The Verizon Innovative App Challenge gives kids a chance to create apps that can solve problems in their community.

    Do you want to make a difference in your community? The Verizon Innovative App Challenge can get you started. The first step is to think of a problem in your community. The next step is to create an app that can solve the problem.

    Groups of five to seven students in middle school or high school, led by a teacher, can enter the contest. First, teams compete on a local level. Teams that make it to the next round receive $5,000 for their schools. Finalists present their app ideas to judges in a live webinar (网络研讨会)．

    Next, the judges pick national winners. The top eight teams receive an additional $15,000 for their schools, and each team member receives a Samsung tablet. Plus, the winning teams get the chance to bring their app to life.

    A group of six girls from Los Fresnos, Texas, won the second annual Verizon Innovative App Challenge. They came up with the Hello Navi app concept, short for “hello navigation”. The app was designed to help visually­impaired (视力受损的) students navigate their school by using an internal compass and voice­over technology. Read more about the team in September 19, 2016 issue of TIME For Kids: Edition 3－4.

    Do you have an app idea that could help solve a local issue? The deadline to register is November 24, 2016. Find more information and register your team at www. verizonfoundation. org/appchallenge.

    Here are some tips from the Verizon Foundation to get you started：

•Get your team together for a brainstorming meeting. Write out all the ideas that come to mind.

• Don't ignore challenges. Think of the problems that exist in your community.

•Ask family, friends, and people in your community to share their thoughts about problems that they want to see solved.

    Getting rid of dirt(灰尘), in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.

    In the early 16th century, people thought that dirt on the skin was a way to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let illnesses in. A particular danger was thought to lie in public baths. By 1538, the French king bad closed the bath houses in his kingdom. So did the king of England in 1546. Thus it began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

    Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War ll. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

    Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warm(警告)their children of touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

    Looking almost as fresh as the day it was bought, this McDonald's Happy Meal is in fact six months old. Photographed every day for the past six months by Manhattan artist Sally Davies, the kids meal of fries and burger hasn't any signs of mould(霉菌) or decay(腐烂).

    Sally put the Happy Meal on a shelf in her apartment and watched it with increasing shock. Even her dogs stopped trying to steal a free tasty snack.

    “I bought the meal on April 10 this year and brought home to see how it changed,” she said. “I chose McDonald's because it was nearest to my house, but the project could have been about any other fast food. The first thing that shocked me on the second day of the experiment was that it no longer gave out any smell. And my dogs stopped circling the shelf.”

    Sally expected the food to go mouldy after a few days. In fact, Mrs. Davies' surprise turned to shock as the food still had not shown any signs of decay after two weeks. “It was then that I realized that something strange might be going on with this food that I had bought,” she explained. “The appearance of the food did not change as the weeks turned to months. And now, at six months old, the food is plastic to touch. The only change that I can see is that it has become as hard as a rock.”

    The experiment has brought her amusement rather than fear. “Maybe I would be frightened at seeing this if I were a meat eater.” she said.

    In 2007, the editors of the Oxford Junior English Dictionary, convinced that their reference work “needed to reflect the consensus experience of modern-day childhood.”banned a group of old terms used less today describing the natural world. They inserted newer and supposedly more useful words describing the digital fields that young people in habit today.

    Thus they say goodbye to “acorn”, but say hello to “attachment”. “Beech” and “bluebell” come out of the dictionary. While “blog” and “broadband” come into it. And they say farewell to “catkin” and “cowslip” because here come “celebrity” and “chat room”.

    It's possible, of course, that those Oxford editors had a good reason for their vocabular cleansing. Perhaps they had read the Cambridge University study revealing that most young children can identify Pokémon(神奇宝贝)species far more easily than they can name real-life sparrows.

    But is this simply another fight in the language war, an ongoing battle between people? Some people argue that a dictionary should model how language works best, while some people insist that it should capture how language works now.

In Britain, some citizens felt justified in fighting back against the decision of the Oxford editors. The protest of the thinning of the word herd almost immediately attracted more than200, 000 signatures.

    Susie Dent, author of Modern Tribes：The Secret Languages of Britain, is doing everything in her power to guarantee “the old markers of time”. “Fortnight”(fourteen nights, or two weeks)is among her cherished favorites.

    Thanks to them, I can now show off my knowledge that a “snollygoster” is a “shrewd person, especially a politician”.

    Nowadays six Amazon Scout delivery robots rolled out in a pilot program in Snohomish County, Wash. The robots carry meals, groceries and packages to homes and offices in this region just north of Seattle. They have appeared on the sidewalks of London, Beijing and other cities and communities worldwide. These machines must overcome pedestrian legs, naughty dogs and broken pavement, which raises some questions.

    These services are gaining attraction as a growing number of city residents expect immediate or scheduled delivery for just about everything. Between 2017 and 2018 online retail sales in the U.S. increased by 16 percent. On the final step of all these deliveries, called the last mile, humans on bicycles, motorized scooters (电动车) or large delivery trucks typically deliver packages. All the vehicles compete for space on busy urban streets. "Deliveries are trending upwards in all crowded city centers, and if city and state leaders don't start thinking about creative solutions like robot deliveries, we can expect even worse traffic jams," says Paul Mackie, director of a transportation policy research center in Arlington.

    A study by this center found 73 percent of delivery vehicles in Arlington were parked outside of authorized areas, often blocking bike lanes and crosswalks. By moving the last step of deliveries from the road to the sidewalk, cities could reduce traffic jams and solve the parking problem entirely, Mackie says.

    Companies such as Amazon are not developing this delivery technology simply to clear up urban traffic. Self-driving vehicles and sidewalk robots could cut down last-mile delivery costs in cities by as much as 40 percent, according to a 2018 report by a consultancy firm. A delivery robot can cost thousands of dollars to manufacture, and most currently require human management and conservation. But in the long run companies that use autonomous delivery vehicles in the next several years could end up saving billions of dollars, the report stated.
