A mouse looked through a crack inthe wall to see the farmer and his wife opening a package: What food might itcontain? He was astonished to discover that it was a mouse trap!

    Retreating to the farmyard, the mouse declared the warning, “There is a mouse trap in the house, there is a mouse trap in thehouse.”

    The chicken clucked and scratched,raised her head and said, “Mr Mouse, I can tell you this is a grave concern to you, but it is of no consequence to me, I cannot be bothered by it.”

    The mouse turned to the pig and told him, “There is a mouse trap in the house.” “I am so sorry, Mr Mouse,”sympathized the pig, “but there is nothing I can do about it but pray; beassured that you are in my prayers.”

    The mouse turned to the cow, who replied, “A mouse trap, am I in grave danger, huh?”

    So the mouse returned to the house, head down and depressed to face the farmer's mouse trap alone.

    That very night a sound was heard throughout the house, like the sound of a mouse trap catching its prey. The farmer's wife rushed to see what was caught. In the darkness, she did not see that it was an evil snake whose tail the trap had caught. The snake bit the farmer's wife. The farmer rushed her to the hospital. She returned home with a fever. Now everyone knew to treat a fever with fresh chicken soup, so the farmer took his hatchet to the farmyard for the soup's main ingredient. His wife's sickness continued so that friends and neighbors came to sit with her around the clock. To feed them, the farmer but chered the pig. The farmer's wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow slaughtered to provide meat for all of them to eat.

    So the next time you hear that someone is facing a problem and think that it does not concern you, remember that when the least of us is threatened, we are all at risk.

    A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies, creating clean air for the city's mask-wearing people.

    An electromagnetic field（电磁场） will pullparticles（微粒） in the smog to the ground where they can be easily cleaned.

“It's like when you have a balloon which has static（静电） and your hair goes toward it. Same with the smog,” says artist Daan Roosegaarde.

    His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks.

    With its skies regularly covered by dirty gray smog, Beijing this week announced a series of emergency measures to handle the problem.

    Roosegaarde says an indoor model device has already proven it works and is confident that the results — with the help of a team of scientistsand engineers — can be replicated outside.

  “Beijing is quite a good place because the smog in Beijing is quite low. It lies in a valley so there's not so much wind. It's a good environment to explore this kind of thing.”

  “We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again.”

    Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a practical solution to Beijing's awful air pollution.

  “This is not the real answer for smog. The real answer has to do with clean cars, different industry and different lifestyles.”

    However, he hopes the project will make a “fundamental statement” by allowing the city's people to realize the difference between breathing clean and smog-filled air.

    I have never been a fan of the phrase, "No pains, no gains." I prefer the alternative version, "No pains, no pains!" When it comes to exercise, for example, I learned years ago that pushing through pain was more likely to lay me up with an aching back than to leave me feeling strong and healthy.

    But there are times when stressful situations actually do lead to greater happiness. A new study published in the Journal of Happiness Studies found that people who pursue (追求) goals that are tough to achieve feel more stress in the moment, but greater happiness in the aftermath particularly if they feel connected to others along the way.

    The researchers concluded that happiness increases when people develop greater competence in something and greater competence only comes when people keep on working through the stress-inducing phase of trying, fighting, and trying again to learn and grow. If the psychological needs to be autonomous or self-directed, and to be connected to others are met, the momentary stresses will be less acute, and the resulting happiness will be more lasting.

    This idea reminds me of another often quoted phrase, which I have heard in reference to challenging tasks, such as exercise —"Fill-in-the-blank-stressful-task is the worst thing to do, but the greatest thing to have done." In other words, suffering from the stress of an exercise class that leaves us feeling sweat-drenched shouldn't lead us to walk away from exercising. And if we can pass those stressful moments with a friend, colleague or family member who is trustworthy and supportive, all will be better.

    As I travel my positive path, I'm certainly not seeking out stress. But life will offer me plenty of it, whether I ask for it or not. My task is to choose wisely when and how to face it head-on, knowing that happiness awaits on the other side.

    Although many online personality tests are fun, only a few will really give you insight into who you are and what you are supposed to be doing with your life.

