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.

    You want to run across the street to catch the bus which is leaving soon? But wait! You'd better not. If a policeman sees you, you'll have to pay a fine. New traffic laws say that if people cross the street when the light is red, they can be fined as much as 50 yuan.

    Traffic accidents killed more than 100,000 people in China one year. Chinese cities have more cars than ever. Drivers and pedestrians must work together to make the streets safer.

    The law has new rules for drivers and pedestrians. Drivers have to slow down when they are close to crosswalks. If people are in a crosswalk, cars must stop to let them pass. There are rules for bus drivers, too. If bus drivers, smoke, drink or make phone calls while driving, they can be fined. Buses that carry too many people are also against the law.

    Pedestrians will have to walk more safely under the new law. They must cross streets at crosswalks. Also, they shouldn't climb over the fences (栅栏) along streets.

    Do you bike to school? It's not a good idea to carry classmates on the back. You could be fined 50 yuan. And stay in the bike lane (车道), when you' re riding. The big roads are for cars and buses.

    Do you like to ride your uncle's motorbike? When you put on your helmet (头盔), ask him to put one on, too. People on motorbikes must wear helmets, the new law says. If they don't, they'll have to pay 200 yuan.

    Do you ride in cars often? Don't forget to put on your seat belt (安全带), even if you're going for a short taxi ride. It could save your life.

    If you see a hit-and-run(肇事逃逸), tell the police. They may give you a reward (奖赏).And don't be afraid to help people to the hospital if they are hurt in an accident. Don't worry about money. The new law says that doctors must take care of them even if they can't pay right away.

    A new study from brain researchers helps explain how the human brain evolved or changed over time, to permit people to speak and write.

    Michael Ullman, the lead researcher, a professor at Georgetown University Medical School in Washington, D.C, has been studying language learning for more than 20 years.

    Ullman says his research shows that the human brain does not have a special area or system for making language. Over time we have simply reused or co-opted (指派) parts of our brain for language. And those parts, he says, are ancient-older even than humans themselves.

    "This study examines the theoretical framework (准则) that language is learned, stored and' processed in two ancient learning and memory systems in the brain."

    Ullman, Hamrick and the rest of the team looked at data from 16 other studies on language. They found that people learn language using two memory systems: declarative and procedural. Memorizing vocabulary, for example, is a declarative memory process. But learning grammar is, mostly, a procedural memory process.

    "Declarative memory, in humans at least, is what we think of as learning memory', such as, 'Oh, remember what you said last night' or things like that. And procedural motor memory is what we often call motor memory' such as how you learn to ride a bicycle." Or, Ullman adds, "These procedural memory skills become so deeply leaned that we are no longer aware that we are doing them."

    However, Ullman explains that the two long-term memory systems can share tasks. And, he adds, the adult brain uses the systems to learn language a bit differently than a child's brain.

    "Adult language learners of a second language may use their declarative memory for using grammar patterns. They think about it purposefully. For a child, the grammar may come more naturally. They don't have to think about the grammar rules before speaking."

    In addition to language learners, Ullman's study could help people who have a brain injury that affects speaking and writing. This knowledge can also help those who have learning disabilities such as dyslexia (阅读障碍). People with dyslexia have difficulty recognizing words and symbols accurately.

    We work with Cambridge County Council's Participation Team to create opportunities for young people to visit the University and learn more about it. The following events are scheduled for the 2019/2020 academic year.

    SuperStar workshops

    12 workshops are planned for young people aged 7 to 11. These half-day visits will be held throughout the year, at times when young people are not at school. If participants complete 8 of the 12 workshops, they will be awarded the nationally recognized SuperStar Crest Award.

    Please note, workshops will only run if we have a sufficient number of attendees (usually around 3+ participants).

    Explore University Days

    Explore University Days are for young people aged 12-15. Participants visit the University for two days and take part in a variety of university-related workshops, and other fun activities.

    Previous participants have joined in the following:

    • Visited the Sports Centre

    • Took part in a Neuroscience workshop

    • Enjoyed a two-course meal at a University College

    Dates will be confirmed in early December 2019, and a schedule for event will follow in the New Year.

