This may be music to your ears.

    Researchers P. Jason Rentfrow and Samuel Gosling gave 3,500 people a personality quiz. “We found that the musical styles people like are closely linked to their personalities,” Gosling says.

    RAP/HIP-HOP

    Known for their quick speech, some rappers can say more than 700 syllables（音节）a minute!

    If you like rap/hip-hop, you are energetic（精力充沛的）and have a way with words. You put a fresh spin on things, whether it's new moves on the dance floor or your hip style.

    CLASSICAL

    In the 18th century, classical musicians were like rock stars. Beethoven and Mozart, for example, played in crowded concert halls.

If you like classical, you are open to new ideas and like debating with friends. Creative and imaginative, you can easily spend many hours scrapbooking, writing or painting.

    COUNTRY

    Country music came from the folk songs of English, Scottish, and Irish settlers of the southeastern United States.

    If you like country, you express your opinions well, which makes you the ideal class president or team captain. Traditional and loyal, you enjoy spending time with your family.

    POP

    Pop music is designed to attract almost everyone, and it does. Each year, the industry brings in about 30 billion dollars!

    If you like pop, you are attractive to your friends. You can make big things happen, like planning for a huge party or inspiring your team to victory.

ROCK/ALTERNATIVE

    In the 1950s, rock music created a brand-new culture. Teenagers, for the first time, had an identity separate from adults and children.

    If you like rock/alternative, you are a risk-taker who never accepts no for an answer. You rise to any challenge, like doing very well in a big exam or landing the lead in the school play.

    If these personality profiles（人格剖析）don't match you, that's OK. These are just for fun.

    In general, people talk about two groups of colors: warm colors and cool colors. Researchers in psychology think that there are also two groups of people: people who prefer warm colors and people who prefer cool colors.

    The warm colors are red, orange and yellow. Where there are warm colors and a lot of light, people usually want to be active. People think that red, for example, is exciting. Sociable people, those who like to be with others, like red. The cool colors are green, blue and violet. These colors, unlike warm colors, are relaxing. Where there are cool colors, people are usually quiet. People who like to spend time alone often prefer blue.

    Red may be exciting, but one researcher says that time seems to pass more slowly in a room with warm colors than in a room with cool colors. He suggests that a warm color, such as red or orange is a good color for a living room or restaurant. People who are talking or eating do not want time to pass quickly. Cool colors are better for offices or factories if the people who are working there want time to pass quickly.

    Researchers do not know why people think some colors are warm and other colors are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue, and violet are cool. Perhaps warm colors remind people of warm days and the cool colors remind them of cool days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.

    What do Leonardo da Vincii, Marie Curie, and Albert Einstein have in common? They were all left-handed, along with other famous people including Brad Pitt Prince William, and Barack Obama. In fact, an estimated 13 percent of the world's population may be left-handed and still most people around the world are right-handed.

    What makes a person become right-handed rather than left-handed? As yet no one really knows for sure. One simple idea suggests that people normally get right-handedness from their parents. Studies have found that two right-handed parents have only a 9.5 percent chance of having a left-handed child, whereas two left-handed parents have a 26 percent chance of having a left-handed child. Another common theory is that left-handed people suffer mild brain damage during birth, which makes them left-handed. However, if this theory were true, it would not explain why the percentage of left-banded people is so similar in every society, when birth conditions vary so much from society to society.

    Whatever the reasons behind it, people's attitudes toward left-handedness have changed a lot over the years. Statistics show that although 13 percent of young people (10-20 years old) are left-handed, only 6 percent of the elderly are left-handed. Left-handed children used to be punished until they began using their right hand like other children, but today people who are left-handed are no longer looked down on nor are they considered abnormal. For most people today, either case is perfectly acceptable.

    When Cherry Watson travelled on a recent flight from New York to Washington and noticed an 'awful tension' in the cabin, she first thought it was caused by typical bad-tempered passengers. But as the flight neared its end, it became obvious that something was very wrong.

