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. .
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.
Don't skip the physical exercise. While mental exercise is important for brain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brain stay 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. .
Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys brain cells. Studies have also linked stress to memory loss.
Have a laugh. That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specific areas of the brain, laughter engages multiple regions across the whole brain.
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 your brain. E. Even skipping a few hours makes a difference! F. You have to shake things up from time to time! G. The human brain has an astonishing ability to adapt and change. |

A. How do they affect us? B. Emojis are real pictures. C. Why are emojis important? D. The invention of emojis changed that! E. This means that emojis have created a new brain pattern in us. F. The first emojis appeared on Japanese mobile phones in the 1990s. G. A written message is black and white, but an emoji adds emotions to our messages. |
When you write a message or an email, you might put a smiling face or other pictures at the end to make the message more fun. These pictures are emojis (表情符号). {#blank#}1{#/blank#} Later, they were used on Apple's iPhone and Android phones. Now they are everywhere!
Emoticon or emoji?
Before emojis, there were emoticons, which can be made from the signs you can find on your keyboard, for example: for a smiley. Emoji is a Japanese word which means photograph. e ("picture") + moji ("character"). {#blank#}2{#/blank#} There are all kinds of emojis, from faces and weather pictures to things in the kitchen and animals.
What are emojis for?
In English, we have a saying: A picture paints a thousand words. For many people, an emoji is like a punctuation mark, or smiling at someone across the room. {#blank#}3{#/blank#} It is like the tone (语气) of voice when we speak on the phone, or gestures used in conversation.
{#blank#}4{#/blank#}
When someone speaks and looks serious, we try to look serious, too, and when someone smiles, we smile as well. This is how we show empathy (共鸣) and make friends.
But when we are online, we can't see the person's face and there is no emotion. {#blank#}5{#/blank#} Scientists in Australia have discovered that when we look at a smiley face online, the same parts of the brain start working as when we look at a real smiley face. Our mood changes, and we try to change our face to match the emoji.
