To most people, noise pollution is a jet flying over their head. For one Spanish woman, it is a neighbor playing the piano. The woman has taken her neighbor to court. Now she wants to send her neighbor to prison for over seven years on the charges of psychological damage and noise pollution.

    In a country known for its noisiness, the case has raised eyebrows. Neighbors often complain  about street noise in Spain, but people seeking prison time for someone practicing the piano is unheard of. At the trial, Sonia Bosom says she has been suffering noise pollution up to now due to the practice sessions of Laia Martin, who lives below her. Martin, 27, didn't admit that she played at home that often, saying she took regular classes in other towns and mostly practiced at home on the weekends.

    On the first day of the trial, the newspaper reported that Bosom told the court she now hated pianos so much that she couldn't even stand seeing them in a film. Bosom says years of hearing Constant playing has caused her “psychological injury”. Medical reports show she has suffered from a variety of problems, including insomnia (失眠), anxiety, and panic attacks.

    She says tests by local authorities have found that the sound levels made by the piano are up to 10 decibels （分贝）higher than the limit. City authorities have asked the family several times to either stop the piano playing or soundproof (隔音) the room. The family told the court that they carried out soundproofing work twice but the complaints continued.

    The court hasn't made a final decision. A spokeswoman says the trial will end before May.

Model Railroading

    Would you like to know a fun way to learn about math? Well, you can do that with model railroading. Yes, it's true. You can learn about many school topics without using a school book. Besides that, there are many other benefits that model railroading brings us as well. In this article, we will discuss just a few of those benefits of model railroading.

Patience and problem solving skills

    When you build a model railroad, you have to plan your railroad out. You have to decide where the tracks (轨道) will go, where to put buildings, where to put streets and any other things you would like to add to your model railroad. Also, you have to think about any problems you may have with the design you choose. How will you make railroad crossings? How will you design hills, mountains, and rivers? Deciding on what to do with your model railroad takes a lot of thought and patience, but it is not as difficult as you may think.

Building skills

    With model railroading, you learn how to put together plastic models of buildings. Also, you can learn how to build a table for your design, or make scenery for the geography of your design. Your model railroad runs on electricity, so you learn about electronics as well. These are skills that not only help you build a model railroad; these skills will help you all throughout life.

Fun for family and friends

    Different from many video games, model railroading is a social hobby that lets you communicate with family and friends. This is because you have to communicate with family and friends as you build and run your model railroad. By spending time with the people in your life you love and care about, you learn to become closer and care more for each other. This is one of the best parts of model railroading as a hobby. Of course, the best part about model railroading is running the trains. Watching the trains run around the track and make all the sounds and do all the things that real trains do gives people hours of enjoyment. Also, there is great satisfaction in the fact that you, your family, and your friends built the model railroad.

    I hope you can learn to enjoy model railroading and experience all the benefits you just read about and many others. Happy railroading!

    Rachel Carson (1907-1964) is a writer, biologist, and environmentalist. As a trained scientist and a great writer, Rachel Carson did much to shape people's attitudes toward the natural world. Born in Springdale, Pennsylvania, she shared from childhood her mother's love of books and feeling for the beauty and mystery of nature. At Pennsylvania College for Women, she first majored in English, but later learned biology. The imagination of a creative writer with a scientific lobe for fact made her books successful. After graduating with honors, she won a scholarship to Johns Hopkins University, where she earned an A.M. in zoology.

    When her father died suddenly in 1935, she took a job as an aquatic(水生的) biologist. An article for the Atlantic Monthly led to her first book, Under the Sea Wind (1941). During World War II she wrote a series of booklets on wildlife refuges(收容所). Meanwhile she had been working on a book that would make her known throughout the world. Published in 1951, The Sea Around Us became an immediate best-seller, won many honors and literary awards, and was translated into thirty-two languages. After earning enough money, she could devote full time to writing. Her next book, The Edge of the Sea (1955), was also a success.

    Rachel Carson's last book, Silent Spring (1962), became one of the most famous books of the last half of the twentieth century. Ever since the end of World War II, when the insecticide (杀虫剂) DDT came on the market, she had been worried about the dangers in the uncontrolled use of the poisons: their effect on wildlife, on human life, and on the environment. She decided to speak out. The result was a book showing how modern society has been poisoning the earth on a worldwide scale. "A few thousand words from her," wrote a newspaper editor, "and the world took a new direction."

    One of the most expensive parts of flying is the cost of gas, not to mention the environmental effect it brings. An Israeli startup called Eviation Aircraft hopes to solve the problems. They displayed the world's first all-electric passenger airplane this week at the Paris Air Show.

    The lightweight plane­playfully called Alice­will be able to fly about 600 miles between charges. So it will focus on transportation between cities. It seats nine passengers and two crew members. A typical flight should cost a customer about $200.

    "The fact that we' re building an electric plane from scratch instead of just refitting an existing plane with a battery means that we can design our aircraft to be more effective and efficient than present planes," said Eviation co-founder Omer Bar Yohay. He predicts that per seat, per mile, the cost would be equal to that of a taxi or train.

    The demand for electrically powered aircraft is projected to reach hundreds of planes per year within the next decade. The change from gas to electric in power is expected to save millions of dollars in fuel costs, not to mention the environmental benefits including significant reduction of air pollution and noise levels.

    When it comes to the new possibilities, Yosef Abramowitz, an energy industry expert, said, "In modern life, it is important to fight climate change and now we have a path to do so in flying." Abramowitz, a tireless advocate for solar power, added, "The batteries will hopefully be charged with solar energy too."

    To help further save fuel costs, the designers have also invented a "taxibot" that drags planes from the passenger gate to the runway, so the planes needn't run their engines.

    After appearing at the Paris Air Show, the Alice will travel to the U.S. for further tests. It is expected that the first commercial flights will take off in 2022.

    "I think for the first time in a very, very long time, we can look at flight again and talk about the next revolution," Bar Yohay said.

Imagine reading a story titled "Pursuing Success." That would be an inspiring story, wouldn't it? Maybe—but maybe not. It might well be the story of someone whose never-ending chase for more and more success leaves them unsatisfied and incapable of happiness.

Though it isn't a conventional medical addiction, for many people success has addictive properties. Obviously, success goes with praise. To a certain extent, praise stimulates the neurotransmitter dopamine (神经递质多巴胺), which contributes to all addictive behaviors.

The desire for success may be born to human nature, but specialness doesn't come cheap. Success is tough work, and it requires bearing the cost of losing. In the 1980s, the physician Robert Goldman famously found that more than half of ambitious athletes would be willing to take a drug that would kill them in five years in exchange for winning every competition they entered.

Unfortunately, success is endless. The goal can't be satisfied; most people never feel "successful" enough. The high only lasts a day or two, and then it's on to the next goal. Psychologists call this the hedonic treadmill (快乐跑步机现象), in which satisfaction wears off almost immediately and we must run on to the next reward to avoid the feeling of falling behind.

People should get off the treadmill. But quitting isn't easy for addicts. For people hooked on substances, withdrawal can be a painful experience, both physically and psychologically, research finds that depression and anxiety are common among outstanding athletes after their careers end. Olympic athletes, in particular, suffer from the" post-Olympic blues."

Just like wine, success in and of itself is not a bad thing. Both can bring fun and sweetness to life. But both become bossy when they are a substitute for — instead of a complement (补充物)to — the relationships and love that should be at the center of our lives.