    A teenage boy with Down Syndrome (唐氏综合症) who was traveling with his family had become upset and would not return to his seat, regardless of the cabin crew's warnings over the loudspeaker that it was almost time to land. The pilot was forced to circle above the airport, delaying the landing and angering people on the already tense flight.

    'If it was a cartoon,' remembered Watson, 'there would have been smoke coming out of people's ears.'

    The boy's elderly parents and adult brothers and sisters tried to persuade him to get off the floor and back into his seat, but in vain. Watson, who used to be a teacher, stood up and quickly headed to the back of the plane.

    She found the boy in the passage between rows of seats, lying on his belly, and lay down on her stomach to face him. She began chatting calmly with him, asking his name, his favorite book, and his favorite characters. He told her he felt sick and she tried to comfort him.

    Minutes later, he allowed her to hold his hand, and then together they got properly back into airplane seats. Watson asked for sick bags, and held them as the boy threw up several times, including on her. As she helped him clean up, she repeatedly told him everything would be okay and that they'd get through it together.

    After the plane was finally able to land, no one was impatient to step off the flight as one might expect. Instead, calmed passengers—obviously following Watson's amazing example—allowed the boy and his family to depart first, smiling at them as they passed. His parents tearfully thanked Watson for what she had done, and a doctor sitting nearby also let her know he had even taken notes on her expert way of handling the situation.

    A humpback, a kind of big whale, can weigh as much as 40 tons and reach 50 feet from nose to tail. That means they can easily overturn small boats and it can be a great trouble to anyone who jumps on the back of the animal.

    But that was just what Sam Synstelien did when he saw a humpback in trouble in Central California's Morro Bay. The animal was hopelessly tangled (缠绕) in a rope that was attached to a buoy (浮标).

    Synstelien, along with his partner Nicholas Taron, had already tried reporting the poor animal to the U. S. Coast Guard—but they were told it would be hours before rescuers could come. Hours, the fishermen thought, this whale didn't have. "If we wanted the humpback to survive we had to go to get it," Taron later said. "We thought there was no other choice for the whale; we decided to go for it. We were so excited then. I don't think we were that scared. "

    It's easy for Taron to say, of course. His role in the rescue was mostly in the cheering department. In the video, you can hear him shouting "Swim! Swim! Move! Just get it! Get it!" from the side of the boat while filming the entire rescue. "The humpback was just swimming in circles," Taron said. "You could tell it was stressed and being held to the bottom."

    The very agitated whale didn't take well to human intervention (介入) and even hit the boat with its huge tail with a lot of force. But Synstelien hung in there, and at last cut through the rope. And then with a sudden move, the humpback swam deep down beneath the waves. It wasn't much of a thank you, but Synstelien and Taron were happy.

    I was in Walt Disney World with my son, Daniel, who is autistic (患自闭症的), and at that time he was 7 years old. My wife and our three other sons were with us too. He was having one of his melt down screaming tantrums (发怒), only God knows why. So my wife and I decided I would take the bus back to the hotel, and she would stay in the park with the other three children.

After we got on the bus, the screaming continued. My son looks "normal". To the many people on the bus, he appeared to just be a kid screaming — or a spoiled child who did not get his special toy that day. It did not take long — less than a minute — before the screaming brought about stares, then glares from the other passengers.

    To my shame, I found myself losing my temper at my own son. I was embarrassed, angry, and frustrated, and felt cheated by God for not being able to enjoy a normal vacation with my family because of him. I started to wonder what life would be like without having to deal with this cross (痛苦).

    And just as the reactions of the other passengers were becoming most intense, a man seated just in front of me turned around to face me. I cheered myself up for his advice on how to raise a well-behaved child.

    He said calmly, "Is he alright?" I said, "He's autistic." Then the man said, "It's alright." And he smiled. That's all.

    And suddenly, all the anger building up inside me was gone. I almost wept for shame at how I had felt a moment before. It no longer mattered what the other people thought. My son was my gift from God.

    I will never forget that man, nor his small, simple act of kindness and understanding. I truly believe he was my son's guardian angel that day maybe mine too.
