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."

    The Price of Success

    One problem for schools is that many students do not want to study hard. As a result, they perform (表现) poorly in their classes. This is especially true in the United States, where average scores for math and science are lower than in many other countries. In recent years, schools and charities have been looking for ways to help students get better grades in these subjects. An organization called the LMD Foundation introduced a program called Learn and Earn recently.

    In the program, money was used to get a group of students to study harder in math and science. In addition to the normal school day, they went to after-school classes for four hours each week. The students were paid eight dollars for each hour of after-school class. By the end of the year, the students in the program had higher grades than a similar group of students who had not taken part.

    Not everyone thinks that this is a good idea, though. TV reporter John Tulenko studied data (数据) from a similar program. He found that students' grades went back down when they stopped getting paid. Many people are worried about this. They think that the students study because they want money, not because they enjoy learning. Also, some people believe that these types of programs are a bad idea because it is a large part of a teacher's job to get students to study. If students are given money, some teachers might stop trying to do this.

    However, others believe that these learning programs can be helpful for students from poor families. Many of these students do part-time jobs after school, and some even quit school at a young age to work. Some do this to help get money for their families. Others feel that they can learn more by working than by going to school. Programs like Learn and Earn let these students stay in school and still make money.

    Actually, long-distance bicycle camping is one of the most pleasurable activities I have ever experienced.

    I generally sleep poorly at night, but in the woods on a tour, I sleep like a baby, falling asleep with the music of insects. In the morning, I am awakened by the cheeps of birds. I eat a snack before getting up, and then I quickly pack my sleeping bag, air mattress (垫), tent, and other things and get on with my road. I'm slower in the morning, having less speed but a greater desire to stop at pleasant spots and enjoy the beautiful scenery. Traveling by bike allows me to stop anywhere, such as grasslands, lakes, woods, and scenic spots. Near lunch, I find a small grocery and buy some bread, sandwiches and fruit. Then I will find a town park or other shady spots to wait out the high mid-day sun. In the afternoon, my speeds are higher, and I spend less time on stops. In the late afternoon, I start riding more slowly, and I start thinking about where I will stop. I finally find a place in the early evening, cook a simple meal and have a rest. As it starts to get dark, I put up my tent, crawl in and fall asleep.

    There are exciting times and difficult times as well. Visiting strange or famous places and accomplishing goals are always exciting to me. I meet and talk with interesting people along the way, sometimes other traveling cyclists. Appreciating beautiful views, meeting wild animals, and traveling up and down hills also. On the other hand, I may run into a rainy or hot spell(一段时间), have to repair my bike, or just find myself in a bad mood. The problems are infrequent and are easy to deal with. The pleasures remain in my mind for years.

    Have you ever learned about F. Scott Fitzgerald? F. Scott Fitzgerald, born on September 24, 1896, an American novelist, was once a student of St. Paul Academy, the Newman School and attended Princeton. University for a short while. In 1917 he joined the army and was posted in Alabama, where he met his future wife Zelda Sayre. Then he had to make some money to impress her.

    His life with her was full of great happiness, as he wrote in his diary:" My own happiness in the past often approached such joy that I could share it even with the person dearest to me but had to walk it away in quiet streets and take down parts of it in my diary."

    This side of paradise, his first novel, was published in 1920. Encouraged by its success, Fitzgerald began to devote more time to his writing. Then he continued with the novel the Beautiful and Damned (1922), a collection of short stories Thales of the Jazz Age (1922), and a play The Vegetable (1923). But his greatest success was The Great Gatsby, published in 1925, which quick brought him praise from the literary world. Yet it failed to give him the needed financial security. Then, in 1926, he published another collection of short stories All the Sad Young Men.

    However, Fitzgerald's problems with his wife Zelda affected his writing. During the 1920s he tried to reorder his life, but failed. By 1930, his wife had her first breakdown and went to a Swiss clinic. During this period he completed novels Tender Is the Night in 1934 and The Love of the Last Tycoon in 1940 while his wife was in hospital in the United States, he got totally addicted to alcohol. Sheila Graham, his dear friend, helped him fight his alcoholism.

    Whether in the home or the workplace, social robots are going to become more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like partners than tools. For example, these robots will be able to tell when someone is happy or sad. This allows them to respond more properly to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just give general answers to questions; it responds based on what it learns about each person in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential(潜在的) applications in everything from education to health care and are already finding their way into some of these areas.

    Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not aimed to replace workers, but to work together with other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.
