    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.

    Today, I had the good fortune to join the students from East Silver Spring Elementary School in Maryland as they walked and biked to school in celebration of International Walk to School Day. I want to thank Principal Morrow and the entire ESS community for welcoming me so enthusiastically.

    Walk to School Day is a great opportunity for me to spend time with parents, kids, and teachers and to present our Safe Routes to School program and the First Lady Michelle Obama's Let's Move initiative(倡议).

    As a father, grandfather and former schoolteacher, I know how important it is that we provide students with safe choice to get to school while promoting exercise and healthy lifestyles. That's why I've embraced the Safe Routes to School program so wholeheartedly since I became Secretary of Transportation.

    You know, we're looking at an increasingly sedentary(久坐的)generation of children. One out of every three kids in America is now overweight. And I admire the First Lady's effort to end this within a generation. Safe Routes to School is a natural partner for Let's Move. For more than 10 years, Safe Routes to School has been making it easier for students to walk and bike from home to school. And ESS, where I walked today, is one of the earliest schools to participate.

    We know this program has been enormously effective because of the steady increase in the number of kids walking or biking to school. And as we made our way down the street this morning I was reminded yet again of this program's extraordinary work.

    Look, walking and biking to school is good for students' health. It's good for the environment. And it's good for the entire community's quality of life.

Everybody wins when kids take Safe Routes to School.

    You may need to give first aid. First aid is defined as the emergency care given to a sick or injured person. The goals of first aid are to prevent death and to prevent injuries from becoming worse.

    Each emergency condition is different. However, the following rules apply to any kind of emergency.

    Be aware of your limitations. Do not try to do more than you are able to. Nor should you do things if you are unfamiliar with them. Do what you can under the conditions at the time.

    Stay calm. Acting calmly will help the victim feel safe.

    Take a quick look to see if the victim is bleeding, and if there is a pulse.

    Keep the victim lying down and do not move him or her. You could make an injury worse if you move the victim.

    Take necessary emergency steps.

    Call for help or ask someone to make the EMS system (急救系统) start.

    Do not remove clothing unless you have to. If clothing must be removed, tear the clothes along the seams(线缝).

    Keep the victim warm. Cover the victim with a blanket. Coats and sweaters can be used if a blanket can not be found.

    Reassure (使…安心) the victim. Explain what is happening and that help has been called.

    Do not give the victim any food or fruits.

    Keep the bystanders (旁观者) away from the victim. Bystanders want to have a look, offer advice, and say something about the victim's condition. The victim may believe that the condition is worse than it really is.

    My first impression of Miss Vicki was a highly authoritative(权威的) person towering over me. She spoke in a loud voice and the earth shook whenever she marched. That was in the first year of high school. She was a knowledgeable literature teacher then. However, during my first year in school, she struck terror into my heart(使我胆战心惊). And everyone else's of course. Just the mention of her name made the most unruly classes silent.

    Nevertheless, the two years of junior high passed by rather quickly. Soon, I went to senior high class. I had worked hard and gotten the subject combination that I wished for. Together with a group of old friends, I soon settled down in class comfortably.

    To everyone's surprise, she was fortunate enough to be my teacher that year. I was shocked when I heard the news. This time round, however, I decided not to hide in terror whenever she was near. I decided to face the fact that we were going to meet each other for the next 365 days. Instead of trying too hard to lick her boots, I tried my best to my natural self in front of her.

    Still, I could not shake off the ice-cold impression that she put in my heart. True, her jokes sometimes sent me into fits of laughter, yet at other times these jokes simply fell flat the moment she told them. My lovely class, however, was already ready to laugh at the right time of her amusing stories. After all, we would not want to run the risk of provoking(激怒) her.

    Unluckily, life was not to remain boring. One day we received news that Miss Vicki was to leave Singapore for the Philippines where she would take part in a voluntary teaching program for the poor. We did not know what to say actually. All of us cried at the airport.

    People in developed countries are increasingly suffering from illnesses resulting from overeating. While starvation and hunger are still big problems in many poor countries in the world, more than 25 percent of the population in America and other western countries are obese. This doesn't just mean you are a little bit fat. It means you are more than 20 kilos overweight.

    Dr. John Colon from Ohio State University says the problem is only going to get worse.” As more women have gone out to work, you find that parents in general have less time to spend on preparing food. That's not just cooking, but also planning what to eat, doing the shopping and buying the fresh food. Families, therefore, increasingly rely on ready-made and frozen meals, which tends to be high in fat and contain a lot of additives(materials added to food to improve its taste) and sugar. The other thing is that parents seem to feel guilty about not spending so much time with their kids, so they tend to give more quickly to children's demands for things like sweets and chocolate.”

    Ben Brown. Who is a British Member of Parliament, blames the big food companies. He wants to ban any food advertising that is aimed at children. "The problem is that these companies spend millions of pounds selling food to children. It's all crisps (薯片) in the shape of dinosaurs and chocolate in the shape of Mickey Mouse. I meanwhat's going to be more fun to an sight-year-old —an ice cream with a free toy or an apple?"

    One food company thinks it has an answer to this: it has invented cheese-flavored cabbage and chocolate-flavored carrots. It developed the "Whacky Veg" with money donated by a cancer research charity, which found that a diet containing lots of fruit and vegetables helps reduce cancer. However, today's sweet-toothed kids need to be bribed(贿赂)into a healthy diet, and will only cat their greens if they taste different.

    Do you know that junk food isn't healthy? Of course you do! Do you eat it anyway? Of course you do! But a new study shows teaching adolescents about the ways food companies fool them into thinking junk food is cool can encourage kids to fight back—by eating healthier.

    The pull of junk food can be super-strong. It's designed to tasty; which makes eating well one of the great health challenges of our time. Everyone from doctors to the government has been trying to handle it. Yet we keep eating junk food.

    Professor Christopher Bryan says, "Food companies want you to want junk food." They spend millions of dollars coming up with new ways to^ promote junk food consumption. They hire scientists to make new junk food almost irresistible. They might do this, for example, by adding more sugar. Rats fed junk food for six weeks will even walk across a floor that gives them electric shocks just to get more of such food.

    Food ads often make unhealthy junk food seem healthy by featuring professional athletes, fit-looking pop stars and smiling, active teens. "We thought when the students learned this, it would matter to them," Bryan says. He worked with 8th graders at a Texas school. Half of them got a lesson Bryan created. It focused on the ways junk food is advertised, or marketed. A second group received lessons that focused on health. These lessons informed students junk food is had, and that foods like apples or carrots are a better choice. The students learned a bad diet can lead to major weight gain, and that being overweight puts people at risk for serious diseases. They also learned how eating well now can keep you healthy when you're older.

    After the lessons, the kids in both groups were asked how they felt about junk food. Most didn't have positive feelings about these unhealthy foods.
