Those who are used to looking through thousands of books in big bookstores may find Japan's Morioka Shoten a little strange. That's because this tiny bookstore that is located in Ginza, Tokyo sells only a single book at a time.

    Opened in May 2015, Morioka Shoten is the brainchild of Yoshiyuki Morioka. The experienced bookseller began his career as a bookstore clerk in Tokyo's Kanda district before branching out to open his own store. It was here while organizing book readings that he realized that customers usually came into the store with one title in mind. Morioka began to wonder if a store could exist by selling many copies of just one single book. In November 2014, he partnered with his two friends, to establish a unique bookstore with the idea of “A Single Room, A Single Book.”

    Like its offering, the bookstore is simple. The selections that are picked by Morioka change weekly and vary widely to attract customers with different interests. Recent choices include The True Deceiver, an award-winning Swedish novel by Tove Jansson, Hans Christian Andersen's Fairy Tales, and a collection of artist Karl Blossfeldt's photography of plants. Morioka has also chosen books written by famous Japanese authors Mimei Ogawa and Akito Akagi.

    To highlight his only offering, Morioka often uses clever methods. For example，when selling a book about flowers, he decorated his shop with the ones that had been mentioned in the book. He also encourages authors to hold talks and discussions so they can connect with customers. Morioka says his goal is for the customers to experience being inside a book, not just a bookstore!

    Risky as the idea might seem, things appear to be going well. Morioka says he has sold over 2,100 books since he opened it. Things can get better considering that his bookstore is becoming increasingly popular not just among the locals but also visitors from other countries.

    If a stranger offered you money to keep a suitcase in your spare room，would you accept? How about the other way round：if you had too many belongings，would you consider trusting someone you met online with their safekeeping? Anthony Paine believed enough of us would answer “yes” to these questions to launch his own startup(新兴公司)，Stashbee．His business links people with space to those who need it．

    And it's just one player in the booming “sharing economy”，an industry that relies on people renting out things like their beds，bikes and even parking spaces．Airbnb，a company valued at 200bn RMB，provides a platform for those renting property short-term．DogVacay pairs holidaymaking pet owners with pet-friendly hosts，and aims to be profitable by 2017．

    All their business models revolve around one simple word：trust．So，how does Stashbee measure up? BBC journalist Dougal Shaw decided to try it out for himself．He had some odds and ends to store while renovating his house，and met a host through the site who could keep them for 475 RMB for two months．All relatively smooth and painless．

    Heavyweights(行业巨头)in the traditional storage industry，such as Big Yenow and Access，aren't convinced．A representative from Access told Shaw he was skeptical about storing with “amateurs”．He considered 24／7(全天候) access to the items and better security as the main advantages of his service.

    Stashbee agree that dealing with security concerns is important，but say business success depends more on people overcoming a distrust of strangers we've been taught since childhood. They aren't alone．Companies such as Costockage，Roost and Spacer all run similar storage businesses，and are all relying on a shift in consumer attitudes．

    And the concept of social storage doesn't stop there．CityStasher believe there's a gap in the market for those who want to store things for extremely short periods of time．

    Would you try it out? It's a question of trust．

    MOOC, a massive(大规模的) open online course, aims at providing interactive discussion and open access via the web. In addition to traditional course materials such as videos, readings, and problem sets, MOOCs provide interactive user forums (论坛) that help build a community for the students, professors, and teaching assistants.

    MOOCs first made waves in the fall of 2011, when Professor Sebastian Thrun from Stanford University opened his graduate-level artificial intelligence course up to any student anywhere, and 160,000 students in more than 190 countries signed up. This new kind of online classes is shaking up the higher education world in many ways. Since the courses can be taken by hundreds of thousands of students at the same time, the number of universities might decrease greatly. Professor Thrun has even imagined a future in which there will only need to be 10 universities in the world. Perhaps the most impressive thing about MOOCs, many of which are being taught by professors at prestigious (声誉高的) universities, is that they're free. This is certainly good news for cash-strapped students.

