     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!  

    Here is an astonishing and significant fact：Mental work alone can't make us tire. It sounds absurd．But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all!

    If we took a drop of blood from a day laborer, we would find it full of fatigue toxins (霉素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.

    So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?

    Some scientists declare that most of our fatigue comes from our mental and emotional (情绪的)attitudes. One of England's most outstanding scientists, J. A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare. ”Dr. Brill, a famous American scientist, goes even further, He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”

    What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated— those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.

    Thousands of taxi drivers in Shenyang, Liaoning province, reportedly blocked streets with their vehicles on Sunday in protest against unlicensed vehicles using taxi-hiring apps and apps-based car rental companies providing passenger services, including high-end cars. Although the drivers also complained about the withdrawal of the fuel subsidy (补贴)by the government, their main complaint was the loss of business because of the rising number of Internet-based car services companies.

    On Wednesday, news reports came that Beijing transport authorities will take measures to stop the illegal “taxi business” of private cars through the newly rising Internet apps, following the footsteps of Shenyang and Nanjing.

    It is not yet clear how the Shenyang city government will handle the issue and whether it will declare the services offered by market leaders such as Didi Dache, a taxi-hiring app provider backed by Tencent Holdings, and Kuaidi Dache illegal. But Shanghai transport regulators (交通管理结构)have set a rule, by banning Didi Zhuanche, or car services offered by Didi Dache in December.

    Such regulations will cause a setback to the car-hiring companies and investors that are waiting to cash in on the potentially booming business. Just last month, Didi Dache got $700 million in funding from global investors, including Singapore state investment company Temasek Holdings, Russian investment company DST Global and Tencent. Besides, the market is uncertain that Kuaidi Dache is about to finalize its latest round of funding after getting $800 million from global investors.

    Regulatory uncertainties, however, could cast a shadow on the future of the Internet-based car-hiring services, which have become popular in most of China's big cities. To be fair, these companies' business model is anything but bad. For example, Didi Zhuanche works side by side with established car rental companies to provide high-end car service mainly for businesspeople through the Internet and mobile phone apps.

    Every link in this business model chain has legal companies and services. Hence, it is hard to define it as illegal and ban it.

    Banker Chip Paillex had never planted so much until he moved to the countryside in Pittstown, New Jersey, seven years ago. Surrounded by working farms, he quickly became interested in the grow-it-yourself idea and rented a piece of 30-by-30-foot land. He planted tomatoes, eggplants and other vegetable—enough to feed his family of four for the summer. He ended up with so much produce; he couldn't give it away. He found a local food factory and donated 120 pounds of fresh vegetables.

    The following year, with a handful of volunteers and a memorable name—America's Grow-a-Row, Paillex harvested 1, 500 pounds of fresh vegetables, all of which he donated to area food banks--places that give food to poor people. Soon Paillex had a hundred volunteers and needed more land. He visited Meredith and Jeremy Compton, who farm Peaceful Valley Orchards in Pittstown. Could he work their land?

    “I guess we were feeling honored, " says Meredith. Not only do the Comptons welcome Grow-a-Row volunteers, they also work on the land.

    What began with a few empty fields has turned into a large local farm. This year, Grow-a-Row will deliver about 250, 000 pounds of fresh produce to food banks. Their secret for getting all of this done? Family power. " Each week, a couple of families 'own' the garden, " says Paillex." They water, pick, and deliver, and then hand it off on Sunday night to the next group of families."

    Paillex also welcomed local school kids. On a Friday morning in May, some kids worked on a field. "We' re growing food, " one fifth grader said proudly.

    "The program shows kids that there are people in need, " says Paillex. “When these kids become tomorrow's leaders, they'll be much more likely to encourage their co-workers or employees to get involved in something like this. “

    "Chip makes people want to help, " says Colleen Duerr, a mother of two. "And families love this. Chip has given us a way to raise our kids with a giving heart. "

    Driverless technology will soon enter another major global industry: shipping. Several companies recently announced plans to start self-sailing ships to improve safety and efficiency（效率）.

    One of them is Norwegian chemical company Yara International. Yara has designed to build an autonomous ship expected to start next year. The ship is fully electric to reduce air pollution. It is designed to carry containers normally transported by truck. This means the ship will also improve road safety by replacing about 40,000 truck trips a year.

    Yara plans to operate the ships by remote control beginning sometime next year. By 2020, the ships should be loading and sailing themselves. Another company focusing on self-sailing ships is the world's largest mining company, Australia's BHP Billiton. The company's Vice President of Freight, Rashpal Bhatti, recently spoke about the technology. He said, “I believe automation（自动化）will be one of the biggest changes for shipping in the future.” Autonomous ships offer important chances to improve safety and provide better efficiency results to the marine supply chain. He added that self-sailing ships could become a reality within the next decade.

    Rolls-Royce, the British automobile and engine manufacturer, is also developing unmanned shipping technologies. Oskar Levander is the company's head of marine operations. He told a conference last year, “This is happening. It's not if, it's when.” Several shipping companies have invested hundreds of millions of dollars to develop self-sailing ships expected to be used by 2025. These ships will be equipped with technology to collect weather and sea data. They will then use the data to plan out the safest, shortest and most fuel-efficient route.

    In the near future, IoT (Internet of Things) will drive huge innovation (革新) in the way our food is grown. Plants will have a "voice", not a human voice, but a voice based on data that can tell people, computers, and machines when, for example, they are thirsty, or need more sun, medicine, etc.

    Take vertical (垂直的) farms, for example. Farming is moving indoors where the growth of plants can be monitored and controlled. The facilities are built vertically, so growing areas can be put in piles. This greatly reduces the amount of land needed for farming.

    From an IoT point of view, vertical farms are connected in two ways. First, small sensors (传感器) in the soil or connected to plants tell a control system exactly how much light, water, and nutrients are needed to grow the healthiest crops. Sensors will also tell vertical farmers when crops are nearing their peak for harvesting at just the right time to make sure it's still fresh when it reaches its final destination.

    Second, vertical farms will be connected to other networks and information systems, including databases that track local demand. For example, local restaurants may input when they need fresh food supplies. And vertical farmers could get that information so they know which crops to grow in what quantities. This type of IoT system would have been unimaginable a generation ago.

    Today, vertical farms are being experimented. Yet, the numbers point to a bright future for the industry, especially as the world's population continues to grow. For example, Green Sense Farms in Chicago is able to harvest crops 26 times a year using 85 percent less energy, one-tenth the water, and no pesticides. A side benefit of lower energy use is lower CO₂ output of two tons per month, with the added benefit of creating 46 pounds of oxygen every day.
