Article: School is out for the summer in some areas, and for many children, that means weeks of sleeping in late, trips to the swimming pool or hours spent in front of the TV. These months of inactivity--- away from the daily tiring things of school--- are something that young people look forward to, but it can have a detrimental influence on the knowledge they have. Studies have shown that children lose a lot in math skills during the summer months. Children who spend little time learning experience a much greater amount of learning loss than those who often take part in summer programs. So when school starts again in the fall, teachers often have to spend several weeks reteaching children material that they have forgotten. Experts suggest that parents make sure the summer months are a time of continued learning. For example, they suggest that lunch time is good time to improve a child's spoken skills, simply through conversation. A trip to the supermarket can be an opportunity to improve a child's math skills by having him or her add up the cost of food. And there is no better way to prevent learning loss than by having a child read every day. Fortunately, there are many programs that can help parents. The best place to start is at your local library. Most libraries have summer reading programs that are filled with fun activities. A. strong musical education also improves learning. Find out summer music camps in your area. We think that children should have fun during the summer break, but it should not be a vacation from learning. We strongly suggest parents should take advantage of the many educational opportunities available for their children during the coming weeks.

Article: It would be hard to find a person in America who has never eaten a hamburger, but this popular food was not originally made in America. The original hamburger can be traded back to the Middle Ages, when Russians ate raw meat that was scraped and shredded with a dull knife and formed into patties , It was called Tartar steak. This was the first step in a long series of developments that eventually resulted in hamburger as we know it today. German sailors picked up the raw meat delicacy in their contacts with Russians and brought it back to their home port of Hamburg. But the people there were unused to eating raw meat , so they broiled the outside of the Russian steak; thus the hamburger steak was born. The hamburger steak was brought ot America in the nineteenth century immigrants. Louis Lasssen, a cook in New Haven, Connecticut, modified the hamburger steak by sandwiching it between two pieces of bread. But the true American hamburger came into existence in St. Louis at the Louisiana Purchase Exposition in 1904. A harried cook at the fair quickly slapped broiled beef patties between buns and served them to a demanding crowd, which gulped them down joyously. At first this new food creation was made from scraps of poorer cuts of meat that were not used for anything else, but before scrapes were not enough. The demand for greater quantities of hamburger could only be met by using more and better cuts . Hamburger stands sprang up all over the country, and a side industry of condiments , such as ketchup and relish, grew

Article: In the market of luxury brands, Chinese consumers are only second to the Japanese in the world. Across the globe it's clear that the young generation are increasingly relying on expensive brands for their self-image. Personally I am a fashion-lover, at least in spirit. I love to look at clothes and shoes. But I don't understand why people spend large amounts of money on designer labels. Certainly, young people, whether in China or elsewhere, should be building their self-confidence in other ways. When a young woman shows off a handbag worth two months' salary, that's a scary thing. What are the psychological factors forcing young people to take on debt for designer items? The desire to say, "Hey, look at me. I'm wealthy. I have social status." Scientists have found the acquisition of luxury brands doesn't lead to happiness. Study after study has shown that, although we are born to desire material possessions, when we get them, we don't suddenly become "happy people". In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, have shown that individuals who invest in travel and other experiences get more pleasure than those who invest in material things. That's because experiences are more easily combined into a person's identity. If I travel to Yunnan, that adventure affects how I think. My memories entertain my friends and colleagues. It follows, then, that investing in experiences improves my chances for successful social relationships. Moreover, as Van Boven has observed, young people who pursue happiness through "things" are liked less by others than young people who seek happiness through experiences. This research is pretty solid, but I suspect it won't persuade young people not to desire a style. It's natural to want to express yourself through your appearance. So my advice is, create a look that isn't tied to a designer label. You don't have to _ to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look.
