If you will be cycling, you will need to know what these traffic signs and signals mean.

    A sign like this one means that there is a bike lane（道）. If there is a bike lane, you are required to use it. If there is not a bike lane, you should ride with traffic as far to the right side of the road as possible.

    When the signal light turns green, cars go. When you cross the street at a signal light, you should wait for the walk signal. Be sure to look carefully to the left, right and left again, before crossing the street.

    When the signal light turns yellow, car drivers should slow down and prepare to stop. You should not cross if the light is yellow. The light is about to turn red, and cars will enter the intersection(十字路口).

    This signal is the WALK sign. It has a picture of a person walking instead of using the word WALK.

    This signal is the DON'T WALK sign. It is part of the signal with the picture of a person walking. This is a picture of a red hand, meaning you should stop. You should wait to cross the street until the green picture of the person walking is showing.

    Car drivers and bikers must come to a complete stop at STOP signs.

    A yield sign means to slow down and be ready to stop. If there are pedestrians（行人）or vehicles in or nearing the intersection, you must stop. If there is no traffic in or nearing the intersection and it is safe, you may go through.

    This sign means you are coming to a crosswalk. Car drivers and bikers must stop to allow people in the crosswalk to cross the street.

    He may not have an "S" across his chest but this dog is most certainly a hero.

    Harley, who was rescued from a puppy mill four years ago, was named the American Humane Association's 2015 American Hero Dog. Harley, who is missing an eye and has other medical issues from his time at the mill, is now a "spokes-dog" against puppy mills. He serves as the adorable furry face of the "Harley to the Rescue" campaign, which raises funds for the National Dog Mill Rescue, according to a press release.

    The pup was rescued back in 2011 and adopted by Rudi and her husband, Dan. "It was just four years ago that he was pulled from the cage in the puppy mill and left to die," Harley's owner, Rudi, said during the awards show at the Beverly Hilton Hotel in Los Angeles this past weekend, according to Today. com. "We never would have ever thought he would live this long and make such a difference for so many puppies."

    The dog was one of eight finalists up for the American Hero Dog and was chosen as the winner through public votes. The finalists all won $ 1,500 to be donated to one of American Humane Association's charity partners, with Harley receiving another $ 5, 000 to go toward his charity partner, New Leash On Life.

    According to the release, Harley spent 10 years at the puppy mill, and endured rough treatment there, which led to his many medical issues. He lost his eye as a result of his cage being power-washed with him inside.

    The dog isn't just the face of his campaign, he also goes on rescue missions and makes public appearances at events and schools to raise awareness for puppy mills.

    This incredible work is all due to the dog's fighting spirit. That spirit is allowing him now to be the voice for dogs who cannot speak for themselves and give everybody hope that tomorrow's going to be a better day.

    Every time a new year is coming, people set out to better themselves. They promise they will lose weight, find a new job, or maybe even take that vacation they've always talked about. But why do we make these promises to ourselves, and where did this tradition come from? Why does this tradition live on when so many people fail to keep the resolutions(决定) they made? Well, we can start by blaming the ancient Babylonians.

    Around 4, 000 years ago in Babylon, the earliest recorded celebration honoring the coming of a new year was held. Calendars weren't as they are today, so the Babylonians did it in late March during the first new moon after the Spring Equinox(春分). The festivities were meant for the rebirth of the sun god, but the Babylonians made promises in order to please their gods. They felt this would help them start the new year off well.

    Resolutions continued on with the Romans. When the early Roman calendar no longer synced(同步) up with the sun, Julius Caesar decided to make a change. He consulted with the best astronomers and mathematicians of the time and introduced the Julian calendar, which more closely represents the modern calendar we use today. Caesar declared January 1 the first day of the year to honor the god of new beginnings, Janus. The Romans celebrated the New Year by offering sacrifices to Janus.

To this day, the traditions of the ancient Babylonians and Romans continue around the world. So much that Google launched a Resolution Map in 2013 where people could add resolutions and see others adding theirs in real time. However, no matter how many people participated in Google's project, the numbers are bleak when it comes to the number of people who maintain their resolutions—-only eight percent of people are successful in sticking them out.

    A retired United States soldier named Terry McGlade, who had served in Iraq and Afghanistan, his dog Major is a hero. He is specially trained to says sense when McGlade is about to have a seizure, get his phone and dial 911 for help.

    When Major had recently sensed an incident about to happen, and McGlade collapsed and hit the floor, Major was able to get to McGlade's phone, and more or less bite on the phone which is specially set up so that when multiple buttons are pressed and held in, it goes into emergency call mode, and dial 911.

    "He was actually able to get my phone out of my pocket," McGlade said.

    The 911 operators who got the call from Major said they never heard him bark or anything. However, they could hear what sounded like a confused man in the background, and did get quite suspicious after quite a few calls from McGlade's cell phone kept coming in. Quite clearly, Major was using his leg and also stepping on the screen to get the phone to díal for help.

    After Major was sure someone would be on their way to help, he then made his way out to the front of the house to wait. When police and ambulance arrived, he led them into the house and right to McGlade, still in distress.

    "I probably would have been in severe trouble if he wouldn't have called," McGlade said.

    McGlade was taken to the hospital, where he was kept overnight for observation, but thanks to his best friend, and now hero of the day, Major. He is feeling much better, and will make a full recovery with little risk of lasting damage from this particular incident.

The World's Largest Libraries

Most children love stories. Stories are entertaining and fun, but can they be more than just fun? Findings from a new study led by Rebecca de Leeuw, an assistant professor at the Radboud University, indicate stories in movies can also be meaningful for children. 

The researchers contacted children between 4 and 15years old after they watched the Disney film Inside Out. This film takes place mainly in the head of an 11-year-old girl, where her emotions—Joy, Sadness, Anger, Fear and Disgust, personified as different characters—conflict on how to help her best in her new life after her family moves. The story follows the "hero's journey" —a classical narrative（叙事的）framework, which involves a hero who goes on an adventure, overcomes challenges, and return s changed. So the research team chose this film. When making this film, the film-makers had in-depth discussions with psychologists to make the emotion animation consistent with scientific knowledge. 

The research team asked mostly open-ended questions to encourage the children to share their thoughts, including the key question: "Was there a part of the movie you had to think about?" Children looked at stills of important scenes and were invited to explain in their own words what happened. If they liked, they also rewatched scenes of the film. 

While watching, children made sense of the feelings, motives and behavior of characters in the film, using their social intelligence skills. They also further developed these skills when they were challenged in making sense of the story. Children also mentioned they appreciated seeing acts of pity, kindness, love and bravery in the film. Just like adults, they were even touched to tears by these qualities. 

One of the children in the study even expressed that Joy inspired her to never quit in her own life. The more insights children gained while watching, the more meaningful the story became for them. Altogether, stories in movies can be a quick way for children to gain life experience and wisdom.
