People always think men are more skilled than women in driving. Nowadays women appear to have a positive image of themselves as safer drivers than men.

    In a survey done for insurer MetLife, 51% of women said they drive more safely. The evidence is on their side: Men are 3.4 times more likely than women to get a ticket for careless driving and 3.1 times as likely to be punished for drunk driving. “Women are on average less aggressive and more law abiding (守法的) drivers, which leads to fewer accidents.” the report says. However, not all male drivers share the same opinion. Of the men surveyed by MetLife, 39% claimed male drivers were safer. The findings did back them up on one point: automotive knowledge. The report showed that more men are familiar with current safety equipment such as electronic stability control, which helps prevent rollover accidents.

    Auto safety unavoidably matters to money. Insurance companies focus on what classes of drivers have the lowest dollar amounts of claims, and for now, that mainly includes women. In general, women pay about 9% less for auto insurance than men. A study by the website Insweb also showed that auto insurance rates are lower for women in most states. Among individual states, women get the greatest advantage in Wyoming (where they pay 20% less), South Dakota and Washington, D. C., where their insurance costs are 16% lower.

    “More than 11,900 male drivers died in U.S. traffic accidents in 2009, compared with just under 4,900 women drivers,” according to the study. “Based on miles traveled, men died at a rate of 2.5 deaths per 100 million miles traveled, v.s. 1.7 deaths for women.”

    Those accustomed to browsing (浏览) through thousands of books in large 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 (脑力劳动成果；发明；主意) of Yoshiyuki Morioka. He began his career as a bookstore clerk in Tokyo's Kanda district before branching out into opening his own store. It was here while organizing book reading and signing 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 multiple copies of just one single book. In November 2014, he partnered Masamichi Toyama to establish a unique bookstore with the philosophy of "a single room with a single book".

    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 Andersen's fairy tales, and a collection of Karl Blossfeldt's photography of plants. Morioka has also selected books written by a famous Japanese author Mimei Ogawa.

    To highlight his only offering, Morioka often uses clever tricks. For example, when selling a book about flowers, the storekeeper decorates his shop with the ones that have 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 to let customers experience being inside a book, not just a bookstore.

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

    T-shirts out; uniforms in

    School uniforms are becoming more and more popular across the U.S.A. That's no surprise, because they offer many benefits. They immediately end the powerful social sorting and labeling (标记) that come from clothing. If all students are dressed in the same way, they will not pay too much attention to their clothing, and some of them will not be laughed at for wearing the “wrong” clothes.

    Some people are against the strict rule of school uniforms, but they do not realize that students already accept a kind of rule — wanting to look just like their friends. The difference is that the clothing students choose for themselves creates social barriers; school uniforms tear those barriers down.

    As in other places, uniforms remind the wearers of their purposes and duties. For example, when a man or woman puts on a police uniform, he or she becomes, for a time, the symbol of law and order. The uniform means to the wearer his or her special duties and sends the same message to everyone the wearer meets. People with different jobs wear uniforms of one kind or another. For students, the school uniform reminds them that their task for the six or seven hours they are in school is to get an education.

    Some parents are unhappy about uniforms, saying that school uniforms will affect their children's “creativity.” First, the clothes students choose to wear do not necessarily express the individuality. They just copy their classmates. Second, students have the rest of the day to be as creative as they like. While they're in school, their job is to master reading, writing, and math; this should take up all the creativity they have. Mastery of those skills will be good for the students to build up their creativity in every way.

    When you are sitting in class, have you ever drawn pictures in the margins (页边的空白处) of your notebooks? If so, you are doodling. Many people think of doodling as a distraction (分心) from more important things. But it might be just the opposite.

    One study shows that doodling may help you remember things you hear 29% more. Besides, doodling can help you think creatively. Walking away from a problem to draw might actually help you solve it. When you come back, you'll have a fresh perspective and figure out an answer more quickly.

    An author named Sunni Brown wrote a book on doodling. She argues that doodling is a tool that can help people think. In fact, she runs a business that helps companies improve organization and planning through doodling. Brown believes doodling is helpful because it includes many ways of learning. You learn in four ways: seeing, hearing, reading or writing, and through movement. The more ways you use, the better you learn. And when you doodle while listening to a lecture, you use all four.

    You might think that being good at drawing is important for doodling. But if the point of doodling is to help you think, then it doesn't matter what the picture looks like. Even if you're not an artist, doodling can help you. So next time you need help focusing, pick up a pen and doodle away!

    Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy (星系).The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. It was captured by the Event Horizon Telescope (EHT).

    The announcement was made in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo. Details have been published today in Astrophysical Journal Letters.

    Prof Heino Falckc, of Radboud University in the Netherlands, who suggested the experiment, told BBC News that the black hole was found in a galaxy called M87. "What we see is larger than the size of our entire Solar System," he said. "It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe."

    The image shows an intensely bright "ring of fire", as Prof Falckc describes it, surrounding a perfectly circular dark hole. The bright halo is caused by very heated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth. The edge of the dark circle at the center is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull (万有引 力）,not even light can escape.

    "It is remarkable that the image we observe is so similar to that which we get from our theoretical calculations. So far, it looks like Einstein is correct once again." said Dr Ziri Younsi, of University College London -who is part of the EHT cooperation.

    Chinese scientists were involved in the observation through a telescope in Hawaii. They were also highly involved in follow-up data processing and theoretical analysis, said Shen Zhiqiang, head of the Chinese Academy of Sciences' Shanhai Astronomical Observatory and a member of the EHT international team.

    Shanghai and Taipei were selected as two of the cities to hold news conferences, together with Washington, Brussels, Santiago and Tokyo, a recognition of China's contribution.

    "In the fields of astronomy, radio astronomy, and space astrophysics, China has made a significant contribution to this global project," Falcke said.

    Many of us just laugh it away when they are told incredible (难以置信的) stories about other people, but I have a deep interest in these stories and I prefer to believe they are true. Here's one I collected from a total stranger.

    "Well, I was 11 when my family arrived at Fern Lake overlooking Trail Ridge Road in Rocky Mountain National Park. It was so beautiful to look miles across the Rockies and thousands of feet below into the valley. My parents were busy getting lunch out of the trunk so I climbed over the wooden fence to get closer to the cliff edge in the hope that I wouldn't miss any beautiful sight down there.

    I started down a little hill but soon started sliding on loose pebble rocks(鹅卵石). I fell on my back, but kept going faster and faster to what seemed the edge of the world (a 2,000 foot drop). In seconds I knew I was going to die. My feet and legs went first over the edge at a high speed. Then suddenly I felt two hands push hard on my chest and stopped me dead. My heart was racing and I slowly inched my body back to where I finally could make it back up the hill.

    My father was waiting there and screaming at me for doing such a dangerous stunt (特技). I tried to tell him and my mom about the hands that held me back, but to this day they don't believe me. They thought I was just trying to get out of trouble with a made-up story.”

    We parted ways, but I assured her that I believed every word of her story. I could see a little surprise and happiness on her face.

    That's why I always ask people to share their miracles (奇迹). Each real story makes my days full of hope and gratefulness.
