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!

    Have you ever heard of homecoming? It's a tradition celebrated every year in the US. At homecoming, a school or university welcomes back former students or alumni(校友).{#blank#}1{#/blank#}It means, “coming home.”

    This is a time when everyone can get together.{#blank#}2{#/blank#}There are events that encourage school spirit all throughout homecoming week, which leads to the big day on Friday.

    A major activity that most students will take part in is choosing the homecoming king and queen.{#blank#}3{#/blank#} This is a group of boys and girls who represent (代表) school spirit. At the end of the week, students vote for a boy and a girl to be the king and the queen.

    Then it's time for the football game, the main event of homecoming week! {#blank#}4{#/blank#}Almost everyone from school goes to the game: students, parents, teachers, and alumni visitors. If they win, everyone is very happy.

    {#blank#}5{#/blank#} Students dress up, and some might even bring a date to go with them. After the dance, homecoming is officially over, and everyone can't wait for next year!

A. The last event is the homecoming dance.

B. That is where the name comes from.

C. Students get to pick who will be on homecoming court early in the week.

D. The tradition began more than 100 years ago in the United States.

E. The football team faces a lot of pressure to do well for the big crowd.

F. Homecoming usually lasts a week and happens in the fall.

G. Homecoming week was not just about fun, but also a chance to try out new things.

    If you are hungry,what do you do?Grab a piece of your favorite meal and stay quiet after that?Just like your stomach,even your mind is hungry.But it never lets you know,because you keep it busy thinking about your dream lover,favorite star and many such absurd things.So it silently began to pay careful attention to your needs and never let itself grow.When mind loosens its freedom to grow,creativity gets a full stop.

    This might be the reason why we all sometimes think “What happens next?”,“Why can't I think?”,“Why am I always given the difficult problems?”Well this is the result of our own karma（宿命）of using our brain for thinking of not-so-worthy things.

    Hunger of the mind can be actually settled through extensive reading.Now why reading and not watching TV? Because reading has been the most educative tool used by us right from the childhood.Just like that to develop other aspects of our life,we have to take help of reading.You have innumerable number of books in this world which will answer all your "How to?" questions.Once you read a book,you just don't run your eyes through the lines,but even your mind decodes（解码）it and explains it to you.The interesting part of the book is stored in your mind as a seed.

    Now this seed is unknowingly used by you in your future to develop new ideas.The same seed if used many times,can help you link and relate a lot of things,of which you would have never thought of in your wildest dreams! This is nothing lout creativity.The more the number of books you read,the more your mind will open up.Also this improves your speaking skills to a large extent and also makes a significant contribution to your vocabulary.Within no time you start speaking English or any language fluently with your friends or other people and you never seem to run out of the right words at the right time.

    A long time ago, soldiers fought wars on foot. Then they began to ride horses to battle. Until the invention of the stirrups (马蹬), though, men could not fight well with swords or spears while on horseback.

    Without stirrups, soldiers had no place to put their feet. They could not stand up to use their swords without falling off their horses. They could throw spears only with the force of their arms.

    Using stirrups, a soldier could stand up in his saddle (鞍). He could put a spear under the top part of his arm and charge with the force of his horse. He could use force when fighting with a sword. And he could win most fights against soldiers who did not use stirrups.

    The first stirrups were made in India. Because the weather was warm, people did not wear shoes. The Indian stirrup was made of rope. It fit around the big toes. Later, the Chinese made a foot stirrup of wood. Because the Chinese lived in a colder country, the stirrup had to fit around shoes. Still later, around A. D. 700, soldiers in Asia used strong iron foot stirrups.

    We often seek food after focused mental activity, like preparing for an exam. Researchers guess that too much thinking consumes a lot of energy from the brain. So the brain, sensing that it may soon require more calories to keep going, apparently leads to bodily hunger, and even though there has been little physical movement, we eat.

    The researchers note that tiring activity both increases the amount of blood sugar and lactate(乳酸盐)circulating in the blood and increases blood flow to the head.

    Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow of fuel—rich blood during exercise could feed a worn—out brain and reduce the urge to overeat.

    Thirty—eight healthy college students were invited to determine their fitness and metabolic(新陈代谢)rates and to report what their favorite pizza was. Afterward, they sat quietly for 35 minutes before being given as much of their favorite pizza as they wanted. At a later date, the volunteers returned and spent 20 minutes making selections from college and graduate-school entrance exams.

    Next, half the students sat quietly for 15 minutes, before being given pizza. The rest of the volunteers spent those 15 minutes doing intervals on a treadmill(跑步机)two minutes of hard running followed by about one minute of walking, repeated five times. These students were then allowed to gorge on pizza, too. But by and large, they did not overeat.

    When the researchers factored in(将……作为因素考虑)the calories burnt on running, they determined that those students actually consumed 200 fewer total calories after their brain workouts than the resting students.

    The researchers do not know if the runners consumed extra calories at dinner. They also cannot tell whether other types of exercise would have the same effect as running, although the researchers say they suspect that if an activity causes someone to break into a sweat, it should also increase blood sugar and lactate, feeding the brain and weakening hungers call.

A rainy day can be a chance to recharge. While you relax on the sofa with a movie, the raindrops falling on your windows might one day provide the power for your TV. This is the idea behind an invention that harvests energy from water. 

The technology is based on the triboelectric (摩擦电的) effect. An engineer at the University of Hawaii, David Ma knew that it was possible to generate electricity by rubbing two things together. So, he thought, "Why don't we use water?"

A drop of water sliding across a surface coated with two different materials would generate enough friction(摩擦) to create an electrical charge. By placing metal wires that the drop of water touched as it moved, it should be possible to harvest electricity, he reasoned. 

It worked. In fact, the researchers lit up 15 LED bulbs with a single moving water drop. 

This is not the first time that scientists have got electricity from water-generated friction. Earlier experiments, though, harvested the charge produced in a surface by a sliding drop of water. There, the surface had acted as an electrode(电极). This is different. The energy of friction is being harvested from the water itself. 

"The technology could someday power phones, sensors or other small electronics," says Christopher Oshman, an engineer at the Colorado School of Mines. "This work is a step towards harvesting the energy of moving objects all around us, including ourselves, to power the electronic devices we use every day," he says. 

"Ma has shown that the technology can work in a lab," Oshman says. Next, the Colorado researcher would like to see it tried on a larger scale, such as on an umbrella.