    Events for post-16 students

    If you are studying for your post-16 qualifications and are considering applying for Cambridge or would like to find out more about a specific subject, the following events might be for you:

    • University and College Open Days

    • Subject Masterclasses

    • Cambridge Science Festival

    By now you've probably heard about the "you're not special" speech, when English teacher David McCullough told graduating seniors at Wellesley High School: "Do not get the idea you're anything special, because you're not." Mothers and fathers present at the ceremony 一 and a whole lot of other parents across the Internet — took issue with McCullough's ego-puncturing (伤自尊的) words. But lost in the uproar (喧嚣)was something we really should be taking to heart: our young people actually have no idea whether they're particularly talented or accomplished or not. In our eagerness to elevate their self-esteem, we forgot to teach them how to realistically assess their own abilities, a crucial requirement for getting better at anything from math to music to sports. In fact, it's not just privileged high-school students: we all tend to view ourselves as above average.

    Such inflated self-judgments have been found in study after study and it's often exactly when we're least competent at a given task that we rate our performance most generously, in a 2006 study published in the journal Medical Education, for example, medical students who scored the lowest on an essay test were the most charitable in their self evaluations, while high-scoring students judged themselves much more strictly. Poor students, the authors note, "lack insight" into their own inadequacy. Why should this be? Another study, led by Cornell University psychologist David Dunning, offers an enlightening explanation. People who are incompetent, he writes with coauthor Justin Kruger, suffer from a “dual burden": they're not good at what they do, and their very clumsiness prevents them from recognizing how bad they are.

    In Dunning and Kruger's study, subjects scoring at the bottom on tests of logic, grammar and humor -extremely overestimated'' their talents. Although their test scores put them in the 12th percentile (百分位数) they guessed they were in the 62nd. What these individuals lacked (in addition 9 clear logic, proper grammar and a sense of humor) was "meta cognitive skill" the capacity to monitor how well they're performing. In the absence of that capacity, the subjects arrived at an overly hopeful view of their own abilities. There's a paradox here, the authors note: The skills that lead to competence in a particular domain are often the very same skills necessary to evaluate competence in that field? In other words, to get better at judging how well we're doing at an activity, we have to get better at the activity itself.

    There are a couple of ways out of this double bind. First, we can learn to make honest comparisons with others. Train yourself to recognize excellence, even when you yourself don't possess it, and compare what you can do against what truly excellent individuals are able to accomplish. Second, seek out feedback that is frequent, accurate and specific. Find a critic who will tell you not only how poorly you're doing, but just what it is that you're doing wrong. As Dunning and Kruger note, success indicates to us that everything went right, but failure is more ambiguous: any number of things could have gone wrong. Use this external feedback to figure out exactly where and when you screwed up.

    If we adopt these strategies — and most importantly, teach them to our children — they won't need parents, or a commencement (毕业典礼)speaker, to tell them that they're special. They'll already know that they are, or have a plan to get that way.

In summer holiday, the kids are out of school, so it is a good time to plan for a family travel. However, it's not easy to prepare for a family travel. Here are four travel apps(应用程序) to make your trip more relaxing.

Yuggler

Search nearby for family-friendly activities, from free events to worthwhile attractions. Use Yuggler to plan for what to do each day, based on the weather or the type of entertainment your kids want or need, and look through reviews written by parents who've been there. So instead of paying $20 per person for entrance to the big museum, you can locate just-as-fun spots with zero admission, saving a family of $80.

Sit or Squat

Held by Charmin, this app uses your phone's built-in location finder to find out the closest public restrooms. Perhaps more importantly, Sit or Squat provides the restrooms'cleanliness scores, which are made by the users who have been there. It is quite convenient.

My Disney Experience

The official Walt Disney World app's interactive map(互动地图), which uses your tool's GPS, helps you find restaurants, restrooms, and attractions nearby. You can also access real-time wait times for popular rides and character appearances, meaning you're making the most of your time.

Wi-Fi Finder

Find free Internet near your current location in a minute. Wi-Fi Finder works offline too. Before you head out, download the offline database(数据库) to your phone, so you won't waste data while searching for a hotspot, which is key during an international trip. You'll save as much as $15 off the hotel Wi-Fi cost.
