Have you ever considered why you begin yawning too when you see someone yawn? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it whether or not we actually perform the same action. This explains a great deal about how, we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions, they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example: “The hand took hold of the ball” ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with even more information regarding how humans behave and interact. Indeed, it may turn out to be the equivalent (相等物）for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does — well, perhaps you'll understand why.

    If you need to spend time on the road，it's important to find ways to keep safe on your feet．Don't suppose it's your right of way. Yes，you might be crossing at the right place，at the right time，within the crosswalk area，but you are still exposed to danger. It could be a distracted driver，or a cyclist with a loose sense of traffic rules，so you could still get hurt．You can be in the right legally，but that won't be much help when you're in the hospital.

    Follow pedestrian(行人) signals. Just as drivers aren't supposed to speed up to beat a light when crossing through an intersection，pedestrians need to take the same care when obeying their own signals．If the hand is flashing and the countdown is into single digits (数字), stay where you are．Trying to outrun the flashing hand is unsafe，especially as cars try to clear the intersection before the light turns red．

    Give drivers enough time to stop when crossing. Don't suppose that drivers will jam on their brakes when you hit the crosswalk signals. Some provinces，such as Alberta, issue （发出）a ticket if you don't give drivers enough time to brake.

    Cross quickly. Once you've followed all of the other rules，and it is safe to cross the street，don't then just wander along in front of six lanes (车道) of traffic. There's no need to run or jog，but respect the drivers who respected you enough to stop for you.

    Do you find it difficult to put down your mobile phone?

    If yes, you're not alone. These days, many people suffer from the stress of FOMO (fear of missing out). They reach of their mobile phones when they wake up in the morning, and for the rest of the day, they constantly check their social media apps for the latest updates.

    Despite the convenience smart phones bring, many people struggle with their digital habits. This is why Google introduced an app called Dashboard for Android operating system. This new app includes well-being functions that aim to help users manage the time they spend on their digital devices.

    It all starts with a bird's-eye view. Dashboard allows users to look at all the details of their phone habits. For example, a user can see how many times they're unlocked their phone and how many times they're checked their social media apps, as well as how much time they spend on each app every day.

    Once the users see this information, they'll be able to make some changes. With the App Timer function, users can set a time limit for how long they can use each app for every day.

    But even if users become more mindful of their usage, they're still likely to be drawn in by notification（通知）. Such feature automatically（自动地）silences incoming calls and notifications when a user puts their phone face down.

    If people truly want to make full use of their free time instead of losing hours using their smart phones, these new functions are just one way of doing that.

    The easiest answer would be just to use your willpower.

    In the depths of the French Guianese rainforest, there still remain unusual groups of (土著的）people. Surprisingly, these people live largely by their own Laws and their own social customs. And yet, people in this area are in fact French citizens because it has been a colony of the French Republic since 1946. In theory，they should live by the French law. However, their remote locations mean that the French law is often ignored or unknown, thus making them into an interesting area of “lawlessness” in the world.

    The lives of these people have finally been recorded thanks to the effects of a Frenchman form Paris called Gin. Gin spent five months in early 2015 exploring the most remote comers of thin area, which sits on the edge of the Amazon rainforest, with half its population of only 250,000 living in its capital, Cayenne.

    “I have a special love for the French Guianese people. I have worked there on and off for almost ten years," says Gin. "I've been able to keep firm friendships with them. Thus I have been allowed to gain access to their living environment. I don't see it as a lawless Und. But rather I Me it as an area of freedom."

    “I wanted to show the audience a photographic record touching upon the uncivilized life," continues Gin. “I prefer to work in black and white, which allows me to show different specific worlds more clearly.”

    His black-and-white pictures present a world almost lost in time. These pictures show people seemingly pushed into a world that they were unprepared for. These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle offered by the modern French Republic, which bring with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.

    Any foreigner who has tried to learn Chinese can tell how hard it is to master the tones required to speak and understand. And anyone who has tried to learn to play the violin or other instruments can report similar challenges.

    Now researchers have found that people with musical training have an easier time learning Chinese. Writing in the online edition of Nature Neuroscience, researchers from Northwestern University say that both skills draw on the same parts of the brain that help people discover changes in pitch(音调).

    One of the study's authors, Nina Kraus, said the findings suggested that studying music "actually tunes our sensory system". This means that schools that want children to do well in languages should hesitate before cutting music programs, Dr. Kraus said. She said music training might also help children with language problems.

    Mandarin(普通话)speakers have been shown to have a more complex encoding(编码) of pitch patterns in their brains than English speakers do. This is because in Mandarin and other Asian languages, pitch plays a central role. A single­syllable word can have several meanings depending on how it is intoned.

    For this study, the researchers looked at 20 non­Chinese speaking volunteers, half with no musical background and half who have studied an instrument for at least six years.

    As they were shown a movie, the volunteers also heard an audio tape of the Mandarin word "mi" in three of its meanings: squint, bewilder and rice. The researchers recorded activities in their brain stems to see how well they were processing the sounds. Those with a music background showed much more brain activities in response to the Chinese sounds.

    The lead author of the study, Patrick C.M. Wong, said it might work both ways. It appears that native speakers of tonal languages may do better at learning instruments.
