By now, we are all aware that social media has had a tremendous influence on our culture, in

business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends’ new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?

Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.

Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.

Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.

Also, what you carelessly post on the Net can come back to trouble you. Revealing( 泄露) personal information on social sites can make users vulnerable(易受伤害的)to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.

Social media has its advantages and drawbacks as each coin has two sides. It is up to each user

to use social sites wisely to enhance their professional and social life, and exercise caution to ensure

they do not fall victim to online dangers.

Tricks to Learn from Super Sleepers

Do you want to sleep soundly each night and wake up energized the next day? Here’s a peek at some smart,surprising habits of great sleepers.

Exercise early.

Morning fitness class or gym time before work?Go ahead,give it a try.1.While experts aren’t exactly sure why,it could have something to do with morning exercise’s ability to help regulate the secretion(分泌物) of certain hormones involved in blood pressure management, which may lead to better sleep.

If your stomach starts rumbling(发出咕噜声) before bed, try reaching for good-for-you foods that actually promote sleep, like walnuts, tart cherries, or Greek yogurt instead. 2.Eating too much of anything within a few hours of going to bed could suppress(抑制) your body’s ability to produce sleep-promoting melatonin.

The world, in painter Chen Xiao’s eyes, is as colorful and sweet as ice cream.

At the opening of his latest exhibition, Colorful World in the Eyes of Sean Chen, at the National Museum of China recently, the artist told his story.

Chen left China for Australia in 1986 to seek artistic freedom, and like many new immigrants(移民)then, he had little money in his pocket. To make ends meet, he drew portraits of people in the street.

Every day, he saw people buy ice cream from a shop. Chen couldn’t help wondering: “It must taste great, that’s why so many people buy it.” But he didn’t buy one for himself because he had to save money to support his studies. After four months of painting there and watching people eat ice cream, Chen didn’t resist the temptation(诱惑)--- he bought an ice cream. “The first bite took me to heaven,” Chen recalls while laughing. “You know, as a poor young man in a new country, an ice cream was too expensive then.” Since then, he kept the taste of the ice cream in his heart and included the happy feelings in his paintings, which turn out to be colorful and sweet.

His current exhibition is part of his nationwide tour that began at the National Art Museum of China in Beijing in 2011. He plans to take his artworks to 24 cities around China by 2016. The exhibition at the National Art Museum of China will last until April 22. After the exhibition tour, he will sell his works through an auction(拍卖会), and all the money will be donated to protection of the environment in China. “The natural environment of New Zealand has inspired my artwork and brought me enjoyment. I hope people in my home country can enjoy the same beautiful environment as I do,” says Chen, who has made New Zealand his home for the last 26 years.
