Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?

    In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.

    Passionate love is rooted in the reward circuitry of the brain—the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner.

    What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman's reproductive health.)

    Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.

    One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.

    What happened to that brilliant idea that you once had? Did you ignore it because you thought that it was just a little thought? Have you ever considered what that little thought would have become if you had acted on your instincts(本能) or if you had paid more attention to it?

    Imagine a scene, where you are sitting at home watching television or reading a book, suddenly a light bulb is turned on in the dark tunnel of your mind as a thought or an idea crosses your mind. The thought catches your attention but seems so meaningless and you are tempted to abandon it, but wait a minute!

    That thought could be the potential beginning of the success you have so much wished for. As the thought crosses your mind, your senses become alert and you suddenly see a possibility, a solution, or find the answer to a problem whose solution has long escaped you.

    It is almost as if a wise man has whispered the perfect solution into your ear or awakened your senses to a reality, thereby bringing light to your life. It is like finding the last piece of jigsaw puzzle(拼图游戏). This becomes an amazing moment and everything freezes around you as you excitedly try to grasp the practicality of that little but powerful thought.

    Your self-confidence and enthusiasm increase as you become conscious of the great possibilities that can arise if that little thought is acted upon. This becomes the moment to build upon that thought and to put down any ideas that are streaming from that little thought for later review.

    Seemingly meaningless little thoughts or ideas when acted upon have a potential to explode into great projects.

    Many successful projects have been born from the little positive thoughts that were carefully protected and recognized as tickets to great things.

You may have heard people say many times that it just came to me in a flash moment, a small idea or seemingly meaningless thought may cross your mind about something you have been planning to accomplish.

    Don't waste an opportunity to act on a potentially brilliant idea. You don't have to wait for a major idea, or approval from your peers in order for you to act on that little thought. That little thought or idea is the beginning of great things if you decide to follow it through.

    By now, we are all aware that social media has had a powerful influence on our culture, in business, on the world at large. Social media websites revolutionized the way people communicate and socialize on the Web. However, besides seeing your friends' new baby on Facebook, or reading about Justin Bieber's latest conflict with the law on Twitter, what are some of the real influences?

    Social networks offer the opportunity for people to reconnect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and take part in campaigns and activities of their choice. Professionals use social media sites like Linkedln to improve their career and business development. Students can work together with their peers to improve their academic and communication skills.

    Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying(网络欺凌) and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.

    Many companies have blocked social networks as addicted employees can distract (分心)themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.

    Also, what you carelessly post on the Net can come back to trouble you. Leaking personal information on social sites can make users easily harmed to crimes like identity theft, stalking(尾随犯罪), etc. Many companies perform a background check on the Web before hiring an employee.  If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.

    Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to improve their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.

    Hip-hop culture covers many fields; it includes spoken words, break-dancing, beat-making, painting, fashion, lively design, technology, and more. Hip-hop is becoming the unofficial music in the education world, as more artists launch school programs, summer camps, and other activities connected city youth in the classroom through the beliefs of hip-hop culture. Even more and more university teachers — who once would have been strongly against hip-hop — have joined the crew. In the past two decades, hip-hop culture, including hip-hop education, has become a legitimate(合法的) field of study in universities and the subject of numerous books.

    Hip-hop culture has influenced every piece of American and global culture because the culture is so prevalent. Teachers must be willing to engage in it if it's part of the unique reality of their students' lives. That way, teachers can truly be effective, reaching students in a meaningful, culturally connected way.

    Teachers might at first feel frightened by hip-hop culture, an area in which they might not have previous knowledge or experience. But a lack of knowledge is actually a blessing; the best trained hip-hop educators have been those that are at the beginning disconnected(分离的) from the culture. One of the biggest sayings in hip-hop is “keep it real”. If a teacher comes to the classroom and says, “I don't know hip-hop, but I recognize that it's your culture and I want to learn,” the kids will teach the teacher, and then the students will be more willing to learn from that educator. Hip-hop is about a respect for youth culture.

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.

Children who were behind in their development at age 4-5 were almost three times as likely to have been out of education,employment,or training at age 16-17,analysis of pupil data has found. 

4-5-ycar-olds in England are assessed by the Early Years Foundation Stage Profile,and those who reach the boundary of a"good level of development"are considered"school ready". 

The new study in the journal BMC Public Health has found a significant gap in Not in Education,Employment or Training (NEET)outcomes between those who were ready and unready for primary school. The research drew on data from more than 8,000 Bradford young people whose records are linked as part of the Connected Bradford project. The research found that 11%of children who were not school ready went on to be NEET at 16-17, compared to just 4%of children who were school ready. 

Lead author Dr Matthew Warburton,Research Officer at Leeds' School of Psychology, said:"These findings tell us that there are clear,early indicators for children and young people being at risk of disadvantage in late adolescence. As schools routinely collect this data,the research could be used to kickstart early intervention in schools based on primary school readiness. "

The research team,which also included academics from Lancaster University and the Bradford Institute for Health Research,say this shows a clear need for early intervention by schools to reduce disadvantage in later life. 

This echoes the message from a series of N8 Child of the North and Centre for Young Lives reports on the need to put children and young people first. Senior author Dr Amy Atkinson,Lecturer in the Department of Psychology at Lancaster University said:"Data from the Early Years Foundation Stage Profile is readily available for millions of children and young people in England. This information could,and should,be used to identify pupils at increased risk of becoming NEET. "
