By now, we are all aware that social media has had a powerful 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, besides 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 reconnect 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 take part in campaigns and activities of their choice. Professionals use social media sites like Linkedln to improve 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(网络欺凌) 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 (分心)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. Leaking personal information on social sites can make users easily harmed to crimes like identity theft, stalking(尾随犯罪), 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 improve their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.

“When I grow up, I want to be a runner.” These words are spoken by thousands of Kenyan children. 50 percent of the Kenyan top runners are members of Kalenjin, one minority race of the country. They make up less than two percent of Kenya’s population. This fact has puzzled sports scientists. They have spent considerable time and effort trying to answer one question: What enables the Kalenjin people to run so fast?
Although the question seems simple, finding the answer has proven to be difficult and controversial. A team of Danish sports scientists spent 18 months and discovered the Kalenjins had remarkably slow heart rates even when running long distances. The Kalenjins live in high-elevation（高海拔） villages in the Rift Valley in western Kenya. People living at high elevations produce more red blood cells, which aid in the transport of oxygen throughout the body. Because the air is thinner and contains less oxygen at high elevations, the body produces more red blood cells. Scientists believe there is a connection between increased red blood cells and low heart rates and that both may enable high-altitude athletes to outperform those who train at low altitudes. The Danish scientists also studied the bodies of the Kalenjins and compared them to those of the Danes. They found that the Kalenjins have longer “birdlike” legs. The Kalenjins also have lower body mass indexes (a measure of body fat based on weight and height) and shorter bodies than Danish people.
As a result of the Danish study, some scientists made the conclusion that the Kalenjins possess what is called a “speed gene(基因)”. However, Kenyan runners were offended by this conclusion They credited their success to hard work and endless hours of training.
Although the controversy over the “speed gene” remains unsolved, British runner Mo Farah’s experience offers an interesting perspective on the subject. In 2005, he realized he wasn’t meeting his potential as a runner. A group of Kenyan runners were training in England then. After he accidentally observed the Kenyans’ strict training routines and dedication to their sport, Farah said it was like a switch had been turned on in his head. He began eating healthy foods, going to bed early, and training harder than he had ever trained in his life. As a result, Farah’s running career exploded. He has won seven world and Olympic titles in the 5000m and regularly beats Kenya’s top runners!
Farah’s story proves what Kenyans have known all along. Regardless of genetics, their success would not be possible without hard work, dedication, sacrifice, and mental toughness. Their “secret” is simple. Train hard, run fast, and never give up.

When I was 17, I read a magazine article about a museum called the McNay, once the home of a watercolorist named Marian McNay. She had requested the community to turn it into a museum upon her death. On a sunny Saturday, Sally and I drove over to the museum. She asked, “Do you have the address?” “No, but I’ll recognize it; there was a picture in the magazine.”
“Oh, stop. There it is!”
The museum was free. We entered, excited. A group of people sitting in the hall stopped talking and stared at us.
“May I help you?” a man asked. “No,” I said. “We’re fine.” Tour guides got on my nerves. What if they talked a long time about a painting you weren’t that interested in? Sally had gone upstairs. The people in the hall seemed very nosy (爱窥探的), keeping their eyes on me with curiosity. What was their problem? I saw some nice sculptures in one room. Suddenly I sensed a man standing behind me. “Where do you think you are?” he asked. I turned sharply. “The McNay Art Museum!” He smiled, shaking his head. “Sorry, the McNay is on New Braunfels Street.” “What’s this place?” I asked, still confused. “Well, it’s our home.” My heart jolted (颤动). I raced to the staircase and called out, “Sally! Come down immediately!”
“There’s some really good stuff up there.” She stepped down, looking confused. I pushed her toward the front door, waving at the family, saying, “Sorry, please forgive us. You have a really nice place.” Outside, when I told Sally what happened, she covered her mouth, laughing. She couldn’t believe how long they let us look around without saying anything.
The real McNay was splendid, but we felt nervous the whole time we were there. Van Gogh, Picasso. This time, we stayed together, in case anything else unusual happened.
Thirty years later, a woman approached me in a public place. “Excuse me, did you ever enter a residence, long ago, thinking it was the McNay Museum?”
“Yes. But how do you know? We never told anyone.”
“That was my home. I was a teenager sitting in the hall. Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before. You thought it was a museum. My feelings about my home changed after that. I’ve always wanted to thank you.”