    There is a lot of excitement and fear about MOOCs. While some say free online courses are a great way to increase the enrollment (注册) of students who are lack of resources, some critics (批评者) have said that MOOCs encourage an unrealistic one-size-fits-all model of higher education and that there is no replacement for true dialogues between professors and their students. After all, a brain is not a computer. We are not blank hard drives waiting to be filled with data. People learn from people they love and remember the things that arouse emotion. Some critics worry that online students will miss out on the social aspects of college.

    It's hard to talk to Dad sometimes. His silence about his feelings and thoughts made him mysterious and hard to see through. You could never break his hard shell and get to know him. And he seemed to want to stay that way too.

    But a year ago when my relationship with my wife and career took a hit, I needed my dad to pull back the curtain so I could see him as real and accessible. I was facing serious problems, and I wanted to know whether he had faced them before and how he had found his way, because I felt like I had lost mine. In desperation, it occurred to me that sending an email might be the key, so I wrote him one, telling him about my regrets and fears, and I asked him to answer, if he felt like it.

    Two weeks later, it showed up in my inbox: a much thought, three page letter. Dad, a 68­year­old retired technologist and grandfather of four, had carefully considered my message, and crafted a response. He mentioned his lost love, the foolish mistake he made in career and the stupid pride he had between him and his parents. He comforted me that “life will still find its right track despite many of its twists and turns”.

    I closed the email and started to cry, because I wished I had opened it up earlier but was grateful it wasn't too late. I cried because at first, in the midst of my own struggles, his letter instantly put me at ease. And I cried because in the end, it was so simple: I just had to hit “Send”.

    We've since had many email exchanges. This increasing communication opened a door into his world. My problems haven't been magically solved, but getting to know my dad better has made the tough stuff more manageable and life sweeter. It's hard to talk to Dad sometimes, but I'm glad I found a way to talk to mine.

    A study showed that the experiences children have in their first few years are important. These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion(万亿)connections in the brain of a three-year-old child.

    Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern"A-B-B". Another order was mu-ba-ge. This is the pattern “A-B-C”. The images showed that the part of the brain responsible for speech was more active during the" A-B-B" pattern. This shows that babies can tell the difference between different patterns. They also were sensitive to where it occurred in the order.

    Gervain is excited by these findings because the order of sounds is the building block of words and grammar." Position is key to language," she says. "If something is at the beginning or at the end, it makes a big difference: John caught the bear.' is very different from 'The bear caught John.'”

    Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books, the Internet, or smartphones－no matter how educational－doesn't appear to be enough for children's brain development. They carried out a study of nine-month-old American babies. They expected the first group who'd watched videos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies－regardless of whether they had watched the video or listened to the audio－learned nothing.

    Mr. Bean is an internationally recognized comedy character on TV and in films. He constantly gets into awkward and absurd situations, which greatly amuses audiences regardless of their nationalities or culture. The humour is always made clear through a series of simple and funny acts that rely purely on body language, which is universal.

    One of my favourite shows is that Mr. Bean has a meal in a fancy restaurant. After being seated at his table, Mr. Bean takes out a card, writes a few words on it, seals (密封) it in an envelope and places it on the table. After a moment, he looks back at the envelope but this time he looks surprised, as if he did not know it was there. He opens it to find a birthday card and delightedly puts it on the table for everyone to see.

    When he looks at the menu, an astonished look swiftly appears on his face. He takes all the money out of his wallet, counts it and puts it in a saucer (茶托). He then looks from the menu to the money with concern until he finds one thing that makes him smile. Then he orders a dish called "steak tartare". When the dish arrives, he is shocked to discover that "steak tartare" is actually raw hamburger. He makes an attempt to eat it, but it is clear from the look on his face that he finds the taste truly disgusting. He cannot hide his feelings, except when the waiter asks if everything is all right. When this happens, he smiles and nods, indicating that everything is fine. When the waiter is not looking, however, he busies himself hiding the raw meat anywhere he can reach-the sugar bowl, the tiny flower vase, inside a bun (小圆面包) and under a plate. He becomes so desperate in the end that he even hides some inside the purse of a woman sitting near him and throws some down the trousers of the restaurant's violinist!

    I like to watch Mr. Bean on TV, but I wouldn't like to meet someone like him in real life and I certainly wouldn't like to have dinner with him!
