While most of us are happy to take the credit when things go well, few of us are willing to take the blame when things go wrong. Rather than trying to hide our shame or embarrassment, experts found that we are simply less aware when our actions result in a negative outcome.

       The research may explain why we often feel it hard to take the blame for our actions. “Our result suggests that people may really experience less responsibility for negative than for positive outcomes，” said Patrick Haggard, leading researcher and professor of the institute of Cognitive Neuroscience at University College London.

      In a series of tests, participants were asked to press a key. A sound then followed, either disapproving, neutral or approving, and they were then asked to estimate the time between the action and when they had heard the sound.

      Researchers found that individuals experienced different levels of responsibility depending on the outcomes. They also discovered they were significantly slower to recognize if their actions had resulted in a bad consequence, compared to when they had done well.

   “Effectively, we have found that we experience a negative outcome differently, not just retell it differently. We make a weaker connection when there is a bad result. And respond much more strongly when something good happens，” said Professor Haggard. When something goes right, everyone wants to take the credit, and when things go wrong, nobody is interested in putting their hands up.

        The researchers say our brain is “very much concerned” with reward, as good results are key to survival. Although our own perception (认知) of whether we are guilty of something or not is changed by the outcomes, this does not provide a defense if we have done something wrong. “Our experience of our own responsibilities can be misleading and can be strongly colored by the outcomes of our actions，” said Professor Haggard. “We have to take responsibility for what we actually do, not just for how we experience things.”

    New friends. Fresh lifestyle. Better career opportunities…Those are attractions of overseas study for young people in China. “Start early, finish strong,” some of them say.

    Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.

    In the early 16^th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

    Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18^th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

    Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

    You may probably meet most of the powerful graduation speakers, here who are well-known people in their fields. I think the schools couldn't have picked better speakers than them, because they set good examples, deeply inspiring us in our daily life.

    1）Steve Jobs, Stanford University:

   "Remembering you're going to die, and the best way I know is to avoid the trap of thinking that you have something to lose. There is no reason not to follow your heart. Your tine is limited, so don't waste it living someone else's life. Don't let the noise of others' opinions drown out your own inner voice. …"

    2）Oprah Winfrey, Stanford University：

   "I consider the world, this Earth, to be like a school. And the secret I've learned to get ahead is being open to the lessons from the grandest universe of all. Don't react against a bad situation. And the solution will arise from the challenge. So don't give up easily, acting with responsibility. …"

    3）Bono, University of Pennsylvania：

   "For four years you've been buying, trading, and selling everything you've got in his market-place of ideas. Your pockets are full, even if your parent's are empty, and now you've got to figure out what to spend it on…The world is more flexible than you think and it's waiting for you to hammer it into shape…"

    4）Michael Del, University of Texas at Austin;

   "Now it's time for you to move on to what's next and obtain your desire. But you much must not let anything prevent you from taking those first steps. Don't spend so much time trying to choose the perfect opportunity, or sometimes you'll miss the right opportunity. Recognize that there will be failures obstacles. But you will learn from your mistakes and the mistakes of others."

    Jon Pedley is making a big change. He is giving up his life as a successful businessman for life of helping others. He is trading his beautiful farmhouse in England for life in a mud hut it Uganda, East Africa.

    Pedley admits that he has not always led a very positive life. At times he drank too much and got in trouble with the law. "I've always put the pursuit(追求) of money in front of everything else. As long as I was all right, I didn't care who I was hurting," says Pedley.

    But a visit to Uganda in 2007 gave Pedley a new outlook(观点) on life. He was amazed at what he saw and how much the people there appreciated the work he was doing. "I worked there for a few days and these people who have nothing thanked me by giving me bags of potatoes, which are a fortune for them," he said.

    Now Pedley is selling his business, his $1.5 million farmhouse, and his expensive car — and moving into a hut made of mud and boards in a small Ugandan village. There he will help run an organization that hopes to improve the quality of life for people in the village of Kigazi. He will help to build schoolrooms for children and tanks to hold clean water for villagers. Today, people in Kigazi must walk two miles to a hospital, so Pedley will help to build doctors' offices, too.

    Pedley's organization will also work with English teenagers who are in trouble. The teens will be sent to a "camp" in Uganda that Pedley will run. The teens will live in mud huts and help to build water, health and education facilities(设备) for kids in Kigazi, many of whom have lost their parents due to poverty or disease. Pedley hopes the teens will see a side of life that might help them turn around their own lives and set them on a new and more positive path.

    I've always felt a need to be prepared for whatever situation I've found myself in.

    My mother once took me to a store when I was seven years old. She and I got to the checkout counter, and she realized she had forgotten a couple of things on her shopping list. She left me with the cart and ran off to get what she needed.

    "I'll be right back." she said.

    She was gone just a few minutes, but at that time, I had loaded all the things on the belt and everything was rung up. I was left staring at the cashier, who was staring at me. "Do you have money for me, son?" she said. "I'll need to be paid."

    I didn't realize she was just trying to please herself. So I stood there, ashamed and embarrassed.

    By the time my mom returned, I was angry. "You left me here with no money! This lady asked me for the money, and I had nothing to give her."

    Now that I'm an adult, you'll never catch me with less than $200 in my wallet. I want to be prepared in case I need it.

    I've always admired people who are over-prepared. In college, I had a classmate named Norman. One day he was giving a speech on an overhead projector(投影仪) and in the middle of his talk, the light bulb（灯泡）on the projector blew out. We would have to wait ten minutes until someone found a new projector.

    "It's Okay." he said. "There's nothing to worry about."

    We watched him walk over to his bag and pull something out. He had brought along a spare(备用) bulb for the overhead projector. Who could even think of that?

    I often told my students, "When you go into the wilderness, the only thing you can depend on is what you take with you." And essentially, the wilderness is anywhere but your home or office. So take money. Pack a light bulb. Be prepared.
