Owning a smartphone may not be as smart as you think. It may let you surf the Internet, listen to music and snap photos wherever you are…but it also turns you into a workaholic, it seems.

    A study suggests that, by giving you access to emails at all times, the all-singing, all-dancing mobile phone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles.

    The study by technology retailer Pixmania reveals the average UK working day is between 9 and 10 hours, but a further two hours is spent responding to or sending work emails, or making work calls. More than 90 percent of office workers have email-enabled phones, with a third accessing them more than 20 times a day. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess(承认) they are on call almost 24 hours a day, with nine out of ten saying they make work emails and calls outside their normal working hours. The average time for first checking emails is between 6 a.m. and 7 a.m., with more than a third checking their first emails in this period, and a quarter checking them between 11 p.m. and midnight.

    Ghadi Hobeika, marketing director of Pixmania, said, “The ability to access literally millions of apps, keep in contact via social networks and take photos and video as well as text and call has made smartphones invaluable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become , the more is expected of us in a work capacity(容量).”

    Feifei, an 11-year-old boy from Xuzhou, Jiangsu Province, suffered from a sudden acute eye disease which has almost led to blindness. The disease was caused by excessive（过度的）eye fatigue（疲劳）during the winter vacation, during which he played computer games for continuous 10 days and nights.

    Many youngsters in China nowadays are increasingly addicted to computer games and other electronic products. This is followed by a series of health problems, with the most typical case being myopia, or nearsightedness.

    According to the latest research report released by the World Health Organization (WHO),the myopia rate among Chinese teenagers ranks first in the world—70 percent of high school and college students. The rate is nearly 40 percent in primary school students, while it is only 10 percent for their peers in the United States.

    There are at least 10 million people in China with severe myopia, and they are likely to get pathological（病理性的）myopia in middle age. Pathological myopia can't be treated with glasses or surgery, and it is one of the biggest factors that lead to blindness, Xu Xun, director of the ophthalmology（眼科学）department at Shanghai General Hospital, pointed out.

    Experts explain that two major factors lead to the high rate of myopia among Chinese people. One is high academic pressure, and the other one is excessive use of electronic devices over a long period of time .Genetics, on the other hand, are not the main reason, as only 20 percent of Chinese people had myopia in the 1960s.

    "Teenagers are now faced with severe academic pressure, which means they often study without natural light. This increases their risk of becoming nearsighted," Xu said.

    Experts suggest that youngsters maintain a proper balance between study and rest so as to protect their eyesight, and parents should play an active role in the process.

    Most of us will be familiar with the traditional talent show set-up: thousands of hopefuls line up outside the audition（试音）room, wait for hours to go in and perform for a group of judges. Then these potential pop stars could be lucky and get through to the next round, or they might hear the command, "Sorry, it's a no from me. But what do the judges actually bring to a talent show?

    Music talent show judges attract millions of viewers each week to their programs. As public figures, they play an important part in advertising campaigns for these programs. They often receive high salaries and can be moody. Are they really worth the expenses and difficulties that they cause? One solution might be to replace them with computers.

    Can computers really match human judges? Scientist Dr Nick Collins and his team at the University of Sussex think they can. Dr Collins has been working on a project that involves programming three computerized judges that he says would be far more consistent in their judgment of musical performances. Employing a special programming language, Dr Collins's digital judges can be trained up by "listening" to particular musical styles. After they have been listening for a while, the programming language allows these judges to spot the specific features of the music, including the voice quality, the rhythm etc. Collins says, “The judges' listening capacity is not yet as good as a human ear, but they won't be as moody as some human reality TV show judges.”

    Maybe that is the problem with this electronic musical innovation. Real human judges on talent shows interest us with their personality, decisions and catchy phrases. Will a computer program be able to do the same?

    At first, Michael Surrell didn't see the black smoke or flames shooting from the windows of his neighbors' home. Then they got a call from one of his daughters: "The house next door is on fire!" He went over and saw three women crying madly on their porch (门廊).

    "The baby's in the second floor!" one of the women cried. Though the fire department had been called, Surrell, then 64, bravely ran inside. "The baby" was Tiara Roberts, the woman's granddaughter and a playmate of Surrell's three youngest kids.

Entering the burning house was like "running into a bucket of black paint," Surrell says. The thick smoke caused him to stumble blindly around, burned his eyes, and made it impossible to breathe. The conditions would have been dangerous for anyone, but for Surrell, who has chronic obstructive pulmonary disease(慢性阻塞性肺病), they were life-threatening.

    Taking a deep breath, he moved around in the overwhelming darkness. Because the house had a similar layout to his, he found the stairs and made it to the second floor. Then he heard a soft but clear moan. Still unable to see, Surrell fell to his knees on the hot wood floor. He crawled toward the sound, feeling around for any sign of the girl. Finally, he touched something. A shoe, then an ankle. He pulled Tiara toward him, scooped her into his arms and stood. Turning, he fought through the smoke and ran blindly into the blackness…

    Surrell woke up in the hospital a couple of days later and spent over a week in the hospital. Tiara was released from the hospital after a few days. The fire worsened Surrell's pulmonary condition, and he feels the effects even two years later. As a result, he takes extra medication that helps open his airways. "It's a small price to pay," he says. "I'd do it again in a heartbeat. I wouldn't give it a second thought."

Many people influenced various aspects of my life, based on their personal characteristics, accomplishments, and values. I have been fortunate to have had numerous teachers and professors who I respect for their patience and intelligence. There are artists that have inspired me by their natural talents and original creativity. I value many political leaders, who have inspired me by their contributions to society, and their ability to change our futures. But of all the people I have known in my life, the person I admire most is my father.

As the youngest girl in my family, I always considered myself to be "Daddy's little girl". While I grew up, it always made me sad to see so many of my friends and neighbors without a father or father-like figure around. This helped me appreciate how my father always takes an interest in his children's lives. In every aspect of my life my father continuously pushes me to excel, so I could accomplish my work outstandingly among my people. Whenever I feel like giving up, or have a question or a concern, I know I can always call on him for advice. From him I have also learned that sometimes you have to put others' needs ahead of your own, but you should make sure you are not taken advantage of by others. His strength seems to be unbreakable during hard times, and he is extremely determined to accomplish anything he sets his mind on, no matter how tiny it is. I highly respect him for how he stands up for what he believes in, and will never back down. He is a very reserved man, but to everybody's surprise, he has a great sense of humor, and always knows how to put a smile on the faces of his wife, his children and his friends.

Living in his love and instruction, I am very proud of my father. He also professes how proud he is of his children, and is still there to support us in whatever we are involved in.
