Driving could soon be a far more pleasant experience thanks to a personal in-car robot being developed by researchers. The robot, which is called “Affective Intelligent Driving Agent (AIDA)” will be able to tell you the best route home based on traffic reports, remind you to pick up petrol and suggest places you may like to visit. The robot, which sits on the dashboard, is being developed at the Massachusetts Institute of Technology (MIT) in collaboration with Volkswagen.

    AIDA communicates with the driver through an expressive robot screen and will even appear sympathetic if you're having a bad day. Cynthia Breazeal, director of MIT's Personal Robots Group, said: “We are developing AIDA to read the driver's mood from facial expression and other cues and respond in a proper way.”

    AIDA works by analyzing the driver's mobility patterns, keeping track of common routes and destinations. The creators say the robot should be able to work out home and work locations within a week of driving. Soon afterwards, the system will direct the driver to their preferred supermarket, suggesting a route that avoids traffic-clogged roads. AIDA might recommend a petrol stop en route if the fuel tank is nearly empty. The robot will also incorporate real-time information about traffic jams, the weather report, commercial activity, tourist attractions, and residential areas.

    “In developing AIDA we asked ourselves how we could design a system that would offer the same kind of guidance as an informed and friendly companion.”

    “AIDA can also give you feedback on your driving, helping you achieve more energy efficiency and safer behavior,” Assaf Biderman from SENSEable City Lab added.

    Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their cooperation and support, passing around necessary nutrition “depending on who needs it”.

    Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
     Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest
   “We didn't take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    People from Britain and Ireland first came to live in Australia in 1788. They brought different dialects （方言）of English with them. These different kinds of English began to mix and change. The newcomers soon began to speak with their own typical accent（口音） and vocabulary. More and more people came to Australia during the Gold Rush in the 19th and 20th centuries. Some came from Britain and Ireland; others came from non-English speaking countries. Australian English continued to grow and change.

    Australian English has also been influenced by American English. During the Second World War, there were many American soldiers staying in Australia. More importantly, American television shows and music have been popular in Australia since the 1950s.

    Australians use many words that other English speakers do not use. The famous Australian greeting, for example, is G'day! A native forest is called the bush and central Australia is called the outback. Many words were brought to Australia from Britain and Ireland. For example, mate means "friend", and it is still used in Britain. Some of these words have changed in meaning. Some words have come from Australian original languages, many of which are names for animals, plants and places, like dingo and kangaroo.

    Australian spelling comes from British spelling. In words like organise and realise, -ise is the expected and taught spelling method. In words like colour, favourite, -our is the normal, but nouns such as the Labor Party and Victor Harbor are spelled with -or. Program, on the other hand, is more common than programme.

    There are also differences in the definition （定义）of words Australians use in different parts of the country. For example, football means "rugby" in New South Wales and Queensland, but "Australian rules football" in everywhere else in Australia. In New South Wales, a swimming costume is called a cossie or swimmers, while in Queensland it is called togs and bathers in Victoria.

    It's school time again! You're probably feeling excited and maybe a little sad for the vacation is over. Some kids feel nervous on the first day of school because of all the new things: new teachers, new friends, and maybe even a new school. Luckily, these "new" worries only stick around for a little while. Let's find out more about going back to school.

    Most teachers kick off the school year by introducing themselves and talking about what you'll be doing that year. Some teachers give students a chance to tell something about themselves to the rest of the class.

    When teachers do the talking on the first day, they often go over classroom rules so you'll know what's allowed and what's not. Pay close attention so you'll know if you need to raise your hand to ask a question and what the rules are about visiting the restroom.

    You might already know a lot of people in your class on the first day. But it's a great day to make new friends, so try to say "hello" to the kids you know and new ones that you don't. Make the first move and you'll be glad about what you did and so will your new friends!

    Most teachers let you pick your own seat on the first day, but by the second or third morning, they'll have mapped out a seating plan. It's a good idea to write down where your seat is in your notebook so you don't forget.

    Here are a few final tips for a fantastic(奇异的) first day: Get enough sleep. Have a healthy breakfast. Try your best. Develop good work habits, like writing down your assignments(作业) and handing in your homework on time. Take your time with schoolwork. If you don't understand something, ask the teacher.

    You may think there are no differences between British and American people. After all, they speak the same language, don't they? If you ask a British or an American person, he will probably tell you that there are differences. And the differences are quite great.

    What do British people think American people are like? The British think American people are very strange. They make a lot of noise and they laugh too loudly. They are rich, and they only think about money. But the British do say that American people are kind, and friendly people. They're happy to help you if you are in trouble.

    What do Americans think of the British? Well, they think the British are cold and very unfriendly. They are not interested in success or in making lots of money. They think British is the best country in the world. They look down on other countries. But Americans say that the British are quite hard workers. They are brave and honest. And in time of trouble they face difficulties happily.

    You can see that these ideas can cause misunderstanding between the British and Americans. But when American and British people become friends, they usually find things are not as bad as they expected.

    Have you ever wondered how your favorite NBA team received its famous name? All NBA teams have an interesting story or a history behind their names. Some of the names reflect the city's culture or history, others came from previous owners and many were selected through "Name the Team" contests.

    For teams like Los Angeles and Utah, the names were not always a reflection of the city. Even though Los Angeles has no lakes, the Laker name has been a city treasure for almost 40 years. Before going to Los Angeles, the team originated in Minneapolis, Minnesota. In 1948, team officials chose the name for its direct relationship to the state's motto, "The Land of 10,000 Lakes." The team name went unchanged after moving to Los Angeles in 1960.

    Because Utah's team originated in New Orleans, Louisiana, it was called the Jazz. In 1974, New Orleans club officials chose the name to represent the city for its reputation as the "jazz capital of the world." The name stayed with the team even after finding a new home in Salt Lake City, Utah in 1979.

The Chicago Bull's original owner, Richard Klein, named the team the Bulls. He picked the name because a fighting bull is relentless, and never quits. Klein, who founded the club in1966, believed these qualities were necessary for a championship team and hoped his Chicago athletes would live up to the team name. A belief that Bulls—winner of the six NBA championships have definitely followed.

    In 1967, the Indian Pacers selected their team name in a different way from most other teams. Their decision was based on what they wanted to accomplish in the NBA. Team officials chose the Pacers name because the organization wanted to set the "pace" in professional basketball.
