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: Shopping in the United States changes a lot.About ninety years ago most people shopped in small stores that were owned by one person or a family.Women went from the bakery to the butcher's to the grocer and on to the fruit and vegetable seller in order to get their food for the week. Then about sixty years ago, supermarkets were born.In a supermarket, people could get all the different kinds of food they needed without going to different stores. The next big change in shopping in the United States was the shopping mall.A shopping mall is a group of stores under one roof.Because malls allowed people to shop without worrying about the weather, they soon became very popular.The mall became a place for people to socialize in addition to shopping.If you walk through a mall, you will see older people sitting, chatting and drinking coffee.Malls are places for teenagers to hang out.Many teens will often just "go to the mall" and spend time with their friends. The recent change in American shopping was the superstore.Large chain stores such as Wal-Mart, Office Depot and Toys "R" Us have been built all across the United States.Because they are so large, they can buy goods at a great discount and sell them much cheaper than smaller stores. Sometimes, when they are built near small towns, many of the small town stores have to close.They just cannot compete with their giant neighbors. And now, online shopping is becoming more and more popular all over the States.People are too busy to go to the physical stores, so they go shopping over the Internet.Online shopping has lots of advantages.For instance, online stores are usually available 24 hours a day.Searching or browsing online shops can be faster than browsing the physical stores.While, online shopping also has its disadvantages.People are at higher risk of being cheated on the part of the merchant than in a physical store.And privacy of personal information may be let out.

Article: A report brought back by most visitors to the US is how friendly, polite, and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the US. Yet American's friendliness and helpfulness is an observation made so frequently that it deserves comment. For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of distraction, and brought news of the outside world. The tough realities of the border also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest settler agent. It was not a matter of choice for the traveler or only a charitable impulse on the part of the settlers. It reflected the hardship of daily life: if you didn't take in the stranger and take care of him, there was no one else who would. And someday, remember, you might be in the same situation. Today there are many charitable organizations which specialize in helping the exhausted traveler. Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist routes. "I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner, amazing." Such observations reported by visitors to the US are not uncommon, but are not always understood properly. The casual friendliness of many Americans should be understood neither as superficial nor as artificial , but as the result of a historically developed cultural tradition. As is true of any developed society, in America a complex set of cultural signals and customs is the basis of all social inter-relationships. And, of course, speaking a language does not necessarily mean that someone understands social and cultural patterns. Visitors who fail to "translate" cultural meanings properly often draw wrong conclusions. For example when an American uses the word "friend", the cultural meanings of the word may be quite different from those it has in the visitor's language and culture. It takes more than a brief encounter on a bus to tell polite customs from individual interest. Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.
