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.

    Leonardo da Vinci, one of the greatest thinkers in the world, began his career as an artist. Very little is known about Leonardo's early life. He was born in 1452 in the town of Vinci. As a boy, Leonardo showed a great interest in drawing, sculpting and observing nature.

    However, because Leonardo was born to parents who were not married to each other, he was barred from some studies and professions. He trained as an artist after moving to Florence with his father in the 1460s. It was an exciting time to be in Florence, one of the cultural capitals of Europe. Leonardo trained with one of the city's very successful artists, Andrea del Verrocchio. He was a painter, sculptor and gold worker. Verrocchio told his students that they needed to understand the body's bones and muscles when drawing people.

    Leonardo took the teacher's advice very seriously. He spent several periods of his life studying the human body by taking apart and examining dead bodies. While training as an artist, Leonardo also learned about and improved on relatively new painting methods at the time. One was the use of perspective(透视) to show depth. A method called “sfumato” helped to create a cloudy effect to suggest distance. “Chiaroscuro” is a method using light and shade as a painterly effect.

    Leonardo's first known portrait now hangs in the National Gallery in Washington, D. C. He made this painting of a young woman named Ginevra de' Benci around 1474. The woman has a pale face with dark hair. In the distance, Leonardo painted the Italian countryside.

    He soon received attention for his extraordinary artistic skills. Around 1475 he was asked to draw an angel in Verrocchio's painting “Baptism of Christ.” One story says that when Verrocchio saw Leonardo's addition to the painting, he was so amazed by his student's skill that he said he would never paint again.

    Group exercise is one of the most effective ways to improve physical fitness and sustain a healthy lifestyle.Group exercise is challenging, yet fun and empowering! Of course everyone knows that exercise is good for the body.However, studies have shown that when exercise is performed in groups, it's not only great for improving physical health but for psychological health. It's an opportunity to be social, release endorphins  , and improve your strength. Additionally, group exercise creates a community feel and the shared common goal motivates participants to work hard. The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone.

    Another beneficial aspect of group exercise is the informational support participants receive from the instructor.Many people fear the gym because they feel lost and don't want to embarrass themselves. If you feel you can relate, then group training is an even better option for you. It's a great opportunity to learn more about fitness through the clear instruction and supervision of a fitness instructor. If you're tired of wandering around the gym wasting time and becoming bored, !you can attend an upbeat group fitness class that'll keep your workout on track. Don't let fitness frighten you!

    If you're serious about wanting to live a healthy lifestyle, it's extremely important to surround yourself with people who'll provide you with the proper emotional support. I wouldn't scold anyone for deciding to party on weekends and in turn I wouldn't expect anyone to give offence to me for focusing on my health. Surround yourself with people who uplift, encourage and understand you! Make fitness even more fun by trying something new or any group fitness class, with a friend. Plan to go for a jog together. Then try a fun healthy restaurant or fresh juice bar! Fitness can be both fun and social!

    Surrounding yourself with people who'll provide you with respect support can be very beneficial while working towards reaching health and fitness goals. First, decide to do it for yourself and work towards staying positive. Then make sure the people you surround yourself with are supportive. Don't let negativity ruin your motivation.

    Most American students go to traditional public schools. There are about 88,000 public schools all over the US. Some students attend about 3,000 independent public schools called charter schools.

    Charter schools are self­governing. Private companies operate some charter schools. They are similar in some ways to traditional public schools. They receive tax just as other public schools do. Charter schools must prove to local or state governments that their students are learning. These governments provide the schools with the agreement called a charter that permits them to operate.

    Charter schools are different because they do not have to obey most laws governing traditional public schools. Local, state or federal governments cannot tell them what to teach. Each school can choose its own goals and decide the ways it wants to reach them. Class size is usually smaller than in traditional public schools.

    Governments strongly support charter schools as a way to re­organize public schools that are failing to educate students. But some education agencies and unions oppose charter schools. One teachers' union has just made public the results of the first national study comparing the progress of students in traditional schools and charter schools.

    The American Federation of Teachers criticized the government's delay in releasing the results of the study, which is called the National Assessment of Educational Progress. Union education experts say the study shows that charter school students performed worse in math and reading tests than students in regular public schools.

    Some experts say the study is not a fair look at charter schools because students in those schools have more problems than students in traditional schools. Other education experts say the study results should make charter school officials demand more student progress.

    The end of the school year is in sight — Christmas cards, candy canes and of course, end of year reports.

    While most parents welcome an assessment of their kids' performance, they do not expect their own input to be evaluated. But a school in the UK is changing that. As well as assessing their students, they are dishing out grades to mums and dads. Parents that are really involved in their kid's education are rewarded with an A, and parents that haven't done their bit get a disappointing D.

    The school, Greasley Beauvale Primary in Nottinghamshire, uses criteria such as whether mums and dads have attended school events such as plays and parent-teacher conferences to decide on the grade. The school's principal, Donna Chambers, said that the scheme (方案)had been well received.

    “There were some critics, but my response was 'well, it can't do any harm'. Between 15 percent and 20 percent of parents started out in the lower categories but now that has been reduced to just two percent,” she explained.

    Chambers hopes that the scheme will help motivate parental involvement. “The system is important because you have got to get the parents on board from day one. That one hour initial conversation saying they could improve will pay dividends for the rest of that child's academic life”, she said.

    But while the scheme may be well-intentioned, it is likely to be connected with parent shaming. There are lots of reasons why some mums and dads might not be involved in school activities such as work commitments, looking after younger children or caring for elderly relatives.

    And of course, being involved in your kid's education doesn't begin and end at school. There is a lot that goes on behind the scenes from helping with homework to keeping uniforms freshly laundered. And what about all the parents who stayed up sewing special costumes at the last minute? Surely that earns a gold star instead of a grade!

    Ideas of making the first weeks of high school easy

    Frank. aged 21

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!

    Sharon. aged 22

    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to do.

    Eddie. aged 20

    When I started high school, I was really nervous too, especially since I had been home schooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    David. aged 19

    I'm not going to lie. The first day is kind of frightening. But you'll get used to it. Don't be afraid of anyone; upperclassmen will pick on(J E )you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.
