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.

The Basics of Math—Made Clear

    Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of arithmetic and to prepare them for Algebra(代数) and beyond.

    The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents(指数), the order of operations, and square roots. In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.

    Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students. The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and overcome their anxiety about this amazing—and completely understandable—field of study.

    By the conclusion of the course, students will have improved their understanding of basic math. They will be able to clear away the mystery(神秘性) of mathematics and face their studies with more confidence than they ever imagined. In addition, they will strengthen their ability to accept new and exciting mathematical challenges.

    Professor H. Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious. From the basic concrete ideas to the more abstract problems, he is master in making math lectures learner-friendlier and less scary.

    With a PhD in Mathematics Education from Georgia State University, Dr. Siegel teaches mathematics at Central Arizona College. His courses include various make-up classes and a number of lectures for future primary school teachers.

    If the course fails to provide complete satisfaction to you, you can easily exchange it for any other course that we offer. Or you can get your money back.

    My elder cousin Ted liked complaining almost about everything. When he faced a problem, he always chose to complain about it instead of finding a way to solve it. That was not right. Ted was healthy and had received a good education. He should and could find a good job and work hard to feed himself, but he just complained all day, drifting from one job to another. One day, I read about a farmer called Chris and told Ted about the farmer.

    Chris works hard, performs many jobs around the farm. But Chris is not exactly like other farmers. What makes him different is that he was born without arms or legs. But this has not stopped him from working hard and getting things done.

    Now, you may ask, is this possible? Like many other amazing people who have no arms or legs, Chris does not focus on what he can't do, but rather on what he can do. And he can do a lot! He drives farm vehicles and looks after crops. Once you see Chris in action, you will think there is nothing he could not do.

    Chris is a great example of a person who is making the most of his gifts. His positive attitude and courage make him a true inspiration.

    After I told Ted about Chris, he became silent. Compared with Chris, Ted was much luckier. Then luckily, I saw Ted's change.

    Do you like complaining? If you do, think about Chris. Such a man chooses to stay positive. Why don't we?

    Few of us haven't read Cinderella, the story of a young woman living in poverty who meets the prince of her dreams. Some might not want to admit it, but there is a hidden Cinderella in everyone's heart—we all wish we could achieve recognition or success after a period of obscurity or neglect.

    Mary Santiago has that secret dream, too. Her story is featured in Another Cinderella Story, a film set in a US high school.

    Mary is shy but loves to dance. Compared with other girls, she is invisible. However, her world changes completely when a famous teenager pop singer, Joey Parker, appears.

    Joey is everything that the rest of the boys in her class are not — kind, handsome and desirable. Mary and Joey's paths cross at a ball. They meet and fall in love with each other. But when Mary has to rush back home, she leaves behind her MP3 player, which becomes the only clue Joey has to find the girl of his dreams. Of course, there is a wicked(邪恶的) stepmother, who turns out to be Dominique Blatt and she takes in Mary after her dancer mother dies. Dominique treats Mary like a maid and does everything she can to make sure Mary doesn't get into the top dance school. Her two daughters are equally determined to stop Joey falling for Mary, even if that means embarrassing her.

    The story, though it mostly follows Cinderella, does add a few modern day twists to the classic fairy tale. Refreshingly, the film, unlike many high school films, does not focus on looks, although the actors are all beautiful. There is also a lot less materialism in Another Cinderella Story than in many similar movies.

    “The movie takes the Cinderella fairytale as its jumping off point,” writes the movie critic Amber Wilkinson. “The focus is firmly on following your dream.”

    You probably know you should say” please” and “thank you ” at restaurants. You probably know the rules of a library. You know you should respect and be nice to your classmates. But do you have music manners?

    Keep It Down! You have to notice the volume of your music. You should not play your music so loud that everyone around you can hear it. Some people might even get angry. Usually, when you play the music loud on an MP3 player, other people can't hear the words of the song. They just hear a loud sound. Not one wants to listen to this. Very loud music can also be bad for your ears, so even if you are alone when listening to our MP3 player, you shouldn't have it turned up too high.

    Take Them Off! You need to know when to turn your MP3 player off and put it away. Libraries and schools don't allow MP3 players. There are other places, like museums, that don't have rules, but it would be rude to have your MP3 player on. Sometimes, it just doesn't make sense（没意义） to listen your MP3 player at event. Why would you listen to music at a play, a movie or a sporting event? You would miss what is going on and others would wonder why you even came.

    Take One Out! Once in a while it's okay just to take out one earphone and not the other. Imagine you are listening to your MP3 player when someone asks you the way. It would not be rude to take out one earphone, tell him the way, and put back the earphone and continue listening. You can also do this when you order food at a fast-food restaurant.

    It's Your Choice! There are times when you need to decide what is best. For example, some people can listen to music on their MP3 Players when read books, while others think it is disturbing. In cases like this, you need to do what seems right for you.

    English is the most widely used language in the history of our planet. One in every seven human beings can speak it. More than half of the world's books and three quarters of international mail are in English. Of all languages, English has the largest vocabulary — perhaps as many as two million words.

    However, let's face it: English is a crazy language. There is no egg in an eggplant, neither pine nor apple in a pineapple and no ham in a hamburger. Sweet-meats are candy, while sweetbreads, which aren't sweet, are meat.

    We take English for granted. But when we explore its paradoxes (探讨它的矛盾), we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them.

    And why is it that a writer writes, but fingers don't fing, grocers don't groce, and hammers don't ham? If the plural of tooth is teeth, shouldn't the plural of booth be beeth? One goose, two geese — so one moose, two meese?

    How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell the next?

    English was invented by people, not computers, and it reflects (反映) the creativity of human beings. That's why, when stars are out, they are visible (能看见的); but when the lights are out, they are invisible. And why, when I wind up my watch, I start it; but when I wind up this essay, I end it.
