A strong memory depends on the health and vitality （活力） of your brain. They say that you can't teach an old dog new tricks, but when it comes to the brain, scientists have discovered that this old saying simply isn't true. {#blank#}1{#/blank#}

      Give your brain a workout. Memory, like muscular strength, requires you to “use it or lose it”. The more you work out your brain, the better you'll be able to process and remember information.{#blank#}2{#/blank#}

        Don't skip the physical exercise. While mental exercise is important forbrain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brainstay sharp. It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.

        Get enough sleep. There is a big difference between the amount of sleep you can get by on and the amount you need to function at your best.{#blank#}3{#/blank#}Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys braincells. Studies have also linked stress to memory loss.

        Have a laugh.{#blank#}4{#/blank#} That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specificareas of the brain, laughter engages multiple regions across the whole brain.

{#blank#}5{#/blank#}Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains, “healthy”fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it's not just what you eat—it's also what you don't eat.

A. Eat a brain-boosting diet.

B. Play games with memory.

C. Laughter is the best medicine.

D. But oversleeping is not good for yourbrain.

E. Even skipping a few hours makes adifference!

F. You have to shake things up from timeto time!

G. The human brain has an astonishingability to adapt and change.

    Recently some articles claim the word “selfie” as one of the most annoying words. But I'd like to offer that maybe it isn't not so bad.

    The “selfie” is used to describe the self taken photo, often from a smart phone. Women and men alike adorn their Instagram, Facebook and Twitter accounts with these pictures, sometimes with puckered lips or large smiles. In fact, the selfie has become so widely known that over 31 million photos on Instagram are captioned with the selfie.

    Let's think about it. Someone takes about 10 seizes each time they do, and they only end up posting one or two of those. They pick the one that they feel makes them look the best. Isn't that beautiful? In that one picture, someone has even him or herself confidence.

    Self-image is important. In society today, we are so often consumed with what society tells us is perfect. But maybe, with that one selfie, we feel like we fit that bill. We feel handsome, beautiful, confident, smart, happy and content. For that moment, everything bad or terrible that has ever happened to us is erased, because that smile or that pucker is what gives us the determination to love ourselves.

    I saw a spoken word poem recently and the young man said: If I ask you what you love the answers will most likely roll off your tongue. You love to read. You love to write. You love birds, music, tattoos… Your mom, your brother, your sister, your daughter, your best friend, your dog. How long do you think you could go on and on before you said “I love myself”？

    That statement hit me like a ton of bricks. I've struggled with confidence all of my life. I still do. And in no way am I saying that taking a selfie is a gateway to that confidence. However, the selfie does deserve some credit for allowing individuals to express themselves. Pamela Rutledge agrees, stating, “There are many more photographs available now of real people than models.”

    Computers have beaten human world champions at chess and, earlier this year, the board game Go(围棋). So far, though, they have struggled at the card table. So we challenged one AI(artificial intelligence) to a game.

Why is poker so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an “information incomplete” game. Players have to guess opponents' hands from their actions—-tricky for computers. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

    Scientists believe it is only a matter of time before AI once again vanquishes humans, so our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, a researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

    Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

    Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

    After two hours of quite defensive play, from the computer at least, we called it a draw.

    While both Europe and the United States of America are considered the Western world, it's good to know there are some differences in culture. If you are considering moving to a European country, you will find the information below helpful as you plan your move.

    One cultural difference is how the countries perceive（感知）time and space. For example, a house in the United States that is 200 years old would be considered ancient. This is probably because America is a fairly young country. However, in Europe, something would not be considered ancient unless it was at least 2,000 years old. However, perception of distance seems to be the opposite. While Europeans would consider 100 kilometers a long way to drive, Americans would think twice. This could be due to the fact that Europe is smaller and more heavily populated. In fact, the United States is over twice the size of Europe.

    Cars are another factor that differs greatly between Europe and the United States. American automobiles usually have automatic transmissions（传动）while European cars generally have manual gears（手动变速器）. European automobiles are smaller and more round-shaped, while American cars are larger and more square-shaped. Trucks and limousine are vehicles that American enjoy. In Europe, however, these types of vehicles are hardly seen, as they prefer smaller cars due to parking and traffic congestion.

    The view of education is another cultural difference between the European countries and the United States. In America, parents may save for many years and even go into debt to pay for their children to attend college. Most schools and universities in Europe, however, are free of tuition. In fact, it is just expected for children to attend college there and not a privilege（特权）, as in the United States.
