    Make-A-Wish Foundation

    Sometimes all it takes is one wish made come true to make someone smile. The work of Make-A-Wish Foundation is to make the wishes come true. Through support and donations, the foundation has made dreams come true for hundreds of thousands of children with serious illnesses.

    If you want to help others, don't wait for a better time. Help now! Your help will be valued highly.

    It is difficult for parents of nearly every family to teach their children to be responsible for housework, but with one of the following suggestions, you really can get your children to help at home.

    If you give your children the impression that they can never do anything quite right, then they will regard themselves as unfit or unable persons. Unless children believe they can succeed, they will never become totally independent.

    My daughter Carla's fifth-grade teacher made every child in her class feel special. When students received less than a prefect test score, she would point out what they had mastered and declared firmly they could learn what they had missed.

     You can use the same technique when you evaluate (评价) your child's work at home.

    Don't always scold and give lots of praise instead. Talk about what he has done right, not about what he hasn't done. If your child completes a difficult task, promise him a Sunday trip or a ball game with Dad.

    Learning is a process of trying and failing and trying and succeeding. If you teach your children not to fear a mistake of failure, they will learn faster and achieve success at last.

    London—A morning's train ride away, across the Channel, English kids talk about Liverpool's soccer team in a Paris pub. Some Parisians have even started to go to work in London. In the 19^th century, Charles Dickens compared the two great rival (竞争) cities, London and Paris, in " A Tale of Two Cities". These days, it might be A Tale of One City.

    Parisians are these days likely to smile in sympathy at a visitor's broken French and respond in polite English. As jobs grew lack at home over recent years, perhaps 250,000 Frenchmen moved across the Channel. With an undersea tunnel, they could travel between cities in three hours. The European Union freed them from immigration and customs.

    Paris, rich in beauty, is more attractive. But London feels more full of life, and more fun until the pubs shut down.

    "For me, the difference is that London is real, alive," said Trevor Wheeler, a banker.

    Chantal Jaouen, a professional designer, agrees. "I am French, but I'll stay in London," she said.

    There is, of course, the other view. Julie Lenoux is a student who moved to London two years ago. "I think people laugh more in Paris," she said.

    In fact, London and Paris, with their obvious new similarities, are beyond the old descriptions. As the European Union gradually loosened controls, Londoners flocked into Paris to shop, eat and buy property (地产).

    "Both cities have changed beyond recognition." Said Larry Collins, a writer and sometimes a Londoner. Like most people who know both well, he finds the two now fit together comfortably.

    "I first fell in love with Paris in the 1950s and it is still a wonderful place," Collins said. "But if I had to choose, it would be London. Things are so much more ordered, and life is better."

    But certainly not cheaper. In fancy parts of London, rents can be twice those on Avenue Foch in Paris. Deciding between London and Paris requires a lifestyle choice.

    Like Daphne Benoit, a French journalism student with perfect English, many young people are happy to be close enough so they don't have to choose.

    "I love Paris, my little neighborhood, the way I can walk around a centre, but life is so structured," she said. "In London, you can be who you want. No one cares."

    One afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of the wonderful works.

    A young couple viewing the paintings ahead of me chatted nonstop between themselves. I watched them a moment and decided she was doing all the talking. I admired his patience for tolerating her constant words. Disturbed by their noise, I moved on.

    I encountered them several times as I moved through the various rooms of art. Each time I heard her constant talking, I moved away quickly.

    I was standing at the counter of the museum gift store doing some shopping when the couple approached the exit. Before they left, the man reached into his pocket and pulled out a white object. He turned it into a long cane (手杖) and then tapped his way into the coatroom to get his wife's jacket.

    "He's a brave man," the clerk at the counter said, "Most of us would give up if we were blinded at such a young age. During his recovery, he made a promise that his life wouldn't change. So, as before, he and his wife come in whenever there's a new art show."

    "But what does he get out of the art?" I asked, "He can't see."

    "Can't see! You're wrong. He sees a lot. More than you or I do," the clerk said, "His wife describes each painting so he can see it in his head."

    I learned something about patience, courage and love that day. I saw the patience of a young wife describing paintings to a person without sight and the courage of a husband who would not allow blindness to change his life.

    And I saw the love shared by two people as I watched this couple walk away arm in arm.

    My First Marathon

    Three weeks before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only one week to train. Yet, I was determined to go ahead.

    I remember back to my 7th year in school. In my first P.E. class, the teacher required us to run laps and then hit a softball. My performance was really terrible. He later informed me that I was "not athletic".

    The idea that I was "not athletic" stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!

    The night before my marathon, I dreamt that I couldn't even find the finish line. I woke up sweating and nervous, but I was ready to prove something to myself.

Shortly after crossing the start line, my shoe laces became untied. So I stopped to readjust. Not the start I wanted!

    At mile 3, I passed a sign: "GO FOR IT, RUNNERS!"

    By mile 17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.

    By mile 21, I was starving!

    As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a.m. or questioned my expenses on running.

    I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.

Determined to be myself and move forward, free of shame and worldly labels(世俗标签), I can now call myself a "marathon winner".

    Many leading AI researchers think that in a matter of decades, artificial intelligence will be able to do not merely some of our jobs, but all of our jobs, forever transforming life on Earth.

    The reason why many regard this as science fiction is that we've traditionally thought of intelligence as something mysterious that can only exist in biological organisms, especially humans. But such an idea is unscientific.

    From my point of view as a physicist and AI researcher, intelligence is simply a certain kind of information-processing performed by elementary particles (基本粒子) moving around, and there is no law of physics that says one can't build machines more intelligent than us in all ways. This suggests that we've only seen the tip of the intelligence iceberg and that there is an amazing potential to unlock the full intelligence that is potential in nature and use it to help humanity.

    If we get it right, the upside is huge. Since everything we love about civilization is the product of intelligence, amplifying (扩大) our own intelligence with AI has the potential to solve tomorrow's toughest problems. For example, why risk our loved ones dying in traffic accidents that self-driving cars could prevent or dying of cancers that AI might help us find cures for? Why not increase productivity through automation (自动化) and use AI to accelerate our research and development of affordable sustainable (可持续的) energy?

    I'm optimistic that we can develop rapidly with advanced AI as long as we win the race between the growing power of our technology and the knowledge with which we manage it. But this requires giving up our outdated concept of learning form mistakes. That helped us win the race with less powerful technology: We messed up with fire and then invented fire extinguishers (灭火器), and we messed up with cars and then invented seat belts. However, it's an awful idea for more powerful technologies, such as nuclear weapons or superintelligent AI—where even a single mistake is unacceptable and we need to get things right the first time.
