Question: Article: Several overseas trips with the family have taught us that they can be rewarding, but you always have to be careful of pickpockets. On a lovely visit to Paris an encounter with a pickpocket gave the would-be thief a little more than he _ While walking down the famous Champs Elysee, I was astonished to feel someone unzip my handbag and remove my purse. I turned to glimpse a young man turning away and pretending to be absorbed in the mouth-watering contents on display in a bakery window. Being only a teenager at the time, I had no idea what to do. So I tapped the young man in question on the shoulder and said. "Excuse me can you please give me back my purse?" Of course the pickpocket had no idea what I was saying (and didn't want to know) and proceeded to shrug his shoulders and basically say (in French) "I don't speak English"? Meanwhile my Mother (a Scotswoman with a bad temper), came to see why I had stopped walking and what was going on. When I informed her of the situation she lost control and started yelling at the thief who still stood there making gestures in French while a crazy Scotswoman harangued him. At this stage we were starting to attract onlookers, and when my Mother started hitting the young man with her handbag the would-be thief decided it was time to get away. Luckily, amid all the disorder the thief lost his control of my purse, and as he made a break-for-it, my purse dropped to the ground! I quickly snatched it up and for the rest of vacation we walked around with our handbags clutched against our chests!

Question: 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.

Question: Article: There are new findings that not enough sleep may cause people to gain weight.Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger. In one study,researchers in the United States examined information on more than 1000 people.The people had taken part in a long-term study of sleep disorders. Some people slept less than five hours a night.They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours.And they had 15 percent less of the hormone leptin.Experts say ghrelin helps make people feel hungry;leptin makes you feel full. The scientists say these hormonal changes may be a cause of obesity in Western societies.They note the combination that limitation is common and is widely available. The results were not affected by how much people exercised.People who are awake longer have more time to burn energy.But the researchers say loss of sleep may increase hunger especially for high-calorie foods,so people gain weight.It seems that,for survival,the body may be designed to store more fat during times with less sleep. Researchers from Stanford University in California and the University of Wisconsin did the study.They found that the best amount of sleep for weight control is 7.7 hours a night. The Public Library of Science published the findings in its journal Medicine.Internet users can read the full study,free of charge,at plos.org.
