Each year the Pritzker Architecture Prize (普立兹克建筑奖) goes to a star designer with a long list of attractive buildings around the world. This year's winner is a little different.

    Shigeru Ban has designed museums, homes and concert halls. But Ban is best known for a more simple kind of work: the temporary (暂时的) buildings for people who became homeless after disasters.

    Ban may be the only designer in the world who makes buildings out of paper — cardboard paper tubes (管). Ban actually tested the strength of cardboard tubes, and said he was surprised by what he had discovered. He has used them to build temporary buildings in Japan, Haiti, China and elsewhere.

    “After a disaster, the building material is going to be more expensive,” Ban explains. “But the paper tube is actually not a building material. It is cheap and plentiful. We can get the material easily anywhere. And unlike costs for traditional building materials, the price of paper tubes doesn't jump after an earthquake or flood. The tubes are also lightweight, so you don't need heavy machines to work with them.”

    Ban started using cardboard paper tubes in the 1980s. At that time he had just graduated from the architecture school, and he was looking for a cheap substitute for wood. So he started reusing the paper cardboard tubes that were left over from rolls of paper in his office.

    Ban was born in Tokyo and studied architecture in the U.S. before moving back to Japan to start his practice. Some of Ban's temporary buildings have become permanent (永久的), like the paper church he built after the 1995 earthquake in Kobe, Japan.

    At least 35 percent of Beijing households will be covered by family doctor service at the end of this year. All local households will enjoy the service as of 2020, according to the Municipal Health and Family Planning Commission.

    It is good that Chinese communities can expect more general practitioners(从业者)，who do not specialize in any particular area of medicine but who are able to treat the general health problems for people of all ages. By the end of last year over 8 million residents in Beijing had reportedly signed up for family doctor services, accounting for more than 40 percent of the city's permanent population.

    Since 2009 China has launched scores of programs nationwide to ensure citizens have fairer access to elementary public health services ，among which the introduction of family doctors has been one of the most successful. Some regions have issued guidelines on the promotion of the family doctor service. And four months ago, Premier Li Keqiang said in this year's Government Work Report that the service should cover at least 85 percent of the Chinese cities this year.

    The expanding coverage, however, may not guarantee more residents will be offered quality medical services.

    Family doctors in some places rarely visit the families they are assigned to, and some of them have been struggling to solve patients problems either because of their unfitness or because they have too many households to attend to. In some cases, a family doctor might be assigned to see hundreds of residents a day.

    That highlights the need to better the arrangement of medical resources and to offer proper encouragement to family doctors, who should get patients to make appointments rather than employ temporary arrangements.

    As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input (输入) Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（笔画）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it."

    "I'm not in the mood to write when faced with a pen and paper."

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital, said, "Chinese characters enjoy both practical and aesthetic（审美的）value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

    Getting stuck in a traffic jam is one of the most boring problems for people living in big cities. The fact that you're moving so slowly leads too stress, anger and the wish that your car could just fly over the traffic like an airplane.

    Soon, however, that wish could come true .On May 8, US car-renting company Uber showed off what it described as "the transportation mode of the future: on-demand air transport," reported ABC News.

    According to Nikhill Goel, head of products for Uber Air, the company's air taxi service may launch test flights in the US cities of Dallas and Los Angeles, as well as Dubai in the United Arab Emirates, as early as 2020. If everything goes according to plan, passengers will be able to fly to work by 2023.

    When the Olympics comes to Los Angeles in 2028. Uber "expects to have hundreds, if not thousands, of its aircraft in the skies." Goel told Newsweek.

    So what would Uber's flying vehicles be like?

    They are small, electric aircraft that take off and land vertically (垂直地) , and they give off zero emissions (排放) and are quiet enough to operate in cities .

    Just like an airplane, the vehicles will have fixed wings to help them glide. But while a helicopter has just one big fixed rotor (定量). Uber's vehicles will have multiple rotors , which will help increase fuel efficiency (效率) while reducing emissions and noise.

    Because of these fixed wines and multiple rotors. Uber's flying taxis "should be quieter and safer than a helicopter." reported ABC News.

    However, the service still has a long way to go before it's ready to accept passengers. For example, to avoid any potential accidents. Uber is working with NASA to study air traffic control problems associated with low-flying aircraft. But just as Dubai's Mayor Betty Price said in a news release. "This program is revolutionary and future -oriented (面向未来的)."

    A typical child plays many roles, such as friend, neighbor, son or daughter. Simply reminding children of that fact can lead to better problem-solving and more flexible thinking, according to new research from Duke University.

    Better problem-solving was just one positive finding of the study, said lead author Sarah Gaither, an assistant professor of psychology and neuroscience at Duke. After thinking about their own various identities, children also showed more flexible thinking about race and other social groupings—a behavior that could be valuable in an increasingly diverse society.

    In a series of experiments, Gaither and her colleagues looked at 196 children, ages 6 and 7. In an experiment, one group of children was reminded that they had various identities, such as son, daughter, reader or helper. A second group of children was reminded of their multiple physical attributes, such as a mouth, arms and legs. All the children then needed to handle a few tasks

    Children who were reminded of their various identities showed stronger problem-solving and creative thinking skills. When shown pictures of a bear staring at honey-filled beehive(蜂窝)high up in a tree, these children had more creative ideas for how the bear might get the honey, such as turning over a bowl so that it became a stool(凳子). In other words, they saw a new use for the bowl. Children who were reminded of their multiple roles also showed more flexible thinking about social groupings. When asked to categorize different photos of faces, they suggested many ways to Spso. They identified smiling faces such as unsmiling ones, and old and young faces. The other children, meanwhile, primarily grouped people's faces by race and gender(性别).

    The-study suggests ways to promote flexible thinking for the young, which could be especially valuable for teachers." Gaither said.

    "We have this tendency in our society to only think about ourselves in connection with one important group at a time," Gaither said. "When kids think that they have various identities, they show greater abilities."
