Chinese students always complain that they're under great pressure and don't get enough sleep. But they may be surprised to learn that they're much luckier than their peers (同龄人) in South Korea and Japan, according to a recently published report, conducted by Shanghai Academy of Social Sciences on the physical and mental health of senior high school students in the three Asian countries.

    According to the study among nearly 6,000 high school students in the three countries, Chinese students are the tallest but poorest in physical fitness. Chinese students are on average 168.17cm, compared with 167.61cm for South Korean students and 164.70cm for Japanese students. Chinese students asked for sick leave more than students in other countries. About 72 percent of Korean students never asked for sick and injury leave during high school, compared to 53 percent for Japanese students and 45 percent for Chinese students. Moreover, Chinese students drink alcohol and smoke earlier than Korean and Japanese students. Around 70 percent of Chinese students have drunk alcohol, compared to 50 percent for Korean and Japanese students.

    According to the survey, Japanese and South Korean students suffer more pressure than their Chinese peers. Statistics (统计) show 16 percent of students in China said they experienced mental pressure often over the past year, while the numbers in Japan and South Korea were 33 percent and 47 percent respectively. Their worries come from “study”, “future after graduation”, “friendships” and “relationship with their parents”. To go with stress, 57.9 percent of Korean students sleep the least, less than six hours a day, compared with 46.6 percent of Japanese students and 30 percent of Chinese students.

    More Chinese students were satisfied with their physical appearance, double that of students in the survey from Japan and South Korea. The report said that over half of students in South Korea had tried to lose weight in the past year, while in China the figure was only 22 percent.

    In measures of self-worth, such as “I think I am valuable” and “I think I am successful”, “I can complete many things”, “I won't give up to failure,” Chinese students showed greater self-confidence than students in Japan and South Korea.

    The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator (发电机). The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity — roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meal tickets worth $ 36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel.

    The plan, a world-first, will start on 19 April and run for a year. Only guests staying at the hotel will be able to take part. Frederikke Toemmergaard，hotel spokeswoman, said, “Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don't think people will take advantage of our programme.”

    Copenhagen has a long-standing cycling tradition and 36 % of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen. dk. US environmental website treehugger. com recently voted Copenhagen the world's best city for cyclists. “Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as a symbol of the hotel's green profile (形象).”

    If successful，the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement.

    Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter?

    More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language.

    You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer.

    Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and the State University of Campinas are both highly ranked internationally. Your money will go a long way there, too.

    Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.

    The World Health Organization recently said that it planned to add gaming disorder (游戏成瘾) to its new list of disease classifications, angering the gaming industry but pleasing doctors who hope it may make treatment more easily available.

    Some US experts said it would make little difference when it comes to helping people with the disorder, although others said it would bring attention to a disorder that people sometimes don't recognize. So some experts disagree WHO's plan.

    Many of us enjoy video games, but does playing our favorite game for a couple of hours every night mean we're suffering from gaming disorder? Not according to the WHO.

    The symptoms listed by the WHO include a lack of control over gaming, treating gaming more seriously than other life interests and daily activities, and continuing to play games despite the negative consequences that playing them might have.

    "The behavior pattern is enough to result in significant damage to one's personal, family, or social life." the WHO said.

    Meanwhile, Douglas Gentile of Iowa State University has carried out influential research into the cause of gaming addiction in young people." I and many others had assumed that gaming is not really a problem but is a symptom of other problems," he told NBC News. Many had thought it was simply a failure of self-control. To see if it was, Gentile's team studied a group of children who had been gaming for several years." We found that when kids became addicted, their anxiety increased … and their grades decreased," Gentile said. When kids were able to back off from gaming, their symptoms disappeared, he added.

    Gentile thinks medical organizations should pay attention to the WHO's proposal." This isn't an issue of opinion; it's an issue of science," he said." This is a major scientific and medical organization. They don't do things lightly and without reason."

    Dr Petros Levounis, chair of psychiatry at the New Jersey Medical School at Rutgers University, said that he hoped the WHO's proposal would lead to more research into obsessive (过度的) behavior among all types of people.

    "Now, there is renewed interest and excitement," he said. So some experts are in favour of WHO's plan.

    We live in a world where new technologies and new methods are constantly being introduced. As humans, we are learning machines. We are most alive and functioning closest to our potential when we are learning, adapting, adjusting and finding new ways, approaches and techniques to improve our lives or the lives of others in some way.

    Learning does not finish when we leave school. Learning can become a way of life that helps us to achieve our greatest potential. We shall never stop learning, as there is always something new and interesting to discover.

    Lifelong learners never fail, because failure isn't in the vocabulary. Failure is just defined as "a failure to learn".

    When a project does not go according to the plan, lifelong learners ask themselves "What can I learn from this？" and follow up with" How can I do this differently and achieve my outcome？"They do not say, "I did not get to my goal, so I must be a failure."

    There is a wonderful saying: "The only way to fail is to quit！" Robert Kiyosaki, author of Rich Dad, Poor Dad, said, "The only reason I am standing up here and you aren't is that I have failed more often than you have."

    It is sad but true that our greatest lessons come from our greatest failures.The important thing is the lesson. There is no such thing as failure as long as there is a lesson to be learned.

    Learn something new every single day. Three very good reasons for becoming a lifelong learner include promoting your brain's health, giving your life a sense of purpose and promoting your financial security. Any one of these reasons should be enough, but all three combine to a powerful motivation to learn.

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.
