Article: He is not just a classical music superstar. He is a global superstar. Only 27 years old, the Chinese pianist Lang Lang has become an inspiration to tens of millions around the world. Among his dazzling long list of titles, Lang considered UNICEF goodwill ambassador the most special one. "Being a UNICEF goodwill ambassador is the best decision I have made and will definitely be the best experience in my life," Lang said in a recent interview with Xinhua at the UN headquarters in New York. "I love children very much, and playing piano for them is my favorite," Lang said, beaming with delight. Named this year by Time magazine as one of the 100 World's Most Influential People, the pianist said he hoped music could "bring children happiness and enlighten their life." Three months after his nomination , Lang went to Tanzania with the UNICEF team to visit children threatened by malaria and AIDS. Although the southeastern African country's underdevelopment and harsh living conditions surprised Lang who landed the continent for the first time, he was touched by local children's passion for music. "Most of the kids had never seen a piano before," Lang said. "When I played Chopin's nocturne or waltz to them, those who were too shy to talk to me suddenly became active and began to share with me about their dreams. How amazing it is!" "Music can bring hopes to the kids and open their mind," he said. Following his visit to Africa, Lang began to organize fundraising concerts for children. Now it has become his routine to do 15 to 20 fundraising concerts every year. Except for his efforts on fundraising, Lang also established his own international music foundation last year to assist young talents to play piano. So far Lang has chosen five children from the United States and Germany, providing them with scholarships and opportunities to perform at world-class music halls, he said. In December, he will start the selection in China where he would like to "focus more on physically challenged kids, like blind kids." Question: As a UNICEF goodwill ambassador, Lang Lang's work is mainly to _ . Yes or no, is the answer "help children who are in great need"?

Article: As you move around your home, take a good look at the things you have. It is likely that your living room will have a television set and a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week. Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the long-hours work culture to make more money to buy more things is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of living and _ is one of them. Six percent of workers in Britain took the decision to downshift last year. One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs , leaving their two children with a nanny . Most evenings Daniel wouldn't get home until eight or nine o'clock, and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by. Nowadays, they run a farm in the mountains of Wales, "I always wanted to have a farm here," says Daniel, "and we took almost a year to make the decision to downshift. It's taken some getting used to , but it's been worth it . We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it's made us stronger as a family, and the children are a lot happier." Liz, however, is not quite sure. "I used to enjoy my job, even though it was hard work and long hours. I'm not really a country girl, but I suppose I'm gradually getting used to looking... Question: When Daniel was a reporter, he _ . Yes or no, is the answer "was well paid"?

Article: Backpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don't mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home. Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia2 and the Marine Biological Laboratory in Woods Hole3, Mass. 4, have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and- rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS)5 receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack's electricity-generating feature could dramatically reduce the amount of a wearer's load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9 Science6. The backpack's electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer's back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7.4 watts. Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack's oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack. The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power- generating backpacks could make it possible to walk, play video games, watch TV,and listen to music, all at the same time. Electricity-generating packs aren't on the market yet, but if you do get one eventually,... Question: Backpacks are convenient because Yes or no, is the answer "your hands are freed to do other things."?
