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.

Forget Cyclists, Pedestrians are Real Danger

We are having a debate about this topic. Here are some letters from our readers.

■ Yes, many cyclists behave dangerously. Many drivers are disrespectful of cyclists But pedestrians are probably the worse offenders.

People of all ages happily walk along the pavement with eyes and hands glued to the mobile phone, quite unaware of what is going on around them. They may even do the same thing while crossing a road at a pedestrian crossing or elsewhere. The rest of us have to evade (避让) them or just stand still to wait for the unavoidable collision.

The real problem is that some pedestrians seem to be, at least for the moment, in worlds of their own that are, to them, much more important than the welfare of others.

——Michael Horan

■ I loved the letter from Bob Brooks about cyclists (Viewpoints, May 29). I am afraid they seem to think they own the roads.

I was walking across Altrincharn Road one morning when a cyclist went round me and on being asked what he was doing he shouted at me.

The government built a cycle lane on the road but it is hardly used.

The police do nothing. What a laugh they are!

The cyclists should all have to be made to use the cycle lanes and wear helmets, fluorescent (发荧光的)jacket and tights at night and in the morning. They should pay some sort of tax and be fined for not wearing them.

——Carol Harvey

■ Cyclists jump on and off pavements (which are meant for pedestrians), ride at speed along the pavements, and think they have a special right to go through traffic lights when they are on red.

I was almost knocked down recently by a cyclist riding on the pavement when there was a cycle lane right next to him.

Other road users, including horse riders, manage to obey the rules so why not cyclists?

It's about time they had to be registered and insured, so when they do hit a pedestrian or a vehicle, or cause an accident, at least they can be traced and there might be an opportunity to claim.

    We all have different ways to navigate (导航) when lost—whether asking a stranger for help, consulting an old-school map or simply following our nose. But on a bike, the risks are higher. One wrong turn or that you're in a traffic jam with two lanes between your bike and the nearest pavement may ruin your good mood. Although cyclists, of course, managed to navigate before smart phones, cyclists can make two choices: a few stay calm and embrace getting lost, and the rest turn to a navigation app.

    Google Maps added a directions function for cyclists in 2015 in the US and Canada, and two years later across Europe. And while there are dozens of other apps now offering a similar service, Google Maps has the demerits for many, so the app seems to be falling behind expectations.

    As someone with no sense of direction, I knew it wouldn't be easy when I started cycling earlier this year. I appreciated that the app gave me two warnings before I needed to turn off a road, and automatically recalculated my route if I accidentally went off course. But still, it wasn't a smooth process. Google Maps thought I could cut across a double carriageway with no breaks in its barrier, assumed I knew what it meant when it told me to “head west”, and thought nothing of taking me the wrong way down a busy one-way street.

    Cyclists don't just want safety—they want convenience. Londoner Robson Smith regularly cycles between Clap ham and the City of London and would like to see Google Maps calculate routes where his bike is allowed on public transport and more choice of the type of routes he can take. “Google tends to calculate the most common and comfortable cycle routes. It would be better to have an option which included the fastest route, regardless of comfort,” he says.

    For this reason, Robson says he uses the app Cycle Streets instead. It offers a choice of four different route modes, based on the type the user wants, and saves previous routes. It also tells you how many calories a route burns, how many traffic lights you wilt encounter, and how busy it is.

    To err is human. To blame the other guy is even more human.

    Common sense is not all that common.

    Why tell the truth when you can come up with a good excuse?

    These three popular misquotes (戏谑的引语) are meant to be jokes, and yet they tell us a lot about human nature. To err, or to make mistakes, is indeed a part of being human, but it seems that most people don't want to accept the responsibility for having made a mistake. They naturally look for someone else who could be responsible for the problem. Perhaps it is the natural thing to do. The original quote about human nature went like this: “To err is human, to forgive, divine (神圣的).” This saying mirrors an ideal: people should be forgiving of others' mistakes. Instead, we tend to do the opposite —— find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a mark of great maturity.

    Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Common sense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine. Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything. People say that in a large company, “the right hand does not know what the left hand is doing.”

    And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of the common problems with making excuses is that people, especially young people, get the idea that it's okay not to be totally honest all the time. There is a corollary (直接推论) to that: if a good excuse is “good” even if it isn't honest, then where is the place of the truth?

Kids and science seem to be made for each other!

The basic science is a combination of thought and experiment called the scientific method. It's where you start with an idea, create a way to prove or disprove your idea, and show what you learned based on facts. Learning to follow this process helps you think logically (逻辑地) and carefully. These important thinking skills can be used in many areas of study. To give a child practice with these thinking skills is like giving vitamins (维生素) to a developing mind.

One of the greatest things we can teach our children is to love learning. Learning science is a great way to do so. Children are easy to be interested in science. Because much of science is hands-on, it attracts most children. Nothing makes a child sit up and take notice like the "WOW!" of a great science showing.

Science opens doors to many subjects at school. Building love for science can be helpful in other areas of study. For example, one cannot love science for very long without becoming good at its language-math! So science encourages children to study math. An interest in science is an interest in how things were once understood compared to how they are understood now. Thus studying science lends itself easily to studying history. And after you do an experiment, you need to write a lab report. Therefore, writing becomes an important part of science.

Science is the basic thing for much of our life. The science of farming shows how our food is produced; biomedical science keeps us healthy; even our beds these days are designed according to scientific facts. We almost eat, sleep and breathe with the help of science! When we prepare the next generation (一代) of voters, creators and policy makers, it is important to make sure they are not only comfortable but also good at science.
