Newborns begin to develop language skills long before they begin speaking. And, compared to adults, they develop these skills more quickly. People have a hard time learning new languages as they grow older, but babies have the ability to learn any language easily.

    For a long time, scientists have tried to explain how such young children can learn the complicated grammatical rules and sounds of a language. Now, researchers are getting a better idea of what's happening in the brains of the tiniest language learners. This new information might help kids with learning problems as well as adults who want to learn new languages. It might even help scientists who are trying to design computers that can communicate like people do.

    Most babies go “ma ma” by 6 months of age, and most children speak in full sentences by age 3. For many years, scientists have wondered how the brains of young children figure out how to communicate using language. With help from new technologies, scientists are now finding that babies begin life with the ability to learn any language. They get into contact with other people, listen to what they say and watch their movements very closely. That is why they quickly master the languages they hear most often.

    Studies show that, up to about 6 months of age, babies can recognize all the sounds that make up all the languages in the world. Starting at around 6 months old a baby's brain focuses on the most common sounds it hears. Then, children begin responding only to the sounds of the language they hear the most.

    In a similar way older babies start recognizing the patterns that make up the rules of their native language. For example, English children who are about 18 months old start to figure out that words ending in “-ing” or “-ed” are usually verbs, and that verbs are action words.

    Make new friends, but keep the old. One is silver, and the other gold.

    This song expresses a nice rule: increasing friends. Sometimes things actually work out that way. I've met adults who've said, “We've been friends since kindergarten!” A friend who has known you forever is a treasure. But friendships don't always last — especially for children.

    When I was growing up, my family moved about every three years. The advantage of this was that I got to see different parts of the world, and it made my family very close. I also learned to be pretty good at making new friends, and, to keep in touch with old friends, I became a great letter writer. But I always admired those kids who stayed in one place and kept their friends for a long time. I didn't learn that children's friendships can disappear even when no one moves until I was much older, with children of my own.

    Sometimes friendships end in quarrels and hurt feelings. But perhaps the most painful end to a friendship is the one-sided rejection — one friend turns away, or chooses someone else as a close friend, and the other child is left feeling sad and wondering why this thing happened. The end of a friendship is often sad, but it's not necessarily a bad thing. Often the end of one friendship makes more room for other friendships to grow.

    When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie,“ Homeless to Harvard: The Liz Murray Story”, shown in late April.

    Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

    Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “What drove me to live on had something to do with understanding, by understanding that there was a whole other way o f being. I had only experienced a small part of the society,” she wrote in her book Breaking Night.

    She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”. She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS.“I love my parents so much. They are drug addicts. But I never forget that they love me all the time.”

    Liz wants moviegoers (who often see films) to come away with the idea that changing your life is “as simple as making a decision”.

    The aggressive spread of market economics and communication technologies~often under the control of Western multinational companies—brings new challenges to local cultures and values in non-Western societies. Sometimes it seems as if a tidal wave of the worst Western culture is creeping across the globe like a giant strawberry milkshake spill oat and over the planet, with a flavor that is distinctly sweet, sickly and apparently homogeneous (同质的).

    For some, especially the young, change may mean escape from oppressive traditions. It may also bring new opportunities for cultures to be combined in creative ways. However, there is genuine cause for concern about the rate at which cultures are being worn away in such a globalized world.

    Perhaps by far the most important far-reaching effect of cultural globalization is the commercialization of culture, which has a disturbing impact on local people's existing values. They are increasingly bombarded with new images, new music, new clothes and new values. The familiar and old are to be abandoned. While there was cultural change long before globalization, there is a danger that much will be lost simply because it is not valued by global markets. In West Africa for example, traditional values have been overtaken by Coca-Cola culture which the local people don't yet have the values to deal with successfully.

    Another common aspect of the globalized culture is that it pursues (追求) the same “one size fits all" American ideal. The result of this cultural process of homogenization is that a large section of the world's population dreams of living like Cosby & Co. or like the characters in any other stereotype American soap opera. In addition, the dream of living a better life causes thousands of people to move to already overcrowded cities whose population has boomed by millions within the last decades. The majority of these new immigrants end up in slums leading to poverty, pollution and misery.

    Such gradual aggression against people's existing values and cultures has a destructive impact on their sense of who they are, what they want and what they respect. It attacks spiritual values and faith traditions. The accumulative (累积的)effect in non-Western societies is a crisis of cultural confidence, combined with the increased economic uncertainty and crime which global integration (一体化)may bring. This creates real problems for social stability» whether it is at the level of nation, community or family.

    In conclusion, cultural globalization，or worldwide McDonaldization, destroys diversity and displaces the opportunity to sustain decent life through a mixture of many different cultures. It is more a consequence of power concentration in the global media and manufacturing companies than the people's own wish to abandon their cultural identity and diversity,

Do you believe that things are connected for no scientific reason at all? For example, do you avoid saying the word "four" to avoid bad luck? If so, you have a superstition (迷信). And you're not alone — all kinds of people have them.

For example, Portugal's soccer superstar Cristiano Ronaldo always steps onto the pitch (球场) with his right foot first, according to The Telegraph. And sports players are not alone in having superstitions. A visitor once asked the Nobel Prize winning scientist Niels Bohr whether he really believed that the horseshoe he'd hung at his country home was lucky. "Of course not," the Danish physicist said. "But I understand it's lucky whether you believe in it or not."

One recent study found that even scientists at MIT and other top US schools tended to look for a meaning in natural events, similar to the connection between stepping on the pitch and playing soccer well, according to The Atlantic. When the researchers gave the scientists little time to answer questions, they were twice as likely to agree with statements such as "Trees produce oxygen so that animals can breathe" as they were when they had more time to think about their reply.

It seems that fear can make people think differently in this way, too. In a British study, students imagined meeting a "witch" who said she would cast (施魔法) an evil spell(符咒) on them. About half said a scientist should not be worried about the spell. Yet each of them said that, personally, they wouldn't let the witch do it to them.

So why are so many of us superstitious? Well, it seems to be our way of dealing with the unknown. "Many people quite simply just want to believe," Brian Cronk, a professor of psychology at Missouri Western State University, said in a 2008 interview. "The human brain is always trying to work out why things happen, and when the reason is not clear, we tend to make up some pretty bizarre (古怪的) explanations."

    And these explanations aren't completely unhelpful. In fact, superstitions can sometimes work and bring real luck, according to psychologists at the University of Cologne in Germany in the May 2010 issue of the journal Psychological Science. They found that believing in something can improve performance on a task like an exam.

    So, what about you? What superstitions do you follow to keep you safe and successful?

    In my life, my grandfather has influenced me a lot. Ever since I was a little kid, I have always loved sports, especially football. My grandfather also enjoys sports and really loves football. He received a couple of awards in football matches. Through my three years so far in high school, my grandfather has helped me become a better player.

    Another reason why I admire my grandfather so much is because of his strong work ethic(道德). Ever since I was a little boy, my grandfather has taught me and shown me what good work ethic means. He is a good example. When he was a young man, his family owned a small store. He often helped his father run the store. He has also done several jobs in his life. He owned his own store when my mother was a young girl; he helped on a farm; he then had his own painting business. Now he is working at a Wal-Mart.

    Responsibility(责任) is something that I have struggled with in the past. My grandfather, on the other hand, is a very responsible person. That's why I am very responsible now, because of him. When he was in school, he was almost a straight A student. I, on the other hand, don't do so well. One day he had a talk with me about being more responsible. He helped me in school and made me realize how important grades are. Now I get almost As and Bs.

    Now you can see why I admire and respect my grandfather as much as I do. He is the best role model I have, and I will always look up to him.
