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 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 both sides are learning from each other.

    One of the most important aspects of an image is color. People are very sensitive to color, and different colors have different on people.

    In general, red is an exciting color, which creates an image of action, energy danger. Red is also the most frequently used color in flags. Eighty percent of the world's flags contain red. A study in Germany showed that football teams wearing red are more successful. Blue is a very calm color. Business executives usually wear dark blue suits. Blue is also a peaceful color. The flag of the United Nations is light blue. Yellow is associated with openness and freedom. Green is a very relaxing color. Surgeons nowadays wear green, because it's less tiring than white. Black creates an image of power and authority. It can also be a very threatening color. Gangsters and vampires often wear black, white is a pure and strong color. This is one reason why doctors wear white coats. We trust them more. Grey is a very anonymouscolor. People wearing grey don't want other people to notice them. Brown is the opposite of black. It's warm and friendly, while black is threatening

The hottest cities in the world

    The locations below are the hottest and also travel destinations on the planet.

    Bangkok

    According to the data, Bangkok is the hottest city on the planet﹣not because of any particularly impressive high temperatures, but because it is consistently hot all the year round. The city has an average annual temperature of 29℃, coupled with high dampness and an average of 128rainy days per year; while the highest temperature on record is 40℃.

    Timbuktu, Mali

    Located on the southern edge of the Sahara Desert, the African city of Timbuktu is similar to everything remote. It's also one of the hottest cities in the world, with a hot, dry climate offering record highs of 49℃. Throughout April, May and June, average maximum temperatures are beyond 40℃. Modern﹣day Timbuktu is slowly being swallowed by the desert and is certainly a shadow of the trade center that it once was.

    Ahvaz, Iran

    Built on the bank of the Karun River, Ahvaz is an industrial city with average highs of around 46℃ during July, its warmest month. The city's record high is 54℃, making it one of the world's hottest cities during the summer. Frequent sand and dust storms and an absence of rain from July to September mix with its sky﹣high temperatures.

    Kuwait City

    The wealthy capital of Kuwait is another competitor for the title of the world's hottest summertime city with average highs of over 45℃ from June to August. Nightfall brings little respite（缓解）, with after﹣dark low temperatures often over 30℃ during the summer months. Kuwait City's record high is 52℃, while it rains on an average of just 19 days per year.

    Inspired by a 9-year-old cyclist, Lauren Turner, who can only use one hand, a group of University of Guelph students has won an international award for their invention－a bike brake lever (刹车手柄) that pulls both the front brake and the back brake at the same time.

    Lauren Tuner was able to ride her bike, but not as confidently and quickly as her friends.

    “She couldn't use the front brake. She only used the back brake, but the front brake makes you stop twice as fast,” says Micha Wallace, who, with Katie Bell, Anina Sakaguchi and Andrew Morries won second prize in the James Dyson Award for their single-handed bike brake lever.

    "Lauren Turner tried the device (装置) first and she used it all last summer. She had no problems. It helped her go faster because she felt more confident in her braking abilities. She felt safer." says Wallace.

    The invention was the fourth-year design project for the four students. They designed, tested and created a prototype (模型) within a four-month period.

    When Wallace heard about the James Dyson Award on the news, she and her co-inventors entered their project in the U.K.-based contest, which rewards students designers who create products that improve the way we live. The students collected the runner-up prize－£2,000 for them and £500 for their school.

    As well, they had a chance to meet James Dyson, a U.K. famous inventor. Praising the students for their invention, Dyson says the single-handed brake lever could improve safety for all cyclists. By using both brakes at once, you could prevent the possibility of flying over the handlebars and ending up with an injury.

    The students hope to sell it to a major company. It may be used in other devices that require two hands for operation.

    Every morning, Ben Mumford starts his school day with math. At the age of ten, he is already working at GCSE level, but he does not always bother to get out of his pajamas (睡衣裤) in time for the class. He reads more books than most of his friends, studies science on the beach, and recently built a go-kart (卡丁车) in a technology lesson. Ben is happy and fulfilled, all, his mother believes, thanks to homeschooling.

    Homeschooling is not what it used to be. What emerged in the 1970s as a way for Catholic (信天主教的) parents to infuse (灌输) religion into their kids' education is now probably the fastest-growing form of education in the U.K. The number of homeschooled children has risen by about 40 percent over three years. Here are a handful of reasons why homeschooling makes sense in the 21^st century.

    Contrary to the name, homeschooling takes place in an actual home only a small part of time. A great deal of instruction happens in libraries, museums and community colleges. These experiences have the effect of helping kids mature much more quickly and developing a trait of open-mindedness.

    The key idea of homeschooling is that kids need to learn at the speed, and in the style, most appropriate for them. Without formal curriculum to guide their education, homeschoolers get the chance to explore a range of topics that might not be normally offered until high school or college. They can study psychology in the fourth grade, or finance in the eighth grade.

    The most common misunderstanding about homeschoolers is that they lack social skills. However, social media makes it convenient for homeschoolers of today to have just as much opportunity to make friends as kids studying in traditional schools. Meanwhile, they do not need to deal with the potential problems of being around kids in a school environment, including bullying, which might result in anxiety and depression.

    For most people, school is really good, and it works for them because they learn in the way that school teaches. However, there are so many different ways of learning and processing (处理) information and knowledge. It does not necessarily work for everyone.
