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!

    Caffeine myth or caffeine fact? It's not always easy to know. Chances are you have some misunderstanding about caffeine. Read on. Here are some of the most common myths about caffeine and some facts have been gathered to shed light on them.

Myth one: Caffeine is addictive

    Caffeine is a stimulant(起刺激作用的食物) to the central nervous system, and regular use of caffeine does cause mild physical dependence. But caffeine doesn't threaten your physical, social, or economic health the way addictive drugs do. If you stop taking caffeine abruptly, you may have symptoms for a day or more, especially when you have been used to consuming two or more cups of coffee a day. However, caffeine does no cause the severity of withdrawal or harmful drug-seeking behaviors as drugs or alcohol. For this reason, most experts don't consider caffeine dependence a serious addiction.

Myth two: Caffeine probably causes insomnia(失眠症)

    Processed mainly through the liver, caffeine has a relatively short half-life. This means you can get rid of half of it within about five to seven hours on average. After eight to ten hours, 75% of the caffeine is gone. For most people, a cup of coffee or two in the morning won't prevent them from sleeping at night. Consuming caffeine later in the day, however, can interfere with sleep. Your sleep won't be affected if you don't consume caffeine at least six hours before going to bed.

Myth three: Caffeine harms children

    As of 2004, children aged 6 to 9 consumed about milligrams of caffeine per day. This is well within the recommended limit. However, energy drinks that contain a lot of caffeine are becoming increasingly popular, so this number may go up. Some kids are sensitive to caffeine, developing temporary anxiety or irritability, with a “crash” afterwards. Also, most caffeine that kids drink is in sodas, energy drinks, or sweetened teas, all of which have high sugar content. These empty calories put kids at higher risk for obesity. Even if the caffeine itself isn't harmful, caffeinated drinks are generally not good for kids.

Myth four: Caffeine has no health benefits

    Caffeine has few proven health benefits. But the list of caffeine's potential benefits is interesting. Any regular coffee drinkers may tell you that caffeine improves alertness, concentration, energy and clear-headedness. Scientific studies support these subjective finding. One French study even showed a slower decline in cognitive ability among women who consumed caffeine. Other possible benefits include helping certain types of headaches. These research findings are interesting, but still need to be proven.

    Sorry seems to be the hardest word. So sang Elton John on one of his biggest 1970s hits——but not every public figure seems to find it so tough to let out that powerful five-letter word.

    In recent months varieties of public figures, from politicians, to Hollywood actors and You Tube stars have all publicly expressed regrets.

    But with floods of regrets on the airwaves, just how can we tell a forced apology from a heartfelt expression?

    In its purest form, saying sorry should be an “act of regrets, a realization that something you have said or done has hurt someone and you want to repair it”, says psychologist Geraldine Joaquim.

    Made early, a sincere apology can be hugely beneficial and can “relieve the tension and takes the wind out of an accusers sails”, she says.

    A need to say sorry can arise in someone's public life and equally at home with their family and friends but, whatever the environment, how well it is received depends on how personalized it feels.

    From businesses, governments and organizations, a scripted response will fail to resonate (引起共鸣) as it will not convey empathy (同理心) and sympathy.

Whether online or in person, the timing and choice of language in an apology are decisive factors.

    “It is important to show that you understand and sympathize,” says Martin Stone, of PR agency Tank, “It is vital that any business or individual making an apology understands the focus- is it sorry for the way it's acted or is it sorry that the complainant feels the way they do?” Performed apologies always have a sense of being “acted out, and are often accompanied by too many theatrical gestures. If sincere, the person making the apology will be looking for listening clues to see if they are being understood, such as eye contact and facial expressions. They will provide “humbling (谦卑的) signals”, such as a lowered head, to indicate regrets.

    It is also important to avoid irresponsible statements or promises that can't be kept. “Don't say that you'll ensure that this will not happen again if you're not confident it won't. It could come back to bite you,” Stone explains.

    Equally, the use of “but” can hugely change the tone of an apology.

    As Stone points out. 'I'm sorry but... It sounds like you are making excuses and aren't actually taking any form of responsibility. It may be three letters but it can instantly make an apology seem hollow,”

    Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.{#blank#}1{#/blank#}

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.{#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right.{#blank#}4{#/blank#} The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

    If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#} "You keep what matters," Tononi says.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. That's why students do better in tests if they get a chance to sleep after learning.

D. Similarly, when people go for a few days without sleeping, they get sick.

E. The processes take place to stop our brains becoming loaded with memories.

F. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.

G. "Sleep is the price we pay for learning," says Giulio Tononi, who developed the idea.

The North Star

    Among the pile of stars in the universe, there are a couple that are of great importance to people on Earth. The sun, of course, is one of them. The other is known as Polaris, the North Star. {#blank#}1{#/blank#} Therefore, it is a great compass(指南针).When people in the northern part of Earth look toward Polaris, they can be certain that they are facing north. The permanence of Polaris in the north sky has helped countless people find their destinations.

    Before the invention of modern navigation tools, sailors relied on Polaris. From the top of their ships, sailors would look for Polaris to figure out their place at sea. They figured out the angle between the star and the horizon to determine their latitude(纬度). As long as the equations were not wrong, the results were very reliable. Polaris also let sailors determine North, South, East, and West. {#blank#}2{#/blank#}

    To those who sail at night, changeable storms and dark clouds were more than annoying things.{#blank#}3{#/blank#} It's possible for a captain to make an accidental wrong turn. The ship could become stranded at sea, and the frustrated captain would have no way to get the ship back on the right course. The sailor's fears wouldn't be relieved until the clouds cleared and Polaris came back into view. Even today, sailors sometimes choose to steer by using Polaris on clear nights.

    {#blank#}4{#/blank#} The Big Dipper, a constellation that is well known in astrology, appears to revolve around Polaris. The handle of the Big Dipper always points to the North Star. When people get lost, it's comforting to know that their problems can be relieved by looking at the sky.

A. It's not difficult to tell the Polaris apart from the pile of other stars in the universe.

B. People who are lost can be relieved by gazing up at Polaris.

C. By knowing directions and their location, sailors could easily steer their ships.

D. They could destroy entire journeys by blocking the view of Polaris.

E. It's certain that the Polaris is part of a constellation(星座), which is not far from it.

F. It is special because it is the only star that always appears to be in the same place in the sky.
