Glacier Bay is one of the most famous parks in America, located in the state of Alaska. This park in the southeastern part of the state covers more than 1 million hectares of Alaskan wilderness. It includes mountains, glaciers (冰川), bays, and even rainforests. Glacier Bay supports hundreds of kinds of animals, including many species of birds, fish, bears, whales and sea lions.

    As its name suggests, much of Glacier Bay National Park is covered by glaciers. A glacier is a large area of ice that moves slowly down a slope (斜坡) or valley, or over a wide area of land. Glaciers cover more than 5,000 square kilometers of the park.

    Glacial ice has shaped the land over the last seven million years. The glaciers found in the park today are what remains from an ice advance known as the Little Ice Age. That period began about 4,000 years ago.

    During the Little Ice Age, the cold weather caused the ice to grow and advance. That situation continued until about 1,700s, when the climate began to warm. The higher temperatures caused the ice to start melting. That melting led the huge glacier to separate into more than 1,000 different glaciers.

    The extremely tall and jagged (参差不齐的) mountains seen in Glacier Bay National Park were formed by the ice advancing and then melting over time. The melting of the ice also created water that filled in and created the many fjords (峡湾) within the park. Fjords are narrow parts of the ocean that sit between cliffs or mountains.

    The huge amount of water from the melted ice killed off many kinds of plants. Vegetation returned to the area over the next 200 years. The regrowth in plants also brought back many animals to the land. This return of life to Glacier Bay is why it is sometimes called “a land reborn” by people.

    Can you imagine four hours of your day getting to and from work? For the last eight years, Jo Meade rode her bike each Sunday on a 16-mile round trip to her job washing dishes. It took more than an hour each way. Other days of the week she would spend two hours on three buses from her apartment to get to the other work, for a four-hour round trip.

    That was the “before” part of her life. The “after” part of her life was started by the community Police Officer Trevor Arnold, who delivered a used car to her with the help of a car dealer and other donors.

    Arnold, who spotted Meade, red and sweaty, riding her bike in the worst heat this summer, decided he would het her a car. He intended to quietly buy her a used car out of his own pocket so he turned to his friend Kody Slaght, a car salesman to ask about a car priced $1,000. That wasn't enough for a reliable ride, Slaght said, but the dealership said they would find a good car for her at a good price. Soon others were donating. Slaght and Arnold wouldn't say how much the car cost, but the value is about $4,000.

    Arnold said he was motivated by Meade's work ethic（职业道德）to help. “I see a lot of hardworking people nut that's when they are at work. Can you imagine spending four hours of your day getting to and from work?” he said.

    Meade's boss said she was awesome and really reliable when she worked and she got along with others. “She's willing to rise the three buses to get in here on her day off if we need her too.”

    Meade said she was planning to buy a car, “but I haven't been able to afford it,” she said. “Trevor, he is a very good guy. I did not expect this.”

    Forests are always losers at the Olympics, and that's unlikely to change anytime soon.

    For the winter games in PyeongChang, South Korea, virgin forest was destroyed on Mount Gariwang to accommodate ski runs. For the 2022 Winter Olympics in Beijing, a ski run is set to wipe out part of the Songshan National Nature Reserve. And let's not forget the 240 acres of Atlantic Forest that were leveled for the 2016 games in Rio de Janeiro to make way for a golf course.

    For the upcoming Tokyo games, environmental and human rights advocates have been raising alarms about the use of tropical (热带的) wood to build the New National stadium. Activists have fought against such environmental destruction. The damage is often permanent, threatens endangered plants and animals and in some cases, causes conflicts with native people. But frequently the country's organizing committee, and the International Olympic Committee (IOC) have found ways to make it reasonable — despite a paragraph in the Olympic Charter (宪章) that states that the IOC's role is to "encourage and support a responsible concern for environmental issues".

    "As it stands now, the IOC has little authority over a city's local organizing committee, which finally plans the event, " Chappelet, professor of public management at the University of Lausanne, told Earther. "Even if the IOC is dissatisfied with the way host cities have prepared for the games, they have no built-in systems to watch them so that they strictly follow the Olympic Charter." The only thing they can do if they're not happy is to withdraw (= take back) the right to organize the game. "But the IOC could include more enforcement (执行) systems into the contract they make with the host city," he added. That contract must be signed and obeyed by everyone and those who break it must be fined.

    Boykoff, the author of several books on the Olympics, suggested a similar solution. "The IOC could insist that host cities take their ecological (生态的) promises into account first, but instead they look the other way, time and time again," he said.

