When Hai started college, he weighed over 250 pounds Healthy food choices were difficult for him, and he was emotionally distraught (忧心忡忡). However, when he left home for college, he was able for the first time to start taking his life and weight into his own hands.

    He started by shopping at a local farmers' market, an experience that inspired him profoundly. The idea that a farmer's market represents local, sustainable, healthy food with a human connection where you can interact with the people that grow your produce was extremely appealing to him, and he began to think about the food that people at his university were eating. From what he saw at farmers' markets, Hai realized that dining hall food was not “real” food.A lot of it is frozen or processed, and has unhealthy additives. His ideas continued to develop as he started taking classes about food sustainability at university, and after the summer of 2014 during which he cooperated with other students9 he launched into his senior year at the University of California full force with the Real Food Challenge (RFC) campaign, a project he co-founded that aims to reinvest university spending in food that is “real”: ecologically-sound, community-based, humane, and fair; as opposed to those traditional purchases with those unhealthy additives and processed products.

    Not only has Hai started a movement of change across the university dining system, but he has also grown extremely as an individual，now with strong leadership abilities and great vision. In addition, after he started learning about food sustainability and taking action at university, Hai has lost over 100 pounds, and has been able to start enjoying activities such as backpacking and swimming that were not a possibility for him previously. He is confident instead of distraught now.

    A parent might place his daughter's drawing on the fridge out of a love for his child rather than for the wonderful image, but for many people, that children art is actually quite amazing. In fact, adult artists were often inspired by children's drawing. For the museum-goers out there who tend to point to a piece of modern art and say, “My kid could have made that !”It's worth remembering that often, that's actually just what the artist had in mind.

    For many kids, drawing is exciting not because of the final product it leads to, but because they can live completely in the world of their drawing for a few minutes. Even children are scribbling(涂鸦), they're representing through action, not through pictures. Liane Alves, a prekindergarten teacher, recalled a student who presented her with a drawing featuring a single straight line across the page. Alves assumed the child hadn't given too much thought to the drawing until he explained that the line was one of the stems (茎) from The Princess and the Pea, one of the fairy tales they read in class.

    Maureen Ingram, who's a preschool teacher at the same school,said her students often tell different stories about a given piece of art depending on the day, perhaps because they weren't sure what they intended to draw when they started the picture. “We as adults will often say, 'I'm going to draw a horse, 'and we set out. . . and get frustrated when we can't do it, ”Ingram said. “Children seem to take a different approach, where they just draw, and then they realize, 'it is a horse. '”

    And what about those odd or scary-looking drawings? Does that mean kids are telling themselves stories that are odd or scary? It's hard to say, but it's rarely a good idea to over-interpret it. Ellen Winner, a psychology professor, pointed to parents who worry when their kid draws a child bigger than the adults. What's most important to remember is that“children's art has its own logic,” Winner said. “Children are not being crazy. ”

    On November 24, 1868, Scott Joplin was born in Texas. He became famous as a ragtime (拉格泰姆音乐) composer and piano player. Ragtime music was an early form of jazz. This music has a lively beat and was developed from the music of African Americans.

    Ragtime became popular in the early 1890s, and the music was played on the piano. The piano player usually made up a melody, then changed it a little bit every time he played. Scott Joplin was very good at composing, or making up music and playing the piano. When he was growing up, Joplin's home was filled with music. Still, Joplin's father did not want him to be a musician. When he was about 14 years old, Joplin left home to travel and start a life of his own. He traveled all over the Midwest playing the piano and composing music. Sometimes he played with music groups. Other times he sang by himself in noisy saloons and bars. In 1899, Joplin wrote Maple Leaf Rag, a ragtime song that became a big hit and earned Joplin the title of The King of Ragtime. In all, he wrote more than 500 songs. Joplin's biggest dream was to compose a ragtime opera. Finally, after 10 years, Joplin completed a ragtime opera which he called Treemonisha. This opera was about a young black woman who became a leader of her people. She tried to help her people gain their freedom and their rights.

    1916, Joplin became very sick. He had a disease that made him forget things and become easily afraid of things. In 1917, he was put in the hospital. He finally died there on April 1, 1917. Scott Joplin's music became popular again in the early 1970s when it was used in a movie called The Sting.

    In 1963, at age 65, my grandfather, Erwin, decided to build a new house. He wasn't quite sure what to do with the old house since it sat where the new house would be. He finally hired a powerful vehicle to push it far out into a small group of trees. That old house sits there to this very day.

    Erwin and his wife, Elida, passed away, and I purchased the farm from their estate. My wife and I raised our sons on this place and have lived here for more than 30 years. When we first moved in, my wife took one look at the deserted house and declared it a hidden danger. I agreed and planned on a large bonfire. But I thought it appropriate to check out the house first, just in case something of worth had been left behind.

    I walked through the tall grass in the meadow where the old house sat. Time had worn it out. The entrance floor had fallen down on itself and most of the windows were gone. We entered through an open window. ①Here lay the reminders of my grandparents' lives: a broken chair, some old clothes ... But the thing that drew my eye was a cardboard box stuffed with papers. I dug through its contents and was instantly transported back in time. There was a tax return from 1957. Greeting cards from old friends and relatives, now all dead and gone. An uncle's third-grade spelling book. So sweet were the memories that the old house was spared the torch.

