Walk down the drinks section at the supermarket.Look in the drink cooler in your local convenience store.A new drink is taking up more and more space on the shelves，and that drink is water.Bottled water sales in the US rose to 1.7 billion gallons in 2010 for plastic bottles alone，compared to total sales of only 700 million gallons in 1990. Whereas bottled water was once associated only with the rich and the privileged (特权阶层)，it is now regularly drunk by people at all income levels despite the fact that the price of bottled water can be between 240 and 10,000 times higher per gallon than tap water.What accounts for this surprising increase in demand?

    Traditionally，people have drunk bottled water for health reasons.The practice of “taking the waters” originated with the Romans，who believed that a person developed a healthy mind by building a healthy body.Across Europe，drinking or bathing in mineral water has been associated with the power to cure various diseases.Health spas at Evian in France and Pellegrino in Italy began bottling water so that their consumers could continue their treatments at home.The consumers in the 21st century are also concerned about health.However，in America，where the habit of drinking bottled water is relatively new，the concern is often more related to the purity or sterilization (消毒) of the water than to its mineral contents.Americans are often worried about the effects of the chemical pollution and other contaminants on the water supply.Many Americans view bottled water as a safe alternative to tap water.

    Further reasons for drinking bottled water are its usefulness as an aid to digestion，as a complement to a good meal in a restaurant，and for taste.City tap water is often treated with chlorine (氯) to guard against harmful micro­organisms.Chlorine，as well as metals from pipes and tanks used to distribute and store tap water，can leave behind an unpleasant taste.

    Australia is a big country, but it is easy to get around. The untouched beaches that go for miles and deserts that touch the horizon(地平线) are just there, waiting to be reached and explored. You can explore the big country in different ways.

Air

    Flying is the best way to cover large distances in a short time. You can spend more time on the Australia's landscapes(陆地风光) and relaxing lifestyle. Moreover, competition among airlines makes great flying fees available for you.

Drive

    Australia has a big network of well-kept roads and some of the most beautiful touring routes in the world. You have no trouble finding car rental companies at major airports, central city and suburbs(怒火).

Bus

    Bus travel in Australia is comfortable, easy and cheap. Buses generally have air conditioning, reading lights, adjustable(可凋) seats and videos. Services are good for everyone, frequent.

Rail

    Train travel is the cheapest and gives you an insight into Australia's size, all from the comfort of your carriage. Scheduled services are a great way to get quickly between our cities and regional centers.

Ferry(轮渡)

    The Spirit of Tasmania runs a passenger and vehicle ferry service between Melbourne and Tasmania nightly. Extra services are running during summer rush hours. Sea-link ferries connect South Australia and Kangaroo Island several times a day. Ferries connect suburbs in our capital cities.

    Besides all of above, you can also experience some of the longest tracks and trails in the world in central Australia-impressive journeys of a thousand kilometers or more that can take several weeks to complete.

    Life can be so wonderful, full of adventure and joy. It can also be full of challenges, setbacks and heartbreaks. Whatever our circumstances, we generally still have dreams, hopes and desires—that little something more we want for ourselves and our loved ones. Yet knowing we can have more can also create a problem, because when we go to change the way we do things, up come the old patterns and pitfalls  that stopped us from seeking what we wanted in the first place.

    This tension between what we feel we can have and "what were seemingly able to have is the niggling  suffering, the anxiety we feel. This is where we usually think it's easier to just give up. But we're never meant to let go of the part of us that knows we can have more. The intelligence behind that knowing is us—the real us. It's the part that believes in life and its possibilities. If you drop that, you begin to feel a little "dead" inside because you're dropping "you".

    So, if we have this capability but somehow life seems to keep us stuck, how do we break these patterns?

    Decide on a new course and make one decision at a time. This is good advice for a new adventure or just getting through today's challenges.

While, deep down, we know we can do it, our mind—or the minds of those close to us—usually says we can't.

    That isn't a reason to stop, it's just the mind, that little man or woman on your shoulder, trying to talk you out of something again. It has done it many times before. It's all about starting simple and doing it now.

    Decide and act before overthinking. When you do this you may feel a little, or large, release from the jail of your mind and you'll be on your way.

    In the short time Steve and Zach had been inside their tent packing their tools, wind-blown flame had skipped from the top of one tree to another. The long dry summer had turned the forest into a tinderbox.

    "Let's go! We can make it back to the river we crossed today!" Steve kept Brady on the lead and their heads down against the fire-wind. But Brady barked a sharp warning. Ahead of them lay a thick curtain of smoke across the track. They would never make it through that. The dog was pulling at his lead trying to draw them away from the smoke, and yet Steve was uneasy. It seemed to him that they were moving away from the river.

    Suddenly, Zach cried. "Zach!" Steve shouted. "Are you OK? Where are you?" Then Brady pulled Steve down a sharp slope(坡). At its base, Zach was rubbing his ankle.

    As Steve helped his friend to his feet, Brady lifted his head and snuffed(嗅) the smoke-laden wind. Next moment, the dog bounded away and disappeared. The boys shouted for him, but he didn't come back. Steve couldn't blame Brady for panicking. He himself wanted to run even though he didn't have a clue which way.

    Steve and Zach hadn't gone far when there was a familiar bark, and Brady came bounding, stopped directly in front of Steve and hit him with his head, pushing him back toward the slope they'd just climbed. But Steve didn't get it. Then Brady grabbed the boy's jeans and started pulling. The message was clear, but Steve hesitated. Of course he remembered Brady saving his uncle's life when the dog was much younger. Was he still sharp enough to get them through this?

    Nearby, a pine went up in a whoosh of smoke. Brady pulled again, urgently. "OK, big guy," Steve gritted(咬紧牙关). Brady led them back down the slope and into the trees. Not far from them fire was touching underbrush. Several times the big dog stopped. Often he changed directions. Steve was so tired that he just wanted to rest, but Brady wouldn't have it. The dog bullied both boys to go on. How long they'd walked Steve had no idea. He was almost numb when he heard it—the wonderful sound of rushing water!

    In Mexico, girls mark their fifteenth birthday with a celebration called Quinceanera. In the morning, the birthday girl goes to the church with her family and her best friends. She wears a beautiful dress. Later in the day, there is a huge party, with a big cake that matches the girl's dress, and a night filled with music and dancing.

    Becoming an adult is a very important life change, and Japan has a special holiday to celebrate this. The second Sunday in January is Coming-of-Age Day. On that day, everyone who had their twentieth birthday in the last year goes to their Town Hall for a special activity. Everyone dresses up, and many women wear beautiful dresses. The mayor makes a speech and gives presents to all the new adults.

    Some kids are afraid to start school, but six-year-olds in Germany can't wait. For them, Schulanfang is a big holiday. To celebrate a child's first day of school, parents or friends give the child a Zuckertuete, a big color box filled with candy and little presents. People take pictures of the kids holding their Zuckertuete, and there is a school party later for the parents with cake and coffee.

Whether in the home or the workplace, social robots are going to become a lot 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 companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately 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 deliver general answers to questions; it responds based on what it learns about each individual 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 applications in everything from education to health care and are already finding their way into some of these spaces.

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 intended to replace workers, but to work alongside other employees." We have technologies to train social robots to do things not for us, but with us," said Breazeal.
