Claude Sammut,a professor of computer science and engineering at the University of New South Wales in Australia,said it would soon be possible for robots to defeat the stars of the future.

    For many years,Mr Sammut has been a member of a project called RoboCup,where robots have been programmed to learn how to play football and compete against others in a football match.

    As he explains,the robots are having difficulty in learning how to control the ball and move the ball on their own,but he is still full of confidence that one day in the future they will show the same skills as Wayne Rooney,who is one of the best football players in the world.

    Mr.Sammut also said,"In 1968,John McCarthy and Donald Michie made a bet with David Levy,who was then the chess champion in Scotland,that within 10 years a computer program would be able to beat him.It took a little bit longer than 10 years (nearly 30 years) but eventually such programs came into being."

    "In the same spirit of a grand challenge,RoboCup aims to develop a team of robots that can defeat the world soccer champion team by the year 2050.To achieve this,or come even closer to the ambition,the robots will have to be able to sense and act in completely unstructured environments.This will require major advances in perception（感知）,decision making,learning,and cooperative behaviors.Considering robots are integrated hardware and software systems,great advances will also be needed in sensors（传感器）,energy storage,and materials."

    Bedtime on the Orient Express. We stood in the corridor while a woman pulled our bunk beds (双层铺) into place-- there wasn't room in the carriage for all three of us. Barking the news that she would be waking us at 7 a.m. with a cup of instant coffee and a piece of cheese, the woman left and we retired for the night.

    'Bunk beds?' you may be thinking. Small carriage? Instant coffee? This can't be the real Orient Express! Oh, but it is. This is a very real Orient Express indeed. In search of a long weekend in Vienna, there seemed no more attractive way for my friend and me to get there.

    The original Orient Express service was started in 1863. Luxury carriages ran the route from Paris, France to Giugiu, Romania. In 1934, Agatha Christie sent Hercule Poirot on just such a journey in her novel Murder on the Orient Express. However, there was a rise in air travel which was quicker and cheaper and eventually the whole operation was brought to a halt in 1977. The name was reused in 1982, when the Venice Simplon-Orient-Expresss took its first voyage between London and Venice.

    Admittedly I would have loved to take the Venice Simplon-Orient-Express, with its on-board shop and piano in the bar, but at around £1,700 per person for a four-night one-way journey, it was too expensive for us. So we chose this excellent way of buying into the romance for a small amount of the cost.

    But we loved it. Ours was no luxury bedroom, but it had its own rough charm-- not to mention the magic of travelling across international borders overnight. I haven't slept in a bunk bed since I was seven, and climbing up into it took 25 years off me. For one night only, it was comfortably appealing. Naturally, I took a copy of Murder on the Orient Express to read on the train. I smiled at the descriptions of airy dining cars and fresh coffee.

    My weekend in Vienna was wonderful and reunited with the cut-price Orient Express at the end of the holiday, we were rather delighted to see our little carriage again. Good old bunk beds. Terrifying old attendant. And best of all, nobody got murdered.

    Fred Rogers was a curious man, six feet tall and without pretense (虚伪). He liked to pray, to play the piano, to swim, and to write, and he somehow lived in a different world than I did. We became friends for some 20 years, and I made lifelong friends with his wife, Joanne. I remember thinking that it seemed as if Fred had access to another realm (领域) like the way pigeons have some special magnetic compass that helps them find home.

    Fred died in 2003, somewhat quickly, of stomach cancer. He was 74. "Just don't make Fred into a saint (圣人)," That has become Joanne's refrain (叠句). 91 now, still full of energy, she lives alone in the same roomy apartment, in the university section of Pittsburgh, that she and Fred moved into after they raised their two boys. Throughout her 50-year marriage to Fred, she wasn't the type to hang out on the set or attend production meetings. That was Fred's thing. He had his career, and she had hers as a concert pianist. For decades she toured the country with her college classmate, Jeannine Morrison, as a piano duo; they didn't retire the performance until 2008.

    "If you make him out to be a saint, people might not know how hard he worked," Joanne said. Disciplined, focused; a perfectionist — an artist. That was the Fred she and the cast and crew knew. "I think people think of Fred as a child-development expert," David Newell, the actor who played Mr. "Speedy Delivery" McFeely, told me recently. "As a moral example maybe. But as an artist? I don't think they think of that." that was the Fred I came to know. Creating, the creative impulse (冲动), and the creative process were our common interests. He wrote or co-wrote all the scripts for the program — all 33 years of it. He wrote the melodies. He wrote the lyrics. He structured a week of programming around a single theme, many of them difficult topics, like war, divorce, or death.

    I don't know that he cared whether people saw him as an artist. He seemed more intent (急切的) that people not see him at all. The focus was always on you. Or children. Or the tiny things. It was hard to see Fred.

    I like you just the way you are. One day he told me where that core message came from. His grandfather, Fred Brooks McFeely, who like the rest of the Rogers family lived in Latrobe, Pennsylvania, about 40 miles east of Pittsburgh. "He was a character," he said. "Oh, a lot of me came from him."

    His grandfather represented a life of risk and adventure, the very things Fred's boyhood lacked. He was a lonely kid, an only child until he was 11, when his sister came. He was bullied. Here comes Fat Freddie! He was sickly. He had asthma. He was not allowed to play outside by himself. He spent much of his childhood in his bedroom.

    He had music, and he had puppets to keep himself amused. He didn't need much. He was expected to fill his father's shoes, become his business partner at the brick company. "My dad was pretty much Mr. Latrobe," he told me. "He worked hard to accomplish all that he did, and I've always felt that that was way beyond me. And yet I'm so grateful that he didn't push me to do the kinds of things that he did or to become a miniature (缩小的) version of him. It certainly would have been miniature."

    Fred wanted to be like his grandfather. "He taught me all kinds of really neat stuff!" he told me. "I remember one day my grandmother and my mother were telling me to get down, or not to climb, and my grandfather said: ‘Let the kid climb on the wall! He's got to learn to do things for himself!' I heard that. I will never forget that. What a support that was. He had a lot of stone walls on his place." "I think it was when I was leaving one time to go home after our time together," Fred told me, "that my grandfather said to me: ‘You know, you made this day a really special day. Just by being yourself. There's only one person in the world like you. And I happen to like you just the way you are."

A children's choir (合唱团) from the snowy highlands of Tibet recently1 their beautiful singing to the capital, Beijing.