    As we hurried through our lives, my visits grew infrequent. I might catch a glimpse of the house through the trees and remembered how, as a child, I would struggle to walk in my father's footprints. Even then, I could imagine no nobler calling than farming, just like Dad. Then, one April morning, my father was felled by a massive heart attack, at age 68. The entire family was shocked by his passing, none more than me. Why I visited that old house on a day shortly after my father's funeral is still beyond me. It was as though it were calling; even the trees seemed to whisper an invitation to come, to visit, to stay awhile.

    ②As I stood once again on that ancient floor, my eye was drawn to a pile of papers on the floor. An envelope, yellowed with age, lay on top. A blue stamp on the envelope read "Passed by Naval Censor" How could I have missed this treasure? My father had served aboard the USS Washington during World War II and had written home whenever he could. My grandmother saved all of his letters.

    I removed one letter carefully from its envelope. ③It was dated September 1944. My father would have been somewhere in the South Pacific at that time and all of 18 years old. T studied the familiar handwriting. Dad wondered how the com harvest had been. He supposed that his youngest brother was starting first grade and imagined that he was becoming quite the little man. He asked his mother to greet everyone and said that he missed them all.

    It wasn't hard to read between the lines. Here was a homesick young man, a kid really, who had spent his entire life living upon a sea of flat land grass. Now he was on a different kind of sea, an ocean that was being disturbed by the thunder and the lightning of a world at war. At the bottom of the page, my father had passed on one last message. ④Tears burned my eyes as I read those words he had so carefully emphasized: "All is well here. Please don't worry. I am doing fine."

    As I left the old house that day, I took one last glance back at it over my shoulder. I don't care what any one thinks, I decided. That old house gets to stay there until it rots into the earth.

In the 1990s, a psychologist named Martin Seligman led the positive psychology movement, which placed the study of human happiness squarely at the center of psychology research and theory.

Since then, thousands of studies and hundreds of books have been published with the goal of increasing well-being and helping people lead more satisfying lives. But for over 40 years, self-reported measures of happiness have stayed stagnant (停滞的). Such efforts to improve happiness have been an ineffective attempt to swim against the tide, as we may actually be programmed to be dissatisfied most of the time. Why aren't we happier?

Part of the problem is that happiness isn't just one thing. Jennifer Hecht, a philosopher who studies the history of happiness, proposes that we all experience different types of happiness, which are not necessarily complementary Some types of happiness may even conflict with one another. In other words, having too much of one type of happiness may weaken our ability to have enough of the others. For example, a satisfying life is built on a successful career and a good marriage. It takes a lot of work and often requires cutting back on many of life's pleasures. That means we can't spend one pleasant lazy day after another in the company of good friends.

This difficult situation becomes more confused by the way our brains process the experience of happiness. A lot of evidence shows that most of the people possess something called the optimistic bias. They tend to think that their future will be better than the present.

Cognitive psychologists have also identified something called the Pollyanna Principle. It means that people process, rehearse and remember pleasant information more than unpleasant information. Why the good old days seem so good is because we focus on the pleasant stuff and tend to forget the unpleasantness. And if our past is great and our future can be even better, then we can work our way out of the unpleasant present.

Dissatisfaction with the present and dreams of the future are what keep us motivated. In fact, endless happiness would completely destroy our will. Among our earliest ancestors, those who were perfectly content may have been left in the dust.

Recognizing that happiness exists may help us appreciate it more when it arrives. Furthermore, understanding that it's impossible to have happiness in all aspects of life can help us enjoy the happiness that has touched us. Recognizing that no one "has it all" can cut down on the one thing that psychologists know prevents happiness: envy.

This year, the Music Educator Award, presented by the Recording Academy and Grammy Museum, went to Annie Ray, the performing arts department chair and orchestra director at Annandale High School in Fairfax County, Virginia. She attended the awards ceremony in Los Angeles and brought home both a $10,000 prize and matching grant （资助） for her school's music program.

Ray created the Crescendo Orchestra for students with severe intellectual and developmental disabilities, as well as a parent orchestra that teaches nearly 200 caregivers a year to play the same instrument as their children. She got the idea mostly from the Annandale community, which she says represents over 60 countries, including many refugees and immigrants. "There're many cultures that might typically clash, but they come together in this very beautiful harmony," Ray explained. "And that's really uniquely expressed in the orchestra classroom, where we're just all music-ing together."

Ray says the Crescendo Orchestra is focused on teaching students how to play an instrument, through one-on-one instruction tailored to their needs. The orchestra is about much more than just making music, however. "I really push my students to be brave and go outside of their comfort zone. We have to learn how to work together with others," she says.

Ray, who comes from a family of musicians and has played the harp （竖琴） since the age of five, knows firsthand the impact that a great teacher can make on their students. "Why I am where I am is because a teacher changed my life and made me want to be a music educator," she says.

Ray says her warm reception on the awards ceremony is especially meaningful because not many people understand what exactly music educators do in the classroom or how much their work matters. She says that lack of understanding is one of the biggest challenges facing the profession in general. Moreover, she says her school desperately needs new instruments, and adds that she'll use some of her grant money to buy more.
