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."

    Silence is unnatural to man.He begins life with a cry and ends it in stillness.In between he does all he can to make a noise in the world,and he fears silence more than anything else.Even his conversation is an attempt to prevent a fearful silence.If he is introduced to another person,and a number of pauses occur in the conversation,he regards himself as a failure,a worthless person,and is full of envy of the emptiest-headed chatterbox（喋喋不休的人）. He knows that ninety nine percent of human conversation means no more than the buzzing of a fly,but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure（蜡塑人像）.

    The aim of conversation is not,for the most part,to communicate ideas;it is to keep up the buzzing sound.There are,it must be admitted,different qualities of buzz;there is even a buzz that is as annoying as the continuous noise made by a mosquito.But at a dinner party one would rather be a mosquito than a quiet person.Most buzzing, fortunately,is pleasant to the ear,and some of it is pleasant even to the mind.He would be a foolish man if he waited until he had a wise thought to take part in the buzzing with his neighbors.

    Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk.Very few human beings join in a conversation in the hope of learning anything new.Some of them are content if they are merely allowed to go on making a noise into other people's ears,though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel.At the end of an evening,during which they have said nothing meaningful for a long time.They just prove themselves to be successful conservationists.

    "How are you" is a nice question. It's a friendly way that people in the United States greet each other. But "How are you?" is also a very unusual question. It's a question that often doesn't have an answer. The person who asks "How are you?" hopes to hear the answer "Fine.", even if the person's friend isn't fine. The reason is that "How are you?" isn't really a question and "Fine." isn't really an answer. They are simply other way of saying "Hello!" or "Hi!".

    Sometimes, people also don't say exactly what they mean. For example, when someone asks, "Do you agree?", the other person might be thinking, "No, I disagree. I think you're wrong…"But it isn't very polite to disagree strongly, so the other person might say "I'm not sure…". It's a nice way to say that you don't agree with someone.

    People also don't say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person says "I've to go now." Often, the person who wants to hang up gives an excuse," Someone is at the door." "Something is burning on the stove." The excuses might be real, or it might not. Perhaps the person who wants to hang up simply doesn't want to talk any more, but it isn't polite to say that. The excuse is more polite, and it doesn't hurt the other person.

    When they are greeting each other, talking about an idea, or finishing a talk, people often don't say exactly what they are thinking. It's an important way that people try to be nice to each other, and it's also a part of the game of language.

    Does your local high school have a student newspaper? Only 1 in 8 of New York's public high schools has student newspapers – and many of those are published just a few times a year. A few more are online, which can leave out poorer schools.

    Rebecca Dwarka, an 18-year-old senior who works for her student paper said, “Facebook is the new way of finding out what happened. Nobody wants to actually sit down and read a whole article about it. This makes a 'whole article' sound a little like a long sentence in lonely places.”

    I am not nostalgic(怀旧的) about high school student newspapers and never worked for mine. I put out what was then called a personal magazine with a group of friends because we wanted to write about peace, war and rock 'n' roll without school officials warning us not to make jokes about the local officials.

    School newspapers are in decline(衰落) because students now find out what happened on social networking websites. This is a little discouraging because it proves that for millions of Americans, journalism is becoming a do-it-yourself thing. Every citizen can be a reporter.

    When something happens, we look for social media messages. Facebook posts and Tweets have become the means by which citizens and reporters can prove, deny, pass on stories and express opinions without the press' challenging, researching or slowing the message.

    But truly good journalism is a craft, not just a blog post. It requires seeing something carefully and it uses an eye for details to help prove a larger view. And even journalism that conveys an opinion tries to be fair. If school newspapers begin to disappear, I hope there are other ways for students to learn that.

    Oct.15th was International White Cane Safety Day. You may have never heard of it, but it was a day to remember for Peng Baier, 17, of Nanjing Foreign Language School. After school that day, he visited his local Disabled Persons' Federation (残疾人联合会). He wanted to know about the sales and feedback (反馈) of his newly published book, How to Help a Disabled Person.

    Since he lives with his disabled grandparents, he understands that life can be hard for this group of people. Peng decided to write the book because he wanted to create a better life for disabled people in China.

    “Crossing the street is a big problem for them,” Peng said. “Speeding cars, people walking in a hurry, bikes on the sidewalk for the blind - accidents can happen everywhere. That's why we hardly ever see disabled people on the street, even though there are millions of disabled people in China.”

    Peng's book with pictures is easy to understand. It is a guide to the right and wrong ways to treat disabled people. The left-hand pages show the reader the right way; the right-hand pages point out mistakes that are commonly made.

    The teenager had 2,000 copies of his book printed. With the help of the Disabled Persons' Federation, he gave them to the disabled community.

    “The book is bilingual, so foreigners can also use it,” said Peng.

    Peng put great effort into the book. For example, he interviewed many disabled people to get first hand materials. He also studied textbooks from different schools for the disabled. Peng finally completed his handbook, but he still had the problem of getting it printed.

    How does a high school student raise money needed for that?

    With a smile, Peng said how he went about it. “I visited three local companies, dressed up in a suit and tie. I was lucky. The companies were warm-hearted and willing to give me a hand.”

    If you wear glasses, chances are you are smarter. Research published in the famous British journal Nawre Conurunications has found — people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.

    The scientist, studied the genes of thousands of people between the ages of 16 and 102. The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were intelligent, there was a higher chance they need glasses. Scientists also said being smarter has other benefits. It is connected to better health.

    It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connoted to something else does not mean one of those caused the other. And it's worth noting that what constitutes (构成)intelligence is subjective and can be difficult, if not impossible, to measure.

    Forget genes thought. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do no, need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers this idea to help win their cases. Lawyer Harvey Slovis explained this. "Classes soften their appearance," he said. Sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren't found guilty.

    Glasses are also used to show someone is intelligent in movies and people who wear glares have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, thought. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip(时髦的). However, that hasn't stopped many celebrities (名人) from happily wearing glasses even if they do not need them. Justen Bieber is just one high - profile fen of fashion glasses.
