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."

    Heading off to college this year? Here are some fashion tips from our experts you should keep in mind：

    Dress to impress: Stylist and business consultant Daniela Smith says, "Girls should keep in mind that your college professors will often be the bridge that connects you to your future career and your classmates will become your professional network. You don't need to dress like you're going to the office, but you should display an ability to properly present yourself with appropriate maturity and confidence, and look put­together."

    Logo mania (品牌狂热症): Wearing the logos of brands aimed at younger customers physically identifies you as part of that age group  so consider the targeted age group of the stores you shop at. It's tempting to load up on logos, especially well­known logos that signify high­end brands. But consider this: college is a time of self­discovery, a chance to develop your own personal style. Instead of wearing logos head to toe, "walking advertisement" style, why not express who you really are?

    Wear real pants: The combination of leggings and baggy shirts is all too common on college campuses. Smith points out that leggings, yoga pants, and sweatpants are entirely unacceptable in public unless you're exercising. Although leggings worn as pants are a common trend among high school and college girls, they are not an appropriate choice for daywear. As a young woman, your style choice should begin to reflect your maturity level. So, get rid of leggings and wear real pants!

    Keep the cute factor to a minimum: Stay away from sweaters and T-shirts with smiling animals, cartoon characters, or Hello Kitty on them. Sure, kittens might be cute, but they're not doing you any favors in the style department. Dressing too cutesy (矫揉造作的) can take years off your look, and not necessarily in a good way!

    Finding your feet in a new town can be hard, especially if you're covered in fur and don't speak the language. But for pets new to Marlborough, help is at hand.

    Marlborough SPCA and the Railway Café, in Blenheim, have joined forces to help welcome pets and their people to the area with morning teas. They hope the morning teas will get tails and tongues wagging(狗摇摆尾巴）as well as giving advice on how to make the move easier.

    Railway Café owner Leanne Harris came up with the creative plan as a way to help welcome people to the area. Leanne moved to Marlborough from Auckland two years ago and said she first struggled to find friends and feel part of the community. "Coming from Auckland I thought people would open their doors and that there would be neighbors calling round with cake. I expected people to come to me and, of course, it wasn't like that. I did get lonely." "I hope to save newcomers having to wait as long as I did to feel part of it all. I would like to welcome them to the town."

    Free plates of sandwiches, cakes will be offered, for the people, while there will be special yoghurt and banana treats for the dogs. The morning teas will take place in the covered area at the back of the popular café beside the railway station off Grove Rd.

    Leanne said she was happy to devote both her time and effort to giving back to the community and felt the project was a great fit with the SPCA.

    "Volunteering is such an amazing thing to do and it changed things for me completely, and I met some amazing people with similar interests."

    SPCA Op Shop manager Karina Greenall, originally from the United Kingdom, said she also wanted to help. "I can give advice on how to resettle pets, the best parks to go to, where the best walks are and where the Civil Service are in town." There will be volunteering chances too for people where they can help out and hopefully make friends too.

Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bags.

Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台). The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

Among the bag makers' argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.

The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

Environmentalists don't dispute (质疑) these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

On account of the government shutdown, many of the city's best attractions, such as the national museums, are closed. It may affect your social plans. That's especially true if you have out-of-town visitors coming to the District. Don't worry! For every closed museum, we've offered up a suitable substitute that is privately run, thus not subject to the shutdown. Here's where you can go instead.

Anacostia Community Museum and the National Museum of African American History and Culture

Alternatives: Banneker-Douglass Museum or Alexandria Black History Museum

The National Museum of African American History and Culture is one of the hottest draws on the National Mall, with free tickets taken weeks in advance. Its sister museum, the Anacostia Community (社区) Museum, takes a community-focused look at African American history. So does the Banneker- Douglass Museum in Annapolis, which traces (追溯) the African American experience in Maryland, and the Alexandria Black History Museum, where exhibitions honor local activists and explore the influence of slavery in the area. And unlike the African American Museum, neither requires you to plan ahead.

Hirschhorn Museum and Sculpture Garden

Alternative: Glenstone

Wandering through the galleries at Glenstone, you'll come across some of the biggest names in 20th century art — Jackson Pollock, Jean-Michel Basquiat and Robert Rauschenberg. Glenstone sits on a 230-acre estate (土地) that doubles as an outdoor sculpture garden. Free tickets for Glenstone are often reserved weeks in advance, but 72 free tickets are available every day for anyone who takes a Montgomery County Ride-On Bus from Rockville Metro Station to the museum.

National Museum of African Art

Alternative: The African Art Museum of Maryland

Masks, musical instruments and jewelry can be found in Fulton, where the African Art Museum of Maryland houses a collection of traditional and contemporary African artworks and objects. And the best part, for visitors on a budget? Admission is free.
