I live in the land of Disney, Hollywood. You may think people in such an attractive and exciting, fun-filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness.

    Many intelligent people still consider happiness equal to fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more lasting emotion.

    Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends.

    I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful people have constant access to glamorous parties, fancy cars, expensive homes, everything that brings “happiness”. But in memoir after memoir, famous people expose the unhappiness hidden beneath all their fun — depression, alcoholism, drug addiction, broken marriages, troubled children and extreme loneliness.

    Ask an unmarried man why he refuses to get married even though he finds dating to be less and less satisfying. If he's honest, he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure and excitement. Marriage has such moments, but they are not its most distinguishing features.

    Similarly, couples that choose not to have children are deciding in favor of painless fun over painful happiness. They can dine out whenever they want and sleep as late as they want. Couples with babies are lucky to get a whole night's sleep or a three-day vacation. I don't know any parent who would choose the word fun to describe raising children.

    The way people stick to the belief that a fun-filled, pain-free life equals happiness actually reduces their chances of ever achieving real happiness. If fun and pleasure are equal to happiness, then pain must be equal to unhappiness. As a result, they fear the pain unavoidably brought by such things as marriage, raising children, professional achievement, religious commitment and self-improvement.

    But, in fact, the opposite is true. More times than not, things that lead to happiness involve some pain. The very efforts are the source of true happiness. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations we can ever come to.

    I don't think there is anything more important than health. “Health is the greatest wealth，” wise people say. You can't be good at your studies or work well when you are ill.

    If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that, he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.

    Speaking about doctor's advice, I can't help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: "Eat with pleasure, drink with pleasure and enjoy life as it is." The doctor also said that if the man wanted to be well again, he shouldn't smoke more than one cigarette a day. A month later the gentleman came into the doctor's office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man." But you know, doctor," he said, “it's not easy to begin smoking at my age.”

    It's OK to say you've never heard of grime (伦敦地下音乐) - unless you're from the UK. That's because this music type was invented in the UK in the early 2000s.

    To someone who's not familiar with underground music culture, it's easy to get confused between hip-hop and grime since they are both noisy. And many people didn't bother to tell them apart，until earlier this month when grime stars like Stormzy and J Hus led this year's Mobo – “music of black origin”, an award in the UK. Just like UK electronic music and hip-hop, from which grime drew influence, it mostly reflects the thoughts of young people. But different from hip-hop, grime singers sing in dialects with strong accents, giving a special flavor to their songs.

    Lady Leshurr，known as the “Grime Queen”, said that she once tried to hide her accent, as she didn't want people to judge her. But one day, she realized that she didn't need to change herself just to please others. And there's no doubt that this is the soul of grime music: be yourself.

    Grime has challenged modem music in its production beauty and its expressions. Also different from the hip-hop culture, which usually focuses on being rich, grime singers pay more attention to social phenomena like those who suffer from disasters and the gap between the rich and poor.

    Although still quite a young music type, grime seems to be getting loved by more and more people. In 2016, the English grime artist Skepta won the Mercury Prize with his album Konnichiwa, beating big names like David Bowie and Radiohead.

    However, no matter whether grime is one day accepted widely or not, one thing is for sure: in grime, singers always stay true to themselves.

    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to

    Frank, Aged 21

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!

    Eddie, Aged 20

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    David, Aged 19

    I'm not going to lie. The first day is kind of frightening (令人恐惧的). But you'll get used to it. Don't be afraid of anyone. Upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

WISH YOU WERE MORE CREATIVE?

    I want to ask you a favor. I have a pair of pants. Tell me: How many different ways can I put a pair of pants to use? Now imagine you're an architect. Same question. Now imagine you're Bill Gates. A scuba diver. A medieval knight. You still have the pants. What alternative uses come to mind?

    What you just practiced--the conscious act of "wearing" another self-is an exercise that, according to psychiatrist SriniPillay, MD, is essential to being creative.

    One great irony (讽刺) about our collective addiction to creativity is that we tend to frame it in uncreative ways. That is to say, most of us marry creativity to our concept of self: Either we're "creative" or we aren't, without much of a middle ground. "I'm just not a creative person!" a discouraged student might say in art class, while another might blame her talent at painting for her difficulties in math, making a comment "I'm very right-brained."

    Dr.Pillay, an assistant professor at Harvard University, has spent years overturning these ideas. He believes that the key to unlocking your creative potential is to challenge the stereotyped (陈词滥调的) advice that urges you to "believe in yourself." In fact, you should do the opposite: Believe you are someone else.

    He points to a study showing the impact of stereotype on one's behavior. The authors, psychologists Denis Dumas and Kevin Dunbar, divided their college student subjects into two groups, instructing one group to think of themselves as "eccentric poets" and the other to imagine they were "rigid librarians". The researchers then presented them all with ordinary objects, including a fork, a carrot, and a pair of pants, and asked them to come up with as many different uses as possible for each one. The former group came up with the widest range of ideas, whereas the latter had the fewest.

    These results suggest that creativity is not an individual characteristic but a "product of context and perspective". Everyone can be creative, as long as he or she feels like a creative person.

    Dr. Pillay's work takes this a step further: He argues that simply identifying yourself as creative is less powerful than taking the brave, creative step of imagining you are somebody else. This exercise, which he calls psychological Halloweenism, refers to the conscious action of "wearing" another self. An actor may employ this technique to get into character, but anyone can use it. According to Dr. Pillay, it works because it is an act of conscious unfocus, a collection of brain regions that spring into action when you're not focused on a specific task or thought. Most people spend nearly half of their days in a state of "unfocus." This doesn't make us lazy; it makes us human.

    Imagining yourself in a new situation, or an entirely new identity, never felt so productive. You're making yourself more creative, and you're giving yourself permission to do something you'd otherwise feel guilty about.

    Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

    The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

    FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

    And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
