Ahead of so-called Singles' Day on the 11th of this month，2013, online sales have already begun peaking.

    The leading e-business platform, tmall.com, has promoted(促销) its fifty-percent-off discount(折扣) to attract consumers. They are also trying to attract buyers through social media. Vice President of tmall.com Wang Yulei says more than 20 thousand online stores have joined the Double 11 Day sales. But this number has doubled. The final number of how many products going to be on sale has not been known yet. But so far, many more products planned to be put on shelves with discounts.

    During last year's Singles' Day, tmall.com, together with taobao.com, reached a record of 19.1 billion yuan in sales, which considered a milestone in the e-business history of China.

    Singles' Day was first started by Chinese college students in the 1990s as the opposite of Valentine's Day, a celebration for people without romantic partners. The timing was based on the date: Nov. 11—or double 11—for singles. Single young people would treat each other to dinner or give gifts to show love to someone and end their single status.

    But now, the Singles' Day has been promoted as a kind of grand craze just for the shopping season, thanks to thousands of discounted products being promoted online.

    Taobao.com was the first big e-retail platform which used the double 11 idea to promote sales. Taobao.com reached one million yuan worth of sales on that day in 2009, when they first promoted the Singles' Day idea. In 2010, the sales increased to 936 million yuan. The figure climbed up to 5.3 billion yuan in 2011, putting huge demand on shipping services. The figure doubled in 2012.

    E-commerce is considered to be replacing the traditional retailing industry, but the reality is that both sides are learning from each other.

    After years of research and testing, the hybrid car was developed and put on the market. It' s an interesting and exciting new improvement in today' s world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources.

    The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car' s engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

    A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144volt battery pack is actually recharged through the energy that is produced when the car's brakes are used. This is referred to as “regenerative braking”, because it generates electricity.

    Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

    Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, “I am low on gas”. When it completely runs out, the warning reads, “YOU ARE NOW OUT OF GAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

    Do you like air travel with a service dog? Air travel makes some people very nervous. The crowds, the noise and flying itself can cause unease. But there are classes people can take to help them defeat their fear of flying. And, let me introduce similar training for service dogs that suffer the same problem

Service dogs almost never leave the side of the people they care for. You will see them working on buses, trains and other public transport systems. But the busy environment found at an airport can trouble even the best trained working dog.

    People with disabilities depend on their dogs. They want the animals to safely guide them through security areas. They also need the dogs to remain calm on duty on the plane, even when the flying is not smooth. This takes special training. The Air Hollywood K9 Flight School is one place where such help can be found.

    The school has a piece of equipment that provides the sights, sounds and even the feel of an airplane in flight. It is called a flight simulator, which was built for filming airplane scenes in movies.

    Sandy Alexander has a disability that requires his two-year-old dog, Doc, to be always at his side. Mr. Alexander took the dog to the flight school to get him ready for plane trips. He says Doc did not like the bumpy part of the flight simulation( 模拟).

    Dog trainer Mary Segall is with Canine Companions for Independence. It provides dogs for people with disabilities. Ms Segall says successful training is based on a simple rule: preparation.

    " Dogs need to be exposed gradually and repetitively to stimulation, to the environment, to loud noises, to sounds and to other dogs so that when this experience happens to them on a daily basis, they are  able to act in a way that they're used to acting and that they don't get excitable."

    Dog owners who attended the training at Air Hollywood K9 Flight School say they now feel much more at ease about future flight. Their dogs also seem ready for take-off.

    Feeling sad is an important part of human nature.

    Jerome Wakefield, a professor at New York University, mentions that feeling down after your heart is broken is normal and may even be beneficial. Recently, Wakefield's students have been coming up to him because their parents are pressuring them to get help for their sadness; often the kids want no part of it. Rather than “listen to medicine,” they want to listen to their hearts. He believes these students' reaction represents an important part of human nature.

    Professor Diener, who has studied happiness for a quarter century, finds that the Scots and many other peoples like being sad, and don't appreciate being told they should be happier. “They say too much happiness might not be such a good thing, no matter where it comes from,” says Diener. He believes it's wrong for the “happiness industry” to send the message that not only can we all be happier, but we have a duty to be so. He argues that what is considered normal sadness is something we shouldn't avoid.

