     The idea of inventing an international language is not a new one. Over the past 180 years, linguists (语言学家) have created over ten different languages that are based on German, Spanish, and English. One of these was Basic English.

     By 1923 the First World War had been over for five years, but Europe was still recovering from its effects. Charles Kay Ogden, a linguist and writer, was running several bookshops in Cambridge. He published The Meaning of Meaning (1923), a book describing how we use language. The book received high praise, which drove Ogden to design an international language — something that was much simpler than English. In 1930 Ogden's book Basic English: A General Introduction with Rules and Grammar was published.

     Perhaps it takes about seven years for one to become a good English speaker. Ogden believed that Basic English could be learned in seven weeks. There were only 850 words and the grammar was very simple.

     The language attracted the attention of educators all over the world, but its development was stopped by the Second World War. After the war, both the British Prime Minister Winston Churchill and the President of the United States Franklin D. Roosevelt looked for ideas that might bring world peace. They both gave speeches that encouraged the use of Ogden's international language. In the past 60 years, the language has had some success. In some parts of East Asia, teachers are still using Ogden's word lists.

     However, in the main, the language has disappeared. Because there are many more non-native than native speakers of English, recently some linguists have asked whether we should give careful consideration to Ogden's ideas again. And the Wikipedia website (www.wikipedia.org) has started a version (版本) written in Basic English for non-native learners of the language. Search for it on the Internet now!  

    It's true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There^'s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: The global warming over the last half - century has been caused mainly by human activity.”

    You may not believe that humans could change the planet's climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.

    Of course, the earth's climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth's going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build - up of greenhouse gas in the atmosphere - not the warming we would expect from other possible causes.

    Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren't carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

    The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths-one with human influence and one without. That obviously isn't possible, and so most scientists are careful not to state human influence as an absolute certainty.

    Watching wooden dolls come to life may not be one of the most popular forms of entertainment today, but with over twenty years' experience, talented puppeteer (木偶表演者) Peter Roberts has earned himself the title "master puppeteer" because of his great ability to turn puppets into believable, almost living characters. "People are quite often surprised to hear what I do for a living and have little appreciation of puppy as a form of entertainment. But while the exact origins of puppet theatre are unknown, it has been popular in many cultures and may have been the very first kind of theatre," he explains.

    Roberts' shows are highly original. "A puppet show can involve anything from clowning(傻逗) to storytelling," he says.  Equally diverse are the audiences he performs for. "Some are attracted by the puppets themselves, while others enjoy the dialogue." Roberts believes that this form of entertainment can be appreciated by people of all ages and cultures.

    Roberts' interest in puppets started when he received some beautiful glove puppets one Christmas. He started putting on shows with these for family and friends and then moved on to handmade Chinese string puppets. Learning mostly from books and personal experience, he explains, "I was already spending most of my free time carving puppets and putting on shows, so I hardly noticed the change from students to full-time professional puppeteer."

    The puppets are designed specifically for each show, which is extremely time consuming. According to Roberts, "Sometimes what you expect and what you actually create in the end are two very different things. I've made some of my best puppets 'accidentally'."

    When most people hear the word "puppetry", they more than likely think of a way of keeping children entertained at birthday parties. Certainly the subject matter will be expected to be light-hearted rather than serious. However, Roberts wants to point out that puppets convey serious messages sometimes." he says.

    Houses have been getting progressively "smarter" for decades, but the next generation of smart homes may offer what two Case Western Reserve University scientists are calling an "Internet of Ears."

    Today's smart home features appliances, entertainment systems, security cameras and lighting, heating and cooling systems that are connected to each other and the Internet. They can be accessed and controlled remotely by computer or smartphone apps.

    But a group of electrical engineering and computer science professors in the Case School of Engineering have been experimenting with a new suite of sensors (传感器). This system would read not only the vibrations (震动), sounds and even other movements associated with people and animals in a building, but also any slight changes in the existing electrical field.

    While there still maybe a decade or so away, the home of the future could be a building that adjusts to your activity with only a few small, hidden sensors in the walls and floor with-out the need for monitoring cameras.

