Kunta wondered why the white people had done this to him. Born a free man, he was now in chains. Heavy iron chains around his feet and hands were fixed to a metal bar that ran round the hall about ten centimeters off the ground. He was just able to lie down on the ground, but could not stand up.

    Kunta had been seized in the forest and then hit on the head with a hard object. When he woke up, his hands and feet had already been tied together. What shocked him most was that the men who carried him were black. He reasoned with them, and tried to persuade them to set him free. But they would not listen to him. When they came to the river, a white man was waiting in the boat for them. There was an argument about money, so it seemed, in a language that Kunta did not understand. Finally, Kunta was thrown into the bottom of the boat and covered with an old smelly cloth. The men took him in their boat to the castle on the coast where he was now held prisoner.

    Another thing which shocked Kunta was that women were held in the castle too. He could hear their crying, also children's voices. What was to become of them all, he wondered. For all his life, he had known that people suddenly disappeared from their villages. He had known that it was not safe to travel alone in the forest near the coast. But why did white people want to catch Africans and put them in chains? Would they be killed or even eaten? The situation seemed hopeless and he knew his life was in danger.

    Worse was to come. A few days later about 140 black people were taken and put on a tall sailing ship waiting off the coast. Once on the boat, they were taken below and their chains were fixed to two bars that ran the length of the ship. Their feet were fixed to one bar and their hands to another bar. Thus they lay on hard wooden boards, unable to stand up or move around.

    The sea journey lasted over sixty days and nights. They had rough weather and Kunta's back bled from rolling over on the hard wooden boards. Many of the men fell sick with fever. They sighed and cried out for more water, but food and water were only given out once a day. Once in a while sailors came down, Kunta thought, to carry sick men upstairs for treatment. When the ship finally arrived in a port, the wooden cover was opened wide and Kunta could see in daylight for the first time across the part of the ship where he had been chained. About a third of the people who had been chained up below at the beginning of the journey were missing.

    Two friends have an argument that bleaks up their friendship forever, even though neither one can remember how the whole thing got started. Such sad events happen over and over in high schools across the country. In fact, according to an official report on youth violence, "In our country today, the greatest threat to the lives of children and adolescents is not disease or starvation or abandonment, but the terrible reality of violence". Given that this is the case, why aren't students taught to manage conflict the way they are taught to solve math problems, drive cars, or stay physically fit?

    First of all, students need to realize that conflict is unavoidable. A report on violence among middle school and high school students indicates that most violent incidents between students begin with a relatively minor insult (侮辱). For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn't in the sandwich, but in the way students deal with the conflict.

Once students recognize that conflict is unavoidable, they can practice the golden rule of conflict resolution—stay calm. Once the student feels calmer, he or she should choose words that will calm the other person down as well. Rude words, name-calling, and accusation only add fuel to the emotional fire. On the other hand, soft words spoken at a normal sound level can put out the fire before it explodes out of control.

    After both sides have calmed down, they can use another key strategy for conflict resolution: listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterward, the listener can ask non-threatening questions to clarify the speaker's position. Then the two people should change roles.

    Finally, students need consider what they are hearing. This doesn't mean trying to figure out what's wrong with the other person. It means understanding what the real issue is and what both sides are trying to accomplish. For example, a shouting match over a peanut butter sandwich might happen because one person thinks the other person is unwilling to try new things. Students need to ask themselves questions such as these: How did this start? What do I really want? What am I afraid off? As the issue becomes clearer, the conflict often simply becomes smaller. Even if it doesn't, careful thought helps both sides figure out a mutual solution.

    There will always be conflict in schools, but that doesn't mean there needs to be violence. After students in Atlanta started a conflict resolution program, according to Educators for Social Responsibility, "64 percent of the teachers reported less physical violence in the classroom; 75 percent of the teachers reported an increase in student cooperation; and 92 percent of the students felt better about themselves". Learning to resolve conflicts can help students deal with friends, teachers, parents, bosses, and coworkers. In that way, conflict resolution is a basic life skill that should be taught in schools across the country.

    Researchers continue to show the power behind our sense of smell. Recent studies have found, among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers on roads.

    The review explains that smell is unique in its effects on the brain. According to Conrad King, the researcher who carried out the review, "more than any other senses, the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings. This is why the smell of baking bread can destroy the best intentions of a dieter."

    Smell, which dictates(决定) the unbelievable complexity of food tastes, has always been the least understood of our senses. Our noses are able to detect up to 10,000 distinct smells. Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000 genes (基因), which make up an amazing 3% of the human genome. Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004 for their ground-breaking research on the nature of this extraordinary sense. These two scientists were the first to describe the family of 1,000 olfactory (嗅觉) genes and to explain how our olfactory system works.

