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 who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that loss 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 of 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 loved me all the time.”

    Liz wants moviegoers to come away with the idea that changing your life is “as simple as making a decision”.

Hobbies Help Cure Addiction to the Internet

    While some parents have expressed concerns about the amount of time their children spent surfing the Internet during the summer break from school, it wasn't a problem for Yin Qiming.

    Instead, the 37-year-old Shanghai resident and his daughter divided their vacation between cyberspace and the 8-year-old's other interests.

    “My daughter has many hobbies and I and her mother respect her choices, so we accompany her to classes she enjoys, such as learning to play the drums and drawing,” he said.

    “She loves to play outside with her friends, so she doesn't think the Internet is a must-have thing in her life.”

    Yin added that he rarely imposes a time limit on his daughter's online activity.

    “She sometimes uses WeChat (a popular instant-messaging tool) on my mobile phone, but only to contact her mother,” he said. “Once she has her own plans every day and realizes that the internet is just a part of life, she won't become addicted to it.”

    Li Lin, a primary school teacher from Liaoning province, expressed a similar opinion.

    “We do some homework online, including reciting stories, and the children use the Internet frequently every day of their lives,” she said, noting that the children's online activity is limited to 30 minutes a day at school.

    “We should make better use of the Internet to provide children with more knowledge and help them to grow up,” said Li, who has a 10-year-old son.

    The key to preventing children, especially those at primary and middle schools, from becoming addicted to the Internet is to limit the time they spend online and to ensure that they know cyberspace cannot replace traditional forms of communication, she said.

    Mao Feizhu, a psychologist from Fujian province in southeast China, said people overestimate the influence of the internet.

    “Many people, even some parents, believe the Internet plays a big role in our daily lives, and many things can be completed online, but that's not completely right,” she said.

    “We can use social applications to talk or play basketball games, and even share what we are thinking about, but sometimes it's impossible for our emotions to be accurately reflected in this way. What children need is emotional communication and real physical exercise. After all, love cannot be bought on the net,” she said.

    Perhaps, the best way to stop young netizens spending too much time online is to encourage their other interests but also accompany them when they go online: “We should use the Internet, not become its slaves.

    Author Avi, winner of a Newbery Award, a Scott O'Dell Historical Fiction Award, and several Boston Globe-Horn Book Awards, may have seen his first children's book published in 1970, but that doesn't mean he's lost his talent for connecting with young fans.

    The American writer, born in 1937, agrees that getting involved with his readers is one of the key reasons he keeps writing, and that he's been fortunate enough to hear directly from readers about the impact (影响) his books have had. “I have been touched many times by readers who find some special connection between their lives and something I have written: the Danish girl who read something of mine in Danish, and struggled to communicate that in her poor English; the autistic (自闭症的) boy who somehow found something meaningful about my books that reached his own inner life; the women who have told me how important The True Confessions of Charlotte Doyle was to them when growing up."

    Beyond his fans' questions about the characters he's created, the writer's most commonly heard question may be about his own use of the single name “Avi." “As a young adult, I was a reader of French literature, which has that one name tradition: Moliere, Racine, Anouilh, Gide, and so on," he explains. “Avi was given to me by my twin sister when we were very young children, and it stuck. Then my family discouraged me from taking up writing as a career because they considered my writing poor. By using Avi, I was showing my determination to them."

    Although he believes－and has the awards to show－that his writing skills have improved, writing still doesn't come easily to him, despite having over sixty books to his credit. “I never studied writing in any formal sense. I taught myself to write by reading, and by imitating what I was reading," he says.

    The writing task may be tough, but the payoff is big. “To create, share, and support the gift of reading and literature, is to give young people the gift of many worlds, within and without," Avi states.

    News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world's first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.

    Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That's why many news anchors were worried: Will AI replace us in the near future?

    To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.

    Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person's voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs

    Both the technologies used to make Xin's performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don't always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.

    Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. "What could be causing everyone to act this way?"

    Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice: flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.

    Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, "My report is on George Washington, the man who started the American Revolution." The whole world became quiet! How could I know that she meant that George Washington?

    Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster's office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet!

Bradley McConachie, a 33-year-old Australian is actually a student in international relations completing his PhD through Griffith University. He came to Beijing for a cooperative research at Beijing University two years ago. Such an academic life was colorful with a chance offered by the cultural exchanges project, "I'm in China".

Bradley was lucky to win the most "likes" for his photo story about his life in China and became one of 20 winners to visit locations by the project this summer. All the winners' experiences were filmed to produce a reality show, My Chinese Working Day, which will be broadcast by mid-September.

Bradley was chosen to work as a recreational manager for a Chinese wedding. The film crew took them to many "amazing sites" and the staff at the resort taught them a lot about how to incorporate modern Chinese features while still keeping traditional customs.

"I would have to say two things stick out as the most memorable: the helicopter ride and talking with the staff at the hotel about how they organize weddings here in China," he said. That was Bradley's first time to be in a helicopter, and he was too absorbed with the "stunning" view of the coastline.

"I think it is so important to show other Australians the different landscapes China has to offer. I think so many Australians, when they think about China, imagine the historical sites of Beijing and the exciting things to see in Shanghai but have no idea about other beautiful places, like Sanya or the many other places people have been taken to in this TV series. It was nice to experience these little touches. I was happy to be a part of that experience!" Bradley said.
