When I was about 12, I had an enemy, a girl who liked to point out my shortcomings (缺点). Wee k by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, then he asked. “Are the things she says true or not? Janet, didn't you ever wonder what you're really like ? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I went to a fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it. “That's just for you,” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”

    Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    Our “Mommy and Me” time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride the bikes up and down. “I wish I could take one of my children out alone,” said Christie.

    Then we worked out a plan: When Christie takes one of her children out, I'll watch her other three. And when she watches two of mine. I'll take someone out.

    The children were extremely quick to accept the idea of “Mommy and Me” time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. “She's like a different child when there's no one else around,” Christie shared with me quickly. With her mother all to herself, McKenzie didn't have to make an effort to gain attention.

    Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering (口吃的) son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And another son, Sam, who's always a follower when around other children shines as a leader during our times together.

    The “Mommy and Me” time allows us to be simply alone and away with each child-talking, sharing, and laughing, which has been the biggest gain. Every child deserves to be an only child at least once in a while.

The Power of Sound

The music of world-famous guitarist Gabriel Ayala can make you cheer or cry depending on the chords（弦）. As the winner of numerous musical honors, he said," I love the power of sound.

    He was also recently named Native American Music Awards Artist of the Year and he played at the inauguration（就职典礼）of President Barack Obama.

"My concerts are a journey for both my audiences and myself," he says. "Feelings and emotions are all over the board and I am the tool trying to convey those feelings, trying to paint a visual picture through chord changes. Sound conveys power, whether it's a well-performed craze or the wind blowing through the trees. Music isn't just a pretty melody also it's a visual performance that captures moments in life and puts them to music."

    Ayala also shares his gift with kids As a teacher with a master's degree he serves as an advocate（提倡者）for youth education by being a role model. He practices the philosophy of honoring elders, respecting women and loving children. He delivers a message lo youth that they can become whatever they dream of.

The music man has recently launched a non-profit foundation to work more closely with youngsters "I've been blessed in both my career and life and feel I need to give back to pay my respect and hanks for the gift I have owned and I can do that through music," he says.

    One of his experiences in giving back involved a high school class of some 200, which included a special needs group. I used my guitar as a tool to capture their interest and once I began playing, the whole behaviors of the class changed in a positive way. This was especially so for one of the disabled students whose hands would not allow him to even hold my costly guitar.

    When I put the valuable guitar in his lap and he started beating the heck out of it as hard as he could, there wasn't a dry eye in the house. That's the real reason I play music, not for fame or fortune but because music has the power to truly heal. The look on that boy's face was priceless.

    Scientists have been studying how people use money for long. Now they're finding some theories may apply to one group of monkeys.

    Researchers recently taught six monkeys hos to use money. They gave the monkeys small metal disks (圆片) that could be used like cash and showed them some yummy apple pieces. The monkeys soon figured out that if they gave one of the disks to a scientist, they'd receive a piece of apple in return.

    If you think that is all the monkeys can figure out, you are wrong. Two researchers, Jake and Allison, acted as apple sellers in the experiments. The monkeys were tested one at a time and had 12 disks to spend in each experiment. Jake always showed the monkeys on apple piece, while Allison always showed two pieces. But that's not necessarily what they gave the monkeys. The number of apple pieces given for a disk was determined at random.

    Experiment One: Allison showed two pieces of apples but gave both piece only half the time. The other half, she took one piece away and gave the monkey just the remaining piece. Jake, on the other hand, always gave exactly what he showed: one piece for each disk. The monkeys chose to trade more with Allison.

    Experiment Two: Allison continued to sometimes gave two pieces and sometimes one piece. But now, half the time, Jake gave the one apple piece he was showing, and half the time he added a bonus. Guess what? The monkeys chose to trade more with Jake.

    In the first experiment, the monkeys correctly figured out that if they traded with Allison, they'd end up with more treats. In the second one, when a monkey received two pieces from Jake, it seemed like a gain. When Allison gave the monkey only one piece instead of the two she showed, it seemed like a loss. The monkeys preferred trading with Jake because they'd rather take a chance of seeming to win than seeming to lose.

    We also sometimes make silly business decisions just to avoid the feeling that we're getting less, even when we're not. Would you have made the same choices?

    A new mom from Michigan headed for the airport Thursday, nervous about flying alone with her -month-old. When her daughter started crying even before take-off her fears for the flight — to surprise her husband, a US Army soldier at Fort Rucker Alabama — seemed acceptable.

    The couple seated next to her reacted just as Rebekka Garvison had feared, looking visibly unhappy about sitting next to a fussy(难以取悦的)baby. Ms. Garvison moved to a new seat, hoping it would help. When the baby's cries continued, the woman sitting next to her asked if she could try.

    Garvison later described in a grateful Facebook post how the woman, Nyfesha Miller, had the magic touch with her baby. "As soon as she had her, Rylee was looking out the window and stopped crying," Garvison recalled. "When we got in the air she fell right asleep and slept in her lap the whole flight until we got to our gate? Garvison told The Huffington Post she has been in touch with Ms. Miller almost daily since the flight.

    Garvison's post has been shared more than 84,000 times, and received hundreds of warm comments. "Years ago, the same kind of thing happened to me," wrote one mother. "It was a seven-hour flight and I had my ten-month-old little boy with me. A nun （修女）was sitting beside me and she walked him up and down the passage when he got fussy. It was such a relief for me and is something I will never forget."

    Not everyone has had happy experiences with baby air travelers. One airline is considering opening a "baby class" for airplanes with flight attendant nannies（保姆）, reported The Christian Science Monitor's Meredith Hamilton. For now, parents can hope to be seated beside someone like Ms. Miller on their next flight. "Nyfesha Miller, you will never understand how happy this act of kindness has made my family." wrote Garvison.

Scientists have long thought about whether each animal species has a different language, much like different human languages that we cannot understand. Language experts agree on the fact that the way animals communicate through various calls does not fit the definition of human languages.

Animal calls are not considered a language because the calls are limited to signals related to food activities, warning about the presence of enemies and so on. They lack the characteristic of productivity that all human languages share. That is — humans create new expressions every day by combining different words to express meanings. Animal calls are fixed in their meanings, while human language goes further and includes expressions of complex ideas that do not have a limit.

However, animals do communicate. People who study humans believe that people speak with their entire bodies. To express a message, one does not always need words. Have you ever shared a private joke with your friends across the table? All you did was to give them a self-satisfied smile, Animals can communicate in much the same way as humans do. Although animals do not have the ability to speak words, they can use other methods, such as gestures, movements, calls and their sense of smell. In short, most of their communication is not related with speech.

If animals can make noises, why can't they talk? Humans and animals both have the necessary organs that produce sounds, such as lungs, throat, voice box, lips and tongue. But the differences lie in the movement and relative position of these organs that make it possible for us to speak.

When humans developed from apes, a lot of our features were improved to better shape sounds along the way. The mouth started getting smaller and the neck grew longer. All other animals, including our closest animal relatives — chimpanzees, have little similarity, which determines humans' ability to speak.
