Can you remember the first time you learned to ride a bike or drive a car? Learning these skills changed your life forever and opened up new horizons. Learning about computers can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills , you will never go back to the old days. The new technology is simply too convenient and too powerful.

    Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities. Today we see one of the most dramatic technologies ever developed—the computer. It extends the capabilities of our minds.

    Computers have saved organizations millions of dollars. Furthermore, these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer may multiply what we can do, and the return on investment is high. The growth of computer usage is surprising. On the other hand, the computer can do serious damage. Invasion of privacy(侵犯隐私), fraud(欺诈), and computer-related mistakes are just a few shocking examples.

    The computer is like a double-edged sword. It has the ability to cut us free from some activities, but it can also cut deep into profits, personal privacy, and our society in general. How it is used is not a function of technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours, and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many, many benefits of the computer age.

    Flying for a long time, you finally arrive at the place where you can relax—your hotel room. Now you throwyour bag on the bed, turn on the TV and watch an international news programme on a satellite channel probably from UK or the USA.

    The main international broadcasters are BBC World and CNN. With an audience of over 1.5 billion people, these are popular channels that offer good-quality news programmes. In both companies, the journalists are experienced writers that produce journalism of a high standard.

    However, there are alternative news channels which people watch because they want a less traditional or non-Western view on world events. Russia Today and Al Jazeera International, an Arabic company, are international channels that broadcast in English. Both companies say they give a fresh view on big stories, and their experienced journalists often report from places where Western journalists do not work, and so they give us stories that we don't normally see.

    The Internet offers more variety. OneWorldTV is an Internet site where you can find stories about the developing world and human rights, rather than the usual stories about US politics and business. The writers for this company are often local people who write the stories for free. This non-professional journalism is increasing, and it certainly offers more choices.

    This increase in citizen journalism means that you can write the news, too. Main news broadcasters often use photographs and stories that members of the general public send to them, especially when there is a dramatic breaking news story. Besides this, some blogs are popular sources of news, and the website NowPublic lets you write stories using information you can get from anywhere, including sites like Youtube, Flickr and Twitter.

    Hundreds of children are being treated for sleep problems in Wales every year. In some cases, babies, infants and teenagers have been admitted to hospital while in north Wales alone.

    The Children's Sleep Charity said many children were suffering from lack of sleep mainly because of technology use. Public Health Wales said sleep was as important to a child's health as healthy eating and exercise, and children with poor sleep patterns were more likely to be fat.

    Statistics obtained under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013.

    Children aged between 0 and4 made up the highest number of inpatients (住院病人), with some newborns being treated for sleep-related problems from the day of birth.

    Vicki Dawson, who set up the Children's Sleep Charity (CSC), said sleepless nights were putting both children and parents in anxiety. "Their weight and growth may also be affected as well as their mental health," she said.

    Teachers said children showing signs of sleep shortage and tiredness in class were a concern as they couldn't concentrate for long periods.

    Psychologist Amy McClelland, of Sleep Wales, said a common problem was children being "over excited" and "not having the chance to relax property" before bed and families should get back to basics. "Think 1950s family home. Dinner as a family, read, chat, a film maybe, lights off and then bed." She added.

    Shan Tianfang, died at 83 on Sept. 11, 2018 in Beijing because of multiple organ failure. His energetic oral interpretations of classical Chinese novels and historical events pushed the ancient pingshu tradition forward into the modern age for generations of Chinese.

    Mr. Shan tried for many years to avoid becoming a performer of pingshu, the Song dynasty-era storytelling tradition. Growing up in the1950s in a family of folk art performers, he had seen struggle firsthand. It was a life of constant financial troubles and low social status. So it was with great unwillingness when, out of financial necessity, he became an apprentice(徒弟) to a family friend who was a master of pingshu. He made his first public appearance in 1956.

    In the pingshu tradition, the performer wears a traditional gown and sits behind a desk equipped with a folding fan and a wooden block. The storyteller tells a legend — typically a classical Chinese epic — from memory, using different voices and exaggerated gestures as well as adding occasional background detail and commentary.