    Eric Wilson, a professor at Wake Forest University, made every effort to smooth out his habitual frown and wear a sunny smile, since a happy expression can lead to happy feelings. He even tried to be enthusiastic. When neither of these made him happy, he concluded that such a happiness movement was no good for him at all. Americans, love for happiness, he writes, creates an environment where sadness is not valued.

    These researchers believe the problem of continuous, extreme happiness should not be surprising, since negative emotions developed for a reason. Fear warns us against the presence of danger, for instance. Sadness, too, seems to be part of our DNA: monkeys, dogs and elephants all display something that looks like sadness. Being “up” all the time can cause you to play down very real threats.

    They believe that only by experiencing sadness can we experience the fullness of the human condition. Their studies show that when you are in a negative frame of mind, you become more logical and more creative. Abraham Lincoln was not limited by his dark moods, and Beethoven composed his later works in a sad state. Vincent van Gogh, Emily Dickinson and other artistic giants saw the world through a glass darkly.

    People who are somewhat unhappy are more motivated to improve both their own lot and the lot of their community. In contrast, people at the top of the happiness charts feel no such urgency. “If you're totally satisfied with your life,” says Diener, “you don't feel like working for change. Be careful when people tell you that you should be happier.”

    A ten-year-old from Howell, Michigan is being praised as a hero thanks to his persistence (坚持) that led to saving the life of an elderly neighbor. The event happened late in an evening when Danny DiPietro was being driven home from hockey practice by his mom.

    That's when the young boy noticed an open garage (车库) and a figure that he believed was a dog outside an apartment building near his house. Given the freezing cold weather, the young boy got a feeling that something was not right. But instead of dismissing it like most kids his age would have, he insisted that his mother, Dawn, find out what was going on. Dawn tried to make Danny believe that no one would leave a dog out in such cold weather, but he refused to take no for an answer.

    Dawn finally gave in and decided to drive to the area with the family dog and see if there was any truth to Danny's hunch (直觉). Sure enough, as she got closer to the apartment building she noticed a garage that was wide open and someone waving madly for help. Upon getting there, she realized that it was not a dog the young boy had seen, but Kathleen St. Onge. The 80-year-old had fallen down on some ice in her garage and had been lying there for two hours, unable to get up.

    Dawn rushed home to get her husband to help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they waited for the ambulance (救护车) to arrive. Though still in hospital, the elderly woman is recovering well and forever grateful to Danny, for following up on his hunch!

Amsterdam Destination Guide

    Amsterdam is one of the most popular travel destinations in the world, famous for its beautiful canals, top art museums, cycling culture and so on. It is the capital and most populous city in the Netherlands and often referred to as the “Venice of the North” because of its expansive system of bridges and canals. Here are some of the key points to remember as you plan your trip to Amsterdam.

    Must-See Attractions

    Most visitors begin their Amsterdam adventure in the Old Centre, which is full of traditional architecture, shopping centers, and coffee shops. You'll also want to check out Amsterdam's Museum Quarter in the South District, which is great for shopping at the Albert Cuyp Market and having a picnic in the Vondel park. The top museums to visit there are the Rijks musuem, the Ann Frank House, and the Van Gogh Museum.

    If You Have Time

    There are several other unique districts in Amsterdam, and you should try to explore as many of them as time allows. The Canal Ring is a UNESCO World Heritage Site that was originally built to attract wealthy home owners and is a center for celebrity spotting and nightlife today. The Plantage area has most of the city's museums, including the Jewish Historical Museum, the Scheepvaart Museum, and the botanical gardens.

    Money Saving Tips

    Unless you really want to see the tulips (郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise.

    Look for accommodations in Amsterdam's South District, where rates are generally cheaper than in the city center.

    Buy train tickets at the machine instead of the counter to save a bit of money.

    Instead of hiring a tour guide, hop on a canal boat. They're inexpensive and will give you a special point of view of the city.
