Have you ever found yourself in this situation：You hear a song you used to sing when you were a child-a bit of nostalgia（怀旧）or "blast from the past，"as we say．But it is not a distant childhood memory．The words come back to you as clearly as when you sang them all those years ago．

    Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language．They found that remembering words in a song was the best way to remember even one of the most difficult languages．

    Here is what they did. Researchers took 60 adults and randomly divided them into three groups of 20．Then they gave the groups three different types of "listen-and-repeat" learning conditions．Researchers had one group simply speak the words．They had the second group speak the words to a rhythm，or beat．And they asked the third group to sing the words．

    All three groups studied words from the Hungarian language for 15minutes．Then they took part in a series of language tests to see what they remembered．

    Why Hungarian，you ask ? Researchers said they chose Hungarian because not many people know the language．It does not share any roots with Germanic or Romance languages，such as Italian or Spanish．After the tests were over，the singers came out on top．The people who learned these new Hungarian words by singing them showed a higher overall performance．They did the best in four out of five of the tests．They also performed two times better than those who simply learned the words by speaking them．

    Dr．Katie Overy says singing could lead to new ways to learn a foreign language．The brain likes to remember things when they are contained in a catchy 3，or memorable 4，tune 5．

    Dr．Ludke said the findings could help those who struggle to learn foreign languages．On the University of Edinburgh's website Dr．Ludke writes，"This study provides the first experimental evidence that a listen-and-repeat singing method can support foreign language learning，and opens the door for future research in this area．"

    Russ Gremel, now 98 years old, decided it was time to donate $2 million to the Illinois Audubon Society, a charity to purchase nearly 400 acres of land for wildlife protection. Gremel was able to make this amazing donation because he purchased $1,000 worth of Walgreens stock seven decades ago whose value has grown recently.

    "A single man with no kids, Gremel has lived in the same Chicago house for 95 years, and has always lived simply", neighbor Patrick Falso told TODAY. Falso said he heard Gremel say many times the "money wasn't mine to begin with" and that he always intended to give it away.

    The Gremel Wildlife shelter was founded on June 4. Illinois Audubon Society president Jim Herkert said Gremel's donation was extremely generous. "It's allowing us to protect a really valuable and important possession and realize one of Gremel's wishes that we could find a place where people could come out and experience nature the way he did as a kid," Herkert told TODAY.

    After doing all this, this past weekend, Gremel adopted an old Chihuahua（吉娃娃犬）. Winnie the dog was picked up as a homeless dog several months ago. She suffered from a kind of cancer, which was treated—and all she needed was a loving home, which Colleen Collins, the founder of Perfect Pooches Adoption Agency, was determined to find.

    Gremel had lost his own beloved Chihuahua earlier this year. When he reached out to Collins about Winnie, she felt this could be a good match. That feeling grew when she brought Winnie to his house for a meet and greet, and Winnie was introduced not only to Gremel but also some of his friends and neighbors. One had brought over a lot of fresh strawberries; all said they'd be there to help out in any way needed.

    In the early decades of the United States, the agrarian(土地的) movement promoted the farmer as society's hero. In the minds of agrarian thinkers and writers, the farmer was a person on whose well-being the health of the new country depended. The period between the Revolution, which ended in 1783, and the Civil War, which ended in 1865, was the age of the farmer in the United States. Agrarian philosophers, represented most eloquently by Thomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a good society, their political virtue, and their Superior morality. And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy. Consequently, government at all levels worked to encourage farmers as a social group and agriculture as economic enterprise.

    Both the national and state governments developed transportation infrastructure, building canals, roads, bridges, and railroads, deepening harbors, and removing obstructions from navigable streams. The national government imported plant and animal varieties and launched exploring expeditions into prospective farmlands in the West. In addition, government trade policies facilitated the exporting of agricultural products.

    For their part, farmers seemed to meet the social expectations agrarian philosophers had for them, as their broader horizons and greater self-respect, both products of the Revolution, were reflected to some degree in their behavior. Farmers seemed to become more scientific, joining agricultural societies and reading the farm newspapers that sprang up throughout the country. They began using improved implements, tried new crops and pure animal breeds, and became more receptive to modern theories of soil improvement.

    They also responded to inducements by national and state governments. Farmers streamed to the West, filling frontier lands with stunning rapidity. But farmers responded less to the expectations of agrarians and government inducements than to growing market opportunities. European demand for food from the United States seemed insatiable. War, industrialization, and urbanization all kept demand high in Europe. United States cities and industries grew as well; even industries not directly related to farming thrived because of the market, money, and labor that agriculture provided.

    Although it's great to spend vacations seeing the world with family, friends, or a lover, traveling alone can also be completely incredible. A solo adventure has the potential to be life-changing. Here are some reasons you should travel alone at least once.

    If you enjoy meeting new friends, here's your chance; you will likely find some when traveling alone, Since you won't be focused on talking to anyone you know, you'll be more likely to strike up conversations with strangers. Meeting people from different backgrounds opens our minds, expands our world, and can inspire us a lot. You may meet some amazing locals or other adventurers like yourself; either way you're bound to make some new friends during your journey.

    A trip alone can ignite your creativity. Spending time alone with an open mind can be exactly what you need for your imagination to soar. Your enthusiasm and passion for life may sky-rocket from your awesome adventure.

    When traveling with a partner or a group, every idea can be bounced off someone else. When you travel alone, you will learn to be decisive; you will be making every decision alone. From where to eat, to what time to wake up, to what sights to see, and which airline to use, traveling solo forces you to rely on yours truly. As you realize you can make good choices without help from others, you will likely trust your instincts more, and this new found self-assurance and confidence will be helpful in many areas of your life.

    Although the idea of "zero emission net carbon-positive, sustainable (可持续)" development was promoted worldwide, most cities are at a loss what to do or even some have objected to it. But in Liuzhou, a city in southern China, attitudes could not be more different.

    The Liuzhou Municipality Urban Planning Bureau has signed up Italian architect Stefano Boeri, the father of the forest city movement, to build a self-contained community for up to 30, 000 people. He is the go-to man for such projects thanks to the success of his "vertical forests", two residential (住宅的) towers. Completed in 2014, they remove up to 17.5 tons of soot (煤烟) from the air each year, and a year later one of them was named Best Tall Building Worldwide.

    The Liuzhou project is a much more ambitious undertaking, however. Its homes, hospitals, hotels, schools and offices will be built on a 340-acre site in what Boeri calls the first attempt to create an "urban environment that is really trying to find a balance with nature". Its 100 species of plant life are expected to absorb almost 10, 000 tons of carbon dioxide and 57 tons of pollutants per year, while at the same time producing 900 tons of life-giving oxygen.

    Although the architects haven't published the cost of the forest city, the Milan towers cost only five percent more than traditional skyscrapers.

    The construction of his forest city at Liuzhou is set to begin in 2020, and there is still a great deal of planning and research required before a projected completion date can be set. However, Boeri remains optimistic about the project and has confidence in the soundness of his vision: "I really think that bringing forests into the city is a way to deal with global warming."