    Tonya, Elsa and Mark are students at LaGuardia High School in New York City. It's a school with regular academic (学术的) classes, but it also gives special attention to the performing arts. Tonya likes dancing, Elsa wants to be an artist and Mark is a singer.

    The students are all 15, and they're in 10th grade. They study subjects like English, math, social studies, science and PE. They also choose a foreign language: French, Italian, Spanish or Japanese. Students have many academic classes, but during the school day they also take classes in the arts, like theater, art, dance and music. Mark says, “I get the basic classes, but I also take a voice class and a music history class.”

    There is even more for LaGuardia students after school. There are more than 40 clubs for students. For example, there's a movie club, a music club and an environment club. “We have so many choices here,” says Tonya. “My favorite club is the camera club. I like taking photos. It's also a great way to meet people with common interests.”

    Students at LaGuardia can also do many sports. For example, they can play basketball, tennis, volleyball and soccer. Elsa is on the gymnastics team. She says, “I like being on a team. It makes me work hard and do my best.” Students practice after school. They compete against other high schools. Mark says, “At school, I study by myself. I'm a singer, and I do that alone, too. That's why I like playing on the basketball team. We work together and compete against other teams.”

    LaGuardia offers many great classes, clubs and sports for students. Students at LaGuardia get a good education and they also develop their own interests. Many LaGuardia students become dancers, singers and actors!

    Is smile just a facial expression? Of course not! It is not only used to express pleasure, affection, and friendliness, but also the commonest way to show our good will perfectly without saying anything. A Chinese saying runs： “Never hit a person who is smiling at you.” It is a time-proven fact that smile is a language all its own—a universal language—understood by the people of every nation in the world. We may not speak the same tongue as our foreign neighbors, but we smile in the same tongue. We need no interpreter for thus expressing love, happiness, or good will.

    One day while shopping in a small town in southern California, it was my misfortune to be approached by a clerk whose personality conflicted with mine. He seemed quite unfriendly and not at all concerned about my intended purchase. I bought nothing, and marched angrily out of the store. On the outside stood a young man in his early twenties. His expressive brown eyes met and held mine, and in the next instant a beautiful, brilliant smile covered his face. The magic power of that smile made all bitterness within me melt, and I found the muscles in my own face happily responding. “Beautiful day, isn't it?” I remarked, in passing. Then, obeying an impulse(冲动), I turned back. “I really owe you a debt of gratitude,” I said softly. His smile deepened, but he made no attempt to answer. A Mexican woman and two men were standing nearby. The woman stepped forward and eyed me inquiringly. “Carlos, he no speak English,” she volunteered. “You want I should tell him something?” At that moment I felt changed. Carlos' smile had made a big person of me. My friendliness and good will toward all mankind stood ten feet tall. “Yes,” my reply was enthusiastic and sincere, “tell him I said, 'Thank you!' “Thank you?” The woman seemed slightly confused.

    I gave her arm a friendly pat as I turned to leave. “Just tell him that.” I insisted. “He'll understand, I am sure!”

    Oh, what a smile can do! Although I have never seen that young man again, I shall never forget the lesson he taught me that morning. From that day on, I became smile-conscious, and I practice the art diligently, anywhere and everywhere, with everybody.

    As a young boy, I knew what people said was not always what they meant or were feeling. And I knew it was possible to get others to do what I wanted if I read their real feelings and responded(回应) suitably to their needs. At the age of eleven, I sold sponge rubber(泡沫橡胶) door-to-door after school and quickly worked out how to tell if someone was likely to buy from me. When I knocked on a door, if someone told me to go away but their hands were open and they showed their palms (the inside surfaces of their hands), I knew it was safe to continue with my presentation(展示) because they weren't angry or threatening although they may have a dismissive(不屑 ) attitude. If someone told me to go away in a soft voice but used a pointed finger or closed hand, I knew it was time to leave.

    As a teenager, I became a pots and pans(炊具)salesperson, and my ability to read people earned me enough money to buy my first house. Selling gave me the chance to meet people and study them close and to know whether they would buy or not, simply by watching their body language.

    I joined the life insurance business at the age of twenty. And I went on to break several sales records for my company, becoming the youngest person to sell over a million dollars' worth of business in my first year. This achievement allowed me to become a member of the well-known Million Dollar Round Table (MDRT, which recognizes the world's top achievers in life insurance). I was lucky that the skills I'd learned as a boy in watching body language while selling pots and pans could be used in this new area, and were directly related to the success I could have in any business closely connected with people.
