The sharing economy, represented by companies like Airbnb or Uber, is the latest fashion craze. But many supporters have overlooked the reality that this new business model is largely based on escaping regulations and breaking the law.

    Airbnb is an Internet-based service that allows people to rent out spare rooms to strangers for short stays. Uber is an Internet taxi service that allows thousands of people to answer ride requests with their own cars. There are hundreds of other such services.

    The good thing about the sharing economy is that it promotes the use of underused resources. Millions of people have houses or apartments with empty rooms, and Airbnb allows them to profit from these rooms while allowing guests a place to stay at prices that are often far less than those charged by hotels. Uber offers prices that are competitive with standard taxi prices and their drivers are often much quicker and more trustworthy.

    But the downside of the sharing economy has gotten much less attention. Most cities and states both tax and regulate hotels, and the tourists who stay in hotels are usually an important source of tax income. But many of Airbnb's customers are not paying the taxes required under the law.

    Airbnb can also raise issues of safety for its customers and trouble for hosts' neighbors. Hotels are regularly inspected to ensure that they are not fire traps and that they don't form other risks for visitors. Airbnb hosts face no such inspections.

    Since Airbnb is allowing people to escape taxes and regulations, the company is simply promoting thefts. Others in the economy will lose by bearing an additional tax burden or being forced to live next to an apartment unit with a never-ending series of noisy visitors.

    The same story may apply with Uber. Uber is currently in disputes over whether its cars meet the safety and insurance requirements imposed on standard taxis. Also, if Uber and related services flood the market, they could harm all taxi drivers' ability to earn a minimum wage.

    This downside of the sharing needs to be taken seriously, but that doesn't mean the current tax and regulatory structure is perfect.

    I study English literature at university and have always been proud of Britain's literary heritage（文学遗产）. Some British authors that you may have heard of are Charles Dickens and Jane Austen. These writers are famous all over the world because their books have been translated into many different languages. In the UK, their novels are celebrated as some of the best that have ever been written. We say that these novels are “classic” because they are still read and enjoyed years after their publication.

    I read classic novels because they are part of my university lessons but also because I enjoy them. They can teach you a lot about how people used to live and what society was like in the past. Novels like Hard Times by Charles Dickens remind us of the poverty in London during the Industrial Revolution while Jane Austen's fiction shows us what family life was like in the 18th century.

    Classic novels usually have memorable stories land interesting characters. One of my favourite books is Charles Dickens Great Expectations. It is about a boy called Pip who suddenly receives a lot of money from a mysterious supporter. As he grows up, his character changes: he becomes quite selfish and mean. Another important character is Miss Havisham. When she was young, her fiancé ran away on their wedding day. She lives in a dark house and still wears her wedding dress. She is a fascinating character, both sad and scary.

    Reading classic novels enriches my knowledge and life experience. And it has become part of life.

    You've probably visited the Tian'anmen Gatetower—the landmark building of Beijing, but you may not have heard of Kuai Xiang. Along with him, the following remarkable architects all took the center stage at their times.

    Kuai Xiang(1399—1481)

    Tian'anmen Gatetower is universally considered the brainchild of Kuai Xiang. By following in the footsteps of ancient homebuilders, he successfully presented the Emperor Judy with a grand wooden structure which has stood the test of time for almost 600 years. Visitors are also hooked on its delicate paintings.

    Ieob Ming Pei (1917-present)

    His motto is: Traditions should be sealed in glass boxes at museums. He is always struggling with innovation. Although under grilling from French conservative critics, he still planted a glass pyramid into the courtyard of the Louvre. His other works include John F. Kennedy Library, Beijing Fragrant Hill Hotel and Suzhou Museum.

    Zaha Hadid(1950-2016)

    In 2004, she became the first woman to win the Pritzker Architecture Prize, the Nobel Prize for architecture. She used tricks to maximize available space. Her fluid-style works pioneer the concept of micro-living. The curves(曲线) of Guangzhou Opera House perfectly match the rise and fall of its surrounding buildings, forming a unique view.

    Meng Fanchao (1959-present)

    Many people dismissed the building of a mega bridge as a pipe dream, but Meng Fanchao turned this into reality by building Hong Kong-Zhuhai-Macao Bridge. This longest cross-sea bridge, when viewed afar, looks like a dynamic dragon braving the rolling waves of Lingding Sea.

    I start every summer with the best of intentions: to attack one big book from the past, a classic that I was supposed to have read when young and ambitious. Often the pairings of books and settings have been purely unthinking: "Moby Dick" on a three-day cross-country train trip: “The Magic Mountain” in a New England beachside cottage with no locks on the doors, no telephones or televisions in the rooms, and little to do beyond row on the salt pond. Attempting "The Man Without Qualities" on a return to Hawaii, my hometown, however, was less fruitful: I made it through one and a quarter volumes (册), then decided that I'd got the point and went swimming instead.

    But this summer I find myself at a loss. I'm not quite interested in Balzac, say, or “Tristram Shandy.” There's always War and Peace, which I've covered some distance several times, only to get bogged down in the "War" part, set it aside for a while, and realize that I have to start over from the beginning again, having forgotten everyone's name and social rank. How appealing to simply fall back on a favorite once more into “The Waves” or “Justine,” which feels almost like cheating, too exciting and too much fun to properly belong in serious literature.

    And then there's Stendhal's “The Red and the Black,” which happens to be the name of my favorite cocktail of the summer, created by Michael Cecconi at Savoy and BackForty. It is easy to drink, and knocking back three or four seems like such a delightful idea. Cecconi's theory: "I take whatever's fresh at the green market and turn it into liquid." The result is a pure shot of afternoon in the park, making one feel cheerful and peaceful all at once, lying on uncut grass with eyes shut, sun beating through the lids…

    At the age of seven, while his friends were spending their allowances on things like candy and toys, Jose Adolfo Quisocola was busy saving money for basic purchases. To try to get his peers（同龄人） to do the same, the boy from Peru came up with the idea of an eco-bank, the Bartselana

    Student Bank, which allows kids of all ages to become financially independent while also helping the environment.

    Set up in 2012, the bank is the world's first bank for kids. To become a member, a kid has to bring in at least 5 kilograms of solid waste and set a savings goal. Once accepted, all bank “partners” are required to deposit at least one additional kilogram of recyclables on a monthly basis and observe other requirements, such as attending financial education and environmental management workshops.

    The waste accumulated is sold to local recycling companies, who, thanks to Jose's efforts, pay a higher-than-market rate for everything brought in by the bank members. The money received is placed in the personal account where they collect until the savings goal is reached. The account holder can then withdraw the money, or choose to leave it and continue to grow for a bigger target. “At the beginning, my teachers thought I was crazy or that a child could not undertake this type of project,” Jose recalls, “They did not understand that we are not the future of the country but its present. Luckily, I had the support of the school headmaster and an assistant in my class.”

    The boy's efforts paid off, and by 2013, the bank had over 200 members, who brought in one ton of recyclable waste. Today, the eco-bank, which now has the support of several local institutions, boasts ten educational centers. They are designed to teach the over 3,000 students, aged 10 to 18, to become financially independent, use their money wisely, and help the environment.

    Not surprisingly, Jose's efforts have earned him several national and international awards. On November 20, 2018, Jose won Children's Climate Prize, which comes with a medal and $5,500 in prize money and is given to a child or youth who has accomplished an extraordinary achievement for the climate or environment.
