Here are four pieces of news from China Daily:

    SHANGHAI—The Huachen Group, which has put 83 million yuan in the development of the commerce market since its official registration late last year, recently held a meeting in Shanghai to show the use of its newly opened tourism business payment network. The network aims to serve tourists from all over the world, but especially from Europe and the United States where credit cards are popularly used. After opening the www.ehinaeonet.com website, netizens can get information about hotels and tourism services on tourism page. Hotels and services can be reserved and payment made through credit cards. The network opened in February in Beijing.

        SYDNEY—The Sydney Olympic flame will travel underwater on Australia's Great Barrier Reef during the torch relay following a successful test.

        Scuba diver Wendy Craig, a marine biologist, will carry the torch on three-to-four-minute underwater journey at Agincourt Reef on June 27, creating Olympic history, organizers said yesterday.

        Burning at 2,000 degrees, the torch is expected to remain alight three meters underwater because of a special kind of technology which creates a “fierce flame”— too powerful to be drowned out by water. Charles Tegner, managing director of torch creator, said the flame would burn like a flame from oxygen-producing chemicals.

        BEIJING—The election of a new leader in Taiwan cannot change the fact that Taiwan is part of China. “Taiwan Independence” in whatever form will never be allowed, according to a statesman of China's central government.

        “We should listen to what the new leader in Taiwan says and watch what he does. We will observe where he will lead Cross-Straits relations. We are willing to exchange views on Cross-Straits relations and peaceful reunification(统一) with all parties, organizations and people in Taiwan who favor the one-China principle,” says the statesman, from Taiwan Affairs Office of the CPC Central Committee.

        HAIKOU—Customs officers in Haikou, capital of South China's Hainan Province, recently stopped a boat loaded with 781 cases of foreign-brand cigarettes being smuggling into China. The cigarettes are estimated to be worth more than 1.8 million yuan, said a customs officer. They discovered the smuggling boat as they were going around the northern sea area of Yangpu Port.

        The smuggled cigarettes cases, packed into two containers, were disguised to avoid being examined. The boat was registered in the coastal city Xiamen in East China's Fujian Province. All eight suspects aboard the boat were kept by the police in Haikou.

    When Russell Lyons volunteered for the first time, he read “Goodnight Moon” to a class of San Diego preschoolers. And it wasn't reading — he'd memorized the book and was reciting it out loud. He was 4. Still, he said it felt good there, in front of the other kids, lending a hand. He wanted more of that feeling.

    Thirteen years later, he's getting a lot of it. He's on a five-month road trip across America — not sightseeing, but volunteering.

    The University City resident has spent time at an animal reserve in Utah, a women's shelter in St. Louis, a soup kitchen in New York, a retirement home in Tucson. This week he's in Los Angeles, at a program that supports disabled youth.

    “I just like helping people and feeling that something I do is making a difference,” he said. He resists the idea that his “Do Good Adventure” is all that unusual. It bothers him that the media often describe young people as lazy, self-centered. So he sees his trip as a chance to make a statement, too. “About 55 percent of teens do volunteer work, higher than the rate for adults” he said, according to a 2002 study. “Not everybody knows that. ”

    Of course, some teens do volunteer work because it looks impressive on their college applications. Lyons said he mentioned his trip on his applications. But charity work is a habit with him. Even before the cross country trip, he was volunteering about 200 hours a year at various places. He's made sandwiches for homeless families in Washington D.C. He's taught math to fifth-graders in Cuernavaca, Mexico.

    He gets some of that drive from his mother, Lesley Lyons, who has been involved in nonprofits for much of her life. She was there when her son “read” to the preschoolers — a memory of hers “that will never go away.”

    In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies,“No, thanks. I've got a good horse under me.”

    The city planners decided to build an underground drainage(排水) system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.

    An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.

    This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire bulidings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like the Tremont Hotel, which was a six-story brick building?

    That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like Tremont Hotel, Pullman would place thousands of jackscrews(螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10 jackscrews. At Pullman's signal each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stayed open during the entire operation, and many of its guests didn't even notice anything was happening.

    Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.

    Since so much written language we see today comes from a glowing screen, language has begun to change through our interaction with technology. Social media and the Internet have had a rapid and great effect on the English language, and not necessarily for the better. More and more people have found themselves writing in pieces of words and using unclear acronyms(单词首字母) both in written and spoken language.

    How many times have you typed "LOL" in response to a humorous message? Referred to someone as your "BFF"? Exclaimed, "OMG!" during a particularly shocking event? Social media has affected the words we use in our everyday life. Abbreviations and acronyms commonly known as "text talk" have made their way into both spoken and written language. These are becoming increasingly popular as people struggle for brief expressions to meet word limits on social media like Weibo and Twitter. In addition, the speed of the Internet means language is changing faster than ever. You no longer have to be published through physical and traditional means to bring word trends to public attention.

    Many people believe the overuse of these new terms is a passing trend, and nobody will be using them in just a couple of decades. With the change of language, older terms will surely disappear and fall out of style, and newer and more Internet language will take their place.

    But the Oxford English Dictionary thinks the contrary. In 2011, a lot of Internet terms including, "LOL," "BPB," "OMD," and "BFF" were added to the dictionary, making these acronyms official parts of the English language. According to the dictionary writers, these terms aren't going anywhere anytime soon.

    The words you use in everyday life are a reflection of yourself; this is especially true on the Internet with the lack of interaction in real life. With the Internet and social media rapidly getting popular, soon your words may be all you have left. Make them good ones.

    Devon Gallagher, a college graduate from Philadelphia, wants the world to know exactly where she's been while she's on her worldwide vacation in a special way. The traveler, who was born with a bone disease, had her right leg amputated (截肢) at the age of four. Although the amputation caused inconvenience for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.

    To spread that message. Gallagher has gone to social media, where she shares photos of her travels across the world, but instead of simply using a geo-tag (地理位置标签), she writes her location on her artificial leg before taking a picture.

    Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking in the beautiful Parthenon temple in Athens and enjoying a river ride in Budapest, all with the well-known locations written on her artificial leg.

    "I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalk-board," Gallagher said. "My mum and grandmother didn't like the idea, but my friends thought it was great and told me to go for it, so I did."

    Gallagher said people often stare when she's writing on her leg, but once she shares the photos, she receives only positive feedback (反馈), "My leg hasn't stopped me from doing anything I've wanted to do," she said. "I don't know if it's my determination to prove to myself that I can do it, anyway, I've been able to keep up with people at my age and lead a pretty great life."

    Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art.