    Mr. Shan grew to love the storytelling form, which is popular across northern China. It is a demanding profession that combines acting, oration, writing, historical research and literary criticism and requires countless hours of memorization. In teahouses around the northeastern region, he became famous for his fresh takes on the classics.

    In 1976, many Chinese were hungry for some new forms of entertainment, and it was against this background that he grasped the opportunity to record a pingshu radio broadcast. He soon discovered that performing on radio was vastly different from doing so in teahouses. There were no props(道具), no reactions from the audience to guide him — just Mr. Shan and the microphone in a recording studio. So for his first radio performance, a shortened version of the historical novel. The Romance of Sui and Tang Dynasties, Mr. Shan used the studio's three recording technicians as his audience and adjusted his performance based on their reactions.

    The performance had its first appearance in 1980 on Chinese New Year, and more than 100 million Chinese were estimated to have tuned in during the 56 hours over which it was broadcast. It was the beginning of a dramatic second act both for Mr. Shan and for pingshu in the People's Republic of China. He was soon a household name across the country.

    Over six decades, Mr. Shan recorded more than 110 stories for radio and television totaling about 12,000 episodes and lasting 6,000 hours. His best-known works include his interpretations of Chinese classics like 'White-Eyebrow Hero' and 'Sanxia Wuyi' and his dramatizations of historical figures like Zhuge Liang and Lin Zexu.

    Even today, hop into a Beijing taxi and the driver may be listening to one of Mr. Shan's recordings. "For my generation, Shan Tianfang was a master," said Zhao Fuwei, 48, a Beijing taxi driver. If back then there was such thing as a viral star, then Shan Tianfang was definitely the hottest viral star.

    "Listening to his stories has made it easier to kill time in bad traffic," Mr. Zhao added. "He was so good at making complicated historical stories simple and interesting". You feel like you could empathize with the characters in his stories, even though they lived a long time ago.

    But in recent years many of the great pingshu performers have died, and the tradition is fading. By the time Mr. Shan retired in 2007, interest in pingshu among Chinese had all but been replaced by mobile phones and gaming. Nevertheless, even after retiring, Mr. Shan worked tirelessly to promote pingshu among young Chinese, instructing apprentices and starting a school dedicated to the folk arts.

    Ever willing to adapt to new technologies, he posted a message to his Sina Weibo microblog account on Sept. 6, five days before his death. It was an announcement about a new live-streamed(直播) lecture series about pingshu.

    When Rebecca Saxon was diagnosed with cancer at the young age of 27, she thought her life was over. But in her darkest hour, inspiration struck and she found a way of turning her misfortune into advantage.

    Following her cancer treatment, Rebecca launched a successful business "Something Blue Bridal Shoes"—a unique range of wedding footwear, which came out of the fashion pictures she drew while recovering in her hospital bed.

    Rebecca, from London, says, "I started designing wedding shoes with blue soles (鞋底) when I was halfway through my cancer treatment. I had a hit when I was diagnosed with cancer but I decided that I was going to pick myself up and fight this cancer. The pictures were my release and the way I got through the many hours spent in a hospital room. I had no idea what was going to happen to me, but I knew I had to be positive if I was going to overcome this treatment. I told myself this was not going to be the end for me. I decided to fight with my negative feelings and start drawing."

    Rebecca had always loved fashion since she was younger. Several of her friends were getting married at the time when she was ill. "So at first, I would be drawing designs for wedding dresses and other clothes. But then I started drawing wedding footwear—designing shoes with blue soles which were very comfortable too. I thought it would be a lovely way of combining the 'something old, something new, something borrowed, something blue' tradition. Drawing really helped me deal with my treatment," said the brave girl.

    With the encouragement of her boyfriend, she turned her dreams into her reality and set up "Something Blue Bridal Shoes". Each beautiful shoe has a blue sole, combining the age-old tradition of what a bride should wear at her wedding for good luck.
