancient. I wasn't just on a different continent; it felt like I was in a different century.

    My parents and I visited London, Paris and Rome this summer in celebration of the end of my high school experience. It was supposed to be a break from a life as busy as a bee in New York, the constant stress, the crowded subway rides, and the weary body that had accompanied me for the last four years. It was an opportunity to appreciate Europe the way I couldn't do it just by reading history books.

    My favorite parts of London were the Tower of London and the Churchill War Rooms. As a site of past executions(刑场), the Tower of London displayed punishing devices from the 16^th and 17^th century and told stories of various members of the royal family who had ever been imprisoned in the tower, some even imprisoned by their own family members when they were seen as a threat to the crown. Besides that, I also got to see the royal family's crown jewels, amazingly beautiful.

    The Churchchill War Rooms, though very different from the Tower of London, were also spellbinding from a historic perspective. I am not a history fan, but I enjoy museums, and I took fancy in the Churchchill Museum inside the War Rooms that detailed the events of Churchchill's life and World War II. Everything I saw in it built up his life from his childhood to his last years, creating a three-dimensional Churchchill in my mind who was a person just like myself. He longed for more, he made mistakes, he experienced loneliness and sadness. But he had also done some remarkable things like uniting Britain during World War II.

    Our rewarding trip ended in Rome a couple of days later.

    Skiing has always been a big part of Kamikaze shiffrin's life. Her dad ski raced all through college and her mom raced and coached skiing. The Siffrins taught Mikaela and her brother, Taylor. To ski at a very young age. At two and a half years old, Mikaela made her first ski run down her driveway on plastic skis.

    Mikaela loved skiing. From ages 8 to11, she did hundreds of training runs on small hills to learn the skills of slalom skiing (障碍滑雪). When Mikaela was 11, she began to learn at the Burke Mountain Academy, a Vermont boarding school for skiers. She took classes, studied, and practiced her skiing. According to Burke Mountain Academy headmaster Kirk Dwyer, "What separated Mikaela from others was the degree of her commitment (投入) to be the best. Mikacla practiced more than anyone and believed in herself then and now." At age 14, Mikaela began her international career when she raced in the world championship for13 and 14 -year-olds. And she won!

    By the time she was17, she had already won her first World Cup race. "Living away from home four and five months at a time can be difficult" Mikaela says. "But it can also be exciting. I'm getting to see the world." When Mikaela began ski racing in Europe, her mother, Eileen, stayed with her. She worked as her high school teacher while they were on the road. "She has always been a super-hard worker," says Eileen.

    For Mikaela, working hard is a full-time job. Even her off-season is work time. "If you want something, just try your best," she says. At the 2014 Winter Olympic Games in Sochi, Russia, 18-year-old Mikaela Siffrin became the youngest slalom skier ever to win an Olympic gold medal.

    I traveled to London, England in the spring of 2016. Actually, I traveled with CAPA International Education on a study program. At that time, I did a full three­month program but I traveled on weekends and during breaks.

    I used to live in a small town outside New York. The idea of big cities has always excited me and I wanted to take advantage of that once­in­a­lifetime opportunity. It was a great opportunity for me to see how independent I could be in another country, because I hope to travel a lot more in the future.

    I lived in a flat in Ealing Broadway with several other students from different American schools. The biggest surprise I found there was the culture shock I experienced. I had expected traveling to London to be an easy transition (转变) for me because I thought their culture was close to that of America. But you know the language and the people were greatly different from what I had expected. They had different accents. In fact, they were noisy and more free­thinking than most Americans I knew.

    However, I tried to take part in their giant Chinese New Year celebration in Trafalgar Square. I went to several Jewish society holiday celebrations and actively participated in any cultural activities I knew at that time. It was great to be able to truly put myself in their culture. These are experiences I couldn't get anywhere else.

    I would suggest people hoping to follow in my footsteps not let anything hold them back from exploring the foreign cultures presented to them. Yes, you are there for school, but your number one priority (优先) is yourself. So make sure you go home with no regrets. Do not miss anything!

Do you know that junk food isn't healthy? Of course you do! Do you eat it anyway? Of course you do! But a new study shows teaching adolescents about the ways food companies fool them into thinking junk food is cool can encourage kids to fight back—by eating healthier.

The pull of junk food can be super-strong. It's designed to be tasty, which makes eating well one of the great health challenges of our time. Everyone from doctors to the government has been trying to handle it. Yet we keep eating junk food.

Professor Christopher Bryan says, "Food companies want you to want junk food." They spend millions of dollars coming up with new ways to promote junk food consumption. They hire scientists to make new junk food almost irresistible. They might do this, for example, by adding more sugar. Rats fed junk food for six weeks will even walk across a floor that gives them electric shocks just to get more of such food.

Food ads often make unhealthy junk food seem healthy by featuring professional athletes, fit-looking pop stars and smiling, active teens. "We thought when the students learned this, it would matter to them," Bryan says. He worked with 8th graders at a Texas school. Half of them got a lesson Bryan created. It focused on the ways junk food is advertised, or marketed. A second group received lessons that focused on health. These lessons informed students junk food is bad, and that foods like apples or carrots are a better choice. The students learned a bad diet can lead to major weight gain, and that being overweight puts people at risk for serious diseases. They also learned how eating well now can keep you healthy when you're older.

After the lessons, the kids in both groups were asked how they felt about junk food. Most didn't have positive feelings about these unhealthy foods.