    According to one study in the research review, smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users. They are then more likely to speed and experience uncontrollable anger on roads. The most reasonable explanation is that these can all make drivers feel hungry, and therefore desperate to satisfy their appetites.

    In contrast, the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers' impatience. Similarly, the smells of lemon and coffee appeared to promote clear thinking and mental focus.

    However, the way genes regulate smell differs from person to person. A study by researchers in Israel has identified at least 50 olfactory genes which are switched on in some people and not in others. They believe this may explain why some of us love some smells and tastes while others hate them. The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors.

    The impression you make at the beginning of an interview is very important. Employers often decide to hire someone in the first three minutes of the interview. They judge you by your appearance, attitude and manners.

    A friendly smile when you walk into the room is important. A smile shows a confident and positive attitude.

    When you introduce yourself, make eye contact with the interviewer. Some interviewers offer a handshake. Others don't.

    Try to be as natural as possible. But pay attention to your body language. The way you sit, walk, gesture, use your voice and show feelings on your face is all part of your body language. It makes the interviewer know how you feel about yourself and the situation you are in. Are you feeling positively about yourself? Your abilities? Your interest in the job?

    Speak clearly and loudly enough. Show interest and enthusiasm in your voice. When you speak, look at the interviewer. Also, don't say negative things about yourself, or former employer.

    Listen to questions carefully. If you don't understand a question, ask the interviewer to repeat or explain:

    "I'm sorry, but I didn't catch that."

    "I'm not sure exactly what you mean."

    Almost everyone is nervous in a job interview. Interviewers know that. They don't expect you to be totally calm and relaxed. But they expect you to try to control your nervousness. They expect you to show confidence in your ability to do the job.

    At the end of the interview, thank the interviewer for her or his time.

    It's a good idea to send a short thank-you letter right after the interview, or deliver it by hand.

    Phone the company if you have not heard anything after one week. Ask if they have made a decision about the job.

    Good luck!

    Claude Monet, Pablo Picasso and Leonardo da Vinci ... the art world has never lacked talent. And now, a new painter is ready to join the list although this one isn't even human.

    Next month, auction house Christie's Prints and Multiples will make history by offering the first piece of art created by artificial intelligence (AI) for sale. The painting is a portrait of a man called Edmond De Bela- my, and is expected to be sold for up to $10,000.

    The work, which features a man with a mysterious look on his face, was created by software developed by the French art group Obvious. Laugero-Lasserre, an art collector, called the work "grotesque and amazing at the same time". This isn't the first example of Al-produced artwork, as AI has already been used to write poems and compose .songs. However, many people doubt whether it should be called art at all.

According to Russian writer Leo Tolstroy (1828 -1910), art is about creating emotion (情感). It's "a means of …joining people together in the same feelings' he once said.

So, if the emotion behind art is what makes it, the ability to create and use tools is what makes human Icings different from other species. And as a tool itself, the AI technology used to create the portrait is the result of a lot of effort made by several designers. Together, they "fed" the AI a huge collection of paintings from the 14th to the 18th centuries, until it was able to work out how to make similar paintings of its own.

    The introduction of AI art could be the beginning of a new artistic movement. However, not everyone is ready to welcome these high-tech artists just yet.

    "The human mind is what's behind the AI technology. And the human mind is not a cold, hard fact," said Oscar Schwartz, a professor of AI. "Rather, it in something that's created with our opinions and something that changes over

Would you drink water that had once been flushed down a toilet? After it's been cleaned, that is. The climate is warming, and the population of drought-prone states California continues to grow. So recycling wastewater into drinking water may become a necessity.

But, it can be really hard for people to get over their disgust at the thought of drinking recycled water. People are grossed out by cycled water, because it was once wastewater—you know, the stuff that goes down your kitchen drains, your showers, your toilets. And even though it's cleaned up to a standard that is identical, if not better, than commercially bottled water, the key barrier to recycled water acceptance is people's disgust regarding it, " said Daniel Harmon, a psychologist in University of California.

In one experiment, the researchers had some participants watch a short video promoting water conservation. And in another experiment, they added a video explaining why recycled water might trigger disgust even though all pollutants have been removed. And neither video had a strong effect on people's willingness to drink recycled water or to support the practice.

The messages were not enough to get them to actually use recycled water more. "Disgust is such a powerful reaction that simply giving more information is not going to really be effective. " The study appears in the journal Basic and Applied Social Psychology.

Researchers say it's probably going to take a lot more to get people to embrace recycled water. For example, it might help to see members of their community drinking water that's gone, as it's called, from "toilet to tap, " with no ill effects.

It is clear that these kinds of more direct campaigns for acceptance are necessary to get people to get over that psychological barrier—to take that first sip, so to speak. Cheers!
