When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie,“ Homeless to Harvard: The Liz Murray Story”, shown in late April.

    Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

    Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “What drove me to live on had something to do with understanding, by understanding that there was a whole other way o f being. I had only experienced a small part of the society,” she wrote in her book Breaking Night.

    She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”. She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS.“I love my parents so much. They are drug addicts. But I never forget that they love me all the time.”

    Liz wants moviegoers (who often see films) to come away with the idea that changing your life is “as simple as making a decision”.

    The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru's heartbreaking story could have one good consequence — other countries might learn from its mistakes.

    For thousands of years, Polynesian people lived the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.

    However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.

    Nauru's real troubles began in 1899 when a British mining company discovered phosphate (磷酸盐)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which a very important fertilizer for farming. The company began mining the phosphate.

    A phosphate mine is not a hole in the ground; it is a strip mine. When a company strip-mines, it removes the top layer of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.

    In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.

    Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.

    With the start of the new term, the students around the country exchange their fun and fashionable clothes for boring school uniforms. But not all schools are fashion deserts. Colorful sports shoes, school bags, T-shirts and even drink containers are breathing life into campuses.

    "The uniform makes us look like a bunch of clones, especially when we are doing morning exercises on the playground," said Qing Pei, a Senior 2 from Shanghai Qibao High School. "But the boys wear different sports shoes and girls have different decorations in their hair. These are the areas where you can express yourself," said Qing.

    Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.

    "Nike and Adidas basketball shoes, although they are still the must-have items for many of my friends, are becoming out-of-date," Qing added. He explained that "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn."

    "Still in fashion are the various baseball caps and American-style T-shirts with random (随意的) English words printed on them," said Qing. "The accuracy of the written message is not important. Often, the words are misspelt. Sometimes they do not even make sense, "Qing said with a smile.

    Besides sports shoes and T-shirts, styles and colors of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls.

    Other fashionable items are the colorful drink containers which are now popular among girls this term.

    "Some teachers are surprised to see a teenager sucking a bottle like this at school and criticize it as a childish regression (退化). But some girls just love it," said Yang Rui, a Senior 3. from High School attached to Xi'an Jiaotong University.

    China is known for its long history, rich culture, and cute pandas. It's also known for some of the worst air quality in the world. But the Asian country is now using a natural weapon against air pollution – trees.

    In February, China's government announced plans to cover at least 32,400 square miles with forest. That is about the size of Ireland. Some 60,000 soldiers will take charge of the tree-planting program. Most of the trees will be planted in Hebei Province. That is an area surrounding China's capital, Beijing.

    Huang Wei is an environmentalist who works for Greenpeace East Asia. She is optimistic about the plan. “Trees act as a sink to absorb carbon dioxide and other pollutants,” she said. Carbon dioxide is a gas that traps the Earth's heat. It contributes to global warming.

    Why is China's air filled with harmful chemicals? It's because the country relies on coal-fired power plants. When coal is burned, PM2.5 is produced, PM2.5 is a pollutant. It can cause shortness of breath, heart attacks, and even death.

    Just two years ago, pollution levels were so high in Beijing that schools and factories had to close. Huang hopes China's tree-planting plan will reduce the nation's suffering from air pollution.

    The Chinese government is getting help from others in its drive to make the nation greener. Stefano Boeri is an Italian architect and urban planner. He is leading an effort to plant vertical（垂直的）forests in China.

    Boeri's designs have already taken root in the city of Nanjing, China. That's where the Nanjing Green Towers are under construction. The building has two towers. Thousands of trees and hanging plants will grow on the balconies and rooftops.

    Boeri says his goal is to design buildings that help the environment and improve air quality. He also hopes to encourage a new generation of green architects.

    About one in ten video game players shows signs of addictive behavior that could have negative effects on their family, friends and school work, according to a new study conducted in New York.

    Researchers at Iowa State University(ISU) and the National Institute on Media and the Family found that some gamers show at least six symptoms of gambling addiction such as lying to family and friends about how much they play games, using the games to escape their problems and becoming restless when they stop playing.

    They may also skip homework to play video games or spend too much time playing games and do poorly in school. "While the medical community currently does not recognize video game addiction as mental disorder, hopefully this study will be one of many that allow us to have an educated conversation on the positive and negative effects of video games," said Dr. Douglas Gentile, an assistant professor of psychology at ISU.

    Dr. David Walsh, the president of the National Institute on Media and the Family which tries to reduce the harm of media on the health and development of children and families, said the findings are a wake-up call." This study gives everyone a better idea of the problem," he explained.

    The researchers, who studied 1,178 American children and teenagers, aged 8 to 18, found some displayed at least 6 of 11 symptoms of pathological (病态的) gambling as stated by the American Psychiatric Association. Addicted gamers played video games 24 hours a week, twice as much as casual gamers. Some addicted gamers even steal to support their habit, according to the findings that will be published in the journal Psychological Science.

    While video games can be fun and entertaining, some kids are getting trouble. "I continue to hear from families who are concerned about their kids' gaming habits. Not only do we need to focus on identifying the problem, but we need to find ways to help families prevent and treat gaming addiction.

    It is reported that a record-breaking high-speed rail will connect Inner Mongolia in the north to Hainan in the south. According to the Shaanxi Development and Reform Commission, the proposed line will operate at a speed of 350 kilometers per hour(217 mph).

    Beginning in Inner Mongolia's Baotou city and running through southern Shaanxi, Hubei, Hunan, Guangxi and Guangdong, its final stop would be in Haikou city on Hainan Island, China's southernmost province.

    Though the exact length of the proposed route has not been released, it will likely become the world's longest high-speed rail line as the journey by road between Baotou and Haikou is approximately 3, 000 kilometers(1, 864 miles) long. Currently, the world's longest high-speed rail line is almost 2, 300 kilometers long (1, 429 miles), running from Beijing to Guangzhou.

    The proposed rail is part of China's aim to create another "Silk Road of the 21st Century" and improve the country's transportation network while driving land development and urbanization(城市化) in some provincial areas.

    Many of the provinces through which the high-speed trains will travel are near major bodies of water, such as the Yellow River in Inner Mongolia and Shaanxi province, the Yangtzi River in Hubei and the South China Sea, where the line would end. It will also take passengers to popular tourist attractions including Zhangjiajie, Xi'an, Guilin and minority areas in western Hunan and Hubei.

    "The country is now shifting its focus and investing in the western regions and economically underdeveloped areas, making up for China's long debt to these areas, " Tan yuzhi, professor of the School of Economics and Management at Hubei University for Nationalities, told local media. " The project will significantly narrow regional disparities(差异) and solve minority issues."

    However, Deng Hongbing, director of China University of Geosciences' Center for Regional Economic and Investment Center, said that if the north-to-south railway is to go ahead, there needs to be a sound ecological program in place to ensure the protection of these underdeveloped and ecologically sensitive areas.
