Most damagingly, anger weakens a person's ability to think clearly and keep control over his behaviour. The angry person loses objectivity in evaluating the emotional significance of the person or situation that arouses his anger.

    Not everyone experiences anger in the same way; what angers one person may amuse another. The specific expression of anger also differs from person to person based on biological and cultural forces. In contemporary culture, physical expressions of anger are generally considered too socially harmful to be tolerated. We no longer regard duels(决斗) as an appropriate expression of anger resulting from one person's awareness of insulting behaviour on the part of another.

    Anger can be identified in the brain, where the electrical activity changes. Under most conditions EEG(脑电图) measures of electrical activity show balanced activity between the right and left prefrontal(额叶前部) areas. Behaviourally this corresponds to the general even­handed disposition(意向) that most of us possess most of the time. But when we are angry the EEG of the right and left prefrontal areas aren't balanced and, as a result of this, we're likely to react. And our behavioural response to anger is different from our response to other emotions, whether positive or negative.

    Most positive emotions are associated with approach behaviour: we move closer to people we like. Most negative emotions, in contrast, are associated with avoidance behaviour: we move away from people and things that we dislike or that make us anxious. But anger is an exception to this pattern. The angrier we are, the more likely we are to move towards the object of our anger. This corresponds to what psychologists refer to as offensiveanger: the angry person moves closer in order to influence and control the person or situation causing his anger. This approach­and­confront behaviour is accompanied by a leftward prefrontal asymmetry(不对称) of EEG activity. Interestingly, this asymmetry lessens if the angry person can experience empathy(同感) towards the individual who is bringing forth the angry response. In defensiveanger, in contrast, the EEG asymmetry is directed to the right and the angry person feels helpless in the face of the anger­inspiring situation.

    One of the most recent social changes taking place in the world is social networking. Social networking has been in existence for at least 150 years, and probably longer than that. In the times before the invention of the computer and the World Wide Web (WWW), social networking was done in person. People who had similar likes and interests would gather together to share experiences, make new friends, and improve their businesses.

    On the Internet, social networking websites made their first appearances during the late 1990s. The first major social networking website in the United States was MySpace. MySpace allowed its users to exchange messages, share pictures, and make new friends in a way that was never thought of in the past. With MySpace, people who did not go out much could reach out to others from their own homes.

    In 2004, Facebook was created. It was first a website created for use by Harvard University's students and teachers, but it soon expanded to include just about everyone. It is now larger than some of the largest companies in the world. It is a website that is changing all the time. Facebook has completely changed the way people stay connected with each other and the rest of the world. The way it works is simple. Users can set up a new account (账户) easily. All a new user needs is an email address to start. Once a person has created an account and his friend also has his own Facebook page, he can invite his friend by sending a request out to him. Once you get started, making new friends will come easily.

    Many Years ago three soldiers,hungry and tired of battle,came upon a small village.The villagers,suffering a bad harvest and the many years of war,quickly hid what little they had to eat and met the three in the village square, shaking their heads and sighing,"Well,we are starving."The soldiers communicated with each other quietly and then the first soldier turned to the villagers.“Your poor fields have left you nothing to share,so we will share what little we have: the secret of making soup from stones.”

    Naturally the villagers were intrigued and soon a fire was built to the village's greatest pot,and then the soldiers dropped in three smooth stones.

“Now this will be a fine soup,”said the second soldier,"but a handful of salt and some parsley（香芹）would make it wonderful!"Up jumped a villager,crying “What a piece of luck!I've just remembered where some has been left!”

    And off she ran,returning with parsley.As the pot was boiling,the memory of the villagers improved: soon carrots,beef and cream had found their way into the great pot.They ate and danced and sang well into the night, thrilled about the feast and their new-found friends.In the morning the three soldiers awoke,finding all the villagers standing before them.At their feet lay a bag of the village's best bread and cheese.“You have given us the greatest gift,”said an elder,“and we shall never forget.”The third soldier turned to the crowd,and said,“There is no secret,but this is certain: people working together can accomplish great things.”At last the light dawned on villagers.Off the soldiers wandered,down the road.

    One of the United States' social problems is the breakdown of the two-parent family. Today, millions of American children grow up without fathers. Too often, these children lack the love and help they badly need and which they would ordinarily receive from not one but two parents. In the old days, American parents placed the needs of their children above their own. At present, however, nearly one half of all new marriages end in divorce(离婚), with often troubling results for their children. Worse, every year, thousands of teenage, unmarried Americans become mothers outside marriage. However, Chinese continue to value whole marriages. This is not to say that Chinese marriages are all perfect - they certainly are not, there are increasing more divorces in China - but the willingness of Chinese to set aside their own needs and stay together for the sake of the children is highly respected and worthy of study.

    Families are important to Americans. If one was to ask a group of Americans what is the dearest to them, the majority would say “family”. And yet, so many Americans spend much more time at work- that is, beyond the formal forty-hour work week - than they do with their own families. It seems to me that Chinese generally find a better balance between work and family needs than many Americans do. Average Chinese usually head home right after work，have meals together, and spend time with their family members. What's more, Chinese try to make more time for grandparents, uncles, aunts and cousins than many Americans; in many cases, multigenerational families live together. Of course, like many facts of Chinese society, this is all changing; increasing numbers of “New Chinese” are working longer hours and spending less time with their families than ever before. Still, while Americans do value their loved ones, I think we have something to learn from the Chinese about finding the proper balance between work and family.

    Have you ever thought of quitting your job when you feel exhausted? Maybe most of you would say "yes". After a particularly busy period at work, I decided to get away from it all by going on a hike in the mountains in southern France.

    Before I left, I read an interesting story in a magazine. It read, "Once, while I was riding on a crowded bus, the man sitting next to me threw his cell phone out of the window when his phone rang. I was surprised. He looked at me, shrugged (耸耸肩) and looked away. I had no idea whether it was his or stolen or whether he even knew what a cell phone was or not, but he clearly wanted to be free of it, because it clearly troubled him."

    Billions of people across the world use cell phones. Though cell phones are a wonderful way for communication, they often do the exact opposite. Using cell phones can increase stress within families and friends.

    So when I recently returned home, I got rid of my cell phone. Now I go outside without taking my phone with me. I've noticed things in my neighborhood I never noticed before, such as gardens. I've met new people, started conversations with neighbors I didn't speak to before and talked with some of my friends face to face instead of chatting over the phone.

    Instead of keeping me off from the world, stopping using my cell phone has helped me get even closer to my family and friends.

    Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics, but sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you build a positive sell-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative serf-image is to realize that your image is far objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting positive self-image. When you can pat(拍)yourself on the back, you'll know you're well on your way. Good luck!
