In 1996, John Tierney suggested in the New York Times Magazine article that “recycling is garbage.” He wrote, “The money spent on recycling programs should have been spent on real social and environmental problems. Recycling programs not only increase energy use and pollution, but also cost more money than the disposal (处理) of plain old garbage. Recycling may be the most wasteful activity in modern America.”

Environmental groups were quick to express their disagreement. They wrote reports on how recycling programs in cities can reduce pollution and cost less than regular garbage pickup and disposal. Michael Shapiro, an official of the US Environmental Protection Agency(EPA), said that “recycling can be good value for money, although there's still room for improvements.”

But in 2002, New York City, a pioneer of recycling, found that its recycling program was losing money, so it stopped glass and plastic recycling. Other major cities watched closely to see how New York was dealing with its remaining program (the city never stopped paper recycling). But then it closed its last landfill (垃圾填埋地), and private companies out of New York raised prices due to the increased workload of carrying away and disposing New York's garbage. As a result, glass and plastic recycling became profitable for the city again, and New York brought the program back. According to Cecil Adams of The Chicago Reader, the lessons learned by New York are relevant everywhere. He believes that, if managed correctly, recycling programs should cost cities less than garbage disposal.

    Even though the benefits of recycling over disposal are many, keep in mind that it better serves the environment to “reduce and reuse” before recycling is even considered as a choice.

    People eat different things in different parts of the world.

    In south China we eat rice every day. Sometimes we eat it two or three times a day, for breakfast, lunch and supper. We usually eat it with fish, meat and vegetable.

    The Japanese eat rice, too. They also eat a lot of fish. They sometimes eat raw（生的）fish. In Africa, maize（玉米）is the most important food. People there make maize into flour（面粉）.From this flour they make different kinds of bread and cakes.

    In western（西方的）countries such as Britain, Australia and the U.S.A, the most important food is bread or potatoes. People there usually make their bread from wheat flour. They cook the potatoes in different ways. In England the most popular food is fish and chips. Sometimes people cook this food at home, but usually they buy it at the shop. They eat this food at home, in their work place, in the park or on the road. People call it "take-away" food.

    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．

    Entrepreneur and CEO of Tesla and Space X, Eldon Musk may have a little more time on his hands, as he's leaving his position on the board of the Open Al, according to a blog post.

    The departure is likely the result of Tesla's moving into the field of Artificial Intelligence(AI)，which he said in 2017 would be the “best in the world”and would even be able to “predict your destination, ”Musk will continue to “donate and advise the organization,” Open AI said in a blog post on Feb. 20, adding that “As Tesla continues to become more focused on AI, this will avoid a potential future conflict for Eldon.

    Musk and Y Combiner CEO Sam Altman co-founded the nonprofit enterprise in December2015, its mission is to develop safe artificial general intelligence and ensure those developments are made public. Open AI researchers published a paper on the site ArXiv, org, detailing the possible secure threats that come with“malicious”AI. In fact, Musk has heard the “evil AI”alarm several times, On Aug.11，2017, he warned that artificial intelligence poses a bigger threat to humanity, and he told a gathering of state governors that the government needs to regulate Al before robots start “killing people. ”

    Musk's departure from the Open AI board could mean big things for Tesla. As Eton Goodbye, a financial reporter, noted on Futurism, the move “could signal that Tesla is more deeply committed to their own AI projects than we thought. ”He added, “Those who have had their ears to any rumors (谣言)that Tesla is ready to deliver vehicles capable of Level 5autonomy could take this new Open Al development as a sign that the company is inching closer to that unapproachable goal, ”No company has reached that level of autonomy, which means that a driverless car could navigate any road under any conditions and that all the human “driver” would need to do is to input a destination.

    A court battle between German and Israeli archives （档案馆） over Kafka's manuscripts （手稿）raised literary, not just legal, questions. At the time of his death, Kafka hardly seemed like a candidate for world fame. He had a minor reputation in German literary circles. He published a few stories in magazines, but they received little attention.

    After he died in 1924, his friend Max Brod collected, edited and published his works - despite Kafka's own instructions in his will ordering the manuscripts to be destroyed - thus making Kafka a household name after his death. When the Nazis invaded Prague, Brod escaped to Israel, bringing the manuscripts with him. When he died in 1968, his manuscripts, together with those of Kafka, were transferred to his secretary Esther Hoffe.

    Even though Brod asked in his will that the manuscripts be given to a public archive, Hoffe sold some of them abroad for a great deal of money. Many of them eventually made it to the German Literature Archive. In 2007, she died and left her properties to her daughters. Then the case about the manuscripts started after the death of one of her daughters. The court said Hoffe had no rights, and could not have any such rights for the documents Brod took from Kafka's apartment after his death.

    Ironically, Kafka's stubborn homelessness and non-belonging in his works were accurately what ensured his place at the center of 20^th-century literature. W. H. Auden proposed that Kafka was to the cold, absurd 20^th century what Dante or Shakespeare had been to their times - the writer who captured the spirit of the age. That is why, in the end, it hardly matters whether Kafka's manuscripts stay in Germany or Israel. What counts is that we are all living in Kafka's world.

    Britain and France are two important countries in Europe. They are neighbors, separated only by the 20-mile seaway of the English Channel. And for most of the time that the two countries have existed, the French and the British have been rivals or even enemies. One conflict between the two countries lasted over 100 years, and the British and French were at war through the 18th century.

    There is no fighting now, of course. But there is still a strong sense of rivalry (敌对) between the two nations. That's why a recent survey in the UK caused a major shock.

It revealed (揭露) that one third of the British people would like to live in France. It also showed that twenty-one percent of British people would actually prefer to have been born in France.

    Many reasons were given. France has a better climate and a more relaxed lifestyle, with some of the longest holidays in Europe. It is thought to have better public services in every area from health to transport. People in France work shorter hours and enjoy longer vacations. And think of the food and wine!

    Estimates (估计) of the numbers of Britons living in France range from 100,000 to half a million. But it is not one-way traffic. Around 15,000 French people per year come to live in Britain, mainly settling in London. They are attracted by higher pay in Britain, lower taxes, a more dynamic lifestyle. Now it seems that people can go to the place that suits them best.
