    New York's iconic, blue-green statue of liberty wasn't always green. When the statue was gifted to the US from France in 1885, she was actually a shiny copper color. A new video reveals the chemical reactions involving oxygen and even air pollution that led to her color change from copper to liberty green. The statue of liberty was a gift from France to the US as a way of commemorating the US's fight for independence, as well as their own aspiration for democracy.

    A video, published by the American Chemical Society, explains that the 305-foot (93 meter) statue was built over nine years in sections of copper skin on top of an iron skeleton.

    In her first few decades in the Big Apple, the statue slowly turned from that shiny copper color to a dull brown and the, finally, to the blue-green, or as they'd say back in France, 'verdigris' we see today,' said the video's narrator.

When it changed color, some officials suggested restoring her back to her original color, but after the public protested against this decision, she was left the way she is. The statue's color change was as a result of oxidation reactions between copper and the air. But it was more than one reaction - the color change is due to about 30 years worth of different reactions leading to a mixture of greenish minerals.

    Oxidation reactions happen when an atom loses an electron to another atom.

    In the case of the statue of liberty, her color change was bound to happen due to oxygen in the atmosphere that is 'hungry' for electrons. On top of this, elements of New York City's polluted air added to the color change too.

The first chemical reaction of the color change involved copper giving up electrons to electron-hungry oxygen in the atmosphere. This led to a mineral called cuprite - which is pinkish red.

    Then, cuprite loses even more electrons to oxygen, forming a new mineral（矿物质） called tenorite, which is blackish in color. The black color of tenorite explains why the statue got darker over time, forming a dark brown color.

    Then, further chemical reactions occurred when sulfur（硫） in the atmosphere reacts with oxygen to form sulfur dioxide. Sulfur comes from natural processes such as volcanic eruptions, but also from man-made emissions from boats, cars, airplanes and factories. When sulfur dioxide in the atmosphere reacts with water, it produces sulfuric acid. Sulfuric acid forms green minerals with copper oxides, so the sulfuric acid in the atmosphere made the state green over time.

    Added to that, chloride from the sea spray surrounding Ellis Island where the statue is located made the statue even greener.

    The statue stayed this way for over 100 years because the exposed copper is now oxidized and stable, but the statue wouldn't be the same anywhere else.

    On August 25, Hurricane Harvey made landfall in Southern Texas. The storm lasted for days, pouring almost 52 inches of rain. The downpour has caused widespread flooding, forcing more than 32,000 people into shelters and damaging the city's water supply system.

    The only silver lining is that disasters like these seemed to unite people. While the number of organizations and individuals that have gone all out to assist the victims is too many to list, here are some highlights of the outpouring of support that has made headlines this past week.

    A week ago, NFI player JJ Watt set up a website with a goal to raise $200,000. Soon he has collected over $18 million, and the donations keep pouring in. The thrilled football star wants to ensure the money is used where needed, saying, “We're trying to make sure it goes directly to the people. So our first wave of operation is we'll have nine semi-trucks going out there and I will go straight into the communities and hand stuff out there.”

    Ordinary individuals are not shying away from helping either. Jim McIngvale, the owner of a furniture store, turned his two 100,000-square-foot warehouse into shelters. When asked if he was concerned about the furniture that was being used by those living there, he responded, “These people are nice. They're taking care of the furniture. Furniture's made to be sat on, slept on or laid on. It's just a product.”

    There are also many unsung heroes that are putting their lives at risk to help others. After discovering an elderly man trapped inside his truck, local people made a human chain through the dangerous water to drag him to safety.

    While there is not much anyone could have done to prevent the loss, people across the US are doing everything they can to help its people recover.

    Do you believe in the power of music? If you're like most kids these days, you probably have an electronic device loaded with hundreds or even thousands of your favorite songs. At any moment in time, you can fill your headphones with the sounds of a particular song that suits your mood at that exact time.

    Are you getting ready for a big soccer match or do you need to get excited? Maybe some hip hop with a strong beat will do the trick! Besides, you might be ready to study for a big exam the next day. To calm your nerves and help you concentrate, a little bit of Mozart might make memorization more manageable.

    But is there any scientific evidence of these effects that music seems to have? You bet there is! Scientists have long recognized the power of music. Over the years, many studies have been conducted to examine in greater depth the nature and extent of the effects music has on people.

    For example, scientists at the University of Missouri have found that listening to music can have a positive effect on your mood. Their research gives scientific credibility(可信性) to the behavior that many people have already experienced on their own: listening to upbeat music can brighten your day and boost your mood.

    Other studies have shown that upbeat music isn't the only type of music that can be helpful, however. When people are sad or have suffered a personal loss, sad music can be helpful because people identify with the tone and lyrias(歌词) of the music. Likewise, people under a lot of stress or experiencing upsetting situations can benefit from listening to angry music. Although angry music might not help you if you're in a normal mood, its tone can benefit you when you are dealing with stressful and upsetting situations.

    In a career that lasted more than half a century, Tom Wolfe wrote fiction and nonfiction best-sellers including The Electric Kool-Aid Acid Test and The Bonfire of the Vanities. Along the way, he created a new type of journalism and coined phrases that became part of the American vocabulary.

    Wolfe began working as a newspaper reporter, first for The Washington Post, then the New York Herald Tribune. He developed a literary style in nonfiction that became known as the "New Journalism." "I've always agreed on a theoretical level that the techniques for fiction and nonfiction are interchangeable," he said. "The things that work in nonfiction would work in fiction, and vice versa."

    "When Tom Wolfe's voice broke into the world of nonfiction, it was a time when a lot of writers, and a lot of artists in general, were turning inwards," says Lev Grossman, book critic for Time magazine. "Wolfe didn't do that. Wolfe turned outwards. He was a guy who was interested in other people." Wolfe was interested in how they thought, how they did things and how the things they did affected the world around them.

    In 1979, Wolfe published The Right Stuff, an account of the military test pilots who became America's first astronauts. Four years later, the book was adapted as a feature film. "The Right Stuff was the book for me," says Grossman. "It reminded me, in case I'd forgotten, that the world is an incredible place."

    In The Right Stuff, Wolfe popularized the phrase "pushing the envelope." In a New York magazine article, Wolfe described the 1970s as "The 'Me' Decade." Grossman says these phrases became part of the American idiom because they were accurate.

    "He was an enormously forceful observer, and he was not afraid of making strong claims about what was happening in reality," Grossman says. "He did it well and people heard him. And they repeated what he said because he was right." All those words started a revolution in nonfiction that is still going on.

At the beginning of the century there was a big farm called Hollywood Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places in the world. From the 1910s to the 1950s Hollywood was the film center of the world. Every family knew the names of its film stars — Charlie Chaplin, Grela Garbo, Bergman and hundreds more.

The reason why people went to Hollywood to make films was the sun. At first people made films in New York on the east coast of the United States. But then they heard about Los Angeles where there are 350 days of sun every year. As they made all the films by sunlight, the west coast was a much better place to work. Also near Hollywood you can find mountains and sea and desert. They did not have to travel far to make any kind of film.

When TV became popular, Hollywood started making films for television. Then in the 1970s they discovered people still went to the cinema to see big expensive films. After twenty years they are still making films in Hollywood and people watch them all over the world.
