Do you think you could learn a language in an hour?

    We know, we know! We would expect you to be skeptical. It's ridiculous to think you can learn a language in 60 minutes. You wouldn't even get through the As in a bilingual dictionary in that amount of time! Best-case situation: in an hour, most of us could probably stuff a few words and ready-made phrases into our short-term memory (with a high likelihood of forgetting it all by the following day). Accomplishing anything more than that in one hour? Impossible. Unless…

    We posed the one-hour language challenge to four polyglots(通晓数种语言的人) who are experts on how to study languages. To keep the challenge from becoming completely impossible, we gave them a bit of a break: to learn Romanian in one hour. Why Romanian? Because it's a Romance language and shares many similarities with the languages that the polyglots already know: French, Spanish, Italian, Portuguese. And to make sure their hour of learning was as effective as possible, all of them were assigned a personal Romanian tutor to help coach them on their way to success.

    Although each polyglot has a different technique for picking up and remembering a new language, all four methods offer valuable insights to anyone, from casual learners to hard-core language enthusiasts.

Alex Rawlings — UK

    "I'm a bit nervous. This is probably the craziest language-learning thing I've ever done, but learning languages has always been about fun. I expect that, after this, I'll be prepared to have a simple chat over a coffee in Romanian. Is that reasonable?"

    Method: Learn the verbs first

    With only an hour until he had to start demonstrating his grasp of Romanian, Alex knew he had to start talking quickly. He chose to focus first on commonly used verbs and how to conjugate（动词变形） them. Once he had some verbs down, he could start collecting nouns from his tutor and plugging them in to make more interesting and relevant sentences.

Luca Lampariello — Italy

    "Every time I have a conversation with native speakers, it really motivates me. Human contact is really important when learning a language."

Method: Start speaking right away

    Speaking doesn't mean speaking perfectly. Speaking even a little bit is a huge confidence boost. When you can say something in a new language and people actually understand you, it's very motivating. Yes, you'll make mistakes, but you'll also learn faster than if you try to get it all perfect in your head first.

Michael Youlden — UK

    "We all speak a variety of Romance languages which I think will help us get into Romanian quickly."

Method: Write everything down

    Language learning is about recall; there's no use learning something if you don't remember it. Speaking new words aloud is very important, but so is writing them down — after all, words exist as sounds and in written form. Taking notes is a proven way to put new vocabulary and grammar into your memory. Writing supports memorizing which supports speaking... it's a cycle. Plus, you have an easy reference when you want to review what you've learned.

Matthew Youlden — UK

    "I'm going to look for the patterns and similarities with languages I already know. We won't be able to speak fluently after an hour of study, but we should be able to get by with some basic vocabulary and phrases."

Method: Look for cognates

    Cognates are words in different languages that look and sound similar and have the same meaning, due to a common origin. Almost every language combination contains cognates (even if two languages aren't seemingly related), but languages from the same language family have many more. Whichever language you are learning, identify the familiar words and then use them to anchor the new words that aren't so familiar. To use English as an example, because it's a sort of Germanic-Romance hybrid, English already has many words that cognate with German, Dutch and Swedish on one hand, and on the other hand it also has lots of words that cognate with French, Spanish, Portuguese, Italian and, of course, Romanian!

    My parents were in a huge argument, and I was really upset about it. I didn't know who I should talk with about how I was feeling. So I asked Mom to allow me to stay the night at my best friend's house. Though I knew I wouldn't tell her about my parents' situation, I was looking forward to getting out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on.

    I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I'd stay with him until the power was restored. He was quite happy and said, “Great opportunity.”

    “What is it?” I asked.

    “To talk, you and I” he said. “To hold a private little meeting about what we're going to do with your mom and dad, and what we're going to do with ourselves now that we're in the situation we are in.”

    “But we can't do anything about it. Grandpa,” I said, surprised that here was someone with whom I could share my feelings and someone who was in the same “boat” as I was.

    And that's how the most unbelievable friendship between my grandfather and me started. Sitting in the dark, we talked about our feelings and fears of life — from how fast things change to how they sometimes don't change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be. Suddenly, the lights all came back on. “Well,” he said, “I guess that means you'll want to go now. I really like our talk. I hope the power will go out every few nights!”

    There's a trend that more city people decide that they want to grow crops and raise some live-stock (家禽). After all, there are few things more satisfying than biting into a bunch of tender, red carrots you grow yourself, or a fresh egg from the backyard.

    Most gardeners understand that the soil in big cities is often polluted with lead and know to get their soil tested. But most are pretty clueless about how to prevent other types of pollutants, like heavy metals and asbestos(石棉)from getting into their vegetables.

    Part of the problem is that “there might be pollutants that gardeners can't test for,” says Brent Kim, a program officer. Most soil tests look for lead, cadrniunt(镉)and arsenic(砷). But they don't test things like chemicals left behind by cars, which might have escaped into the soil.

    So if you're thinking of staring an urban garden, Kim says, once you've found a plot of land, you should learn what's now an empty plot or a backyard might once have been a parking lot, a gas station or a chemical ground. “Knowing its past will give you some idea about what might be in that soil,” he says.

    “People tend to think raised beds are going to solve their pollution problem,” Kim says. But polluted soil could easily kicked onto your plants, especially if the beds are low to the ground.

