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."

    Human brains begin growing and developing at a very young age. They learn from the simplest experiences, which enable your children to be aware of the world. There's no denying that outdoor play helps a lot!

Times when children have to wait for their turns on playground equipment and following the playground rules by sharing, all these form components of a healthy social-emotional development. Young children develop their social-emotional skills through practice and small steps over time.

As parents or caregivers, it is fairly simple to support your child's social-emotional skills. Acts like holding him, touching him, and speaking to him and giving him loving care and attention are all helping factors. When you allow them freedom to play, it is important to follow their interests in helping build their social-emotional skills.

Difficulties in social-emotional skills can often lead to children having trouble when playing with other children. Becoming easily angry or not empathizing (理解) with other children are all signs that may point in this direction. This can in turn lead to them not empathizing with the needs of other children.

    As for the development of cognitive (认知的) skills, these develop through practice and opportunity over time. And while some cognitive skills may be genetic, most are learned through real life situations. In other words, learning and thinking skills can be improved through experiences.

    To enable them to learn, it is important that we are mindful of what our children are interested in. And this realization is only set in place once the child is given enough room and time to grow and explore.

    Depriving children of such experiences can mean that they might struggle with higher- level thinking skills. And while it is normal to keep them safe, we forget that by rushing them and cutting down on play time, we're actually causing more harm than good.

    The Miami Planetarium (天文馆|) opened its doors to the public on November 4, 1966 and has entertained and educated children of all ages about astronomy and the wonders of the night sky ever since. The Planetarium houses a 65-foot diameter domed (圆顶状的) projection screen with 231 seats. At the heart of the Planetarium is a SPITZ “Space Transit Planetarium” star projector (放映机)， which is capable of accurately reproducing the stars and planets as seen from anywhere on Earth at any time during the year. Shows daily except Thanksgiving and Christmas Day. Unlike any other in South Florida, the Planetarium is a unique setting for bringing the stars and planets indoors in animated (动画) live star shows and music-filled laser light shows.

    The Weintraub Observatory (天文台) houses two powerful telescopes. Observatory hours are from 8:00 p.m. to 10:00 p.m. Look though the telescope to view the planets, the four moons of Jupiter, the rings of Saturn and deep sky objects such as galaxies, nebulate and double stars.

    Deposit (定金): A $75 deposit must be received 10 days prior to the visit date to guarantee your visit.

    Cancellation Policy: The museum requires 48 hours advance notice prior to any cancellation or other changes to a reservation. Without prior notification (通告) the original total will be expected upon arrival.

    Payment Policy: The balance of the admission fee is due upon arrival at the museum on your visit day.

    Upon Arrival: The leading teacher should check in at the box office with payment for the correct head count of students, and teachers. Visitors should remain on the bus until a museum interpreters show you around the museum.

Museum Etiquette (规矩): We ask that all groups remain together and orderly. Teachers are asked to help maintain order with their groups. We reserve the right to refuse service to any group or individual not obeying the museum policies.

    Bus Procedures: The museum will provide parking for buses in our parking lot. Upon arrival, bus drivers will be directed by the museum staff to the appropriate places to park. It is recommended that buses remain on the spots throughout the group's entire museum visit.

    The bike-sharing companies that are powering a transportation revolution in China's urban centers are not like those in the rest of the world. Their bikes have no docking ports or assigned zones for parking. Instead, riders open their smartphone apps, hop on, and start riding. So easy!

    In 2015, Ofo, China's bike-share pioneer, launched its first fleet of bicycles in Beijing. The bikes' bright yellow frames were soon met by the orange-rimmed（镶边）, basket-equipped models launched by Mobike, Ofo's main competitor today. In little over a year, the two companies have had a huge impact on revitalizing (重振) cycling in China, particularly among young people.

    Ofo placed 1 million bicycles across 35 cities and registered 15 million users in its first years, while Mobike has now gained more than 10 million unique users and bicycles in 21 cities. Inspired by their success, at least 10 other companies have jumped into the market, launching their own app-powered, brightly colored bikes in quick succession. But Mobike and Ofo are far ahead of them.

    The two industry leaders each take a different marketing method to a similar product. The Mobike app uses GPS to display bikes' locations to users. They can use the map to reserve a bike and walk over to it. A scan of the bike's QR code (二维码) unlocks the bike, and when users manually（手动地） lock the bike at the end of their trip, the app records the trip's end and the bike will pop back up on the map as available. Equipped with this wireless technology, Mobikes cost between 1,000 and 3,000 yuan. Rides cost 1 yuan for an hour or a half hour, depending on whether a user chooses a “Lite” or regular bike, and the deposit (押金) required to the service is 299 yuan.

Ofo, meanwhile, is devoted not just to producing its own bikes, which have slim yellow bodies and cost about 250 yuan, but also to connecting existing bikes to its network—-- a philosophy that begins with the practice of 2000 bikes offered to a campus bike-share program. The 2000 bikes were the first generation of Ofo. Yet the majority of the company's bikes are currently ones that have been specially manufactured and fitted with their lock system. Unlike Mobike,Ofo bikes themselves are offline: their locations are tracked through users' cell phones. Users find a free bike, enter the license plate number into their app, and receive the bike unlock code. When they have reached their destination, they end the ride on the app and manually lock the bike. Rides cost 1 yuan for an hour and the deposit is 99 yuan.

    Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星) which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

    However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse.

    Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart.

    This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

    It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested.

    In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley's comet, in his honour.

    Gabriella's family immigrated to the US from Peru when she was two years old. As a compound bilingual (双语使用者), Gabriella develops two linguistic codes at the same time, with a set of concepts, learning both English and Spanish. Her teenage brother, on the other hand, might be a coordinate bilingual, working with two sets of concepts, learning English in school, Spanish at home. Finally, Gabriella's parents are likely to be subordinate bilinguals who learned a second language by translating it into their mother tongue.

    Regardless of accent and pronunciation, all types of bilingual people can become fully proficient in a language. It seems that the difference may not be apparent. But recently brain imaging technology has given a glimpse into how specific aspects of language learning affect the bilingual brain. It's well known that the brain's left hemisphere (半球) is in charge of logical processes, while the right hemisphere is more active in emotional and social ones. Language involves both types of functions. "Critical Period Theory" says children learn languages more easily because their developing brains let them use both hemispheres in language learning, while in most adults, language relies on one hemisphere, usually the left.

    Before the 1960s, bilingualism was considered a handicap that slowed the children's development by forcing them to spend too much energy distinguishing between languages. But a recent study did show that bilingualism may make you smarter. It does make your brain more complex, healthier, and more actively engaged, and even if you didn't have the good fortune of learning a second language like a child, it's never too late to do yourself a favor and make the linguistic leap from "Hello" to "Hola" "Bonjour" or "nihao" because when it comes to our brains, a little exercise can go a long way.