    "We are trying to make a building that is able t0 61isten' to the humans inside," said Ming-Chun Huang, an assistant professor in electrical engineering and computer science. "We are using principles similar to those of the human ear, where vibrations are picked up and our algorithms (计算程序) recognize them to determine your specific movements. That's why we call it the 61nternet of Ears'. "

    “There is actually a constant 60 Hz electrical field all around us, and because people are somewhat conductive, they short out the field just a little," Huang said. "So, by measuring the disturbance in that field, we are able to determine their presence, or even their breathing, even when there are no vibrations associated with sound.”

    Huang said they have used as few as four small sensors in the walls and floor of a room.

    As for privacy concerns, the system would not be able to identify individuals, although it could recognize people's different ways of walking.

Eco-Resort Management

    Ecotourism is often regarded as a form of nature-based tourism and has become an important alternative source of tourists. In addition to providing the traditional resort-leisure product, it has been argued that ecotourism resort(度假村) management should have a particular focus on best-practice environmental management. Couran Cove Resort is such a tourist attraction located on South Stradbroke Island, Australia.

    Sustainable(可持续的) Practices of Couran Cove Resort

    South Stradbroke Island is separated from the mainland by the Broadwater, which is home to a wide range of plant communities. Located on the offshore island, the Resort is only accessible by means of water transportation. It provides hourly ferry service from the harbour on the mainland to and from the island. Within the Resort, transport modes include walking trails, bicycle tracks and the beach train. The reception area is the counter of the shop which has not changed in 8 years at least. The accommodation is an octagonal(八角形的) building. These are large rooms that are clean but the equipment is old and in some cases just working. The ceiling fan only works at high speed for example. Beds are hard but clean. There is a television, a radio, an old air conditioner and a small fridge in each room.

    As an ecotourism-based resort, most of the planning and development of the attraction has been concentrated on the need to co-exist with the natural environment of South Stradbroke Island to achieve sustainable development.

Water and Energy Management

    There is groundwater at the centre of the island, which has a maximum height of 3 metres above sea level. The water supply is recharged by rainfall and is commonly known as an freshwater aquifer(含水层). Couran Cove Island Resort obtains its water supply by tapping into this aquifer and collecting it through a pipe. In order to narrow the water uses, all laundry activities are carried out on the mainland. The Resort uses LPG power station rather than a fuel oil station for its energy supply, supplemented(补充) by wind power, which has reduced greenhouse emissions by 70%. Hot water in the eco-cabins and for some of the Resort's vehicles is solar-powered. Water efficient fittings are also installed in showers and toilets. Visitors who stay at the Resort are encouraged to monitor their water and energy usage by an in-house television system, and are rewarded with prizes (such as a free return trip to the Resort) accordingly if their usage level is low.

    Evaluation

    In three years of operation, Couran Cove Island Resort has won 23 international and national awards. It has effectively implemented contemporary environmental management practices. However, the Resort's growth will eventually be limited by its carrying capacity, and quantity control should be incorporated in the management strategy of the Resort.

    We've heard of robots and AI（Artificial Intelligence）taking human jobs, but I bet mayors（市长）don't really think their jobs can be threatened any time soon. They were wrong, and the AI running for the mayor of a Tokyo district was clear proof of that.

    AI can't legally nm for high-ranking public management positions yet, but one mayoral candidate from Tama City, Tokyo, intended to maximize the use of artificial intelligence in running city affairs. He was running his campaign （竞选运动） as "AI Mayor". Basically, he was suggesting replacing human public officials with AI and having them collect city data and create fair and balanced policies that will benefit everyone.

    "For the first time in the world, AI will run in an election," human candidate Michihito Matsuda announced on Twitter. "Artificial Intelligence will change Toma City. With the birth of an AI Mayor, we will conduct balanced politics."

    The AI Mayor was campaigning very much like its human competitors. Posters were shown all over Tama City and campaign trucks were blaring out（大声鸣响）promises of an AI utopia （乌托邦）and asking for support.

    Some people called Michihito Matsuda's campaign a stunt （噱头）, as a human would still be the one legally in charge. However, others said that they were excited about the future of AI running things in the background, adding that it had to be a better choice.