    “Another consideration is that you have to be careful about the materials that you're using to build a raised bed,” Kim says. Recycling wood from an old construction site might seem like a good, eco-friendly idea. But that wood could be treated with chemicals you don't want touching your fruits and veggies, Kim says. And it's always a good idea to use gloves while gardening, and wash all your produce thoroughly.

    “I see these urban growing spaces as these oases(绿洲)in the middle of these urban environments,” Kim says. “They bring communities together, and they help people save money on fresh produce. Urban growing spaces are amazing. Let's keep doing this, but let's do it safely.”

    In 1921, long before the Walt Disney Company turned Pooh (维尼熊) into an international star of TV and films, Christopher Robin Milne was given a toy bear on his first birthday from his father, A.A. Milne, who bought the stuffed (填充的) animal from a store. The stuffed animal was named Edward Bear. Years later, Edward was named Winnie. From the time Christopher Robin Milne was a baby until he was about 8 years old, he would receive different stuffed animals.

    A.A. Milne was a famous English author. As he watched his son interact (互动) with Winnie and friends, A.A. Milne thought his child's interaction with the collection of animals would make a great bedtime story. So Milne worked with artist Ernest H. Shepard and wrote the first Winnie the Pooh poem, where Edward Bear was known as “Teddy Bear”. The writings appeared in Punch magazine and in the book they wrote together, When We Were Very Young, which was published in 1924. In a four-year period, three more books that centered on the bear and his team followed: 1926's Winnie-the-Pooh; 1927's Now We Are Six; and 1928's The House at Pooh Corner.

    The books and poems about Pooh brought great success to the author, and the characters became favorites with young children and their families around the world. Their popularity led Disney to get the rights to make films about the characters in 1961. Five years later, Pooh, Tigger, Piglet and the rest of the team appeared on screen for the first time in Winnie-the-Pooh and the Honey Tree. The characters later appeared in TV shows, movies, video games and short films. Pooh's most recent appearance came last year in the popular children's program, Doc McStuffins, where he was a special guest.

    The day will come when renewable energy such as wind, solar, geothermal and others replace fossil fuels as the major source of world energy. However, most analysts insist that this day will not arrive for many decades to come—certainly well past the middle of the century. Systems of fossil fuels have already been firmly set up, and it is too costly or impractical to replace the existing systems with renewables. But there are good reasons to believe that the transition (转变) to renewables will come much faster than previously thought.

    It is hardly surprising that many experts say we will see a relatively slow transition from fossil fuels to renewables, given what is known about previous energy changes of this sort. "Energy transitions take a long time," observed Vaclav Smil of the University of Manitoba in Scientific American. It took more than 50 years for coal to replace wood as the world's leading source of energy and another 50 years for oil to replace coal; the change from fossil fuels to renewables, he argued, is not likely to come any faster.

    Under ordinary circumstances, Smil's forecast would no doubt prove accurate. But these are not ordinary times. Growing concern over climate change is leading to increasingly strict controls on CO₂ and other greenhouse gas (GHG) emissions (排放), while the development in renewables technology is lowering their price and speeding their installation.

    There are, of course, many difficulties in the effective control of carbon emissions, as demonstrated by coal companies to block the introduction of new rules by the US Environmental Protection Agency. Nevertheless, it is impossible to dismiss the progress being made at the local and international levels to promote the use of renewables. The European Union (E. U), for example, is well on the way to achieving a 20% reduction in GHG emissions from 1990 levels by 2020, along with a 20% increase in the use of renewable energy.

    The transition to renewables will be faster due to dramatic improvements in the pricing and performance of such systems. As a result of the steady increases in the efficiency of wind and solar systems, together with the savings achieved through large-scale manufacture, the price of renewables is falling globally. With prices dropping this fast, solar energy is now proving competitive with fossil fuels for generating electricity in many areas.

    The change from fossil fuels to renewable energy will not come overnight, and it will not escape many setbacks. Nevertheless, renewables are likely to replace fossil fuels as the main source of electrical power well before mid-century.

    The largest-ever study of the link between city walkability and high blood pressure has been considered as evidence of the "invisible value of urban design" in improving long-term health outcomes, say researchers. The study of around 430,000 people aged between 38 and 73 and living in 22 UK cities found significant connections between the increased walkability of a neighborhood and reduced risk of high blood pressure among its residents (居民).

    The results remained the same even after lifestyles and physical environment were changed, though the protective effects were particularly pronounced among participants aged between 50 and 60, women, and those living in heavily populated areas and poor neighborhoods.

    The paper was published in the International Journal of Hygiene and Environmental Health. With high blood pressure a major risk factor for chronic (慢性的) and particularly heart diseases, researchers at the University of Hong Kong and Oxford University said the findings showed the need to take notice of the health-influencing factor in urban design.

    "We are spending billions of pounds in preventing and curing heart diseases — if we are able to invest in creating healthy cities through small changes in the design of our neighborhoods to make them more activity-friendly and walkable, then probably, we will have significant savings in future healthcare expenses."

    Poorly designed spaces generally reduced walking and physical activity, promoting the lifestyles of long time sitting down and not moving, and were harmful to social communication, and as such related to poorer mental and physical health.

    Because walkability was “based on the potential (潜在的) design of the city", said Dr. Chinmoy Sarkar, cities could be adapted or designed to encourage it. “Such investments in healthy design are likely to bring in long-term gains as they are lasting and common."
