New York Time—A gunman killed eight people at a mall in Omaha this afternoon and then killed himself, setting off panic among holiday shoppers, the police said.

    "The person who we believe to be the shooter has died from self-inflicted gunshot wounds," Sergeant Teresa Negron of the Omaha Police Department said at televised news." We have been able to clear the mall," she said." We don't believe we have any other shooters." The police said that at least five other people had been injured in the shootings.

    She did not give the shooter's identity." We are still conducting the investigation," Sergeant Negron said, adding that the city's mayor, who was out of town, was on his way back to Omaha.

    She said the police received a 911 call from someone inside the Westroads Mall on the west side of Omaha, and shots could be heard in the background. The first police officers arrived at the mall six minutes after the first call, she said but by then the shootings were over.

    It is reported that the gunman left a suicide note that was found at his home by relatives. A law enforcement official who spoke on condition of anonymity（匿名）said the note indicated that the gunman wanted to "go out in style."

    The shootings broke the usually ordinary routine of holiday shopping. The gunman was said by some witnesses to have fired about 20 shots into a crowd. Some customers and workers ran screaming from the mall, while others dived into dressing rooms to hide from the shooter.

    Shoppers and store workers were trapped inside the mall, which has roughly 135 stores. Others streamed out of mall exits with their hands raised. President Bush was in Omaha this morning to deliver a speech, but he had left the city by the time the shootings took place.

The practice of students endlessly copying letters and sentences from a blackboard is a thing of the past. With the coming of new technologies like computers and smartphone, writing by hand has become something of nostalgic (怀旧的)skill. However, while today's educators are using more and more technology in their teaching, many believe basic handwriting skills are still necessary for students to be successful—both in school and in life.

    Virginia Berninger, professor of educational psychology at the University of Washington, says it's important to continue teaching handwriting and help children acquire the skill of writing by hand.

Berninger and her colleagues conducted a study that looked at the ability of students to complete various writing tasks—both on a computer and by hand. The study, published in 2009, found that when writing with a pen and paper, participants wrote longer essays and more complete sentences and had a faster word production rate.

    In a more recent study, Berninger looked at what role spelling plays in a student's writing skills and found that how well children spell is tied to know well they can write. “Spelling makes some of the thinking parts of the brain active which helps us access our vocabulary, word meaning and concepts. It is allowing our written language to connect with ideas.” Berninger said.

    Spelling helps students translate ideas into words in their mind first and then to transcribe(转换) “those words in the mind written symbols on paper or keyboard and screen,” the study said. Seeing the words in the “mind's eye” helps children not only to turn their ideas into words, says Berninger, but also to spot(发现) spelling mistakes when they write the words down and to correct then over time.

     “In our computer age, some people believe that we don't have to teach spelling because we have spell checks,” she said. “But until a child has a functional spelling ability of about a fifth grade level, they won't have the knowledge to choose the correct spelling among the options given by the computer.”

    Australia is a developed country and the future of its solar industry is looking bright after a record 3.5m panels (嵌板) were installed on rooftops last year, giving the equal output of a medium-sized coal-fired power station. The record 1,057 MW of capacity (生产能力) in small-scale systems installed across the country broke the previous record set in 2012, figures from the Clean Energy Regulator showed on Tuesday.

    Australia's solar power prosperity could almost double capacity in a year. The data also revealed that the average system size has also doubled since then from three to six kilowatts as average prices continued to fall. A fully installed 5KW system costs an average of $5,930 in Australia, according to the energy broker Solarchoice. net. au. Its records show that the price has roughly halved in many capital cities since 2012.

    The regulator's executive general manager, Mark Williamson, said there was increasing interest in renewals as a way to take control of electricity bills. But more importantly, he said it was also good news for reducing carbon emissions.

    “We are seeing a wide cross-section of Australians-households, community centers, schools, and small businesses-receiving rewards under the small-scale renewable energy scheme,” Williamson said. “Our data shows consumers are embracing renewable energy to take control of their electricity bills.”

    In 2017, there was a 41% increase in installing renewable energy capacity across all states and territories compared to 2016. Queensland led the way with installed capacity at 295MW, with the Australian Capital Territory taking top place for the biggest annual increase by 57%. “The data collected by the Clean Energy Regulator in 2017 reflects the industry is going from strength to strength. It looks like 2018 will be another big year for the solar industry.”

    The total of installed capacity for last year is expected to rise to 1,070MW when all the data is collected. A large coal-fired power station such as Loyd Yang A in Victoria's Latrobe Valley has a capacity of 2,200MW.

    Here's a list of books I'm looking forward to this fall season. Not all of them will rise to the level of the advertisement, but it's an abundant crop.

    "Farm to table" is the name of a movement that encourages people to eat locally grown food. The farm-to-table idea has become more popular in recent years. But there is also a movement that brings "table to farm". Its purpose is to connect people to the land and to honor local farmers by creating a sort of restaurant without walls.

    Its founder, Jim Denevan, got the idea for this kind of "culinary adventure (美食探险)", as he called it, ten years ago. He recently prepared tables for more than a hundred people at Briars Farm in Virginia. He and his eight-member team arrived the night before. Chefs (厨师) from a local  restaurant prepared the dinner.

    Jim Denevan's brother is a farmer and he himself is a chef. He thought that the idea of a meal served right on the farm made sense, though not everyone agreed.

    "But I wanted to make the idea work, so I decided to cross the country, " said Denevan. "I went all the way across the United States and set the table on farms, ranches (大牧场) and beaches, and all the places where food came from. "

    "This kind of event connects us with a lot of enthusiastic people, people that we can form relationships with, " said Matt Szechenyi, who operates Briars Farm.

    The tour of the farm ends at the dinner table. The meats in the meal come from Matt Szechenyi's farm. The vegetables come from nearby farms. Guests and local farmers sit together.

    Annoica Ingram came with a friend. "The food is wonderful. I appreciate their hard work. I see everything they have to do to take care of the animals and make sure they are well-cared-for. Without them, I think, we'll have big problems, " she said.
