    Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list. you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. {#blank#}2{#/blank#} A weekly schedule may not solve all your problems, but it will force you realize what is happening to your time.

    Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of eeverything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.

    Make good use of your time in class. {#blank#}3{#/blank#} Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.

    Study regularly. When you get home from school, go over your notes, review the important points that your teacher is going to discuss the next day, read that material. {#blank#}4{#/blank#} If you do these things regularly, the material will become more meaningful, and you'll remember it longer.

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!

    Traveling to all corners of the world gets easier and easier. We live in a global village, but this doesn't mean that we all behave in the same way.

    How should we behave when you meet someone for the first time? An American shakes your hand firmly while looking you straight in the eye. In many part of Asia, there is no physical contact (接触)at all. In Japan, you should bow, and the more respect you want to show, the deeper you should bow. In Thailand, people greet each other by pressing both hands together at the chest. In both countries, eye contact is avoided as a sign of respect.

    Many countries have rules about what you should and shouldn't wear. In Muslim countries, you shouldn't reveal (显露)the body, especially women, who Should wear long blouses and skirts .In Korea, you should take off your shoes when entering a house. Remember to place them neatly together where you came in.

    In Spain, lunch is often the biggest meal of the day, and can last two or three hours. For this reason many people eat a light breakfast and a late dinner. In Mexico, lunch is the time to relax, and many people prefer not to discuss business as they eat .In Britain, it's not unusual to have a business meeting over breakfast.

    In most countries, an exchange of business cards is necessary for all introductions. You should include your company name and your position. If you are going to a country where your language is not widely spoken, you can get the back side of your card printed in the local language. In China, you may present your card with the writing facing the person you are giving it to.

    In an ideal world, we usually get eight hours of sleep every night, and wake up with enough energy before work. But when we're struggling to balance the responsibilities of everyday life, cutting back on sleep seems to be the only solution. Many of us rely on coffee or energy drinks to get us through the day, instead of making sleep a priority. Sadly, as delicious as it can be, caffeine is not the solution. Being tired not only brings down our energy levels, but also makes us less productive and less motivated. There are concrete steps you can take right now to renew your energy.

    Awareness comes first because you have to understand what's going on before you can do anything to change it. Most of us are too busy to notice how fatigue(疲劳) really affects our bodies and minds. What signs of trouble do you regularly display? The patterns of your signs of trouble can give you clues about the negative effects of your fatigue. In addition, it's wise to start thinking about whoever can feel the effects of your fatigue.

    Reflecting on the choices you've made can provide clarity, which will help you figure out what needs to be changed. During this reflection, you will be able to understand more about yourself and why you do the things you do. You may decide to forgive yourself for the mistakes you've made. Thinking about the positive aspects of your life will make you feel refreshed and ready to move forward.

    Conversing with others not only provides support, but also leads to new perspectives and feedback that can help with treatment and what you need to heal. To start with, have an open mind and an open heart. Limit complaining. Complaints may need to be aired in order to relieve pressure, but if they dominate(占上风), anger will win. Tell the truth. You do not need to tell people everything, but you do need to be honest. Listen carefully because it shows respect.

    The fourth step is about renewal—getting rid of what is bringing you down and making a fresh start. It's helpful to break the process down. It is easier to make small adjustments than big ones. On occasion, the small steps alone can remove fatigue. For instance, you may not need to change your career but change emphasis. If you feel hopelessly dragged down by fatigue, self­care may be the best prescription.

AlphaZero--an Updated Model of AI

    Soon after Garry Kasparov, the former world chess champion, lost his rematch against IBM's Deep Blue in 1997, the short window of human-machine chess competition slammed shut forever. Unlike humans, machines keep getting faster, and today a smartphone chess app can be stronger than Deep Blue. However, as people see with the new AlphaZero system, machine dominance has not ended the historical role of chess as a laboratory of cognition.

    Much as airplanes don't flap their wings like birds, machines don't produce chess moves like humans do. Based on a generic algorithm (算法), AlphaZero incorporates deep learning and other AI techniques like Monte Carlo tree search to play against itself to develop its own chess knowledge. Unlike the traditional program Stockfish, which employs many preset evaluation functions as well as opening and endgame moves, AlphaZero starts out knowing only the rules of chess, with no preset human strategies. In a few hours, it plays more games against itself than have been recorded in human chess history. It teaches itself the best way to play, reevaluating the relative values of the pieces. It quickly becomes strong enough to win 28, draw 72, and lose none in a victory over Stockfish. Since AlphaZero can program itself, this superior understanding allows it to outclass the world's top traditional program despite calculating far fewer positions per second. It's the typical example of the cliché, "work smarter, not harder".

    AlphaZero shows that machines can be the experts, not merely expert tools. Explainability is still an issue—it's not going to put chess coaches out of business just yet. But the knowledge it produces is information humans can learn from. AlphaZero is surpassing humans in a profound and useful way, and researchers are working on transferring the knowledge acquired from AlphaZero to other fields.

    Machine learning systems aren't perfect. Even though great progresses have been achieved, AI algorithms are still struggling on open problems such as computer vision, natural language understanding... There will be cases where an AI will fail to detect exceptions to its rules. Therefore, as Kasparov writes, "We must work together to combine our strengths. I know better than most people what it's like to compete against a machine. Instead of raging against them, it's better if we're all on the same side."
