Q: Article: "Gangnam Style" by singer Psy from Korea, is a popular song, but its extraordinary global success is really the result of its music video, which is a great piece of genius. On September 22nd, Guinness World Records listed "Gangnam Style" as the most-liked video in the history of YouTube. It's been performed at West Point (West-Point Style), and Google's CEO, has done the "Gangnam Style" horse dance at the company's office in Seoul. Even Samsung is trying to make Psy the new model for the latest type of fridge. The song's global popularity is such that the vast majority of people who enjoy it don't speak Korean, and have no idea what it is about. That's fine --- part of what makes "Gangnam Style" so fun is, like international pop music, the difficulty in understanding it. When we sing along, "Hey, sexy lady", we don't really know what we're singing about. The joy of _ is familiar to anyone who loves pop music from elsewhere. Anthony Lane, in his 2010 review of the Eurovision Song Contest, Only Mr. God Knows Why, used "Eurovision English" as one of its chief pleasures. It's "a complex tongue, spoken nowhere else, which raises the heartfelt poetry but absolute nonsense to a level of what sci-fi writers could only have dreamed. " In similar ways, "Gangnam Style" is just an over-the-top video where a fat man does a funny dance and sings repetitive words that don't make sense to most of us. But on the other, the magic of the song also lies in its funny dance, which reflects not just cultural morals specific to Korea, but cultural values easily recognizable to western viewers. This song's words may be in Korean, but its scenes are in clear American. The dance moves are simple enough to copy. Nonsense, in other words, forces us to let down our guards. It makes us relax, and asks us to let in all sorts of feelings from which, otherwise, we might distance ourselves. "Gangnam Style" happens to be so interesting because of its incomprehensibleness.

Q: Article: In a nation with a one-child family planning policy, it's understandable for parents to worry over whether they are petting their children. Are the children truly as fragile as sometimes made out to be? The concern has been brought into focus with the popularity of a hit reality TV series, Hunan TV's Dad! Where Are We Going? and Zhejiang TV's First Time In Life. In both, children as young as three have become new public figures. In the show First Time In Life, children chosen from ordinary families are given small tasks to complete by themselves;the ongoing Dad! show centers on five celebrity fathers and their children who are forced to live a simple life in rural areas, far outside their comfort zone. Regardless of their family background, the children's reactions to new environments have struck the public. In one episode of Dad! , the five-year-old daughter of former Olympic diving champion Tian Liang cries and hides behind her father when they arrive at a rural village. In an episode of the other series, a young girl in Tianjin breaks down into a tearful fit after being asked by her father to go out alone to buy eggs and a pancake. In the eyes of some observers, these kids show no sense of independence, and the reason is put down to parents who are overly sheltering. But television viewers and parents were heartened when the sobbing Tianjin girl finally wiped away her tears as she returned holding the pancake. In the case of Tian's daughter, she eventually began to take care of her younger companions and learned to seek help from people she didn't know. The father of the Tianjin girl felt "delightfully shocked" and said. "She used to have to be accompanied by her mother or grandmother. Now she has the courage to do it all by herself. " The shows have led many parents to change how they raise their children. Shanghai mother Liang Jing said she would try to "give some training" to her shy son, asking him to tidy up his toys. Lin Yi, a parenting expert in Beijing, said giving kids a chance to do things for themselves helps to raise their sense of achievement, which carries benefits throughout their lives. "

Q: Article: Many parents watch the news or other shows as children play nearby. But new research shows that even when the television is just background noise,it may be to a child's normal development. It's estimated that 75 percent of very young children in the United States live in homes where the television is on most of the time,even though the kids often aren't watching it. The University of Massachusetts researchers recently studied how TV background noise might affect young children. The study looked at 50 1,2and 3yearolds. Each child came to a lab with a parent and was allowed to play for an hour with various toys. For half the time,a television was on in the room,showing the adult game show as well as advertisements. During the other half hour,the TV was turned off. As expected,the children paid little attention to the adult television show,glancing at it for less than a few seconds at a time,and less than once a minute. Even so,the distraction of the background noise had a significant effect on how children at every age played. When the television was on,the children played with each toy for far shorter periods of time,and focused attention during play was also shorter compared to how they played when the TV was off. Researchers said that even though the children aren't interested in the show,background TV affects their ability to do various types of play. The finding is important because many wellmeaning parents who wouldn't let their young children watch television may not realize that even adult programs that don't interest children still can have an effect. "Background TV is potentially a chronic environmental risk factor affecting most American children," said the lead author of the study. "Parents should limit their young children's exposure ."