    At CareerPlanner. com we believe that each individual (个人), regardless of (不管)race or religion, has a purpose in life, and until you discover what your purpose is, you will not find true happiness, nor true job satisfaction.

    This doesn't mean you won't be successful. It just means you won't be happy until you are moving towards your true purpose.

    Unfortunately, our school system does very little to help students discover their true career. This is where online personality tests and career tests can help.

    Online personality tests and career tests can help you better understand what type of work you should be doing to achieve job satisfaction, happiness, and success.

    Personality tests are most useful in giving you insight into "how" your personality compares to others and "how" you like to work.

    In particular, if you frequently experience difficulty working with others, or getting their support and cooperation, a really good personality test would show you how to get along better.

    While personality tests are very useful at showing you how you like to work and how you like your work environment, they are not really designed to show you "what" type of work is right for you.

    That is where Career Interest Tests come in. Online Career Tests, such as the CareerPlanner.com offers will help you discover what your true interests are, and what type of work you will be passionate about.

    But back to personality tests. The most well-established personality tests are the Myers-Briggs Type Indicator R, and the Enneagram.

A school district in Michigan has banned all backpacks from school buildings, in response to growing safety concerns. 

Flint Community Schools announced last week that backpacks would be banned and the ban would be in place for the rest of the school year. The new policy went into effect on Monday. 

"We are doing all that we can to create a safe and secure environment for our scholars, families, teachers and staff," Superintendent (主管) Kevin Jones wrote in a letter posted on the school district's website. 

Jones cited growing threatening behavior happenings across the country, including weapons being brought to schools, as the reason for the backpack ban. 

"Backpacks make it easier for students to hide weapons, which can be taken apart and harder to identify than hidden in pockets, inside books, or under other items," he said. 

Following the shooting at Robb Elementary School in Uvalde, Texas, last May, where 19 students and two teachers died, schools began taking policies requiring students to use clear backpacks. However, Flint Community Schools have gone a step further and banned clear backpacks from school buildings, with the superintendent saying that it doesn't resolve the issue. 

"By banning backpacks altogether and adding an increased security presence across the district, we can better control what is being brought into our buildings," Jones said. 

Students are allowed to store personal items like wallets, keys, hygiene products (卫生用品) and phones in small purses, bring lunchboxes or place their gym clothes in clear plastic bags, all of which will be subject to searches. 

If a student brings a backpack to school, parents or guardians must pick it up from the school, according to Jones. 

The Flint Board of Education, the district's administration and headmasters approved the policy change, Jones said, adding that the district received support from the Flint Police Department. 

Humans aren't the only animals that move to music. Parrots have been known to do it. And now rats have been observed bopping their heads in time with the tunes of Mozart, Lady Gaga, Michael Jackson and others, according to a new paper from the University of Tokyo. What's more, the rats seems to respond to the same beats that get humans' feet tapping (轻跺). 

The researchers played a sonata by Mozart for lab rats at different variations of the original speed. Wireless sensors on the rats' bodies tracked their movements. Meanwhile, 20 human participants were involved and listened to the same music through headphones equipped with motion sensors. 

It was observed that the rats' head movements were the most obvious when the music played at its normal speed, which was around 132bpm (beats per minute). The same was true for human participants. The researchers then changed to some pop songs such as Lady Gaga's "Born This Way" and Michael Jackson's "Beat It". As with Mozart's, rats moved their heads along the rhythm of pop songs, similar to how people do, at about 120 to 140bpm. 

The study showed that both rats and humans moved their heads along to the beat in a similar rhythm. The level of head bopping from both humans and rats decreased as the music sped up. The study suggests that there is something similar about the way human and rat brains respond to rhythms, but rats do not match their motions to the beat like humans do. Humans can predict the timing of a beat and move predictably to it. 

Aniruddh Patel, a psychologist who studies brain response to music, says humans and parrots respond to beats with big, voluntary movements such as head shaking, dancing or foot tapping. Patel also stresses that this study does not show that rats have the same emotional associations with music as humans do. Yet he believes it could help reveal how humans and some other animals developed a sense of rhythm.
