The first ancient Olympic Games for which we still have written records were held in 776 BC. Coroebus won the only event at the Olympics. This made him the very first Olympic champion in history. Then they grew and continued to be played every four years. In 393 AD, the Roman emperor Theodosius Ⅰ, a Christian, announced to end the Games because of their pagan (异教的) influences.

    About 1,500 years later, a young Frenchman named Pierre de Coubertin began their revival (恢复). In 1892 Coubertin first brought forward his idea to revive the Olympic Games but failed.

    Two years later, Coubertin organized a meeting with 79 delegates (代表) who represented nine countries. At this meeting he got what he wanted. All the delegates at the conference voted for the Olympic Games. They also decided to have Coubertin set up an international committee to organize the Games. This committee became the International Olympic Committee (IOC) and Demetrious Vikelas from Greece was selected to be its first president. Athens was chosen for the revival of the Olympic Games and the planning was begun.

    The very first modern Olympic Games opened in the first week of April, 1896. Since the Greek government had been unable to afford a stadium, a rich Greek architect, Georgios Averoff, donated one million drachmas (over $100,000) to repair the Panathenaic Stadium, originally built in 330 BC.

    Since the Games were not well publicized internationally, contestants (选手) were not nationally chosen but rather came individually and at their own expense. Some contestants were tourists who happened to be in the area during the Games.

    Mark is always engaged in his work. But this time he felt that it was time for him to take part in his community, so he went to the neighborhood meeting after work. The area city council woman was leading a discussion about how the quality of life was on the decline. The neighborhood faced many problems. Mark looked at the charts taped to the walls. There were charts for parking problems, crime, and for problems in empty buildings. Mark read from the charts, “Police patrols cut back, illegal parking up 20%”. People were supposed to suggest solutions to the council woman. It was too much for Mark. “The problems are too big”, he thought. He turned to the man next to him and said, “I think this is a waste of my time. Nothing I can do would make a difference here.”

    As he neared the bus stop on his way home, Mark saw a woman carrying a grocery bag, and a baby. As Mark got closer, her other child, a little boy, suddenly ran into the street. The woman tried to reach for him, but as she moved, her bag shifted, and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. “You gotta stay with mom,” he said. Then he picked up the stray groceries while and the woman smiled in relief. “Thanks,” she said, “You've got great timing.” “Just being neighborly,” Mark said. As he rode home, he glanced at the walls of bus. On one of them was “Small acts of kindness add up.” Mark smiled and thought, “Maybe that's a good place to start.”

    Some materials are obtained from natural resources that are changed by chemical processes in a laboratory. The resulting artificial materials are synthetic, or human-made.

    Plastic is a synthetic substance, obtained from petroleum, a fossil fuel. The molecules（分子）in petroleum are split and then linked into chains. Plastic is an example of a polymer, a material made of repeating patterns of atoms linked together. Most polymers are synthetic. They are made by polymerization, the process of chemically linking many smaller molecules to form a larger molecule that has different physical features. Some polymers, such as proteins, occur naturally.

    Plastic is a key component of many products. When heated into an almost-liquid form, plastic can be made into fibers, sheets, or molds（模具）. It can be mixed with other elements to remain flexible, or it can harden into a solid. Plastic fibers can be made into clothing or carpeting. Sheets of plastic can be made into plates. Molded plastic can be sued for protective helmets or car bumpers.

    Most plastics can be reheated and remolded repeatedly. This feature makes plastic very easy to use. Polymers can be pulled into fine strings or molded into almost any kind of shape. For example, tubes of plastic can be shaped into bottles by different processes. One such process is extrusion blow-molding. Most plastics are also resistant to many chemicals that might harm other materials. This quality is the reason that so many cleaning liquids are packaged in plastic bottles.

    Plastics are good insulators that can stop electricity or heat to pass through. Look around your kitchen, and observe where plastics are used. Pot handles are sometimes made of plastic, as are cooking tools, toaster controls, and microwave cookware. Food-storage wraps and containers may be made of plastic. Take a walk outdoors, and note all the plastic items you see. Gardening tools, such as watering cans and sprayers, are often made of plastic. Swings and slides made of plastic do not become as hot as metal, so they are safer for play. Because plastics can be heated, remolded, and made into something else, they can be recycled and reused.

    As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input (输入) Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（笔画）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it."

    "I'm not in the mood to write when faced with a pen and paper."

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital, said, "Chinese characters enjoy both practical and aesthetic（审美的）value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

    It was December 25, 1914, only 5 months into World War I. German, British, and French soldiers, already sick and tired of the senseless killing, disobeyed their superiors and started socializing with "the enemy" along two-thirds of the Western Front.

    German troops held up Christmas trees with signs, "Merry Christmas". Thousands of troops ran across the battlefields covered with dead bodies. They sang Christmas songs, exchanged photographs of loved ones back home, shared food and even played football. Soldiers hugged men they had been trying to kill a few short hours before. They agreed to warn each other if their officers forced them to fire their weapons, and to aim high.

    Fear ran through the military leaders on both sides. They felt that their power was being challenged: soldiers declaring their brotherhood with each other and refusing to fight. Generals declared this unexpected peacemaking illegal and said that participating soldiers would face a military court. Those found guilty would be imprisoned or even shot. By March 1915 the socializing movement had been destroyed and the killing machine was back in full operation. Over the next three years more than fifteen million people died in the war.

    Not many people have heard the story of the Christmas Truce (休战). On Christmas Day, 1988, a local radio host in Boston played "Christmas in the Trenches", a song about the Christmas Truce several times and was stunned by his listeners' response. Thousands of people called in, praising the song, with many moved to tears by the amazing events it described.

    You can probably guess why the callers were in tears. The Christmas Truce story goes against most of what we have been taught about people. It lets us see the world as it can be and says, "This really happened once." It shows us the potential we have as humans contradicts all of those TV and newspaper stories that tell us how mean and heartless people are. It is like hearing that our deepest wishes really are true: the world really can be different.

Fans of art believe that its main purpose is to make us look at life from many different angles. When it comes to Cubism(立体主义), however, the artists of this era wanted us to look at life from every angle. 

The father of Cubism, Spanish artist Pablo Picasso, is among the art world's most famous names. Like many other great names before him, he felt restrained by the rules of his teachers and decided to do something: break them. 

Early in his painting career, Picasso realized something important about how people view and remember scenes of beauty. When we look at a subject, we don't just see it from one angle, as many paintings appear. Instead, we study the subject from a number of different angles, heights and viewpoints. This is the aim of Cubism: It portrays(描绘) subjects from a wide range of angles; it doesn't force us to see things as the artist viewed them at the time he or she painted them. To bring his visions to life, Picasso and other Cubists took the most basic components of a subject and rearranged them in a way which let us see it in full detail. 

"By breaking objects and figures down into distinct areas, Picasso aimed to show different viewpoints at the same time and within the same space," in the words of the Tate Institution. Or as Lithuanian—born Cubist Jacques Lipchitz once put it: "Cubism is like standing at a certain point on a mountain and looking around. If you go higher, things will look different; if you go lower, again they will look different."

Cubism stood out as it was an art movement which didn't just rely on the artist to share their vision by painting what they saw. As cubist paintings mainly show their subjects in a deconstructed form, this means that viewers must use their imaginations to find the missing pieces for themselves. As Guardian art critic Johnathan Jones noted, this is part of the beauty of enjoying Picasso's works. "If you can relax your gaze(凝视)enough and just enjoy the painting long enough, something really amazing happens. Your mind produces a solid feeling of the things Picasso was looking at. the world is revealed in its majesty(壮观)," he wrote.
